What are the characteristics and modeling requirements for automobile sheet metal parts?
2020-07-21 11:34:24

Automobile sheet metal parts are widely used in mechanical and electrical, light industry, automobile and other industries. In the past, the traditional production methods, due to the disadvantages of long cycle, low efficiency, poor quality and so on, have become increasingly unsuitable for modern design requirements. In order to overcome these disadvantages, people have developed some advanced CAD systems, such as parametric technolo G company's prosheetmal, integraph company flatpatternand nesting, etc., these special sheet metal parts design systems, although very powerful, but because most of them run on workstations, both software and hardware are very expensive, therefore, the development of sheet metal parts on Microcomputers CAD system is very meaningful.


Automobile sheet metal parts


The characteristics of sheet metal parts generally can be divided into three categories:

(1) Flat type refers to general plane blanking parts.

(2) A part consisting of bending or bending plus simple forming.

(3) Forming parts are regular surface or free-form surface parts processed by drawing and other forming methods. These parts are all processed by punching and deformation of plate blank. They are quite different from the parts processed by general machining methods.

In the processing mode of automobile stamping parts, bending deformation is the main processing mode which makes the sheet metal parts have complex spatial relationship. Other processing methods generally only produce bulges or depressions, notches, holes and edges on the plate. This feature must be paid attention to when establishing the modeling system of sheet metal parts.

In the process of die design, the shape of sheet metal parts is the main basis of die design, which determines the overall structure and shape of the die. The dimensional tolerance of sheet metal parts affects the dimension and tolerance of the working part of the die (such as convex and concave die). In addition, the material, geometrical tolerance and technical requirements of sheet metal parts have a great influence on the working parts of the die.

Therefore, the sheet metal part model should contain not only the shape information, but also the dimensional tolerance, accuracy, material and technical requirements of the part, so as to ensure the accuracy of the die design results. Sheet metal part model is the carrier of all kinds of information required by the subsequent die design application, which requires that the part model can reflect the characteristics of sheet metal parts, specifically, the engineering semantics of sheet metal parts, so that the die design application can understand and easily extract the required information. On the other hand, 3D sheet metal parts generally have complex spatial and positional relationships. Only according to the shape characteristics of sheet metal parts, it can simplify user operations.
