摘 要：应用刚塑性有限元DEFORM-3D软件对非对称楔横轧与对称楔横轧的成形过程进行数值模拟，获得对称轧制过程中轧件所受的轴向力和非对称轧制过程中轧件的轴向窜动；并通过实验验证了楔横轧非对称轴的可行性。结果表明，通过控制轴向力和轴向窜动量可以轧制出合格的非对称轴类件，研究结果对非对称轴类件的楔横轧精确成形具有重要的理论依据和应用价值。

Abstract:The forming processes of the asymmetric and symmetric cross wedge rolling were simulated numerically by rigid plastic FE software DEFORM-3D, and the axial forces of the parts suffered in symmetric rolling and the axial movement of the parts in asymmetric rolling were obtained. The feasibility of the cross wedge rolling asymmetric shaft was verified by experiment. The results show that the asymmetric shaft can be rolled by controlling axial force and axial movement, which provides important theoretical basis and application value for cross wedge rolling asymmetric shaft part accurately.

Key words:cross wedge rolling; asymmetric shaft; axial force; axial movement; feasibility
