15 years of stamping experience tells you the main characteristics and working process of precision stamping parts

In the process of working, precision stamping parts mainly rely on presses and molds to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, so as to obtain workpieces of the required shape and size (precision stamping parts)的Forming processing method. Stamping and forging are both plastic processing (or pressure processing), collectively referred to as forging. The blanks to be stamped are mainly hot-rolled and cold-rolled steel plates and strips. Compared with castings and forgings, precision stamping parts have the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with stiffeners, ribs, undulations or flanges that are difficult to manufacture by other methods to improve their rigidity. Due to the use of precision molds, the precision of the workpiece can reach the micron level, and the repeatability is high, the specifications are consistent, and holes, bosses, etc. can be punched. Precision stamping parts are generally no longer processed by cutting, or only a small amount of cutting processing is required. The accuracy and surface condition of hot stamping parts are lower than cold stamping parts, but still better than castings and forgings, and the cutting amount is less. Precision stamping is an efficient production method. Using compound dies, especially multi-station progressive dies, multiple stamping processes can be completed on one press to realize the process from strip uncoiling, leveling, punching to forming and finishing. Fully automatic production. High production efficiency, good working conditions, low production cost, generally hundreds of pieces per minute can be produced. Precision stamping parts are mainly classified according to their process, and the process and the forming process can be separated during operation. The separation process is also called punching, and its purpose is to separate the stamping parts from the sheet along a certain contour line while ensuring the quality requirements of the separated section. The surface and internal properties of the sheet material used for stamping have a great influence on the quality of the stamped product. The stamping material is required to have a good thickness, uniformity, smooth surface, no spots, no scars, no scratches, no surface cracks, etc.; uniform yield strength, no obvious Directionality; high uniform elongation. Low yield ratio and low work hardening. The main features of precision stamping parts (1) Precision stamping parts are manufactured by stamping under the premise of low material consumption. The parts are light in weight and rigid. After the sheet material is plastically deformed, the internal structure of the metal is improved. Increase the strength of stamping parts.　　⑵ The precision stamping parts have high dimensional accuracy, the same size as the mold parts, and good interchangeability. No further machining is required to meet general assembly and use requirements.　　⑶ In the stamping process, because the surface of the material is not damaged, the precision stamping parts have a good surface quality and a smooth and beautiful appearance. This provides convenient conditions for surface painting, electroplating, phosphating and other surface treatments. The above is the content shared for everyone, I hope it will be helpful to everyone. Hardware, 15 years of craftsmanship, focusing on precision metal stamping parts, silk-like precision + 16 strict quality inspections, and the concept of the result of your needs as the result of the work, let you choose, choose to rest assured!
