Because of the hydraulic system and the whole structure of the four-column press, it is now experienced in the new direction of the four-column press. With the development of the share servo technology, the stop position accuracy and speed control accuracy of the four-column press are higher and higher, and the hydraulic press tends to be carried out with high precision. High speed, high efficiency and low energy consumption improve the working efficiency of hydraulic press and reduce production cost. Active and intelligent, the high speed of microelectronic technology has provided abundant conditions for the initiative and intelligence of hydraulic press. The active diagnosis and adjustment of the system should be completed. Hydraulic components are integrated, standardized, and integrated hydraulic system reduces pipe connection and effectively prevents leakage and pollution.
