Ejection cylinder of four-column hydraulic press

The first step in the working process of the four-column hydraulic press is to eject the workpiece. The specific realization is that when the main cylinder stops moving, press the eject button, the corresponding 3 electromagnets are energized, and 2 of the cartridge valves are opened. The two hydraulic oils enter the lower chamber of the ejector cylinder through the valve cartridge valve, and the oil in the upper chamber flows back to the oil tank through the valve, and the workpiece is ejected. The second step is to return the ejector cylinder. First press the return button, the electromagnet is de-energized, the other electromagnets are energized, the cartridge valve is opened, the hydraulic oil enters the upper chamber of the ejector cylinder through the valve, and the oil in the lower chamber passes through the valve. The valve flows back to the tank, ejecting the cylinder back. When these steps are completed, the next step begins, and then a circulatory system is formed to maintain the continuous movement of the four-column hydraulic press.

In contrast, the movement process of the master cylinder of the four-column hydraulic press is more complicated and has many steps, but the working process of the ejector cylinder is very simple, only two steps, and the movement of the ejector cylinder occurs when the master cylinder movement is completed. After that, the working process of ejecting the cylinder is started, and the two can be said to be closely related.
