Quality characteristics of automobile stamping parts

Automotive stamping parts are a specific industry application of metal stamping parts, which play a very important role in the automotive industry. Generally speaking, automobile stamping parts have the advantages of high dimensional accuracy, strict surface quality requirements, strong structural rigidity and good processing technology. Next, precision will be analyzed and introduced from these points. 1. High-precision specifications. When it is connected, it is an inclined plane. At the turning point, of course smoothly. After the stamping part and the stamping part rebar are overlapped, the overlap surface of the two rebars is one surface, which caters to each other without gaps. The assembled and welded car body should become a work of art for people to appreciate. 2. Strict surface requirements. The automobile stamping parts visualize the appearance quality of the car. In addition to the high roughness requirements, it also stipulates that the convex lines on the stamping parts are clear and tidy, smooth and clean, up and down symmetry, symmetrical connection, smooth butt, and the inclined surface is connected to the main bridge. The surface layer is not allowed to have defects such as wavy lines, wrinkles, pits, pull marks, scratches, knocks and other damage to the surface layer. 3. Strong structural rigidity. Whether it is the cab of a light-duty truck or the body of a passenger vehicle, the stamping parts that make up them must have sufficient rigidity. Especially car body parts without beam structure, their compressive strength and rigidity are strong. Insufficient rigidity will not only cause deformation of the entire car body, but also cause noise when the car is running. 4. The processing technology is good. The key to excellent process performance refers to the feasibility analysis of one-time stamping die forming. The whole process of manufacturing and processing automobile stamping parts is very complicated. Stamping dies are very expensive. Excellent stamping die design can not only simplify the design of stamping die, but also greatly reduce the capital allocation for die production and manufacturing.
