Abstract:

一种外送丝等离子熔敷修复液压支架立柱的方法,能提高立柱的耐磨和耐腐蚀性能,提高生产效率,延长寿命。方法是1)对液压支架立柱进行除锈、清洗工作;2)对立柱进行加工,在立柱的旋转运动及等离子枪线性轴的进给运动配合下,采用外送药芯焊丝的方式对工件进行熔敷;3)对熔敷层表面经行机械加工至镜面光泽度。喷嘴到立柱表面的距离5~10mm,转移弧电流100~130A,电压为20~50V,熔敷速度200~380mm/min,立柱的旋转速度为0.5~2r/min,送丝速度1~3cm/s,搭接率20%~40%,焊丝药粉为:高碳铬铁:1~2.5wt.%,金属铬粉:18~23wt.%,金属镍粉:10~15wt.%,钼铁:9~14wt.%,45#硅铁:1~2.5wt.%,金属锰:2~4wt.%,硼铁:6.0~15.3wt.%,余量铁粉。
