In 1795, the British j. brammer used PASCAL’s principle to create a water press for packaging and pressing vegetable oils.
By the middle of the 19th century, Britain began to use hydraulic presses for forging. The hydraulic press gradually replaced the super-large steam hammer.
By the end of the 19th century, the United States had built 126,00T free-forging hydraulic presses.
Since then, the world has produced more than 20 sets of 10,000T free-forging hydraulic machines, including two made in China.
With the development and improvement of the electric high-pressure pump, the forging hydraulic press is developing towards a small tonnage.
After the 1950s, small rapid forging hydraulic press appeared, which could do the things equivalent to the work done by 3-5Ton forging hammer.
In the 1940s, Germany made a huge die-forging press of 18,000T. Since then, the world has produced 18 sets of 18,000T forging hydraulic machines, of which one made in China is 30,000T.
