Sheet metal has not yet had a relatively complete definition, the current relatively perfect definition is a comprehensive cold working process for sheet metal. According to a definition in a foreign professional journal, it can be defined as: Sheet metal is a comprehensive cold working process for metal sheets (usually below 6mm), including shearing, punching/cutting/compounding, folding, riveting, splicing, Forming (such as car body), etc. Its remarkable feature is that the thickness of the same part is the same. . Sheet metal has the characteristics of light weight, high strength, electrical conductivity, low cost, and good mass production performance. It has been widely used in the fields of electronic appliances, communications, automobile industry, medical equipment, etc. Sheet metal is an essential part of the process.
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. In addition, the basic equipment of sheet metal includes shearing machine, CNC punching machine, laser, plasma, water jet cutting machine, bending machine, drilling machine and various auxiliary equipment.
