Pressure transmission device for superhard composite material

Abstract

A conductive heat transfer tube is arranged in a plastic cavity, conductive heat transfer sheets are plugged at two tube ends of the conductive heat transfer tube, a porous salt column coaxial with the conductive heat transfer tube is arranged in the conductive heat transfer tube, and each hole of the porous salt column is filled with a superhard composite material. Salt sheets are filled between the conductive heat transfer sheets and the ends of the porous salt column, through holes allowing the conductive heat transfer pipes to enter are formed in the centers of the surfaces of the two ends of the plastic cavity, the conductive heat transfer pipes and the two through holes are coaxially arranged, and conductive pressure transfer structures abutting against the conductive heat transfer sheets are arranged at the through holes in a sealed mode. The superhard composite material is placed in each hole to prepare a plurality of components at the same time, so that the production efficiency is effectively improved, and the porous salt column and the salt sheet are molten in a high-temperature and high-pressure environment, so that each finished product is uniformly pressed in the preparation process, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of superhard composite materials, in particular to a pressure transmission device for superhard composite materials. Background technique [0002] In the prior art, the synthesis of diamond, cubic boron nitride, and other superhard and superhard composite materials mostly uses a six-sided top press, and six top hammers on six sides form a cube shape, which can be placed in a pressure transmission of corresponding size. medium cavity. When the six-sided top press works, the six top hammers act on the cubic pressure transmission medium and generate high pressure inside the cavity. During the loading process, part of the pressure transmission medium is squeezed, and the medium is distributed among the 6 top hammers to form sealing edges at the 12 sides of the cube. Part of the external loading force acts directly on the pressure transmission medium through the top hammer surface, generating high pressure in t...

Problems solved by technology

However, due to the influence of its own structure, not only can it not increase the output, but also it will inevitably cause uneven top pressure during the pressure transmission process of the top hammer.
