With the custom engineering of the hydraulics for an ultra-modern open-die forge press built by China’s Taiyuan Heavy Machinery Group, Bosch Rexroth has made its début in the field of mega-size forge presses.
The hydraulics for the press, which has a massive gripper arm and applies 80 MN of power to shape steel in ingots up to four metres thick, are extremely powerful, fast and precise. They operate at 70 strokes per minute at a tolerance of just one millimetre, while still meeting the Taiyuan Group’s demanding expectations regarding automation, energy efficiency and noise output.
Bosch Rexroth engineers worked closely with the Technical Laboratory for Presses in Lohr, Germany, and used MOSIHS software, a program developed by Rexroth for modular simulation of hydraulic systems, in the planning, simulation and engineering of the hydraulics.
The end result is that several type A4 pumps now move ten thousand litres of high pressure hydraulic fluid into the system each minute. Adjustable-displacement, axial-piston pumps with pressure regulation and proportional volume adjustment make for high energy efficiency, while the entire system is under the command of an HNC motion control system. The machinery control directs the filler and regulator valves, which results in smooth interaction between the press and the manipulator.

Editor's Choice Hydraulic systems & components
Water hammer is a high-pressure surge or wave created by the kinetic energy of moving fluid when it is rapidly forced to stop or change direction, altering the liquid’s velocity. The progression of the water hammer shockwave needs to be detained and slowed before reaching the instrument sensor. SA Gauge manufactures several such devices in order to achieve this.
