20MN Two-Column Open Die Forging Press

Description

LS Heavy Industry Engineering Co., Ltd. 20MN pull-down hydraulic forging presses with two rectangular columns are directly oil-hydraulically driven. They offer a high forging speed and better visibility of the forging area for operator.

They have a casting mono-block frame ensuring a high eccentric load resistance and structure rigidity. The casting frame is also designed to have a low working stress, thus a high level of forging accuracy. All hydraulic cylinders and hydraulic stations including pumps, motors, tanks, valves, pipes are arranged under the floor. The presses can be installed in the low plant building.

The frame with low gravity center ensures a very small displacement under eccentric loading, it is also free of vibration during high speed forging work. Together with our technology in controlling proportional servo cartridge valve and replenishing & relief valve station, and special pipeline design, the sustainable high performance forging work is easily available.
