Description

 The invention relates to the cold processing of metals by pressure and can be used to feed piece blanks into a treatment zone, in particular a press.

The purpose of the invention is the expansion of technological capabilities by submitting blanks to two working positions.

FIG. 1 shows the proposed device; in fig. 2 is a view A of FIG. 1i in FIG. 3 is a view of B in FIG.

A device for feeding piece blanks into a treatment zone contains a mechanism 1 for horizontal movement of blanks (not shown), a non-supporting bracket 2 plate 3 hingedly attached to the bracket 2 by means of an axis 4, an extension spring 5 connecting the bracket 2 and the plate 3 between each other. On the lower side of the plate are fixed plate springs 6, forming a plate with a 3 gripping body. The bracket 2 with an axis 7 is hinged on a bar 8, which interacts with a cam 9 mounted on a fixed plate 10. A spring-loaded stop 12 and a ha 13 are mounted on the upper movable plate 11 13. An axle 14 is hinged on the top 13 by means of an axis 14 15, spring loaded 16.

Plate 3 is made in the form of a fork. In the lower part of the plate 3 (protrusions forming the plug), permanent magnets 17 are fixed. The plank 8 and the plate 3 are interconnected by a spring 18. A stamp 19 is mounted on the plate 10.

The device works as follows.

Mechanism 1 drives bracket 2 with bar 8 and plate

3. The workpiece is caught by the magnets 17. When the bracket 2 is moved, the workpiece enters the groove, - formed by the leaf spring 6 and the bottom side of the plate 3. Then the bar B

interacts with the cam 9 and rotates on the axis 7. With further movement of the bracket 2, the bar 8 leaves the interaction with cam 9, which passes through

the stop of the gshank 8 and returns to the initial position, turning on the axis 7, under the action of the spring 18. The plate 3 under the action of the spring-loaded stop 12 when the upper plate 11 moves down turns on the axis 4 and lays the workpiece on the first position of the stamp 19.

After processing the workpiece, plate 3 moves it to position II

stamp 19. When this strap 8 interacts with the cam 9 and fixes the workpiece relative to the stamp 19.

After processing at position II, plate 11 moves upwards and the dog 15, interacting with the bar 8, rotates the latter., Freeing it from interacting with the cam 9. After that, the bracket 2 with the bar 8 and plate 3 returns to its original position. The cycle of operation is repeated.

The economic effect from the use of the invention will be 8.6 thousand.
