Most four column hydraulic presses are equipped with ejection cylinder. This is because during the machining process of hydraulic press, a part is needed to help take the product out of the mold, and the ejection cylinder plays this role.
In the past, there were a lot of customers who consulted on the Internet. When they asked whether they needed to eject the cylinder, many of them didn't know the function of the ejection cylinder. So let's introduce:
Most four column hydraulic presses are equipped with ejection cylinder. This is because during the machining process of hydraulic press, a part is needed to help take the product out of the mold, and the ejection cylinder plays this role.
To put it simply, the ejector cylinder plays a demoulding role in the four column hydraulic press, which ejects the workpiece from the concave mold. However, as the ejection cylinder is also an important part and has high cost, the four column hydraulic press with ejection cylinder is a little more expensive than the ordinary hydraulic press, which should be understood by most people.
The working process of the four column hydraulic top cylinder is also very simple. When the main cylinder of the hydraulic press stops moving, the operator presses the ejection button, the corresponding electromagnet is powered on, and the cartridge valve is opened. The hydraulic oil enters the lower chamber of the ejection cylinder through the cartridge valve, and the oil in the upper chamber flows back to the oil tank. The workpiece is ejected, and the ejected cylinder must be returned after ejection; Then, the operator of the four column hydraulic press presses the return button, the electromagnet loses power, and opens the cartridge valve. The hydraulic oil enters the upper chamber of the ejector cylinder, and the oil in the lower chamber flows back to the oil tank, forming a circulation system to maintain the continuous movement of the four column hydraulic press.
Now we all know that the work of four column hydraulic top cylinder is very simple, ejection and return, but the ejection cylinder movement can only start after the main cylinder movement of the hydraulic press is completed. The two movements are closely related, otherwise it will cause abnormal or safety accidents.
