ABSTRACT:
A frame for a large 50-500 kiloton forging press including a pair of spaced horizontally crossheads which are interconnected by left and right upright tie-rod assemblies. The crosshead and tie-rod assemblies are connected to one another by way of yoke shaped couplings which are disposed around each end region of the upper and lower crossheads. The tie-rod assemblies which are constructed of a plurality of overlapping elongated plates are pivotally connected to the couplings. The absence of link pins for connecting the tie-rods and crossheads directly to one another improves the distribution of stresses in the frame of the forging press. Apart from the above, plates of the tie-rods are fabricated in sections which are interlinked by suitable link plates to produce sufficiently long tie-rods. The plates of the tie-rods are provided with more than one linking position to the crossheads to allow adjustment of the size of the daylight of the forging press.
