Abstract

The invention relates to isostatic pressing machines, in particular to a universal dry type automatic isostatic pressing machine. The universal dry type automatic isostatic pressing machine solves theproblems that the existing dry type isostatic pressing machine is poor in universality and low in automation degree. The universal dry type automatic isostatic pressing machine comprises a machine frame and a forming assembly located on the machine frame; the forming assembly consists of a high-pressure cavity assembly, a barrel-shaped high-pressure cavity seat and a balancing oil cylinder whichare sequentially arranged from top to bottom; and the high-pressure cavity assembly comprises a cylinder-shaped high-pressure cavity, a cylinder-shaped rubber female die is arranged in the high-pressure cavity, the high-pressure cavity assembly further comprises a lower die piston arranged inside the high-pressure cavity seat, the lower die piston is vertically fixed with a columnar lower die whose upper end can extend into a lower opening of the rubber female die in a sealed mode, the high-pressure cavity assembly further comprises a balance cylinder connecting rod positioned between the lower die piston and a balance cylinder piston rod, and the lower end of the balance cylinder connecting rod is movably connected with the end of the balance cylinder piston rod. The universal dry type automatic isostatic pressing machine realizes the universality of the dry type isostatic pressing machine, the automation degree of the dry type isostatic pressing machine is improved, and a foundationis laid for the wide application of the dry type isostatic pressing machine.

Description

technical field [0001] The invention relates to an isostatic press, in particular to a general-purpose dry automatic isostatic press. Background technique [0002] The isostatic press is an industrial equipment that uses static pressure for powder molding. It is characterized by high density and uniform molding products, which cannot be replaced by any other powder molding equipment. The existing ordinary isostatic pressing molding process is to first put the powder into the rubber female mold, the powder fills the mold cavity in the mold, and after sealing, put it into the liquid pressure medium in the high-pressure chamber of the isostatic press, and pressurize it. During the process, the static pressure of the pressure medium is transmitted to the powder through the deformation of the mold until it is extruded. After molding, take the mold out of the liquid pressure medium in the high-pressure chamber, clean the mold and then open the mold to take out the workpiece. [...
