Abstract

The invention discloses a laser shock pretreatment-assisted laser dynamic flexible micro-forming method and device, and relates to the field of laser processing and forming. The device includes a laser loading system, a plastic forming system, an automatic mold changing system and a fixture system; Supplemented by laser shock pretreatment to achieve grain refinement and then laser dynamic flexible micro-forming, through the movable mold core and core support body, grain refinement pretreatment and forming processing are realized. The invention uses a new type of micro-mold to make Before laser dynamic flexible micro-forming, laser shock grain refinement pretreatment is performed to improve its forming ability, thereby improving its micro-forming accuracy, surface quality and forming limit, and avoiding failure behaviors such as fracture caused by size effects. . At the same time, the automatic mold change system of the new micro-mould can avoid secondary clamping and effectively save production costs.
