The micro-blanking automation device comprises a laser generating system, an automatic forming system and a control system, wherein the laser generating system is composed of a laser controller, a laser emitter and an optical fiber, the automatic forming device is composed of an end cap, a focusing lens cone, a machine body, a micro-blanking worktable, a three-coordinator moving chuck, a base, a varying magnetic field device, a rotary table multi-position device, a restraint layer-fly piece integrated piece, a restraint layer-fly piece integrated piece storage bin and a recovery device. According to the micro-blanking automation device and method of the sheet metal under the indirect impact of the laser, pulse laser is used as a forming power source, energy conversion between optical energy and mechanical energy is conducted through a restraint layer-fly piece integrated piece device, and therefore automation of the micro-blanking technology that the sheet metal is loaded through a fly piece driven by the pulse laser is achieved. The automatic forming system is relatively independent, the machining precision is free from external interference, and personal errors are avoided. Both laser circuits and the micro-blanking worktable are stored inside the machine body so that safety of experimental operation is improved.

AI Technical Summary

Problems solved by technology

However, the current laser-driven flyer micro-blanking technology device cannot perform continuous micro-blanking of metal sheets under the indirect laser impact, and its mass production is only the formation of multiple dies under the impact of one pulse, which is not fast and continuous in the true sense. Mass production, and because the workpiece and fixture need to be re-clamped after a laser shock forming in this device and method, it is bound to bring human error due to manual operation and affect the processing accuracy

Moreover, the open laser light path also has certain potential safety hazards
