Presses can be driven mechanically or hydraulically. Water hydraulics has been used for forging presses for hundreds of years. Today, hydraulic presses are typically operated with pressures up to 300 bar. The required supply pressure is generated by an electric driven high pressure reciprocating pump. Compared to mechanical presses, hydraulic presses are easier to prepare and are particularly suitable for pulling operations, as the maximum force is available over the entire stroke length.
The hydraulic press drive is a high performance application. Pumps can be used in two ways. Very simple and inexpensive systems are those in which the pumps are connected directly to the presses. There are no valves or reservoirs between the pressure sockets of the pump and the press.
Other drives work with storage tanks and compressed air. High-pressure pumps convey into a pressure vessel in which the compressed air serves as an energy store and the water or the water-oil emulsion serves as an energy source.
Water as hydraulic fluid offers numerous advantages. It is non-flammable, environmentally friendly, is available almost unrestrictedly and is relatively inexpensive. Hydraulic press drives result in low operating costs, work very efficiently and are economical.
Hydraulic press drives are widely used in industry because of their economic operation. They can be found, for example, in the following application areas:
