Sheet metal is a process of sheet metal.
Sheet metal is designed for cold processing of sheet metal with a thickness of 6mm or less, including shearing, punching/cutting/compounding, folding, riveting, splicing, molding (such as automobile bodywork), and so on, with the distinctive feature that the same part is of the same thickness.
Sheet metal is characterized by light weight, high strength, conductive (able to be used for electromagnetic shielding), low cost, good mass production performance, etc., in the field of electronic and electrical appliances, communications, automotive industry, medical equipment and other fields have been widely used, for example, in the computer chassis, cell phones, MP3, sheet metal is an essential component. The design of sheet metal parts has become a very important part of the product development process, and mechanical engineers must be skilled in the design of sheet metal parts.
Sheet metal material introduction
1, hot-dip galvanized steel SGCC
Hot-dip galvanized steel coil refers to the hot-rolled pickling or cold-rolled semi-finished products, after cleaning, annealing, immersed in a temperature of about 460 ° C molten zinc tank, so that the steel sheet plated with zinc, and then by the tempering of leveling and chemical treatment and become. SGCC SGCC material is harder than SECC material, less ductile (to avoid deep drawing design), thicker zinc layer, and poorer weldability.
2, stainless steel SUS301
Chromium content is lower than SUS304, corrosion resistance is poor, but after cold processing can get very good tensile strength and hardness, elasticity is better, and is used for slug springs and anti-EMI.
3, stainless steel SUS304
Widest use of one of the stainless steel, because of the nickel content is rich than the chromium-containing steel. Corrosion resistance, heat resistance, has very good mechanical properties, no heat treatment hardening phenomenon, no elasticity.
