GSJ four column hydraulic press

Four column hydraulic press is a kind of mechanical equipment that uses hydraulic pressure of oil pump to process metal, plastic, rubber, wood, powder and other products. It is often used in pressing and pressing processes, such as: forging, stamping, cold extrusion, straightening, bending, flange, sheet metal deep drawing, powder metallurgy, press fit and so on. Its principle is the use of Pascal's law made of liquid pressure transmission machinery, many different types. Of course, the use is also varied according to needs. Such as the transfer of pressure by the type of liquid points, there are two major categories of hydraulic press and hydraulic press.

Four column hydraulic machine, also known as hydraulic machine, is the use of Pascal's law made of the use of liquid pressure transmission machinery, many types. Of course, the use is also varied according to needs. Such as the transfer of pressure by the type of liquid points, there are two major categories of hydraulic press and hydraulic press. Hydraulic press machine produces total pressure is big, commonly used in forging and stamping. Forging hydraulic press is divided into forging hydraulic press and free forging hydraulic press two. Die forging hydraulic machine to use the mold, and free forging hydraulic press without mold. Made in China's first million tons of hydraulic press is free forging hydraulic press.

Four-column hydraulic press machine from the host and control agencies of the two major components. Hydraulic machine main part includes hydraulic cylinder, beam, column and liquid-filled devices. Power by the fuel tank, high-pressure pump, control systems, motors, pressure valves, directional valves and other components. The hydraulic press is suitable for the pressing process of plastic material. Such as powder molding, plastic molding, cold (hot) extrusion metal forming, sheet stretching and horizontal pressure, bending pressure, turn through, calibration and other processes. Four-column hydraulic press has independent power mechanism and electrical system. It adopts push-button centralized control and can realize adjustment, manual and semi-automatic operation.
