Abstract：

The structural and stamping process characteristics of the car cooler buffer were analyzed. The reasonable multi-position forming process scheme was formulated. The multi-position progressive stamping process including drawing, sizing, punching and flanging was simulated numerically by the Dynaform software. The forming limit diagram(FLD) and the thickness distribution for each process were analyzed. The simulation results meet the requirements of part. According to the simulation results, twelve-position progressive stamping die was designed, and the qualified product was produced by the die-testing. Through the comparison between simulation and die-testing, the maximum relative error of the product thickness is only 2.87%, which shows good consistency. At present, the car cooler hood progressive die has been put into mass production.
