Abstract：

The circular plate rim was symmetrically thickened by the method of spinning under heating conditions，and a diskshaped part with a thin web and a thick rim was obtained finally. Then, the finite element model was established by ABAQUS software, and the symmetric thickening forming process was studied. The results show that during the hot spinning symmetric thickening forming process, the radial spinning force is gradually increased, while the axial and tangential spinning force are relatively small. The studies on the process parameters indicate that the small friction coefficient μ and groove incline angle α are favorable for forming, and large feed ratio f is more suitable. With the increasing of lengthtothickness ratio γ and forming thickening ratio η, the symmetric thickening forming process exhibits different deformation characteristics. When γ is too large, the forming is prone to buckling instability, however, when η is too large, the forming is prone to bulge instability. Finally, the thickening experiment is conducted by choosing a set of suitable process parameters, and the experiment result is in good agreement with the simulation result to verify the process reliability.
