摘　　要：空心件楔横轧成形过程比较复杂 ,作者根据楔横轧变形原理和变形特点 ,指出楔横轧变形有明显的宏观拉拔特性 ;进行了空心件楔横轧成形过程的应力分析 ;研究了空心件楔横轧成形过程壁厚变化的规律 ,并给出了根据工艺条件预测壁厚变化值的公式。A deformation process of cross wedge rolling for hollow parts is very complicated. In the paper, the deformation principle and characteristics of cross wedge rolling were described and it showed a significant drawing characteristic. The stress and the law of wall thick change during the forming process of hollow parts by cross wedge rolling were analyzed. Finally, a formula used for predicting the change of wall thickness by the process parameters was given. The results obtained in this study could be used for a hollow part deformation by the similar process.
