Abstract

Provided are a manufacturing device and a manufacturing method for a laminated core that can more reliably separate the laminated core from the group of core sheets and increase the punching speed of the core sheets. A manufacturing device 1 for a laminated core 4 according to the present invention is a manufacturing device 1 for a laminated core 4 in which core sheets 3 having a predetermined shape are formed by punching from a steel sheet 2 and a predetermined number of core sheets 3 are laminated and bonded, the manufacturing device 1 including: a punching portion 5 that punches out the core sheets 3 from the steel sheet 2; an adhesive application portion 6 that applies an adhesive to portions of the steel sheet 2 corresponding to the core sheets 3; a laminating portion 7 that laminates and bonds the core sheets 3 to which the adhesive has been applied to form a group of core sheets 30; and a separation portion 8 that bites into spaces between core sheets 3 adjacent to one another within the group of core sheets 30 to separate the laminated core 4 from the group of core sheets 30, wherein the laminating portion 7 includes a plurality of pairs of side pressure application portions 71 that apply a side pressure to the group of core sheets 30, each pair of side pressure application portions 71 is disposed to face each other with the group of core sheets 30 sandwiched therebetween, and at least one of the side pressure application portions 71 is configured to serve as the separation portion 8.
