A super-high pressure working cylinder structure of a warm isostatic press

Abstract

The invention discloses an ultrahigh-pressure working cylinder structure for hot isostatic pressing machines, which mainly comprises a working cylinder body, an upper end cover and a lower end cover, the upper end cover is arranged on the upper end of the working cylinder body, and the lower end cover is arranged on the lower end of the working cylinder body. The ultrahigh-pressure working cylinder structure is characterized in that the working cylinder body comprises a core barrel (1), an insulating layer (2) and a cooling interlayer (3), the cooling interlayer (3) is arranged between the core barrel (1) and the insulating layer (2), and the upper end cover and the lower end cover are respectively arranged on the upper and lower ends of the core barrel (1). Not only is the structure of the ultrahigh-pressure working cylinder structure simple, but also the cost is low, and the ultrahigh-pressure working cylinder structure also can meet the service requirement of a hot isostatic pressing working cylinder, and thereby can carry out hot isostatic pressing operation under the working condition of temperature lower than 300 DEG C, so the ultrahigh-pressure working cylinder structure is suitable for popularization and use.

Description

technical field [0001] The invention relates to a working cylinder structure, in particular to an ultra-high pressure working cylinder structure of a warm isostatic press. Background technique [0002] The ultra-high pressure working cylinder is an important part of the warm isostatic press. It is used to form a closed space filled with a liquid with a certain temperature. After placing the pressurized product inside, the closed space is pressurized to realize the temperature of the product. Repressive work in the environment. During the pressing process, it is necessary to keep the internal pressure and temperature as constant as possible, and at the same time, the temperature field inside the working cylinder should be as uniform as possible. [0003] The main difference between the warm isostatic press and the cold isostatic press is the temperature. In addition to the ultra-high pressure required for carrying the work, the warm isostatic press also needs to bear a certa...

AI Technical Summary

Problems solved by technology

Since the working cylinder needs to carry ultra-high pressure, its components are all metal materials, and metal is a good conductor of heat, the internal heat is easily lost through heat conduction and heat radiation, resulting in a drop in the internal temperature of the working cylinder

In addition, after the internal temperature is transmitted to the outside, the surface temperature of the working cylinder will rise, which will cause the danger of burns to the operator, and will have a certain impact on the surrounding devices
