The advantages of metal stamping parts processing

The die used for stamping is called a stamping die, abbreviated as a die. A die is a special tool for batch processing of materials (metal or non-metal) into the required punching parts. Dies are very important in stamping. Without a die that meets the requirements, it is difficult to carry out mass stamping production; without an advanced die, advanced stamping technology cannot be achieved. Stamping process and dies, stamping equipment and stamping materials constitute the three elements of stamping processing, and stamping parts can be obtained only when they are combined with each other.
Compared with other methods of mechanical processing and plastic processing, metal stamping processing has many unique advantages in terms of technology and economy. The main performance is as follows.
The production efficiency of stamping parts processing is high, and the operation is convenient, and it is easy to realize mechanization and automation. This is because stamping relies on die and stamping equipment to complete the processing. The number of strokes of ordinary presses can reach dozens of times per minute, and the high-speed pressure can reach hundreds or even thousands of times per minute. May get a punch.
During stamping, because the die ensures the size and shape accuracy of the stamping parts, and generally does not destroy the surface quality of the stamping parts, and the life of the die is generally long, the stamping quality is stable, the interchangeability is good, and it has the characteristics of "exactly the same".
Stamping parts are processed into parts with a wide range of sizes and complex shapes, such as stopwatches as small as clocks, as large as automobile longitudinal beams, covering parts, etc., plus the cold deformation hardening effect of the material during stamping, the strength and stiffness of stamping are higher. high.
Stamping generally does not generate chips and scraps, consumes less material, and does not require other heating equipment, so it is a material-saving and energy-saving processing method, and the cost of stamping parts is low. Metal stamping parts process parts with a wide range of sizes and complex shapes, such as stopwatches as small as clocks, covers, etc., plus the cold deformation hardening effect of the material during stamping, the strength and stiffness of the stamping are high.
The processing of metal stamping parts is a production technology of product parts with a certain shape, size and performance by means of the power of conventional or special stamping equipment, so that the sheet metal is directly subjected to deformation force in the mold and deformed. Sheet material, mold and equipment are the three elements of stamping processing. Stamping is a metal cold deformation processing method. Therefore, it is called cold stamping or sheet stamping, or stamping for short. It is one of the main methods of metal plastic working (or press working), and also belongs to material forming engineering technology.
Because stamping has such advantages, stamping processing is widely used in various fields of the national economy. For example, there are stamping processes in aerospace, aviation, military industry, machinery, agricultural machinery, electronics, information, railways, post and telecommunications, transportation, chemicals, medical equipment, household appliances and light industry. Not only is it used by the entire industry, but everyone is directly connected to stamping products. There are many large, medium and small stamping parts on planes, trains, automobiles and tractors. car body, car
Parts such as frame and rim are processed by metal stamping parts. According to relevant survey statistics, 80% of bicycles, sewing machines, and watches are stamped parts; 90% of TV sets, tape recorders, and cameras are stamped parts; there are also food metal cans, steel boilers, enamel bowls and stainless steel tableware. All of them are stamped products using molds; even the hardware of computers cannot lack stamping parts. However, the molds used in stamping processing are generally specialized. Sometimes a complex part needs several sets of molds to be processed and formed, and the mold manufacturing has high precision and high technical requirements, which is a technology-intensive product. Therefore, only in the case of large production batches of stamping parts, the advantages of stamping processing can be fully reflected, so as to obtain better economic benefits.
Of course, stamping also has some problems and disadvantages. It is mainly manifested in the noise and vibration generated during the stamping process, and the operator's safety accident occurs from time to time. However, these problems are not entirely caused by the stamping process and the mold itself, but are mainly caused by traditional stamping equipment and backward manual operations.
