● Video

The four-column hydraulic press machine is an oil pump that transports hydraulic oil to the integrated cartridge valve block. The hydraulic oil is distributed to the upper or lower chamber of the cylinder through each check valve and relief valve, and the cylinder is moved by the high-pressure oil. A hydraulic press is a device that uses liquid to transmit pressure. When a liquid transfers pressure in a closed container, it follows Pascal's law.


●Composition

The four-column hydraulic press is composed of two parts: the host and the control mechanism. The main part of the hydraulic press includes hydraulic cylinders, beams, columns, and liquid filling devices. The power mechanism is composed of a fuel tank, a high-pressure pump, a control system, a motor, a pressure valve, a directional valve, and the like.

Hydraulic press

●Use

This hydraulic press is suitable for the pressing process of plastic materials. 

The four-column hydraulic press has an independent power mechanism and electrical system and adopts centralized control of buttons, which can realize three operation modes of adjustment, manual and semi-automatic.


●Features

The machine has an independent power mechanism and electrical system and adopts centralized control of buttons, which can realize three working modes of adjustment, manual and semi-automatic. The machine's working pressure, pressing speed, no-load fast down and deceleration stroke and range can be adjusted according to the process needs and can complete the ejection process. There can be three ejection processes, such as the ejection process and the stretching process. The process is constant pressure. Two process actions are available for constant pressure. The constant pressure molding process has ejection delay and automatic return after pressing.


●Introduction to a Hydraulic Press

Also known as Hydraulic machine using Pascal's law to make use of liquid pressure transmission machinery, there are many types. Of course, the users are also diverse as needed. Of course, the users are also diverse as needed. For example, according to the type of liquid that transmits the pressure, there are two types of hydraulic and hydraulic presses. The total pressure generated by the hydraulic press is large, and it is often used for forging and stamping. Forging hydraulic presses are divided into die forging hydraulic presses and free forging hydraulic presses.


●Working Principle

The hydraulic transmission system of a four-column hydraulic press is composed of a power mechanism, a control mechanism, an executive mechanism, an auxiliary mechanism, and a working medium. The power mechanism usually uses an oil pump as the power mechanism and is generally an integrated oil pump. To meet the requirements of the speed of the actuator, an oil pump or multiple oil pumps are selected. Gear pump for low pressure, oil pressure less than 2.5MP, vane pump for medium pressure, oil pressure less than 6.3MP, plunger pump for high pressure, oil pressure less than 32.0MP. Pressure processing and forming of various plastic materials, such as extrusion, bending, stretching of stainless steel plates and cold pressing of metal parts. It can also be used for pressing powder products, grinding wheels, bakelite, and resin thermosetting products.
