630-ton four-column hydraulic press China manufacturer

630-ton four-column hydraulic press machine China manufacturer. A hydraulic press is a machine that uses liquid as the working medium and is made according to Pascal's principle to transfer energy to realize various processes. The hydraulic press generally consists of three parts: the machine (host), the power system and the hydraulic control system. Hydraulic presses are classified into valve hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses.

Working principle

The working principle of hydraulic press. The areas of the large and small plungers are S2 and S1, respectively, and the forces acting on the plungers are F2 and F1, respectively. According to Pascal's principle, the pressure of the closed liquid is equal everywhere, that is, F2/S2=F1/S1=p; F2=F1(S2/S1). Indicates the hydraulic gain. Like the mechanical gain, the force increases, but the work does not gain. Therefore, the moving distance of the large plunger is S1/S2 times the moving distance of the small plunger.

● Computer optimized design, 3-beam, 4-column structure, simple but with high performance price ratio.

● Cartridge valve integral unit equipped for hydraulic control system, reliable, durable and less hydraulic shock, with shorter connection pipeline and fewer releases points.

● Independent electrical control, reliable, audio-visual and convenient for maintenance.

● Centralized button control system, with adjustment, hand and semi-auto operation modes at operator's choice.

● Fixed stroke forming process or fixed pressure forming process selected through control panel, with pressure hold and time delay functions.

● The operating force, no-load traveling and, low-speed movement and travel range can be adjusted subject to technological requirements. The frame is entirely welded with steel plates and treated to relive stress by tempering.
