Abstract

PURPOSE:To improve the material yield and to reduce the cost of dies by disposing the chordal direction of a sector iron core plate along the longitudinal direction of a hoop material and arranging the plates symmetrical so that the part of the outer periphery makes contact with the widthwise direction of the material. CONSTITUTION:The chordal direction of a sector iron core plate 17 is disposed along the longitudinal direction of a hoop material 1, arranged symmetrical so that the part 21 of the outer periphery makes contact with the widthwise direction of the material 1, and the parts 20-22 of the profile are simultaneously cut and punched at the plate 17. For example, holes 11, 12 of heart shape are formed at the prescribed interval at the material 1, the isolating part 15 betweek the ends 11a, 12a of the holes 11, 12, respectively is cut, and cut at the notch 14 between the heads 11b and 12b of the holes 11, 12, respectively, thereby forming outer peripheries 21, 22. Simultaneously, the holes 11, 12 are isolated via the core bolt holes 18, 18 and 19, 19.
