Design of 304 Stainless Steel Deep Drawing Die
The stainless steels are widely used in every field for their beautiful appearance and good usability.However,fracture and wrinkling in deep-drawing are common defects caused by its strongly work hardening and that lead to the production yield lower.The drawing dies of a pair of lids were designed.The blanking-drawing-piercing-trimming composite processes were adopted.The device of elastic pressure side with the pressure pad was used,in order to prevent the change of the BHF.
