PROBLEM TO BE SOLVED: To provide a core piece rotational stacking device which is unlikely to restrict the shape of a core piece.SOLUTION: A core piece rotational stacking device 1 comprises: a dice 14 that punches a steel sheet 2 by cooperating with a punch 13; and a rotary part 20 which is provided in the dice 14, stacks a core piece 3A punched from the steel sheet 2 and is rotated around a rotation axial line L extending in a direction of punching. The rotary part 20 includes a plurality of mold holes 22 and 23 for punching a contour of the core piece 3A by cooperating with the punch 13, and shapes of the paired mold holes 22 and 23 have a relation of point symmetry with the rotation axial line L as a center.SELECTED DRAWING: Figure 4 |
