我厂在制造电焊钳橄榄簧时,过去一直是用手工先绕成圆簧,然后用克丝钳收缩两头,使之变成橄榄形.制造一个需要10多分钟,而且劳动强度大,工人干1～2小时后就疲劳了.为了改善工人的劳动条件及提高生产效率,我厂制造了一台手动绕簧机.其结构和作用原理如下(见图). I plant in the manufacture of electric welding clamp olive spring, the past has been used in the first round around the spring, and then use Kesi shrink the two ends, so that it becomes olive-shaped to create a need more than 10 minutes, and labor-intensive, dry workers 1 to 2 hours after the fatigue in order to improve the working conditions of workers and improve production efficiency, I plant a manual winding machine. Its structure and principle of action is as follows (see photo).
