Description

TECHNICAL FIELD OF THE INVENTION

The invention relates to an exchangeable adapter for a crimping machine, by means of which a pressing of a workpiece, in particular a plug with at least one cable or conductor takes place. Furthermore, the invention relates to a group of Wechseladaptern and a crimping machine with multiple Wechseladaptern.

STATE OF THE ART

DE 199 03 194 A1 describes that crimping force during crimping of a workpiece depends on a variety of factors and possibly a complex relationship, for which only a few examples are given below. The crimping force may depend on the conductor and wires of the conductor, in particular variations of the conductor cross section, the material or the composition (alloy), the number of individual wires, the distribution of the individual wires in the wire crimp or the surface of the individual wires (tinned o. ). Also, the crimping force may depend on the electrical contact element which is to be crimped with the at least one conductor. In particular, the crimp force depends on tolerance-related fluctuations in the material thickness of the contact element, the hardness of the contact element, the composition of the contact element, the formation of a so-called groove embossing, the formation of a chamfering of the wire claws, the formation of the transition to the plug or isolation claw area, the surface finish , a possible greasing condition, a length of vein crimps or the length of vein claws (especially if these bump on the ground after curling). Furthermore, the crimping force is influenced by the die, in particular a formation of a Gesenkanfasung (trumpet formation), by the die profile, the die surface, a forming speed u. Ä. Finally, the crimping force of environmental conditions, the actuator, the mechanical chain of action for the operation of the dies, wear, improperly fixed guides, play, external shocks, contamination, faulty components, temperature differences u. depend on.

Conversely, when a crimping force is detected, it is possible to conclude that a correct crimping process is in place. To name just a simple non-limiting example, for crimping a connector with a 19-strand cable, a desired crimp force (or crimp force tolerance range) may be specified. If two strands are missing in the crimped section, this can be recognized by a deviation of the crimping force. For an evaluation of the crimp force, an evaluation of discrete values of the crimp force, in particular of minima and maxima, of the crimp force profile, for example with the detection of time spans or crimping paths between minima and maxima, crimp force changes and crimp force change speeds u. Ä. The result of such monitoring can be used to automatically sort out faulty crimping results. It is also possible that for given samples or even for each crimping a documentation of the crimping force or the Crimpkraftverlaufs takes place. For example, in a plane crash at a later time, it can be ascertained whether a plug possibly connected therewith has been properly crimped, which can then be detected on the basis of the crimp force or the crimp force profile.

It is off to detect a crimping force during the crimping process DE 195 48 533 C2 known to monitor the supply current of an electric motor designed as an actuator for generating the crimping force. If the supply current is smaller or larger than a standard supply current, this can be taken as an indication that the crimping process has not been carried out as desired. Further, during the crimping operation, a height of a crimping die is sensed via a height sensor while a workpiece is being crimped. The measured height is transmitted to a control unit which decides, based on the height, whether the crimping has been performed properly.

For some embodiments known from the prior art, the force sensor is integrated in the force flow from the actuator to the piston moved relative to the anvil, cf. for example. DE 196 22 390 A1 and EP 2 181 602 A1 ,

According to EP 0 902 509 A1 actuates a motor via a gear eccentric, which generates a vertical movement of a tool holder with force sensor and holding fork. On the tool holder, the tool is held, which cooperates with the anvil during the crimping process. A calibration of the force sensor is carried out by the tool holder is coupled to a crimping simulator, in which a second force sensor is arranged. As a second force sensor, a comparatively expensive sensor, in particular a quartz force transducer, find use, by means of which then the built-in tool holder force sensor can be calibrated. EP 0 902 509 A1 also discloses possible evaluations of the crimping force and the Crimpkraftverlaufs to obtain conclusions about the crimping and for deriving error messages.

Also according to DE 43 37 797 B4 a force sensor is arranged in the force flow from an actuator to a relative to the anvil moving punch. In this case, the force sensor is arranged in mechanical series connection between a tool holder and a drive element. The force sensor has an upper and a lower contact surface. While the drive element is supported on the upper contact surface, the lower contact surface transfers the crimping force to the tool holder. The force sensor is arranged in a blind-hole-shaped cavity bounded by the tool holder and the drive element. Here, the sensor is formed with two piezo discs and interposed disc electrode. A connection lug serves to derive the generated charge to an evaluation electronics. About a membrane-shaped force introduction body of the force sensor receiving cavity is hermetically sealed.

EP 1 381 123 A1 discloses a machine-side provided tool holder, which can be moved by a drive in the vertical direction. In the tool holder, an upper tool can be used and locked. The tool holder is provided with a force sensor device which detects the crimping forces occurring on the upper tool. The force sensor device is in this case formed with a housing in which four force sensors are arranged in mechanical parallel connection in the power flow between the bottom and lid. The four force sensors are in this case arranged in a plane which is oriented transversely to the crimp axis.

SOLUTION

The object of the invention is achieved with the features of the independent claims. Further preferred embodiments according to the invention can be found in the dependent claims.

DESCRIPTION OF THE INVENTION

The prior art cited at the beginning is based on the assumption that a sensor is preferably an integral part of the crimping machine, ie it must be firmly and non-replaceably integrated into the actuating kinematics of the crimping machine with continuous electrical connection of the sensor to the electrical power supply and an evaluating control electronics. Possible adaptations of the crimping machine to different crimping processes, for example for different tool or workpiece geometries, take place here in the force flow only "downstream" of the sensor, ie between the sensor and the workpiece.

