Embodiment 1

[0051] A claw pole for hybrid excitation generator, refer to figure 1 , comprising a bottom plate 11, a claw ruler 12 and a yoke 13 which are integrally arranged, and a magnet installation groove 121 is provided on both side walls of the claw ruler 12, and one end of the magnet installation groove 121 extends to the joint between the claw ruler 12 and the bottom plate 11, and the other end Through the claw ruler 12, the claw ruler 12 gradually narrows away from the base, and the bottom plate 11 is provided with a sliding groove 111 communicating with the magnet installation groove 121 for the magnet to slide in.

[0052] When in use, after the claw pole of the present application is docked with the existing claw pole, the magnet is slid in from the sliding groove 111 of the claw pole of the present application, and the magnet is completed after the base of the other claw pole is offset. Mounting, followed by positioning of the magnets via a wax seal.

Embodiment 2

[0054] A claw pole hot forging and finishing manufacturing process for hybrid excitation generators, used to manufacture the claw poles described in Embodiment 1, refer to figure 2 , including the following specific steps:

[0055] S1, blanking, cutting the cylindrical long embryo into several sections of originals to be processed through the cutting machine, wherein the ratio of height to diameter of the originals after cutting is less than 2.

[0056] S2. Heating. The original part is heated through an intermediate frequency furnace to facilitate subsequent forging.

[0057] S3, forging, the heated original is forged by a press and processed into a finished product.

[0058] S3 specifically includes: S3.1, upsetting, extruding the heated original through the punching machine to reduce the height and increase the cross section, and remove the oxide skin on the surface at the same time; S3.2, rough forging, through 630T friction The press performs preliminary forging on the...

Abstract

The invention discloses a claw pole for a hybrid excitation generator and a hot forging finishing manufacturing process thereof and relates to the technical field of claw pole production. The problemin the prior art that operation is complicated because of assembly of magnets and claw poles is solved. . Key points of the technical scheme are as follows: the pole comprises a bottom plate, a clawruler and a magnet yoke which are integrally arranged, magnet mounting grooves are formed in the two side walls of the claw ruler, one ends of the magnet mounting grooves extend to the butt joint position of the claw ruler and the bottom plate, the other ends of the magnet mounting grooves penetrate out of the claw ruler, the claw ruler is gradually narrowed in the direction away from the base, and sliding grooves communicating with the magnet mounting grooves and used for allowing magnets to slide in are formed in the bottom plate. The claw pole can be butted firstly, and then the magnets aremounted, so that the overall assembly is facilitated.

Description

technical field [0001] The invention relates to the technical field of claw pole production, in particular to a claw pole for a hybrid excitation generator and a hot forging finishing manufacturing process thereof. Background technique [0002] The hybrid excitation generator is a high-power and lightweight generator. Compared with ordinary generators, the difference is that permanent magnets are embedded between the front and rear claw poles of the generator rotor, which greatly increases the magnetic permeability of the claw poles, thus greatly The increase of generator output power and efficiency. [0003] Refer to attached Figure 5 , the existing claw pole is composed of a base plate 11, a claw ruler 12 and a yoke 13, wherein the claw ruler 12 is evenly arranged on the edge of the bottom plate 11, and the two side walls of the claw ruler 12 are provided with magnet installation grooves 121, the bottom plate 11, The claw ruler 12 and the magnetic yoke 13 are of an integ...
