Abstract

The invention relates to the cold working of metals by pressure and can be used to process strip and strip material. The purpose of the invention is the expansion of technological capabilities by processing parts of various sizes and configurations. The strip or strip is fed to the treatment area up to the stops fixed to the fixed plate. Stepper stops mounted on a fixed plate in front of the stops form grooves on the sides of the material, and the cutting punches cut down the parts from the material. Cutting punches are mounted on a movable plate and are located between the stops and stepping knives. The material moves to the feeding step by the feeding carriage carrying the gripping bodies. Gripping bodies are made in the form of spring-loaded pillows, located symmetrically with respect to the feed axis and interact with the grooves on the lateral sides of the material. When the feed carriage is idled, the material is prevented from moving by spring-loaded brake slide mounted on a fixed plate. A hinged dog with a figured end is also mounted on the feeding carriage. 4 il.

The invention relates to the cold working of metals by pressure and can be used to process strip and strip material.

The aim of the invention is the expansion of technological capabilities by stamping parts from a material with a large width.

FIG. 1 shows a device for processing strip and strip material; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. 2

The device contains a feed carriage 2 mounted on the bottom plate 1, on which roller 3 is mounted, which interacts with a wedge 4 mounted on the top plate 5. The feed carriage 2 is made in the form of a traverse 6 connected to two spring-loaded rods 7 carrying they are spring-loaded half-poles made in the form of feeding dogs 8. In the groove of the traverse 6, a spring-loaded dog 9 is placed at one end between the matrix 10 and the puller 11, and at the other end of the dog 9 there is a hook; cerned corresponds to the contour of the end parts of harvested punches 12 and the outer surface is at an acute angle to the direction of feed of the material. A spring-loaded L-shaped brake slider 13 is mounted on the puller 11 from its end, and on its L-shaped ends 14 are wedge surfaces identical to the working surface of the stepping knives 15 fixed in the punch holder 16. Permanent stops 17 are placed between the matrix 10 and the puller 11.

The device works as follows.

The strip 18 is fed as far as the stop 17, the upper plate 5 of the stamp is lowered down, moving the feed carriage 2 under the action of the wedge 4 in the feed direction of the material without the strip, then the right punch 12 cuts the part, and the stepping knives 15 make grooves in the strip 18. After that 5 is lifted along with the wedge 4, the punches 12 and the step knives 15, the wedge 4 releases the carriage 2, the yoke 6 with the rods 7 moves towards the feed of the strip under the action of springs. The retention of the strip at the moment of returning the crosshead 6 with the thrusts 7 is carried out by any known method (not shown). At the end of the stroke, the yoke 6 with tami 7 spring-loaded dogs 8 stop against the grooves cut in the strip by the stepping knives 15, and drop into them, seizing the strip. During the second stroke of the press, the strip 18 is automatically fed into the stamp with the help of dogs 8, and after the third stroke of the press, the spring-loaded dog 9 comes into operation, which, when fed into the strip, is repelled by the end of the piece cut off by the middle punch 12. Later, the L-shaped sliders 13 come into operation. The half-sleeves 13, with their ends 14, hold the waste and the strip 18 from moving them back into the stamp. Spring-loaded dog 9 (after the third move) with each stroke of the stamp captures with its hook the end of the piece chopped off by the middle punch 12 and moves the strip 18 along with the dogs 8, which enter the work later, into the stamp. At the end of the processing of the strip 18, its dimensions change in width to the smaller side (after the end of cutting down by the right punch) and the dog 9 feeds the axle

The strip and the waste with the dogs 8. After the end of the strip treatment, a new one is established and the cycle repeats.
