Abstract：

In view of the optimization requirements of the easily damaged pawl parts for the feeding mechanism of multi-station cold heading machine, based on modeling of the ratchet mechanism by Cero, Workbench static analysis was used to solve and comparatively analyze the maximum deformation amount, equivalent stress, frictional stress and allowable safety factor of static strength of the original pawl material of 60Si2MnA steel, Cr12MoV steel, 20CrMnTi steel and 42CrMo steel under normal conditions. The research results show that Cr12MoV steel can better meet the needs of the pawl for the feeding mechanism. Under normal working conditions, it can effectively reduce the maximum deformation amount and equivalent stress of the pawl, increase the life of the pawl component, and improve the accuracy of the feeding material length for the feeding mechanism. The optimized and innovative design has been applied to the multi-station cold heading machine which achieves good results.
