环框起弧模具设计

Design of Arcing Die for Ring Frame

根据环框的结构特点,针对传统三棍卷板成形工艺中留下后期难以完全消除材料厚度的10~20倍直边,造成材料极大浪费等问题,提出环框起弧技术方案。使用三维建模软件对环框起弧模具结构进行实体建模,得到起弧模装配结构示意图,并进行了强度校核。通过试验得出当回弹系数取0.88时设计出的环框起弧模具,成形效果良好,能实现去除直线段的目的,降低了生产成本,为环框起弧模具设计提供有价值的参考。

Based on ring frame structure characteristics , through the three roll plate forming process the problem of 10-20 times material thickness of the straight edge waste is difficult to be eliminated, technical solutions of the ring frame arc die is presented. The arc die structure of the ring frame is modeled by the three-dimensional modeling software, and the sketch map of the arc die is obtained, the strength of the key components is checked with the finite element software. The forming is good when the resilience coefficient is 0.88, it can achieve the aim of right angle edge and reduce the production cast.
