What are the technical characteristics of high-speed precision stamping parts? High-speed precision stamping parts have a wide variety, large production volume, high precision, complex shapes, thin plate materials and diverse materials. The main types of high-speed precision stamping parts have the following technical characteristics. The stator and rotor cores are important parts of the motor, and its quality directly affects the technical performance of the motor. The traditional motor stator and rotor core manufacturing process is to stamp out stator and rotor punching pieces (scattered pieces) with a general punching die, and then use rivets, clasps, argon welding and other methods to make the core. The rotor core of the AC motor needs to be twisted out of the chute manually. Stepping motors require uniform magnetic properties and thickness directions of the stator and rotor cores. The stator core and rotor core punching pieces are required to rotate at a certain angle. For example, they are produced by traditional methods, which are inefficient and difficult to meet the technical requirements. With the continuous development of industrial production technology, in the technical fields of motors and electrical appliances, multi-station progressive dies for high-speed precision stamping parts have been widely used to manufacture automatic laminated structural cores, such as stator and rotor cores of various micromotors, and Mountain shape, U shape, small transformer core, etc. Among them, the stator and rotor cores can also be provided with torsion stacking chute, with large-angle rotating stacking riveting structure between the punching pieces. Compared with ordinary punching dies, multi-station progressive die has the advantages of high stamping accuracy, high production efficiency, long service life, good consistency in the dimensional accuracy of the stamped iron core, easy automation, and suitable for mass production. It is the precision of the micro-motor industry. The direction of mold development.
