Optimization of the Blank Holder Stiffness in Deep Drawing Processes by using FEA
When deep drawing the parts with complex geometry, changeable thickening can occur in the flange area. Extreme thickening of the part flange will cause pressure peaks at the contact surface between blank holder and part. This undesired occurrence during deep drawing will reduce process window and process robustness as well. In this paper, an approach to optimize the blank holder stiffness in deep drawing process is presented.
