Abstract
The invention relates to a titanium alloy thin-wall hollow structure forming method and a forming evice, belongs to the technical field of material forming, and solves the problems of complicated forming process and large loss of a thin-wall hollow structure in the prior art. The titanium alloy thin-wall hollow structure forming method comprises the following steps that, 1, a hollowed-out plate is prepared; 2, a face plate is prepared; 3, a covering plate is prepared; 4, the hollowed-out plate, the face plate and the covering plate are assembled in a upper mold and a lower mold; 5, diffusion bonding and superplastic forming are carried out; and 6, the weight reduction area is removed. According to the method, the hollowed-out plate and the covering plate are adopted, one-time forming of the weight reduction area is achieved, and the problem of oxidation of a thin-wall plate in the hot forming process in the non-vacuum environment is effectively solved.
Description
technical field [0001] The invention relates to the technical field of material forming, in particular to a forming method and a forming device for a titanium alloy thin-walled hollow structure. Background technique [0002] With the development of equipment manufacturing in the direction of high speed and light weight, light materials, optimized structures and simplified connection forms are currently being pursued. [0003] Lightweight structure refers to the manufacture of structural parts with higher strength and stiffness and lighter overall weight through overall optimized design and the introduction of lightweight manufacturing technology. In addition to the use of lightweight materials such as titanium alloys, aluminum alloys, and magnesium alloys for lightweight structures, another important approach is to use "substituting empty space for solid" in structure. [0004] As a high-strength metal material, titanium alloy has excellent fatigue resistance and excellent ...
