合金钻头是野外勘探队消耗较多的一种工具。当各修配间收到未镶銲硬质合金的圆钻头后，必须自己开水口并镶銲合金。一般修配间都用锯条来加工，这不但费工时。而成本也高，现华东地质局326队，在加工合金钻头时是利用冲模冲制，方法简便，也合乎加工质量要求。该工具係由四件构成（见图），①为冲模架子，在左下方有一方脚，插入锻工砧子的方形孔内；③为垫铁，用以支承冲模架子的另一端；②为 Alloy drill bit is a tool consumed by the field exploration team more. When the repair shop received unearthed cemented carbide round bit, you must open their own water and inlay welding alloy. The general repair with saw blade to process, which not only time-consuming work. The cost is high, now the East China Bureau of Geology 326 team, the processing of alloy drill punching is the use of punching, the method is simple, but also meet the processing quality requirements. The tool consists of four parts (see Figure), ① for the punch stand, one foot on the bottom left, into the square hole forging anvil; ③ for the horn to support the other end of the die stand; ② for
