介绍了楔横轧成形过程的工艺参数及变形区参数，分析了楔横轧展宽区的金属变形情况及推导了变形区参数的工程计算公式。文末对鲤鱼钳毛坯进行了实例计算。%In this paper, the technology parameters and the parameters ofdeformation region in forming process of the cross wedge rolling were introduced. The metal deformation condition of the spreading region on cross wedge rolling was analysed and the engineering calculation formulas of deformation region parameters were derived from. In the end an example is given to calculate for the blank of the slip joint pliers.
