Abstract

A method and an apparatus for the production of sliding-bearing shells from laminated composite material in strip form, in which the laminated composite material fed into the production process as a strip material is processed in successive stages of a plurality of different processing steps, each executed as working strokes, in a plurality of successive stations until the sliding-bearing shells are complete, is improved by dividing the strip material into individual blanks lying transversely to the direction of transfer right at the beginning of the processing operation. These blanks are then separated but transported from processing station to processing station in common stepwise feed, a constant spacing between successive blanks in the direction of transfer being established. This makes it possible to carry out all conceivable mechanical processing methods, whether these are embossing and forming steps or steps involving machining. Waste and chips can be removed in an effective manner by virtue of the separate guidance of the blanks at a mutual spacing. The sliding-bearing shells leaving the continuous production process are thus finished except for machining the sliding surfaces and any additional surface coating.

Description

The invention relates to a method for producing semi-cylindrical plain bearing shells from a band-shaped layered composite material, in which the layered composite material supplied as the material strip to the manufacturing process in successive stages of a plurality of different processing steps, each executed as working strokes, in a plurality of successive stations of a processing device apart from - of the sliding surface machining - subjected to completion of the slide bearing shells and for this purpose is simultaneously transported in feed steps between the working strokes from station to station of the processing device.

The invention also relates to a device for carrying it out this procedure in one with a common drive Direction to open and close the tools in the under different stations and one the series of the successive continuous stations for the Layered composite material and the workpieces formed from it.

Processes and devices of this type for the production of Plain bearing shells made of strip-shaped composite material, in which a material strip in a with a plurality of Stations equipped processing device in plain bearings shells are processed in a variety of ways known guides, for example from DE-AS 16 77 165, DE-OS 21 74 633, DE-AS 22 35 933, US-PS 32 06 830, GB-PS 3 36 333 and GB-PS 6 63 476. All of these known methods and pre directions is common that the material strip before the Zer divide into individual blanks or bearing shell moldings is subjected to a considerable number of processing steps. This has the defect that the individual processing processing, in particular embossing and upsetting processes, dimensional changes in the material strip in Wander  add direction of the tape so that with increasing length the section of the material strip subjected to processing, with increasing number of processing stations that Alignment accuracy of the belt compared to that in each station tools included becomes more and more defective. For the precise processing is of crucial importance speed that exact alignment of the band section to be processed against the tools contained in each station is accomplished. Another shortcoming is that cutting Be work steps on the coherent material strip in in practice are not feasible because of that contiguous strip of material not for processing required variety of leadership opportunities and the required access to the workpiece for the tools are given for machining. Above all, so far resulting chips are not with the necessary security and Completeness of the material strip must be removed to ensure safe and accurate workflow with sufficient precision to be able to ask.

In contrast, it is an object of the invention, the individual Bear steps by better, more precise alignment of the individual material sections compared to those in all stations the processing device arranged tools to ver better, better access for tools for machining to create the workpiece, as well as the possibility of safely and completely remove any machining chips, around the workpieces before feeding them to the next processing step to be able to bring them into a suitable, clean condition Way to get products of significantly improved quality.

This object is thereby ge in the inventive method triggers that the material strip already at the beginning of the processing aisles in individual boards lying transversely to the transfer direction, each a circuit board for a plain bearing shell, divided and these separate boards in one step  wise feed transported through the processing stations and at the same time separately in the processing stations from each other, subjected to the respective processing steps , after each transfer step and before each Bear step aligning the respective boards or of the respective workpiece or molding.

At any stage where it appears necessary, suitable cleaning of the circuit boards or the respective plant Pieces are provided, for example by suction Chips and the like

By early separation of the material strip into individual ones Blanks become any retroactive effect of a processing step on a band section on adjacent band sections closed. The separate alignment of the boards or Workpieces or moldings in each station allow execution with high precision. If for any reason, at for example, tool damage or material defects errors or defects in a circuit board during processing result from a workpiece or molding or become apparent, this has no influence on the processing of other boards or workpieces or moldings. With defects or errors Tied strip sections can be ejected early as boards will. The simultaneously on the different boards or Workpieces to be carried out under be of all kinds without influencing each other. This allows you to easily get into the machining process Steps for machining the blanks or workpieces or moldings are included. For example, in method according to the invention in the slide bearing shells seeing circumferential grooves through broaching and / or embossing in the boards attached before forming into plain bearing shell moldings will.  

