ABSTRACT:
An apparatus for the simulative optimalization of the supporting of a sheet metal blank on the support frame of a deep-drawing tool includes a plurality of stands that are freely translatable and rotatable about a vertical axis on a horizontally aligned base plate. The stands are capable of being fixed on the base plate in any desired position in respect of translation and rotation. Each stand carries a mouth-like clamp which by means of appropriate lockable mountings can be turned and fastened about two horizontal pivot axes at right angels to one another, and which by means of a fastenable vertical guide can be adjusted and fastened in this vertical position on the stand. Each clamp contains on its bottom face a support part-surface by means of which a partial region of a support surface for the sheet blank can be simulated, and on its top face contains a clamp jaw translatable transversely thereto. With a sheet holder simulation apparatus of this kind the support frame for the sheet blank in a deep-drawing tool can be rapidly and inexpensively optimized.
