Description

one

The invention relates to the processing of metals by pressure, in particular, to die tooling, and can be used for dies to remove degichi from the tool and remove 113 of the working area.

The purpose of the invention is the expansion of technological capabilities by improving the conditions for removing parts from the working area by means of mechanization.

At the same time, the spring 3 is designed to hold the traverse 1 and the press hardening system in the initial position.

Another friend of the PM is an end with a dropout of a mowing surface. In this case, the spring 8 serves to retract the resetter 10 from the original nojiOMcenjie, the lesser rigidity than the rim 3.

The iia bottom plate 13 is stamped with a clamp, and 14, which includes a gpcI 15 part, connected p, p & c 1n-1 pusher 16 with a press buffer (not shown).

The device works as follows.

When the press slider is running, the upper pusher 4 is located only under the weight of the press crosshead (not shown) and does not have a strong force air, it acts on the crosshead-5p expansion spreader 1. Therefore, under the pressure of the compressed pru / kin 3 and 8 The traverse 1 ejector 10 is taken into the exiting position (Fig. 1 to the extreme left position) and is not prevented from affecting the punch 7 on the machined material.
