胶管接头的倒锥齿(如图1),我们常规的加工方法多采用车削的方法,这种方法效率低、劳动强度大,而且质量也不稳定.我们试验在Z28～8C滚丝机上,按要求设计出成型的辊轮(如图3).采取冷滚压的工艺方法,将所需要的管接头部分,在园柱表面上直接滚压成型,效果良好,大大地 Inverted bevel gear hose connector (Figure 1), we use more conventional turning methods, this method is inefficient, labor-intensive, but also the quality is not stable.We test the Z28 ~ 8C thread rolling machine, press the Requires the design of the molding roller (Figure 3) to take the cold rolling process, the required part of the pipe joints, directly on the cylindrical roller surface molding, the effect is good, greatly
