分析了环件轧制变形的啮合运动性质，基于空间啮合理论建立了环件轧制孔型的一般设计方法，并进行了实例设计计算。本文解决了复杂形状环件轧制孔型设计理论问题，对于环件轧制技术的应用和发展具有实际意义。
The meshing motion of ring rolling deformation was analyzed. Based on the theory of space meshing, the general design method of ring rolling pass was established, and the design calculation was carried out. This paper solves the problem of the design of the pass hole of complex shape ring, which has practical significance for the application and development of ring rolling technology.
