参数
Rockwell hardness tester is used for hardness testing of metal stamping parts. Small stamping parts with complex shapes can be used to test. The plane is very small and cannot be tested on ordinary bench Rockwell hardness tester
stamping processing includes blanking, bending, deep drawing, forming, finishing and other processes. The materials processed by stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal strip materials, such as carbon steel plate, alloy steel plate, spring steel plate, galvanized plate, tinplate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate, etc
design principle
⑴ the designed stamping parts meet the product use and technical performance, and can be easily assembled and repaired
⑵ the designed stamping parts are conducive to improving the utilization rate of metal materials, reducing the variety and specification of materials and reducing the consumption of materials as much as possible. Materials with appropriate price shall be used when allowed, so as to make the parts blanking without waste and less waste as far as possible
⑶ the designed stamping parts have simple shape and reasonable structure, so as to simplify the die structure and simplify the number of processes, that is, complete the processing of the whole part with less and simple stamping processes, reduce the use of other methods, and facilitate the stamping operation, facilitate the organization and Realization of mechanized and automatic production, so as to improve labor productivity
⑷ when the designed stamping parts can be used normally, the requirements for dimensional accuracy grade and surface roughness grade shall be lower as far as possible, which is conducive to the exchange of products, reduce waste products and protect the stability of product quality
⑤ the designed stamping parts shall be conducive to processing them with existing equipment, process equipment and process flow as far as possible, and to prolong the service life of the stamping die
Hardware stamping parts application industry
1) stamping in automobile industry. Mainly deep drawing. In China, this part is mainly concentrated in large factories such as automobile factories, tractor factories and aircraft manufacturers, and independent large stamping and drawing plants are rare
(2) stamping of parts in automobile and other industries. Mainly punching and shearing forming. Many enterprises in this sector belong to standard parts factories and some independent stamping factories. At present, there are many such small factories near some automobile factories or tractor factories
(3) electrical parts stamping plant. This kind of factory is a new industry, which has developed with the development of electrical appliances. This department is mainly concentrated in the south
(4) daily necessities stamping factory. Make some handicrafts, tableware, etc. these factories have also made great development in recent years
(5) stamping plant for household electrical appliances. These factories emerged only after the development of electrical appliances in my home, and most of them are distributed in household appliance enterprises
(6) special stamping enterprises. For example, the stamping of aviation parts belongs to such enterprises, but these craft factories are also classified in some large factories
