ABSTRACT:
A forging machine has a machine frame (1), radial forging rams (2) each adapted to carry a die (5), distributed angularly in a common working plane around the system axis (5); radial pressure-fluid piston (12) and cylinder (11) units on the machine frame, each with its cylinder forming or connected to a respective ram and having a stroke corresponding to the required ram stroke; and crossheads (15) mounted adjustably on the machine frame and each supporting the piston of a respective piston and cylinder unit. The stroke position of each ram is adjustable by adjustment of the crosshead towards and away from the system axis. A flange (19) is provided on each cylinder (11) and, a ring (17) extends around each ram, at the radially inner side of the flange (19), and is connected to the adjustable crosshead. Ram return piston and cylinder units (20,22) are disposed between the ring and flange.
