Sheet metal is a processing technology, and sheet metal has not yet had a relatively complete definition. But according to a definition in a foreign professional journal, it can be defined as: Sheet metal is a comprehensive cold working process for thin metal plates (usually below 6mm), including shearing, punching, cutting, compounding, bending , riveted steel plate, spliced steel plate, forming (such as automobile body), etc. The characteristic of sheet metal is that the thickness of the same part is the same.
Sheet metal processing is also called metal sheet processing. For example, using sheets to make chimneys, iron drums, fuel tanks, ventilation ducts, elbows and heads, round places, funnels and other products, the main process of sheet metal processing is cutting, folding, etc. Bending, bending, welding, riveting, etc., the construction master must have a certain knowledge of geometry. Secondly, sheet metal has the characteristics of light weight, high strength, electrical 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. In computer cases, mobile phones, and MP3, sheet metal is an essential part.
As the application of sheet metal becomes more and more extensive, the design of sheet metal parts has become an important part of the product development process. Mechanical engineers must be proficient in the design skills of sheet metal parts, so that the designed sheet metal can meet the requirements of the product. Function and appearance requirements, but also make the stamping die easy to manufacture and low cost.
