Manual hydraulic pressSuitable for the pressing process of plastic materials, such as stamping, bending, flanging, thin stretching, etc., it can also be used for correction, pressing, plastic product and powder product pressing and forming. Economical, portable and convenient. The manual hydraulic power source can be manual or electric, with ultra-high pressure, ultra small size, easy to carry, simple operation, and wide application range. It has the advantages of beauty, small size, light weight, reasonable structure, stable performance, stable output pressure, and reliability.

The working principle of hydraulic press. The areas of the large and small plunger are S2 and S1, respectively, and the forces acting on the plunger are F2 and F1, respectively. According to Pascal's principle, the pressure of a sealed liquid is equal everywhere, that is, F2/S2=F1/S1=p; F2=F1(S2/S1)。 The gain effect of hydraulic pressure is the same as mechanical gain, where the force increases but the work does not increase. Therefore, the movement distance of the large plunger is S1/S2 times that of the small plunger.

The basic principle is that the oil pump delivers hydraulic oil to the integrated plug-in valve block, and distributes the hydraulic oil to the upper or lower chamber of the cylinder through various one-way valves and relief valves. Under the action of high-pressure oil, the cylinder moves 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. The hydraulic transmission system of a four column hydraulic press consists of a power mechanism, a control mechanism, an actuator, an auxiliary mechanism, and a working medium. The power mechanism usually uses an oil pump as the power mechanism, usually an integral oil pump. To meet the requirements of the actuator's movement speed, one or multiple oil pumps should be selected. Gear pump for low pressure (oil pressure less than 2.5MP); Medium pressure (oil pressure less than 6.3MP) blade pump; Use a plunger pump for high pressure (oil pressure less than 32.0MP). The pressure processing and forming of various plastic materials, such as extrusion, bending, deep drawing of stainless steel plates and cold pressing of metal parts, can also be used for the pressing of powder products, grinding wheels, glued laminated wood, and thermosetting resin products.

This equipment is particularly suitable for various processes such as bending, forming, and flanging of central load parts. When equipped with a punching buffer device, it can also be used for punching and material processing. It is a product in industries such as shipbuilding, pressure vessel, and chemical engineering.

Used for processes such as stretching, flipping, bending, and stamping of metal sheet parts, and can also be used for general pressing processes. Devices such as punching buffer, feeding, and moving worktable can be added according to user needs.

In addition to being used for forging and forming, the three beam four column hydraulic press can also be used for straightening, pressing, packaging, pressing blocks, and pressing plates.

It can also be used for the pressing process of shaft parts, the calibration, crimping, and installation process of profiles, as well as the bending, arguing, shaping, embossing, nesting, stretching, and plastic material pressing process of sheet parts, such as stamping, bending, flanging, thin stretching, etc. It can also be engaged in calibration, pressing, plastic product and powder product pressing and forming operations. Due to its wide range of applications, it is also known as a hydraulic press
