Description

Technical Field

[0001] The utility model belongs to the technical field of motor equipment, in particular to a cutting device and motor processing equipment. Background Art

[0002] Traditional motors usually use round wires, while the emerging flat wire motors use flat rectangular wires. Using flat wires can significantly increase the fill rate of the coils in the slots because flat wires can be arranged closely without gaps between round wires. The higher the fill rate, the more wires there are in the coil, and the stronger the magnetic field generated, which increases the power of the motor. Flat wire motors are more in line with the needs of new energy vehicles for miniaturized, integrated and high-power density drive systems. Compared with traditional drive systems that are bulky, heavy and underpowered, flat wire motors are more competitive in the new energy vehicle market.

[0003] During the production process of the flat wire winding, the ends of the flat wires in the flat wire winding need to be cut so that the lengths of the ends of the flat wires on the flat wire winding remain consistent while retaining the ends of the flat wires at specific positions.

[0004] However, after the flat wire end is cut off, it needs to be discharged immediately, otherwise it will affect the subsequent cutting of other flat wire ends. The current cutting process is to cut it first, and then move the flat wire winding to another position to discharge the cut flat wire end, which will lead to low processing efficiency.
