Generally speaking, the basic equipment of sheet metal process includes shearing machine, CNC punch / laser, plasma, water jet cutting machine, bending machine and various auxiliary equipment such as uncoiler, leveling machine, deburring machine, spot welder, etc. The most important four steps of sheet metal process are: cutting, punching / cutting, folding, welding, surface treatment, etc.

Sheet metal is sometimes used as trigger gold. Generally, some metal sheets are pressed by hand or die to produce plastic deformation, forming the desired shape and size, and further forming more complex parts through welding or a small amount of machining, such as the commonly used chimneys in families, tin furnaces, and automobile shells are sheet metal parts.

Sheet metal processing is called sheet metal processing. For example, making chimneys, iron buckets, oil tanks, ventilation pipes, elbows, round places, funnel-shaped, etc. by using plates, the main processes are cutting, bending and buckling, bending and forming, welding, riveting, etc., which requires certain geometric knowledge.

Sheet metal parts are sheet metal parts, which can be processed by stamping, bending, stretching and other means. A general definition is the parts with constant thickness in the process of processing. The corresponding parts are casting parts, forging parts, machining parts, etc. for example, the iron shell outside the car is a sheet metal part, and some cabinets made of stainless steel are also sheet metal parts.

 

Modern sheet metal technology includes: filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, metal plate bending forming, die forging, water jet cutting, precision welding, etc.

 

The surface treatment of sheet metal parts is also a very important part of the sheet metal processing process, because it can prevent parts from rusting and beautify the appearance of products. The function of surface pretreatment of sheet metal parts is mainly to remove oil, oxide skin, rust, etc. it is to prepare for surface post-treatment, and the latter treatment is mainly to spray (bake) paint, spray plastic and plating antirust layer, etc.
