Description

one

The invention relates to the processing of materials by pressure and can be used, for example, dp synthesis of diamond, cubic boron nitride and other superhard materials.

A multi-punching device 1 is known, comprising punches installed in pairs in the central recesses of the lower and upper base plates and a guide formed in the form of a ring and located between the plates along the plane of their connector. The guide surfaces for the punches are formed on the inner surface of the ring.

With greater press forces, the dimensions of the individual parts of the device, including the guides, must be increased, which causes additional difficulties in their manufacture and operation.

The aim of the invention is to simplify the manufacture and maintenance of a multi-punching device.

This goal is achieved by the fact that the guide is made in the form of individual wedges installed between each pair

punches, and in the plates there are grooves for installation of wedges with emphasis in their vertical walls.

FIG. 1 shows a multi-punch device in section; in fig. 2 - section A-A in FIG. one.

The multi-punching device consists of the coaxially mounted upper 1 and lower 2 base plates of the same design. The upper plate is made in the form of an insert 3, on which the slip ring 4 is pressed. The lower plate is made in the form of an insert 5, on which the fastening ring 6 is pressed. The inserts 3 to 5 are composite. Each slab has a central four-fold recess. A punch 7 is mounted on each face of the recess.

Between the punches 7 is placed a container 8 in the form octasch) a, in which a hole is made, filled with the reaction composition dp of synthesis of superhard materials. In the aazor between the poashes; onami 7, a clutch 9 is made of elastic material, for example rubber. Between pin 1 and 2, along the plane of their connector.

Moving to the center of the device, the punches 7 compress the container, creating pressure in it. A portion of the material of the container 8 is squeezed into the gaps between the punches to form an awensee. Coupling 9 ensures uniform formation of all burrs. After the required pressure has been created, the reaction composition is heated, for which a spectral current is passed through it. using a special heating device (on the drawing, conventionally not in a lazano). When heated, noansons 7 that are in contact with the peaiujjiOHHbiM are used as current connectors.
