摘要： In a method for manufacturing a laminated iron core from a thin sheet, the method includes coining the thin sheet from below to form a thinned bridge portion on an outer peripheral portion of an iron core piece, blanking the iron core piece from the thin sheet from above or below after forming the bridge portion, and laminating the iron core piece on another iron core piece to manufacture the laminated iron core.

摘要： In a method for manufacturing a laminated iron core from a thin sheet, the method includes coining the thin sheet from above to form a thinned bridge portion on an outer peripheral portion of an iron core piece, blanking the iron core piece downwardly from the thin sheet using a set of an outer-shape blanking punch and a die after forming the bridge portion, wherein the outer-shape blanking punch includes a projection portion fitted into the bridge portion when blanking, and laminating the iron core piece on another iron core piece to manufacture the laminated iron core.
