Automobile stamping parts are the parts that cover the diesel engine and automobile chassis to form the car body. Therefore, the size of its structural specification lies in the size of the car's body layer. From the perspective of the function of the stamping part itself, the layering should be as big as possible. From the perspective of the overall manufacturing process performance of the car body, the bigger the better. Therefore, the structural specifications of stamping parts are generally relatively large.
In order to better alleviate the weight of the car itself, the plates used for stamping parts are relatively thin. Thickness is a relative definition. The ratio of the diameter (meter) of the stamping part to the thickness (mm) of the commonly used sheet is generally above 1.00. The thickness of stamping parts is generally between 0.6mm and 1.2mm.
In order to consider the use and appearance, automobile stamping parts are generally composed of three-dimensional standard inclined planes and irregular inclined planes.
Because the stamping parts are composed of three-dimensional inclined planes, it is very difficult to use CAD drawing to completely describe the appearance and specifications of automobile stamping parts. Generally, it is indicated by the entity model. The solid model that shows the appearance specification of the automobile stamping part is called the main model.
