Erfindungsgemäß wir diese Aufgabe durch ein rollprofiliertes Bauteil mit den Merkmalen des Anspruchs 1 gelöst. Das rollprofilierte Bauteil, bei dem es sich insbesondere um ein Strukturteil oder Karosserieteil eines Kraftfahrzeugs handelt, ist aus zwei Einzelteilen hergestellt, die eine über ihre Längsachse veränderliche Höhe aufweisen und die miteinander verbunden sind. Es ist möglich, das Bauteil aus mehr als zwei Einzelteilen herzustellen. Die Verbindung der Einzelteile kann durch Schweißen, insbesondere durch Laserschweißen, erfolgen.According to the invention, we have achieved this object by a roll-profiled component having the features of claim 1. The roll-profiled component, which is in particular a structural part or body part of a motor vehicle, is made of two individual parts, which have a variable height over their longitudinal axis and which are interconnected.

Vorteilhafte Weiterbildungen sind in den Unteransprüchen beschrieben.Advantageous developments are described in the subclaims.

Vorteilhaft ist es, wenn eines oder beide Einzelteile an ihrer Innenkante beschnitten sind. In diesem Fall sind die Einzelteile an den gegebenenfalls beschnittenen Innenkanten miteinander verbunden.It is advantageous if one or both items are cropped at its inner edge. In this case, the items are connected to each other at the optionally trimmed inner edges.

Eine weitere vorteilhafte Weiterbildung ist dadurch gekennzeichnet, daß die Einzelteile einen horizontalen Abschnitt und einen vertikalen Abschnitt aufweisen. Es ist möglich, daß die Einzelteile mehrere horizontale Abschnitte aufweisen. Stattdessen oder zusätzlich können die Einzelteile mehrere vertikale Abschnitte aufweisen. Unter einem horizontalen Abschnitt ist ein Abschnitt zu verstehen, der sich in Richtung der Breite des Einzelteils bzw. Bauteils erstreckt. Unter einem vertikalen Abschnitt ist ein Abschnitt zu verstehen, der sich in der Richtung der Höhe des Einzelteils bzw. des Bauteils erstreckt. Vorteilhaft ist es, wenn das Einzelteil ein Z-Profil mit einem vertikalen und zwei horizontalen Abschnitten aufweist. Es kann ferner vorteilhaft sein, daß das Einzelteil ein L-Profil mit einem horizontalen und einem vertikalen Abschnitt aufweist. Auch andere Profilformen sind möglich.A further advantageous embodiment is characterized in that the items have a horizontal portion and a vertical portion. It is possible that the items have several horizontal sections. Instead or in addition, the items may have multiple vertical sections. A horizontal section is understood to mean a section which extends in the direction of the width of the component or part. A vertical section is understood to mean a section that extends in the direction of the height of the item or of the component. It is advantageous if the item has a Z-profile with a vertical and two horizontal sections. It may also be advantageous that the item has an L-profile with a horizontal and a vertical portion. Other profile shapes are possible.

Eine weitere vorteilhafte Weiterbildung ist dadurch gekennzeichnet, daß die Höhe der Einzelteile bzw. der vertikalen Abschnitte der Einzelteile in der Mitte größer ist als an den Enden. Dies ist insbesondere dann von Vorteil, wenn das Bauteil auf Biegung beansprucht wird. Vorzugsweise weist das Bauteil bzw. Einzelteil in der Mitte die größte Höhe auf.A further advantageous development is characterized in that the height of the individual parts or the vertical portions of the items in the middle is greater than at the ends.

In bestimmten Fällen ist es vorteilhaft, wenn die Einzelteile eine über ihre Längsachse veränderliche Breite aufweisen.In certain cases, it is advantageous if the individual parts have a variable width along their longitudinal axis.

Die der Erfindung zugrundeliegende Aufgabe wird ferner durch ein Verfahren mit den Merkmalen des Anspruchs 6 gelöst. Das Verfahren zur Herstellung eines Bauteils mittels Rollprofilieren, insbesondere eines erfindungsgemäßen Bauteils, ist dadurch gekennzeichnet, daß zwei Einzelteile mit einer über ihre Längsachse veränderlichen Höhe hergestellt werden. Es können auch mehr als zwei Einzelteile hergestellt werden. Die Einzelteile werden durch Rollprofilieren hergestellt.The problem underlying the invention is further achieved by a method having the features of claim 6. The method for producing a component by roll profiling, in particular a component according to the invention, is characterized in that two individual parts with a variable over its longitudinal axis Height can be produced. It can also be made more than two items. The items are manufactured by roll profiling.

