Prefabricated body dipping and cracking integrated automatic production equipment and use method

Abstract

The invention relates to impregnation and cracking integrated automatic production equipment for preforms. The prefabricated body dipping and cracking integrated automatic production equipment comprises a control system, a manipulator and an automatic rotating table. The automatic rotating table is located below the mechanical arm, and the automatic rotating table and the mechanical arm are both associated with the control system; a dipping mechanism and a cracking mechanism are mounted on the automatic rotating table; the dipping mechanism comprises a dipping cylinder, a cylinder cover, a lifting assembly, a vacuum pump and a precursor container, the cracking mechanism comprises a high-temperature cracking furnace, a furnace cover, a lifting assembly and a protective gas cylinder, and a heating and heat preservation assembly is arranged in the high-temperature cracking furnace. The preform impregnation and cracking integrated automatic production equipment has the advantages of continuous impregnation and cracking, automatic sample taking and placing, barrel cover opening and closing, pressure monitoring and the like, and solves the problems that existing impregnation and cracking equipment cannot realize continuous production and is low in production efficiency due to excessive manual participation.

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...
