Details of the difference between ordinary punching precision punching

What is punching? What is precision punching and ordinary stamping: Punching is the use of conventional or special punching equipment, power, so that the sheet directly in the mold by the deformation force and deformation, resulting in a certain shape, size and performance of the production of parts technology. Sheet metal, mold and equipment are three elements of stamping. Stamping is a cold deformation of metal processing methods. Therefore, it is called cold stamping or sheet metal stamping, referred to as stamping. It is a metal plastic processing (or pressure processing) one of the main methods, but also under the material forming engineering technology. Stamping used by the stamping die known as mold, referred to as die. Die is the material (metal or non-metallic) batch processing into the required pieces of special tools. Die in the stamping is essential, there is no dies to meet the requirements of bulk stamping production is difficult to carry out; no advanced die, advanced stamping process can not be achieved.

Punching process and mold, stamping equipment and stamping materials constitute the three elements of stamping, only they can be drawn with each other stamping parts. Compared with other methods of machining and plastic processing, stamping has many unique advantages in terms of technology as well as economy. Mainly as follows. (1) stamping processing of high production efficiency, and easy to operate, easy to achieve mechanization and automation. This is because the stamping is to rely on stamping die and stamping equipment to complete the processing, general presses the number of strokes per minute up to dozens of times, high-speed pressure to hundreds of times per minute or even more than a thousand times, and each stamping stroke on May get a punch. (2) stamping due to the mold to ensure the stamping parts of the size and shape accuracy Angle Drilling machine, and generally do not damage the surface quality of stamping parts, and die life is generally longer, so stamping quality and interchangeability is good, with ‘exactly the same’ Characteristics. (3) stamping can be processed out of the larger size range Steel Punching, the shape of the more complex parts, such as a small stopwatch to the clock, large automotive stringers, panels, etc., plus stamping material cold deformation hardening effect, stamping strength and Stiffness are higher. (4) stamping generally no chips and scrap material generated, less material consumption, and no other heating equipment, which is a province of material, energy-saving processing methods, stamping parts of the lower cost. As the stamping has such advantages, stamping processing in a wide range of national economy in a wide range of applications. For example, in the aerospace, aviation, military, machinery, agricultural machinery, electronics, information, railway, telecommunications, transportation, chemical, medical equipment, household appliances and light industry and other departments have stamping processing.

Not only the entire industry have used it, and each person directly with the stamping products in contact. Like aircraft, trains, cars, tractors there are many large, medium and small stamping parts. Car body, frame and rims and other parts are stamping out. According to the survey statistics, bicycles, sewing machines, watches, 80% of stamping parts; TV, tape recorders, camcorders, there are 90% of stamping parts; there are food metal shell, steel boilers, pots and enamel bowl stainless steel tableware Structural Steel Fabrication Equipment, All using the stamping die processing products; even the computer hardware is also the lack of stamping parts. However, the stamping die used in general have a special nature, and sometimes a number of complex parts need to die processing to shape, and the mold manufacturing high precision, high technical requirements, is a technology-intensive products. Therefore, only in the stamping parts production of large quantities of the case, the advantages of stamping can be fully reflected in order to obtain better economic benefits. Precision punch with what characteristics In some metal sheet metal processing, precision punch has a wide range of applications, such as computers, home appliances, vehicles and some other products processing, in the next content will introduce the main features of precision punching what. The first point, since it has become a precision punch, then the high-precision certainly is not missing features, and precision punch frame is usually used steel, with high rigidity, is a high rigidity, high precision equipment . Second, the precision punch press transmission center can be consistent with the overall center of the machine, so the precision punch to the center of gravity can be more balanced, thus ensuring the accuracy and stability of stamping. Third, the precision punch is an environmentally friendly energy-saving machines, not only the appearance is relatively beautiful, but also can effectively reduce the noise issued, energy consumption is relatively small. The above is some of the main features of precision punching machine, can be seen from the above content, precision punch design concept is more advanced, not only has better machine performance, and reflects the environmental protection, energy conservation awareness, is in line with modern society Concept of machinery and equipment.

Of course, stamping there are some problems and shortcomings. Mainly in the stamping process noise and vibration generated two kinds of pollution, and the operator’s safety accidents occur. However, these problems are not entirely due to the stamping process and the mold itself brought, but mainly due to the traditional stamping equipment and backward manual operation caused. With the progress of science and technology, especially the development of computer technology, with the progress of electromechanical integration technology, these problems will be solved as soon as possible two perfect. Precision stamping generally can be called a molding, to minimize stamping after processing. Ordinary stamping is stamping, still need post-processing.
