摘要
介绍一种新型无模拉伸加工汽车后窥镜支杆的成形方法及生产工艺。通过对支杆无模拉伸变形机制的研究 ,分析了拉伸速度的变化规律 ,并建立了无模拉伸支杆的数学模型 ,实验证明 ,该模型结构简单、精确可靠 ,具有实用价值。
A sort of new-style dieless drawing shaped process of pole about automobile back-peep mirror and the method of manufacture technology introduced. From studying on the deformation mechanism of pole dieless drawing, the law of drawing speed has been analyzed. The mathematical model of dieless drawing for pole has been set up. It has been proved to true that the mathematical model is very simple, accurate, reliable, and practical through of experiment.