Deviating from these established basic ideas, the invention proposes for the first time the use of an exchange adapter for a crimping machine, which is formed with an anvil and a stamp. The anvil and the stamp of the removable adapter each have a Gesenkaufnahme on which different die halves can be kept. Optionally, different die halves held on the die receptacles of an anvil and a punch may, for example, have regard to the number of nests, the die contours, the height u. differentiate. Thus, the interchangeable adapter is already used multifunctional, by means of the interchangeable adapter in combination with different die halves different crimping operations can be made possible.

In addition, the anvil and the punch each have a coupling region, via which the anvil and the punch (and thus the removable adapter) can be exchangeably coupled to the crimping machine. For example, different coupling areas allow a coupling of Wechseladaptern with different crimping machines of the same or different manufacturers. Thus, the use of different exchangeable adapter allows an extension of the application spectrum of a crimping machine. It is also possible that over the coupling region alternatively different AC adapter can be coupled with the same crimping machine, which may differ, for example, in terms of size, sensor, swivel or even identical, in which case a wear-dependent replacement can take place

According to the invention, a sensor is integrated into the exchange adapter, via which a crimping force or a force correlating with it, a crimping path or the like can be detected. This embodiment of the invention thus turns away from the prejudice of the expert that a sensor must be a fixed machine component of the crimping machine. Rather, the invention takes into account that different adapter, which can be coupled with the same crimping machine or different crimping machines, each equipped with a sensor. It is made possible according to the invention that, in the event of damage to a sensor, the crimping machine itself does not become inoperable, which is not the case. U. requires a complex expansion of the defective sensor from the crimping machine and the installation of a new sensor. Rather, can be removed according to the invention in a simple manner, the removable adapter with the defective sensor and find another adapter with functional sensor use.

It is also quite possible that different exchangeable adapters for a crimping machine are equipped with sensors with different measuring ranges. If, according to the prior art, a single machine-side sensor is used, it must be designed for the maximum crimping force acting on all possible crimping operations. With a limited resolution of the sensor and the processing of the sensor signal, this limits in particular the measurement accuracy for cases in which the crimping force is only a fraction of the said maximum crimping force. According to the invention, different sensors can be used for different purposes, by means of which then the expected different maximum crimping forces can be detected with high, optimized resolution. According to the invention, moreover, it is made possible that the sensor in the exchangeable adapter is arranged relatively close to the die halves. Since large transmission paths between the die halves and the sensor reduce the accuracy of measurement and increase the influence of errors, the measurement accuracy can be improved with the change adapter according to the invention and the integrated sensor.

In the context of the present invention, there are many possibilities for integrating the sensor into the exchangeable adapter. To name just one example, the sensor may be integrated into the anvil or stamp. It is also possible that the sensor cooperates with both the anvil and with the stamp, in which case the sensor can measure in a direction of action parallel to the crimping movement. It is also possible here that the anvil or the stamp is formed with two anvil parts or two stamp parts, between which the sensor is switched on in the power flow. It is also possible that the anvil or the punch have a recess in which the sensor is arranged. A deformation of the anvil or of the stamp then results in a loading of the sensor arranged in the recess with a force. In this case, the elastically deformed portions of the anvil or punch of the support are mechanically connected in parallel via the sensor. It is also possible that only one of the two support surfaces of the sensor is supported on the removable adapter, while another support surface of the sensor is freely accessible to the removable adapter and interacts with the assembly of the removable adapter in the crimping machine with a counter-support surface of the crimping machine. In this case, the coupling regions or the swaged receptacles may be formed with the support surfaces of the sensor. Preferably, however, both support surfaces of the sensor are integrated into the removable adapter, so that they are not freely accessible and do not have to interact with counter-supporting surfaces of the crimping machine.

For a preferred embodiment of the invention, the removable adapter is equipped with a protective cover. This allows at least partial coverage of the parts of the removable adapter which are moved relative to one another during the crimping process. It is also possible that the protective cover protects the anvil, the stamp, the die halves and any other parts against damage or contamination if the adapter is not connected to the crimping machine and / or stored or transported.

The protective cover may have any shape and size and be made of any material. In a preferred embodiment, the protective cover is at least partially formed with a transparent material, such as Plexiglas. This embodiment is, for example, advantageous if it is desired for the insertion of the workpiece into the crimping machine and into the exchangeable adapter or an exchange of die halves that the interior of the exchangeable adapter is visible. To name just a non-limiting example, the transparent protective cover can also be used to visually monitor the crimping process by the user or by an optical sensor device.

In a further embodiment of the invention, the anvil and the stamp are held captive against each other in the removable adapter, wherein a holder preferably does not block the relative degree of freedom between anvil and punch in Crimprichtung. However, it is also possible that a blockage of the relative position of the anvil and the stamp in non-installed state of the removable adapter takes place while this blockage is canceled with the assembly of the removable adapter to the crimping machine.

It is possible that the anvil and other adapters on the adapter are guided over other elements. In a preferred embodiment, the invention proposes that the anvil and the adapter are guided directly against each other. There are many possibilities for such direct leadership. A particularly simple design of this guide is given when the guide via (at least) a guide pin takes place, which may be carried by the anvil or the stamp. This guide pin can then be guided in a guide recess of the other part, ie the punch or the anvil.

