ABSTRACT:
A method of forging track tractor rollers, which comprises busting of a billet to a preformed coned end and placing a split ring around the coned end of the busted and preformed billet, and inserting the same in a blocking die to form flanges by blocking against the split ring and removing the split ring and billet. When placed in a finishing die, the hollow of the roller is preformed by a displacement method which forces the metal into the flanges against the split ring.
