摘要

以22MnB5钢板电阻点焊电极为研究对象，基于控制体积法对其传热特性进行了数值模拟与分析.着重对其电极温度场分布以及冷却水流场分布进行了研究，探讨了电极冷却腔底面凹角、冷却水管与冷却腔底距离、冷却水管端面切角等因素对电极散热能力的影响规律，并在此基础上对电极结构进行了优化设计.结果显示，在不影响电极正常工作的前提下，优化后电极的冷却能力有显著增强，完全冷却时间较优化前减少2 s.

Abstract

In this paper，numerical simulation

based on volume controlled method

is used to study and analyze the heat transfer characteristics in the electrode of spot welding for 22MnB5 steel. The study focuses on the field distribution of electrode temperature and cooling water. It also explores the factors influencing heat dissipation capability of electrode

such as the concave angle on the bottom surface of electrode cooling cavity

the distance between the cooling water pipe and the bottom surface

and the endface corner cut of cooling water pipe

upon which electrode structure is optimized. The results show that

in normal operation

the cooling capacity of the optimized eletrode has greatly improved and the total cooling time is 2 s less than that of the non-optimized one.
