Paper Title:
Numerical Simulation and Verification of Multi-Operation Sheet Forming Process for Stamping Parts of Spiral Step Surface
  Abstract

On the basis of in-depth simulation analysis of stress and strain, thickness and forming limit changes in the property sphere during the drawing process for the stamping part of the spiral step surface, combined with the comprehensive simulation analysis of flanging, punching and other operations for the parts, it is concluded that the most obvious non-uniform changes of sheet thickness occur in the drawing process and then in the flanging process. The possibility and the distribution of tension fracture in ironing and wrinkles in thickening has been predicted and the production feasibility of low-cost drawing process without the blank holder and multi-operation forming process for stamping parts of spiral step surface. The validity of multi-operation numerical simulation results has been verified by the actual measurement of finished product rate and product thickness in trial production.
