A hydraulic press is a machine that uses liquid as the working medium and is made according to Pascal's principle to transfer energy to realize various processes. The hydraulic press generally consists of three parts: the machine (host), the power system and the hydraulic control system. Hydraulic presses are classified into valve hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses. Hydraulic presses are often used in pressing processes and press forming processes, such as: forging, stamping, cold extrusion, straightening, bending, flanging, sheet drawing, powder metallurgy, press fitting, etc. The first 10,000-ton hydraulic press made in China is a free-forging hydraulic press.
Development history of hydraulic press:
In 1795, J. Brammer of the United Kingdom applied Pascal's principle to invent a hydraulic press for packing and pressing vegetable oil. By the middle of the 19th century, the British began to use the hydraulic press for forging, and the hydraulic press gradually replaced the super-large steam forging hammer. By the end of the 19th century, the United States made 126,000 kN free-forging hydraulic presses. Since then, more than 20 100,000 kN free-forging hydraulic presses have been manufactured around the world, of which 2 are made in China. With the emergence and improvement of electric high-pressure pumps, forging hydraulic presses are also developing in the direction of smaller tonnage. After the 1950s, small rapid forging hydraulic presses appeared, which can perform work equivalent to 30 to 50 kN forging hammers. In the 1940s, Germany made a giant die forging hydraulic press of 180,000 kN. Since then, 18 die forging hydraulic presses of more than 180,000 kN have been made in the world, of which one made in China is 300,000 kN.
Use of hydraulic press:
A hydraulic press is a machine that uses liquid as the working medium to transfer energy to realize various processes. In addition to forging and forming, hydraulic presses can also be used for straightening, pressing, packing, pressing blocks and pressing plates. Hydraulic presses include hydraulic presses and hydraulic presses. The water-based liquid as the working medium is called a hydraulic press, and the oil as the working medium is called a hydraulic press. The specifications of hydraulic presses are generally expressed in terms of nominal working force (kN) or nominal tonnage (tons). Forging hydraulic presses are mostly hydraulic presses with high tonnage. In order to reduce the size of the equipment, large forging hydraulic presses often use higher pressures (about 35 MPa), and sometimes ultra-high pressures above 100 MPa are also used. Hydraulic presses for other purposes generally use a working pressure of 6 to 25 MPa. The tonnage of the hydraulic press is lower than that of the hydraulic press.
