| Abstract: | A thermal-mechanical coupled model for 3-roll cross wedge rolling had been established with the aid of FE software Deform-3D by using rigid-plastic FEM.According to the results of finite element simulation,the metal flowing rules in plastic deforming were discussed.The study of stress and strain field distribution of the workpiece was given.Force parameters of 3-roll cross wedge rolling were researched.It has important theoretical sense and using values on solving part precision forming and workpiece quality improvement. |
