Simulated Analysis of Flow and Deformation in Trilateral Constrained and Asymmetric Square Cup Deep-Drawing
To satisfy the local forming need of sheet-metal part, numerical simulation of SUS304 stainless steel deep-drawing with trilateral constrained slot were carried out by employing the analytical software ETA/dynaform5.5. The influence of different friction coefficient and holder force on the forming quality was analyzed by taking the inflow volume while parts forming 50mm as standard. The results show that the effect of trilateral constraint on the uneven flow and deformation of flange. And some measures were illustrated to improve the quality of some of these parts.
