As we all know, there are hundreds of kinds of parts, large and small, on cars, and metal stamping parts of auto parts account for a large part. Metal stamping of auto parts is a production technology of product parts with the help of the power of conventional or special stamping equipment to make the sheet directly subject to the deformation force and deform in the die, so as to obtain a certain shape, size and performance. In order to obtain good stamping products, we must do a good job in the design before stamping.

1. Under the condition of ensuring normal use, 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 ensure the stability of product quality.

2. Meet the use and technical performance of the product, and be easy to assemble and repair.

3. The shape is simple and the structure is reasonable, which is conducive to simplifying the die structure and the number of processes, that is, using less and simple stamping processes to complete the processing of the whole parts, reducing the processing by other methods, and is conducive to stamping operation, which is convenient for organizing and realizing mechanized and automatic production, so as to improve labor productivity.

4. The design of metal automobile stamping parts should be conducive to the use of existing equipment, process equipment and process flow to process them as much as possible, and be conducive to the extension of the service life of the die.

5. It is beneficial to improve the utilization rate of metal materials, reduce the variety and specification of materials, and reduce the consumption of materials as much as possible. If allowed, low-cost materials shall be used to make the parts blanking without waste and less waste as far as possible.

Processing of stamping parts of auto parts stamping processing of auto parts is a metal cold deformation processing method. It is one of the main methods of metal plastic processing (or pressure processing). It also belongs to material forming engineering technology. Before design, we should pay more attention to obtain good results.
