Open-Die Fast-Forging Press Hydraulic System with Rapid Accumulator Discharge

With the advancement of industry, the dimensions and weights of forgings have been steadily increasing. Consequently, it has become necessary to reduce the installed power rating of free‑forging presses. Building on the conventional use of accumulator systems as balancing devices in free‑forging presses, this approach seeks to lower the installed power by increasing the volume of the accumulator system—particularly in large‑tonnage free‑forging presses, where deploying multiple accumulator‑based power sources as the primary pressure‑generating mechanism is increasingly essential.
