2) individual working chamber is placed on five-shaft numerical control workbench, five-shaft numerical control workbench computer system control;
3) die is placed in working chamber, and die is fixed by screws on five-shaft numerical control workbench, then magnesium alloy plate to be formed is placed on die, and make post flexible lamina one to face up;
4) be fitted on the flexible lamina of magnesium alloy plate upper surface to be formed by two flatting apparatus symmetries, simultaneously, two conductive fixtures are clipped in respectively the two ends of being with shaping magnesium alloy plate, with wire, conducting wire clamp and high energy pulse power supply are coupled together, five-shaft numerical control workbench, laser instrument and computer control i system are electrically connected;
5) protective gas nitrogen is filled with in working chamber, makes nitrogen be full of working chamber, then seal;
6) start-up simulation machine control system, laser instrument is made to send laser, spot diameter is 200um-10mm, flexible lamina is arrived by reflective mirror, meanwhile, start high energy pulse power supply, make it produce high-density current and pass through conductive fixture, magnesium alloy plate is inner, while entering magnesium alloy plate, the high-density current that high energy pulse power supply produces enters in magnesium alloy plate by conductive fixture, atoms permeating in promotion magnesium alloy plate and the vigilant defect motion of high density dislocation, alleviate the work hardening phenomenon that laser pulse hits magnesium alloy plate, reduce its resistance of deformation, improve magnesium alloy plastic forming performance, obtain the profiled member that bulging height is 8-45mm, improve magnesium alloy molded internal microstructure, complete the strengthening of magnesium alloy plate, obtain profiled member,
7) open the seal of working chamber, take off flexible lamina and profiled member.
Further, preferred scheme is: the thickness of described magnesium alloy plate is 1mm-5mm.
The invention has the beneficial effects as follows: by Plastic Forming effect and laser-impact high strain rate dual improve processability technology to magnesium alloy plate work together carry out shaping with strengthening, increase forming limit and the press height of magnesium alloy, obtain the profiled member that bulging height is larger.