It is also possible that two guide pins are present, via which a rotational degree of freedom of the anvil against the punch is blocked around the crimp axis. Preferably, the two guide pins are arranged on both sides of the Gesenkaufnahmen, which on the one hand results in a compact arrangement and on the other hand can give a rigid guide. It is possible that the guide is permanently effective by one or both guide pins between anvil and stamp. It is also possible that at least one guide acts only over a Teilcrimphub. For the formation of the guide with two guide pins, this means that the guide pins can have different lengths. The shorter guide pin is then only for a Teilcrimphub with the associated guide recess in interaction. For example, the Teilcrimphub at the end of the crimping process take place while for an opening of the punch and anvil, the shorter guide pin spaced from the guide recess and thus the punch or anvil is arranged. This is advantageous, for example, if the shorter guide pin should not block the view of the workpiece with the die halves open, the threading of the workpiece between the die halves or the view of the die halves.

The sensor can basically be arranged at any desired location in the exchangeable adapter, in particular the anvil or the stamp. In a preferred embodiment of the invention it is proposed that the sensor is arranged in a projection in the direction of a crimp axis centered to the Gesenkaufnahme. In this way, for example, a symmetrical loading of the sensor can be achieved. Furthermore, possibly the sensor may be arranged in the force flow, so that a high sensitivity of the sensor can be brought about. Under certain circumstances, it can also be avoided by means of the embodiment mentioned that the sensor is not acted upon merely by a crimping force or a corresponding normal voltage, but by a normal voltage which varies over the surface or even by a moment of significant magnitude.

It is possible that the Gesenkaufnahme is designed only to accommodate Gesenkhälften with only one nest, which is reflected in particular in the required transverse extent of Gesenkaufnahme. In a preferred embodiment, however, the die receptacle is designed to receive a die half with a plurality of nests arranged next to one another. Thus, with the same adapter and the same die halves, the processing of different workpieces with different pressing contours and / or cross sections can be done.

In a preferred embodiment, at least one detachable interface and / or at least one detachable plug is provided on the removable adapter. The interface or the plug serves to supply the sensor with electrical power and / or to transmit an output signal of the sensor to an evaluating control unit. If an assembly of a removable adapter with a crimping machine, then a simple electrical coupling between adapter and crimping machine or other components can be done via the plug or the interface. The replacement of a removable adapter against another adapter then requires (in addition to the mechanical assembly and disassembly) to replace the interfaces or connectors.

It is possible that the removable adapter transmits an output signal of the sensor via the aforementioned interface or a plug to a separately arranged from the AC adapter control unit, which is for example an integral part of the crimping machine and here u. U. also serves for other purposes. In a preferred embodiment, however, a control unit which processes the output signal of the sensor is integrated into the exchange adapter. The thus processed output signal can then be transmitted to an external control unit for further processing via an interface or a plug. ###

The possibilities of processing the output signal of the sensor in the integrated in the AC adapter control unit are many. Without the invention being restricted to this example, a calibration of the removable adapter can take place at the factory or after delivery. Corresponding calibration factors or calibration curves can then be modeled or stored in the control unit integrated in the adapter (and possibly a storage unit of any kind). If the adapter is then in operation, an output signal can be generated via the processing of the output signal of the sensor by the integrated control unit, in which the calibration factor is already taken into account. This has the consequence that the different change adapter already produce adapted output signals, which are already adjusted by the manufacturing tolerances and the calibration factors mentioned.

A further embodiment of the invention relates to a group of interchangeable adapters of the type described above. In this case, the interchangeable adapters of the group of interchangeable adapters can differ in terms of their coupling regions, their sensors, their swivel receptacles and / or plugs or interfaces. Such a group of interchangeable adapters can be offered by a manufacturer, so that a customer from the group can select the appropriate adapter for him. It is also possible that the customer acquires a group of Wechseladaptern, which are intended for different purposes, in particular for the operation of different die halves, sensors, workpieces and / or machine tools.

In a further embodiment of the invention in the group of removable adapter AC adapter with standard interfaces or plugs are provided. A coupling of the different adapter with corresponding counter-interfaces or mating connectors of the crimping machine can then take place via the uniform interfaces or plugs, without further electrical connection work or adaptation work being carried out.

In a particular embodiment of the invention, the different AC adapters of the group have sensors with different measuring ranges. In this way, the adapter can be selected for different applications, in particular with different maximum crimping forces.

Another solution to the problem underlying the invention is given by a crimping machine with several Wechseladaptern the previously explained type or a group of Wechseladaptern.

For a special crimping machine, a control unit is provided which is equipped with control logic. By means of the control logic, a crimping force and / or a Crimpkraftverlauf is determined from the output signal of the sensor, taking into account a calibration factor or a calibration curve. In this case, the calibration factor or a calibration curve can be provided at the factory. It is likewise possible for a calibration factor or a calibration curve to be determined in a customer-side calibration method, for example using a crimping simulator, such as this one EP 0 902 509 A1 is described.

In an alternative or cumulative configuration, different calibration factors or calibration curves can be used by means of the control logic for different adapter, different dies and / or different workpieces to then determine a crimping force and / or a crimp force profile from the output signal of a sensor of the adapter, taking into account the respective calibration factor , For example, the relevant calibration factor or the calibration curve can be specified by the user, which can be done by directly entering a calibration factor or a calibration curve or by entering a type of removable adapter or die halves, then from a file or a map the associated calibration factors or calibration curves be determined. Also possible is an automatic detection of the type of removable adapter by reading a corresponding label, by pressing a sensor of the crimping machine, which detects a shape or an optical identification of the removable adapter u. Ä., In which case, depending on the determined type of sensor, an associated calibration factor or a calibration curve is used.

