Sheet metal is a comprehensive cold working process for thin metal sheets (usually under 6mm), including shearing, punching/cutting/compounding, splicing, molding (e.g., car body), etc. The sheet metal process is characterized by the consistent thickness of the same part. Its distinctive feature is the consistent thickness of the same part.
Sheet metal parts are characterized by light weight, high strength, conductive (able to be used for electromagnetic shielding), low cost, and good performance in large-scale mass production, etc. They are widely used in the fields of electronics and electrical appliances, communications, automotive industry, medical devices, etc. For example, in computer chassis, cell phones, MP3s, sheet metal parts are an essential component.
Life is inseparable from sheet metal parts everywhere. Sheet metal parts are made by filament power winding, laser cutting, heavy duty machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending and forming, die forging, and water jet cutting.
Expanded Information
With the increasing application of sheet metal, the design of sheet metal parts has become an important part of the product development process, and mechanical engineers must be proficient in the design of sheet metal parts to make the design of the sheet metal to meet the functionality of the product and the appearance of the product and other requirements, and also to make the stamping die manufacturing is simple and low cost.
The base material of SECC is a general cold rolled steel coil, which is degreased, pickled, plated, and post-treated in a continuous zinc plating line to become an electro-galvanized product.
SECC not only has the mechanical properties and similar processability of general cold rolled steel sheets, but also has superior corrosion resistance and decorative appearance. In the market of electronic products, home appliances and furniture, it has great competitiveness and substitutability. For example, computer chassis commonly used is SECC.
Modern sheet metal processes include: is filament power winding, laser cutting, heavy-duty machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending molding, water jet cutting.
3D software, SolidWorks, UG, Pro/E, SolidEdge, TopSolid, etc. have a sheet metal parts, mainly through the editing of 3D graphics and get the data required for sheet metal parts processing (such as unfolding diagrams, bending lines, etc.) as well as for the numerical control punching machine (CNC Punching Machine), etc. to provide data.
