The role of the hydraulic press?


Hydraulic press is a machine that uses liquid as the working medium to transfer energy to achieve a variety of processes. Hydraulic press in addition to forging forming, can also be used for correction, press assembly, packaging, pressing and pressing plate. Hydraulic press includes hydraulic press and hydraulic press. The water-based liquid as the working medium is called the hydraulic press, and the oil as the working medium is called the hydraulic press. The specifications of the hydraulic press are usually indicated by nominal working force (kN) or nominal tonnage (ton). Forging hydraulic press is mostly hydraulic press, high tonnage. In order to reduce the size of the equipment, large forging hydraulic presses are commonly used at higher pressures (about 35 mpa), and sometimes high pressures above 100 mpa are also adopted. Hydraulic presses for other purposes usually adopt a working pressure of 6 to 25 mpa. The tonnage of the hydraulic press is lower than that of the hydraulic press.

This equipment is especially suitable for bending, forming, flanging and other processes of central load parts, and can also be used for punching and blanking processing after the blanking buffer device, which is the product of Marine industry, pressure vessel industry, chemical industry and other industries.


It is used for drawing, turning, bending and stamping of sheet metal parts, and can also be used for general pressing process, and can increase punching buffer, punching material, moving table and other devices according to user needs.


In addition to being used for forging and forming, the three-beam and four-column hydraulic press can also be used for straightening, pressing, packing, pressing and platen.


It can also be used for the pressing process of shaft parts, the calibration, clamping, pressing process of profiles, and the bending, disputing, shaping, embossing, covering, stretching, the pressing process of plastic materials, such as stamping, bending, flanging and thin drawing operations, and can also be engaged in the correction, pressing, plastic products and powder products pressing and forming operations. It is also known as hydraulic press because of its wide range of applications.

The working medium of the hydraulic press?


The role of the working medium used in the hydraulic press is not only to transfer pressure, but also to ensure that the working parts of the machine are sensitive, reliable, long life and less leakage. The basic requirements of the hydraulic press for the working medium are: (1) appropriate fluidity and low compressibility to improve the efficiency of the transmission; ② can prevent corrosion; ③ Has good lubrication performance; ④ Easy to seal; ⑤ Stable performance, long-term work without deterioration. The hydraulic press uses water as the working medium, and then uses the emulsion made of a small amount of emulsified oil in the water to increase lubricity and reduce rust. In the late 19th century, the oil press with mineral oil as the working medium appeared. The oil has good lubricity, corrosion resistance and moderate viscosity, which is conducive to improving the performance of the hydraulic press. In the second half of the 20th century, a new type of water-based emulsion appeared, and its emulsification form was "oil-in-water" rather than the original "oil-in-water". The outer phase of the "water-in-oil" emulsion is oil, and its lubricity and corrosion resistance are close to oil, and the oil content is very small, and it is not easy to burn. However, the price of water-based emulsion is expensive, which limits its popularization.
