PROBLEM TO BE SOLVED: To provide a method for rotating and laminating a laminated core, in which rotation and lamination are applied without stopping any reciprocal movement of a slide. SOLUTION: A sub slide 10 movable at the different timing from that of a slide 3 is arranged on the slide 3 of a press machine 1. A new intermediate laminated core K1 is formed by punching an iron core piece T out of a coil material W by continuous reciprocal movement of the slide 3, and at the same time, calking the punched iron core piece with the previously punched iron core piece T, and laminating the calked sets of the predetermined number. While forming the new intermediate laminated core K1, the previously laminated intermediate laminated core K2 is turned by the predetermined angle by a rotation-and-lamination driving device 20. A composite intermediate laminated core is formed by calking the new intermediate laminated core K1 pushed out by the sub slide 10 to the previous intermediate laminated core K2 which is turned by the predetermined angle. The new intermediate laminated cores K1 of the predetermined number are rotated and laminated to form one complete laminated core K. COPYRIGHT: (C)2011,JPO&INPIT |
