    A process for preparing a pole piece having spiders bent in the axial direction for the rotor of a generator in which a slug is obtained from a round metal bar, said slug is upset to a disc-shaped member, said member is formed with a plurality of radially and outwardly extending spiders on the outer periphery of and a boss on one surface of said member, said spiders are tapered on one surface and an annular bending recess is formed in said one surface of the spiders, said spiders are bent at said annular bending recess until the outer surface of the spiders lie on a plane right angles to the plane of said member to provide a semiprocessed product, and said semiprocessed product is in succession subjected to coining and sizing steps to thereby provide a complete pole piece having spiders bent in the axial direction.

    The invention of the invention relates to the t-technology for the manufacture of rotor pole poles, alternating-current transformers and can be used in the manufacture of electrical machines. A known method of manufacturing a pole of an alternator rotor, including a piece of a zipindric billet, its stamping and mechanical processing. The disadvantage of the known method is the high power of the pressing equipment used for the rotor pole shafts of a predetermined and complex configuration from a cylindrical billet. The purpose of the invention is to reduce the capacity of the pressing equipment. The goal is achieved by the method of manufacturing a rotor of an alternator, including a segment of a cylindrical billet, its stamping and machining; the claws of the stupas are bent at a right angle to the end of the central cylindrical boss. FIG. 1 shows a cylindrical billet; in fig. 2 - disc-shaped detail; in fig. 3 - detail with educated protrusions; in fig. 4 - oo cut; in fig. 5 - forming claw-shaped protrusions; in fig. 6 - the same section; in fig. 7 - detail with molded claw-shaped protrusions; on f | 11. 8 - Id jo,) 1lzr (h; n figs, 9 - .111. After siSzhi kog-theob-razverkh ledge; fig. 10 - the same, section; fig, 11 - detail of the calibration operation; fig- , 12 is the same section; Fig. 13 shows the pole of the generator rotor after: final processing; FIG. 14 is the same section; FIG. 15 is the same in perspective. The method of manufacturing the pole of the alternator is as follows: When performing the first operation, a cylindrical billet 1 of a given size (Fig. 1) is cut off from the rod. The disc-shaped part 2 (Fig. 2). Then the disc-shaped part is processed and molded on the base 3 of a cylindrical bobka 4 and protrusions 5. the part shown in Figures 7 and 8 is obtained. In the sixth operation, the clawed protrusions are bent at a right angle to the end of the central cylindrical bob (Figs 9 and 10), after which the calibration operation is carried out (Fig. 11 and 12). After that, the part is subjected to final processing to obtain the specified dimensions (Fig. 13 and 14). The invention makes it possible to reduce the power of the press equipment in the manufacture of the rotors of the alternators.
