METHOD FOR MANUFACTURING WORKPIECE AND METHOD FOR MANUFACTURING LAMINATED CORE |
| 摘要 |
This disclosure relates to a method for manufacturing a workpiece for a segmented laminated core. This method includes (A) feeding a plate for processing drawn from a roll thereof to a progressive die and (B) stamping out a workpiece in the progressive die, the workpiece including a plurality of pieces aligned in the circumferential direction with a circumferential part. At the step (B), an overall portion configured to be each piece of the workpiece is displaced in the thickness direction of the plate for processing, with portions on both sides of the piece being fixed, to form at least one cutting line across a region configured to be the circumferential part. |
