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 sheet metal (usually below 6mm), including cutting, punching/cutting/compounding, folding, welding, riveting, splicing, forming (such as car body). Its remarkable feature is the same thickness of the same part.

Sheet metal processing is called sheet metal processing. Specifically, for example, the use of plates to make chimneys, iron barrels, oil tanks, ventilation pipes, elbow sizes, day garden places, funnel shapes, etc., the main process is cutting, bending, bending, welding, riveting, etc., which requires certain geometric knowledge.

Sheet metal is sheet metal hardware, that is, parts that can be processed by stamping, bending, stretching and other means, a general definition is -

Parts whose thickness does not change during machining. Corresponding to casting parts, forging parts, machining parts, etc., such as the iron shell outside the car is sheet metal parts, and some cabinets made of stainless steel are sheet metal parts.

1. It is a processing method of automobile maintenance, also called cold doing.

Speaking directly, if the appearance of the body is damaged and deformed, the sheet metal process is needed to restore the original appearance.

Basically, the tool is a hammer. Hammers of different shapes place iron blocks behind the plate and repeatedly knock them to form them.

Use appearance restorers if necessary. This stuff actually belongs to welding. Weld the hoop to the body of the car and pull it out with the hook. Used to repair dented parts.

A large area of flat body is generally difficult to get back to the position, so sometimes it is also used to collect fire. It is locally heated and cooled to shrink the iron sheet.

The ultimate goal is to restore the damaged car body to its original appearance.

2. Sheet metal: plate, that is, plate, sheet means a series of processing of thin metal sheets, including folding, cutting, punching, welding, riveting, splicing and other processes

3. This is a design module, mainly for things made of iron sheet materials. He is not the same as the entity, the thickness of the entity has changed, but the sheet metal is basically the same thickness, and there are many products made with sheet metal in life.

In general, the basic equipment used in sheet metal includes Shear Machine (Shear Machine), CNC punching machine (CNCPunching Machine)/Laser,Plasma, water jet cutting machine (Laser,Plasma, water jet). Waterjet Cutting Machine (CombinationMachine), Bending Machine (Bending Machine) and various auxiliary equipment such as: uncoiler, leveling machine, deburring machine, spot welding machine, etc.
