Set rotor core ignition coil iron core which technology, for you to introduce the technology progress of iron core rotor core ignition coil relevant knowledge, please refer to, thank you for your reading.
In the motor industry, the fixed and rotor iron core is one of the important parts of the electric machine. Its quality directly affects the technical performance of the motor.
The iron core of the fixed and rotor core ignition coil can also be equipped with a torsional stack groove, a large angle rotary stack riveting structure between the punching sheets, etc., compared with the ordinary punching die. The multi-position input die has the advantages of high punch precision, high production efficiency, long service life, good accuracy of the size of the forged iron core, easy to achieve automation, and suitable for mass production. It is the direction of precision mold development in the motor industry. The fixed and rotor automatically stacked riveting die has a high manufacturing accuracy, advanced structure, a rotary mechanism with high technical requirements, a counting separation mechanism, and a safety mechanism. Iron core automatic double riveting, rotor twisted oblique double riveting, large angle rotary double riveting punching step is placed on the fixed, rotor stamping material work position. The main parts of the progressive die, convex die, concave die are made of cemented carbide materials, each grinding edge can be washed more than 1.5 million times, the total die life of more than 120 million times.

　The traditional method of making iron core ignition coil iron core is to use common common mold to punch out fixed, rotor punching pieces(pieces), through the piece, and then use rivet riveting, buttoning pieces or argon arc welding to make iron core. For the rotor core of the AC motor, it is also necessary to twist the tilt groove by hand. The step motor requirements are fixed, the magnetic performance and thickness direction of the rotor core are uniform, and the rotation of the stator core and the rotor core punch are required. Angle, such as making by traditional methods, Low efficiency, precision is difficult to meet technical requirements. Now with the rapid development of high-speed stamping technology, in the field of motors, electrical appliances and other fields, high-speed stamping multi-position stage molds have been widely used to manufacture automatic stack type structural core ignition coil core.
Everyone is different. Of course, there are different ideas. Since it is a matter of your work, if you read the above article, you will find it necessary to modify or supplement it. I hope you can point it out in time.
