摘　　要：针对钢管倒棱加工过程中的钢管钝边问题,通过对倒棱机切削原理的分析,将刀具的固定切削模型改进为浮动切削模型,并建立浮动刀座的数学模型,推导出浮动弹簧机构的选择公式.最后,利用ADAMS软件进行动力学仿真分析,得到弹簧力和弹簧位移的曲线图,为钢管倒棱机浮动切削机构的进一步优化设计提供理论支持.For the problem of steel pipe＇s blunted edge in the process of steel pipe chamfering processing, through the analysis of the chamfering machine＇s cutting principle, fixed cutting model of the tool improves for floating cutting mode , and establishing the mathematical model of the floating cutter holder, then deducing the selecting formula of floating spring mechanism. Finally, using ADAMS software to do dynamic simulation analysis, and getting the curve chart of spring force and spring displacement. It provides theoretical support for the further optimal design of steel pipe chamfering machine＇s floating cutting mechanism.
