摘要：

铜质触指是高压开关的核心功能结构件，其制造性能直接决定了高压开关的服役性能和使用寿命。以铜质高压开关触指为研究对象，对其多自由度摆动辗压成形工艺的设计方法开展了研究。基于Deform-3D有限元模拟平台，建立了三维有限元仿真模型，探究了坯料形状及飞边形式对铜质高压开关触指多自由度摆动辗压成形的影响。并揭示了成形过程中等效应力、等效应变和成形力的变化规律。研究结果表明，采用仿形坯料和纵向飞边可以获得成形效果较好的铜质高压开关触指。在上述研究基础上，最终进行了工艺实验，获得了成形质量良好的铜质高压开关触指样件，证明了所提出的铜质高压开关触指多自由度摆动辗压成形工艺设计方法的有效性。

Copper contact finger is the core functional structure component of high-voltage switches, and its manufacturing performance directly determines the service performance and service life of high-voltage switches. Therefore, for the copper high-voltage switch contact fingers, the design method of multi-degree of freedom (DOF) swing rolling process was studied. Then, based on the Deform-3D finite element simulation platform, a 3D FE simulation model was established, and the influences of blank shape and flash form on the multi-DOF swing rolling of copper high-voltage switcher contact fingers were investigated and the variation laws of equivalent stress, equivalent strain and forming force during the forming process are revealed. The research results show that the copper high-voltage switch contact finger with good forming effect can be obtained by using the profiled blanks and the vertical flash. Based on the above-mentioned research, the process experiment was finally carried out, and the qualified copper high-voltage switch contact finger samples were obtained, which indicates that the proposed design method for multi-DOF swing rolling process of copper high-voltage switch contact fingers is effective.
