钢丝螺套的试制,主要分为拉制菱形钢丝和把这种钢丝绕制成螺套两大工艺。 我们和上海第二钢铁厂、上海中国弹簧厂等单位共同对钢丝螺套进行了研制。目前,拉轧的菱形钢丝规格有:t=0.5;0.7;0.8;1.0;1.25;1.5和2.0共7种。已用在某发动机上的螺套品种有:4×0.7;5×0.8;6×1.0;8×1.25;10×1.5;18×1.5;27×2和33×2共8种,见图1。现将试制过程中的情况分述如下。
Trial production of wire thread sets, mainly divided into drawn diamond wire and made of such steel wire around the two major sets of technology. We and the second Shanghai Iron and Steel Plant, Shanghai China Spring plant and other units of the common wire thread sets were developed. At present, the rolled diamond wire specifications are: t = 0.5; 0.7; 0.8; 1.0; 1.25; 1.5 and 2.0 total of 7 species. Has been used in an engine on the nut varieties are: 4 × 0.7; 5 × 0.8; 6 × 1.0; 8 × 1.25; 10 × 1.5; 18 × 1.5; 27 × 2 and 33 × 2 total of 8, see Figure 1 . Now the trial process of the situation are as follows.
