1. Technological Procedure

Sheet metal fabrication requires precise guidance and control. Common processes include raw material improvement, proofing, blanking, cutting, forming, assembly (welding, pressure riveting), etc. From the direction of nature, it can be summarized as material preparation, lofting and assembly.

Generally speaking, a large and complex sheet metal structure often needs to be completed with the cooperation of welders, lifting workers and other professional types of work. For the processing technology that is directly completed by pressure processing (such as presses, hydraulic presses, etc.), it’s often namely stamping; For the process that uses welding for component assembly, it’s namely welding.

2. Types of craftsmanship

A. PlasticForming

Sheet metal processing can also be subdivided into fine-grain plasticity, phase change plasticity and other plasticity in this respect. Among them, fine-grain plasticity is a widely used one, but the premise is that it needs to have a certain heat resistance stability. The denaturation temperature needs to be higher than that of the material. The melting point temperature is higher.

B. Laser Shock

The laser shock technology of sheet metal processing is to shock the laser beam to the metal surface in a pulsed manner, which can be used for cutting and other operations to make the material plastically denatured.

C. Hydro-forming

The hydraulic forming technology of sheet metal processing uses oil as the pressure transmission medium, and the hydraulic bladder is used to carry out two kinds of elastic dies or punches, and the forming is carried out through this operation and process.
