摘　　要：压制成型是电力绝缘元件的主要加工方法,具有广泛的市场前景。本文对真空接触器中的绝缘横梁构件的压制成型工艺进行研究,采用ANSYS有限元分析软件模拟绝缘横梁模具在压制成型的加热过程,借助数值计算软件数值求解绝缘横梁的保温过程,基于求解结果的详细分析,优化了成型过程中的工艺参数,给出了两种加热改进方法:一是在低温区域的加热增强,并且缩短加热时间。二是优化保温过程中电热管的温度设定值,解决了实际生产过程中遇到的产品质量缺陷问题。实验证明生产中采用该优化参数可有效提高产品的质量,缩短生产周期。Press forming is the main processing method of power insulation components, which has a certain market prospect. In this paper, the pressing and forming technology of the insulating crossbeam component in the vacuum contactor is studied. ANSYS finite element analysis software is used to simulate the heating process of the insulating crossbeam mold in the pressing process, and the numerical calculation software is used to solve the insulation process of the insulating crossbeam. Based on the detailed analysis of the solution results, the process parameters in the forming process are optimized. Two methods of heating improvement are given: one is to enhance the heating in the low temperature area, and to shorten the heating time. The second is to optimize the temperature setting value of the electric heating pipe in the process of heat preservation, so as to solve the product quality defects encountered in the actual production process. Experiments show that the optimization parameters can effectively improve the quality of products and shorten the production cycle.
