轧机联轴器主传动轴的装配焊接工艺研究

Study on assembly welding technology for the main drive spindle of rolling mill shaft coupling

通过研究轧机联轴器主传动轴的装焊工艺,总结出一套对于多段拼焊的细长空心轴通过焊接坡口形式的确定、焊前粗调、精调方法以及焊接工艺参数合理设定,最终通过焊接来保证同轴度的装焊工艺方案。该制作方案对类似产品的制作提供了良好的技术借鉴,值得推广应用。

This article stt,died the welding sequence of the main drive spindle of rolling mill shaft eoupling,and summarized a manufacturing scheme for multiple tailor welding slender hollow shafts.In the manufacturing scheme,through the determination of welding groove form,coarse tuning and fine tuning before welding,and setting reasonable welding parameters,the coaxiality can be ensured through welding finally.The manufacturing scheme provides favorable technology reference value for the manufacturing of similar products,and it is worth popularization and application.
