Applications of a Binder Wrap Calculation Model to Layout of Sheet Steel Forming Dies
This paper presents applications of a binder wrap calculation model to several experimental sheet steel forming dies. In one application of a doubly curved die, the calculated binder wrap agrees with physical tests and calculations reported elsewhere. In another door inner panel die, the designer's intent of having more material in certain part of the die cavity was verified. In the third case, the calculated binder wrap agrees quantitatively with measured data for a decklid stretch-draw die. The later result was used in guiding the modifications of the layout.
