层叠铁心的制造方法和层叠铁心制造装置
摘要：
本发明提供一种层叠铁心的制造方法和层叠铁心制造装置，即使在形成与铁心薄板的中央开口连接的多个磁铁安装孔的情况下，也能够防止铁心薄板变形并进行稳定的铆接结合。在层叠铁心的制造方法中，构成为具有：形成磁铁安装孔（h1）的磁铁安装孔形成工序，所述磁铁安装孔（h1）在铁心薄板（2）的周向配置有多个，并在层叠后分别嵌装永久磁铁；在磁铁安装孔形成工序之前或之后，在铁心薄板形成外侧铆接计量孔（m1）和外侧铆接突起（m2）的铆接形成工序；在冲裁或半冲裁出与各磁铁安装孔的内缘（h1a）连接的中央开口区域（h3）后将其推回的推回工序；冲裁出铁心薄板的外形（h4）的外形冲裁工序；及将铁心薄板铆接结合而形成层叠体（3）的层叠工序。
摘要（英）：

Stable caulking combination can be performed while preventing transformation of a metal pin thin plate even if a plurality of magnet installation holes are connected to a central opening of the thin plate. A method for manufacturing a laminating metal pin includes a magnet installation hole forming step of forming a magnet installation hole (h1) placed around the metal pin thin plate (2), a caulking forming step of forming an outer caulking protrusion (m2) and an outer caulking measuring hole (m1) on the thin plate after or before the magnet installation hole forming step, a push-back step of pushing back a central opening area (h3) connected inside (h1a) of each magnet installation hole after blanking or half blanking it, an appearance blanking step of blanking the appearance (h4) of the metal pin thin plate (h4), and a laminating step of forming a laminating body (3) by performing caulking combination to the metal pin thin plate. [Reference numerals] (1) Pilot hole; (2) Magnet installation hole; (3) Internal caulking hole; (4) External caulking hole; (5) Central hole; (6) Half-blanking of a central opening area; (7) Blanking of an external diameter; (8) Lamination; (AA) Internal caulking protrusion; (BB) External caulking protrusion; (CC) Push back
