Abstract

The invention provides a shot blasting forming method based on friction stir machining local plasticization. The shot blasting forming method based on friction stir machining local plasticization includes the following steps that firstly, a tensile deformation region of a part to be machined is determined; secondly, local friction stir machining is performed on the tensile deformation region, so that a friction stir region is formed; and thirdly, shot blasting forming is performed on the part to be machined. The method has the beneficial effects that a friction stir machining local plasticization method is adopted and combined with shot blasting forming, so that the shot blasting forming limit and shot blasting forming accuracy of a large-curvature wall board component can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of integral wall plate shot peening forming, in particular to a shot peening forming method based on friction stir processing and local plasticization. Background technique [0002] Shot peening technology uses high-speed shot blasting to hit the surface of the metal plate, causing the impacted surface and its underlying metal material to undergo plastic deformation and elongate, so that the plate is gradually bent and deformed toward the sprayed surface to achieve the desired shape. a forming method. This technology began in the early 1950s and gradually developed with the wide application of aircraft integral panel parts. Because this forming method does not require special molds and presses in the forming process, the forming method is flexible and diverse, and is very suitable for small batch production. Therefore, it is widely used in the overall wall panels of aircraft wings, fuselages and launch vehi...
