the structural shape and size of automobile body stamping parts determine that the process has a certain degree of complexity, and it is impossible to directly process them in one process. at least three processing processes are required. however, the spatial surface shape of the stamping parts of the automobile body and the bosses, ribs and ridges on the curved surface should be formed by one-time deep drawing as much as possible, otherwise it is difficult to ensure the smooth surface and the consistency of the geometric shape of the stamping parts of the automobile body.
automobile stamping parts technology is developing in the direction of precision, multi-function, high efficiency, energy saving, safe and clean production. the manufacturing process and quality of stamping parts have a direct impact on the quality and cost of automobile manufacturing to a large extent.
