sheet metal bending

0.00 ~ 0.00

Bending and forming of sheet metal is carried out on the plate bending machine, will be molding artifacts that are placed on the plate bending machine, use lifting lever lift brake shoe, workpiece slide into place, and then cut brake shoe to forming the workpieces by applying pressure on the plate bending machine bending lever and metal bending forming. The minimum bending radius is a function of the ductility and thickness of the formed metal. For aluminum, metal bending radius is greater than the thickness of the plate. When bending, the metal should be bent at a slightly larger Angle than required because of a certain springback.

There are many sheet metal materials suitable for stamping processing. Sheet metal materials widely used in the electronic and electrical industry include:

1. The ordinary cold-rolled plate SPCC SPCC refers to the ingot through the cold rolling machine continuously rolling into the required thickness of steel coil or sheet material. SPCC surface does not have any protection, it is easy to be oxidized when exposed to air, especially in the humid environment, the oxidation speed is accelerated, and dark red rust appears. When using, the surface should be painted, electroplated, or other protection.

2.The substrate of galvanized steel sheet SECCSECC is the general cold-rolled steel coil. After the degreasing, pickling, electroplating, and various post-treatment processes in the continuous electrogalvanizing production line, SECCSECC becomes the electro galvanized product. SECC not only has the mechanical properties and similar machinability of general cold rolled steel sheet, but also has superior corrosion resistance and decorative appearance. In the electronic products, home appliances and furniture of the market has great competitiveness and replacement. For example, SECC is commonly used for computer cases.

3.Hot-dip galvanized steel SGCC hot-dip galvanized steel coil refers to the semi-finished product of hot-rolled pickling or cold rolling, after cleaning, annealing, immersed in the temperature of 460°C molten zinc bath, the steel sheet coated with zinc, and then after quenching and tempering leveling and chemical treatment. SGCC materials are harder than SECC materials, less ductile (avoid deep drawing designs), thicker zinc layers, and less weldable.

4.The content of stainless steel SUS301Cr (chromium) is lower than SUS304, and the corrosion resistance is poor. But after cold working, it can obtain good tensile force and hardness, and good elasticity. It is mostly used for spring and anti-EMI.

5, stainless steel SUS304 is one of the most widely used stainless steel, containing Ni (nickel) than containing Cr (chromium) steel is rich in corrosion resistance, heat resistance, with very good mechanical properties, no heat treatment hardening phenomenon, no elasticity. sheet metal bending,,sheet metal bending,metal brake,sheet metal brake,sheet metal folder,metal brake for sale,box and pan brake
