揿钮是一种日用小商品,体积较小,它由锌合金皮和黄铜絲制成。由于它是面底配合使用,因此面子生产的要求此较精确,尤其是嵌簧要求平正,卷边要求均匀。揿钮面子(见图1)在1958年前,从原料到成品,从落料拉伸、制弹簧、嵌簧卷边,都是手工操作,劳动强度高,产量低,质量不好,而且给操作工人带来许多不便。1959年,上海金属制品厂将手工制造揿钮的三个主要工序——落料拉伸、制弹簧、嵌簧卷边,用机械动作联合起来,初步革新成功揿钮面子联合机。当时由于部分结构不太合理,特别是送料部件误差过大,不能正常生产。我厂在上海金属制品厂革新的基础上,对送料部件进行了改革,经过多次试验,解决了这个关键部件,使联合机迅速投入生产。后来为了适应多规格
Push button is a daily commodity, smaller, it is made of zinc alloy and brass wire. Because it is used with the bottom of the face, so the face of the production requirements of this more accurate, especially the requirements of flat spring, curling requirements uniform. 19 button face (see Figure 1) Before 1958, from raw materials to finished products, stretching from the blanking, the system spring, spring crimp, are manual, high labor intensity, low yield, poor quality, but also to There are many inconveniences to workers. In 1959, Shanghai Metal Products Factory will be hand-made push button three main processes - blanking stretch, the system spring, spring crimp, combined with mechanical action, the initial success of the successful innovation 揿 button face sub-machine. At that time, due to part of the structure is not reasonable, especially the error of feeding parts is too large, can not be normal production. Based on the innovation of Shanghai Metal Products Factory, our factory has carried on the reform to the feeding parts. After many tests, this key part has been solved and the joint machine has been put into production quickly. Later in order to adapt to more specifications
