Abstract

The invention relates to the processing of metals by pressure and can be used for precipitation of hollow billets in large-scale and mass production. The purpose of the invention is to increase the reliability of work and the splitting of technological capabilities. The stamp has a die and a movable punch. After precipitation of the workpiece, the punch moved by the buffer pushes the part by means of pushers from the die. The resulting part is spring-raised by the punch above the level of the pullers, the sliders, which are fed under the part. When the ram moves upward, the punch goes down through the rolling pin, the lever and the pusher and the part is removed from the punch. 1 il.

Description

The invention relates to the processing of metals by pressure and can be used to precipitate hollow billets.

The purpose of the invention is to increase the reliability of work and the expansion of technological capabilities.

The drawing shows a stamp cut.

The stamp consists of the bottom plate 1 of the holder 2 with the matrix 3 fixed in it, the movable punch 4. The punch is driven from buffer 5. spring 6 and the press ram through pushers 7 and 8. lever 9. mounted on axle 10 and pressed with spring 11, rolling pins 12, an emphasis 13, which is pressed by a spring 14. the force of which is regulated by a stopper 15.

Along the sleeve guides 2, the sliders 16 are asymmetrically located, driven by a spring 17 and a wedge 18 fixed in the upper plate 19. A die 20 and a rolling pin 21 are attached to the upper plate 19.

The stamp works as follows.

As the slider moves down the wedge 18, the sliders 16 are retracted from the punch 4. The die 20 approaches the punch 4, and the workpiece 22 settles.

During the course of the slide up the buffer 5 through the pushers 7 and 8 pushes the part together with the punch 4 from the matrix 3 to a height h equal to the height of the working part of the matrix, and the spring 6 raises the punch above the level of the matrix 3 to a height greater than hi. The sliders 16 by the springs 17 are applied to the punch 4, the stop 13 is for the top of the annular recess and there is no rolling pin 12 along the guide 21 upwards. The lever 9 associated with the rolling pin rotates around axis 10 and through the pusher 8 tons there is no punch 4 down. The workpiece during the downward movement of the punch 4 rests on the slider pullers 16 brought under it, is removed from the punch 4 and is blown off by air from the working zone. When reaching the force exceeding the force of the spring 14, adjustable by the plug 15, the stop 13 moves to the right and the rolling pin 12 under
