The basis of sheet metal technology

Generally speaking, the basic equipment of sheet metal process includes Shear Machine, CNC Punching Machine/Laser, Plasma, Waterjet Cutting Machine, Bending Machine and various auxiliary equipment Such as: decoiler, leveling machine, deburring machine, spot welding machine, etc.

Generally, the four most important steps in the sheet metal process are shearing, punching/cutting, folding, welding, and surface treatment.

Sheet metal is sometimes 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 processed by welding or a small amount of machining Form more complex parts, such as the chimney commonly used in homes, iron stoves, and car shells are all sheet 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, sizes, rounds, funnels, etc. The main processes are shearing, bending, bending, forming, welding, and riveting Certain geometric knowledge.

Sheet metal parts are thin 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 castings, forgings, machining parts, etc., for example, the outer iron shell of a car is sheet metal, and some kitchen utensils made of stainless steel are also sheet metal.

Modern sheet metal processes include: filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending, 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 has the functions of preventing parts from rusting and beautifying the appearance of products. The surface pretreatment of sheet metal parts is mainly to remove oil, oxide scale, rust, etc. It prepares for the surface post-treatment, and the post-treatment is mainly spray (baking) paint, plastic spray and anti-rust coating.

In 3D software, SolidWorks, UG, Pro/E, SolidEdge, TopSolid, CATIA, etc. all have sheet metal parts, mainly through the editing of 3D graphics to obtain the data required for sheet metal processing (such as unfolded drawings, bending Line, etc.) and provide data for CNC Punching Machine/Laser, Plasma, Waterjet Cutting Machine (Laser, Plasma, Waterjet Cutting Machine)/Combination Machine and CNC Bending Machine, etc. .
