The principle is the use of PASCAL's law of fluid pressure driven machinery, there are many kinds. Of course, the use is varied according to the need. Such as according to the transfer pressure of the type of liquid, there are two types of hydraulic press and hydraulic press.
Hydraulic press produces a large total pressure, often used in forging and stamping. Forging hydraulic press is divided into two kinds: die forging hydraulic press and free forging hydraulic press. Die forging hydraulic press to use mold, while free forging hydraulic press does not use mold.
Hydraulic press is a kind of liquid as the working medium, used to transfer energy to achieve various processes of the machine. Hydraulic press in addition to forging forming, can also be used for correcting, pressing, packing, pressing block and pressing plate. Hydraulic press includes hydraulic press and oil press. The water-based liquid as the working medium is called hydraulic press, and the oil as the working medium is called hydraulic press.
