What is sheet metal?

Sheet metal parts are products processed by sheet metal technology. We cannot do without sheet metal parts everywhere in our lives. Sheet metal parts are made through filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, fine welding, roll forming, sheet metal bending, die forging, water jet cutting, and fine welding. maded.

A definition in a foreign journal can define sheet metal as: sheet metal is a comprehensive cold working process for metal sheets (usually below 6mm), including shearing, punching/cutting/compounding, folding, welding, riveting, and splicing , Forming (such as car body), etc. Its notable feature is the uniform thickness of the same part. Generally, the three important steps in a sheet metal factory are shearing, punching/cutting, and folding.

Sheet metal is sometimes also used as a metal plate. The word comes from the English platemetal. Generally, some metal sheets are plastically deformed by hand or die stamping to form the desired shape and size, and can be further welded or a small amount of machinery Processing to form more complex parts, such as chimneys, tin stoves, and car shells commonly used in homes are all metal parts.

Sheet metal processing is called sheet metal processing. Specifically, for example, the use of plates to make chimneys, iron barrels, fuel tanks, oil tanks, ventilation pipes, elbows, landscaping, funnels, etc. The main processes are cutting, bending, bending, forming, welding, riveting, etc. A certain geometric knowledge is required.

Sheet metal parts are thin sheet metal parts, that is, parts that can be processed by stamping, bending, stretching and other means. A general definition is-

Parts with constant thickness during processing. Corresponding to casting parts, forging parts, machining parts, etc., for example, the outer iron shell of a car is a sheet metal part, and some kitchen utensils made of stainless steel are also sheet metal parts.
