RU1801685C - Device for manufacturing parts from strips - Google Patents

Abstract

Usage: in automatic sheet metal stamping devices. The inventive device includes a stamp with punches 5 for drawing, dies 6 for cutting, punch dies 10. The latter are installed on the bottom kick 11 and pushers 13 are installed on channels 12 for moving parts into the transport chain 18. Pushers 13 tc with rods 7, and they get the working movement from the springs 16. During the working stroke, the elongated parts 24 fall into the channels 12, and during the reverse stroke the pushers 13, under the action of the springs 16, move the parts 24 into the chain 18. 2 c.p. f-ly. 4 ill.

Description

The device relates to mechanical engineering, forging equipment, in particular to devices for sheet stamping.

The purpose of the invention is the expansion of technological capabilities through the manufacture of parts with a spatial configuration.

In FIG. 1 shows a general diagram of the device, a top view: in FIG. 2 - node I in FIG. 1; in Fig.Z - section aa of Fig.2: in Fig.4 - section bB of Fig.Z.

A device for cutting parts from strip material is mounted on a bed

I and includes a press 2 with a stamp 3, in the punch holder 4 of which the exhaust punches 5 are fixed: die-cutting dies 6 and rods 7, which have grooves 8 and 9. The exhaust die 10 is simultaneously a die-cutting punch and is installed in the plate 11. On the bottom surface of the plate

II, channels 12 are made in which the pushers 13 are placed. They have spring-loaded stops 14. The rods 7 pass through the holes 15 made in the pusher 13. The spring 16 presses the pusher 13 against the rods 7. The strip 17 is located at an angle to the conveyor, made in the form chain 18, the upper links of which 19 and 20 form a plane 21, coinciding with the lower plane of the pusher 13. The chain 18 has stops 22 and slots 23 for parts 24. The cross section of the matrices 6 on the working section of the hood 25 is made smaller than in section 26, a failure hole it. A device for manufacturing parts from strip material is included in a rotor-conveyor line including process rotors 27 and 28, and tension sprockets 29 and 30.

The device operates as follows.

When the punch holder 4 moves down, there is a sequential cutting and drawing of parts 24, which fall on the plane 21. When the punch moves (L

the holder 4 is up, the stop 14, under the influence of the spring 16, moves to the left and enters the groove 9. In this case, the parts 24 move along the plane 21 to the left and meet the stops 22, fall into the slots 23 and are removed from the zone of the stamp 3. At the beginning of the stroke, the punch holder 4 down, the rods 7, in contact with the holes 15 of the pusher 13, move it to the right, compressing the spring 16. In the future, the cycle repeats.

Compared with the prototype, the proposed device allows to expand technological capabilities due to the manufacture of parts with a spatial configuration.

Claims (3)

SUMMARY OF THE INVENTION 1. A device for the manufacture of parts from a strip material comprising a stamp, in the upper part of which are punches in the lower part of the matrix, and a conveyor with slots for accommodating blanks, characterized in that, in order to expand technological capabilities by manufacturing parts with 0 5 0 spatial configuration, the conveyor slots are offset relative to the matrix holes, the axes passing through the centers of the slots and holes are parallel to each other, channels for moving the workpieces in communication with the conveyor slots are made under the matrix holes in the bottom of the stamp and the device is equipped with means for moving the workpieces into the slots conveyor in the form of spring-loaded pushers, each of which is located in the corresponding channel, and a wedge mechanism located in the upper part of the stamp with the possibility of the interacting with the pushers. 2. The device according to claim 1, with the proviso that the distance between the channels in a direction parallel to the axis of the conveyor is equal to the distance between the slots of the conveyor. 3. The device according to claim 1, with the exception that the cross-section of the matrix hole at the exit is made larger than at the entrance. . Phage / 5th FIG. 4 22 12
