Stamping die are tools used to produce high volume sheet metal parts. These parts achieve their shape through the effects of the stamping die tooling. It is a special, one-of -a- kind precision tool that cuts and forms sheet metal into a desired shape or profile. A special type of hardenable steel called tool steel is used to make the die's cutting and forming sections. Carbide and various other hard, wear-resistant materials are also used to make die's cutting and forming sections. Several Stamping mould basic components, including die plates, shoes, die sets, guide pins, bushings, heel blocks, heel plates, screws, dowels and keys are used to construct stamping die. Dies also need stripper, pressure, Stamping mould and drawing pads, as well as the devices used to secure them: spools, shoulder bolts, keepers and retainers, as well as gas, coil, or urethane springs.
Formability-(the primary attribute of sheet metal material), is defined as the materials ability to be bent, stretched and drawn. The metallurgical term for these qualities is 'ductility'. Ductility is the materials ability to deform and elongate without fracture. The extent to which a stamping die is subjected to such deformation is directly related to the part's overall shape and geometry. The die design, the press, press speed, lubrication are some of the factors that influence the material's formability.
The word 'die' is a generic term used to describe the tooling used to produce stamped parts in Stamping mould. A die set assembly consisting of a male and female component is the actual tool that produces the shaped stamping die. The male and female components work in opposition to both form and punch holes in the stock. The upper half of the stamping die set, which may be either the male or female, is mounted on the press ram and delivers the stroke action. The lower half is attached to an intermediate bolster plate which in turn is secured to the press bed. Guide pins are used to ensure alignment between the upper and lower halves of the die set.
