Abstract：

According to the part characteristics formed by wedge rolling，the mould of big cross-sectional shrinkage solid part was optimally designed by Deform-3D software. The rolling method of forming two pieces in one mould was adopted. The big arc of piece was in the middle, the tail groove was formed first, and then the big arc in the middle was formed. It is an advantage that the rolling process is stable, and it can be cut off easily after forming. After analyzing the influence of height changes on forming results，it is found that in the final stage of wedging the wedge height changes quickly which results in big deformation and necking. A better scheme was obtained and the distribution laws of equivalent stress and equivalent strain in axial cross-sectional area were researched. The research results show that the metal equivalent stress and equivalent strain on the rolled surface and nearby are bigger，but smaller in the center，and the equivalent stress in the axial direction is distributed in arc.
