Hydraulic press is a machine that uses hydrostatic pressure to process products such as metal, plastic, rubber, wood, powder, etc. It is commonly used in pressing and forming processes, such as forging, stamping, cold extrusion, straightening, bending, flanging, thin plate deep drawing, powder metallurgy, press fitting, and so on.
Its principle is to use Pascal's law to create a mechanical device that utilizes liquid pressure transmission, and there are many types. Of course, the uses are also diverse according to needs.
A hydraulic press is a machine that uses liquid as the working medium to transfer energy and achieve various processes. Hydraulic presses can be used not only for forging and forming, but also for straightening, pressing, packaging, pressing blocks, and pressing plates. Hydraulic presses include hydraulic presses and hydraulic presses. A hydraulic press is called one that uses water-based liquid as the working medium, and one that uses oil as the working medium is called a hydraulic press. The specifications of hydraulic presses are generally expressed in nominal working force (kilonewtons) or nominal tonnage (tons). Most hydraulic presses used for forging are hydraulic presses with high tonnage. To reduce equipment size, large forging hydraulic presses commonly use higher pressures (around 35 megapascals), and sometimes even use ultra-high pressures above 100 megapascals. Hydraulic presses for other purposes generally use a working pressure of 6-25 megapascals. The tonnage of hydraulic press is lower than that of hydraulic press.
