Abstract:
1. A method for designing a tool for deep drawing of sheet metal to form a sheet metal component having a predefined component geometry, said tool comprising a die, a binder and a punch, whereby the binder is used to fix the sheet metal in an edge zone of the die, before the sheet metal is pressed in a drawing direction by the punch into the die, said tool comprising at least one addendum zone surrounding the component, said tool is generated by a method comprising: (a) preparing the predefined component geometry; (b) determining a direction of drawing; (c) creating a fill surface for smoothing irregular zones of an edge of the predefined component geometry; (d) generating a binder surface; (e) generating the at least one addendum zone by (f) interactively adapting characteristic lines and correspondingly adapting the at least one addendum zone; and (g) creating a punch opening line as intersections of the sectional profiles with the binder surface.
