Sheet metal parts are products processed by sheet metal technology, and daily life is inseparable from sheet metal parts. Sheet metal parts are manufactured by filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, metal sheet bending, die forging, water jet cutting, precision welding .
Sheet metal is a comprehensive cold working process for metal sheets (usually below 6mm), including shearing, punching / cutting / compositing, folding, welding, riveting, splicing, forming (such as car body), etc. Its remarkable feature is the same thickness of the same part.
Sheet metal parts have the characteristics of light weight, high strength, electrical conductivity (can be used for electromagnetic shielding), low cost, and good mass production performance. They are widely used in electronic appliances, communications, automotive industry, and other fields, such as computers In the case, mobile phone, MP3, sheet metal parts are indispensable components.
Currently commonly used 3D CAD software, such as SolidWorks, UG, Pro / E, SolidEdge, TopSolid, etc., have a sheet metal part, mainly by editing 3D graphics to obtain the data required for sheet metal processing (such as expanded view , Bending line, etc.) and provide data for CNC punch / laser, plasma, water jet cutting machine compound machine and CNC bending machine.
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 design of sheet metal meets the requirements of the product. Requirements such as function and appearance can make stamping die manufacturing simple and low cost.
