齿轮的滚压塑性成形技术的研究现状

运用滚压成形技术进行齿轮塑性加工具有设备简单、刀具寿命长及效率高的特点,尤其对斜齿轮的成形加工,没有拔模问题。近年来,在国外该技术的研究与运用得到极大的重视。文章对这些研究成果进行介绍,主要内容为滚压成形方法、冷和热挤滚压成形时出现的问题及解决措施。期望能对认识滚压成形的内在规律有所帮助。

The situation of studying on techndogies of rolling plasticity forming for gears

The technologies of rolling plasticity forming contain three traits which one made of simple equipment, long life of cutter and sufficient efficiency. Especially, it needn't pull-out fitment for the sloping gears forming . Recently, it has been attached great importance to this technology in the foreign countries. The paper introduces achievements contain the method of rolling plasticity forming. The problems which are affected by cold press rolling and hot press rolling and the resolving method, which is anticipated to help to recognize the revelation of rolling plasticity forming .
