Laminated Core, And Manufacturing Apparatus And Manufacturing Method Therefor

Abstract: A manufacturing apparatus 100 comprises a punch 12, a punching die 14, a first holding part 16, a second holding part 18, and a heating part 20. A plurality of core sheets 1a are punched from a steel strip 1 by the punch 12 and the punching die 14, the plurality of punched core sheets 1a are pressed downward by the punch 12 while the outer peripheral parts of the plurality of core sheets 1a are pressed from the side by the first holding part 16, and the plurality of core sheets 1a being pressed downward by the punch 12 are heated by the heating part 20 while being held in the second holding part 18. The first holding part 16 holds the plurality of core sheets 1a at a temperature lower than the softening temperature of an adhesive layer 11b, and the heating part 20 heats the plurality of core sheets 1a held in the second holding part 18 to a temperature equal to or higher than the softening temperature.
