Description

The invention relates to a device for adjusting an upsetting roller of an upsetting stand.

Upsetting stands are known from the prior art, with which an upsetting roller can be positioned from the side or pressed laterally against the rolling stock, for example when rolling heavy plates onto the rolling stock. Such upsetting structures are made, for example EP 2 265 395 B1 , EP 2 411 165 B1 or JP 01075101 A known that have one or two positions on each side. These upsetting stands comprise a bulky cassette for storing the upsetting roller, which takes up a large installation space and still permits play against the roller and employment in the rolling operation. The preamble of claim 1 is based on the JP S61 56701 A .

To hire a compression roller is according to EP 166 981 B1 a compression frame is known in which a reduction in play between the components of the compression frame is achieved in that a piston-cylinder unit presses a cassette in which the compression roller is accommodated in the direction of the rolling stock, so-called balancing cylinders pushing the cassette into the Pull in the opposite direction. Joints between the components of this upsetting stand are thus made practically free of play, which results in a higher precision for positioning the upsetting roller against the rolling stock.

The upsetting frame according to EP 166 981 B1 is subject to the disadvantage that a piston of the piston-cylinder unit, which presses the cassette and the compression roller mounted therein in the direction of the rolling stock, is spaced from the balancing cylinders articulated thereon. In the event that the forces that are not precisely matched to each other both by the piston-cylinder unit and by the balancing cylinders, there is the disadvantage that the cassette is not guided in an exactly translatory manner, which results in an inaccurate adjustment of the compression roller .

Accordingly, the invention has for its object to provide a device for placing an upsetting roller of an upsetting stand, in which simple translational guiding of the upsetting roller is ensured without the risk of tilting or the like.

This object is achieved by a device with the features of claim 1. Advantageous developments of the invention are defined in the dependent claims.

An apparatus according to the present invention is used to set up an upsetting roller of an upsetting stand, and comprises an upsetting stand, to which at least one balancing cylinder is attached, and a balancing crossbar with a drive side opposite the upsetting stand and a working side opposite the driving side, with the balancing crossbar on its working side a bearing device for the upsetting roller can be attached and on the drive side at least one articulation is provided through which the balancing cylinder is operatively connected to the balancing crossbar. The device further comprises at least one adjustment cylinder which is attached to the upsetting stand and can be operatively connected to the bearing device in the direction of a rolling stock in order to set the upsetting roller against the rolling stock, the pressure force generated by the adjustment cylinder acting on the bearing device along an effective axis , which either intersects the at least one linkage through which the balancing cylinder is operatively connected to the balancing crossbar, or runs directly adjacent to this linkage.

The invention is based on the essential finding that an upsetting roller can be pressed against a rolling stock when the at least one positioning cylinder is actuated, the bearing device in which the upsetting roller is accommodated being pulled in the opposite direction by means of the at least one balancing cylinder in order to thereby to achieve a clearance of the separating joints present between the components of the device. By the effective axis on which the pressure force generated by the adjustment cylinder on the Bearing device acts that intersects at least one articulation or runs directly adjacent to this articulation, it is ensured that no tilting moment is exerted on the bearing device and the compression roller mounted therein and thus there is always a highly precise linear movement of the compression roller, particularly in the direction of the rolling stock.

In an advantageous further development of the invention, two balancing cylinders can be attached to the upsetting stand, the adjustment cylinder then being arranged between the balancing cylinders. Actuators of the respective balancing cylinders are articulated on the drive side of the balancing crossbar, with an additional element being arranged between the upsetting stand and the balancing crossbar, with which an actuating member of the adjusting cylinder can be operatively connected. The additional element has two elongate pressure bolts opposite to the drive side of the balancing cross-beam, which with its longitudinal axis define the effective axis along which the compressive force is exerted on the bearing device. The pressure bolts pass through the balancing crossbar, so that the pressure force of the positioning cylinder is branched onto the two pressure bolts and can be transmitted to the bearing device for the upsetting roller on the working side of the balancing crossbar. For this purpose, the free end faces on the working side of the balancing crossbar can come into contact with the bearing device.

