QQ 194535455 Abstract Hydraulic machine, also known as hydraulic machine, it is a by liquid static pressure to the processing of metal, plastic, rubber, wood powder and other products, machinery, usually host for the structure of the three beams and four columns, three four beam of the hydraulic machine structure is economical and practical, so it has a wide range of applications in machinery manufacturing. Hydraulic machine is a kind of using liquid pressure used for the transmission of mechanical energy, hydraulic control can be suitably used cartridge valve integrated system, stable operation, smooth process using repeated many times, the impact of hydraulic inertia is small, shortening the connecting pipe and the discharge distance between the dew point, or general hydraulic control two kinds of forms, they can be used for all kinds of plastic material pressure processing technology and molding technology, such as punching blanking, bending, flanging technology, sheet metal drawing technology etc.. Basic principle is by the oil pump to the hydraulic oil is transported to the integrated cartridge valve blocks among, through a variety of one-way valve and the overflow valve to hy
