Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung eines komplexen und im Wesentlichen nach der Formgebung einbaufertigen Blechformteils (30) aus einem Blechmaterial, umfassend die folgenden Schritte:
- Zuschneiden einer ebenen Ausgangsplatine (10), deren Kontur im Wesentlichen einer exakten Abwicklung des einbaufertigen Blechformteils (30) in der Ebene entspricht;
- Positionieren der Ausgangsplatine (10) in einem Umformwerkzeug (20), das wenigstens zwei axial zueinander bewegbare Werkzeugteile (22,25) umfasst; und
- axiales Bewegen dieser Werkzeugteile (22,25) zueinander, wobei ein Umformen der Ausgangsplatine (10) zu einem einbaufertigen Blechformteil (30) derart erfolgt, dass wenigstens zwei Regelflächen und/oder Freiformflächen (32) ausgebildet werden, welche durch wenigstens eine Konturlinie (34) zumindest abschnittsweise voneinander abgegrenzt sind.

Die Erfindung betrifft ferner ein hiernach hergestelltes komplexes Blechformteil (30).

The invention relates to a method for producing a complex sheet-metal molded part (30), which is essentially ready for shaping, from a sheet-metal material, comprising the following steps:
- Cutting a flat output board (10) whose contour substantially corresponds to an exact development of the ready-to-install sheet metal shaped part (30) in the plane;
- Positioning the output board (10) in a forming tool (20) comprising at least two axially movable tool parts (22,25); and
axial movement of these tool parts (22, 25) relative to each other, with reshaping of the output plate (10) to a ready-to-install sheet metal part (30) such that at least two ruled surfaces and / or free-form surfaces (32) are formed, which are defined by at least one contour line ( 34) are at least partially separated from each other.

The invention further relates to a complex sheet metal part (30) produced hereafter.
