The sheet metal surface and internal performance of stamping has great influence on the quality of the finished sheet metal stampings product, request stamping material thickness precision, uniform;Smooth surface, no spots, no scar, no scratch, no surface crack, etc.;Yield strength evenly, no obvious directivity;High uniform elongation;Showed low;Low strain hardening.Stamping is efficient production methods, the use of compound die, especially the multi-station progressive die, it can be finished in a pressure on multichannel stamping process, realize the pick-up uncoiling, leveling, cutting to the forming and finishing of automatic production.High production efficiency, good working conditions, low production cost, general can produce hundreds of pieces per minute.
Stamping is mainly classified by technology, can be divided into separation process and forming process two kinds big.Separation process is also called the blanking, and its purpose is to make from the sheet metal stamping parts along the contour line must be separated, and at the same time guarantee the quality requirements of the separation section.Forming process is designed to make sheet metal under the condition of not to break the billet occurred plastic deformation, made into the required shape and size of the workpiece.In the actual production, is often a variety of process integrated applied to an artifact.Cutting, bending, shear, deep drawing, bulging, spinning, correction is several main stamping process.
