Abstract：

To investigate the influence of process parameters on the forming quality of high strength steel DP600 cup-shaped part during the single-pass drawing spinning, by taking the distribution of wall thickness, straightness and average value of roundness for spun parts as the evaluation indexes, the forming process of single-pass drawing spinning for high strength steel DP600 was simulated based on the software ABAQUS,and the simulation results were verified by experiments. The results show that, with the increase of feed ratio f, fillet radius rρ of roller and relative clearance δ between roller and mandrel, the uniformity of wall thickness becomes better and the straightness increases; the average roundness decreases at first and then increases, and an optimal value exists. The optimal forming quality can be obtained by the parameter combination of f=0.5 mm·r-1, rρ=10 mm and δ=-5% for the single-pass drawing spinning of high strength steel DP600 cup-shaped parts.
