Auto stamping parts, as the name suggests, are metal stamping parts that constitute auto parts. In automobile stamping parts, some of them become auto parts directly after stamping, and the other part needs to be processed by welding, machining, or painting before they can become auto parts after stamping. There are many kinds of automobile stamping parts, such as spring tray, spring seat, spring bracket, end cover, cover, compression valve cover, compression valve sleeve, oil seal seat, bottom cover, dust cover, impeller, oil seal, etc. Tubes, lugs, brackets, etc. are all automotive stamping parts.
A large number of cold stamping processes are used in the production of automobile stamping parts, which is suitable for the needs of multi-variety and mass production of automobile stamping parts. In medium and heavy-duty vehicles, most of the cover parts such as body outer panels, and some load-bearing and support parts such as frame, carriage and other auto parts are auto stamping parts. The steel used for cold stamping is mainly steel plates and steel strips, which account for 72.6% of the steel consumption of the whole vehicle. The relationship between cold stamping materials and the production of automobile stamping parts is very close. The quality of the materials not only determines the performance of the product, but also directly affects the production. The process design of the automobile stamping process affects the quality, cost, service life and production organization of the product, so the rational selection of materials is an important and complex task.
Design principles of metal stamping 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 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 few and simple stamping processes, reduce the need for other methods to process, and be conducive to stamping operations, It is convenient for organizations to realize 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.
