  • Patent number: 11292221
    Abstract: A press and a process for operating it, has an upper tool and a lower tool for shaping a workpiece and a work unit including a press drive and/or a drawing device, is controllable by a controller, to perform the shaping process. The controller outputs, to the work unit, press process values, which define the sequence of events of the shaping process. Workpiece parameters characterize, for example, the material and/or the shape and/or at least one dimension and/or quality of the workpiece, which still has to be shaped or has already been shaped. The controller is assigned a composition matrix which contains, for each defined workpiece parameter and for each defined press process value, an individually changeable function, to describe the relationship between every one of the defined workpiece parameters and the defined press process values. This composition matrix allows a quick and rapid adjustment and adaptation of the press.

  • Patent number: 11285523
    Abstract: A metal blank is clamped between upper and lower binders with the metal blank engaging against a protrusion extending from a binder surface of any of the upper binder, the lower binder, and both upper and lower binders, to create a binder gap between the metal blank and the binder surface adjacent the protrusion. The binder gap prevents cooperating springback control binder elements of the binder surface from actively engaging the metal blank. The metal blank is drawn into a cavity, with the protrusion riding on the metal blank until the protrusion falls off an edge of the metal blank, which closes the binder gap between the metal blank and the binder surface causing the cooperating springback control binder elements to actively engage the blank for the post-forming stretching operation.
