Description

Technical Field

[0001] The utility model belongs to the technical field of stator core processing, in particular to a processing device for the inclined slots of the stator core of a motor. Background Art

[0002] The stator core is an important component of the motor's magnetic circuit. Together with the rotor core and the air gap between the stator and rotor, it forms the complete magnetic circuit of the motor.

[0003] During the production of the stator core, stamping equipment is required to stamp out the bevel grooves on the stator core. After the stamping is completed, the existing stamping equipment usually requires workers to take out the stator core and waste in the mold. Since the waste after stamping will remain in the mold, it is very inconvenient for the workers to take it out, and it will take a lot of time, reducing the production efficiency of the stator core. Therefore, we proposed a processing equipment for the bevel grooves of the motor stator core. Utility Model Content
