Metal stamping is a very wide range of industry field; it is deep into all aspect of the manufacturing sector. Metal stamping is a kind of processing which use punch and die to make iron, aluminum, copper plates and heterosexual material to deform or rupture, then get a certain shape and size.
Metal stamping process can be divided into two categories: separate processes and forming process. Forming process is designed to make sheet metal occurred plastic deformation without any breaking, then to be the work piece as specificitied. Separation process is also called the blanking, its purpose is to make stamping parts separated from the sheet metal along a certain contour line, and at the same time guarantee the quality of the separation section. In the actual production, one work piece is made by many kinds of process. Main stamping processes are: cutting, bending, trimming, deep drawing, bulging, spinning, adjusting.
Stamping product’s quality are highly affected by sheet metal stamping material’s surface and internal performance, like: 1.accurate thickness, 2.surface without spots, scars, bruises and cracks; 3.uniform yield strength, no obvious directionality; 4.uniform elongation; low strain hardening.
Metal stamping equipment except heavy plate used Hydraulic press forming, generally used mechanical press. In modern high-speed transfer mechanical press as the center, equipped with uncoiling, leveling, finished products collection, transportation and other machinery, as well as mold libraries and quick die change device, using a computer program control the whole process, in this way we can form high productivity automatic stamping production line.
