Sheet metal has not yet had a relatively complete definition. According to a definition in a foreign professional journal, it can be defined as: sheet metal is a comprehensive cold working process for metal sheets (usually below 6mm), including shearing and punching. , cutting, compounding, folding, welding, riveting, splicing, forming (such as car body). Its remarkable feature is that the same part concentration is consistent.
It is a processing method for car repair, also called cold work.
To be straightforward, if the appearance of the car body is damaged and deformed, the process of sheet metal is required to restore the original appearance.
The basic tool used is the hammer. Hammers of different shapes, with iron blocks behind the pieces, repeatedly tapped to make them shape.
Appearance repairers are also needed when necessary. This thing actually belongs to welding. Weld the iron ring on the body and pull it out with a hook. Used to repair the recessed parts.
A large flat body is generally difficult to get back, so sometimes it is used to close the fire. It is localized heating and cooling to shrink the iron sheet.
The ultimate goal is to restore the damaged body to its original appearance.
2. Sheet metal, that is, the meaning of the board, the thin plate, is the series of processing of thin metal sheets, including folding, shearing, punching, welding, riveting, splicing, etc.
3. This is a design module, mainly for the use of metal materials made of Dongdong. He is not the same as the entity, the concentration of the entity has changed, but the gold is basically the same concentration, there are many products made of sheet metal in life.
The basic equipment of the sheet metal factory generally includes a Shear Machine, a CNC Punching Machine, a laser, a plasma, a water jet cutting machine (Laser, Plasma, Waterjet Cutting Machine), a Combination Machine, Bending Machine and various auxiliary equipment such as uncoiler, leveling machine, deburring machine, spot welding machine, etc.
Usually, the three most important steps in a sheet metal factory are cutting, punching, cutting, and folding.
