Abstract

Abstract:

In order to improve the forming quality of multi-position progressive stamping and reduce the cost of diemanufacturing,the stamping process of the structural part used for car door rail is simulated in terms of bendingdrawing,trimming,shaping and flanging as well as of springback after unloading.Then,such forming defects ascarrier distortion,cracks in the process of deep drawing,flanging and springback are predicted and analyses on whythose defects occur are performed.Moreover,corresponding measures for solutions to or control of such problemsare raised,which aid to rebuild the finite element model,and thus ideal simulation results are made.Finally,aprogressive stamping trial is carried out according to the simulation results,and a set of qualified left-right car doorrails is successfully produced by means of double-die symmetrical pressing method.In addition,the manufacturedprogressive die is able to meet the requirement of mass production.

Key words: multi-position progressive stamping, forming quality control, carrier distortion, crack, springback
