Abstract

1276415 Forging GFM GES FUR FERTIGUNGSTECHIK UND MASCHINENBAU AG 20 Nov 1970 [30 Dec 1969] 55193/70 Heading B3H A forging machine comprises a pair of opposed rams or a set of four rams 3, 3a, 4, 4a each guided in spaced guides 6, 7 and driven on the working stroke by hydraulic actuators 8 and on the return stroke by an axial hydraulic actuator 9. The actuators are supplied from piston pump units 10, 11. In the ease with four rams each piston pump unit drives an adjacent pair of rams. Each unit comprises a pair of large pistons (12), (12a), Fig. 2 (not shown), axially aligned with a pair of small pistons 13, 13a. The large piston 12 supplies fluid to the actuators 8 of the ram 3 and the aligned small piston (13a) supplies fluid to the actuator 9 of the ram 3a. The pistons are driven by a pair of parallel shafts (14), (15) with eccentrics (16), (17). The eccentrics are 180 degrees out of phase to ensure that all the rams move synchronously. The piston pump units 10, 11 are driven from a common shaft 23.
