Abstract
PURPOSE: To simplify the fabrication of iron core by cutting one part of the circumference of iron core formed in the ring shape to bring its length to the different plural plates and then by laminating them to the circular form to joint the meeting part so as to make a forming.
CONSTITUTION: A continuous iron core element sheet 1 is wound to the circular shape in the designated length and its one part is fixed by a fixing jig 2 and then the sheet is cut to the center direction in such a way that a rectangular shaped iron core element 1 having the designated number of the different dimension, is obtained. After that holding the designated number of the sheet, it is divided and one end of the cut part of the sheet is placed in the groove of a jig 3 and the other end is left in irregular form. Then, the element sheet 1 is assembled to a circular holding device 4 from its outer circumference using its flexibility so that a cutting both parts 1c is united eath other. Next, a fastening jig 5 composing of a fastening plate 5c jointing with a bolt 5b and a plate 5a corresponding to the length of the width of the rectangular iron core, holds the element sheet 1 and it is placed into a pressurizing device to form it in rectangular form by pressure. Then, annealing treatment is effected on it and all jigs are removed.
