看了本刊1963年第1期“弯制拉力彈簧耳环的設备”一文后,感到手扳弯耳环夹具的結构复杂,精确度要求高。現将我厂的小型彈簧耳环的弯制工具作一簡介,供参考。一、工具的結构和特点图1所示的工具,結构簡单,制造容易,生产效率也較高。它可弯制英式单双耳环和单双旁側耳环等四种形式的彈簧耳环。弯出的彈簧耳环尺寸精度高,相互位置准确,式样美观,两端耳环間的尺寸誤差可保証在±0.5毫米內。

After reading the first issue of “The Equipment for Bending Tension Spring Earrings” in 1963, I found that the structure of the handgrip bending earring jig is complex and requires high precision. Now I plant a small spring earrings bending tools for a brief introduction for reference. First, the structure and characteristics of tools Figure 1 shows the tool, the structure is simple, easy to manufacture, production efficiency is higher. It can bend the British single and double earrings and single and double side earrings and other four kinds of spring earrings. Curved spring earrings with high dimensional accuracy, mutual positioning accuracy, beautiful appearance, the size of the error between the two ends of the earrings can be guaranteed within ± 0.5 mm.