In the event that a die is used with multiple nests in the removable adapter and in the crimping machine, under certain circumstances, the sensitivity of the sensor and thus the Calibration factor or calibration curve depends on which nest is used for the crimping process. In a preferred embodiment of the invention, the control logic is suitably designed to use different calibration factors or calibration curves for different nests of the die, with which then determine a crimping force and / or a Crimpkraftverlauf from the output signal of the sensor taking into account the calibration factor or the calibration curve. Again, each used nest of the die can be manually entered on the crimping machine or there is an automatic detection.

For improved monitoring of the crimping operation and of the operation of the crimping machine, a sensor for detecting the crimping path may additionally be present on the crimping machine. For example, then a Crimpkraftverlaufskurve be determined in which the crimping force is applied over the Crimpweg. In this case, the sensor may be arranged at any desired location, for example in the case of the actuator of the crimping machine, in the actuating kinematics of the crimping machine, in the interchangeable adapter and the like. ä.

DESCRIPTION OF THE FIGURES

Fig. 1 shows roughly schematically a removable adapter 1, which is formed with a punch 2 and an anvil 3. On the punch 2 and the anvil 3, a respective die receptacle 4a, 4b is provided on the mutually facing end faces, via which die halves 5, 6 are held on the punch 2 and the anvil 3. Furthermore, the punch and the anvil 3 have on the end faces remote from each other via coupling regions 7a, 7b, via which the punch 2 and the anvil 3 can be coupled with a crimping machine 8, which for the illustrated embodiment via an upper part 9 and a lower part 10 (FIG. shown here in dashed lines) of the crimping machine 8 takes place. During the crimping process, the upper part 9 is moved via a crimping path 12 along a crimping axis 11 in the direction of the lower part 10 via an arbitrary actuator, in particular a hydraulic or electric actuator, whereby a crimping force 13 is generated. About the Crimpweg 12 and by means of the crimping force 13, a workpiece, in particular a plug with conductor arranged therein, between the mutually facing end faces of the die halves 5, 6 is pressed in a conventional manner.

• Gemäß Fig. 1 ist der Amboss 3 mit Ambossteilen 15, 16 gebildet, zwischen denen der Sensor 14 aufgenommen ist. Der Sensor 14 besitzt parallel zueinander orientierte Beaufschlagungsflächen 17a, 17b, an welche die zugewandten Stirnseiten der Ambossteile 15, 16 mit der Crimpkraft 13 angepresst werden. Der Sensor 14 erzeugt ein mit der Crimpkraft 13 korrelierendes Ausgangssignal, welches über einen Stecker oder eine Schnittstelle 18 an eine Steuereinheit oder Auswerteelektronik der Crimpmaschine 8 übertragen werden kann. Hier liegt der Sensor 14 in einer Art mechanischer Reihenschaltung im Kraftfluss von dem Unterteil 10 über das Ambossteil 16, den Sensor 14, das Ambossteil 15, die Gesenkaufnahme 4b sowie die Gesenkhälfte 6 zu dem Werkstück. ###

In the removable adapter 1, a sensor 14 is integrated, wherein the type of integration of the sensor in the AC adapter 1 for the schematic representations according to Fig. 1 to 6 different is:

• According to Fig. 1 the anvil 3 is formed with anvil parts 15, 16, between which the sensor 14 is received. The sensor 14 has engagement surfaces 17a, 17b oriented parallel to one another, against which the facing end sides of the anvil parts 15, 16 are pressed with the crimping force 13. The sensor 14 generates a correlated with the crimping force 13 output signal, which via a connector or an interface 18 to a control unit or evaluation of the crimping machine 8 can be transmitted. Here, the sensor 14 is in a kind of mechanical series connection in the power flow of the lower part 10 via the anvil member 16, the sensor 14, the anvil member 15, the die holder 4b and the die half 6 to the workpiece. ###

For the embodiment according to Fig. 2 the sensor 14 is arranged in the region of the die receptacle 4b. In this case, an urging surface 17b of the sensor 14 is supported on the anvil 3, while the other urging surface 17a, which is arranged in the region of the die receptacle 4, is supported on the die half 6. Here, the sensor 14 is arranged in mechanical series connection between the anvil 3 and die half 6. It is also possible, in contrast to the illustrated exemplary embodiment, that the die half 6 is supported in addition to the loading surface 17a via an additional surface formed by the anvil 3 in the region of the die receptacle 4b, whereby a parallel force flow relieving the sensor 14 between the die half 6 and Anvil 3 is possible. Fig. 2 shows opposite Fig. 1 an alternative possibility for the transmission of the output signal of the sensor 14 to the crimping machine 8: Here, the plug or the interface 18 is arranged in the coupling region 7b, so that preferably with the preparation of the connection between the lower part 10 and the anvil 3, the plug or the Interface 18 an electrical connection for transmitting the output signal of the sensor 14 enters with a mating connector or a counter interface 75 which is provided on the lower part 10. (In the Fig. 3 to 6 For simplicity, the cable 14 assigned to the sensor 14 and the plug or interface 18 are not shown, it being clear to a person skilled in the art that for the embodiments shown here the transmission of the output signal of the sensor 14 is as in FIG Fig. 1 or Fig. 2 can be represented or otherwise can take place).

