A four-column hydraulic press is also called an oil press. There are many types of hydraulic presses. For example, according to the type of liquid that transmits pressure, there are two major categories: oil presses and hydraulic presses. The total pressure generated by hydraulic presses is relatively large and is often used for forging and stamping. Forging hydraulic presses are divided into die forging hydraulic presses and free forging hydraulic presses. Die forging hydraulic presses require dies, while free forging hydraulic presses do not. The first 10,000-ton hydraulic press manufactured in my country is a free forging hydraulic press. A four-column hydraulic press consists of two major parts: the main machine and the control mechanism. The main body of the hydraulic press includes a hydraulic cylinder, a crossbeam, a column and a liquid filling device, etc. The power mechanism is composed of an oil tank, a high-pressure pump, a control system, an electric motor, a pressure valve, a directional valve, etc. The hydraulic press is suitable for the pressing process of plastic materials, such as powder product molding, plastic product molding, cold or hot extrusion metal molding, thin plate stretching, and horizontal pressing, bending pressing, turning through, and correction.
