Description

(54) STAMP COMBINED ACTION FOR CUTTING AND MECHANICAL SHEETS

one

This invention relates to a process tooling for a cold-sheet stamping and can be used in mechanical engineering.

A combined action stamp for cutting and embossing is known, containing a cutting matrix mounted on the top nlite and an embossing jawson placed inside it, as well as a pusher interacting with the press slide ejector and a nuanson matrix and puller on the bottom plate.

The purpose of the invention is to expand the technological capabilities of the stamp.

This is achieved by the fact that the stamp is provided with spring-loaded sliders, interacting with their beveled surfaces with the non-working end of the embossing punch, made with bevels. The pusher is rigidly connected to the stamping punch and is spring-loaded relative to the top plate.

FIG. 1 shows a stamp, a general view; in fig. 2 is a section along A-A in FIG. one.

The stamp contains a cutting matrix 1 fixed in the upper part of the stamp, a stamping punch 2 having a relief — a working surface interacting with a wedge mechanism and placed in the matrix.

The wedge mechanism contains wedge sliders 3, interacting with a non-working, which bevels with the end face 4 of a stamping punch 2; wedge rack 5, mounted on the bottom plate 6; pusher 7, which is rigidly connected to the embossing punch 2 and operating from the press ram ejector, and buffer 8. The wedge sliders 3 are equipped with springs 9. On the bottom 6, there is a punch-matrix 10 and a spring-loaded puller 11 carrying clamps 12.

When the press is creeped down, the parts 13 are first cut down by the cutting punch 10,

which is fitted over the matrix 1 with a minimum gap.

To prevent chipping of the cutting edges of the die, they need to be rounded. At the end of the slide stroke, the part 13 is stamped by a stamping punch 2. In the case of stamping a part having a relief surface on both sides, the punch 8 also has a corresponding surface.

During the course of the slide up, the protrusions of the wedge pillars 5 move the sliders 3, which act on the embossing punch 2, which pushes the finished part 13 out of the matrix 1.

Due to the relief surface of the embossing punch 2, the part 13 engages with it. The removal of the part 13 from the embossing punch 2 is carried out by cutting edges of the matrix 1 while the punch is pulled into the matrix by the buffer 8.

During deep embossing, in order to improve the reliability of the removal of the part 13, several protrusions are allowed on the clip stand 5, the process of removing the part is repeated several times. In the extreme upper position of the press ram, the embossing punch 2 is separated from the matrix 1 by the pusher 7.

The reciprocating movements of the embossing punch 2 relative to the cutting edge of the die 1 ensure reliable removal of the finished part 13 at a considerable depth of the relief of the punch 2.
