用ANSYS/LS -DYNA软件对楔横轧轧制过程进行非线性有限元模拟 ,得到轧件端头凹心的形成原因 ,总结出模具成形角、展宽角、轧件端头尺寸及轧细长度等因素对轧件端头凹心大小的影响规律 ,并将计算结果与实验结果进行比较 ,其规律一致。本研究对合理确定楔横轧工艺参数、提高材料利用率具有重要的意义 The nonlinear finite element simulation of the cross-wedge rolling process was carried out with ANSYS / LS-DYNA software to get the formation reason of the concave end of the rolling stock. The forming angle, broadening angle, the size of the rolling end and the rolling length And other factors on the size of the end of rolling the impact of law, and the calculation results and experimental results were compared, the same law. This study is of great significance for the reasonable determination of cross-rolling cross-rolling process parameters, improve material utilization
