摘要：

针对多工位冷镦机送料机构的棘爪部件易损坏的优化需求，在采用Cero对棘轮机构建模的基础上，采用Workbench静力学分析对原棘爪材料60Si2MnA钢、Cr12MoV钢、20CrMnTi钢以及42CrMo钢这4种备选材料在正常状态下的最大变形量、等效应力、摩擦应力以及静强度许用安全系数进行求解和对比分析。研究结果表明：Cr12MoV钢更能满足送料机构棘爪的需求，在正常工作的状态下，能有效地减小棘爪的最大变形量和等效应力，提高棘爪部件的寿命，提高送料机构进料料长的精度。该优化创新设计目前已在多工位冷镦机上应用，效果良好。

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.
