Yz14e4-yf28-600/1000 is another large head forming hydraulic press produced by our company. This series of hydraulic press is mainly suitable for cold and hot forming pressing of pressure vessel head, and can also be used for various thick and thin steel plate pressing, folding, leveling process.

The machine adopts computer optimization design, replacing the big diameter hose with oil through the plunger hole and the idea of driving and controlling two motors with different requirements by a frequency converter are the first use in technology. Independent electrical control system, PLC, touch screen control, internal and external slider and ejector cylinder stroke detection are using high-precision displacement sensor, internal and external slider pressure detection, control using imported pressure sensor and imported proportional valve, with pressure, displacement digital display numerical control function, the top cylinder tray rotation frequency control, accurate tray positioning, equipment with secondary automatic stretching forming function. With the centralized control of buttons, there are two operation modes of adjustment and single cycle of both hands. Through the choice of moving operation panel, two molding processes of fixed range and fixed pressure can be realized. The operation of the machine is complicated and the conditions of signal interlock are many. Users are satisfied when they come to the factory for acceptance and test.
