, a processing technology, has not yet had a relatively complete definition of Blech. According to a definition in a foreign professional journal, it can be defined as: Blech
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 notable feature is the uniform thickness of the same part.
Process characteristics of Blech
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, cell phones, and MP3, Blech is an indispensable part. As the application of Blech becomes more and more extensive, the design of Blech
parts has become a very important part of the product development process. Mechanical engineers must be proficient in the design skills of Blech parts, so that the designed Blech meets the product requirements. The function and appearance requirements can make the stamping die manufacturing simple and low cost.
