| description | PURPOSE:To manufacture a rotor core having sufficient accuracy with a low cost by hot forging a material to form the general shape, gradually cooling it, then cutting and cold forging it. CONSTITUTION:A material 8 is hot forged to form the general shape of a rotor core which is formed in the prescribed sizes and shapes of a boss portion 2a, a coupling plate 3a and a pawl 4a. Then, the forging bur 9 of the general shape is removed, the core is gradually cooled, and the inner and outer diameters and coupling plate portion 3a are regularly pressurized by cold forging. Further, to form the general shape to the prescribed volume, the roughly finished state is cut. Eventually, the cut roughly finished shape is correctly adjusted by cold forging to precisely form the rotor core of the prescribed size and shape. |
