METHOD AND APPARATUS OF MANUFACTURING LAMINATED IRON CORE |
| 摘要 |
A method of manufacturing a laminated iron core includes performing at least two kinds of selectively-actuated punching processes by actuating respective punching units to form a plurality of iron core pieces, each of the punching units being switchable between an active state or a non-active state, and caulking and laminating the plurality of iron core pieces to manufacture the laminated iron core. The selectively-actuated punching processes are performed in one operation by selectively actuating each of the punching units between the active state and the non-active state. |
