摘要： The stamping of a metal sheet within a stamping die is simulated. The die includes a drawbead running perpendicular to a draw direction. A plurality of successive states are generated for iteratively representing the metal sheet from a blank shape to a final stamped shape. The drawbead is represented as a two-dimensional flat band within a model of the stamping die. Forces acting on the metal sheet are calculated at each successive state to define a next successive state. The calculating step includes a restraining force of the drawbead acting on the metal sheet calculated in response to a predetermined function of a length of the metal sheet engaged in the flat band in respective states. The particular width and location of the flat band achieve improved accuracy of estimating the restraining force.

摘要： A method for determining compensated addendum and binder surfaces as part of a springback compensated stamping die for producing a stamped part includes modeling of the existing addendum surface and binder surface of the stamping die. The addendum and binder surfaces are modified according to a number of compensatory surface displacements and in-plane rotations required for springback compensation of the finished stamped part. Following this modification, the stamped part may be separated from the addendum and binder without a loss of dimensional accuracy.

摘要： A method for modifying a stamping die to compensate for springback includes the steps of stamping a first part using a base, or pre-existing die set, and creating a surrogate die having the shape of the first stamped part. These steps are followed by simulated stamping of a blank with the surrogate die, where the blank is shaped according to the desired finished part. Then, the base die is modified by mapping the forming stresses, from the stamped blank, to an indicator blank, which is allowed to relax and then is employed as a template for modification of the base die. Following this, the accuracy of the newly modified base die is determined by stamping a second part in the modified base die and by comparing a number of dimensions of the second part with a number of corresponding dimensions of the desired finished part.
