Knowledge:
Sheet metal, a process, sheet metal has not yet been a more complete definition. According to a definition in a foreign professional journal, it can be defined as: sheet metal is a comprehensive cold working process for sheet metal (usually below 6mm), including shearing, punching / cutting / composite, folding, riveting, splicing, etc. To form (a car body, for example). Its remarkable feature is the same thickness of the same part.
Process characteristics
Sheet metal has the characteristics of light weight, high strength, electrical conductivity (which can be used for electromagnetic shielding), low cost, good mass production performance and so on. It has been widely used in the fields of electronics and appliances, communication, automobile industry, medical devices and so on. For example, in computer chassis, mobile phones, MP3, sheet metal is an essential component. With the increasing application of sheet metal, the design of sheet metal has become a very important part in the process of product development. Mechanical engineers must master the design skills of sheet metal. The designed sheet metal not only meets the requirements of the function and appearance of the product, but also makes the stamping die manufacture simple and low cost.
main application
There are many sheet metal materials suitable for stamping processing. The sheet metal materials widely used in the electronic and electrical industry include:
(1) ordinary cold rolled plate SPCC means that ingots are rolled continuously through a cold rolling mill into steel sheets or sheets of required thickness. There is no protection on the surface of SPCC and it is extremely vulnerable to oxidation when exposed to air, especially in wet environments. The appearance of dark red rust, when used, the surface should be sprayed, electroplating or other protection.
(2) the substrate of galvanized steel sheet SECC is common cold rolled steel coil. After the continuous galvanizing production line has been degreased, pickled, electroplated and all kinds of post-processing processes, She ECC not only has mechanical properties and similar processability of cold rolled steel sheet, but also has superior corrosion resistance and decorative appearance. In the electronic products, home appliances and furniture market has great competition and substitution. For example, the common use of computer chassis is SECC..
(3) Hot-dip galvanized steel sheet SGCC hot-dip galvanized steel coil refers to the semi-finished product of hot-rolled pickled or cold-rolled steel which is washed, annealed and immersed in a molten zinc bath at a temperature of about 460C, and the steel sheet is coated with zinc, After tempering and levelling and chemical treatment, SGCC materials are harder than SECC materials, poor ductility (avoid deep drawing design), thicker zinc layer and poor weldability.
(4)the content of SUS301 Cr in stainless steel is lower than that of SUS304, and its corrosion resistance is poor, but it can obtain good tensile force and hardness and good elasticity after cold working. It is more used in spring of shrapnel and anti-EMI..
(5) stainless steel SUS304 is one of the most widely used stainless steels, because Ni is richer than Cr steel in corrosion resistance, heat resistance, has very good mechanical properties, no heat treatment hardening phenomenon, no elasticity.
