摘　　要：目的针对TU1触头托零件工艺中加工效率低、生产成本高、加工后得到的零件表面质量难以达到要求等缺点,提出了一种新的冷精锻成形工艺方案。方法利用Deform-3D软件对其成形过程进行数值模拟分析,得到变形挤压力及等效应力应变分布规律。结果利用一次挤压能够完全成形斜边槽及端面台阶,并且在此基础上设计了触头托成形模具,通过实验方法成形出了尺寸精度和表面质量均符合要求的零件。结论表明了该工艺方案和模具结构设计的可行性和实用性,为触头托零件的批量生产提供了一种更经济有效的方法。The paper aims to propose a new cold forging process scheme to solve shortcomings such as low processing efficiency, high production cost and poor surface quality of the part obtained in the process of TU 1 contact joe. The forming process was simulated by Deform-3D software, the deformation force and the equivalent stress and strain distribution rule were obtained A single extrusion could be able to fully shape the hypotenuse groove and the end step, and on this basis, the forming die of contact joe was designed. Parts of size accuracy and surface quality in line with the requirements were formed through experiment. The process program and die structure design have feasibility and practicability and provide a more economical and effective method for mass production of contact joe.