According to Fig. 3 For example, the sensor 14 is disposed in the coupling region 7b. In this case, an urging surface 17a of the sensor 14 is supported on the anvil 3, while the other urging surface 17b is supported on the base 10 in the coupling portion 7b. The power flow takes place here in a mechanical series connection of the lower part 10 via the sensor 14 to the anvil 3, wherein, (as in Fig. 3 is shown schematically), a parallel flow of force to the path above the sensor 14 can be made by additional contact surfaces between the anvil 3 and lower part 10.

For the in Fig. 4 illustrated embodiment, the anvil 3 has a recess 19 in which the sensor 14 is arranged. In this case, the application of pressure to the sensor 14 requires that an elastic deformation of the anvil 3 as a result of the crimping force 13 takes place in deformation regions 20a, 20b, which are arranged in particular laterally of the sensor 14. Thus, in this case, part of the crimping force 13 is absorbed by the deformation regions 20a, 20b, while the other part is applied to the sensor 14.

According to Fig. 5 the sensor is arranged parallel to the power flow between the die halves 5, 6, in which case the sensor 14 is supported both on the punch 2 and on the anvil 3 with its loading surfaces 17a, 17b, which in the region of the die holders 4a, 4b can be done or off the same. In this case, the sensor 14 has a deformation region 21 which enables the crimping path 12. For the illustrated embodiment, the sensor 14 is effective over the entire crimping path 12. It is entirely conceivable that the sensor interacts with the punch 2 and the anvil 3 with a kind of play, so that the sensor 14 is acted upon only in one end region of the crimping path 12. In this case, the sensor 14 may be fixed on one side to the punch 2 or anvil 3 and come to rest on the anvil 3 or the stamp 2 only after overcoming the game. It is also possible that a part of the sensor 14 is attached to the punch 2 and another part of the sensor 14 is attached to the anvil 3 and the two parts of the sensor 14 only after overcoming a game interact with each other. ###

Fig. 6 schematically shows a sensor 14, which is fixed here both on the punch 2 and on the anvil 3. It is possible that this sensor, as for the previously described embodiments, is designed as a force sensor of any design. According to Fig. 6 However, a relative movement of two sensor parts, which are carried on the punch 2 and on the anvil 3, can be detected, so that in this way the sensor 14 can be designed as a displacement sensor. It is understood that in the removable adapter 1 and cumulatively a displacement sensor and a force sensor can be used.

• die Achse y eine Längserstreckungsachse der Gesenkhälften 5, 6 sowie eine Richtung, in welche in noch im Folgenden beschriebener Weise der Stempel 2 und der Amboss 3 in die Kopplungsbereiche 7a, 7b eingesetzt werden sowie
• die Achse x eine Querachse der Gesenkhälften 5, 6, welche vorzugsweise der Längsachse des Steckers und des Kabels in den Wechseladapter 1 eingelegtem Zustand entspricht.

Fig. 7 shows in a greater degree of detail a possible embodiment of a crimping machine 8, in which between the lower part 10 and a concealed upper part 9, an exchange adapter 1 is inserted. By referring to the coordinate system used in the following figures

• the axis z is a crimping axis, which may be inclined slightly backwards relative to the vertical,
• the axis y is a longitudinal axis of the die halves 5, 6 and a direction in which in the manner described below the punch 2 and the anvil 3 in the coupling regions 7a, 7b are used and
• the axis x a transverse axis of the die halves 5, 6, which preferably corresponds to the longitudinal axis of the plug and the cable inserted into the removable adapter 1 state.

While the coupling region 7b frontally in Fig. 7 can be seen, the coupling portion 7a is covered at the front by a cover plate 22 which is held in its closed position by an actuatable by means of a Allen tool locking screw on the crimping machine 8. In the illustrated position, the cover plate 22 secures an exit of the anvil 3 from the coupling region 7a - rather, the removal of the anvil 3 from the crimping machine 8 is possible only with elimination of the cover plate 22.

Fig. 8 shows the attachment of the removable adapter 1 via the punch 2 and the anvil 3 to the upper part 9 and the lower part 10 of the crimping machine 8. According to Fig. 8 For example, the coupling portions 7a, 7b of the punch 2 and the anvil 3 are each formed with a T-shaped extension 23 which interacts with counter-coupling portions 24a, 24b formed by the top 9 and the bottom 10. For the illustrated embodiment, the counter-coupling portions 24a, 24b are formed as T-slots 25, 26, whose longitudinal axis are oriented in the direction of the y-axis. For the illustrated embodiment, the T-grooves are formed by holding elements 27, which are fixed to a base body of the upper part 9 and lower part 10. In Fig. 8 Furthermore, a positioner 28 can be seen, via which the workpiece, in particular the plug with conductor, can be introduced in a predetermined relative position between the die halves 5, 6 and can be held here before and / or during the crimping process. The positioner 28 has a predetermined by a pivot pin 29 pivot axis 30, arranged in the upper end region of the pivot pin 29 latching device 31 and about a pivot axis 32 which is oriented parallel to the y-axis, under the action of a spring Holding device 33, here in the form of an angled holding plate, by means of which the workpiece is fixed in the positioner 28.

