从能量原理的角度出发，利用塑性理论中的界限法，仿照对金属成型工艺中讨论平板楔形模具时的分析方法，分别对机械自紧厚壁筒作单纯挤扩变形，形成死区变形，发生刨削内膛变形三种情况进行了力学分析和研究，得到了机械自紧过程中变形模式的变化规律，冲头推力与冲头锥角的关系，最佳推力的锥角选取原则和影响厚壁筒变形稳定性因素等结果。
From the energy principle point of view, the method of plastic theory is used to simulate the analysis of flat wedge die in the metal forming process. The mechanics analysis and the research on three kinds of situations of the internal bore deformation were carried out. The variation regularity of the deformation mode during the mechanical self-tightening process, the relationship between the punch thrust and the taper angle of the punch, the selection principle of the cone angle of the best thrust and the influence thickness Wall tube deformation stability factors and other results.
