圆形钢圈作为混凝土电杆的一个组成部分，在电杆相互间联接，以及电杆的固定中起着非常重要的作用。我厂传统的钢圈生产方式采用压力矫形，生产一个钢圈需多次冲压成型，受人为因素影响大，钢圈精度低，生产效率低，劳动强度高，因此生产方式落后。我厂科技人员在消化吸收... Round steel rings, as an integral part of concrete poles, play a very important role in the connection of poles to each other and to the fixation of poles. The traditional rim manufacturing method of our factory adopts pressure orthopedics. The production of a steel rim requires multiple stamping and forming, which is greatly affected by human factors. The rim precision is low, the production efficiency is low, and the labor intensity is high, so the production method is backward. Our factory science and technology personnel are digesting and absorbing...
