Generally speaking, the basic equipment for sheet metal processing includes shearing machines, CNC punching machines/lasers, plasma, waterjet cutting machines, bending machines, as well as various auxiliary equipment such as unwinding machines, leveling machines, deburring machines, spot welding machines, etc.
Modern sheet metal technology includes: filament power winding, laser cutting, heavy-duty processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, metal sheet 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, as it has the functions of preventing parts from rusting and beautifying the appearance of products. The main function of surface pre-treatment for sheet metal parts is to remove oil stains, oxide scales, rust, etc. It prepares for surface post-treatment, which mainly includes spraying (baking) paint, spraying plastic, and plating anti rust layers.
In 3D software, SolidWorks, UG, Pro/E, SolidEdge, TopSolid, CATIA, etc. all have sheet metal parts, which mainly obtain the data required for sheet metal processing (such as unfolded drawings, bending lines, etc.) through editing 3D graphics, and provide data for CNC punching machines/laser, plasma, waterjet cutting machines/combination machines, CNC bending machines, etc.
Sheet metal processing is called sheet metal processing. For example, using sheet metal to make chimneys, iron drums, oil tanks and pots, ventilation ducts, elbow heads, round corners, funnel-shaped structures, etc., the main processes are cutting, bending edges, bending forming, welding, riveting, etc., which require a certain amount of geometric knowledge. Sheet metal parts are thin metal parts that can be processed through stamping, bending, stretching, and other methods. A general definition is parts with constant thickness during the processing.
