General classification of sheet metal materials


Sheet metal is one of the important crafts of hand plate. Do you know what kind of materials it has?
What are the methods?
Today we will discuss the classification of sheet metal stamping materials.

Method one:
1, black metal: all kinds of carbon steel, stainless steel.
A: Carbon structural steel (main grades: Q235, Q255, Q275).
Complex bending, stretching and forming parts.
Steel no. 10,45,70, etc.)
B: Alloy steel (main grades: D21, D22, D31, D41, D42, etc.) for the manufacture of special performance parts (such as: carbon steel plates, motors, electrical appliances, electronics) (stainless steel grades: 1CR13,2CR13,4CR13, etc.)
2. Non-ferrous metals: brass, bronze, red copper, hard aluminum, titanium alloy, etc.
A: Steel and copper alloy: pure copper, also known as red copper and electrolytic copper, T1, T2, T3, etc.
The alloy of copper and zinc is brass (H62, H68);
The alloy of aluminium and tin is bronze;
The alloys of copper, zinc, silicon and lead are wuxi bronze, collectively called bronze.
B: Aluminum and aluminum alloys: pure aluminum has excellent plasticity and conductivity. The order Numbers are L2, L3, L5 and L7.
Aluminium alloy is divided into cast aluminium alloy and deformed aluminium alloy.
3. Non-metallic materials: cardboard, plywood, rubber board, plastic, asbestos, etc.
 
 
Method 2:
1. Plate: electrolytic plate, cold-rolled plate, hot-rolled plate, galvanized plate, stainless steel, aluminum plate, copper plate, etc.
Sheet is the most widely used material in stamping processing, which can be divided into cold-rolled sheet and hot-rolled sheet.
Cold rolled plates are generally thin steel (plate thickness);
4 mm) Because the surface is smooth, smooth and the thickness tolerance is strict, so the stamping performance is better than hot rolled plate, hot rolled plate has thin steel plate and thick steel plate (plate thickness T>
4 mm) generally after pickling before stamping, in order to eliminate the steel plate surface oxide scale and rust.
The sheet is generally cut into long strips by the shearing machine, and the operator holds a piece of strip to feed gradually.
For some stamping parts, the operator's hand is required to assist the operation in the die during the stamping of the first or last part. This cannot be considered as a safe operation. In general, safety baffle should be installed to prevent the operator's hand from reaching into the die.
2. Strip (coil) : copper, aluminum, cold-rolled coil, galvanized coil, electrolytic plate coil, etc.
Strip is generally rolled out by rolling mill steel plate is not cut off, directly rolled into a cylinder, so the production process is less, the price is cheaper, less occupied area when storage.
In stamping process, the material needs to go through the uncoiling and multi-roll uncoiling leveling mechanism, can be unfolded, sent into the mold by the feeding mechanism.
Because the coil material ADAPTS to join the continuous stamping processing, the material utilization ratio is high, easy to mechanization and automation stamping, the security is good, help gradually widely used in the mass production of the specialized stamping processing.
3, profiles: aluminum profiles, copper profiles, plastic plate.
Profiles have cold drawn round steel, square steel, hexagonal steel, flat steel, etc., are rolled to the national standard.
Such as flat steel for more than 3-8 mm hot rolled steel plate, its features on both sides of the arc shape.
Profiles can also be supplied in accordance with the specific shape of the agreement, such as car wheel mesh and lock ring blank is supplied by steel mills in a specific shape of the steel plate.
