Description

one

The invention relates to the field of forge-and-press engineering, namely, devices designed to separate die blocks.

A device is known for separating the blocks of a punch, comprising, its base, mounted with the possibility of mixing, in the direction of the base, movable racks, fixed racks, as well as pick-up devices 1.

The disadvantages of this device are the use of manual labor, with the result that a small bursting power is achieved. In addition, the stripper grips are not included in the work of the entire surface, but part of it is inserted at a certain angle, which leads to distortions and jamming of the stamp blocks when the strippers are detached and broken.

It is not possible to use the device to break blocks of dies having an elongated shape.

The aim of the invention is to mechanize manual labor and improve the technological characteristics of the device.

This goal is achieved by the fact that the movable racks are installed on the base with the possibility of reciprocal reciprocating movement from the hydraulic drive and are integral with the pick-ups, and the fixed stands are installed on the movable racks and are made in the form of power cylinders with the synchronous movement of plungers, on which 5 other pick-ups are located .

FIG. 1 shows a device for separating punch blocks with grippers-removers (a - in the extreme retracted position, b - in the working position); on

10 of FIG. 2 - the same, top view.

The device for separating the blocks of the stamp contains a base 1 with guides 2, in which stands are located — the lower grippers-pullers 3 with clamps 4, the power cylinders 5 of the horizontal stroke with the plungers 6, the power cylinders 7 of the vertical stroke with plancers 8, the upper grips-pullers 9 , lower block-stamp 10 with grooves 11, upper block-stamp 12 with

20 grooves 13.

The lower grippers-pullers 3 are mounted on the base 1, with the clips 4 being inserted into the guides 2. The horizontal cylinders 5 are fixedly mounted on the base 1, and their plungers 6 are attached to the lower grippers-pullers 3. The vertical cylinders 7 the strokes are mounted on the bottom 30 of these pick-ups 3, and on their plunger 8 are located the upper capture-strippers 9.

The operation of the device is as follows.

The upper 3 and lower 9 grippers-strippers or cylinders 6 of the power cylinders 5 of the horizontal stroke are retracted to the extreme position and the lower block-punch 10 is installed with the jas 11 and the upper block-stamp 12 with the jases 13. Then simultaneously from the sides by the power cylinders 5 horizontally, the grippers pullers 3 and 9 are put into the grooves I and 13 of the block-dies 10 and 12.

Then, synchronously with the plungers 8 of the cylinders 7 of the vertical stroke by the upper grippers-detachable hooks 9, the upper block stamp 12 rises above the lower block stamp 10 held by the lower hooks of the puller 3, releasing the stamp guide columns (not shown).

The number and diameter of the power cylinders 5 and 7 is selected depending on the required power of the device.

The device contains two cylinders 5 horizontal stroke and four cylinders 7 vertical stroke.

In order to replace block strains, the lumens formed (not shown) are formed in the gap formed at rupture, the pressure in the power cylinders 7 is relieved, and the upper block-stamp 12 smoothly lowers onto the gaskets and the power cylinders 5 retracts the pickups 3 and 9.

Thereafter, the different block-stamp is removed from the device, and a new one is installed in its place, and the process is repeated.

The use of the proposed 1 OZZolit device to mechanize hand piles, to provide a reliable plug of the gigamps without distortions and jamming, will create the possibility of using a device for the numerical range of stamps of various shapes.
