锅炉管道工使用板牙人工套丝,劳动十分繁重。我厂锅炉职工学习兄弟单位的经验并结合自己的实践,试制了一种半自动套丝机,经过四年多的使用证明,革新的这种机械,简易可行,减轻了体力劳动,提高了工效,也避免了用手扳动板牙扭伤手臂和腰部的事故。 半自动套丝机的原理是模仿手工套 Boiler plumber use artificial silk sets, labor is very heavy. I boiler plant workers learn brothers experience and combined with their own practice, trial production of a semi-automatic threading machine, after more than four years of use proved that the reform of this machine, simple and feasible, reducing manual labor and improve work efficiency, It also avoids the accident of wrestling the arms and the waist with a wrench. Semi-automatic threading machine’s principle is to imitate handmade sets
