The invention provides a flexible high-temperature pressure device adaptive to a complex curved surface and a flexible high-temperature pressure control method. The flexible high-temperature pressure device comprises a main body framework, locating and fixing components and a pressing layer; the locating and fixing components are arranged on the two sides of the main body framework and are used for locating a curved surface workpiece; a U-shaped cavity is formed in the middle of the main body framework; and the pressing layer is arranged in the U-shaped cavity, so that constant temperature and constant pressure gluing and fixing treatment can be carried out on the curved surface workpiece. With the adoption of the scheme, the requirement on the uniformity of pressure and the temperature can be met to the greatest extent; and due to the slave motion property of the flexible high-temperature pressure device, the high precision requirements on super-long machining and assembly are met, the flexible high-temperature pressure device can completely adapt to the complex curved surface, the problem that the fitting between a pressing surface and a gluing surface is not complete is effectively solved, and the uniformity and reliability of pressure and temperature parameters in the gluing technological process of the curved surface workpiece are guaranteed.
Description
technical field [0001] The invention belongs to the technical field of constant-pressure and constant-temperature equipment for large-scale blade bonding and curing molding, and specifically relates to a flexible high-temperature pressurizing device and a control method that adapt to complex curved surfaces. Background technique [0002] At present, the blade bonding and curing molding process mainly adopts two methods: vacuum pressure and clamp manual pressure, and finally the temperature control is carried out through the constant temperature box to complete the bonding and curing process. "Manual pressure with clamps, heat preservation and curing in a constant temperature box" is a common way for large-scale blades to complete the bonding process of metal-clad and composite material blades. Partial pressure is applied to the material blades to form the pressure conditions required for bonding, and the temperature conditions required for bonding are formed as a whole in a ...
