Analysis of Axial Deformation of Cross Wedge Rolling Asymmetric Shaft Part Based on Finite Element Method

Aimed at preventing the problems of axial movement, step blemish and rolling overlap piece of skins which make from the imbalance of axial and tangential force because of asymmetry of parts in size and shape, the paper adopted finite element method (FEM) to simulate CWR technique of typical asymmetric shaft part, and analysis systematically axial force and axial displacement. Then we can judge axial offset by axial displacement of central point of billet. The results of the study indicate that FEM can manifest the axial deformation of asymmetric shaft parts in CWR, which provides theoretical foundation for the promotion of CWR technology in the application of asymmetric shaft parts manufacture.
