Apparatus and method for manufacturing laminated iron core

Apparatus for manufacturing a laminated iron core formed by laminating and bonding a plurality of iron core laminates that are each formed by blanking a sheet steel strip into a prescribed shape, comprising:

• an upper metallic die assembly and a lower metallic die assembly opposing each other so as to blank the iron core laminates from the sheet steel strip that is conveyed in an intermittent manner;
• and
• an adhesive agent application unit configured to apply an adhesive agent to a prescribed area of the sheet steel strip corresponding to the iron core laminates;
• wherein the adhesive agent application unit is provided with a casing defining a plurality of adhesive agent storage chambers for storing the adhesive agent before the adhesive agent is applied to the prescribed area;
• wherein the casing is provided with a plurality of ejection orifices each communicating with a corresponding one of the adhesive agent storage chambers and configured to eject the adhesive agent, and
• wherein the laminated iron core is formed by iron core laminates including an annular or a circular section, and the adhesive agent storage chambers include at least a first storage chamber having an annular shape in plan view, and a second storage chamber having a larger annular shape in plan view and arranged concentrically to the first storage chamber.
