What are the characteristics of each of the six processes of stamping processing?

In the field of metal processing, stamping is a common technique that covers different processes such as piercing, punching, stretching, forging, piercing and embossing. Each of these processes has its own characteristics, and the following is a detailed explanation of the characteristics of these six processes.

First, the perforation process of stamping processing. Piercing by stamping is the process of punching out holes in metal materials by means of presses and molds. This process is characterized by high accuracy and the ability to make a large number of holes in a short period of time. Moreover, the shape and size of the perforations can be controlled by changing different molds, making it very flexible. However, this process has certain requirements for the thickness of the material, and too thick or too hard material may cause damage to the mold.

Secondly, the punching process of stamping, this is the process of punching and cutting sheet metal into the desired shape by means of a press. Its main feature is high efficiency and suitable for mass production. The punching process can punch out multiple parts at the same time, which greatly improves the production efficiency. However, the punching process requires high quality for the material, because the hardness, toughness and other characteristics of the material will affect the effect of punching and cutting.

Third, the stamping process of stretching process, it is through the press and mold will be flat sheet metal stretching into a certain depth of the hollow shape of the process. The characteristics of the stretching process are that it can improve the utilization rate of the material and reduce the generation of scrap. At the same time, as the material undergoes plastic deformation, it makes the shape and size of the product more stable. However, the stretching process is prone to wrinkling and rupture, and requires precise control of pressure and speed.

Fourth, the forging process of stamping processing, which is a method of utilizing impact or pressure to change the shape and properties of metals. Forging is characterized by its ability to improve the microstructure of the metal and enhance its mechanical properties. In addition, forging can produce parts with complex shapes. However, the forging process generates a large amount of heat and requires specialized equipment for cooling and processing.

Fifth, the piercing process of stamping processing is the process of piercing the metal material and forming a certain shape. This process is characterized by the fact that it can be carried out without destroying the surface of the material, and is therefore commonly used to manufacture some decorative products. However, because of the need to penetrate the material, the requirements for tools are higher, otherwise it may lead to product quality problems.

Sixth, the embossing process of stamping processing, which is the process of pressing patterns into the metal surface through pressure. This process is characterized by the ability to form a variety of patterns on the metal surface, increasing the beauty of the product. At the same time, the embossing process will not change the internal structure of the material, so it will not affect its mechanical properties. However, the embossing process requires high requirements for the design and manufacture of molds, which needs professional technical and equipment support.
