Problems solved by technology

[0005] However, due to the large amount of heat absorbed by the working cylinder of the host system of the warm isostatic press and the heat dissipation of the cylinder, the temperature of the pressure transmission medium transported into the working cylinder through the heating and filling system drops rapidly, which cannot maintain the product during the pressing process. Constant temperature in cylinder

Abstract

The invention belongs to the technical field of isostatic pressing processing equipment and discloses a temperature isostatic pressing machine which keeps temperature constancy of a pressure transfermedium in a cylinder. The temperature isostatic pressing machine comprises a heating charging and discharging system, a working cylinder and an insulating box. The heating charging and discharging system is separately provided with an inlet and an outlet, and the inlet of the heating charging and discharging system is connected to a water tank; the working cylinder comprises a cylinder and an upper end cover assembly and a lower end cover assembly which are hermetically arranged at two ends of the cylinder, separately; a drain hole is formed in the inner wall of the cylinder body, and an outlet communicating to heating charging and discharging system and a hollow channel of the cylinder body are arranged in the lower end cover assembly; the insulating box is arranged between the outer sideof the cylinder body and the inner side of the cylinder body in a sleeved manner and has a gap, and the gap between the insulating box and the cylinder body communicates to the hollow part of the cylinder body through the drain hole; a transitional cover is inserted onto the top end of the insulating box; a positioning spigot for positioning the cylinder body is arranged at the bottom end of thetransitional cover, and a through hole is formed in the inner wall of the transitional cover; and when the upper end cover assembly does not block the cylinder body, and an inner hole of the transitional cover communicates to the hollow part of the cylinder body.

Description

technical field [0001] The invention belongs to the technical field of isostatic pressing treatment equipment, and in particular relates to a warm isostatic pressing machine. Background technique [0002] The warm isostatic press seals the warm and pressure-transmitting medium in a closed working cylinder, and uses the principle of equal pressure in all directions of the pressure-transmitting medium to make the material form a specific shape under the action of temperature and pressure. The warm isostatic press is mainly composed of a host system and a heating and discharging system, and its core system is a host system that can form a high-temperature and high-pressure environment required for product molding. The host system is mainly composed of a working cylinder that can form a seal and accommodate high-pressure and high-temperature pressure transmission medium. The working cylinder is composed of an upper end cover, a lower end cover and a cylinder body. [0003] When...
