SU1205974A1 - Arrangement for removing parts from a die - Google Patents

Description

This invention relates to the automation of stamping production and can be used to remove parts from a die.

The purpose of the invention is the expansion of technological capabilities by ensuring the removal of parts from both the lower and upper halves of the stamp by installing a pivot arm on the upper half of the stamp.

The drawing shows the proposed device, side view.

The device for removing parts comprises a pivoting lever 1 mounted on the upper half of the stamp by means of an axis 2 and spring-loaded with a spring 3, a stand 4 mounted on the lower half of the stamp. A pivotal pawl 5 is fixed on the stand by means of axis 6. Depending on the design of the stamp, the spring 3 may be a compression, expansion or torsion spring. In the lower half of the stamp is made i stop 7 under the pivot arm.

The device works as follows.

As the press ram moves down the lever's shoulder, it rests against the dog.

5, rotates on axis 2 and brings the unit 3 to the operating state. Continuing downward movement, the lever arm 1 passes the dog 5. At the same 5 times, the second lever arm contacts with the stop 7.

During the course of the slider up one shoulder of the lever rests on the dog 5 from the charger, rotates it, and passes freely up. The second shoulder, having passed the stop 7, under the action of the spring 3 enters the working zone of the stamp and clicks the part out of the working area.

In case the part is located in the upper part of the working tool and is pushed out by the pushers from the traverse of the press, the first, lowering

20 down relative to the top tool, experiencing vertical force from the pushers and lateral force from the surface q of the lever arm and when reaching the upper end point

25 slider under the action of these forces is removed from the work area.

The invention makes it possible to remove parts from both the lower and upper 3Q halves of the stamp.
