上海电表厂四车间职工制造的小型自动绕弹簧机,能自动绕制钢丝直径零点一五至零点四毫米的小型弹簧,不仅减轻了原来用手工绕弹簧的劳动强度,提高效率十七至二十倍,而且质量得到保证。改革后的自动绕弹簧机,利用滚轮送料和顶杆弯曲的原理,达到自动绕制的要求。绕制弹簧 The small automatic winding spring machine made by employees at the four-meter shop in Shanghai Electric Meter Factory can automatically wind small springs with a diameter of steel wire from 0:15 to 0:40 mm, which not only reduces the labor intensity of hand-wound springs but also increases the efficiency from 17 to Twenty times, and the quality is guaranteed. After the reform of the automatic around the spring machine, the use of roller feed and ejector principle of bending to achieve automatic winding requirements. Winding the spring
