The variable blank holder force (VBHF) deep-drawing process of Al sheet is studied by the finite element method, and based on the VBHF, a new technique of variable punch velocity (VPV) is proposed. The simulation indicates that this new servo-flexible stamping can improve the deep drawability of Al sheet obviously. The limited drawing ratio (LDR) of Al circular cup is improved from 1.48 to 1.60, and the height Al square cup is improved from 19.8 to 39.8 mm. Finally, the Al hood of one car of drawing process is simulated by the new technique, and results show that the deepness of Al hood is improved by about 30 %.
