Definitions
- the invention relates to a method for producing components, in particular of components for motor vehicles.
- the components are produced by roll profiling from a starting material having a longitudinal extent.
- the roll-profiled component is in particular a structural part or body part of a motor vehicle.
- a method for producing a metal profiled bar in which the profiled bar is formed from a strip metal by means of a roll forming device having rollers.
- the strip material is trimmed to produce a cross section over its longitudinal variable profile bar before roll forming at the longitudinal edge edges according to the desired change in cross section of the profile bar over its length.
- the trimming takes place only at predetermined locations. It takes place in such a way that at these points a different cross section results for the rest of the longitudinal course.
- the EP 1 955 788 B1 discloses a method for producing a component, in particular for a motor vehicle, by means of roll profiling, in which two individual parts are produced by roll profiling with a variable height over their longitudinal axis and then joined together, in particular by welding or laser welding. After roll profiling, one or both pieces are trimmed at their inner edges. The individual parts are connected to each other at their inner edges.
- the object of the invention is to propose an improved method of the type specified.
- this object is solved by the features of claim 1.
- a pre-cut is made in the scrap area of the starting material, which lies between the adjacent areas for two components.
- the pre-cut is introduced in a direction transverse to the longitudinal extent of the starting material. He acts as a relief cut.
- the subsequent roll profiling introduces stresses into the starting material. These stresses can be reduced by pre-cutting.
- the pre-trimming is V-shaped.
- the tip of the V is preferably rounded.
- the radius of the tip of the V is preferably 0.5 to 5 mm, more preferably 1 to 3 mm, further preferably 1.5 to 2 mm.
- a pre-cut is introduced on both sides of the starting material.
- the pre-cut can be made the same or different on both sides.
- the starting material is trimmed over its length prior to roll profiling.
- a longitudinal contour of the starting material is produced, which continues accordingly in the finished component.
- the component can be cut off after roll profiling. This is preferably done so that the pre-cut is completely removed.
- the component has a U-profile or a hat profile with a base surface and side surfaces.
- the base surface extends in the longitudinal extent of the starting material and thus also of the component. It is located in the middle of the starting material and thus also of the component.
- the side surfaces adjoin the base surface on both sides.
- the component is a sill reinforcement of a motor vehicle.
- the pre-cut is introduced in the region of the starting material which is roll-formed into a side surface of the component. It may be advantageous if the pre-cut is introduced only on one side of the starting material. Preferably, the pre-cut is introduced on the side of the starting material that is roll formed into the side face with the greater deformation. There arise the larger voltages, so that it is advantageous to provide the pre-cutting on this page.
- a further advantageous development is characterized in that the pre-cut ends at a distance from the region of the starting material which is roll-formed to the base surface of the component.
- the pre-cut is V-shaped, its tip preferably terminates at a distance from the region of the starting material that is roll formed to the base surface of the component.
- the pre-cut or tip of the pre-cut preferably terminates a short distance from the region of the starting material that is roll formed to the base surface of the component.
- the distance is preferably 0.5 to 5 mm, more preferably 1 to 3 mm, further preferably 1.5 to 2 mm.
- the method may therefore be a strip metal (also called “coil”) as the starting material. use.
- a strip metal also called “coil”
- the scrap area between two adjacent components, which runs transversely to the longitudinal extent of the components, then preferably forms the axis of symmetry of the adjacent components. If a coil is used as the starting material, it is advantageous if each scrap region forms an axis of symmetry of the respectively adjacent components.
- Fig. 1 shows a board of a suitable metal, which serves as a starting material 1 for the production of two sill boosters for a motor vehicle. From the left half 2 of the starting material 1, a right sill enhancer is made, from the right half 3 of the starting material 1, a left sill enhancer is produced.
- the scrap area 4 lying between the halves 2, 3 extends transversely to the longitudinal extent 5 of the starting material 1. It forms an axis of symmetry for the halves 2, 3.
