摘要
A forging press has a stationary cross head which carries a lower die, and a movable frame with an upper die carried in the part of the frame above the stationary cross head. A positioning piston/cylinder unit, operated by low pressure fluid, moves the frame to a predetermined position relative to the stationary cross head. The frame is then locked in position by pressurizing oppositely acting piston/cylinder units, and the upper die is moved to carry out a forging operation by a piston/cylinder unit located in the top of the frame and operated by high pressure fluid.
