An arc-shaped top hammer type four-sided top ultra-high pressure device

Abstract

An arc-shaped top hammer type four-sided top ultra-high pressure device, the device includes a cylinder with a cylindrical structure, a support ring installed outside the pressure cylinder through interference fit, and a support ring installed outside the support ring through interference fit. For the centering support ring, the upper and lower ends of the cylinder are respectively provided with mutually symmetrical top hammers in the middle, and both sides of the centering support ring are respectively provided with radial and mutually symmetrical arc-shaped top hammers. The present invention uses four top hammers on the upper, lower and left and right sides to pressurize the pressure cylinder, and the pressure force is closer to the "hydrostatic pressure", so that the pressure cylinder can withstand greater pressure and has better pressure maintaining performance. The heat preservation performance of the top pressure cylinder on both sides is maintained, and the side is pressurized by an arc-shaped top hammer, so there will be no prestress relaxation and creep, so that the pressure cylinder is always under stable pressure during work, and the fatigue strength is high. It is not easy to be damaged, and the stability of pressurization is higher, and it has a very ideal technical effect.

Description

technical field [0001] The invention relates to the technical field of ultra-high pressure and mechanical manufacturing, in particular to an arc-shaped top hammer type four-sided top ultra-high pressure device. Background technique [0002] The double-sided top ultra-high pressure device, originally invented by H.T.H all l of the American G.E company, can generate a high pressure of 5-20G Pa, and the double-sided top ultra-high pressure mold is one of the key components of synthetic diamond, and because of its good pressure holding performance, stable pressure, High pressure is widely used in the production of gem-grade diamonds. The pressure cylinder is expensive because it is made of cemented carbide, and the pressure cylinder is the most important pressure-bearing component. The service life and pressure-bearing capacity of the mold are the main indicators to measure the level of the mold. Therefore, the safe use of the cylinder and the reduction of stress directly affect...
