      Introduction to Four Column Hydraulic Press

      A four column hydraulic press is a mechanical equipment that uses the static pressure of hydraulic oil transported by an oil pump to process products such as metal, plastic, rubber, wood, powder, etc. Its principle is to use Pascal's law to create a mechanical device that utilizes liquid pressure transmission, and there are many types. It is commonly used in pressing and forming processes, such as forging, stamping, cold extrusion, straightening, bending, flanging, thin plate deep drawing, powder metallurgy, press fitting, and so on.

      The four column hydraulic press consists of a main engine, an electric control mechanism, and a hydraulic system. The host part includes the body, main cylinder, ejector cylinder, and filling device, etc; The power mechanism consists of an oil tank, a high-pressure pump, a low-pressure control system, an electric motor, and various pressure valves and directional valves; The electrical device follows the prescribed action program of the hydraulic system, selects the prescribed working mode, and completes the prescribed process action cycle under the command of the signal; Under the control of electrical devices, the power mechanism converts, regulates, and delivers energy through pumps, oil cylinders, and various hydraulic valves, completing the cycle of various process actions.

      The four column hydraulic press has an independent power mechanism and electrical system, which adopts button centralized control and can achieve three operation modes: adjustment, manual and semi-automatic. The working pressure, pressing speed, no-load fast downward and deceleration upward circumference of the machine can be adjusted according to process needs, and can complete three process modes: ejection process, no ejection process, and stretching process.
