The sheet metal process generally speaking, the basic devices include Shear Machine, CNC Punching Machine/laser, plasma, plasma, water -fired cutting machine, bending machine, drilling machine, and various types Auxiliary devices such as: opening machine, tienning machine, margin device, point welding machine, etc.  
 
Generally, the four most important steps of sheet metal process are shear, punch/cut/, fold/volume, welding, surface treatment, etc.  
 
The sheet metal is sometimes made of gold. The word comes from the English PlateMetal. Generally, some metal plates are stamped by manual or mold to produce plastic deformation, forming the hoping shape and size. Form more complicated parts, such as chimneys commonly used in families, iron furnaces, and car shells are sheet metal.  
 
Metal plate processing is called sheet metal processing. Specifically, for example, the use of plate materials to make chimneys, iron barrels, fuel tank fuel pots, ventilation pipes, elbow size heads, sky round places, funnel shapes, etc. The main processes are cutting, bending buckle, bending molding, welding, riveting, etc., need There must be geometric knowledge.  
 
The sheet metal parts is the shear hardware, that is, the parts that can be processed by stamping, bending, stretching and other means, a general definition is-  
During the processing process, the thickness of the thickness is corresponding to casting parts, forging components, mechanical processing parts, etc. For example, the iron shell outside the car is sheet metal parts, and some of the cabinets made by stainless steel are also sheet metal parts.  
 
Modern sheet metal crafts include: filament power winding, laser cutting, heavy processing, metal bonding, metal pull -out, plasma cutting, precision welding, rolling forming, metal plate bending molding, mold forging, water spray cutting, precision welding, etc. Essence  
 
The surface treatment of sheet metal is also a very important part of the sheet metal processing process because it has the effect of preventing parts from rusting and beautifying the appearance of the product. The role of the sheet metal on the surface of the sheet metal is mainly to remove oil, oxide, rust, etc. It is prepared for surface treatment, and then the processing is mainly sprayed (baking) paint, plastic spraying, and rust -proof layer.  
 
In 3D software, Solidworks, UG, Pro/E, SolidEdge, TopSolid, CATIA, etc. all have sheet metal pieces. Essence
