Sheet metal processing basic knowledge

Sheet metal processing is a sheet metal technicians need to master the key technologies, but also sheet metal forming an important process. Sheet metal processing includes both traditional cutting and blanking, blanking, bending and other methods and process parameters, but also includes a variety of cold stamping die structure and process parameters, a variety of equipment working principle and method of operation, including the new stamping technology And new technology. The company is located in:
Sheet metal processing is called sheet metal processing. For example, the use of sheet metal making chimneys, iron drums, fuel tanks, ventilation ducts, elbow size head, Tian Yuan place, funnel-shaped, sheet metal processing is the main process of cutting, bending deduction, bending, welding, riveting Etc., need some knowledge of geometry. Sheet metal is the sheet metal hardware, that is, by stamping, bending, stretching and other means to processing parts, a general definition is in the processing of the same thickness of the parts. Corresponding to the casting, forging, Machining parts and so on. Cold working usually refers to the metal cutting, that is, with cutting tools from the metal material (blank) or workpiece removal of excess metal layer, so that the workpiece obtained with a certain shape, dimensional accuracy and surface roughness of the processing methods. Such as turning, drilling, milling, planing, grinding, broaching and so on. In metalworking, in contrast to hot work, cold work refers to a process that causes plastic deformation of metals below recrystallization temperature, such as cold rolling, cold drawing, cold forging, stamping, cold extrusion and the like. Large cold deformation resistance, the metal forming the same time, you can use the work hardening to improve the hardness and strength of the workpiece, but will reduce the plasticity. Cold working for processing cross-sectional size, processing size and surface roughness of the higher metal parts.
