一,前言我厂是一个生产齿轮的专业厂。带有花键孔的齿轮品种、规格是较多的。产品质量上还有一些课题有待于介决。齿轮热处理后花键孔总有一些(或个别)要产生收缩变形。过去解决的办法,是用挤刀涨孔的方法进行修正。对变形较大的齿轮,往往涨孔多次也不易修正,有时甚至涨裂。同时,在成本上也不够经济,因挤刀都是用合金工具钢制造,修正淬硬齿轮,用不了多久就磨接报废·为了介决这一关键问题,我们决定采用近年来出现的一种新的工艺方法——电解加工。
I. INTRODUCTION Our factory is a professional factory producing gears. There are many types and specifications of gears with spline holes. There are still some issues to be resolved in product quality. There are always some (or some) shrinkage deformations in the spline holes after heat treatment. The solution to the problem in the past was to correct the hole with a cutter. For gears with large deformations, it is often difficult to correct the number of holes that have risen many times, and sometimes it even cracks. At the same time, it is also not economically cost-effective, because the squeegee is made of alloy tool steel, and the hardened gears are modified. It will take a long time to scrape and scrape. In order to mediate this critical issue, we decided to adopt a type that has emerged in recent years. New process method - electrolytic processing.
