摘要:

为了揭示工艺参数对连杆衬套性能的影响,采用二次回归正交试验方法,对连杆衬套经强力旋压及热处理后的性能进行研究。对强力旋压后的试件进行热处理后,再进行拉伸试验。给出了强力旋压时减薄率、进给比和热处理时的温度等工艺参数对零件的抗拉强度、伸长率及断面收缩率的影响规律,并获得了优化的工艺参数组合和抗拉强度、伸长率及断面收缩率的回归方程。通过本次试验,得出了符合连杆衬套性能要求的工艺参数。
 

In order to reveal the impact of process parameters on performance of connecting rod bushing , the properties of connecting rod bushing after power spinning and heat treatment were studied using quadratic regression orthogonal experiment. The specimen after power spinning was heat treated,then tensile test was conducted.The effects of parameters such as thinning ratio,feed ratio and temperature of heat treatment on tensile strength, elongation and reduction of area were obtained,and the optimal combination of process parameters and the regression equation of tensile strength, elongation and reduction of area were obtained.Through the experiment,the process parameters met the performance requirements of connecting rod bushing were obtained.
