夹环是指在滚压和摩擦的压力下，环件夹住辊缝，产生旋转的滚压运动，从而使环件厚度等厚、外径等胀，这是环件滚压成形的充分条件。本文以滚环原理和静力学理论为基础，对滚道沟槽异形环滚压的夹持过程进行了分析。建立了滚道沟槽异形环轧制的夹持力学模型，并根据滚压过程中的几何关系研究了夹持条件。结果表明，通过控制每转进给量，防止每转进给量超过环件夹持所允许的最大进给量，可以保证环件连续夹紧轧制间隙。此外，还分析了夹持条件的影响因素。最后，对滚道沟槽异形环轧制进行了实验和有限元模拟，验证了夹持条件的有效性。实验和仿真结果都表明，当进给满足夹持条件时，环件可以连续夹持缝隙并通过轧制成形。否则，环不能抓住缝隙，并在辊子之间被挤压。研究结果为滚道沟槽异形环轧制工艺参数设计提供了理论依据。
Ring gripping means that under the pressure of roll and friction, ring grips the rolling gap and produces rotating rolling motion, thus ring thickness receives equal rolling and the outer diameter expands equally, and this is a sufficient condition for ring rolling forming. In this paper, gripping course in profile ring rolling of raceway groove is analyzed based on ring rolling principle and static theory. The gripping mechanical model for profile ring rolling of raceway groove is established, and gripping conditions are researched according to the geometrical relationship in rolling. The results indicate that ring could be ensured to continuously grip the gap in rolling by controlling feed per revolution and preventing it from exceeding the maximum feed per revolution allowed by ring gripping. Furthermore, influencing factors of gripping conditions are analyzed. At last, the experiments and the FE simulation for profile ring rolling of raceway groove are performed to testify the validity of gripping conditions. Both the experimental and simulation results show that when feed satisfies gripping conditions, ring can continuously grip the gap and be formed by rolling. Otherwise, ring cannot grip the gap and is squashed between the rolls. The results of this research provide a theoretical basis for design of technological parameters of profile ring rolling of raceway groove.
