Sheet metal is pronounced bǎn jīn.
Sheet metal, a kind of machining process, sheet metal has not yet had a more complete definition. According to a definition in a foreign professional journal, it can be defined as: sheet metal is for sheet metal (usually below 6mm) a comprehensive cold working process, including shearing, punching/cutting/compounding, folding, riveting, splicing, molding (such as automobile bodywork) and so on.
The distinctive feature is the consistent thickness of the same part. Explanation from the Modern Chinese Dictionary (5th edition) - Sheet metal: verb, to work on sheet metal such as steel, aluminum, and copper. Sheet metal is characterized by light weight, high strength, conductivity (able to be used for electromagnetic shielding), low cost, and good mass production performance.
It has been widely used in the fields of electronic and electrical appliances, communications, automotive industry, medical equipment, etc. For example, sheet metal is an essential component in computer cases, cell phones, and MP3s. As the application of sheet metal becomes more and more extensive, the design of sheet metal parts becomes a very important part of the product development process.
Mechanical engineers must be skilled in the design of sheet metal parts, so that the design of the sheet metal not only to meet the functionality and appearance of the product and other requirements, but also make the stamping die manufacturing simple, low cost.
Sheet metal process in general, the basic equipment, including shearing machine (Shear Machine), CNC Punching Machine (CNC Punching Machine) / laser, plasma, water jet cutting machine (Cutting Machine), bending machine (Bending Machine), drilling machine, and a variety of auxiliary equipment, such as: uncoiler, Leveling Machines, Deburring Machines, Spot Welding Machines, and so on.
Usually, the four most important steps in the sheet metal process are shearing, punching/cutting/, bending/coiling, welding and surface treatment.
Sheet metal is sometimes also known as wrenching, the word comes from the English platemetal, generally some sheet metal by hand or mold stamping to make plastic deformation, forming the desired shape and size, and can be further through welding or a small amount of machining to form more complex parts, such as chimneys commonly used in the home, tin stove, and car shells are sheet metal parts.
Sheet metal processing is called sheet metal processing. Specifically, such as the use of sheet metal production chimneys, barrels, oil tanks, oil pots, ventilation pipes, elbows, elbow size head, the sky and the round, funnel-shaped, etc., the main process is to shear, bending, buckling, bending, welding, riveting, and so on, need to be certain geometric knowledge.
