Four-column hydraulic press

Four-column hydraulic press

 The four-column hydraulic press is a mechanical device that uses oil pump to deliver static pressure of hydraulic oil to process metal, plastic, rubber, wood, powder and other products. It is commonly used in pressing and press forming processes.Such as: forging, stamping, cold extrusion, straight, bending, flanging, sheet stretching, powder metallurgy, press fitting and so on. Its principle is that there are many kinds of machines made of Pascal's law that use hydraulic power transmission. Use is also varied according to needs.

●The four-column hydraulic press is also called the hydraulic press. If it is divided according to the type of liquid that transmits the pressure, there are two types of hydraulic presses and hydraulic presses. The hydraulic press produces a large total pressure and is often used for forging and stamping.The four-column hydraulic press consists of two parts: the main unit and the control unit. The main part of the hydraulic machine includes hydraulic cylinders, beams, columns and liquid filling devices.The power mechanism consists of a fuel tank, a high pressure pump, a control system, an electric motor, a pressure valve, and a directional valve. The hydraulic press is used in a pressing process for plastic materials. The four-column hydraulic press has an independent power mechanism and electrical system. It is controlled by buttons and can be adjusted, manual and semi-automatic.

●The hydraulic drive system of the four-column hydraulic press consists of a power mechanism, a control mechanism, an actuator, an auxiliary mechanism and a working medium. The power mechanism usually uses an oil pump as the power mechanism, and is generally a product type oil pump.In order to meet the requirements of the speed of the actuator, an oil pump or multiple oil pumps are used. Low-pressure gear pump; medium-pressure vane pump; high-pressure piston pump.
