Warm isostatic pressing machine

Abstract

The invention relates to an isostatic pressing machine, particularly relates to a warm isostatic pressing machine, and solves the problems that an existing warm isostatic pressing machine is complex in structure, low in efficiency, large in energy consumption and poor in working condition. The warm isostatic pressing machine comprises a rack, wherein a pressurizing oil cylinder is installed on an upper beam of the rack, a high-pressure cavity located under the pressurizing oil cylinder is installed on a lower beam of the rack, a piston rod of the pressurizing oil cylinder can be inserted into the high-pressure cavity in a sealed mode, a heat conduction tank is also included and filled with heat conduction oil, an electric heater is arranged in the heat conduction tank, an oil injection hole is formed in the bottom of the high-pressure cavity, an oil return hole is formed in the top of the high-pressure cavity, and the heat conduction tank communicates with the high-pressure cavity through a heat conduction pump, a one-way valve and the oil injection hole by means of a pipeline and further communicates with the high-pressure cavity through an oil return pipe and the oil return hole. The warm isostatic pressing machine is technically characterized in that the mode that the high-pressure cavity of the isostatic pressing machine obtains high pressure is changed into a direct pressurization mode from an injection mode, and defects of an existing warm isostatic pressing machine are overcome.

Description

technical field [0001] The invention relates to an isostatic press, in particular to a warm isostatic press. Background technique [0002] Isostatic presses are divided into cold isostatic presses and hot isostatic presses. They all use fluid as the working medium to transmit static pressure. The difference is that the working medium of hot isostatic presses not only transmits static pressure but also transmits Heat, if heat transfer oil is used as the working medium, the working temperature range of the heat transfer oil is the working temperature range of the hot isostatic press, which can be from room temperature to nearly 400°C; the pressure can be from tens to hundreds of MPa, such Hot isostatic presses are also called warm isostatic presses. For the convenience of description, the hot isostatic presses studied in the present invention are collectively referred to as warm isostatic presses below. [0003] Both the warm isostatic press and the cold isostatic press use ...
