What exactly is sheet metal in a sheet metal factory

Sheet metal processing is a key technology that sheet metal technicians need to grasp, and it is also an important process of sheet metal product forming.

Sheet metal processing is called sheet metal processing. Specifically, for example, the use of sheet metal to make chimneys, iron barrels, oil tanks, ventilation pipes, elbow size, sky round place, funnel shape, etc., the main processes are shearing, bending edge, bending forming, welding, riveting, etc., which requires certain geometric knowledge.

Sheet metal is sheet metal hardware, that is, can be processed by stamping, bending, stretching and other means of parts, a general definition is the thickness of the parts in the process of processing.

Corresponding to the casting parts, forging parts, machined parts and so on.

Sheet metal processing is a key technology that sheet metal technicians need to grasp, and it is also an important process of sheet metal product forming.

Sheet metal processing includes traditional cutting, blanking, bending forming and other methods and technological parameters, including a variety of cold stamping die structure and technological parameters, a variety of equipment working principle and control methods, but also includes new stamping technology and new process.

Problems in sheet metal processing

Strong hardening effect, large rebound, poor freezing performance of stamping parts, resulting in low accuracy of workpiece size and shape.

Stainless steel generates heat in plastic deformation, and its thermal conductivity is poor, so that the temperature of steel plate workpiece and die rises, the temperature can reach about 20℃, which is also one of the important reasons for adhesion, mold wear, workpiece scratch.

3, stainless steel has viscosity. After stamping deformation, the hardness of stainless steel is significantly improved, in the process of continued deformation, the material and the surface of the mold is easy to glue together at some points due to the great unit pressure, which intensifies the wear of the mold, the workpiece surface is also scratch, seriously affecting the service life of the mold and the quality of the stamping parts.

4, cold pressing work hardening ability is high, when the plastic deformation of austenitic steel, because the mechanical driving force partially or completely replaces the chemical driving force, the free energy of austenite and martensite has changed, that is, induced the transformation of austenite to martensite, the material work hardening, the deformation tension increased.