With regard to a pressure pin, by means of which a pressure force is applied to the bearing device or the compression roller mounted thereon, it is to be understood that such a pressure pin can have a suitable cross section, e.g. circular, square, rectangular, triangular or polygonal. For example, a pressure pin with a circular cross section is designed in the form of a cylinder. In any case, the cross-section of the pressure pin is selected in such a way that, on the one hand, sufficient stability against buckling is ensured, and, on the other hand, if necessary, the pressure pin can be guided through a slide bearing.

It should be pointed out that the free end faces of the pressure bolts are not fastened to the bearing device for the upsetting roller, but only - at corresponding actuation of the adjustment cylinder - can come into contact with the bearing device in order to exert a compressive force on the bearing device in the direction of a rolling stock. A resetting of the balancing crossbar, ie in a direction away from the rolling stock, is ensured by actuating the at least one balancing cylinder, the actuating member of which is articulated on the drive side of the balancing crossbar.

In an advantageous development of the invention, the contact point between the actuating member of the adjustment cylinder and the additional element can be curved. For example, this contact point can be designed such that a point contact or a surface contact is formed. This ensures a precise transmission of force between the positioning cylinder and the additional element - in the direction of the rolling stock - without the risk of canting or the like.

In an advantageous development of the invention, the actuating member of the adjustment cylinder can be connected to the additional element by a cylinder head, so that lateral forces which can act on the pressure bolts and / or the additional element, in particular when tapping transversely to the active axis, are reduced or not transmitted to the adjustment cylinder . Such equipment of the adjustment cylinder with a cylinder head can advantageously prevent damage to the expensive adjustment cylinder, in particular when tapping. In this regard, it may be pointed out that the cylinder head is not necessarily cylindrical, but essentially has the property of keeping any lateral forces that may occur that act transversely to the axis of action of the adjusting cylinder away from the adjusting cylinder.

In an advantageous development of the invention, the actuating member of the adjustment cylinder can be connected in an articulated manner to the additional element. This articulated connection ensures that the pressure force generated by the adjustment cylinder always only along the pressure bolts attached to the additional element acts on the axis of action, even if the actuator of the adjustment cylinder should not be exactly parallel to the axis of action.

According to an alternative embodiment of the device according to the invention, two adjustment cylinders can be attached to the upsetting stand, a balancing cylinder being attached between the adjustment cylinders. The adjustment cylinders are connected with elongated pressure bolts which, with their longitudinal axis, define the effective axis along which the compressive force is exerted on the bearing device for the upsetting roller. The pressure bolts penetrate the balancing crossbar so that the pressure force of the respective adjustment cylinder on the working side of the balancing crossbar can be transmitted to the bearing device for the upsetting roller. An additional element is arranged between the upsetting stand and the balancing crossbar, to which an actuating member of the balancing cylinder is connected, the additional element being connected to the drive side of the balancing crossbar by two articulations.

In the last-mentioned embodiment of the invention, there is the advantage that the restoring force generated by the balancing cylinder is transferred to the balancing crossbar via the additional element. The fact that the articulations through which the additional element is connected to the drive side of the balancing crosshead either overlaps the active axis or runs directly adjacent to the active axis ensures that the interplay of tensile and compressive forces acting on the bearing device ensures that at best, no tilting moment is generated and thereby jamming or the like is avoided.

With regard to the balancing cylinder and the adjustment cylinder, it should be pointed out that these components of the present invention do not necessarily have to be in the form of a cylinder, but rather are to be understood as a respective actuating element with which a suitable compressive force or tensile force can be generated. Taking this into account, the balancing cylinder or the adjustment cylinder can be driven hydraulically or electrically. In relation The adjustment cylinder may be pointed out separately that, to simplify it, only one operation can be provided, namely in the direction of a rolling stock, in order to press the upsetting roller against the rolling stock. An actuation of the adjusting cylinder in the opposite direction is not necessary, because when a pulling force is exerted by the balancing cylinder and a corresponding traversing movement of the balancing crossbar, the adjusting cylinder is automatically reset by contact of the bearing device with the free end face of the pressure pin.

