Abstract
PURPOSE:To linearly form the leg and yoke sections of a wound core by a method wherein magnetic steel plates are wound on a rectangular mold having level difference sections recessed to the inside at the middle sections of sides and the steel plates are recessed to the level difference sections by applying pressure from all external directions by molded substances. CONSTITUTION:An iron core wound magnetic steel plate 3 in multilayer is placed at the center of a press and is pressed from all directions through molded substances 8, 9. The molded substances 8, 9 are pressed in the level difference sections 6, 7 of a mold 4. In a wound core 1, recessed sections corresponding to the depth H, I of the level difference sections 6, 7 are formed by interposing the level difference sections 6, 7 between angles 3 for plastic deformation. Therefore, flat sections just return to a linear position by removing the heating of the molded substances 8, 9. With the depth H, I of the level difference sections 6, 7 of the mold 4 selected to the return amount of the recessed sections, leg and yoke sections become linear to facilitate the insertion of a coil and an insulator at the internal circumference will also not be damaged.
