The invention provides a metal packaging hydraulic machine hydraulic control system. The system comprises a plurality of oil pumps, wherein every two oil pumps are connected with two main shafts of adouble-shaft-extension motor correspondingly and provide hydraulic power, the oil pumps are connected with an oil tank through an oil filter, oil outlets of the oil pumps are connected with a plug-invalve group through a control valve group, a plurality of different plug-in valve group outlets are shared by the plug-in valve group, and the different plug-in valve group outlets are connected witha main pressure oil cylinder, a side pressure oil cylinder, a gland oil cylinder and an auxiliary oil cylinder of a packaging machine correspondingly and control corresponding packing actions. The system solves the problems that in the case of an existing metal packaging hydraulic machine system, the manufacturing period of a valve body is long, the difficulty is large, the operation impact is large, meanwhile, the tube layout is tedious, and the equipment cost is high.