Eines oder beide oder alle Einzelteile werden an ihrer Innenkante beschnitten. Dadurch, daß die Einzelteile eine über ihre Längsachse veränderliche Höhe aufweisen, ergeben sich im Allgemeinen nicht geradlinig verlaufende Innenkanten. Die Innenkanten werden vorzugsweise geradlinig beschnitten. Es ist allerdings auch möglich, die Innenkanten nicht geradlinig zu beschneiden.One or both or all parts are trimmed at their inner edge. The fact that the items have a variable height along its longitudinal axis, resulting in generally not rectilinear inner edges. The inner edges are preferably trimmed in a straight line. However, it is also possible not to cut the inner edges straight.

Die Einzelteile werden miteinander verbunden. Vorzugsweise werden die Einzelteile längs der beschnittenen Innenkanten miteinander verbunden. Die Verbindung erfolgt vorzugsweise durch Schweißen, insbesondere durch Laserschweißen.The individual parts are connected to each other.

In Fig. 1 sind ein erstes Einzelteil 1 und ein zweites Einzelteil 2 dargestellt, die beide durch Rollprofilieren aus einem rechteckigen, ebenen Blechstreifen hergestellt worden sind. Das erste Einzelteil 1 weist einen Z-förmigen Querschnitt auf, der aus einem unteren horizontalen Abschnitt 3, einem vertikalen Abschnitt 4 und einem oberen horizontalen Abschnitt 5 besteht. Der untere horizontale Abschnitt 3 weist über die Längsachse des ersten Einzelteils 1 dieselbe Breite auf. Der vertikale Abschnitt 4 weist eine über die Längsachse des ersten Einzelteils 1 veränderliche Höhe auf. Die Höhe des vertikalen Abschnitts 4 ist an den Enden des ersten Einzelteils 1 am geringsten. Sie steigt zur Mitte hin an und erreicht in der Mitte die größte Höhe. Die Höhe des vertikalen Abschnitts 4 folgt einem im wesentlichen S-förmigen Verlauf. Sie ist in der Mitte größer als an den Enden.In Fig. 1 a first item 1 and a second item 2 are shown, both of which have been made by roll profiling from a rectangular, flat sheet metal strip. The first item 1 has a Z-shaped cross-section, the a lower horizontal portion 3, a vertical portion 4 and an upper horizontal portion 5 consists. The lower horizontal section 3 has the same width over the longitudinal axis of the first item 1. The vertical section 4 has a variable height over the longitudinal axis of the first item 1. The height of the vertical portion 4 is lowest at the ends of the first item 1. It climbs towards the middle and reaches the highest altitude in the middle. The height of the vertical section 4 follows a substantially S-shaped course. It is larger in the middle than at the ends.

Diese Ausgestaltung ist insbesondere dann von Vorteil, wenn das Bauteil auf Biegung beansprucht wird, da das Biegemoment in der Mitte des Bauteils am größten ist und dort die größere Höhe der vertikalen Abschnitte dem Biegemoment den größten Widerstand entgegensetzt.This embodiment is particularly advantageous when the component is subjected to bending, since the bending moment in the middle of the component is greatest and there the greater height of the vertical portions of the bending moment opposes the greatest resistance.

Da die Höhe des vertikalen Abschnitts 4 des ersten Einzelteils 1 über die Längsachse des Bauteils veränderlich ist, bildet die Innenkante 6 am Ende des oberen horizontalen Abschnitts 5 keine gerade Linie. Im Ausführungsbeispiel wird in der Mitte des ersten Einzelteils 1 mehr Material für den vertikalen Abschnitt 4 benötigt, so daß dort für den oberen horizontalen Abschnitt 5 weniger Material zur Verfügung steht. Die Breite des oberen horizontalen Abschnitts 5 ist also in der Mitte des ersten Einzelteils 1 geringer als an den Enden.Since the height of the vertical portion 4 of the first item 1 is variable over the longitudinal axis of the component, the inner edge 6 at the end of the upper horizontal portion 5 does not form a straight line. In the embodiment, more material for the vertical portion 4 is required in the middle of the first item 1, so that there is less material available for the upper horizontal section 5. The width of the upper horizontal portion 5 is thus lower in the middle of the first item 1 than at the ends.