The order of the processing steps to be carried out on the blanks or workpieces or moldings can be set up in accordance with aspects of optimal machining mode and achieving optimum precision, without having to take into account the guidance and transfer of the material or the blanks or workpieces or moldings. For example, the machining of the partial surfaces provided on the plain bearing shells - including their finishing and deburring - can be carried out on the blanks before they are formed into plain bearing shells.

The forming can be carried out in the context of the method according to the invention of the finished printed circuit boards under setting the end applicable circumferential length, the final axial width and below Formation of the final back contour of the plain bearing shells be made. He offers that in this respect too Processes according to the invention complete freedom for processing every single workpiece. The method according to the invention offers the possibility of reshaping the finished bear processed boards while maintaining the previously formed Geometry, in particular the previously formed groove or grooves, to make in final form.

Punching the required holes and cutting and / or embossing locking elements and the like. can in the frame of the method according to the invention after the forming semi-cylindrical plain bearing shells are made.

The method according to the invention can be carried out in the context of the invention, a device in which a with a common drive device for opening and Closing the tools in the different stations and one through the series of consecutive stations ongoing transfer device for the layered composite material and the workpieces or moldings formed therefrom becomes.  

According to the invention, a trans fer device is to be used in such a device, which is designed and adapted to the devices of the individual stations in such a way that the individual circuit boards are gripped by the transfer device after separation from the material and brought into the transfer direction at a predetermined mutual distance and are transported with this mutual distance through the processing stations. In this way, not only an early separation of the material strip into the individual boards is made possible, but also a sufficient mutual distance between the boards to be machined, which allows free access to the tools all around each individual board and thereby any mutual influence of the machining steps on the individual boards, that is, feedback from board to board. By setting a mutual distance from board to board, the cleaning of the boards after one or the other processing step - if necessary - much easier, so that processing residues, chips and the like. can be removed completely and safely before a board or workpiece is moved to the next station for the next processing step.

It is conceivable that the transfer device is more or less unun broken through the entire device. It but is also possible to transfer the device with two or to train more sections, for example a part Section for the transfer of the boards and a section the semi-cylindrical bearing shells formed from the blanks Moldings. The gripping and holding elements are in any case optimal to the conditions of the plates and the semi-cylindrical Adaptable bearing shell moldings. This applies in particular to Use of different gripping and holding elements in the Sections of the transfer device for boards and half cylindrical moldings.  

If the facilities for the application of circumferential grooves in the boards at least one equipped with embossing tools Station included, this station should be within the scope of the invention in the transfer direction in front of the station or in front of the stations for machining the axial end faces for the plain bearing shell be arranged. The facilities for manufacturing from circumferential grooves desired on the slide bearing shells to three successive stations contain distributed facilities. For example, there is a sequence of three Stations are considered as processing steps: Room-Room-Room or Room-Emboss-Room or Room- Re-stamping or other suitable sequences. of advanced and machining steps.

Machining the axial end faces for the plain bearing shells in two successive stations can be done by machining facilities are carried out at the transfer level transverse to the direction of transfer between these neighboring stations can be passed through and at the same time along the side edges of the boards used in this station for simultaneous Machining these two boards are performed. That through aligning the successive ones at a distance from one another Boards in the two neighboring stations an exact and Constant distance dimension over the entire length of the board is guaranteed can with that between the two neighboring Boards processed transversely to the transfer direction not only a high-quality end face machining be made, but also the exact and over the whole to get prepared. The precise adjustment of the axial length The plain bearing shell can then be compressed by a simple compression process will be finally discontinued.

It is similar with the installation of chamfers the later axial end faces of the plain bearing shell. Also  this processing step can be performed on two boards at the same time are made, which are used in neighboring stations will. There can also be an intermediate for this processing step the two neighboring stations across the transfer direction performed processing device are executed.

So far processing operations, especially machining gears on the later partial surfaces of the slide bearing shell take, this can be done with processing equipment, those in the transfer level and in the direction of transfer to the respective guided along stations. For these across the transfer direction or longitudinally moving to the transfer direction tools and processing equipment are available in the frame the invention the possibility of these movements across the trans direction and along the transfer direction synchronously from the for opening and closing the shaping and shaping tools derive intended drive device. For example can the drive device for opening and closing the Tools for shaping and shaping machining a crank mechanism contain. In such a case, this cure can be attached to the crankshaft Beltriebes a cam drive to generate the transverse to the transfer direction and along the transfer direction the tools for machining are connected. Likewise, the drive for the transfer device can be synchronously connected to this crank mechanism.

