Design principles of metal stamping parts for stainless steel automotive sheet metal parts
- (1) The designed metal stamping parts must meet the product use and technical performance, and be easy to assemble and repair.
- (2) The designed stamping parts must be conducive to improving the utilization rate of metal materials, reducing the variety and specifications of materials, and reducing material consumption as much as possible. Use low-cost materials where possible, and make parts as scrap-free and blank as possible.
- (3) The designed automobile stamping parts must be simple in shape and reasonable in structure, so as to facilitate the simplification of the mold structure and the number of processes, that is, to complete the fabrication of the entire part with fewer and simple stamping processes, reduce the need for other methods to process, and be conducive to stamping operations. , to facilitate the organization of mechanized and automated production to improve labor productivity.
- ⑷ For the designed stamping parts, under the condition of normal use, try to make the dimensional accuracy grade and surface roughness grade lower, which is conducive to the exchange of products, reduces waste, and ensures stable product quality.
- ⑸ The designed stamping parts should be conducive to the use of existing equipment, process equipment and process flow as much as possible to process them, and is conducive to prolonging the service life of the stamping die.
Application fields of stainless steel sheet metal parts and metal stamping parts
- (1) Stamping in the automotive industry. Mainly draw. In my country, this part is mainly concentrated in large factories such as automobile factories, tractor factories, and aircraft factories. There are few independent large-scale stamping and drawing factories.
- (2) Stamping of auto parts and components. Mainly punching and shearing. Many companies in this sector are classified as standard parts factories, and there are also some independent stamping factories. At present, there are many such small factories near some automobile factories or tractor factories.
- (3) Electric device stamping factory. This type of factory is a new industry, developed with the development of electrical appliances, and the factories in this sector are mainly concentrated in the south.
- (4) Stamping factory for daily necessities. Making some handicrafts, tableware, etc., these factories have also developed greatly in recent years.
- (5) Home appliance parts stamping factory. These factories only appeared after the development of household appliances in my country, and most of them are distributed in household appliance enterprises.
- (6) Special stamping enterprises. For example, the stamping of aviation parts belongs to this type of enterprises, but these process factories are also classified as some large factories.
