为了解决某油缸导向套在锻造中填充率较低、成形载荷较高的问题,基于Matlab软件和数值模拟,建立了参数变量(锻造温度、压机速度、飞边槽桥部高度和宽度)与目标函数(填充率、成形载荷)之间的数学模型。通过优化得到了最佳参数组合:锻造温度1150℃、压机速度80 mm/s,桥部高度2 mm,桥部宽度10 mm。试验结果表明该方法是可行的。 In order to solve the problem of low filling rate and high forming load of a cylinder guide sleeve in forging, parameter variables (forging temperature, press speed, height and width of flash bridge) are established based on Matlab software and numerical simulation. The objective function (fill rate, forming load) between the mathematical model. Optimum parameters were obtained through optimization: forging temperature 1150 ℃, press speed 80 mm / s, bridge height 2 mm, bridge width 10 mm. The experimental results show that this method is feasible.
