Stamping process for mainly according to classification, 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.
Compared with the castings, forgings, pressing with a thin, uniform, the characteristics of light and strong.
Stamping can make other methods are difficult to manufacture with rib stiffener, flanging, ups and downs, or artifacts, in order to improve its stiffness.
Because use precision mould, workpiece precision can reach micron grade, and repeat precision is high, the specification is consistent, can punch a hole nest, convex sets, etc.
Metal stamping parts generally no longer by machining, or only need a small amount of machining.
Hot stamping precision and surface state is lower than the cold stamping parts, but it's still better than the castings, forgings, cutting processing capacity.
Reduce metal stamping parts production preparation work and shorten the preparation time, can make the suitable for mass production of advanced punching technology reasonably applied to small batch more varieties of production.
