The invention relates to the processing of metals by pressure, in particular to devices for forming roller-stub chains. A device for manufacturing plates of roller-sleeve chains, containing working tools mounted in a housing with a profiling surface on each of them, a mechanism for feeding blanks, is known. A disadvantage of the known device is the low quality of the finished products. The purpose of the invention is to improve the quality of finished products. The goal is achieved by the fact that a device for manufacturing plates of roller-bushing chains, containing working tools mounted in a housing with a profiling surface on each of them and a feed mechanism for workpieces, are mounted on the housing from the opposite side of the workpiece feed mechanics, a support mechanism with a drive and a stop , moreover, the support mechanism is made in the form of a U-shaped, spring-loaded with respect to the stop, a guide, and the drive of the support mechanism is made in the form of interacting with the U-arm wedge guide, while the working tools are made in the form of plates with shaping and calibrating, spring-loaded inserts placed in one of them. FIG. I shows the device, a longitudinal section; in fig. 2 - the same, cross section; in fig. 3 - the same, top view; in fig. 4 is a section A-A in FIG. 3. A device for manufacturing plates of roller-sleeve chains comprises a body 1, to which a click 2 and working tools 3 and 4 are attached, the working tools being made in the form of plates with a profiling surface, and one of the plates is made with an insert 5 with a shaping surface and with an insert 6 with the calibrating surface. The insert 6 interacts with the pushers 7 and the springs 8. A support 9 and a support mechanism are fixed to the housing from the side opposite to the workpiece feeding mechanism (not shown). The support mechanism is made in the form of a П-о of a different guide 10. In the slot, the guide 10 and the clamp 11 are spring-loaded relative to the stop 9. The drive of the support mechanism is designed as a wedge supporting mechanism interacting with the guide. Reference numerals 12 and 13 denote a molded plate, respectively, not yet cut from a strip blank, and a sliced plate. The device works as follows. In the initial state, the insert 6 with the calibrating surface under the action of the pushers 7 and the springs 8 occupies the extreme upper position, while its upper cavity is located higher than the most protruding part of the working tool 4. The initial blank (strip or ribbon) in the “edge serves into the workspace at the required step. Since the wedge 2 with the working tool 3 occupies the extreme upper position, the support mechanism is in the inoperative position, the workpiece can freely move both in the working space and in the gap between the clamp 11 and the guide mechanism guide 10. Press housing 1 is switched on and with working tool 3 starts to go down. While initially a wedge 2 sets in motion the guide 10 of the support mechanism. The guide locks the working cavity of the pressing elements. The end of the strip (tape) or a previously stamped part 13, pressed against it by a clamp 11, is separated from the original preform and remains clamped. The working cavity is in this case locked in the feed direction. Upon further movement of the wedge, the guide 10 remains stationary, and the most prominent parts of the working tool 3 and the insert 5 begin to penetrate into the metal of the workpiece, while the printed part 12 initially moves down as a whole, and then begins to complete the design of its contour. At this final moment of the punching process, the flow of metal from the working cavity in the feed direction is difficult due to the very small gap between the opposing most prominent parts of the working tools and the insert (the bridge is formed), and in all other directions the material from the working cavity does not flow maybe shaping occurs almost in a closed volume. At the same time, between the working tools 3 and the calibrating insert 5, which is lowered down under the action of the workpiece, the initial workpiece is calibrated in width. The latter is necessary, since in the working cavity before shaping the amount of metal must be strictly defined. At the end of the forming part. &Quot; 13 " 13, the body 1 with the wedge and the working tool begins to lift upwards, the spring guide 10 returns to its original position, releasing the part 13, which falls down the slide, away from the device. The molded part 12, connected by a jumper to the band blank, is also released under the action of the spring-loaded pushers 7 and the calibrating insert 5 of the working tool 4, raised by the amount required for the subsequent feeding of the workpiece. After that, the cycle repeats. Forming plates occurs in the proposed device without advance. since it is kept in a closed volume, and harmful negative backing is easily eliminated, it is easier to get ahead of time. The resulting details of the automation, as compared with the base, will provide more accurate dimensions, and the whole process. Tom.
