以前德州机床厂铸造车间冲天炉配料用电磁吸盘的电源和传感器导线,使用滑轮组处理吸盘起落的导线伸缩问题。后来,自制了弹簧引线装置,效果很好,经两年多使用,没有发生一次断线故障。具体制作方法如下:用φ6弹簧钢丝绕成约200mm 直径的螺旋弹簧,共绕40 Previous Texas Machine Tool Plant Cupola cupola ingredients with electromagnetic chuck power supply and sensor wires, the use of pulley group handle suction and pull the retractable wire problem. Later, self-made spring lead device, the effect is very good, after more than two years of use, there is no occurrence of a disconnection fault. Specific production methods are as follows: with φ6 spring wire wound into about 200mm diameter coil springs, a total of around 40
