摘要:
A method of forging track tractor rollers and other multi-flanged 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 stepped blocking die to form flanges by blocking against the split ring and the stepped die for one flange and between the top die on the other flange and removing the split ring and billet. When placed in a finishing die, the hollow of the roller is formed by a displacement method which forces the metal into the flanges against the split ring.
