The metal cold stamping process is generally used to process metal sheets into shallow concave shapes or curved profiles. It has the characteristics of fast processing speed and high accuracy. Can be used to produce a variety of everyday products, from car bodies to metal pallets. Metal stamping is a metal processing method. It is based on the plastic deformation of metal. It uses molds and stamping equipment to exert pressure on the sheet metal to cause plastic deformation or separation of the sheet material, thereby obtaining a certain shape, size and performance. Parts (stamping parts). The stamping forming process occupies an important position in the automobile body manufacturing process.
Metal stamping can be used to process shallow concave metal shapes. The processing requirements for molds are relatively high, and this process is only suitable for mass production. This process has high precision during processing and there is no obvious change in material thickness. When the ratio between depth and diameter becomes smaller, the machining process is very similar to deep drawing. Neither machining process significantly reduces the thickness of the material.
High-volume production of parts requires a combination of forming and cutting processes based on progressive tools. A series of molds is essential in rapid processing. During the machining of a part, it is sometimes necessary to perform a second operation on a previously formed part. Some parts may require 5 or more operations, reflecting the number of operations. This process can process sheet metal into cylindrical, conical and hemispherical shapes. The process is frequently combined with stamping and pressing, giving the entire design a wide range of options. For example, the characteristics of this process are significant when processing flange edges, asymmetric hubs and shapes with perforations.
