梅山铁矿矿石十分坚韧,硬度f=12～16,并且多蜂窝状溶洞和裂隙,凿岩条件恶劣,钎具消耗量大。仅采矿台车YG80凿岩机用的φ52十字钎头,每年就要制作近万个。传统的方法是采用机械加工工艺,包括下料、锻、车、铣、钻、波形螺纹加工及热处理等12道工序。由于机加工工序繁多,不仅生产周期长,成本高,而且经常因规格、质量不合格,给使用带来困难。因此,每年都消耗大量的优质钢材。为解决这一矛盾,我矿机修厂风动车间精
Meishan iron ore is very tough, hardness f = 12 ~ 16, and more honeycomb cave and fissure, drilling conditions harsh, large amount of solder consumption. Only mining trolley YG80 drill with φ52 cross bit, every year to make nearly ten thousand. The traditional method is the use of mechanical processing technology, including cutting, forging, car, milling, drilling, wave processing and heat treatment of 12 processes. Due to the large number of machining processes, not only the production cycle is long and the cost is high, but often it is difficult to use due to the unqualified specifications and quality. Therefore, a large amount of high quality steel is consumed every year. In order to solve this contradiction, mine mills repair workshop pneumatic workshop fine
