Abstract:

In this paper,first,a numerical model was established with UG,HyperMesh and Dynaform to simulate the strip layout of the whole 13-position progressive stamping process of automotive soleplate component parts. Next,the whole progressive stamping process was numerically simulated by using the multi-position and multiprocess method,and the forward and reverse drawing of the key positions 3 and 4 among the 13 positions was analyzed in detail. Then,the finite element model was rebuilt based on the modified shapes of blank and convex hull,by which satisfied simulation results were obtained. Finally,a progressive die with 13 positions was designed and manufactured,and a set of automotive soleplate component parts with bilateral symmetry was produced. Measured results obtained by checking fixture show that the forming quality meets the service requirements well. The designed 13-position progressive die has been used in mass production.

Key words: stamping, multi-position progressive die, automotive structural part, high-strength steel plate, whole process chain, numerical simulation
