| Abstract: | 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. |
