Abstract

STAMP OF SEQUENTIAL ACTION FOR TREATMENT OF STRIP AND BELT MATERIALS, containing the upper and lower plates with working tools and ejectors installed in them, a wedge fixed in the upper plate, a slider installed in the lower part with the ability to interact with a wedge, gate, shifter . Manufactured from one working position to another and rigidly connected with a slider, and a node that delays the ejector, made in the form of a fixing bar, installed with the possibility of interaction with the ejector. Mounted in the lower part, characterized in that, in order to reduce the dimensions of the punch, the wedge is made with an additional working surface, and the bar is installed in the slider so that it can interact with the additional working surface of the wedge and move in a direction parallel to the movement of the slider.

Description

The invention of OTIIOCHTCH to metal forming, in particular for the production of sheet metal parts. The closest to the proposed one for the combination of the supreme signs and the effect achieved is a sequential stamp for processing strip and tape material containing upper and lower plates with working tools and ejectors installed in them, a wedge fixed in the upper plate, but a slip mounted in the lower part with the possibility of interaction with a wedge, a gate, rigidly connected with a slide, and a knot that delays the ejector and is made in the form of a fixing bar, installed with ozhnostyu reacting with ejectors, rasnolozhennymi in the lower part 1. The disadvantage of this die are its large size. The purpose of the invention is to reduce the dimensions of the stamp. The goal is achieved by the fact that in a sequential stamp for processing strip and tape material containing upper and lower plates with working tools and ejectors installed in them, a wedge fixed in the upper plate, a slider installed in the lower part with the possibility of interaction with a wedge, a spindle, moving the semifinished product from one working position to another and rigidly connected to the polzushkoi, and a node that delays the ejector and is made in the form of a fixing bar, installed with of the interaction with ejectors disposed .mi at the bottom, the wedge is further working noverhnostyu, nlanka installed in polzushke to cooperate with additional labor and noverhnostyu wedge movable in a direction parallel to the movement polzuschki. FIG. 1 shows the proposed stamp in a section perpendicular to the feed direction of the material being processed; in fig. 2 is a section A-A in FIG. one; in fig. 3 - working tools of the transition; pas figs. 4 - the part is ready; on fit. 5 is a section BB in FIG. one; in fig. 6 shows a section B-B in FIG. one; in fig. 7 is a cross-section of the FIG. 1. The stamp contains the top plate 1, the punches 2-6, installed in this plate, the ejector 7, spring-loaded 8, the wedge 9 with an additional working surface formed by the pads 10 On the bottom plate 11 are installed the ejector 12, matrix 13-15, the punch 16 and guides 17. A slide 18 is mounted in the guide 17. Gate 18 is rigidly attached to the slide 18. The fixing strip 20 is mounted in the slide 18 with the possibility of moving in the direction parallel to the displacement of the latter and interacting with ejectors located in the lower asti. The ball retainer 21 is installed in the bottom plate 11 with the ability to interact with the bar 20. The ejectors 22 and 23 installed in the bottom plate are spring-loaded respectively with springs 24 and 25. The stamp works in the following manner. The material being processed is fed to the DD-D level (the material feed mechanism is not shown), where after molding (transition I), which is carried out by the punch 2, the material is transferred in one step (transition II, for structural considerations, idle) to the next position, on which (transition III), when the press crawls down, the punch 3 on the die 13 cuts the blank. At the same time using the wedge 9 slider 18 moves the gate 19 to the extreme right position. When the lining 10 interacts with the portions of the lath 20, the latter is intermixed, the ejector 22 stops and is fixed by the latch 21. With the further movement of the press ram down, the punch 3 pushes the workpiece through the die 13 into the auxiliary (left) hole in the gate 19, then using the punch 16 At the end of the press ram downwardly, the punch 4 punches the hole in the workpiece, and the resulting waste through the holes in the punch 16 and the bottom plate 11 under the action of its own weight is removed to the outside. During the upward movement of the press ram, the punches 3 and 4 exit the gate 19, and the workpiece under the action of the ejector 7 interacting with the spring 8 remains in the die 13; further, under the action of the wedge 9, the slider 18 with the clamp 19 moves to the jaw H to the extreme left position, after which the bar 20, which interacts in sections 6 with the grommets W, is also moved to the leftmost position to the mandrel h, where it is fixed by the latch 21. At the same time the ejector 22 is released and under the action of the spring 24 moves up, removes the workpiece from the punch 16, pushing it into the middle hole of the gate 19. At the next stroke of the press slide down, the gate 19, moving to step H, transfers the workpiece to the next transition (transition IV), where with schyu cone matrix 15 and the punch 5 otformovka final manufactured article. At this time, the ejector 23 is fixed in the lower position by the nlank 22 similarly to the ejector 23. Next, the press slide head rises, and, in accordance with the above, the gate 19 moves to the left by step H, and the bar 20 - by step h. At the same time, the ejector 23 is released and, under the action of the spring 25, pushes the product into the right opening of the gate 19, from where the next stroke of the press slide

down the product is removed by the punch 6 (transition Y).

At the same time, three blanks at the III, IV, and V junctions are processed.

The proposed implementation of the stamp allows reducing its dimensions.
