Abstract：

A four-step spinning forging process was designed for this kind of disc-shaped parts with non-uniform thickness. The forming process of spinning forging was analyzed by finite element simulation technology, and the effects of the groove size parameters for the spinning wheel (top tilt angle α, bottom fillet radius R and groove depth l) on the forming stability and the flow lines of the rim section were studied. The groove parameters of spinning sheel for each step was optimized sequentially, the best combination of process parameters was obtained and it was verified by process experiment. The results show that the optimized parameter combination can obtain better forming quality, and the thickness for wheel rim of a circular plate is successfully thickened from 3 mm to 9.1 mm. The rim section and flow lines distribution obtained by simulation are in good agreement with the formed part by experiments.
