SU421170A3 - STAMP FOR TREATMENT OF SHEET MATERIAL - Google Patents

Description

one

This invention relates to a combination of dies for processing sheet material and can be used in machining.

A stamp for processing sheet material is known, which comprises a punch holder fixed on the top plate with punches, for example cut-out, a pressing guide of cut punches with openings for guide columns and a matrix mounted on the bottom plate.

The purpose of the invention is to provide, simultaneously with the cutting, the straightening of the sheet material.

This is achieved by the fact that the mechanism for moving the pressing guide is provided with an individual hydraulic drive.

In addition, in the proposed stamp, an additional forming punch can be placed on the clamp-guide, which is located between the cut punches and interacts with the corresponding recess made in the die. The surface of the punch is formed by two inclined planes intersecting at an angle lying within 155 ° 20 - 178 ° 30.

The direction of the column can be provided with a compensational control pads, which are fastened at their ends.

FIG. I shows the proposed stamp in the upper position; on phpg. 2 - the same, in the lower position; in fig. 3 - the finished product.

The press plate 2 (not shown) fastens the top plate 2 of the punch, on which is attached the holder 3 with cutting punches 4. Cylinders 5 of the individual hydraulic drive are placed in the plates and plug holder 3, the pistons 6 of which are connected to the clamp-guide 7, alternating along the guide columns 8. The clamp-nannula 7 is equipped with guide punched punches 4 sleeves 9, fixed in the clamp-nanowire 7 with a plastic aid 10, for example, epidian. Prigpm-direction ypiz 7 is spring-loaded relative to plnty-matrix 11 spring 12 and is equipped with a forming iryanson 13.

The guide of the column 8 is fixed on the bottom plate 14 of the stamp installed on the press table 15 and equipped with compensation pads 16 and 17. regulating

the distance between the clamp-guide 7 and the plate-matrix 1 with screws 18 and 19. In the plate-matrix 11, a recess 20 is made.

When fluid is supplied to cylinders 5 pistons

b move the pressing guide 7, which clamps the sheet material 21, and the punch 13 carries out the molding of the material 21.

Then, the slider 1 begins to fall with the plate 2, the punch holder 3 and the cut punches 4 drying the cutting and bending of the sheet material.

Then, the slider 1, the plate 2, the punch holder 3 and the pressing guide 7 are raised to the upper position, after which the work cycle is repeated.

Subject invention

1. A stamp for processing sheet material containing a punch holder attached to the upper nlite with puns, for example, cut-out, a pressing guide of cut punches with openings for guide columns and mounted on

The bottom nlite matrix, characterized in that, in order to carry out simultaneously with the cutting of the sheet material, the mechanism for moving the pressure guide is equipped with an individual hydraulic drive. 2. Shtamp according to claim 1, characterized in that a further shaping punch is placed on the pressing-nanravlachuyu located between the cut punches

and interacting with a corresponding recess made in the matrix, and the surface of the nuance is formed by two inclined planes intersecting at an angle within 155 ° 20-178 ° 30.

3. Stamp on PP. 1 and 2, characterized in that the guide columns are provided with regulating layers, fastened at their ends.
