FORGING TOOL FOR THE MANUFACTURE OF A SHAPED ROLLED RING, NOTABLY FOR THE MANUFACTURE OF A TURBOMACHINE DISC

摘要

Mandrels (1, 2) for the rolling of a ring (7) comprise impressions (5, 6) to accommodate the ring, which impressions have fillet radii where the various faces meet, so as to avoid the creation of sharp corners on the rolled ring (7) and the accidental formation of cracks.
