What principles should the processing technology of automobile stamping parts follow?

For automobile stamping parts, try to choose the appropriate size of the fixed-length board. After cutting from the steel plant, the automobile stamping parts do not need to be cut twice, which reduces the cutting cost; for coils, try to choose coil specifications and uncoiling forming processes to reduce the workload of secondary shearing and improve work efficiency.

The thickness of automobile stamping parts has deviation requirements. Usually within the allowable deviation range, first select the deviation plate.

Determining the shape and size of the unfolded sheet metal parts of the metal automobile stamping parts is the prerequisite for analyzing the degree of deformation of the stamping parts, design craftsmanship and drafting process regulations. If the shape of the metal plate is appropriate, not only can the uneven distribution of deformation along the metal plate be significantly improved, but also the forming limit can be increased, and the height of the lug and the margin of trimming can be reduced. In addition, for some parts that are directly formed after punching, if the accurate sheet shape and size can be given, the number of mold tests and adjustments can be reduced, thereby shortening the production cycle and improving productivity.

When designing and selecting materials for automotive stamping products, avoid the over-performance of products caused by high-quality materials. At the same time, on the premise of meeting product and process requirements, try to choose the materials and material thicknesses used in the existing mass-produced models to form a material platform to facilitate subsequent procurement and inventory management.
