Abstract
To further improve the material utilization in cross wedge rolling, the paper simulated the forming of closed cross wedge rolling through DEFORM-3D, a rigid-plastic finite element analysis software, and analyzed the distribution and changing rule on the fields of strain and displacement in the parts rolling. Then the paper clarified the generated mechanism about the end concavity of shaft in the closed type of cross wedge rolling, which has great theoretical significance and engineering applied value in controlling and decreasing the end concavity in closed type cross wedge rolling and improving the parts’ end quality.
