| Abstract: | For investigating mechanism of multi-wedge cross wedge rolling(MCWR) forming the slandering of automobile semi-axes,the paper developed three-dimension parameterized model of the MCWR process forming slandering of automobile axes according to the characteristics of MCWR rolling process.The program of finite element simulation is worked out aiming at the MCWR process forming automobile axes.It is analyzed particularly that the rules of stress distribution in the work piece at every stages include the knifing zone,the stretching zone in main wedges.This study provides the reliable theory foundation for design of MCWR dies rolling automobile axes and choose of process parameters. |
