Features and applications of stamping
Stamping production is completed by molds and presses. Compared with other processing methods, it has the following characteristics in technical and economic aspects:
(1) The dimensional accuracy of the stamping parts comes from the mold and has the same characteristics, so the quality is stable and the interchangeability is good.
(2) Due to the use of mold processing, it is possible to obtain parts that are impossible or difficult to manufacture by other processing methods, and have thin walls, light weight, good rigidity, high surface quality, and complex shapes.
(3) Stamping generally does not need to heat the blank, nor does it cut a lot of metal like cutting, so it not only saves energy, but also saves metal
(4) For ordinary presses, dozens of pieces can be produced per minute, while high-speed presses can produce hundreds or thousands of pieces per minute. So it is a rate processing method.
Because the stamping process has the above-mentioned outstanding characteristics, it is widely used in various fields of the national economy. For example, aerospace, machinery, electronic information, transportation, weapons, household appliances, and light industry all have stamping processes. Not only is it widely used in the industry, but everyone directly contacts with stamping products every day. Stamping can manufacture small precision parts in watches and instruments, as well as large covering parts for automobiles and tractors. For stamping materials, ferrous metals, non-ferrous metals, and certain non-metallic materials can be used.
Disadvantages There are also some disadvantages in stamping, which are mainly manifested in the two pollutions of noise and vibration during stamping. These problems are not entirely caused by the stamping process and the mold itself, but are mainly caused by the backwardness of traditional stamping equipment. With the advancement of science and technology, these two kinds of pollution will be resolved.
Stamping processing is a metal processing technology method, which is based on the plastic deformation of the metal. Under normal temperature conditions, the mold and the stamping equipment are used to apply pressure to the sheet material to cause the plastic deformation or separation of the sheet material. Shape, size, and performance parts (stamping parts)
Stamping is a processing method that applies external force to plates, strips, pipes and profiles, etc. through a punching machine and die to cause plastic deformation or separation to obtain a workpiece of the desired shape and size. Stamping is generally divided into cold punching and heat There are two types of calcination, and hot calcination is generally used less. Generally speaking, metal stamping refers to cold punching. Cold punching refers to metal stamping performed at room temperature. Cold punching can be divided into two categories: forming process and separation Process.
1. The separation process is to separate the sheet material according to a certain contour line to obtain a stamped part with a certain shape, size and cut surface. Separation process points: blanking, punching, cutting, trimming, etc.
2. In the forming process, the blank is plastically deformed without breaking to obtain a stamped part of a certain shape and size. The forming process is divided into: drawing, flanging, shaping, turning holes, bending, etc.
