Four-column hydraulic press is a kind of mechanical equipment that uses the static pressure of hydraulic oil delivered by the oil pump to process metal, plastic, rubber, wood, powder and other products. It is often used in pressing process and pressing forming process, such as: forging, stamping, cold extrusion, straightening, bending, flanging, sheet drawing, powder metallurgy, press fitting, etc.
The 4 post hydraulic press is a machine made by Pascal’s law that uses liquid pressure transmission. The four-column hydraulic press machine produced by Zhengxi hydraulic press factory adopts a three-beam and four-column structure, which is simple, economical and practical. The hydraulic control adopts the cartridge valve integrated system, which has reliable action, long service life, small hydraulic impact, and reduces continuous pipelines and leakage points. It is a trustworthy machine.
Working Principle Of Four Column Hydraulic Press Machine
The four post hydraulic press uses a hydraulic pump to convert the mechanical energy of the prime mover into the pressure energy of the liquid through the hydraulic control system. Energy is transferred through changes in the pressure energy of the liquid. After passing through various control valves and hydraulic control pipelines, it enters the oil cylinder. Push the master cylinder fixed on the upper beam to drive the upper and lower movable beams to move back and forth. Guided by four columns, the upper and lower molds are closed to press the required workpieces. Then use the ejector cylinder to eject the pressed workpiece.
