根据楔横轧工艺的特点,推导了椭圆轴在轧齐过程中螺旋斜锥体大端半径随轧件转角变化的旋转公式.通过对轧齐过程的分析,获得了各阶段的体积公式,并依据体积平衡原理得到了椭圆轴直角台阶轧齐曲线.最后采用刚塑性有限元软件Deform-3D对椭圆轴的轧齐过程进行了模拟,取得了良好的结果,同时验证了曲线方程的正确性.
According to the characteristics of the wedge cross rolling process, the rotation formula of the large radius of the spiral cone in the process of rolling is derived. The volume formula of each stage is obtained by analyzing the rolling process According to the principle of volume balance, a right-angle step-rolling curve of elliptical shaft was obtained.Finally, the rigid-plastic finite element software Deform-3D was used to simulate the process of oval axis rolling, and the good results were obtained. Meanwhile, the correctness of the curve equation was verified.
