Abstract：

Symmetrical thickening spinning is a special spinning process for disc-shaped parts with thin spoke and thick rim. Therefore, the deformation laws and forming characteristics of blank, the cause of defects and the influences of process parameters on forming in the two-step symmetrical thickening spinning process were studied by finite element simulation. The results show that friction coefficient μ, feeding speed v of the roller and rotation speed ω of blank have little effect on the forming process, while groove bottom width of roller h, inclination angle α of roller groove and length to thickness ratio γ of blank have sigmificant effect on the forming in the first step. With the increasing of groove bottom width of roller h and inclination angle α of roller as well as length to thickness ratio γ of blank, the blank is more prone to lose stability and form defects. Furthermore, in the second step, the groove bottom width h of roller and the initial shape of blank have significont effect on the forming. Meantime, the fillet radius R at the bottom of roller groove can improve the stress state of the outer edge of blank, and the larger the R is, the more obvious the improvement effect is.
