(54) STAMP BENDING UNIVERSAL

I

The invention relates to the processing of metals by pressure, in particular to equipment for sheet metal stamping.

A well-known universal bending stamp containing a punch composed of two

popumatrix matrix and ejector 1.

The pusher of such a stamp is replaceable, i.e. For each size, it is necessary to produce an ejector with the appropriate dimensions, which increases the cost of manufacturing the stamp and reduces labor productivity.

The aim of the invention is to increase labor productivity and reduce labor costs for manufacturing stamp.

This is achieved due to the fact that the die matrix has protrusions, and the ejector is made up of two parts, each of which is located on the corresponding floor of the matrix with the possibility of moving along the stamping axis along the protrusions of the floor of the matrix.

FIG. 1 shows the proposed universal bending stamp, general view; in fig. 2 is a view along arrow A in FIG. one.

The stamp has the top 1 and bottom 2 plates. On the top plate 1, the left 4 and right 5 semi-punches are moved by a screw 3.

On the bottom plate 2 there are movable 1 screws 6 levs 7 and rights 8 semi-matrixes, which are made with protrusions 9 (Fig. 2), and an ejector 10 made of two parts, one of which is HMset, the possibility of vertical movement along the protrusions of the left semi-matrix 7 and each other, along the protrusions of the right semi-matrix 8. The ejector-1r is equipped with screws 11, the heads can be moved with traverse 12. The traverse 12 through the pusher 13 is connected to a buffer press device.

The stamp works as follows.

When adjusting the stamp, the left 7 and the right 8 half-matrix by moving along the lower pit 2 with screws 6 adjust to the desired outer size of the part. Left 4 and right 5 half-punches by moving

Invention Formula

Universal flexible bending stam: containing a punch, a matrix and an ejector composed of two matrixes, characterized in that, with a view to increasing labor productivity and reducing labor costs for manufacturing a stamp, the matrix is provided with protrusions, and the repeller is made of two parts of which is located on the corresponding half-matrix with the possibility of movement (along the punching axis along the protrusions of the semi-matrix.
