在点焊焊钳上,有些铜合金零件在工作时,由于通过大电流,会使零件温度升高,影响导电性能及机械性能、以致不能正常工作,为了控制零件升温,必须在零件中通水循环冷却,而这些通水孔道形状弯曲,难以用机械加工的方法获得。为了保证零件的导电和导热性能,自前最理想的方法是采用铜铸件中嵌铸铜管的结构。 In the spot welding clamp, some copper alloy parts at work, due to high current, will make the parts temperature increases, affecting the electrical conductivity and mechanical properties, so that can not work properly, in order to control the temperature of the parts, you must circulate water in the parts Cooling, and these aqueduct shapes bend, it is difficult to use mechanical processing methods. In order to ensure the parts of the conductive and thermal conductivity, the best way is to use copper castings cast copper tube structure.
