Abstract: This disclosure relates to a method for manufacturing a segmented laminated core. 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.

Abstract: A heat-treatment apparatus includes a casing, a loader which loads a workpiece to an inner part of the casing in order to apply a heat-treatment to the workpiece, and a canopy surface provided in the casing to cover the workpiece. The canopy surface includes a slope way with a sectional configuration where the canopy surface is cut on a plane vertical to a conveying direction of the workpiece inside the casing. The slope way includes a highest point and a downward inclined surface extending from the highest point to an outside of a zone between a perpendicular line extending from a left end of the workpiece and a perpendicular line extending from a right end of the workpiece.
