摘要： A laminated iron core manufacturing method in a blanking die apparatus having multiple machining stations is provided. The method includes feeding a belt-shaped workpiece progressively in a longitudinal direction in the blanking die apparatus, operating cutting tools provided in the respective machining stations simultaneously to perform predetermined blanking operations on the progressively fed workpiece and finally perform a contour blanking operation on the workpiece so as to form core pieces, and laminating the core pieces within or outside the blanking die apparatus to thereby manufacture a laminated iron core. An auxiliary cutting tool is operated to form a disposal hole by partly blanking a scrap forming area of the workpiece simultaneously with the operations of the cutting tools of the multiple machining stations, to thereby secure a load balance of the blanking die apparatus in the feeding direction.
