英文摘要：

A new saving-energy fast forging hydraulic press using accumulator was presented for the problem of power waste during forging process. The method of accumulator design and choice were offered, the model of proportional cartridge and accumulator were found, then the mathematical model of the whole fast forging circuit was found and simulated. The results show that the fast forging hydraulic press using accumulator performs perfect. Finally, based on the fast forging press test using accumulator, the model validity and feasibility of this fast forging circuit were validated.
