Abstract

The invention discloses an isostatic pressing sealing structure which comprises pressing plates, metal rings and nonmetal sealing rings. The pressing plates are arranged on an end cover of an isostatic pressing device, and a circle of step part is arranged on each edge of the end cover, and a circle of convex part stretching towards the corresponding step part is arranged on the edge of each pressing plate. Each step part is provided with one metal ring, and the metal rings are provided with concave parts matched with the convex parts of the pressing plates. The side face, in contact with the side wall of the corresponding step part, of each metal ring and the other opposite face, in contact with the inner wall of a working cylinder barrel of the isostatic pressing device, of the metal ring are each provided with a groove, and the nonmetal sealing rings are arranged in the grooves. The isostatic pressing sealing structure prevents working media in working cylinders from flowing out of the gaps between the metal rings and the inner walls of the working cylinder barrels, ensures sealing between the working cylinders and the end cover and enables an isostatic pressing device to work normally.

Description

technical field [0001] The invention relates to the technical field of isostatic pressure equipment, in particular to an isostatic pressure sealing structure. Background technique [0002] Isostatic pressing is a technology in the field of powder metallurgy. Isostatic pressing machine is a complex equipment. According to the temperature of the working medium, it is divided into cold isostatic pressing machine, warm isostatic pressing machine and hot isostatic pressing machine. It is composed of a working cylinder and a frame, and the working cylinder is composed of an end cover, a core tube, a sealing structure, etc. The inside of the working cylinder is a liquid or gas with a certain temperature and ultra-high pressure as the working medium, and there is a gap between the end cover and the core tube. A certain gap must be filled by a sealing structure, and only a reliable sealing can form a closed container in the working cylinder. Only the pressure of the working medium t...
