| 摘 要： | 应用弹塑性弯曲矫直理论,对矫直过程进行了深入分析,对直径和直径误差与矫直压下量之间的关系进行了研究.计算结果表明,矫直后的直线度与直径误差无关,矫直效果随直径的增大而改善,最佳的相对压下量一般在O.64～O.77之间,与实验达到了较好的吻合.研究结果提出了最佳的矫直压下量选择方法,为提高矫直精度和制定最优工艺提供了理论依据.

| Abstract: | Using elastic-plastic straightening theory,the straightening process was analyzed,and the relationship between of diameter,diametrical error and straightening reduction rate was studied by the theoretical calculation.Analysis results indicate that the linearity after straightening is independent of diametrical error,and straightening effectiveness is improved by increasing diameter,and optimum relative reduction rate are normally between 0.64-0.77,which is in conformance with the experimental results well.T... |