In an advantageous further development of the invention, a contact surface can be formed on the bearing device for the upsetting roller, with which the end face of a pressure bolt can be brought into contact system when the assigned adjustment cylinder is actuated. This contact surface can preferably be suitably hardened so that premature wear of this contact surface as a result of frequent contact with the end face of the pressure bolt is avoided.

In an advantageous development of the invention, the contact point between the end face of a pressure bolt and the contact surface of the bearing device can be curved, for example in such a way that a point contact or a surface contact forms at this contact point. This prevents possible tilting between the end face of the pressure pin and the bearing device and ensures precise linear guidance of the bearing device and thus the upsetting roller in the direction of a rolling stock when the pressure pin presses against the bearing device. The arched configuration of the said contact point can be achieved in that the end face of a pressure bolt and / or the associated contact surface on the bearing device are each convex.

With regard to the contact point, it may be pointed out for all of the above embodiments of the invention that the surfaces of the bodies which come into contact with one another can each be curved. As an alternative to this, it is also possible for the bodies that are in contact with one another at the contact point arrive, one body has a convex surface, the other body has a concave surface.

The present invention is characterized by a "slim" and modular design. The interaction of the mechanical components ensures a complete balancing of the device according to the invention, with the elimination of all play in parting lines or the like.

The device according to the present invention can be used in all known compression frame types, regardless of the drive system (above or below the hallway). Here, an area of application for upsetting e.g. can be enlarged even in confined spaces. Finally, maintenance and / or replacement of its components are considerably simplified in the device according to the invention.

It is a further advantage for the invention if at least one displacement transducer is provided in order to be able to draw a conclusion about the current position of the compression roller. For this purpose, the displacement sensor is in signal connection with an evaluation device, by means of which the current position of the compression roller can then be determined.

In an advantageous development of the invention, a control device can be provided which is in signal connection with the evaluation device. Accordingly, a measurement signal from the displacement sensor can be processed in the control device. By means of the control device, the balancing cylinder and / or the adjustment cylinder can be controlled as a function of a measurement signal from the displacement sensor. In this case, the actuation of the balancing cylinder and / or adjustment cylinder can also take place in a controlled manner, the control device for the balancing cylinder and the adjustment cylinder being equipped with a control circuit for this purpose.

In an advantageous development of the invention, the respectively current positions of the actuating members of the balancing cylinder and of the adjusting cylinder can be monitored by displacement sensors. For this purpose, such displacement transducers are arranged adjacent to the balancing cylinder and the adjustment cylinder. Since these displacement transducers are connected to the evaluation device for signaling purposes, a respective current position of an actuating element of the balancing cylinder or of the positioning cylinder can then be determined by the evaluation device. In this context, it is of further advantage if the actuation of the balancing cylinder and / or the adjustment cylinder takes place in dependence on a previously determined position by their actuators, possibly taking into account associated target positions. In this case, the balancing cylinder and / or the adjustment cylinder can also be controlled in a controlled manner, namely by the control device, which for this purpose comprises a control loop.

Exemplary embodiments of the invention are described in detail below on the basis of a schematically simplified drawing.

In the Fig. 1-4 Different embodiments of a device 1 according to the present invention are shown in each case. The same reference numbers are used for the same parts.

Fig. 1 shows a simplified lateral cross-sectional view of the device 1, comprising an upsetting roller 10 and an upsetting stand 12, in which two balancing cylinders 14 are attached. A balancing cross member 16 is arranged between the upsetting roller 10 and the upsetting stand 12 and has a drive side 18 and a working side 19. On the working side 19 of the balancing cross member 16, a bearing device 20 is preferably fastened in a form-fitting manner, the bearing device 20 comprising an upper compression roll chock 21 and a lower compression roll chock 22. The upsetting roller 10 is accommodated between these upsetting roller chocks 21, 22. A translational and preferably horizontal displacement of the upsetting roller 10 is ensured in that the upsetting roller chocks 21, 22 are each slidably received or supported on guide rails F.

The balancing cylinders 14 each comprise actuators 15 which are connected to the drive side 18 of the balancing crossbar 16 by a linkage 24.

