我队山地机掘自到胡家峪改用小型压风机后,设备方面比从前简化了,符合了机掘轻便化的原则,如锻钎设备没有了,但我们全用合金钎头凿岩,还需压钎尾,怎么解决好呢?当时提出的办法有三种:一、是到有色金属公司去锻钎尾;二、是自己制造小型的压钎机(用人力摇动);三、是用焊接的办法焊好挡坯。 My team digging to the Hujianyuhu small air compressor, the equipment than the previous simplified, in line with the principle of digging machine light, such as forging brazing equipment is gone, but we all with the alloy bit drilling, the need to Pressure brazing tail, how to solve it? At that time, there are three ways proposed: First, to the non-ferrous metal companies forging the end of the shaving; Second, is their own manufacturing small brazing machine (with human power); Third, Ways welded good billet.
