Air guide system of superplastic forming/diffusion bonding die and manufacturing method of air guide system

Abstract

The invention discloses an air guide system of a superplastic forming / diffusion bonding die and a manufacturing method of the air guide system, the air guide system of the superplastic forming / diffusion bonding die comprises a die body, an air guide channel, an exhaust hole, a plug and a pipeline connector; a plurality of exhaust holes are formed in the mold body; an air guide channel is arranged in the mold body in a penetrating manner, a plurality of ports are formed in the side wall of the mold body by the air guide channel, one port is connected with the pipeline interface, and the other ports are provided with plugs; and the exhaust hole is communicated with the air guide channel. In addition, the invention further provides a manufacturing method of the air guide system for the superplastic forming / diffusion bonding mold, and according to the air guide system for the superplastic forming / diffusion bonding mold and the manufacturing method of the air guide system for the superplastic forming / diffusion bonding mold, the air guide channel is formed in the mold body in a penetrating mode; the problem that an external welding pipeline air guide system is not suitable for a large number of exhaust holes is solved, and the beneficial effect that the air guide system is suitable for a small number of exhaust holes or a large number of exhaust holes is achieved.

Description

technical field [0001] The present application relates to the technical field of superplastic forming / diffusion joining, in particular to an air guide system of a superplastic forming / diffusion joining mould and a manufacturing method thereof. Background technique [0002] The superplastic forming / diffusion joining process can be used to manufacture multi-layer hollow structures with complex shapes and curved surfaces and reinforced inner ribs. Compared with the composite components fastened by traditional joining methods, this process has the advantages of light weight, good integrity and high quality. It has greatly improved the design freedom and structural efficiency of components, and has become an important processing method for multi-layer board reinforcement structures in the aerospace field. [0003] When forming parts with complex curved surface structure, more exhaust holes with diameters of φ1-φ2 ​​should be set at the inner corners or low-lying places of the mol...