Das zweite Einzelteil 2 ist zum ersten Einzelteil 1 symmetrisch und umfaßt die entsprechenden Bestandteile 3', 4', 5' und 6'. Die Ausführungen zum ersten Einzelteil 1 gelten in entsprechender Weise für das zweite Einzelteil 2.The second item 2 is symmetrical to the first item 1 and includes the corresponding components 3 ', 4', 5 'and 6'. The comments on the first item 1 apply in a corresponding manner for the second item. 2

Die Einzelteile 1, 2 werden an ihren Innenkanten 6, 6' beschnitten. Wie aus Fig. 2 ersichtlich werden die Einzelteile 1, 2 an ihren Innenkanten 6, 6' geradlinig beschnitten, so daß geradlinige, parallel zur Längsachse der Einzelteile 1, 2 verlaufenden Schnittkanten 7, 7' gebildet werden.The items 1, 2 are trimmed at their inner edges 6, 6 '. How out Fig. 2 it can be seen the items 1, 2 'at their inner edges 6, 6' rectilinear, so that rectilinear, parallel to the longitudinal axis of the items 1, 2 extending cutting edges 7, 7 'are formed.

Anschließend werden die Einzelteile 1, 2 längs der Schnittkanten 7, 7' miteinander verbunden, nämlich verschweißt, insbesondere laserverschweißt. Hierdurch wird das in Fig. 3 gezeigte Bauteil 8 gebildet, das eine über seine Längsachse veränderliche Höhe aufweist. Das Bauteil 8 hat über seine Längsachse überall dieselbe Breite, also überall denselben Abstand der vertikalen Abschnitte 4, 4'. Es könnte allerdings auch eine über seine Längsachse veränderliche Breite aufweisen (in der Zeichnung nicht dargestellt).Subsequently, the items 1, 2 along the cutting edges 7, 7 'connected to each other, namely welded, in particular laser welded. As a result, the in Fig. 3 shown component 8 is formed, which has a height variable over its longitudinal axis. The component 8 has over its longitudinal axis everywhere the same width, ie everywhere the same distance between the vertical sections 4, 4 '. However, it could also have a variable width along its longitudinal axis (not shown in the drawing).

Die Querschnitte des Bauteils 8 bilden, wie aus Fig. 4 ersichtlich, ein Hutprofil mit unteren horizontalen Abschnitten 3, 3', vertikalen Abschnitten 4, 4' und oberen horizontalen Abschnitten 5, 5', die längs der inneren Schnittkanten 7, 7' miteinander verschweißt sind. Am Ende des Bauteils 8, also im Schnitt A-A, ist dessen Höhe geringer als in der Mitte, nämlich im Schnitt B-B.The cross sections of the component 8 form as shown Fig. 4 can be seen, a hat profile with lower horizontal sections 3, 3 ', vertical sections 4, 4' and upper horizontal sections 5, 5 ', which along the inner cutting edges 7, 7' are welded together. At the end of the component 8, so in section AA, whose height is less than in the middle, namely in section BB.

Durch die Erfindung wird eine Variation des Querschnitts bei einem rollprofilierten Bauteil ermöglichst, und zwar durch die Ausbildung zweier oder mehrerer Einzelteile bzw. Segmente, die in der Längsachse einen variablen Querschnitt aufweisen. Die Einzelteile 1, 2 können auf einer Anlage rollprofiliert werden. Die Einzelteile 1, 2 werden anschließend beschnitten. Sie können zu einem diskontinuierlich lasergefügten Bauteil zusammengefügt werden. Durch die Erfindung können alle Vorteile erreicht werden, die das Verfahren des Rollformens gegenüber dem Verfahren des Pressens mit sich bringen, insbesondere niedrige Werkzeugkosten, hohe Restplastifizität und Toleranzen. Der Beschnitt der Innenkanten 6, 6' kann online erfolgen.The invention makes it possible to vary the cross section in a roll-profiled component, specifically by forming two or more individual parts or segments which have a variable cross-section in the longitudinal axis. The items 1, 2 can be rollprofiled on a system. The items 1, 2 are then trimmed. They can be joined together to form a discontinuously laser-bonded component. By the invention all advantages can be achieved, which entail the method of roll forming compared to the method of pressing, in particular low tooling costs, high residual plasticity and tolerances. The trimming of the inner edges 6, 6 'can be done online.

Das Bauteil kann mit folgenden Verfahrensschritten hergestellt werden: (1) Konventionelles Walzen; (2) Variation beider Einzelteile bzw. Segmente, insbesondere in der Höhe; (3) Beschnitt online; (4) fügen und schweißen, insbesondere Laserschweißen; (5) Abschneiden der Enden.The component can be manufactured by the following process steps: (1) Conventional rolling; (2) variation of both individual parts or segments, in particular in height; (3) trimming online; (4) join and weld, in particular laser welding; (5) cutting off the ends.

Die Einzelteile können als zwei Rollprofile in einem Gerüst hergestellt werden.The individual parts can be produced as two rolling profiles in a scaffold.
