Abstract

The invention relates to the field of processing materials by pressure, in particular to the structures of auxiliary mechanisms of cutting and sequential dies. The purpose of the invention is to increase reliability and simplify the design. The device contains a spring-loaded diverter 11, a spring-loaded clamp 15, located in the horizontal plane. The retainer is L-shaped and is installed at a distance from the stop plane of the ejector 11 less than the length of the cut piece 18. The ejector plays the role of an abutment. When the material is fed, the cut piece moves to the stop head of the L-shaped latch 15, compresses the spring 16, releases the resetter 11, which, by the action of the spring 12, resets the cut piece 18, after which it takes up the stop position. 4 il.

The invention relates to the processing of materials by pressure, in particular to the structures of auxiliary mechanisms of cutting and sequential dies.

The purpose of the invention is to increase reliability and simplify the design.

FIG. 1 shows a stamp, a general view of FIG. 2, a plan of the lower part of the stamp in the closed position; in fig. 3 shows section A-A in FIG. one; on figa - plan of the lower part of the stamp in the initial position. ,

The stamp contains the bottom plate 1, on which the dies 2 with the guide bars 3 and 4 are installed, the pusher plate 5 with the bars 6 and 7 and the buffer 8, the plate 9 with the housing 10 fixed on it. Also, the role of the stop is spring loaded 12 in the direction perpendicular to the movement of the material being stamped 13, plug 14, adjusting the force of spring 12, L-shaped clamp 15 with the working end and stop head, spring loaded 16, plug 17 regulating the force springs 16. On the side surface syvatel 11 by the L-shaped retainer 15 vtolnen ledge under the working end retainer.

The stop head of the L-shaped retainer 15 is at a distance L from the stop plane B of the ejector 11, less than the length of the piece to be cut 18 for ensuring the reset of the part. On the top plate of the stamp 19 is fixed, the holder 20, on which the wedge 21 is installed, the cutting punch 22, the piercing punches 23, the strap 24 with buffer 25.

The stamp works as follows.

The material being stamped 13 is fed as far as the stop B of the plane B, the ejector 11, which plays the role of the stop, along the guide bars 3, 4, 6 and 7. When pressing down, the material 13 is pressed first by the bar 24, and then the cutting punch 22 cuts off detail 18. The piercing punches 23 cut holes in the material 13, and a wedge 21 removes the diverter 11. The diverter 11 is fixed in the retracted state by the working end of the fixer 15 with the help of a step made on the side of the diverter

enabling further movement of the cut piece 18 to the L-shaped latch 15. During a press up stroke, the cut piece 18 is moved upward by means of the buffer 8 until it coincides with the level of the material 13, which is removed from the punch 23 by the buffer 25.

When the material 13 is fed, the cut piece 18 moves to the stop head of the L-shaped latch 15, compresses the spring 16, releases the resetter 11, which, by the action of the spring 12, resets the cut piece 18, after which it takes up the stop position, then the cycle repeats.
