Original Abstract Submitted
An apparatus for manufacturing a laminated iron core includes a press device, circuitry, and a detecting unit. The press device includes a tab forming unit, a press-fit hole forming unit, and a punching unit. The punching unit is configured to use a die and a punch to punch out, from the workpiece, iron core pieces including press-fit holes and iron core pieces including tabs, stack the iron core pieces in the die to form a laminated body, and eject the laminated body through an ejection port. The detecting unit is configured to detect ejection of the laminated body through the ejection port. The circuitry is configured to determine that there is an anomaly in the press-fit hole forming unit when the detecting unit does not detect ejection of the laminated body within a predetermined detection time.
