Many people are asking, what is the difference between hydraulic presses and hydraulic presses? Let me explain in depth for everyone.
Hydraulic press is a machine that uses liquid as the working medium and is made according to the Pascal principle to transfer energy and achieve various processes. It is a machine that uses liquid static pressure to process metal, plastic, rubber, wood, powder and other products. It is commonly used in pressing and forming processes, such as forging, stamping, cold extrusion, straightening, bending, flipping, sheet drawing, powder metallurgy, pressing and so on.
According to the different working media, hydraulic presses can be divided into hydraulic presses and hydraulic presses. A water press is called a machine that uses water-based liquids as the working medium, and an oil press is called a machine that uses oil as the working medium. The two have a relationship between inclusion and inclusion;
Hydraulic presses for forging are mostly hydraulic presses with high tonnage. Large forging hydraulic presses often have a higher pressure (around 35 megapascals), and sometimes ultra-high pressures above 100 megapascals are also used. Hydraulic presses generally use a working pressure of 6-25 megapascals, and generally speaking, the tonnage of hydraulic presses is lower than that of hydraulic presses.
The original hydraulic presses were all hydraulic presses: in 1795, J. Bramer applied the Pascal principle to invent hydraulic presses, which were used for packaging, extracting vegetable oil, and so on. By the mid-19th century, hydraulic presses began to be used for forging, gradually replacing ultra large steam forging hammers. By the end of the 19th century, a 126000 kilonewton free forging hydraulic press was produced... Later, people found in practice that the performance of hydraulic oil was much better than that of water. Hydraulic oil not only has a suitable viscosity and good sealing effect, but also plays a very good lubricating role in the interior of the hydraulic system. Hydraulic precision components will not rust under long-term immersion of hydraulic oil, improving the service life and performance of the hydraulic system, The performance of water with added additives is not as good as that of oil. In addition, the compression ratio of hydraulic oil is smaller than that of water, and the working accuracy is higher, so it has strong stability. Currently, most of the presses used in the market are hydraulic presses, which are commonly referred to as hydraulic presses.
In summary, unless otherwise specified, the commonly referred to hydraulic press is an hydraulic press.
