Simply put, the outer iron shell of the car is the car sheet metal. 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), etc.Dalian sheet metal partsTo tell you, its distinguishing feature is the same thickness of the same part.

Dalian sheet metal partsSaid that the basic equipment for sheet metal processing generally includes shears, CNC punch lasers, plasma, water jet cutting machines, bending machines, drilling machines, and various auxiliary equipment such as: uncoilers, leveling machines, deburring machines, and dots. Welder etc. Generally, the four important steps of sheet metal process Z are shearing, punching/cutting/, folding/rolling, welding, surface treatment and so on.

Sheet metal is sometimes used as a metal plate. The word comes from the English platemetal. Generally, some metal sheets are plastically deformed by hand or die stamping to form the desired shape and size, and can be further processed by welding or a small amount of machining. Forming more complex parts, such as chimneys, tin stoves, and car shells commonly used in homes are all sheet metal parts.

Modern sheet metal technology includes: filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending, die forging, water jet cutting, precision welding, etc. .

Sheet metal has the characteristics of light weight, high strength, electrical conductivity (can be used for electromagnetic shielding), low cost, and good mass production performance. It has been widely used in electronic appliances, communications, automotive industry, medical equipment and other fields, such as in In computer cases, mobile phones, and MP3, sheet metal is an indispensable part.

As the application of sheet metal becomes more and more widespread, the design of sheet metal parts has become a very important part of the product development process. Mechanical engineers must be proficient in the design skills of sheet metal parts, so that the designed sheet metal meets the requirements of the product. The requirements of function and appearance can make the stamping die manufacturing simple and low cost.
