Structural characteristics of automobile stamping parts

Auto stamping parts, as the name suggests, are stamping parts used on cars. Generally speaking, stamping parts used in automobiles have very high precision requirements and must pass IATF16949 certification, which is a huge threshold for many stamping processing plants. Precision-Focus on custom processing of automotive stamping parts, with more than 10 years of experience. Next, we will introduce the structural characteristics of automotive stamping parts. 1. Large specifications. Automobiles are a large industrial product among daily necessities. Automobile stampings are parts that cover the diesel engine and the automobile chassis to form the automobile body. Therefore, the size of its structural specifications lies in the size of the car body layer. From the perspective of the role of stamping parts, the layering should be the bigger the better. Analyzed from the perspective of the overall production and manufacturing process performance of the car body, it should be the bigger the better. Therefore, the structural specifications of stamping parts are generally larger. 2. The sheet is thin. In order to better reduce the weight of the car itself, the plates used in the stamping parts are all relatively thin. Thickness is a relative definition. The ratio of the diameter (m) of the stamping parts to the thickness (mm) of the commonly used plate is generally above 1.00. The thickness of stamping parts is generally between 0.6mm and 1.2mm. 3. It looks complicated. In order to consider the use and beautiful appearance, automobile stamping parts are generally composed of three-dimensional standard inclined planes and irregular inclined planes composed of compound inclined planes. 4. Use the entity model to express. Because stamping parts are composed of three-dimensional inclined planes, it is very difficult to use CAD drawing to thoroughly describe the appearance and specifications of automobile stamping parts. It is generally indicated by a solid model. The solid model that shows the specifications of the automotive stamping parts is called the master model.
