Abstract

Die vorliegend Erfindung betrifft ein Verfahren und eine Platine zur Herstellung von kaltumgeformten Bauteilen (R) aus Stahlblech und eine Verwendung einer Platine umfassend folgende Schritte: Erzeugen einer Platine (P) aus einem Grundblech (G), das aus einem ersten Stahlmaterial besteht; Ersetzen mindestens eines Abschnitts des Grundblechs (G) durch einen Blechzuschnitt (1,2), welcher sich in seiner Dicke (D1,D2) und / oder mindestens einer Materialeigenschaft von dem ersten Stahlblech (G) unterscheidet, wobei die Dicke (D1,D2) oder die abweichende Materialeigenschaft und die Geometrie des Blechzuschnitts (1,2) sowie dessen Lage in der Platine (P) bestimmt sind vom Materialfluß während der anschließend durchgeführten Kaltumformung und Kaltumformen der Platine (P) zu dem Bauteil (R). Das erfindungsgemäße Verfahren ermöglicht es, ein verbessertes Ergebnis der Kaltumformung zu gewährleisten bzw. die Herstellung bestimmter Bauteilformen überhaupt erst möglich zu machen.

The present invention relates to a method and a circuit board for producing cold formed components (R) from sheet steel and the use of a circuit board comprising the following steps: producing a circuit board (P) from a base plate (G) which consists of a first steel material; Replacing at least a section of the base plate (G) with a sheet metal blank (1, 2) which differs in thickness (D1, D2) and / or at least one material property from the first steel plate (G), the thickness (D1, D2 ) or the deviating material properties and the geometry of the sheet metal blank (1, 2) and its position in the board (P) are determined by the material flow during the subsequent cold working and cold working of the board (P) to the component (R). The method according to the invention makes it possible to ensure an improved result of cold forming or to make the production of certain component shapes possible in the first place.
