Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a self-stacked riveting high-speed stamping die for stator and rotor cores. Background Art

[0002] The stator and rotor core is the core component inside the motor. It is used to increase the magnetic flux of the inductor coil to achieve the maximum conversion of electromagnetic power. When making the stator and rotor core, a stamping die is needed. The material is stamped continuously at high speed through the stamping machine and the stamping die. Multiple material sheets are stacked together and fixed together by riveting to form the stator and rotor core.

[0003] After the existing stator and rotor cores are stamped, a lot of iron filings will be generated in the die groove. If they are not cleaned in time, when the stator and rotor cores are stamped next time, they are easy to rub against the materials and cause wear, which will reduce the production quality of the stator and rotor cores.
