摘要： 采用三维弹塑性有限元模拟了楔横轧的轧制过程，分析了轧制过程中金属沿轴向的相对变形规律。在比较不同工况轴向相对变形程度的基础上，获得了模具主要工艺参数对轧件轴向延伸产生的影响。研究结果对于选择合理的模具工艺参数，避免轧件成形缺陷，保证零件质量起指导作用。

Abstract: 3-D elasto-plastic finite element method is adopted to simulate the process of cross wedge rolling, the relative de- formation rule in the axial direction of workpiece is analyzed. On the base of comparing the relative deformation degree under the different rolling conditions, the influence of process pa- rameters on the axial stretching of workpiece is obtained. This result plays a guiding role on selecting appropriate parameters of the tools and avoiding the formation defects, guaranteeing the quality of parts.

Key words: Axial deformation, Cross wedge rolling, Finite element, Simulation
