The customized stamping parts are a forming method for obtaining a workpiece (stamping part) of the desired shape and size by applying an external force to the plate, the strip, the pipe and the profile by the press and the mold to cause plastic deformation or separation. Stamping and forging are the same plastic processing (or pressure processing), collectively forging. Stamping blanks are mainly hot and cold rolled steel and steel.
The world's steel, there are 60 to 70% of the plate, most of which is finished by stamping. Car body, chassis, fuel tank, radiator, boiler drum, container shell, motor, electrical iron core silicon steel sheet are stamping processing. Instrumentation, household appliances, bicycles, office machinery, life utensils and other products, there are a large number of stamping parts.
Customized stamping parts are mainly classified according to process, can be divided into two major categories of separation process and forming process. The separation process, also known as punching, is intended to separate the stamping part from the sheet along a certain contour line while ensuring the quality requirements of the separation section. The surface and intrinsic properties of the stamping sheet have great influence on the quality of the finished product. The thickness of the stamping material is accurate and uniform. The surface is smooth, no spots, no scars, no abrasions, no surface cracks, etc .; the yield strength is uniform and no obvious Directional; uniform elongation; yield ratio is low; low work hardening.
Customized stamping parts are produced under the premise of little material consumption, the parts are light weight, good rigidity, and the sheet after plastic deformation, the internal structure of the metal is improved, so that the strength of the stamping parts increased. Stamping parts with high dimensional accuracy, uniform size with the same module, a better interchangeability. No further machining is required to meet general assembly and use requirements. Stamping parts in the stamping process, because the surface of the material is not damaged, it has a good surface quality, the appearance of smooth and beautiful, which for the surface painting, plating, phosphating and other surface treatment provides a convenient condition.
