Sheet metal parts have the characteristics of light weight, high strength, conductivity (can be used for electromagnetic shielding), low cost and good mass production performance, and have been widely used in electronic appliances, communications, automobile industry, medical devices and other fields. For example, computer case, mobile phone, MP3 player and sheet metal parts are all indispensable parts.
Life is inseparable from sheet metal parts. Sheet metal parts are made by filament winding, laser cutting, heavy machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending forming, die forging and water jet cutting.
Extended data
With the more and more extensive application of sheet metal, sheet metal design has become a very important part of product development. Mechanical engineers must master the design skills of sheet metal skillfully, so that the designed sheet metal can not only meet the requirements of product function and appearance, but also make the stamping die simple to manufacture and low in cost.
The base material of SECC is common cold-rolled steel coil. After degreasing, pickling, electroplating and various post-treatment processes, it becomes an electro-galvanized product.
SECC not only has the mechanical properties and approximate machinability of common cold-rolled steel plates, but also has excellent corrosion resistance and decorative appearance. It has great competitiveness and substitution in the markets of electronic products, household appliances and furniture. For example, SECC is widely used in computer chassis.
Modern sheet metal processes include filament winding, laser cutting, rework, metal bonding, metal stretching, plasma cutting, precision welding, roll forming, sheet metal bending forming, water jet cutting and so on.
In three-dimensional software, SolidWorks, UG, Pro/E, SolidEdge, TopSolid, etc. There is a sheet metal part, which mainly obtains the data needed for sheet metal processing (such as unfolded drawing, bending line, etc.). ) By editing 3D graphics and providing data for CNC punching machines, etc.
