活塞杆连续驱动摩擦焊接工艺参数的设计

Design of Continuous Driven Friction Welding Parameters for Piston Rod

通过正交试验得出:在活塞杆连续驱动摩擦焊接工艺参数中,影响接头抗拉强度的主次顺序是:顶锻保压时间、顶锻压力、主摩擦压力、主摩擦时间;其优化组合为:主摩擦压力7.6MPa、主摩擦时间19s、顶锻压力14.3MPa、顶锻保压时间16s,并通过实验进行了验证,实验结果与正交试验计算结果基本一致。

By orthogonal experiment,the sequence of technological parameters of continuous driven friction welding effecting the strength of the welded joint of piston rod were： upset pressure time,upset pressure,main friction pressure and main friction time.The optimization combination is： main friction pressure 7.6MPa,main friction time19s,upset pressure 14.3MPa,upset pressure time16s,which are validate by experiments.The field obtained from experiments is consistent with that of the calculated results.
