楔横轧空心件稳定轧制条件分析

Analysis on Stable Rolling Condition of Hollow Workpiece Rolled by Cross Wedge Rolling

引入塑性铰概念，用平面应变理论和能量法研究了楔横轧空心件的平均单位正压力和压扁条件，并推导了楔横轧空心件的稳定轧制条件．

Using the concept of plastic hinge, the average unit pressure and squash condition are researched with the theory of plane strain and energy method. So, the stable rolling condition of hollow workpiece rolling by cross wedge rolling is presented.
