Sheet metal processing is the key technology that sheet metal technicians need to master, and it is also an important process of sheet metal forming. Sheet metal processing includes traditional cutting, blanking, bending stamping and other methods and process parameters, as well as various cold stamping die structure and process parameters, the working principle and operation method of various equipment, as well as new stamping technology and new process. Sheet metal processing is called sheet metal processing.

What are the commonly used materials for sheet metal processing? Let's take a brief analysis.

1. Galvanized steel sheet SECC. The base material of SECC is ordinary cold-rolled steel coil, which becomes electro-galvanized product after degreasing, pickling, electroplating and various post-processing processes on the continuous electro-galvanized production line. SECC not only has the mechanical properties and similar processing properties of ordinary cold-rolled steel plates, but also has superior corrosion resistance and decorative appearance. It has strong competitiveness and substitutability in the electronic products, household appliances and furniture markets. For example, SECC is widely used in computer chassis.

2. Ordinary cold rolled sheet SPCC. SPCC refers to the continuous rolling of steel ingots into steel coils or plates of the required thickness with a cold rolling mill. SPCC surface without any protection, exposed to the air is easy to oxidize, especially in a humid environment, the oxidation rate is accelerated, and dark red rust appears. When used, the surface should be painted, plated or otherwise protected.

3. Hot-dip galvanized steel SGCC. Hot-dip galvanized steel coil refers to a semi-finished product after hot-rolled, pickled or cold-rolled. After washing and annealing, it is immersed in a molten zinc bath with a temperature of about 460°C, and then galvanized, tempered, leveled, and chemically treated. SGCC material It is harder than SECC material, has poor ductility (avoid deep drawing design), thicker zinc layer and poor weldability.

4. Stainless steel SUS304. As one of the widely used stainless steels, because it contains Ni (nickel), it is more corrosion resistant and heat resistant than steel containing Cr (chromium). It has very good mechanical properties, no heat treatment hardening, no elasticity.

5. Stainless steel SUS301.Cr (chromium) content is lower than SUS304, corrosion resistance is poor, but after cold working in the stamping can obtain good tensile strength, hardness and elasticity, used for spring spring and anti EMI.

Sheet metal processing is called sheet metal processing. So, what are the technical characteristics of sheet metal processing? Let's take a brief analysis.

1. High power density of sheet metal processing: The workpiece absorbs the rapidly rising temperature after sheet metal processing and melts or vaporizes. Even materials with high melting point, high hardness and high brittleness (such as ceramics, diamond, etc.) can also be processed with sheet metal.

2. The beam of sheet metal processing is easy to control: it is easy to combine with precision machinery, precision measurement technology and electronic computer to achieve high automation and high processing accuracy; 3. sheet metal processing is convenient and flexible. Robots can process metal plates in harsh environments or places that are difficult for others to access.

4. Wide application range of sheet metal processing: the beam divergence angle of sheet metal processing can be less than 1 milliradian, the spot diameter can be as small as microns, and the action time can be as short as nanoseconds and picoseconds. At the same time, the continuous output power of high-power sheet metal processing can reach the order of kilowatts to ten kilowatts.
