Processing technology of stamping parts
Processing technology of stamping parts:
If stamping is classified according to the process, it can be divided into two major processes: forming and separating processes. The index of the forming process is to make the sheet metal plastically deform without breaking the billet to make a workpiece of the required shape and size. The separation process is also called punching, and its purpose is to separate the stamping parts from the sheet along the pre-set outline line, while ensuring the quality requirements of the separated section. In actual production, multiple processes are often integrated and operated on one workpiece. Blanking, straightening, shearing, spinning, and replacement are stamping processes that are often used.
Stamping parts are mainly made of metal or non-metallic sheets by means of press pressure and stamping die. It mainly has the following characteristics: The surface and extension of the sheet metal used for stamping metal stamping parts are subject to stamping waste products. The quality of the stamping material has a great influence, and the thickness of the stamping material is rough and uniform; the surface is bright, no spots, no scars, no scratches, no surface cracks, etc.; uniform obedience strength, no appreciative bias; high uniform stretch rate; low yield ratio ; Low work hardening; stamping parts have high dimensional accuracy, the same size as the mold parts, and good interchangeability. No further machining is required to meet the general assembly and use requirements; the stamping parts are made by pressing on the premise that the material is not consumed, the parts are light in weight, the rigidity is good, and the sheet material is plastically deformed , The internal layout structure of the metal is lost and improved, so that the strength of the stamping parts has been improved; during the stamping process, the stamping parts have a better inner quality because the inner core of the material is not crushed, and the outer appearance is smooth and beautiful. This is the inner spray paint, Electroplating, phosphating and other inner processing provide arbitrary conditions.
