Abstract

The invention relates to the processing of metals by pressure, in particular, to die tooling for processing sheet material. The purpose of the invention is the expansion of technological capabilities by ensuring the wiring of the saw teeth. The device contains sliders / П / 9, strips 5 with wedges 11 and shaft 23 with lever 24. П 9 consists of fixing part / ФЧ / 29 and divorcing part / RF / 31. On ФФ 29 there is a tooth for fixing material 35 with pre-notched teeth, and bevel teeth for wiring on RF 31. The FC 29 acts relative to the RF 31 and is spring-loaded by the spring 34. When the top plate moves downwards, it acts on the lever 24, turns the shaft 23, moves the strips 5. The wedge 11 is reduced to P 9.

PIP,

Figure 1 shows a stamp with a device for fixing the wiring, general view; in FIG. 2, a stamp without a top plate, top view; on fig.Z - slider; figure 4 - section aa in fig.Z.

A device for fixing and setting the saw teeth is installed in a die containing the bottom plate 1 with the die 2. On both sides of the axis 3 of the material is fixed; ; pillars 4 arranged in pairs on both sides of the plate 1. In each pair of pillars 4, a bar 5 is mounted so that it can move in the horizontal plane. At the end of the bar 5 there is a flange 6. On the bracket 5 between one of the pillars 4 and the flange 6 there is a spring 7. On the bottom plate of the 1 stamp, there are directional B slats B, located symmetrically; but relative to the axis 3 of the feed material ..

A slider 9 is mounted in each guide bar 8. At the end of the slider 9, a roller 10 is mounted, which interacts with a wedge 11 fixed on the strap 5 between the uprights 4. The slider 9 is spring-loaded in the direction of the slats 5 by springs 12d.

On the top plate 13 of the punch are fixed punches 14 and a clamp 15 with an elastic element 16. In the upper plate 13 a glass 17 is screwed (threaded bushing) fixed by a nut 18.. In the cavity of glass 17 closed by a washer screwed into it 19 a flange 21. In the bottom of the glass 17, a hole is made for the rod 20 with water. In the cavity cavity 17 between the washer 19 and the end of the flange 21 of the rod 20 there is a spring 22. On the bottom plate 1 a shaft 23 is mounted, on which one end of the gland 24 is fixed, which interacts with another the end with the rod 20. At each of the ends of the shaft 23 JCOMM is fixed at one end pbwar 25. Its

The free end of each lever 25 is pivotally connected to lever 26. Each lever 26 is made of two parts connected to each other by a nut 27 fixed on the lever 2: 6 by nuts 28, each of which is screwed onto one of the parts of lever 26.

Each slider 9 is made of an integral part of the fixing part 29 with the teeth 30 and the divorcing part 31 with the teeth 32. They have inclined surfaces 33 with an alternating direction of inclination.

Part 29 is relative to part 31 and is spring loaded 34.

The material to be processed is indicated by the position 35.

The device works as follows, o

The material 35 is fed into the rail of the bar 8. When the upper plate 13 moves down, the rod 20 acts on the tip of the lever 24, which turns the shaft 23. The shaft 23 rotates the levers 25, which through the levers 26 drive the bar 5, compressing the spring 7. The wedge 11 acts on the rollers 10, which move the sliders 9 in the direction perpendicular to the movement of the material 35, while the springs 34 and 12 are compressed, the part 29 of the sliders 9 with its teeth 30 acts on the material 35 with notched teeth and performs its fixation on the working position of the stamp and

preset position I

After this part 31 of the slider 9,

I act by the teeth 32 on the teeth of the material, distributing them. The force of the pin 22 must be greater than the effort necessary for the placement of the teeth. With the further progress of the upper seal 13 of the punch down, the rod 20 is transferred upward, compressing the spring 22, and the punch 14 cuts down the next one (teeth on the edge of the workpiece.) During the course of the upper plate 13, the punch 14 goes out of interaction with the material 35 and the die 2, the rod 20 moves down under the action of the spring 22, then leaves the engagement with the end of the lever 24. Simultaneously with the movement of the rod 20 up, the bars 5 under the action of 7 move to the right and turn through the levers 25 and 26 the shaft 23 o The shaft 23 rotates the lever 24. When the rails move 5 right roll ki

 10 slides on wedge m 11, and crawl-. ki 9 under the influence of spring 12 I move from material 35 and release it. Then the cycle of operation is repeated.

Adjustment of the moment of clamping of the material 35 by the sliders 9 and the magnitude of the tooth wiring angle (force from the impact on the material) is carried out with screwing and screwing the cup 17 and changing the length of the levers 26 using nuts 27.
