摘要： There is provided a method for manufacturing a laminated iron core. The method includes receiving a plurality of block iron cores which are temporarily laminated and ejected from a die, each block iron core being formed by laminating a plurality of iron core pieces that are blanked from a thin plate workpiece using the die, individually separating the temporarily laminated block iron cores by a block iron core separating unit, and rotating and laminating each of the separated block iron cores by a rotating and laminating unit in order different from order of lamination of the temporarily laminated block iron cores before separation in a place different from a location of the die.

摘要： A method of manufacturing a laminated iron core includes extruding resins from a plurality of plungers toward a plurality of through holes extending from an upper surface to a lower surface of a laminated body formed of a plurality of electromagnetic steel plates to fill the plurality of through holes with the resins. The plurality of plungers are mutually independent and an extrusion amount of the resin is controlled for each plunger.