- sill enhancers were to be made from one coil, then another scrap region would join the left end edge 6 and the starting material for a further left sill reinforcement, the further scrap region being an axis of symmetry between the left half 2 and the further source material for the further left sill reinforcement would form. This sequence of starting material for right and left sill reinforcements would then continue correspondingly along the coil.
- the starting material 1 is trimmed over its length. It therefore has in its longitudinal extent 5 a variable longitudinal contour.
- the left half 2 and the right half 3 of the starting material 1 each form an area for two adjacent components, namely sill reinforcements. How out Fig. 2 it can be seen in the scrap area 4, a pre-cut 7 is introduced.
- the pre-cut 7 is introduced in a direction transverse to the longitudinal extent 5 of the starting material 1. He is V-shaped.
- the pre-cut has a left cutting edge 8 and a right cutting edge 9.
- the tip 10 of the precut 7 is rounded.
- the angle of the cut edges 8, 9 to the transverse direction of the starting material 1 is 5 ° in each case. It is advantageous if this angle is greater than 0 ° and less than 10 °. In particular, angle ranges between 1 ° and 8 ° are advantageous, further angles between 3 ° and 6 °.
- the radius of the tip 10 is 1.5 mm.
- the starting material 1 is roll profiled. This creates the in 3 and 4 shown, finished rollprofiled double part in which the pre-cut 7 is still present.
- the roll profiled double part consists of a right sill reinforcement 11, a left sill reinforcement 12 and the scrap area 4 located therebetween.
- the sill reinforcements 11, 12 have a hat profile.
- the hat profile comprises a base surface 13 and side surfaces 14, 15, 16, 17.
- the side surfaces 14, 15 lie on the side of the precut 7 of the base surface 13, the side surfaces 16, 17 lie on the opposite side of the base surface 13.
- the side surfaces 14, 16 close to the base surface 13 at. They extend at a substantially right angle to the base surface 13.
- the side surfaces 15, 17 close to the ends of the side surfaces 14, 16 at. They extend substantially parallel to the base surface 13, in each case from the base surface 13 away to the outside.
- the preliminary cut 7 is introduced into the region of the starting material 1 which is roll-formed into a side face 14, 15 of the component, namely the sill reinforcement 12, 13.
- the pre-cut 7, namely the tip 10 of the precut 7 ends at a distance from the region of the starting material 1, which is roll-formed to the base surface 13 of the component.
- the distance of the tip 10 from the base surface 13 is 1.5 mm.
- the components namely the sill reinforcements 12, 13, cut off.
- the left sill reinforcement 13 is cut along the right edge 18 of the scrap area 4.
- the right sill enhancer 12 is cut along the left edge 19 of the scrap area 4.
- the pre-cut 7 is completely within the scrap area 4. The cut edges 8, 9 of the pre-cut 7 are thus spaced from the edges 18, 19.
- a roll forming is said to be variable if the cross section of the component is variable, that is, if the width of the starting material is variable.
- the pre-cut acts as a relief cut, which reduces or prevents tensions during further forming by roll profiling.
- a pre-cut in the respective scrap area (transition area) of a double part or adjacent parts on a coil can be cut with a punching tool.
- the pre-cut can be carried out as a shaped cut, for example in a V-shape or in another suitable form.
- the board or the belt (coil) passes through the following profile rollers until the finished gear.
- the double part or a series of parts on a coil are continuously roll profiled.
- the preparation of the outer contour can be done by a press, in a production of a coil, the preparation of the outer contour can be done by cutting rollers.
- the pre-cutting can be carried out synchronously with the outer trimming. However, it is also possible to perform the preliminary trimming before or after the outer trimming.

Die
Aufgabe der Erfindung ist es, ein verbessertes Verfahren der eingangs angegebenen Art vorzuschlagen.The object of the invention is to propose an improved method of the type specified.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruchs 1 gelöst. Vor dem Rollprofilieren wird in den Schrottbereich des Ausgangsmaterials, der zwischen den benachbarten Bereichen für zwei Bauteile liegt, ein Vorbeschnitt eingebracht. Der Vorbeschnitt wird in einer Richtung quer zur Längserstreckung des Ausgangsmaterials eingebracht. Er wirkt als Entlastungsschnitt. Durch das anschließende Rollprofilieren werden Spannungen in das Ausgangsmaterial eingebracht. Diese Spannungen können durch den Vorbeschnitt reduziert werden.According to the invention, this object is solved by the features of
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.Advantageous developments of the invention are described in the subclaims.
