Furthermore, in the following detailed description of the present application, certain specific details are set forth in order to provide a better understanding of the present application. It will be apparent to one skilled in the art that the present application may be practiced without these specific details.
A top edge cambered surface structure of a passenger car according to an embodiment of the present application will be described in detail with reference to fig. 1 to 3. It is to be noted that the following examples are only for explaining the present application and do not constitute a limitation to the present application.
As shown in fig. 1, a top edge cambered surface structure of a passenger car comprises at least one framework, a cambered surface metal plate and a connecting auxiliary material;
a framework part: as shown in fig. 2 and 3, the frame part is composed of an upper longitudinal beam, a lower longitudinal beam and ribs, which are connected by welding to build a firm frame body. Go up the longeron, the longeron can select for use the quarter bend as required, section bars such as angle steel or L spare or groove box spare of bending, the rib adopts 3mm thick steel plate numerical control flame or laser cutting to form, radian and thickness are adjustable, can set up lightening hole and location, mounting hole on it, and 2mm thick, the wide cambered surface supporting surface board of 20mm is as the laminating holding surface with the panel beating in cambered surface side welding, it is great in batches to the section curve, also can adopt the part of 1mm thick suppression as the laminating holding surface. The section curve can be adjusted according to the product modeling requirement, and the number of the frameworks and the intervals for arranging the ribs can be reasonably selected according to the structural strength required by supporting.
Cambered surface panel beating: as shown in fig. 2, the cambered surface metal plate is generally made of a steel plate with a thickness of 1mm, the cambered surface metal plate is a plane part without radian before being combined with the framework, and an L-shaped roller edge or a Z-shaped roller edge can be adopted at one end or two ends of the cambered surface metal plate simultaneously so as to enhance the rigidity and reduce the deformation.
