What is a hydraulic press machine？

Hydraulic presses include hydraulic presses and hydraulic presses. The water-based liquid as the working medium is called the hydraulic press, and the oil as the working medium is called the hydraulic press.

The basic requirements of hydraulic presses for working medium are:
(1) Have suitable fluidity and low compressibility to improve the efficiency of the transmission;
(2) Can prevent rust;
(3) Good lubrication performance;
(4) Easy to seal;
(5) Stable performance, long-term work and no deterioration.

A hydraulic press is a machine that uses a hydraulic cylinder to generate a compressive force. It works by using a fluid, such as oil or water, to transmit the force from one end of the cylinder to the other. The fluid is pressurized by a pump, and the resulting force is applied to a piston, which then transfers the force to a piston rod. The piston rod is connected to a platen, which is the part of the press that holds the workpiece.

Some characteristics of hydraulic presses include:

High force: Hydraulic presses are capable of generating very high forces, typically much greater than those produced by mechanical or pneumatic presses.
Adjustable force: The force generated by a hydraulic press can be easily adjusted by changing the pressure of the fluid in the cylinder.
Versatility: Hydraulic presses can be used for a wide range of applications, including forging, stamping, bending, and straightening.
Efficiency: Because hydraulic presses use fluid to transmit force, they are typically more efficient than other types of presses.
Safety: Hydraulic presses are generally considered to be safer to operate than other types of presses because the force is applied gradually and can be easily controlled.

The specifications of the hydraulic press are generally expressed in the nominal working force (kN) or the nominal tonnage (ton). Most of the hydraulic presses for forging are hydraulic presses, and the tonnage is high. In order to reduce the size of the equipment, large forging hydraulic presses often use higher pressures (about 35 MPa), and sometimes ultra-high pressure of more than 100 MPa is also used. Hydraulic presses for other uses generally use a working pressure of 6 to 25 MPa. Hydraulic presses have a lower tonnage than hydraulic presses.
