Briefly introduce the sheet metal process

Sheet  metal processes generally include basic equipment such as Shear  Machine, CNC Punching Machine, laser, plasma, cutting machine, bending  machine and various auxiliary equipment. Such as: uncoiler, leveling machine, deburring machine, spot welding machine, etc. In  general, the most important four steps of the sheet metal process are  shearing, punching, cutting, folding, rolling, welding, surface  treatment, and the like.

Sheet  metal is sometimes used as a gold plate. The word comes from the  English platemetal. Generally, some metal sheets are plastically  deformed by hand or die to form the desired shape and size, and can be  further welded or a small amount of machining. The  formation of more complex parts, such as the chimneys commonly used in  the home, the iron stove, and the car shell are all sheet metal parts.

Sheet  metal processing is called sheet metal processing, such as the use of  sheet metal to make chimneys, iron drums, fuel tank oil cans,  ventilation ducts, elbow heads, round spaces, funnels, etc. The main  process is to cut, bend and buckle, Bending, welding, riveting, etc. require a certain amount of geometric knowledge.

Sheet  metal parts are thin-plate hardware, that is, parts that can be  processed by means of stamping, bending, stretching, etc. A general  definition is a part with constant thickness during processing,  corresponding to casting parts, forging parts, Machining  parts, such as the outer iron shell of the car is a sheet metal part,  and some of the stainless steel cabinets are also sheet metal parts.

Modern  sheet metal processes include: filament power windings, laser cutting,  heavy machining, 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 effect of  preventing the parts from rusting and beautifying the appearance of the  product. The  surface pretreatment of sheet metal parts is mainly to remove oil,  scale, rust, etc., which prepares for surface post-treatment, and the  post-treatment is mainly spray (baked) paint, sprayed plastic and  rust-proof layer.

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 the processing of sheet metal parts (such  as unfolding, bending) Lines,  etc.) and provide data for CNC Punching Machines, Laser, Plasma,  Waterjet Cutting Machines, Combining Machines, and CNC Bending Machines.  .