In Fig. 8 and 9 are handling members 34 to recognize, which are attached here to the anvil 3. These extend parallel to the x-axis and are formed for the illustrated embodiment with possibly rotatable bolts or sleeves. The changing adapter 1 or the anvil 3 can be held in the fingers of the user via the handling members 34 and can be guided over the coupling regions 7 during the bringing about of the coupling. Furthermore, it can be seen that according to Fig. 9 are held in the region of the die holders 4a, 4b of the punch 2 and the anvil 3 on these die halves 5, 6, whose longitudinal extent is oriented parallel to the y-axis. Furthermore, in Fig. 9 two on both sides of the die halves 5, 6 arranged and supported by the anvil 3 guide pins 35, 36 to recognize. The guide pins 35, 36 occur to guide the crimping movement between the punch 2 and the anvil 3 in interaction with guide recesses 37, 38 of the punch. 2

As in the cut in Fig. 10 can be seen, the front, the user of the crimping machine 8 facing guide pin 35 is shorter than the rear guide pin 36. The guide pins 35, 36 are received with a press fit in corresponding, oriented in the direction of the z-axis holes of the anvil 3. Escape to the guide pins 35, 36 of the punch 2 is penetrated by the guide recesses 37, 38, in which it is for the illustrated embodiment are holes whose diameter forms a clearance with the diameter of the guide pins 35, 36. Due to the different length of the guide pins 35, 36, the front guide pin 35 comes only during the actual crimping, so not during any Leerhubs to effect. It is also possible that the front guide pin 35 comes into effect only for a final phase of the crimping process. If, however, a wide opening of the punch 2 relative to the anvil 3, the guide pin 35 is spaced from the punch 2, which has the advantage that the user can look from the front into the interior of the removable adapter 1 and also on the die halves 5, 6 can check as well as the insertion and the position of the plug and the conductor.

According to Fig. 9 and 10 is an exemplary embodiment of the coupling of the die halves 5, 6 with the punch 2 and the anvil 3 in the region of the die holders 4a, 4b shown. The die halves 5, 6 are basically plate-shaped and can be inserted into a corresponding slot, a recess or groove 39, 40 of the punch 2 and the anvil 3. Transversely to the plate-shaped base of the die halves 5, 6 support and centering pins 41 extend are oriented parallel to the x-axis and in accordance with the section Fig. 10 are arranged at the corners of a rectangle. Two such support and centering pins 41 are respectively arranged on the punch 2 and on the anvil 3. The support and centering pins 41 are in half-shell-shaped receptacles 42 on both sides of the slots, grooves or recesses 39, 40, which are formed by the female retainers 4a, 4b. In this way, on the one hand exact positioning of the die halves 5, 6 guaranteed. On the other hand, via the support and centering pins 41, a support of the crimping forces 13 between the die halves 5, 6 and the punch 2 and the anvil 3. In addition, the die halves 5, 6 each with a screw 43 on the punch 2 and the anvil attached. The screws 43 extend parallel to the x-axis. Furthermore in Fig. 10 shown is a securing bolt 44 which is guided in a bore of the lower part 10 displaceable in the direction of the z-axis and via a spring, not shown in the in Fig. 10 effective position. In this position, the securing bolt 44 extends through a recess 45 of the anvil 3, which is positively avoided that the anvil 3 in Fig. 10 can be pushed out of the T-slot 26 to the left. Indirectly hereby as a result of the coupling by the guide pins 35, 36 u. U. also prevented a corresponding exit of the punch 2. An additional backup of the punch 2, as explained above, through the cover plate 22. If the removable adapter 1 are removed from the crimping machine 8, the locking pin 44 must be manually operated down, which can be done via an actuator 46 which in Fig. 7 is shown.

According to the embodiment in the Fig. 7 to 10 are the coupling portions 7a, 7b formed with the T-shaped extensions 23 and the recess 45 and a suitable contact surface of the punch 2 for the cover plate 22, which on the one hand, the interchangeable coupling of the removable adapter 1 with the crimping machine 8 is enabled and on the other hand, a fuse mounted Position is possible. The Gesenkaufnahmen 4a, 4b of the removable adapter 1 are formed for the illustrated embodiment with the slots, recesses or grooves 39, 40, the receptacles 42 and the bore or a thread for the screw 43, whereby a replaceable attachment of the die halves 5, 6 on the Stamp 2 and the anvil 3 is possible.

Fig. 11 to 14 show interchangeable adapter 1 a, 1 b, 1 c, 1 d, with which a group of Wechseladaptern can be formed as they can be distributed by a company for the purpose of using different die halves 5, 6 and coupling with different crimping machines 8. For the adapter 1 in the Fig. 11 to 14 the coupling regions 7a, 7b are formed identically so that they can be intended for use in a specific crimping machine 8 or crimping machines with matching coupling regions.

As Fig. 11 shows, the coupling portions 7a, 7b may have in addition to the extensions 23 guide grooves 47, which can cooperate with corresponding projections of the upper and lower parts 9, 10. Fig. 11 shows a removable adapter 1 according to the in the Fig. 8 to 10 illustrated embodiment in which the Gesenkaufnahmen 4a, 4b are formed with the receptacles 42 and a bore 48 for the screw 43.

