introduction：The drawing progressive die requires the material to be machined to have good plasticity，Must be able to adapt to multiple drawing without affecting the drawing form due to cold hardening。This is due to the belt material during the deep drawing process，Intermediate annealing is not possible，Its also not easy to use lubricants。When the progressive die is drawn，The dimensions of the workpiece should be in50mmbelow，Material thickness less than1.2mm，The thickest is not greater than2mm。 Considerations for designing deep drawing progressive dies： 1、 Because the holding force required for the first deep drawing is smaller than that of the subsequent processes，Therefore, the pressing ring of the first drawing process and the preceding cutting process must be separated from the pressing ring of the subsequent processes
