生产过程概况汽车、拖拉机应用的起动机是我厂主要产品之一。每台起动机都装有不同型式、不同结构的单向离合器,它是起动机中的主要部件。多年来,单向离合器中的“内螺旋花键连接套”零件,我们一直采用老工艺——金切加工来生产,这种工艺方法效率低,劳动强度高,阻碍了生产的发展。我们也曾针对金切加工工艺作了好几次改进:单刀刨削内螺旋花键→单刀专用机床拉削→螺旋花键拉刀拉削等。但这些改进都没有根 Production process overview Automobile, tractor application of the starter is one of our main products. Each starter is equipped with different types, different structure of the one-way clutch, which is the starter in the main components. Over the years, the “internal helical spline connection” parts of one-way clutches have been manufactured using the old process - gold cutting, which is inefficient and labor-intensive, hindering the development of production. We have also made several improvements to the gold cutting process: single-point shaving spiral spline → single-purpose machine broaching → spiral spline broaching broaching. But none of these improvements are rooted
