Analysis:
Up to now, there is no complete definition of sheet metal. According to a definition in foreign professional journals, it can be defined as: sheet metal is a comprehensive cold working process for metal plates (usually less than 6mm), including cutting, punching/cutting/compounding, folding, welding, riveting, splicing and forming (such as automobile body). Its remarkable feature is that the thickness of the same part is consistent.
1. It is a processing method of automobile maintenance, also called cold working.
To put it bluntly, if the appearance of the car body is damaged and deformed, the sheet metal process is needed to restore the original appearance.
Basically, the tool used is a hammer. With hammers of different shapes, the iron block is placed behind the sheet metal part and hammered repeatedly to shape it.
If necessary, use the Appearance Restorer. This thing actually belongs to welding. Weld the iron ring on the car body and pull it out with the hook. Used to repair the sunken part.
The large flat body is usually difficult to put back in place, so it is sometimes used to turn off the fire. That is, local heating and cooling make the iron sheet shrink.
The ultimate goal is to restore the damaged body to its original appearance.
2. Sheet metal: Sheet metal, that is, plate and thin plate, refers to a series of processing of thin metal plates, including folding, cutting, punching, welding, riveting and splicing.
3. This is a design module, mainly aimed at things made of iron. It is different from the entity, the thickness of the entity has changed, but the sheet metal is basically the same thickness, and there are many products made of sheet metal in life.
Generally speaking, the basic equipment of a sheet metal factory includes shearing machine, CNC punch, laser, plasma, water jet cutting machine (laser, PLA * * * A), combined machine, bending machine, uncoiler, straightener, deburring machine and other auxiliary equipment.
Generally, the three most important steps in a sheet metal factory are cutting, stamping/cutting and folding.
