摘　　要：为了提高强力旋压连杆衬套的产品质量、使用寿命及可靠性,减少由于机械磨损而产生连杆衬套失效问题,针对不同工艺参数条件下的旋后筒形件硬度,采用单因素试验方法进行分析,研究了减薄率、进给比、旋轮1减薄量及退火温度对旋后筒形件硬度的影响。结果表明:随着减薄率、进给比、旋轮1减薄量的增大,筒形件内外层表面硬度随之增大,但随着退火温度的升高其硬度呈逐渐降低趋势;筒形件轴向表面硬度由底部向口部逐渐增大,径向表面硬度从外向内逐渐递减。In order to improve the product quality,service life and reliability of the power spinning of connecting rod bushing,and reduce the connecting rod bushing failure problems caused by mechanical wear. The effect of thinning rate,feeding rate,reduction of roller 1 and annealing temperature on hardness of cylinder after power spinning was analyzed by using single factor experiment method. The results show that hardness in inside and outside layer increases with increasing thinning rate,feeding rate and reduction of roller 1,while it decreases gradually with rising annealing temperature. However,the axial surface hardness of cylinder increases from bottom to entrance,and radial hardness of cylinder decreases from external to internal.
