最近我分局在加工鑽粒鑽头时,利用了压力机冲压方鋼的方法来制作鑽头。这种方法除可直接制作鑽头外,同时,还可以用所剩余的毛坯料制作上开取粉管接手。采用这种方法所制作的鑽粒鑽头每个成本为19.92元,与过去无縫鋼管制作的鑽头比較每个鑽头可节約资金20.06元。加工方法是將方鋼(规格见表1,图1)放在模型中,用压力机冲压,结果即成图2所示的形状,(规格見表2)。切去实心部份 Recently, in the processing of drilling bits, I used a press to punch square steel to make drill bits. This method can be used not only to directly make a drill bit, but also to take over the remaining blank material to take over the powder tube to take over. The cost of drill bits made using this method is 19.92 yuan each, which can save 20.06 yuan per bit compared with the drill bits made from the previous seamless steel tubes. The processing method is to place square steel (specification shown in Table 1, Fig. 1) in the model and punch it with a press. The result is the shape shown in Fig. 2, (Specifications are shown in Table 2). Cut out the solid part
