An integrated automatic production equipment for impregnation and cracking of prefabricated body and its use method

Abstract

The present invention relates to an integrated automatic production equipment for prefabricated body impregnation and cracking. The integrated automatic production equipment for preformed body impregnation and cracking includes a control system, a manipulator and an automatic rotating table. The automatic rotating table is located under the manipulator. The automatic rotating table and the manipulator are all associated with the control system, and the automatic rotating table is equipped with an impregnation mechanism and a cracking mechanism; the impregnation mechanism includes an impregnation cylinder, a cylinder cover, a lifting assembly, a vacuum pump and a precursor container, The cracking mechanism includes a high-temperature cracking furnace, a furnace cover, a lifting component and a protective gas cylinder, and a heating and heat preservation component is arranged in the high-temperature cracking furnace. The preform impregnation and pyrolysis integrated automatic production equipment has the advantages of continuous impregnation and pyrolysis, automatic sample taking, opening and closing of the cylinder cover, pressure monitoring, etc., which solves the problem that the existing impregnation and pyrolysis equipment cannot be continuously produced, and the production efficiency of excessive manual participation is solved. Not a high question.

Description

technical field [0001] The invention relates to a prefabricated impregnation and cracking integrated automatic production equipment and a use method, which belong to the technical field of impregnation and cracking. Background technique [0002] Generally, the precursor impregnation pyrolysis process (PIP) is used to transfer the preform to a vacuum impregnation equipment for impregnation. After the impregnation is completed, the preform is then transferred to a high-temperature cracking furnace for high-temperature cracking, and finally the product with the required performance is obtained. [0003] Today's aircraft brake discs such as civil aviation airliners, fighter jets, and transport aircraft are all made of carbon fiber-reinforced carbon-based composite materials, that is, carbon / carbon composite materials. For carrier-based aircraft, the friction coefficient of carbon materials will gradually decrease when the humidity is relatively high. It is the preparation of ca...
