Four column hydraulic press principle

Four-column hydraulic press working principle: four-column hydraulic press is an oil pump to the hydraulic oil delivery to the integrated cartridge valve block, through the various check valves and relief valves to the hydraulic oil distribution to the upper or lower chamber of the cylinder, under the action of high-pressure oil, so that the cylinder for movement.

Four-column hydraulic press is a kind of mechanical equipment that uses the static pressure of hydraulic oil delivered by oil pump to process metal, plastic, rubber, wood, powder and other products.

Widely used in pressing process and press molding process, such as: forging, stamping, cold extrusion, straightening, bending, flanging, sheet deep-drawing, powder metallurgy, press fitting and so on.

Column hydraulic press, also known as hydraulic press, is the use of Pascal's law made by the use of liquid pressure transmission machinery, there are many types. Of course, the use is also based on the need for a variety of different. For example, according to the type of liquid that transmits the pressure, there are two major types of hydraulic presses and hydraulic presses.
