Description

Technical Field

[0002] The fixed part of the motor is called the stator, on which pairs of static main magnetic poles with DC excitation are installed. The stator and rotor are important components of the motor. During the production process of the stator and rotor, it is often necessary to cut and punch the corresponding substrates. Generally, cutting is to provide better convenience for punching. Therefore, it is necessary to propose a shearing machine for stator and rotor punching processing.

In the utility model, the punching and shearing plate is attached to the surface of the base under the action of the limiting pressure roller, and cooperates with three punches to perform synchronous punching and shearing. Each group of stators and rotors is punched and sheared three times, and the plate body is pressed horizontally during the punching and shearing process, which can increase the quality rate of finished products. Three collection cavities are correspondingly arranged inside the base, which can classify and collect the waste materials left over from one punching, rotor punching sheets and stator punching sheets.

[0004] Although the existing shearing machine for processing stator and rotor punching sheets can solve the problem that the two-step design of shearing during punching sheet production wastes the overall production time, and corresponding collection operations need to be performed after punching and shearing, and the waste materials cannot be easily collected, but during the stator and rotor shearing process, manual guidance of the stator and rotor sheet is required.

It is not only inefficient but also prone to errors.

[0005] Therefore, in view of the above problems, a shearing machine for processing stator and rotor punching sheets is proposed. Utility Model Content
