摘　　要：在整体旋压式无心轴托辊管体的缩颈旋压过程中 ,旋压变形力对旋压成形有着重要作用 ,本文采用变形材料均一、各向同性以及变形前后材料体积不变的原则 ,推导出旋压力的公式并给出了估测旋压力的简化公式。根据无心轴托辊管体缩颈旋压的特点 ,通过试验检测的旋压力值与估测值接近 ,证明此简化公式在工程应用上非常简单方便 ,并且能够满足要求。During the pipe spinning process of the new type unitary spindleless roller, spinning deformation force is important to metal spinning forming. Adopting the principle of deformed material uniform and the volume of material constant in the deformation process, the paper discusses the method to calculating roller journal reduction spinning force and gives the simplex formula of estimating the spinning force. On the basis of characteristics of roller's journal reduction spinning deformation, the spinning force values from experiments approach estimating values, which proves the simplex formula of estimating the spinning force can be used in project to satisfy requirements.
