强化钻杆的螺纹连接,对提高机械岩心钻进的劳动生产率有很大潜力.勘探队广泛使用金刚石钻进对钻杆的质量提出了更高的要求.由于探寻最合适的钻杆结构,已制造出带有圆柱颈和圆锥螺纹(原文为圆柱螺纹和圆锥螺纹-校者)的联合式钻杆锁接头.以前用1K62型万能螺纹车床和9K14型管子车床加工螺纹需走刀5～6次.这项工作很复杂,要求车工特别细心.加工出的螺纹不是经常能达到高质量,有时有毛刺,裂纹和起鳞.由于在转数低的情况下使用硬质合金片的复杂性,车刀的寿命仍然短.这就需要创造一种能提高工件质量、减少劳动量的车螺纹新工艺.用这种方法加工螺纹不需特
Reinforcing the threaded connection of drill pipe has great potential to improve the productivity of mechanical core drilling.The team extensively uses diamond drilling to put forward higher requirements on the quality of drill pipe.Because of finding the most suitable drill pipe structure, To create a joint drill pipe with a cylindrical neck and taper thread (original cylindrical thread and taper thread - school). Previously used 1K62 universal thread lathe and 9K14-type pipe lathe thread machining required 5 to 6 times The work is complicated and requires the utmost care of the turner. The machined threads are not always of high quality, sometimes with glitches, cracks and scales. Due to the complexity of using carbide sheets at low rpm, The life of the knife is still short.This need to create a can improve the quality of the workpiece, reduce the amount of labor of the new thread technology.This method does not require special thread processing
