Abstract
A forging press and method of forging to enable workpieces of exceptionally large diameter to be forged. The invention is an improvement over a press and method disclosed in an earlier patent in which a rectangular set of top dies is used with a circular set of bottom dies, and the bottom dies are indexed through a pattern of arcs to move a workpiece successively to positions in which it is forged throughout its area. The present invention utilizes a set of bottom dies which is of larger diameter than that of the indexing means and has overhanging edge portions. These portions are additionally supported at diametrically opposed locations where the force of the top dies is absorbed.