Vorteilhaft ist es, wenn der Vorbeschnitt V-förmig ist. Die Spitze des V ist vorzugsweise abgerundet. Der Radius der Spitze des V beträgt vorzugsweise 0,5 bis 5 mm, ferner vorzugsweise 1 bis 3 mm, ferner vorzugsweise 1,5 bis 2 mm.It is advantageous if the pre-trimming is V-shaped. The tip of the V is preferably rounded. The radius of the tip of the V is preferably 0.5 to 5 mm, more preferably 1 to 3 mm, further preferably 1.5 to 2 mm.
In bestimmten Fällen kann es vorteilhaft sein, wenn auf beiden Seiten des Ausgangsmaterials ein Vorbeschnitt eingebracht wird. Der Vorbeschnitt kann auf beiden Seiten gleich oder verschieden ausgebildet werden.In certain cases, it may be advantageous if a pre-cut is introduced on both sides of the starting material. The pre-cut can be made the same or different on both sides.
In bestimmten Fällen ist es allerdings vorteilhaft, wenn nur auf einer Seite des Ausgangsmaterials ein Vorbeschnitt eingebracht wird.In certain cases, however, it is advantageous if only on one side of the starting material, a pre-cut is introduced.
Nach einer weiteren vorteilhaften Weiterbildung wird das Ausgangsmaterial vor dem Rollprofilieren über seine Länge beschnitten. Es wird also eine Längskontur des Ausgangsmaterials hergestellt, die sich im fertigen Bauteil entsprechend fortsetzt.According to a further advantageous development, the starting material is trimmed over its length prior to roll profiling. Thus, a longitudinal contour of the starting material is produced, which continues accordingly in the finished component.
Das Bauteil kann nach dem Rollprofilieren abgeschnitten werden. Dies erfolgt vorzugsweise derart, daß der Vorbeschnitt vollständig entfernt wird.The component can be cut off after roll profiling. This is preferably done so that the pre-cut is completely removed.
Eine weitere vorteilhafte Weiterbildung ist dadurch gekennzeichnet, daß das Bauteil ein U-Profil oder ein Hutprofil mit einer Basisfläche und Seitenflächen aufweist. Die Basisfläche erstreckt sich in der Längserstreckung des Ausgangsmaterials und damit auch des Bauteils. Sie befindet sich in der Mitte des Ausgangsmaterials und damit auch des Bauteils. Die Seitenflächen schließen sich beidseitig an die Basisfläche an. Insbesondere handelt es sich bei dem Bauteil um eine Schwellerverstärkung eines Kraftfahrzeugs.A further advantageous development is characterized in that the component has a U-profile or a hat profile with a base surface and side surfaces. The base surface extends in the longitudinal extent of the starting material and thus also of the component. It is located in the middle of the starting material and thus also of the component. The side surfaces adjoin the base surface on both sides. In particular, the component is a sill reinforcement of a motor vehicle.
Nach einer weiteren vorteilhaften Weiterbildung wird der Vorbeschnitt in dem Bereich des Ausgangsmaterials eingebracht, der zu einer Seitenfläche des Bauteils rollgeformt wird. Dabei kann es vorteilhaft sein, wenn der Vorbeschnitt nur auf einer Seite des Ausgangsmaterials eingebracht wird. Vorzugsweise wird der Vorbeschnitt auf derjenigen Seite des Ausgangsmaterials eingebracht, der zu der Seitenfläche mit der größeren Verformung rollgeformt wird. Dort entstehen die größeren Spannungen, so daß es vorteilhaft ist, den Vorbeschnitt auf dieser Seite vorzusehen.According to a further advantageous development, the pre-cut is introduced in the region of the starting material which is roll-formed into a side surface of the component. It may be advantageous if the pre-cut is introduced only on one side of the starting material. Preferably, the pre-cut is introduced on the side of the starting material that is roll formed into the side face with the greater deformation. There arise the larger voltages, so that it is advantageous to provide the pre-cutting on this page.
