在工厂里,盘制直径很细而又很长的弹簧,是一项很困难的工作。我厂青年工人张孔维同志努力钻研,敢于创造,终于利用废料改进了一套盘制细长弹簧的工具,来盘制内径小到1公厘的细长弹簧,质量却很好,效率很高。这个工具的本体可以用手摇砂轮机,在原来装砂轮的地方装一只废齿轮,当作飞轮,使转动速度均匀,摇转轻快。弹簧心杆1,夹在钻夹头上。心杆的直径根据弹簧内径和钢丝强度,经过试验后决定。如果弹簧比较短,可以绕成一根长的,
In the factory, it is a very difficult task to plate a very thin and long diameter spring. My factory worker Zhang Kongwei young hard work to study, dare to create, and finally the use of waste to improve a set of slender spring disk tools to plate diameter as small as 1 mm slender spring, the quality is good, high efficiency. The body of this tool can use a hand-wheel grinder, a waste gear installed in place of the original wheel, as a flywheel, so that the rotation speed, shake light. Spring mandrel 1, caught in the drill chuck. Core diameter according to the diameter of the spring and wire strength, after the test decision. If the spring is relatively short, can be wound into a long,
