Abstract: To reduce the energy consumption of hydraulic press, an energy-saving partition control method was proposed. Several hydraulic presses were grouped to share the only drive system which was partitioned into several regions corresponding to hydraulic press operations named drive zone. The same operations of different hydraulic presses were carried out with the drive of the same drive zone. The output power of each drive unit matched the consumed power of the operations corresponding to the drive unit after energy efficiency optimization. The scheduling method of hydraulic press group was analyzed to ensure that different hydraulic presses in a group shared a drive zone in different time after the adjustment of working beat. The working processes of hydraulic press group were tested and analyzed. The results show that the energy consumption reduces by 40%, and the efficiency of a single hydraulic press increases by 13.3%.
