introduction：There are many stamping process methods used in the production time，There are many forms of hungry names，But the plastic deformation is essentially the same。Stamping has the following very prominent characteristics。 （1）．Pressure per unit area perpendicular to the direction of the plate surface，Its value does not poop enough to make in the direction of the board The sheet is plastic deformed。Because the quality of the pressure on the unit area perpendicular to the direction of the plate is much less than the internal stress on the direction of the plate，Therefore, most stamping deformation can be treated approximately as a plane stress state，The analysis of deformation mechanics and the calculation of process parameters are made with great sense
