Automobile stamping parts, as the name implies, are metal stamping parts that constitute automobile parts. In automobile stamping parts, one part becomes automobile parts directly after stamping, and the other part can become automobile parts only after welding, machining or painting. 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 cylinder, lifting lug and bracket. The design principle of all kinds of stamping parts is also different because of different application scope. The following briefly introduces the problems that should be paid attention to in the design of automobile stamping parts:

(1) Stamping parts must meet the product use and technical performance, and be easy to assemble and maintain.

(2) Stamping parts must be conducive to improving the utilization rate of metal materials, minimizing the varieties and specifications of materials and reducing the consumption of materials. Under the condition that the quality is completely up to standard, use low-priced materials and punch parts as little as possible without waste.

(3) Stamping parts must be simple in shape and reasonable in structure to simplify the die structure.

(4) The forming process of stamping parts is simple, which reduces the use of other processing methods and is beneficial to stamping operation, organization and realization of mechanized and automated production, thus improving labor productivity.

(5) Under the condition that stamping parts can be used normally, the requirements of dimensional accuracy grade and surface roughness grade should be as low as possible, which is beneficial to product interchange, reducing waste products and ensuring stable product quality.

(6) Stamping parts should be processed by using existing equipment, process equipment and process flow as much as possible, which is conducive to prolonging the service life of stamping dies.

These are some problems that should be paid attention to in the design of automobile stamping parts. Good design can greatly reduce the production cost while ensuring the quality of the workpiece.
