Manufacturing apparatus of laminated iron core

A manufacturing apparatus of a laminated iron core, the laminated iron core including unit iron cores that are pressed from an electrical steel sheet having a coating containing an adhesive that exhibits adhesive ability through heating, provided to a sheet surface of the electrical steel sheet, and laminated, the manufacturing apparatus comprising:

• a progressive die configured to press the electrical steel sheet having the coating containing the adhesive that exhibits adhesive ability through heating, provided to the sheet surface of the electrical steel sheet, to obtain a unit iron core, the electrical steel sheet being conveyed along a conveyor path, the progressive die disposed along the conveyor path;
• a lamination space configured to laminate the unit iron cores after being subjected to a final pressing step in the progressive die, the lamination space disposed downstream from the progressive die along the conveyor path;
• and
• a heating unit that is disposed at an upper part of the lamination space and is configured to heat the sheet surface of the unit iron core of an uppermost layer laminated in the lamination space, at a plurality of partial regions to make the unit iron core of the uppermost layer to be partially adhered to the unit iron core of a lower layer thereof at a plurality of regions the heating unit disposed downstream from the progressive die along the conveyor path.
