Device and method utilizing laser light to induce compound stamping formation

Abstract

The invention relates to a device and method utilizing laser light to induce compound stamping formation. The device comprises a flume; the flume is internally provided with a cushion block, a micro molding die and a blank holder; by utilizing laser-induced plasmas and a cavitation collapse-induced shock wave as a workpiece formation force source, a laser beam performs focusing in a through hole of the blank holder through a lens group, a laser focus point and the defocusing amount of the surface of a workpiece are regulated to enable the workpiece formation effect to reach the best effect, and the laser-induced plasmas and cavitation bubbles are sequentially produced on the surface of the workpiece; and the workpiece generates plastic deformation under the effects of a plasma shock wave and the cavitation collapse-induced shock wave, and finally, workpiece stamping formation is realized through the micro molding die. The method provided by the invention is a brand new compound formation method and greatly increases the stamping depth of the workpiece compared with a cavitation formation method; and meanwhile, due to underwater formation, compared with laser impact formation, the method can reduce the influence of the laser thermal effect to the maximum and ensures the surface formation quality of the workpiece.
