What are the technical characteristics of high-speed precision stamping parts?

High-speed precision stamping parts are mass-produced with high-speed precision press production lines and multi-station carbide progressive dies as the main process means, which also include progressive composite processes such as blanking, deep drawing, bending, flanging, and riveting. mold. Most of the materials are coiled strips, which are automatically discharged by the automatic feeding rack, and generally need to be leveled by a leveling machine. The leveled material is automatically fed by the feeder attached to the high-speed press. In order to improve the stamping performance, the surface of the material needs to be dipped or sprayed with stamping oil. When selecting stamping oil, it is necessary to evaluate the needs of subsequent processes. The parts are generally automatically packaged by the reel of the feeder, and the parts are added with interlayer paper or plastic film, or are directly fed into the collector by the conveyor belt. Some automotive stamping parts require post-fabrication, such as cleaning, electroplating, etc. Most of the high-speed precision stamping parts are produced automatically by a single machine, and individual complex parts are produced by a multi-machine automatic production line.
The stator and rotor core of high-speed precision stamping parts are important components 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 use a general die to punch out stator and rotor punching pieces (loose pieces), and then use rivet riveting, buckle, argon solitary welding and other methods to make the iron core. For the rotor core of the AC motor, the inclined groove needs to be twisted manually. The stepper motor requires uniform magnetic properties and thickness directions of the stator and rotor cores, and a certain angle of rotation is required between the stator core and the rotor core.With the continuous development of industrial production technology, in the technical fields of motors, electrical appliances, etc., high-speed stamping multi-station progressive dies have been widely used to manufacture automatic laminated cores, such as stator and rotor cores of various micro motors, and mountain-shaped cores. , U-shaped, small transformer core, etc. Among them, the stator and rotor cores can also be provided with torsional stacking inclined grooves, and a large-angle rotary stacking riveting structure between the punching pieces. Compared with ordinary stamping dies, multi-station progressive dies have the advantages of high stamping accuracy, high production efficiency, long service life, good dimensional accuracy consistency of stamped iron cores, easy automation, and suitable for mass production. The direction of mold development. There are many types of electronic stamping parts, and the structure is also complex. The general precision requirements of electronic stamping parts are relatively high. At the same time, the thickness of the stamping material is required to be accurate and uniform, the surface is smooth, no spots, no scars, no scratches, no surface cracks, etc. The yield strength of the material is uniform, no obvious directionality, High uniform elongation and low work hardening. Heat exchanger fins refer to the metal sheets for heat transfer in the heat exchange device, which can increase the heat exchange surface area of ​​the heat exchange device and improve the heat exchange efficiency. The annual output of heat exchanger fins reaches hundreds of millions, and the material is usually 0.08~0.20mm thick aluminum foil, so it must be produced by high-speed progressive die. The semiconductor lead frame is the carrier of the semiconductor chip and acts as the interface between the semiconductor device and the printed circuit board (PCB). Its remarkable features are: surface quality, shape accuracy, shape and position accuracy, accumulated error, appearance characteristics and other requirements, which are the highest among all stamping parts. In particular, the shape of the inner lead is basically like a thin and long cantilever in the shape of a crab’s foot, which is different from the conventional stamping process.
