Energy-saving Methods for Hydraulic Presses Based on Energy Dissipation Analysis

Hydraulic presses are large energy consumers in metal forming processes. In order to reduce carbon intensity and improve the energy efficiency, the overall carbon emissions of hydraulic presses was firstly analyzed. For a series of intermediate energy conversions in working processes, it is essential to understand and identify the energy dissipation characteristics of the investigated presses. Then, some energy matching methods for hydraulic drive system and a group of hydraulic presses in manufacturing system were presented to implement energy reduction. Finally, the proposed methodology shows a great energy-saving potential in sheet metal forming hydraulic presses.
