Abstract:
A stamping unit comprises a punch (A9), a die (D9), and a guide part (170). The guide part (170) has an upper member (171) that is placed so as to face a side edge part of the upper main surface of an electrical steel, and a lower member (172) that includes a facing surface (Fu2), which faces the lower main surface of the electrical steel. The lower member (172) includes an overlapping part (OV1) that overlaps with the upper member (171) when viewed from the vertical direction, and a non-overlapping part (OV2) that does not overlap with the upper member (171) when viewed from the vertical direction and projects further on the central part side in the width direction of the electrical steel, relative to the upper member (171). At least some of the facing surface (Fu2) in the non-overlapping part (OV2) is positioned higher than the facing surface (Fu2) in the overlapping part (OV1).
