Description

technical field [0001] The invention belongs to the processing technology of the cup-shaped rotor of the magnetic powder clutch, and relates to the improvement of the processing method of the cup-shaped rotor of the magnetic powder clutch. Background technique [0002] For the shape structure of a magnetic powder clutch cup rotor, see figure 1 . It consists of a disc-shaped cup bottom 1 and cup fins 2. The root of the cup fin 2 is vertically connected to the peripheral edge of the cup bottom 1 as a whole, and the cup fins 2 are evenly distributed along the circumference of the cup bottom 1 to form a cup rim. There is a gap 2a between two adjacent cup fins 2, and a hole 1a is formed on the disc surface of the cup bottom 1. At present, the processing method of the magnetic powder clutch cup rotor is: [0003] 1. Rough machining: Use electrical steel DT4E bar stock to carry out rough machining of the cup rotor according to the drawing requirements of the cup rotor to form th...
