摘要

46 mold drop without composing the rotor core production line 30 is an apparatus for manufacturing a ring core which is laminated while placing the ring-shaped divided core plates 12, 16 a plurality of shaping the ring core. A rotating mechanism 55 by a predetermined angle rotation of the split core plates 12, 16 are laminated, 46 mold drop without the inner guide member 62 which is disposed on the inner peripheral side of the split core plates 12, 16 are laminated in a ring and, and a outer guide member 58 disposed on the outer peripheral side of the split core plates (12, 16), while supporting the split core plates (12, 16) in one of the outer guide member 58 and the inner guide member 62 , I want to apply pressure to the split core plates (12, 16) on the other hand.
