SU1493358A1 - Die for working sheet material - Google Patents

Abstract

The invention relates to the processing of metals by pressure, in particular, to dies for processing sheet material. The purpose of the invention is to improve the quality of products. The stamp contains plates (P) 9 and 13. A wedge 14 is mounted on P 9, and a block (B) with tools 1 and 2 for the production of expanded metal mesh is installed on P 13. An adjustable travel stop 16 is placed on P13. The latter is spring-loaded with a spring 17. Tape 18 is fed to the working position. During the course of P 9 down wedge 14 move B to the feed step. Thereafter, tools 1 and 2 produce a cut-out. When lifting P 9 spring 17 moves B to its original position. Together with it, the belt 18 moves beyond the protrusions and the axes of the cuts. Then the cycle repeats. 2 hp f-ly, 2 ill.

The invention relates to the processing of metals by pressure, in particular to dies for processing sheet material, mainly for the manufacture of

the unit is moved by the action of the spring 17 and moves the belt 18 over the cut and drawn sections.

With the next working stroke, all actions are repeated when the block is moved in the transverse direction to a different position.

The implementation of the invention improves the quality of products by providing more accurate and high quality material supply.

no expanded mesh from tape.

The purpose of the invention is to improve the quality of products.

Figure 1 shows the stamp, section; figure 2 - section aa in figure 1. Yu

The stamp contains as working tools the upper 1 and lower 2 knives fixed in the respective Holders 3 and 4, which by means of the guide columns 5 are enclosed in 15 single unit, mounted on the integral part 6 of the holder 4 with the ability to move in the plane perpendicular pressure axis.

The stamp also contains a mechanism for moving the tools 1 and 2, including stops 7, a wedge 8, articulated with the movable plate 9 of the stamp, cams 10, spring-loaded to part 6 (springs not shown), and a sub- material , and in the plane, a perpendicular-spring clamp 11, for which the pressure axis of the die is stamped, the formula of the invention

1. A stamp for processing sheet material comprising movable and n movable plates with work tools each installed in a respective holder and associated guide elements, a mechanism for moving at least one tool in a direction perpendicular to the direction of movement

in part 6 there are holes 12. The unit is mounted on a fixed plate 13.

In addition, the stamp contains a means for moving the block, made in the form of wedges 14 mounted on the plate 13, projections 15 made on the part 6, limiter 16 having the possibility of adjustment, and springs 17

The stamp for the processing of sheet material works the next (named.

The belt 18 is fed to the machining position. During the course of the plate 9 down, the wedge 14 acts on the projections 15 and moves the block with the tools 1 and 2 by the pitch, compressing the spring 17. The pitch is determined by adjusting the stopper 16.

Upon further movement of the plate 9, one of the wedges 8 enters between the cam 10 and part 6. The cam 10 abuts against the stopper 7, and part 6 moves with the unit across the axle of the belt 18. The other wedge 8 finds the other cam 10 and deviates to the side . Part 6 is fixed relative to the plate 13 with the clamp 11, the plate 9 presses the holder 3 and a notch occurs — the knives 1 and 2 pull out

During the reverse course of the plate 9, the wedge 14 comes out of contact with the protrusion 15 and

the unit under the action of the spring 17 is moved and moves the belt 18 over the notched and drawn sections.

During the next working stroke, all actions are repeated when the block is moved in the transverse direction to another position.

The implementation of the invention allows to improve the quality of products by providing more accurate and high-quality material supply.
