PROBLEM TO BE SOLVED: To provide a method for manufacturing a laminated iron core capable of manufacturing a laminated iron core in a comparatively short time by substantially making a rotated lamination time of a die for rotating and laminating a rotor core piece coincident with a rotated lamination time of a die for rotating and laminating a stator core piece and efficiently operating a metal-mold device having a plurality of punching processes.SOLUTION: In a method for manufacturing a laminated iron core comprising: passing a thin strip material 10 through a metal mold device having a plurality of stations (A)-(H); punching a rotor core piece 11 and a stator core piece 12 in first and second dies 22, respectively; and rotating and laminating a rotor core 23 and a stator core 24, a time t1 for rotating and laminating the rotor core 23 laminated in the first die 22 coincides with a time t2 for rotating and laminating the stator core 24 laminated in the second die 22 in an error range of ±10%. |
