摘　　要：为了解决管型母线的难焊接问题,基于搅拌摩擦焊成形原理,我们自主设计研发了一套管型母线搅拌摩擦焊接设备。该设备利用焊接工具整体回转的工作方式对管型母线YOZ平面上的环缝进行高效率焊接,开发了管径大小可调节的工件夹持装置、尾部匙孔可消除的焊缝收弧机构以及相对压下量大小可动态调节的压力控制系统,同时设计稳定廉价的平移轴代替复杂昂贵的旋转轴满足倾角焊接工艺要求。结合设备的导辊压辊等辅助机构,管型母线可在热力联合作用下高质量成形。实验测试表明,该设备各系统功能明确且相互协调,焊接顶锻力最高可达10000 kN,为管型母线的搅拌摩擦焊接工艺研究提供了可靠的支持。In order to solve difficult welding problem of tubular busbars, based on the forming principle of friction stir welding, we designed and developed a friction stir welding equipment for tubular busbars independently. The equipment uses the working mode of integral rotation of the welding tool to weld the annular seam on the YOZ plane of the tubular busbar with high efficiency, and a clamping device with adjustable pipe diameter, a welding seam ending mechanism that can eliminate the key hole at the tail, and a pressure control system with dynamic adjustment of the relative reduction were developed. At the same time, a stable and cheap translation shaft was designed to replace the complex and expensive rotating shaft to meet the requirements of the inclination welding process. Combined with auxiliary mechanisms such as guide rollers and pressing rollers of the equipment, the tubular busbar can be formed with high quality under the combined action of heat and pressure. The experimental test shows that the functions of each system of the equipment are clear and coordinated with each other, and the welding pressure can reach up to 10000 kN, which provides reliable support for the research on the friction stir welding process of the tubular busbar.
