摘　　要：结合楔横轧成形工艺中需要解决的突出问题,通过分析内直角台阶成形过程中几何形状的研究现状,考虑楔横轧内直角台阶成形过程中各主要几何影响因素,建立了符合实际的内直角台阶成形全过程的轧件表面几何模型及其数学表达式,推导出整个轧制过程中轧件的旋转半径公式.Based on geometrical models during the whole process of forming inside right-angled step in cross wedge rolling which were proposed in past years, an effective geometrical model was built through generally analyzing the geometrical influencing factors of forming inside right-angled step. Mathematic representations of the surfaces and turn radius of the part in the whole process of rolling were derived.
