Specific to the serious problem of rupture,wrinkling and springbck of box-shaped stamped parts,the processes of drawing,cutting,correcting shaping of magnet cover with arc top and straight sidewall were simulated using the finite element analysis software DYNAFORM,and the forming law of the parts was analyzed.The influences of the process parameters,such as blank holder force(BHF),die radius,die clearance and punching speed,on stamping property were investigated by using the orthogonal experiments.Taking th...
