Since then, the world has produced 18 sets of 18,000T forging hydraulic machines, of which one made in China is 30,000T. In the 1940s, Germany made a huge die-forging press of 18,000T. With the development and improvement of the electric high-pressure pump, the forging hydraulic press is developing towards a small tonnage.Īfter the 1950s, small rapid forging hydraulic press appeared, which could do the things equivalent to the work done by 3-5Ton forging hammer. Since then, the world has produced more than 20 sets of 10,000T free-forging hydraulic machines, including two made in China (see Fig.4).
The hydraulic press gradually replaced the super-large steam hammer.īy the end of the 19th century, the United States had built 126,00T free-forging hydraulic presses. brammer used PASCAL’s principle to create a water press for packaging and pressing vegetable oils.īy the middle of the 19th century, Britain began to use hydraulic presses for forging. In the world, any country with a huge die-forging press is a powerful aviation industry. The 80,000-ton hydraulic press broke the world record held by the former Soviet Union for 51 years.ĭie forging press is mainly used to manufacture high strength titanium/aluminum alloy forgings in aerospace, nuclear power, petrochemical and other fields. There were 30,000 tons, 40,000 tons and 80,000 tons of die forging presses built in 2012 alone. Until the last two years, several huge presses were developed explosively. The Soviet Union built two huge 75, 000-ton die-forging presses around 1961.įrance bought a 65,000 ton die-forging press from the Soviet Union in 1976 and developed a 40,000 ton die-forging press in 2005 in cooperation with Germany.Ĭhina’s first 30, 000-ton die-forging press stalled for nearly 40 years after it was built in 1973. In 2001, another 40,000-ton die-forging press was built at the Shultz steel mill in California. The United States built two of the world’s largest 45,000 ton die-forging presses around 1955, which are still in use today. There are only a few countries in the world that can make such a hydraulic forging press.Ĭurrently, only China, the United States, Russia and France have more than 40,000 tons of die forging presses in the world. The giant die-forging hydraulic press is a national treasure class strategic equipment which symbolizes the strength of the heavy industry. The 80,000-ton die-forging hydraulic press is 27 meters high on the ground and 15 meters underground, with a total height of 42 meters and a total weight of 22,000 tons, which make it the most powerful and strongest hydraulic press in the world It is often used in pressing and pressing forming processes, such as forging press, stamping, cold extrusion, straightening, bending, flanging, sheet drawing, powder metallurgy, pressing, etc.
Hydraulic press machine (also known as hydraulic oil press) is a machine that makes use of the static pressure of the liquid to process metal, plastic, rubber, wood, powder products. Generally, the hydraulic press machine consists of three parts: the machine (mainframe), the power system and the hydraulic control system. The hydraulic press is a kind of machine which uses the liquid as a working medium to transfer energy based on PASCAL’s principle to realize various technique.
