Introduction to the fabrication methods and categories of automotive precision metal stamping parts

Precision metal automobile stamping parts fabrication: stamping with thin, uniform, light and strong characteristics can produce stamping parts with ribs, ribs, undulations or flanging that are difficult to make by other methods, so as to improve its rigidity. Due to the selection of fine molds, the workpiece accuracy can reach 0.01mm level, and the repeatability is high and the standard is the same, which can punch out holes, bosses, etc.

The stamping of precision metal stamping parts is mainly classified according to the process, which can be divided into two categories: separation process and forming process. The separation process can also be called blanking, and its purpose is to separate the fine stamping parts from the sheet along a certain contour line, while ensuring the quality requirements of the separated section.

Stamping of fine metal stamping parts is an efficient production method. The multi-station progressive die is selected, and multiple stamping processes can be completed on one press, realizing fully automatic from strip uncoiling, leveling, punching to forming and finishing. Production. The production efficiency is high, the labor conditions are good, and the production cost is low. Generally, thousands of pieces can be produced per minute. The purpose of the forming process is to plastically deform the sheet without breaking the blank to make a workpiece of the desired shape and size.

In practical production, multiple processes are often summed up and applied to a workpiece. Blanking, bending, shearing, deep drawing, bulging, spinning, and straightening are several primary stamping processes.
