近年来，我在从事钻杆接头加工工艺的设计与生产中，总结钻杆锁接头、接箍等铣削装置及设备存在的问题，结合金刚石钻进用钻杆接头孔小、螺纹为特殊梯形螺纹等特点，设计了一种专为加工钻杆接头的铣丝装置，现将其结构及有关参数介绍如下。一、旋风铣削螺纹原理旋风铣削螺纹，是螺纹加工中生产效率较高的一种方法，具有操作简单、产品质量稳定等优点，适用于大批量的螺纹件生产。图1为旋风铣削螺纹示意图。其主要切削过程
In recent years, I engaged in the design and production of drill pipe joint processing technology, summarize the existing problems such as the drill pipe joint, coupling and other milling devices and equipment, combined with diamond drill pipe joint hole is small, the thread is a special trapezoidal thread And other characteristics, designed a drill pipe joints for the milling device, now its structure and related parameters are described below. First, the whirlwind milling thread Tornado milling thread, thread production is a higher efficiency, with simple operation, product quality and other advantages of stability, suitable for large quantities of thread production. Figure 1 for the cyclone milling thread diagram. Its main cutting process
