我们参考西德汉堡SCHWARENBEK量具刃具厂和上海工具厂的有关资料,设计了三种外螺纹滚压头,可滚压螺纹的范围分别是M3～M5、M6～M10、M10～M22毫米,并试制了其中的大、小两种滚压头。经试用表明,用螺纹滚压头滚压外螺纹,其型面精度高,表面光洁度可达▽7,并可提高牙型的抗拉强度、抗疲劳能力及耐磨性,减少了加工工时,解决了我所外螺纹镀前加工缺少设备的问题。同时,为外螺纹的成形加工提供了一个新方法。外螺纹滚压头的结构如图所示。
We refer to the West Germany Hamburg SCHWARENBEK Measuring Tool and Cutting Tool Factory and Shanghai Tool Factory, the information on the design of the three kinds of male thread rolling head, the thread rolling range is M3 ~ M5, M6 ~ M10, M10 ~ M22 mm, and trial One of the big and small two rolling head. The trial shows that the use of thread rolling head rolling external thread, the profile of high precision, surface finish up to ▽ 7, and can improve the tooth-type tensile strength, fatigue resistance and wear resistance, reducing the working hours, Solve the lack of processing my external thread before plating equipment. At the same time, it provides a new method for the forming of the external thread. The structure of the male thread rolling head is shown in the figure.