Es kann allerdings auch vorteilhaft sein, den Vorbeschnitt auf beiden Seiten des Ausgangsmaterials einzubringen.However, it may also be advantageous to introduce the pre-cut on both sides of the starting material.
Eine weitere vorteilhafte Weiterbildung ist dadurch gekennzeichnet, daß der Vorbeschnitt in einem Abstand von dem Bereich des Ausgangsmaterials endet, der zur Basisfläche des Bauteils rollgeformt wird. Wenn der Vorbeschnitt V-förmig ist, endet dessen Spitze vorzugsweise in einem Abstand von dem Bereich des Ausgangsmaterials, der zur Basisfläche des Bauteils rollgeformt wird. Der Vorbeschnitt bzw. die Spitze des Vorbeschnitts endet vorzugsweise in einem geringen Abstand von dem Bereich des Ausgangsmaterials, der zur Basisfläche des Bauteils rollgeformt wird. Der Abstand beträgt vorzugsweise 0,5 bis 5 mm, ferner vorzugsweise 1 bis 3 mm, ferner vorzugsweise 1,5 bis 2 mm.A further advantageous development is characterized in that the pre-cut ends at a distance from the region of the starting material which is roll-formed to the base surface of the component. When the pre-cut is V-shaped, its tip preferably terminates at a distance from the region of the starting material that is roll formed to the base surface of the component. The pre-cut or tip of the pre-cut preferably terminates a short distance from the region of the starting material that is roll formed to the base surface of the component. The distance is preferably 0.5 to 5 mm, more preferably 1 to 3 mm, further preferably 1.5 to 2 mm.
Vorteilhaft ist es, wenn das Verfahren kontinuierlich durchgeführt wird. Das Verfahren kann also als Ausgangsmaterial ein Bandmetall (auch als "Coil" bezeichnet) verwenden. Es ist allerdings auch möglich, als Ausgangsmaterial eine Platine zu verwenden, aus der mehrere, insbesondere zwei Bauteile hergestellt werden. Vorteilhaft ist es, wenn zwei symmetrische Bauteile hergestellt werden. Der Schrottbereich zwischen zwei benachbarten Bauteilen, der quer zur Längserstreckung der Bauteile verläuft, bildet dann vorzugsweise die Symmetrieachse der benachbarten Bauteile. Wenn als Ausgangsmaterial ein Coil verwendet wird, ist es vorteilhaft, wenn jeder Schrottbereich eine Symmetrieachse der jeweils benachbarten Bauteile bildet.It is advantageous if the process is carried out continuously. The method may therefore be a strip metal (also called "coil") as the starting material. use. However, it is also possible to use as starting material a circuit board, from which several, in particular two components are produced. It is advantageous if two symmetrical components are produced. The scrap area between two adjacent components, which runs transversely to the longitudinal extent of the components, then preferably forms the axis of symmetry of the adjacent components. If a coil is used as the starting material, it is advantageous if each scrap region forms an axis of symmetry of the respectively adjacent components.