In the upsetting stand 12, between the two balancing cylinders 14, an adjustment cylinder 26 is attached, the actuator 27 of which cooperates with an additional element 30. The additional element 30 has, opposite to the drive side 18 of the balancing cross member 16, two pressure bolts 32 which extend through through holes 34 which are formed in the balancing cross member 16 in the direction of the bearing device 20 or the upsetting roller chocks 21, 22.

A front free end of the actuator 27 of the adjustment cylinder 26 can be connected to the additional element 30 via a cylinder head 36. Alternatively, it is also possible to connect the front free end of the actuating member 27 to the additional element 30 via an articulated connection.

At this point it should be pointed out that Fig. 1 only shows a half section of a device according to the invention, as shown by the vertical line of symmetry on the right edge of the image.

The invention now works as follows:
When actuating the actuating cylinder 26, its actuating member 27 is moved outward, in the plane of the drawing Fig. 1 left to right. As a result, the additional element 30, and in connection therewith also the two pressure bolts 32, are moved in the same direction, the free end faces of the pressure bolts 32 then coming into contact with the upsetting roller chocks 21, 22. With their longitudinal axis, the pressure bolts 32 each define an active axis 28, along which the pressure force generated by the positioning cylinder 26 is transmitted to the bearing device 20 and thus to the upsetting roller 10 stored therein. While the adjustment cylinder 26 exerts a compressive force in the direction of the bearing device 20, as explained above, the balancing cylinder 14 exerts a tensile force on the balancing cross member 16. Through the interplay of the pressure force generated by the adjustment cylinder 26 and the tensile force generated by the balancing cylinders 14, the parting lines of the device 1 are advantageously made free of play, which results in a highly precise translatory displacement of the upsetting roller 10 in the direction of a rolling stock (not shown). For the setting of the upsetting roller 10 against the rolling stock, it goes without saying that the compressive force generated by the adjusting cylinder 26 is greater than the tensile force generated by the balancing cylinders 14.

The representation of Fig. 1 illustrates that the effective axes 28, along which the pressure force is exerted on the bearing device 20, runs directly adjacent to the respective articulations 24 through which the actuating members 15 of the corresponding balancing cylinders 14 are connected to the drive side 18 of the balancing cross member 16. Thus, even in the event that the forces of the balancing cylinder 14 on the one hand and the positioning cylinder 26 on the other hand should not cancel each other out or are in equilibrium, the balancing cross member 16 and the bearing device 20 attached to it do not have a tilting moment, which ensures precise positioning of the compression roller 10 remains.

It should be pointed out again that the upsetting roller 10 is positioned against a rolling stock (not shown) only by actuating the adjustment cylinder 26, the pressure bolts 32, which extend through the through holes 34 in the balancing cross member 16 in the direction of the bearing device 20 , press against the upsetting roller chocks 21, 22. At the same time, the balancing cylinders 14 exert a tensile force which acts on the balancing crossbar 16 via the articulations 24 in order to bring about freedom from play between the components of the device 1 as a result. According to a simplified embodiment, the adjustment cylinder 26 can be designed such that its actuating member 27 only exerts a force in one direction, namely in the plane of the drawing Fig. 1 left to right. A reset of the adjustment cylinder 26 in the opposite direction, ie in the plane of the drawing Fig. 1 from right to left, can then take place automatically when the positioning cylinder 26 is set without power and the balancing cylinders 14 continue to exert a tensile force on the balancing traverse 16.

Fig. 2 shows a further embodiment of the device 1 according to the invention Fig. 1 slide bearings 38 are received in the through holes 34 in order to translate the pressure bolts 32 when they are horizontally displaced. Otherwise, the remaining parts correspond to the embodiment of FIG Fig. 2 that of Fig. 1 so that to avoid repetition on the explanation of Fig. 1 is referred.

Fig. 3 shows a simplified lateral cross-sectional view of a further embodiment of the device 1, in which the additional element 30 opposite to the edger stand 12 has two guide bolts 40, each of which is guided in a longitudinally displaceable manner in slide bearings 42 which are provided in the edger stand 12. The guide bolts 40 and the pressure bolts 32 can expediently be formed in one piece.