An embodiment of the invention is described below the drawing explained in more detail. Show it:  

Fig. 1 shows schematically the processing stages of a preferred embodiment of the method according to the invention, starting from a material strip up to the slide bearing shell, which - apart from the sliding surface machining - is finished, wherein Fig. 1 is divided into parts a , b , c ;

Fig. 2 shows an apparatus for performing the method according to claim 1, wherein also Fig. 2 is divided into parts a , b , and c;

Fig. 3 is a schematic overview of the apparatus according to Fig. 2, including the drive means and

Fig. 4 is a diagram for the movement generation and guidance of the tools for machining.

In the example shown, in a seventeen processing stage and one inspection stage, a strip 21 of layered composite material, which is fed to the method, is processed into - apart from the machining of the sliding surfaces - finished semi-cylindrical sliding bearing shells 20 . The band 21 made of layered composite material has the essential layers for the slide bearing shell 20 , namely a carrier layer, which preferably consists of steel and at least one sliding layer made of bearing material. In the example shown, the band 21 made of layered composite material fed to the method or the device has a width which is somewhat greater than the circumferential length of the semi-cylindrical plain bearing shells 20 to be produced . The belt 21 is fed step by step in a direction 26 , which in this exemplary embodiment is the same as the further transfer direction 22 . Each feed step has a length which is somewhat greater than the desired final axial width of the slide bearing shells 20 to be produced .

In stage 1 of the manufacturing process and the device, a strip 23 is cut off at the front end of the band 21 made of layered composite material by prehead cutting, ie a punch-cutting process. The width of this separated strip 23 corresponds to the length of a feed step of the belt 21 made of laminated material. As shown in FIG. 2a, an upper punching and cutting tool 24 , a lower counter-pressing tool 25 and, if necessary, not shown counterholders are provided in stage 1 of the device.

The strip 23 cut off at the front end by the strip 21 made of layered composite material by prehead cutting is checked for usability in stage 1 of the operation. If it turns out during this check that there is a strip that is not suitable for the production of a plain bearing shell, for example due to a faulty cut or due to material defects, this faulty strip is ejected in the form of individual boards. This is indicated in Fig. 1a by the double arrow 29 arranged between stages 1 and 2 .

As shown in FIGS. 1 and 2, the transfer device 27 is further adapted to the individual boards 28 and workpieces in the transfer direction 22 at an equal Festge laid mutual spacing 30 through the Bearbeitungssta functions, namely 2 to transport the stages to 17. The transfer device 27 has two subsections 31 and 32 , of which one subsection 31 extends from the stage 1 station for separating the boards 28 or strips 23 from the material strip 21 to the stage 14 station for forming the boards 28 into semi-cylindrical bearing shells. Moldings 33 extends. In this section 31 , the Transferein device 27 is equipped with the gripping and holding elements 34 over the end regions of the boards 28 . In Fig. 1, these gripping and holding elements 34 are only shown at one end of the boards 28 . The same gripping and holding elements 34 are also provided at the other end of each of the boards 28 . Although this mounting of the boards 28 in a pair of opposing gripping and holding elements 34 does not have to be equipped with excessive precision, this is, however, completely sufficient to remove the boards from the alignment and holding devices (not shown) of each station (stages 3 to 17 ) and place them in the alignment equipment of the next station. The precise, precise alignment is then carried out by means of the alignment devices installed in each stage 3 to 17 .

In the example shown, the stations stage 2 , stage 3 and stage 4 are set up for making circumferential grooves desired in the slide bearing shells. For this purpose, tools 36 for pre-grooving a groove 37 a are mounted in the board 28 in the stage 2 station. In stage 3 , devices 38 for embossing a recessed and widened groove 37 b , that is, for deepening and widening the prepared groove 37 a, are attached. Finally, in the third station, namely stage 4 , devices 40 for reaming the groove 37 c , that is to say widening and re-profiling of the groove 37 b, are provided. Naturally, the devices provided in the stages 2 to 4 for forming longitudinal grooves in the plates 28 or circumferential grooves in the slide bearing shells to be produced can be designed in accordance with any desired shape and number of circumferential grooves and can also be provided in a different arrangement, for example as follows:

In a modification of the example according to FIGS. 1 and 2, devices for machining before the circumferential groove or grooves can be prepared in the stage 2 station, devices for broadening the groove or grooves in the stage 3 station and in the stage 4 station Means for reworking the groove or grooves may be provided by stamping. It is also possible to provide all three stations of stages 2 to 4 with facilities for machining preparation, attachment and reworking of the groove or grooves, for example "room-room-room".

