SU1423234A1 - Arrangement for fixing material in progressive die - Google Patents

Abstract

The invention relates to the processing of metals by pressure, in particular to the tooling for processing sheet material. The goal is to increase the reliability of fixation. The fixation device contains an abutment (U) 1, a stepping knife (ShN) 3, a hook (3) 4 and a wedge 6. Before starting work, U comes out into the shuffle zone, stretch the strip 9 and fixes it along the end. At the working stroke, the SN 3 cuts the groove in the lane 9. Wedge 6 retracts I and 3 4 locks it. When serving on the next step. the strip moves 3 4 and releases it from Y 1. The latter rests against the lateral edge of the strip 9 and with further mixing it falls into the groove. Then the cycle repeats. 2 Il.

The invention relates to the processing of metal blades with pressure, in particular to tooling for processing sheet material.

The purpose of the invention is to increase the reliability of work.

FIG. 1 shows the device at the beginning of the working stroke, general view; in fig. 2 - Vo, at the end of the working stroke, i The device contains an emphasis 1 with a spring-10Y 2, a stepping knife 3, a safety gate 4 with a spring 5 and a wedge 6. The support 1 and a safety wheel, a fir-tree 4 are installed in the fixed part of the mold 7, and the knife 3 and the knife 6 are in the movable part (not shown). The overhang is installed in slot 8, polished, and is indicated by 9.

The device operates as follows. Before the beginning of the working stroke, the stop 1 protrudes into the zone of movement of the strip 9, which - and rests on it with its end face. At the stroke of the stroke, the stepping knife 3 cuts down the groove 3 to the lane 9, the wedge 6 retracts the stop 1, the spinal spring 2, and the latch 4 under the action of the spring 5 moves in the groove 8 and

Aperatus emphasis 1.

When moving to a step, the strip 9 from the judder latch 4, which moves along the lash 8 and sinks in it, releases I nop 1. The stop 1 abuts against the lateral edge of the strip 9 and as it goes further

Placement falls into the groove formed by the step knife 3, fixing the pitch.

Then the cycle repeats.

The implementation of the invention will improve the reliability of fixation due to the fact that the strip during fixation against the stop does not experience from its side resistance to its movement.

Claims (1)

Invention Formula A device for fixing material in a sequential punch, containing an abutment located on a fixed plate of the stamp with movement in a plane, perpendicular to the axis of pressure, perpendicular to the direction of movement of the material and having a spring, and on the moving plate - a step blade and a wedge installed with the possibility interaction with the stop, characterized in that, in order to increase the reliability of fixation, a protrusion is made on the surface of the stop, a groove located at an acute angle is made in the plate bearing the stop in the direction of movement of the material, and the device is provided with a latch installed in the groove with the possibility of protruding into the zone of movement of the material, interacting with the protrusion of the stop and moving along the groove and having a spring. 1
