以ZX50CA钻铣床为研究对象,采用液压技术对其压下装置进行设计,设计出一台适用于镁合金薄板搅拌摩擦焊的设备,选用3 mm厚的AZ31镁合金板材进行对接焊接实验。结果表明:当搅拌头转速为1400 r/min、焊接速度为15 mm/min、压紧力为1500 N时,焊接接头表面成形良好。通过实验证明,该设备能够满足搅拌摩擦焊的工艺参数要求,适用于搅拌摩擦焊的实验研究,而且相对于大型专用搅拌摩擦焊设备,成本低,使用灵活、方便,为镁合金薄板搅拌摩擦焊设备的开发提供了很好的参考价值。

Design of Friction Stir Welding Equipment Based on Drilling-milling Machine

Taking ZX50CA drilling-milling machine as the research object, the hydraulic technology was used to modify the pressing system, a friction stir welding equipment was designed for magnesium alloy sheet. An AZ31 magnesium alloy sheet with 3 mm thickness was used for the welding experiment. The results show that when the rotating speed is 1 400 r/min, the welding speed is 15 mm/min, and the pressure is 1 500 N, the welding joint surface forms well. The experiment proves that the equipment can satisfy the requirement of the friction stir welding process parameters, suitable for friction stir welding experiment research; relative to the large-scale specialized friction stir welding equipment, it is low cost, flexible, convenient. It provides reference for development of friction stir welding equipment for magnesium alloy sheet.
