Stamping structure of stator and rotor iron core sheet
By introducing deburring stations into the iron chip stamping structure of the motor stator, and using arc-shaped convex compression and bending burrs, the problem of burrings at the bottom edge of the groove-shaped holes during the punching of the iron chip of the motor stator is solved, and the flatness of the iron chip and the flatness of the stack are achieved.

AI Technical Summary
When the iron chip of the existing motor stator is punched with groove-shaped holes, burrs are easily generated at the bottom edge of the groove-shaped holes, resulting in uneven stacking, affecting the performance of the motor, and the iron chip is easily bending and deformed during the deburring process.
A stamping structure of a stator iron chip is designed, including a shaft hole forming station, a groove punching station, a deburring station and a through-sheet forming station. The deburring station removes burrs by providing arc-shaped protrusions, squeeze and bend burrs on the lower die base at the bottom of the iron chip to deform them along the edge of the arc.
The burrs on the bottom edge of the groove-shaped hole are effectively removed, and the flatness of the iron chip is achieved, the problem of uneven stacking is avoided, and the bending deformation of the iron chip is reduced.
