The high-speed press for stator and rotor sheets uses the punch on the die to stamp the coil. The precision and quality of the motor stator and rotor are related to the basic function of the motor. There are many Precautions for stamping stator and rotor sheets. Every process must be rigorous, from reasonable material selection, correct design, setting of processing requirements, quality inspection, etc. Manufacturing must not only ensure quality, but also adopt efficient production methods.
Precautions for stamping stator and rotor sheets，
Aspects that need to be understood and designed in advance:
the shape of the stator and rotor sheets; the size and material hardness parameters; design of the stamping process flow。 (the raw materials of the motor stator and rotor sheets should have certain magnetic conductivity and heat resistance, etc., because the motor torque and load require stable performance materials; the precision design of the inner diameter, number of teeth, number of sections, tooth shape, etc. of the stator and rotor should take into account the actual situation, and accurate control of the precision components of these parameters can ensure the dynamic performance of the stator and rotor; the processing equipment should choose high-speed and high-precision equipment, such as samhoor stator and rotor punching high-speed press, production efficiency and quality must be guaranteed at the same time; the final data of the stamped product, such as the pitch, tooth pressure circle runout, etc., must meet the requirements.）
Technical knowledge that needs attention:
1. The surface of the motor stator and rotor punching should be thin and uniform;
2. The tooth groove distribution should be uniform, the slot division should be accurate, and the difference in tooth width should comply with the drawing requirements;
3. The stator and rotor punching sheets should be uniform in thickness, the surface should be flat, and the burrs produced by punching should be small;
4. The dimensional accuracy should comply with the drawing requirements, and the internal dimensions and matching dimensions of the core punching sheets should meet the accuracy requirements;
5. The mold design of the stator and rotor punching sheets, The position and size of punching and concave, material yield strength, and material thermal conductivity should be taken into consideration;
6. During stamping, the verticality of the punch and the rigidity of the pressure test should be sufficient, the gap between the punch and the concave should be reasonable, and the high precision of the guide rail can reduce the generation of burrs;
7. When stacking, the burr direction of the punching sheet needs to be consistent. If the punching sheet has broken sheets, broken teeth, or cracks, it must be removed in advance;
8. Consider the selection of composite molds for the stator and rotor stamping process, the productivity and material utilization rate are relatively high, and the blanking-punching composite stamping.
Through the actual stamping in the factory, practice can always summarize a lot of knowledge related to Motor stator and rotor punching technology. Motors can be seen everywhere in modern life, and there are many specifications of motors, and the dimensions of the punching sheets are different. Understand the Precautions for stamping stator and rotor sheets to ensure efficient and high-quality production.
