中文摘要：针对电动工具用端面齿，采用刚塑性有限元法对其冷锻成形过程进行了分析，获得了材料变形过程中的等效应力、等效应变和成形载荷的分布规律。根据模拟结果分析了金属流动规律。研究表明：法兰下端面和弧形齿下端角隅处是最难充填区域，该类零件的成形宜用冷锻成形工艺。
英文摘要：Through rigid-plastic finite element method, the cold forging process for tooth of face gear used in electric tools was analyzed. The distribution of equivalent stress, equivalent strain and forming load was obtained. Depend on the simulation results, the rule of metal flowing was got. The results show that the areas of the bottom corners of the flange and arc gears are difficult for forming, and the cold forging process fits for these parts.
