The purpose of the invention is to expand the range of yes. parts due to the ability to remove parts with a small flange. The device contains under 3. amp. 3. Mounted on the pivot arm 2. At one end of the bar 3, an abutment 9 is fixed. And on the other end, a sub-skirted skimmer 4 connected to the cam 5 is mounted by means of the copier finger 6, fixed associated with the slider 4. To remove a part from the stamp, the lever 2 rotates, the slider 4 under the action of the spring 5 and the copier finger 6 moves forward and with its protrusion hooks the flange of the part until the very end of the ascent. 1 il.

Description

The invention relates to cold sheet punching, in particular to dies for trimming large-sized molded parts in a closed loop.

The purpose of the invention is to expand the range of parts to be removed by making it possible to remove parts with a small flange.

The drawing shows the proposed device.

The device for removing parts from the trimming die comprises a drive shaft 1 mounted on the shaft with the possibility of joint rotation of the lever 2, a lifting bar 3 rigidly fixed on the lever 2. In the groove of the bar 3 there is a slider 4 with a protrusion and a spring 5 to hold the slider in extended position. On the slider 4 there is fixed a thumb 6, which is included in the groove of the copier 7, which is fixedly connected with the cutter 8. A stop 9 is fixed at the opposite end of the strap 3.

The device works as follows.

In the initial position, the strap 3 is located in the hole of the trimming tool 8. When the press slide (not shown) moves upward, the part is released from the upper parts of the die. The shaft), rotating from a special mechanism mounted on the stamp (not shown), rotates the lever 2. The driver raises the bar 3. As a result of lifting, the finger 6, moving in the pack slot of the copier 7, sets the floor - Drying 4, which with its projection produces a hook for the flange of the part. There is a reliable engagement and holding of the part until the very end of the climb.

At the moment when the device is stopped in the upper position, the part freely rolls along the bar 3 beyond the limits of the danger zone of the stamp. An emphasis 9 holds the part against movement during movement of the slider 4. After the part has been reset, the strip 3 is lowered to its original position. Under the action of the spring about

the slider 4 is in the extended position, while the finger 6 is held in the extreme right position by the surface of the longitudinal groove made in the bar 3. Then the finger 6 enters the groove of the copier 7 and moves the slider Ј to its original position. /.
