Abstract

The invention discloses a method and device for manufacturing a metal lining of a 3D printing composite material space pressure vessel. The manufacturing method comprises the steps that an additive manufacturing environment of an environmental simulation storage tank is adjusted to a set parameter condition; a 3D printing welding gun is controlled to fuse a metal welding wire, and molten metal iscoated to a set position of the welded vessel; after the molten metal is cooled to the rough machining temperature, the frequency and the amplitude of a micro forging head are adjusted, the molten metal at the set position is pressed and forged through vibration of the micro forging head, and rough machining additive metal is obtained; a grinding milling cutter is controlled to conduct appearanceand size grinding on the rough machining additive metal until the rough machining additive metal is ground to the set accuracy, and finish machining additive metal is obtained; and layer-by-layer accumulation is carried out, the 3D printing process is completed, and a product to be processed is completed. According to the method and device, the fusing-forging integration process is used for producing the lining of the pressure vessel or a thin-walled pressure vessel, influences of machining like welding on the product quality are reduced, and the precision and the tissue performance of the molded product are improved.

Description

technical field [0001] The invention belongs to the technical field of composite material preparation, and in particular relates to a method and equipment for manufacturing a metal inner lining of a space pressure vessel made of 3D printing composite material. Background technique [0002] Compared with all-metal pressure vessels, composite overwrapped pressure vessels have the advantages of light weight, good rigidity, high vessel characteristic coefficient, high reliability, good fatigue resistance, long service life under load, and safe failure of leakage before blasting Model (Leak-before-break), strong designability, low production cost, short development cycle and many other characteristics make it more and more widely used in the aerospace field. [0003] As a pressure vessel for space, the composite material pressure vessel can effectively reduce the weight of the structure, and has a high output pressure and high safety and reliability, which can effectively improve...
