Analysis of Numerical Simulation in the Deep Drawing of Box-Shaped Parts Using Variable Blank Holder Force

Abstract:

Article Preview

Blank holder force of box deep drawing is studied changes with time and displacement by DYNAFORM numerical simulation software. The results shows that, when the straight edge part of the blank holder force is constant, rounded part adopts small blank holder force can significantly improve the forming limit of box deep drawing, but the wrinkle is still evident. If the straight edge and rounded part of the blank holder force changes with time, not only deep drawing limit increase, wrinkles are also significantly reduced, indicating that the forming limit of the box shaped part is more effective on the blank holder force changes over time than with the position variation.
