The Investigation of Multi-Stage Sheet Metal Stamping Process for Deep Drawing

摘要

Based on empirical analysis and FEA modeling of multi-stage sheet metal stamping, the optimal sheet metal stamping process can be supplied. Concurrently, the effects of process parameters on formability are found by numerical simulation. Taking an example of deep drawing part, the results got from the numerical simulation are compared with experimental results, which proves that finite element analysis (FEA) is effective and accurate in optimizing the process design of multi-stage sheet metal progressive stamping.
