基于有限元分析的方法,分析了摩擦系数对冷滚打成形过程齿坯温度分布以及冷滚打成形力的影响。研究结果表明:在不同成形阶段,随着摩擦系数的增加,齿坯温度上升,滚打成形力增加。增加滚打轮和齿坯之间的润滑能有效减小成形力并提高齿轮零件的加工精度。 Based on the finite element analysis method, the influence of the friction coefficient on the temperature distribution and cold forming force of cold forming during cold forming was analyzed. The results show that, at different forming stages, as the friction coefficient increases, the temperature of the blank increases and the rolling forming force increases. Increasing the lubrication between the rolling wheel and the tooth blank can effectively reduce the forming force and improve the machining accuracy of the gear parts.
