As an important technical means of modern mechanical equipment to achieve transmission and control, hydraulic technology has been widely used in various fields of the national economy, four-column hydraulic press is suitable for pressing various plastic materials, in the working process: The upper hydraulic cylinder drives the upper slider to achieve a series of action cycles of express down, slow pressure to the final position, and the lower hydraulic cylinder drives the slide block in the same way.
The four-column hydraulic press has an independent power mechanism and electrical system, and adopts centralized control by buttons, and the process action is controlled by relays, which can realize three operating modes of adjustment, manual and semi-automatic operation. The travel range of pressure, pressing speed, no-load rapid downward and deceleration can be adjusted according to the needs of the process, and can complete the two working modes of constant pressure and fixed range molding. The process of constant pressure molding has pressure holding, delay and automatic return action after pressing.
Compared with other transmission control technologies, the hydraulic technology of four-column hydraulic presses has a high energy density. Flexible and convenient configuration? Wide speed range? Smooth and fast work? Easy to control and overload protection? Easy to achieve automation and mechatronics integration? The system has many significant technical advantages, such as design, manufacture, convenient use and maintenance, so that it has become the basic technical composition of modern mechanical engineering and the basic technical elements of modern control engineering.