In the example shown, the group of stations of stages 2 to 4, FIG. 1 a, for the production of circumferential grooves of the plain bearing shells to be produced or longitudinal grooves in the plates 28, is followed by a pair of stages 5 and 6 . In this pair of stations, the plates 28 used there by the transfer device 27 are fixed in a precisely aligned position and machined by means of a processing device 42 guided between the two stages 5 and 6 on the opposing axial end faces, for example in the form of broaching. This broaching is carried out on the board 28 located in the station stage 5 , on the front axial end face 43 in the transfer direction 22 and on the board in the station stage 6 be sensitive on the rear axial end face 44 in the transfer direction 22 , so that this broaching when leaving the station of stage 6 on both axial end faces 43 and 44 of the board 28 is done.

At the pair of stages 5 and 6 - as Fig. 1b shows - two stages 7 and 8 for processing the partial surfaces of the slide bearings to be manufactured. In the stage 7 station , the length of the board 28 is trimmed at both ends by means of cutting and punching tools 45 . The remaining length of the board 28 is still somewhat larger than the desired circumferential length of the plain bearing shells 33 to be produced . The waste generated during this pruning is safely and completely removed in the stage 7 station so that it cannot have a disruptive effect in the course of the processing operation. Simultaneously with the trimming of the partial surfaces, the marking of the slide bearing shells to be produced is also stamped into the back surface of the slide bearing moldings 33 in the stage 7 station.

The second stage 8 provided for the processing of the partial areas contains devices 46 for scraping and smoothing the previously cut partial areas using a fine cutting treatment.

At the two stations of level 7 and level 8 for the treatment of the partial area, another pair of stations of level 9 and level 10 follows. In this pair of stations, the end faces 43 and 44 of the plates 28 formed in the pair of stations of stages 5 and 6 are chamfered. For this purpose, a device 47 is provided in a manner similar to that between the pair of stations of stages 5 and 6 , which can be moved transversely to the direction 22 between the stations of stage 9 and stage 10 . This device 47 is designed to chamfer the opposing end faces of the plates 28 previously formed in the pair of stages 5 and 6 . In the same way as in the station pair of stages 5 and 6, the board 28 leaves the stage 11 with chamfering on both axial line surfaces 43 and 44 .

At this pair of stations of stages 9 and 10 is followed by a stage 11 , which is provided for chamfering the partial areas formed in the stations of stages 7 and 8 . For this purpose, this station contains stage 11 devices 48 which can be moved in the transfer direction 22 and thereby produces the desired chamfering on the partial surfaces by fine machining. The thus finished machined boards 28 are then transferred with the Transferein direction of section 31 into the station 12 used for cleaning the board 28 , in which devices 49 , for example brushes and possibly washing devices, are attached for cleaning the boards. The cleaned boards 28 are guided from the last part of section 31 of the transfer device 27 into the station stage 13 . This station is used to bend the board into the semi-cylindrical shape. In order to maintain the previously applied longitudinal groove 41 during this transition into a circumferential groove in its profiling and its dimensioning, that is to say its geometry, during this bending operation, the bending punch 50 provided in the bending station stage 13 is formed with a projection 51 that engages in the groove 41 .

The essentially pre-bent slide bearing sleeve blank 33 is then transported by means of the second section 32 of the transfer device 27 through the further processing stages. In this second section 32 , the transfer device 27 has gripping and holding elements 35 which grip the slide bearing shell molding 33 in the regions of the two partial surfaces and are accordingly advanced further than the gripping and holding elements 34 in the section 31 of the transfer device 27 . In this second section 32 , too, the transfer device 27 is equipped with opposing gripping and holding elements 34 , of which only one gripping and holding element 35 is indicated in FIG. 1c.

The pre-bent semi-cylindrical bearing shell blank 33 is transferred from the bending station stage 13 to the upsetting station stage 14 . In this upsetting station, the finished forming of the machined blanks 28 takes place with adjustment of the final circumferential length, adjustment of the final axial width and formation of the final back contour for the slide bearing shells 20 . As shown in FIG. 2c, a corresponding upsetting tool 53 is provided in the upsetting station stage 14 , which is equipped with lateral molded parts 54 which grip the end faces, upset tools 55 which grip the partial surfaces and a projection 51 which engages in the groove 41 .

