Abstract: In order to solve the problems of high energy consumption for huge free forging hydraulic press, an open variable pump-controlled hydraulic system for oil hydraulic press was proposed. Firstly, combined with ADAMS and AMESim, a co-simulation platform of open variable pump-controlled hydraulic press system was built, and aiming at typical work modes, regular forging and fast forging, the control characteristics were studied by simulations. Secondly, based on 600kN forging hydraulic press experimental platform, control characteristics for the open variable pump-controlled hydraulic press with regular forging and fast forging was verified respectively by experiments, and compared with the simulation results. The simulation and experimental results approve that the open variable pump-controlled hydraulic press system can meet the technical requirements. For regular forging, it has a good performance about manipulation, low impact and stability. For fast forging, when the forging frequency is up to 80 times per minute, the position control accuracy is less than 1mm.
