Sheet metal (Metal Plate;; SheetMetal), a processing technology, has not been completely defined so far. According to a definition in a foreign professional journal, it can be defined as: sheet metal is a comprehensive cold working process for sheet metal (usually less than 6mm), including shearing, punching/cutting/compounding, folding, riveting, splicing, forming (such as automobile body), etc. Its remarkable feature is that the thickness of the same part is consistent.
Sheet metal has the characteristics of light weight, high strength, conductivity (can be used for electromagnetic shielding), low cost, and good mass production performance. It has been widely used in electronic appliances, communications, automotive industry, medical equipment and other fields. For example, in computer chassis, mobile phones, MP3, sheet metal is an essential component.
With the application of sheet metal becoming more and more extensive, the design of sheet metal parts has become a very important part of the product development process. Mechanical engineers must master the design skills of sheet metal parts, so that the designed sheet metal can not only meet the requirements of product function and appearance, but also make the manufacturing of stamping dies simple and low cost.
Based on the above reasons, it is very necessary to systemically sort out the data on the structural design of sheet metal parts, and I believe that it will have some effect on the users of the rapid addition screen.
Structural design knowledge I of sheet metal parts:
The so-called thin plate refers to a steel plate whose thickness is much smaller than its length and width. Its lateral bending resistance is poor, so it is not suitable for the occasion under lateral bending load. Thin plate is metal in terms of its material, but because of its special geometric shape and small thickness, the processing technology of thin plate components has its particularity. There are three types of processing
technologies related to thin plate components:
(1) Blanking: it includes shearing and blanking.
(2) Forming: it includes bending, folding, curling and deep drawing.
(3) Connection: it includes welding, bonding, etc. The structural design of thin plate components shall mainly consider the requirements and
characteristics of processing technology.
In addition, pay attention to the batch size of components.
Thin plate members are widely used because thin plates have the following advantages:
(1) . It is easy to deform. In this way, various forms of components can be manufactured by simple processing technology.
(2) The thin plate component is light in weight.
(3) The processing amount is small. Because of the high surface quality of the sheet and the small dimensional tolerance in the thickness direction, the sheet does not need to be processed.
(4) It is easy to cut and weld, and can manufacture large and complex components.
(5) The shape is standardized for automatic processing.
