The Working Environment Of C Frame Press

The use of liquid as a working medium to pass the pressure to produce a huge working force forging machinery. Hydraulic press in addition to forging forming, but also can be used for correction, press fit, packing, briquetting and pressure plate and so on. Hydraulic presses include hydraulic presses and hydraulic presses. Water-based liquid as the working medium known as the hydraulic press, oil as the working medium known as the hydraulic press. The specifications of the hydraulic press are generally expressed in terms of nominal working force (kilograms) or nominal tonnage (tonnes).C Frame Press

Forging hydraulic presses are mostly hydraulic press, tonnage higher. In order to reduce the size of equipment, large forging hydraulic press commonly used higher pressure (35 MPa or so), sometimes more than 100 MPa above the high pressure. Other uses of the hydraulic press generally use 6 to 25 MPa working pressure. Hydraulic tonnage is lower than hydraulic press.C Frame Press

The role of the working medium used in the hydraulic press is not only the delivery of pressure, but also to ensure that the working parts of the machine work sensitive, reliable, long life and less leakage. The basic requirements of the hydraulic press on the working medium are: ① have the appropriate mobility and low compressibility, in order to improve the efficiency of transmission; ② anti-rust; ③ good lubrication performance; ④ easy to seal; ⑤ stable performance, long-term work Without deterioration. The hydraulic machine was originally used as a working medium, and later used in the water by adding a small amount of emulsified oil from the emulsion to increase the lubrication and reduce corrosion.C Frame Press Late appeared in the mineral oil as the working medium of the hydraulic machine. The oil has good lubricity, corrosion resistance and moderate viscosity, which is beneficial to improve the performance of hydraulic press. The second half of the 20th century, the emergence of a new type of water-based emulsion, the emulsified form is "water", rather than the original "oil." "Oil-in-water" emulsion of the external phase of the oil, its lubrication and corrosion resistance close to the oil, and little oil content, not easy to burn. But the water-based emulsion is more expensive, limiting its promotion.C Frame Press
