Description

The invention relates to the cold processing of metals by pressure and can be used for stamping parts of strip and strip material.

The purpose of the invention is to increase the reliability of operation.

1 schematically shows the proposed device for stamping parts from a strip and tape material, a section; figure 2 is a view of And figure 1; in FIG. 3, view B in FIG. in fig. 4, view B in FIG. figure 5 - section GG in Fig, 4.

The device contains a compound stamp, the material feed mechanism

the working area of the stamp (not shown), the pusher of parts from the material and the mechanism for moving parts, the Compound stamp contains a stationary plate 1, a movable plate 2 ,. carrier punch 3 for cutting parts 4 out of material 5, strip or tape, matrix 6 for cutting out the outer contour of a part, ejector 7, fitted in matrix 6, washer R movably mounted in plate 2, 9 9 mounted on plate 2, shank 10, screwed into key 9, spring 11 located between cover 9 and. washer 3. Washer 8 through 111mt11-- you 12 interacts with the ejector 7.

Pa plate 1 is fixed to the punch 13, N. and which is movably mounted puller 14, spring-loaded gasket-15 from an elastic material. The puller 14 is fastened in plate 1 with screws 16. The dial of the parts made of material includes a housing 17 fixed to the plate 2, a push rod G8 mounted in the housing 17 so that it can be rotated and moved in the vertical direction. The pusher 18 is spring-loaded spring 19. On the plate 1 is fixed plate-stripper 20, located under the plane of the material supply 5. In the plate-stripper 20, a hole 21 is made for the passage of parts 4 and a current ring 18. On the body 17 a cam 22 is fixed, made in the form of a triangular prism , and on the pusher 18 is fixed a cam pusher 23 made in the form of a response triangular prism. On the pusher 23 is fixed handle 24.

The mechanism for moving parts comprises an additional plate 25 for moving parts, mounted on plate 1, a rotor 26 carrying a rotary disk.27. The disk 27 is fixed grippers 28 for parts located around the circumference. Tool block ro

The rotary machine (not shown) contains a base 29, a housing 30 with a spring-loaded spring 31 and a safety device 32j of the ejector 33 of the parts 34.

The device works as follows.

The cut piece 4 in the die is pressed into the material, strip or tape and the feed mechanism feeds the material into the feeding step. The part 4 in the material 5 is placed with a pusher 18. During the course of the plate 2, the pusher 18 pushes the part 4 out of the material 5 and through the hole 21 in the plate-detach-. ifflKe 20 moves to the plate 25. When the rotor 26 rotates with the disk 27, the grippers 2B move parts from under