Fig. 4 shows a simplified side cross-sectional view of a further embodiment of the device 1 according to the invention, which is a combination of the Embodiments of Fig. 2 and 3rd corresponds. This means that in the embodiment according to Fig. 4 both the pressure bolts 32 and the guide bolts 40 are each guided in a longitudinally displaceable manner in slide bearings 34 and 42, these slide bearings being provided in the balancing cross member 16 and the upsetting stand 12. The slide bearings 34 and 42 can be designed as guide bushes. As an alternative to this, it is also possible to design such plain bearings as flat guides or in the form of a spherical design. In any case, the plain bearings are adapted to a respective cross-sectional shape of a pressure or guide pin 32, 40.

In the same way as the pressure bolts 32, the guide bolts 40 can also be suitably designed in their cross-section, e.g. circular, square, rectangular, triangular or polygonal. In particular, in the event that the guide bolts 40 and the pressure bolts 32 are formed in one piece, it is expedient that their cross-sectional shape is identical.

Regarding the embodiments according to the Fig. 2-4 May it be pointed out that the guidance of the pressure bolts 32 or of the guide bolts 40 in the associated slide bearings further improves the precision of a translational displacement of the additional element 30, and the positioning of the compression roller 10 against a rolling stock is thereby optimized.

With regard to all embodiments of the device 1 according to the present invention, it should be pointed out that the balancing cylinders 14 can be designed such that they can have a much larger travel path in the direction of the center of a rolling mill compared to the adjustment cylinder 26. By corresponding actuation of the balancing cylinder 14, it is thus possible to move the bearing device 20 and thus also the upsetting roller 10 into the middle of a rolling train, for example for the purpose of maintenance or an exchange of the upsetting roller 10. With such a wide method of the bearing device 20 in the direction of the center of a rolling mill, the adjustment cylinder 26 is not actuated, the pressure bolts 32 likewise not moving be because their end faces are not attached to the upsetting roller chocks 21, 22.

For the balancing cylinder 14 and the adjusting cylinder 26, displacement transducers 44 can be provided, with which a current position of the actuating member 15 of the corresponding balancing cylinder 14 or the actuating member 27 of the adjusting cylinder can be determined, and in the same way a conclusion about the current one Position of the bearing device 20 and the upsetting roller 10 mounted thereon is possible. For this purpose, the position transducers 44 are connected to an evaluation device (not shown) for signaling purposes.

Furthermore, it is possible to provide a displacement sensor 46 adjacent to the bearing device 20 for the upsetting roller, this displacement sensor 46 also being connected to an evaluation device (not shown) for signaling purposes. Correspondingly, a current position of the bearing device 20 and the upsetting roller 10 mounted thereon in the roll stand can be determined directly by means of this displacement sensor 46 and the evaluation device connected thereto.

For the purpose of simplification, the position transducers 44, 46 are symbolically greatly simplified only for the embodiment of FIG Fig. 1 shown, and can in the same way for the embodiments of Fig. 2-4 be provided.

If displacement transducers 44 are provided both for the balancing cylinder 14 and the adjustment cylinder 26 and a displacement transducer 46 for the bearing device 20, these displacement transducers 44, 46 can be connected to a common evaluation device for signaling purposes.

The balancing cylinder 14 and the adjustment cylinder 26 can be actuated by a control device (not shown). For this purpose, the control device can have a signal connection with the evaluation device, so that the actuation of the balancing cylinder 14 and / or the adjustment cylinder 26 takes place as a function of a measurement signal of at least one displacement transducer. This means that the balancing cylinder 14 and / or the adjustment cylinder 26 are controlled as a function of the respective current position of their actuators 15, 27 or the current position of the upsetting roller 10 in the roll stand, possibly also taking into account assigned target positions. The actuation of the balancing cylinder 14 and the adjustment cylinder 26 by the control device can expediently take place in a regulated form, for which purpose the control device is equipped with a corresponding control circuit. Finally, it should be pointed out that the evaluation device and the control device can also be integrated in a common control device.
