Abstract:
A method for manufacturing a segmented laminated core is provided. This method includes (A) feeding a metal sheet to a progressive die, (B) stamping out workpieces in the progressive die, workpieces each include a plurality of pieces aligned in the circumferential direction with a circumferential part, and (C) fastening the workpieces together to obtain a segmented laminated core. The step (B) includes (b1) performing cutting-and-bending processing to form a slit line and a bending line across a region configured to be the circumferential part, (b2) returning by push-back a bent part that is a portion between the slit line and the bending line to an original position, and (b3) forming a swaged portion on the bent part. The step (C) includes (c1) fastening the workpieces by the swaged portion.
