Six-Position hydraulic punching machine is specially used for assembly of aluminum window; It can be used for the punching procedure of aluminum profile. Each combination mould collaborated with this equipment can accomplish many punching procedures; Punching process of doors and windows of various specifications can be realized through changing different station; Disk worktable is adopted with six stations; Six sets of moulds can be installed; Different moulds can be used at any time through turning the worktable, which greatly improves working efficiency. Five-cylinder hydraulic pressure punching machine is mainly used together with single mould and combination mould of aluminum alloy door and window series to finish the punching processing of all the holes and notches of various corresponding common profile and insulation profile. There is pressure compensating device equipped with the part of hydraulic power, i. e. The energy accumulator, to ensure that rated working pressure can be reached when five oil cylinders work at the same time. It is characterized by stable blanking, high speed and efficiency, pollution-free and high precession and possesses the function of automatic scrap discharge. The worktable is large and it is quick, convenient, safe and reliable to replace the mould.
