标准件螺丝是任何机器上不可缺少的通用件,我厂所用数量相当大;每月约需5万只左右。过去是将元钢直接在车床和铣床上加工,既费料,效率又低。以后虽改为先锻制毛坯,后切削加工。但由于锻模结构不好,两火才锻制一个。同时取料很不方便效率仍然很低。在58年技术革命的高潮中我厂冷锻车间技术人员与工人相结合设计了一套用在摩擦压床上的自动退料热压模,压床滑块一次行程就可锻制一个螺丝。加工余量小,材料燃料消耗少,节省人工,得到高效率的生产。
Standard parts screws are indispensable for any machine on the common parts, I use a considerable number of plants; about 50,000 per month or so. The past is the yuan steel directly in the lathe and milling machine processing, both material, low efficiency. Although later changed to forging rough, after cutting. However, due to bad forging die structure, two fire before forging one. At the same time very inconvenient to reclaim the efficiency is still low. At the climax of 58 years of technological revolution, the technicians and workers of our factory cold forging workshop designed a set of automatic hot stamping die for pressing on the friction press. The machining allowance is small, the fuel consumption of the material is less, the labor is saved, and the high-efficiency production is obtained.