The semi-cylindrical bearing shell moldings 33 are transferred from the upsetting station stage 14 into punching and punching stations of the stages 15 and 16 . These punching and punching stations of stages 15 and 16 can optionally be equipped with punching tools 56 for round holes ( 41 ) or punching tools 57 for elongated holes ( 39 ). If only one type of hole is to be provided in the slide bearing shell 33 , one or the other of these two stations of the stages 15 and 16 can be unoccupied.

Finally, the plain bearing shells 33 are transferred from the second punching and punching station of stage 16 to the stage 17 station. There, by means of appropriate cutting and bending tools 58, locking elements 59 are formed in the plain bearing shell molding 33 .

The slide bearing shells 20 leave the last station stage 17 in a finished state apart from the processing of the sliding surfaces, any additional coatings to be provided, which are to be applied as an overlay or running-in layer by galvanic means or as an anti-corrosion layer on all surfaces of the sliding bearing shell.

As shown in FIG. 2, the devices provided for all stations of stages 1 to 17 are mounted on a tool base plate 61 and a head plate 62 . The tool base plate is attached by means of a clamping plate 63 on a press table 64 , while the head plate 62 is attached to the plunger 66 of the machine via an intermediate plate 65 . In this way, all facilities of the stages of stages 1 to 17 are operated simultaneously by moving the plunger 66 downwards and opened by lifting the plunger 66 . When the plunger 66 is raised, that is to say when the device is open, the boards 28 and the work pieces 33 are each transported by one step, ie by the length 30, from one station to the next by means of the transfer device 27 . After passing through the stations 2 to 17 a formed in station 1, usable strip is thus 23 from the band of material 21 to a - converted finished plain bearing shell 20 - apart from the processing of the sliding surface. The slide bearing shell 20 is - as shown in Fig. 1, part c - equipped with the desired circumferential groove 37 and possibly desired round holes 41 and elongated holes 39 . The back surface of the slide bearing shell 20 as well as the axial end faces and the partial surfaces are brought into the final shape by the compression molding step.

As can be seen from FIG. 3, for the opening and closing of the shaping and shaping tools and the cutting tool of stage 1, the head plate 62 carrying these tools is connected via the intermediate plate 65 to a plunger 66 , which itself again by means of two or more links 79 is articulated to a crankshaft 67 mounted in the upper part of the device. The crankshaft 67 is driven by a drive shaft 80 to rotary motion or back and forth tilting movement, a cam gear 68 being inserted between the crankshaft 67 and the drive shaft 80 , of which a drive linkage 69 for driving the transfer device 27 and a Drive linkage 70 are derived. The drive linkage 70 leads via an intermediate gear 81 to a tilting shaft 71 which extends along the tool base plate 61 above the platen 63 and the press table 64 and the row of all processing stations stage 1 to 17 . This tilting shaft 71 is formed at each station, but at least at those stations that contain tools for machining, each with a crank part 72 ( FIG. 4) and is driven synchronously to the crankshaft 67 by the intermediate gear 81 for back and forth tilting movement . Above the crank part 72 , a fork-shaped rocker arm 73 is placed in those stations which contain tools 76 to be machined transversely to the transfer direction 22 , which pivot pin 74 is pivotally mounted above its fork part. The rocker arm 73 is connected at its end opposite the fork part via a pivot pin 75 to the tool 76 which can be moved back and forth in the tool guide 77 in the sense of the double arrow. In this way, a reciprocating movement of the tool 76 takes place transversely to the transfer direction 22 and in synchronism with the movement of the crankshaft 67 and thus of the plunger 66 carrying the tools for shaping and shaping machining.

If tools for machining are to be moved in the transfer plane parallel to the transfer direction, this can be done via a deflection gear 78 to be attached to the tilting shaft 71 . Thus, the movement of the tools to be machined parallel to the transfer direction for machining is synchronized with the movement of the plunger 66 and the tools carried by it for shaping and shaping processing. As a modification to the exemplary embodiment shown, a material strip could also be supplied which has a slightly larger width than the desired axial width of the slide bearing shells 20 to be produced . This material band would then be introduced at right angles to the transfer direction 22 into the stage 1 station and cut in the stage 1 cutting station in a cut parallel to the transfer direction 22 to the strips 23 , the length of which is somewhat greater than the desired circumferential length of the slide bearing shell 20 , that is to say in the dimensions of the strip 23 according to FIG. 1 part a corresponds.
