Pressed-film ultra-hard material synthesizer

Abstract

Compression mode superhard material synthesis equipment, including the upper mold of the synthetic cavity and the lower mold of the synthetic cavity correspondingly provided with a hemispherical groove in the central part, the distal part of the upper mold of the synthetic cavity and the piston in the piston cylinder of the power source, and the lower mold of the synthetic cavity The far end of the die is axially fixedly connected to the top of the lower support body of the press, and the power source piston is connected to the side of the lower support body of the press through a connection frame. The upper mold and the lower mold of the synthetic cavity are composed of a small cylindrical section, a truncated cone section and a large cylindrical section from the far end to the proximal end, and the top of the lower support is cylindrical; the outer end of the piston is connected with the small cylindrical section and the upper mold of the synthetic cavity. The frustum section, the top of the lower support body are fixedly connected with the small cylindrical section and the frustum section of the lower mold of the synthetic cavity through a coupling sleeve which is sleeved on the outside thereof and consists of a cylindrical cavity and a vertebral cavity. The cone section of the inner cavity of the connecting sleeve is in an interference fit with the upper mold and the lower mold cone section of the synthetic cavity. A cooling water channel is provided inside the matching part of the connecting sleeve and the upper mold and the lower mold of the synthesis cavity. The invention has the advantages of simple structure, small equipment investment and good use effect.

Description

technical field [0001] The invention belongs to the technical field of superhard material synthesis equipment, in particular to a pressure mode superhard material synthesis equipment. Background technique [0002] The six-sided top press synthesis equipment is a special equipment for diamond production. It is usually made of identical six hinged beam assemblies connected by pin hinges. It is simple to manufacture and easy to install. However, there are gaps in the hinge connections of this press, and after matching, the cumulative error is large, the spatial position accuracy of the six-cylinder piston of the press is poor, the synthetic pressure stability of diamond is poor, and the cost of synthetic equipment is high, and the equipment investment cost is high. . The synthetic block is cylindrical, the pressure field and temperature field are not easy to control, and the mass difference between each volume unit of the synthetic block is large.
