Description

Technical Field

[0001] The invention relates to a forging, in particular to a permanent magnet generator rotor punching forging. Background Art

[0002] Permanent magnet generator refers to a power generation device that converts mechanical energy converted from heat energy into electrical energy. The permanent magnet generator eliminates the excitation winding, carbon brush, and slip ring structure of the excitation generator. The whole machine structure is simple, avoiding the excitation winding of the excitation generator that is easy to burn out, break, and the carbon brush and slip ring are easy to wear. It has high reliability. Forgings refer to workpieces or blanks obtained by forging and deforming metal billets. By applying pressure to the metal billet to cause it to deform plastically, its mechanical properties can be changed. Forgings can be divided into cold forging, warm forging, and hot forging according to the temperature of the billet during processing. Cold forging is generally processed at room temperature, and hot forging is processed at a temperature higher than the recrystallization temperature of the metal billet. Forging can eliminate the looseness and holes of the metal, so that the mechanical properties of the forging can be improved.

[0003] The permanent magnet generator is equipped with a rotor and a rotor punching forging. When the punching forging is in use, a large amount of copper wire is wrapped around the surface. Long-term working rotation easily generates a lot of heat. Although the generator casing surface is provided with heat dissipation holes, the heat in the middle of the rotor is difficult to transfer to the rotor surface, and it is not conducive to dissipating from the heat dissipation holes, which leads to the phenomenon of excessive rotor temperature and damage, shortening the service life. To this end, we propose a permanent magnet generator rotor punching forging. Summary of the invention