Fig. 12 shows a removable adapter 1 b with different configuration of the Gesenkaufnahmen 4a, 4b: Here, the Gesenkaufnahmen 4a, 4b each have a extending in the direction of the y-axis projection or web 49, which has a substantially rectangular cross-section in an xz-sectional plane, the in Direction of the y-axis is constant. These die holders 4a, 4b are intended for die halves 5, 6 which have slots, grooves or recesses on the sides facing the die receptacles 4a, 4b, which have a cross section corresponding to the webs 49. If the die halves 5, 6 are mounted on the die receivers 4a, 4b, the die halves 5, 6 embrace the webs 49a, 49b in a U-shape. In addition, in the projections or webs 49, a transverse bore extending in the direction of the x-axis is introduced, through which a complementary, the attachment serving screw 43 extends or can be screwed. Thus, the Gesenkaufnahmen 4a, 4b are formed in this case by the combination of the webs 49 with the screws 43 or the bore or the thread for this. In addition, the die halves 5, 6 abut the end faces on abutment or guide surfaces 50 of the punch 2 and the anvil 3 and be guided here.

For the in Fig. 13 illustrated embodiment, the Gesenkaufnahmen 4a, 4b are formed with extending in the direction of the y-axis slots, recesses or grooves 51, in the formed by the die halves 5, 6 webs or projections can occur, in which case the die halves 5, 6 with a paragraph can be supported on the upper side of the female receptacles 4a, 4b. It is also possible that the die halves 5, 6 plate-shaped are of a geometry such that they can be inserted into the slots 51. For fixing the die halves 5, 6 in the die holders 4a, 4b, the die holders 4a, 4b have through holes 52 extending in the direction of the y-axis, through which a pin or a screw can extend, which also has a corresponding through bore of the die halves 5, 6 interspersed. In the interchangeable adapter 1c, the swivel receptacles 4a, 4b are thus formed with the slots, grooves or recesses 51 and the through-holes 52.

The adapter 1d according to Fig. 14 has a significantly in the direction of the y-axis enlarged extent, which can serve to accommodate correspondingly enlarged die halves 5, 6. In the interchangeable adapter 1d, the swivel receptacles 4a, 4b are formed with in a first approximation parallelepiped-shaped receiving spaces 53. The receiving spaces 53 are each open on one side in the direction of the x-axis. In the opposite the receiving space 53 bounding walls recesses or grooves 54 are formed. In these grooves 54 are projections, webs or ribs, which are frontally formed by the die halves 5, 6, added. Preferably, the die halves 5, 6 are held in the die receivers 4a, 4b by a frictional engagement between the projections, ribs or webs and the grooves 54. For the in Fig. 14 illustrated embodiment, punch 2 and anvil 3 are each formed in two parts with a base body 55, in which a holding body 56 is inserted in the direction of the x-axis. The receiving spaces 53a, 53b are delimited with approximately central division of the base body 55 and the holding body 56. Here, the surfaces 54 bounding the groove whose surface normal is oriented in the direction of the X-axis, on the one hand by the base body 55 and on the other hand limited by the holding body 56. With the insertion of the holding body 56 in the base body 55 and pressing the holding body 56 in the direction of the base body 55, for example via a screw, the lateral boundary surfaces of the grooves 54a, 54b of the holding body 56 in the direction of the opposite boundary surfaces of the grooves 54a, 54b, the are formed by the base body 55a, 55b are pressed, whereby ultimately a compression of the projections, webs or ribs of the die halves 5, 6 can be carried out in the grooves 54. In the area bounding the receiving spaces 53, the holding body 56 is U-shaped in a section in the xy plane, the ends of the parallel side limbs of the U delimiting the grooves 54a, 54b. It is possible that the transverse leg of the U is extended beyond the side legs to provide a mounting area for a screw acting between the base body 55 and the retaining body 56 (in FIG Fig. 14 not recognizable).

It is understood that the embodiments of the die receptacles 4a, 4b shown on the one hand and the coupling regions 7a, 7b in the figures are merely exemplary.

Fig. 15 shows a change adapter 1a according to Fig. 11 , which is equipped with an additional protective cover 57a. The protective cover is formed in a rough approximation as a hollow cuboid with constant wall thickness, the hollow cuboid being open at the top and bottom, so that the stamp 2 and the anvil 3 can enter the protective cover 57a from above and below. Through the handling members 34, which extend through bores of the protective cover 57 a, the protective cover 57 a is fixed to the anvil, while the punch 2 during the crimping operation can perform a relative movement to the protective cover 57. It is possible that the protective cover 57a has in the direction of the xy-axis extending lug plates 58, with which handling surfaces are formed. In the region of the walls extending in the yz-plane, the protective cover 57a has approximately rectangular recesses 59 which are closed at the edge, through which a workpiece, in particular the plug with lead, extend into or out of the exchangeable adapter 1a during the crimping process can and / or to a certain extent a manipulation of the limited by the protective cover 57 a interior space is possible. The protective cover 57a is made of transparent Plexiglas, so that also by the protective cover 57a by the user, preferably viewed in the direction of the y-axis, the view of the die halves 5, 6 and the workpiece before, during and after the crimping possible is.

The protective covers 57 may be individualized for the different exchangeable adapters 1a-1d. Exemplary shows Fig. 16 a protective cover 57d, which for a removable adapter 1d according to Fig. 14 is used. It can be seen here that the size of the hollow cuboid for the protective cover 57d is adapted to the enlarged extent of the removable adapter 1d in the direction of the x-axis. In addition, here, instead of the two rectangular recesses 59 according to Fig. 15 a single recess 59 insert. This recess 59 is formed with two circular partial recesses 60 of the walls, which extend in the direction of the YZ plane. The two partial recesses 60 are connected to one another via a slot 61 running in the xy axis along the circumference of the protective cover 57d.

