利用有限元软件DEFORM-3D,基于三维刚塑性的有限元理论,对大断面收缩率轴类零件成形过程成功地进行了楔横轧二次楔轧制成形的数值模拟,模拟所得的轧件形状与实际零件基本相同,给出了楔横轧二次楔轧制过程的应力应变分布等重要信息。
4) second wedge rolling
二次楔成形
1.
In view of product quality of cross wedge rolling semifinished product of automotive power-shift box middle shaft which has heavy sectional shrinkage,numerical simulation and experimental method were adopted to analyze single wedge rolling and second wedge rolling method.
针对用楔横轧工艺生产具有大断面收缩率特点的汽车变速箱中间轴毛坯所存在的产品质量问题,利用数值模拟与实轧试验对汽车变速箱中间轴毛坯一次楔成形和二次楔成形进行了分析研究,发现采用一次楔成形方法加工汽车变速箱中间轴毛坯,轧件不易发生弯曲,中间断面收缩率最大处没有发生缩颈现象,心部质量也较二次楔成形好。
