Abstract (en)
[origin: US4831864A] In a forging machine, each ram is the piston or cylinder of a piston-cylinder hydraulic unit and the other component of the unit is attached to the forging machine frame and can be moved to adjust the ram stroke position. The piston or cylinder which constitutes the ram is guided directly in the machine frame to minimize play in the guidance of the ram component.