According to Fig. 17 For example, the die halves 5, 6 used in the exchangeable adapter 1 can be formed with a plurality of nests 62a-d formed adjacent to one another in the direction of the Y-axis, which can differ in size and / or geometry. While in the preceding figures, the sensor 14 is not shown in the removable adapter 1, is in Fig. 17 the sensor 14 is symbolized. In this case, the sensor 14 is arranged at a projection in the direction of the crimp axis 11 centered to the die halves 5, 6. If a workpiece is pressed in the nest 62c, the sensor 14 is arranged centrally and in the direction of the crimp axis 11 behind the nest 62c, so that a large proportion of the crimping force 13 passes over the sensor 14 and / or a symmetrical loading of the stamp 2 and of the anvil 3 and the sensor 14 takes place. On the other hand, asymmetric loading of the punch 2 and the anvil 3 takes place when the nests 62a, 62b, 62d are used to varying degrees, and the crimping force 13 only extends over the sensor 14 with a reduced proportion. This reduced proportion can be taken into account by means of an adapted calibration factor ,

Fig. 18 shows the use of the removable adapter 1a with other die halves 5, 6, wherein in these die halves 5, 6 only three nests 62a-c are used and they have a changed Gesenkkontur.

According to Fig. 19 and 20 can permanently or optionally the removable adapter 1 equipped with a positioner 28. With regard to the basic design options, the degrees of freedom of movement of the positioner, the operative connection between positioner and workpiece and the attachment of the positioner to a punch or anvil is, for example, the patent application DE 10 2010 061 148 A1 and referenced therein further publications. In Fig. 19 and 20 By way of example only, one possible embodiment of the positioner 28 is shown without any intention that the invention be limited thereto. Fig. 19 shows the positioner 28 in a kind of exploded view with a fixed to the anvil 3 base body 63 and a separately shown pivoting body 64. On the base 63 of the pivot pin 29 is held, whereby the pivot axis 30 is predetermined. Swivel body 64 has a bore through which the pivot pin 29 extends in the assembled state.

In the in Fig. 20 illustrated position, the holding device 33 is closed, so that held in the positioner, the workpiece, fixed and in a predetermined position and position brought is. Furthermore, the pivoting body 64 is pivoted about the pivot axis 32 from an open position to a closed position, whereby the workpiece is brought into a predetermined position and orientation to the die halves 5, 6. This pivotal position of the pivoting body 64 is secured by one, preferably two redundant fixing devices. According to the illustrated embodiment, main body 63 and swivel body 64 have a fixing device via magnetic elements 65, 66, which the swivel body in the in Fig. 20 apply shown pivot position. Preferably, the magnetic elements 65, 66 come in the pivot position according to Fig. 20 to abut each other. Furthermore, a positive locking element 67 can be provided for a redundant fixation.

Fig. 21 schematically shows the signal and energy flow in a removable adapter 1. The sensor 14 is supplied with electrical energy via a plug or an interface 18. The output signal 68 of the sensor 14, which correlates with the crimping force 13 according to a previously determined dependency, is fed to a control unit 69 integrated in the interchangeable adapter 1. In the control unit 69, a modified output signal 70 supplied to the plug or the interface 18 is determined. Here, the modified output signal 70 may be determined from the output signal 68 via a constant calibration factor or a calibration curve (or other dependency). For this purpose, the calibration factor 72 or the calibration curve 73 can be stored in a memory 71, which can then be read out from the memory 71 by the control unit 69. The calibration factor 72 or the calibration curve 73 can be stored at the factory in the memory 71 or taken into account in a control logic of the control unit 69. It is also possible that with commissioning of the crimping machine 8 an individual calibration takes place with storage of the calibration factor 72, the calibration curve 73 or the other dependency in the memory 71. It is possible that different calibration factors 72 or calibration curves 73 are used depending on which of the Nests 62a, 62b, 62c, 62d is in use. Different calibration factors 72, calibration curves 73 or other dependencies can also be used for different changeable adapters 1a, 1b, 1c, 1d. The modified output signal 70 is then likewise transmitted via the plug or the interface 18 for further processing and / or for the documentation thereof to a counter-interface 75 of an adjacent component, in particular the crimping machine 8.

For the in Fig. 22 shown modified embodiment, the control unit 69 and memory 71 are externally formed and arranged by the AC adapter 1, for example at any point of the crimping machine 8. Preferably, in this case, the memory 71 and the control unit 69 form a unit 74 Fig. 22 the output signal 68 of the sensor is transmitted directly to a plug or an interface 18. The plug or the interface 18 cooperates with the mating connector or the counter-interface 75, via which the output signal 68 of the control unit 69 is supplied, where then the corresponding processing to a modified output signal 70 using the calibration factor 72, the calibration curve 73 or the other dependency and further processing, in particular a documentation, successes can take place.

In the description of the figures are with the letters a to d changeable adapter 1 with different design, in particular with regard to the design of the swaged mounts 4 and / or the coupling regions 7, characterized. In other cases, the letters a and b are used to distinguish functionally equivalent components as to whether they interact with the stamp (mark with the letter a) or on the anvil (mark with the letter b) stand.
