Stamping parts are the forming process of the workpiece (stamping parts) of the desired shape and size, which is caused by the external force exerted by the press machine and the die on the sheet, strip, pipe and profile to produce plastic deformation or separation. Stamping and forging belong to plastic processing (or pressure processing). Blank of stamping mainly hot and cold rolled steel and steel strip.
The stamping components are mainly made of metal or non-metal sheet. With the help of the pressure of the press machine and through stamping die, they have the following characteristics:
Stamping parts are made by stamping on the premise of less material consumption. The parts are light in weight and good in stiffness. After plastic deformation of the sheet material, the internal structure of the metal is improved and the strength of stamping parts is improved.
Stamping parts have higher dimensional accuracy, uniform size of the same module, better interchangeability.general assembly and operation requirements can be met without further machining.
As the surface of the material is not damaged during the stamping process, the surface of the stamping tool has good surface quality and its appearance is smooth and beautiful, which provides convenient conditions for surface painting, plating, phosphating and other surface treatment.
