If the stamping is classified according to the process, it can be divided into two processes: forming and separating. The index of forming process is to make the sheet metal deform in the condition of no broken billet, and make the workpiece with the required shape and size. Separation process is also called blanking, the purpose is to make the stamping parts along the pre-set general situation from the sheet metal separation, while ensuring the quality requirements of the separation section.
In actual production, a variety of processes are often combined to operate on a workpiece. Blanking, straight, shear, spinning, replacement are often used stamping process. Stamping parts are mainly metal or non metal sheet, with the pressing pressure, by stamping die stamping forming, it has the following characteristics: 5 gold stamping sheet surface and extension to affect the quality of stamping scrap, stamping materials, uniform thickness for rough surface light, no; spot, no scar, no scratches, no surface crack; obey uniform strength, no taste preference; uniform stretch rate; low yield ratio; work hardening; stamping parts with high dimensional accuracy, the same module size is uniform and has good interchangeability.
Does not need further machining can meet the general requirements of assembly and use; stamping is based on material cost little, by punching out the parts of oppression, light weight, good stiffness, and plate material by plastic deformation, the layout structure of lost metal internal improvement, make stamping strength go ahead; stamping in the stamping process, because the material inside without crushing, it had better quality inside, outside can slide good-looking, this inner painting, plating, phosphating and disposal of any condition in addition inside supply.
