Sheet metal parts refer to the processing of metal sheets into parts with specific shapes and sizes through cold working of metal materials, cutting, bending, stamping, welding and other processes. Sheet metal parts are widely used in modern manufacturing, covering various fields, including automobile manufacturing, electronic equipment, aerospace and so on.
Classification of sheet metal parts
Sheet metal parts can be classified according to their use, shape and processing technology. The following are common sheet metal part classifications:
1. Classification by purpose:
(1) Structural parts: mainly used to support, connect or protect other parts, such as frames, brackets, etc.
(2) Shell parts: used to wrap and protect internal components of products, such as electronic product shells, car bodies, etc.
(3) Accessories: used as accessories of other products, such as electrical accessories, auto parts, etc.
2. Classified by shape:
(1) Flat parts: simple in shape, usually processed from a flat metal plate, such as steel plate, aluminum plate, etc.
(2) Bending parts: made by bending sheet metal into a certain angle or curve shape, such as angle iron, guardrail, etc.
(3) Stamping parts: parts formed by continuous stamping on a metal plate through a stamping process, such as gears, racks, etc.
(4) Deep drawn parts: use the stamping process to stamp flat parts into parts with a certain depth, such as pots, sinks, etc.
3. Classified by processing technology:
(1) Cutting: Cut the metal sheet according to a specific shape and size. Common methods include shearing, flame cutting, laser cutting, etc.
(2) Bending: By exerting force on the metal sheet, it produces bending deformation. The commonly used methods are manual bending and mechanical bending.
(3) Stamping: Continuous stamping is carried out on the metal sheet through a mold to form the desired shape, which is often used in mass production.
(4) Welding: Joining two or more metal sheets together by melting or pressing.
Sheet metal forming method
Sheet metal forming refers to the processing of metal sheets to form them into parts with specific shapes. There are many methods of sheet metal forming, the following will introduce several common methods:
1. Shear forming: Shearing is the method of cutting sheet metal to the desired shape and size. Common shearing equipment includes manual shears, hydraulic shears, etc.
2. Bending forming: the metal sheet is bent and deformed by applying force, so as to obtain the desired angle and curve shape. Commonly used equipment for mechanical bending includes bending machines, plate rolling machines, etc.
3. Stamping forming: Stamping is to place the metal sheet between the stamping dies, and through the continuous stamping of the dies, the sheet is gradually formed. Stamping is a common method for mass production of sheet metal parts.
4. Deep drawn forming: deep drawn is to place the metal sheet in the mold and form it into a part with a certain depth through the stretching effect of the mold.
5. Laser cutting and forming: Laser cutting is a method of cutting metal sheets with laser beams, which can realize the forming of complex shapes.
6. Welding and forming: Two or more metal sheets are joined together by welding to form the required parts.
The choice of sheet metal forming method depends on the shape, size, material, and production needs of the part. In practical applications, multiple forming methods are often combined to complete the processing of complex parts through multiple processes.
Sheet metal parts are an indispensable part of modern manufacturing and are widely used in various fields. Sheet metal parts can be classified according to their use, shape and processing technology. Common forming methods include shearing, bending, stamping, laser cutting and welding.
Different sheet metal forming methods have their own advantages in different scenarios, and manufacturers need to choose the appropriate processing method according to actual needs. With the continuous advancement of science and technology, sheet metal processing technology is also constantly innovating and improving, bringing more possibilities for the development of the manufacturing industry.
