厚板铰链无芯卷圆工艺及模具设计

从影响卷圆的因素入手,详细分析介绍了两种卷圆的工艺方法和模具结构设计,特别强调应用预弯工序来减少卷圆工作量,这是厚板小内径制件进行无芯卷圆的一把钥匙,从而突破了相对卷圆直径d/t≥4的限置,扩大了厚板无芯卷圆的范围。

The Coreless Curling Process and Die Design for the Plate Hinge

This paper staring with the influence factors from the curling, detail analysis and introduction curling process and die design for two types of curling, in this paper, formed by pre-bending to reduce the workload of curling, this is a key for the thick plate to coreless curling, it is to break through restrictions of the d/t〉4 for the diameter of curling, and expand the scope of the coreless curling for plate hinge.
