Analysis of process parameter influence on deformation mechanism in multi-wedge cross wedge rolling

  • As to the difficulty of frequent work-piece failure and technological parameter selection by experiment in multi-wedge cross wedge rolling (MCWR) for long-axle parts, a multi-wedge command stream program in FEM was developed by authors to simulate the MCWR rolling process. The effects of forming angle, spreading angle and reduction in area on the inner equivalent stress, strain and axial displacement of work-pieces were theoretically analyzed and the corresponding regularities were obtained. The rule of the effect of reduction in area on the axial displacement of work-pieces was verified by experiment.
