Manufacturing apparatus of laminated iron core

Abstract

A manufacturing apparatus of a laminated iron core includes a progressive die, that presses an electrical steel sheet having a coating containing an adhesive that exhibits adhesive ability through heating, provided to a sheet surface thereof, to obtain a unit iron core; a lamination space in which the unit iron cores after being subjected to a final pressing step in the progressive die are laminated; and a heating unit that is disposed at an upper part of the lamination space and that heats 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.
