车轮中段冷扩涨模具的设计与应用

Designing and Application of Wheels Centre Band Cold Expanding Tool

从车轮部件制造的一个实际环节出发,应用新的冷扩涨模具冷扩工件,较好地解决了工件椭圆度大的问题,同时降低了材料成本,提高了生产效率。

From an actual aspect of manufacturing wheels parts, applying new expanding tool to coldly expand parts, present a new method to preferably solve the problem of parts biggish ellipse. At the same time this method reduces the manufacture cost and raises production efficieneies.
