How does the hydraulic press ejector cylinder work? The first step in the working process of the ejector cylinder is the workpiece ejector. The specific realization is that when the master cylinder stops moving in the return journey, press the ejector button, and the corresponding three electromagnets will get electricity, two of the cartridge valves will be opened, two of the hydraulic oil will enter the lower chamber of the ejector cylinder through the cartridge valve, and the oil in the upper chamber will flow back to the tank through the valve, and the workpiece will be ejector.
The second step is to return the ejector cylinder, first press the return button, the electromagnet loses power, the other electromagnets get power, the cartridge valve is opened, the hydraulic oil enters the upper chamber of the ejector cylinder through the valve, the oil in the lower chamber flows back to the tank through the valve, and the ejector cylinder returns. When these steps are completed, the next step is started, and then a circulatory system is formed to maintain the continuous movement of the four-column hydraulic press.
