楔横轧齿轮轧制成形是一个全新的课题，在轧制过程中轧件的变形、温度场及力能参数都有待研究。将楔横轧技术与齿轮范成加工原理相结合，设计了楔横轧齿轮轧制的模具，给出了楔横轧齿轮轧制成形热力耦合本构模型，并在SuperForm平台对轧制成形过程进行了有限元模拟，获得了轧件在成形过程中的变形规律、温度场分布及力能参数变化等数据，详细分析了数值模拟结果，为进一步研究齿轮楔横轧制坯提供参考。

Gear preforming by cross wedge rolling is an original question for discussion, parameters such as deformation, temperature field and mechanical performance are looking forward to be researched. This paper ties the advantages of preforming by CWR and the principle of generated gear together, and the die suited for gear rolling has been designed. Based on the finite deformation theory, the coupled thermal-mechanical constitutive model of gear rolling by CWR has been established. Then FEM simulation for the forming process has been developed in MSC. SuperForm, and information gained from the simulation has been analyzed also in detail which provide references for further study of gear rolling by CWR technology.
