SU1237282A1 - Arrangement for removing parts from die working zone - Google Patents

Description

The invention relates to the processing of metals by pressure and can be used to remove from the working area of the concave extrusion dies the successive effect of the transversal waste during low waste stamping or parts during wasteless stamping,

FIG. 1 shows the proposed device for removing waste (parts) from the working area of the stamp; in fig. 2 is a view A of FIG. one; Figures 3 to 4 show the cutting patterns of the material with low-waste and non-waste stampings using the proposed device.

The device for removing parts from the working zone of the stamp comprises a gripper 1 fixed on axis 2 in body 3, a spring 4, constantly clamping gripper 1 to an emphasis 5 fixed on a lid 6 fixed on the body 3 and forming with it a curved channel 7 for transportation of waste (parts) outside the working area of the stamp.

A device for removing parts from the working area of the stamp operates as follows.

The material is fed up to the stop 5, the length of which is chosen so that when the punch is opened, the stop does not come out of engagement with the die.

When closing the stamp, zhyat 1 and the stop 5 cover the cross web of the material on both sides, ensuring accurate fixation of the material at the moment of cutting. At the end of the turn, the grip 1 with its ustzgom drops under the desired surface of the material.

As the slider moves up, the part supported by the shoulder of the gripper 1 rises together with the movable part of the stamp.

On the next strike, the newly bent part raises the previously cut part up through channel 7 by the amount of material thickness, etc. Over time, the channel is completely filled and the parts begin to pour out on the other side of it into the container or onto the container (not shown).

The curvature of channel 7 for the exit of parts is adjusted depending on the width of the transverse crosspiece; and material, and the radius of curvature should be 8-20 times the length of the jumper.
