Hydraulic transmission system of four-column hydraulic press

Hydraulic transmission system of four-column hydraulic press

The four-column hydraulic press is an oil pump that delivers the hydraulic oil to the integrated cartridge valve block, and distributes the hydraulic oil to the upper or lower chamber of the cylinder through each one-way valve and relief valve. Under the action of high-pressure oil, the cylinder is moved. Hydraulic press It is a device that uses liquid to transmit pressure. Liquids obey Pascal's law when they transmit pressure in a closed container.

The hydraulic transmission system of the four-column hydraulic press consists of a power mechanism, a control mechanism, an executive mechanism, an auxiliary mechanism and a working medium. a The power mechanism usually uses an oil pump as the power mechanism, generally an accumulating oil pump. In order to meet the requirements of the movement speed of the actuator, choose one oil pump or multiple oil pumps. 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, and also used for pressing of powder products, grinding wheels, bakelite and resin thermosetting products.

The four-column hydraulic press is simple, economical and practical. The exterior adopts an octagonal shape. The control electrical box adopts two kinds of glass door, PLC computer control or ordinary electrical appliances, with reliable operation, reliable operation, intuitive action and convenient maintenance. Independent buttons for centralized control. It has two operation modes: adjustment and single-hand cycle. The hydraulic control can use the integrated system of the cartridge valve, which has reliable action, long service life, small hydraulic impact, and reduces the connection pipeline and leakage point, or two kinds of ordinary hydraulic control. The four-column hydraulic press has a wide range of versatility. It is suitable for processing and forming of various plastic materials, such as extrusion, bending, hemming, stretching, etc. It can also be used for pressing and forming of various plastic and powder products. In addition, it can also be used for product calibration, press fitting and shaping.
