Stamping Parts 10
Application of stamping parts
1. Electrical parts stamping plant. This kind of factory is a new industry, which develops with the development of electrical appliances. These factories are mainly concentrated in the south.
2. Automobile and other industries parts stamping. It is mainly formed by punching and shearing. Many of these enterprises belong to standard parts factories and some independent stamping plants. At present, there are many small factories around some automobile factories or tractor factories.
3. Stamping in the automotive industry. Drawing is the main method. In China, this part is mainly concentrated in automobile factories, tractor factories, aircraft manufacturers and other large factories, and independent large-scale stamping and drawing plants are rare.
4. Daily necessities stamping factory. Some handicrafts, tableware and so on, these factories also have the big development in recent years.
5. Special stamping enterprises. For example, the stamping of aviation parts belongs to this kind of enterprise, but these process factories are also included in some large factories.
6. Stamping plant for household electrical parts. These factories appeared only after the development of household appliances in China, and most of them are distributed in household appliance enterprises.
Technological requirements of metal stamping parts
1. The materials used for metal stamping parts should not only meet the technical requirements of product design, but also meet the requirements of stamping process and processing requirements after stamping (such as cutting, electroplating, welding, etc.). A kind of
2. When designing the structural shape of metal stamping parts, simple and reasonable surfaces (such as plane, cylindrical surface, spiral surface) and their combination should be adopted. At the same time, the number of machined surfaces and the processing area should be small as far as possible. A kind of
3. Selecting the reasonable method of blank preparation in mechanical manufacturing can directly use profile, casting, forging, stamping and welding, etc. The selection of blank is related to the specific production technical conditions, and generally depends on the production batch, material properties and processing possibility. 4. Requirements of metal stamping formability. For forming process, in order to improve stamping deformation and product quality, the material should have good plasticity, small yield strength ratio, large plate thickness directivity coefficient, small plate plane directivity coefficient, and small yield strength to elastic modulus ratio. For the separation process, it is not necessary for the material to have good plasticity, but it should have a certain plasticity. The better the plasticity is, the more difficult it is to separate. A kind of
5. Specify the processing cost of parts with appropriate manufacturing accuracy and surface roughness. The processing cost of metal stamping parts will increase with the improvement of precision, especially in the case of high precision, this increase is significant. Therefore, when there is no basis, high precision should not be pursued. A kind of
In the same way, the surface roughness of metal stamping parts should also be regulated according to the actual needs of the matching surface. The processing technology of metal stamping parts is more complex. In order to ensure the performance of metal stamping parts can meet the use requirements, it is necessary to follow the corresponding process requirements to ensure the production feasibility.
