Sheet metal, a kind of processing technology, can be defined as: sheet metal is for the metal sheet (usually below 6mm) a comprehensive cold working process, including shearing, punching/cutting/compounding, folding, riveting, splicing, molding (e.g., automobile bodywork), etc.; its distinctive feature is that the same part thickness is consistent.

1, 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 machine, deburring machine, spot welding machine and so on. burring machine, spot welding machine, etc.

2. Usually, the four most important steps in the sheet metal process are shearing, punching/cutting/, folding/rolling, welding, surface treatment, etc.

3, sheet metal is sometimes also used as a wrench, the word comes from the English platemetal, generally some sheet metal by hand or mold stamping to produce plastic deformation, the formation of the desired shape and size, and can be further welded or a small amount of mechanical processing to form more complex parts, such as chimneys commonly used in the home, tin stove, and car shells are sheet metal parts.
3, sheet metal processing is called sheet metal processing. Specific such as the use of sheet metal to make chimneys, iron barrels, oil tanks, oil pots, ventilation pipes, elbows, elbows and heads, the sky and the round, funnel-shaped, etc., the main process is to shear, bending and buckling, bending, welding, riveting, etc., need a certain geometric knowledge.
4, sheet metal parts is sheet metal parts, that is, can be processed by stamping, bending, stretching and other means of parts, a general definition is -
In the process of processing the thickness of the parts remain unchanged. Corresponding to the casting parts, forging parts, machining parts, such as the outside of the car's iron shell is sheet metal parts, stainless steel to do some of the cabinet is also sheet metal parts.
5, modern sheet metal processes include: is a filament power winding, laser cutting, heavy-duty machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending molding, die forging, water jet cutting, precision welding and so on.
6, the surface treatment of sheet metal parts is also a very important part of the sheet metal processing process, because it has the role of preventing parts from rusting and beautifying the appearance of products. The role of surface pretreatment of sheet metal parts is mainly to remove oil, oxide, rust, etc., which prepares the surface for post-processing, which is mainly spraying (baking) paint, plastic spraying and rust plating.
7, 3D software, SolidWorks, UG, Pro / E, SolidEdge, TopSolid, CATIA, etc. have a sheet metal parts, mainly through the editing of 3D graphics and get the sheet metal parts processing data required (such as unfolding diagrams, bending lines, etc.) and for the numerical control punching machine (CNC Punching Machine) / laser, Plasma, water jet cutting machine (Laser, Plasma, Waterjet Cutting Machine) / Combination Machine (Combination Machine) and CNC Bending Machine (CNC Bending Machine), etc. to provide data.
