Abstract
The invention relates to a forming method and a forming device of a titanium alloy thin-walled hollow structure, which belongs to the technical field of material forming and solves the problems of complicated forming process and large loss of the thin-walled hollow structure in the prior art. The invention provides a method for forming a thin-walled hollow titanium alloy structure, comprising: step 1: preparing a hollow plate; step 2: preparing a panel; step 3: preparing a cladding plate; step 4: assembling the hollow plate, the panel, and the cladding plate In the mold and the lower mold; Step 5: Perform diffusion bonding and superplastic forming; Step 6: Remove the weight-reducing area. The invention adopts the hollow plate and the covering plate, realizes the one-time forming of the weight-reducing area, and effectively solves the oxidation problem of the thin-walled plate in the thermoforming process in a non-vacuum environment.
Description
technical field [0001] The invention relates to the technical field of material forming, in particular to a method and a forming device for forming 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, the pursuit of light weight of materials, optimization of structure, and simplification of connection forms are currently being pursued. [0003] Lightweight structure refers to structural parts with higher strength, rigidity and lighter overall weight through overall optimized design and the introduction of lightweight manufacturing technology. In addition to using lightweight materials such as titanium alloys, aluminum alloys, and magnesium alloys, another important way is to use "empty instead of solid" in the structure. [0004] As a high-strength metal material, titanium alloy has excellent fatigue resistance and excellent corrosion resistance, and its ...
