丝杠在机械制造中的应用是很广泛的,许多机器都或多或少用到丝杠在机床制造中丝杠更是它的关键性零件之一但过去丝杠生产多是用切削的办法,这样做即浪费很多金属,而且生产率又低,不能满足当前大量的生产的要求。我们吸取了苏联先进经验发挥敢想敢干的精神,冷轧出了螺距8公厘外径28公厘双头丝杠(图1,①)螺距4公厘,外径28公厘单头丝杠(图1,②)及螺距6.28公厘,外径47.5公厘单头丝杠。丝杠轧制是在简易钢球轧机上进行的(轧机的简易 Screw in the machinery manufacturing is very wide range of applications, many machines are more or less used lead screw in the machine tool screw is one of its key components but in the past lead screw production is mostly cutting method , Which is to waste a lot of metal, and low productivity, can not meet the current mass production requirements. We learned from the advanced experience of the Soviet Union to dare to do what we dare to do, cold-rolled out a 8-mm lead screw 28 mm outside diameter double-headed screw (Figure 1, ①) pitch 4 mm, an outer diameter of 28 mm monofilament Bar (Figure 1, ②) and pitch 6.28 mm, diameter 47.5 mm single head screw. Screw rolling is carried out on a simple ball mill (simple rolling mill
