Framework type tooling for molding composite material product autoclave

Abstract

The invention discloses a framework type tooling for molding a composite material product autoclave; longitudinal reinforcement ribs and transverse reinforcement ribs are in cross connection, and are welded with a molded surface to form an integrated framework structure; the bottom of the longitudinal reinforcement ribs and the bottom of the transverse reinforcement ribs are fixedly welded with a bottom flat plate; four corner edges of the molded surface are each provided with a processing and testing datum hole of a process device, and both sides of the framework are each fixed with a hanging device; a suction nozzle is located in a central axis of both ends of the molded surface, and a suction pipe is connected with the suction nozzle and forms a pressurized gas pumping system with a suction connector; the bottom surface area of the molded surface is provided with a plurality of temperature sensors, and the temperature sensors are connected with temperature monitoring connectors by wires to form a temperature monitoring system. The surface smoothness of the tooling molded surface is good, air tightness and manufacturability are good, the service life is long, the deformation is small, temperature rising and dropping are uniform when the tooling is used in the autoclave, the tooling has good thermal conductivity and thermal stability and meets the process technology requirements of the composite material product autoclave molding, and the quality of the molded composite material product is stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of process equipment in the aviation manufacturing industry, and in particular relates to a frame-type process equipment structure for composite material parts autoclave forming. Background technique [0002] Composite materials have excellent characteristics such as strong designability, light weight, high specific strength, corrosion resistance and unique electromagnetic penetration performance, making them widely used in structural components of aerospace products, and moving structural components such as automobiles, trains, and ships. . Since the molding of composite material parts must use special molding process equipment to ensure that the material compounding process and the part forming process are completed at the same time, no further processing is required after the part is formed, and its internal structure and mechanical properties can meet the product design requirements. The quality and ext...