Wenn die Schwellerverstärker aus einem Coil hergestellt werden würden, würde sich an die linke Endkante 6 ein weiterer Schrottbereich anschließen sowie das Ausgangsmaterial für eine weitere linke Schwellerverstärkung, wobei der weitere Schrottbereich eine Symmetrieachse zwischen der linken Hälfte 2 und dem weiteren Ausgangsmaterial für die weitere linke Schwellerverstärkung bilden würde. Diese Abfolge von Ausgangsmaterial für rechte und linke Schwellerverstärkungen würde sich dann längs des Coils entsprechend fortsetzen.If the sill enhancers were to be made from one coil, then another scrap region would join the left end edge 6 and the starting material for a further left sill reinforcement, the further scrap region being an axis of symmetry between the

Nach dem Rollformen werden die Bauteile, nämlich die Schwellerverstärkungen 12, 13, abgeschnitten. Die linke Schwellerverstärkung 13 wird längs des rechten Randes 18 des Schrottbereichs 4 abgeschnitten. Der rechte Schwellerverstärker 12 wird längs des linken Randes 19 des Schrottbereichs 4 abgeschnitten. Der Vorbeschnitt 7 liegt vollständig innerhalb des Schrottbereichs 4. Die Schnittkanten 8, 9 des Vorbeschnitts 7 sind also von den Rändern 18, 19 beabstandet.After roll forming, the components, namely the
Durch das Einbringen eines bestimmten Vorbeschnitts im Schrottbereich (Übergangsbereich) vom linken Teil zum rechten Teil eines Doppelteils oder von benachbarten Teilen auf einem Coil ist es möglich, ein stark in der Breite variierendes Bauteil, beispielsweise eine Schwellerverstärkung in Form eines Hutprofils, mittels variablem Rollformen herzustellen. Ein Rollformen wird als variabel bezeichnet, wenn der Querschnitt des Bauteils variabel ist, wenn also die Breite des Ausgangsmaterials variabel ist. Das Verfahren kann mit besonderem Vorteil bei symmetrischen Bauteilen angewendet werden, wie sie bei Kraftfahrzeugen (linksrechts) häufig vorkommen.By introducing a certain Vorbeschnitts in the scrap area (transition region) from the left part to the right part of a double part or of adjacent parts on a coil, it is possible to produce a strongly varying in width component, such as a sill reinforcement in the form of a hat profile, by means of variable roll forming , A roll forming is said to be variable if the cross section of the component is variable, that is, if the width of the starting material is variable. The method can be used with particular advantage in symmetrical components, as they often occur in motor vehicles (left-right).
Bisher ist es technisch nicht möglich, ein Bauteil für ein Kraftfahrzeug innerhalb der in der Automobilindustrie üblicherweise geforderten Toleranzen mittels variablem Rollprofilieren herzustellen, wenn das Bauteil eine starke Querschnittsveränderung innerhalb des Bauteils aufweist. Durch die Erfindung wird dies ermöglicht. Der Vorbeschnitt wirkt als Entlastungsschnitt, der Spannungen beim weiteren Umformen durch Rollprofilieren vermindert oder verhindert.So far, it is technically not possible to produce a component for a motor vehicle within the tolerances usually required in the automotive industry by means of variable roll profiling, if the component has a strong cross-sectional change within the component. This is made possible by the invention. The pre-cut acts as a relief cut, which reduces or prevents tensions during further forming by roll profiling.
Vor dem ersten Rollprofiliergang kann mit einem Stanzwerkzeug ein Vorbeschnitt im jeweiligen Schrottbereich (Übergangsbereich) eines Doppelteils oder benachbarter Teile auf einem Coil geschnitten werden. Der Vorbeschnitt kann als Formschnitt ausgeführt werden, beispielsweise in einer V-Form oder in einer anderen geeigneten Form. Danach durchläuft die Platine oder das Band (Coil) die nachfolgenden Profilrollen bis zum Fertiggang. Das Doppelteil oder eine Reihe von Teilen auf einem Coil werden zusammenhängend rollprofiliert. Bei Platinenfertigung kann die Anfertigung der Außenkontur durch eine Presse erfolgen, bei einer Fertigung von einer Coil kann die Anfertigung der Außenkontur durch Schneidrollen erfolgen. Der Vorbeschnitt kann synchron mit dem Außenbeschnitt durchgeführt werden. Es ist allerdings auch möglich, den Vorbeschnitt vor oder nach dem Außenbeschnitt durchzuführen.Before the first roll profiling step, a pre-cut in the respective scrap area (transition area) of a double part or adjacent parts on a coil can be cut with a punching tool. The pre-cut can be carried out as a shaped cut, for example in a V-shape or in another suitable form. Thereafter, the board or the belt (coil) passes through the following profile rollers until the finished gear. The double part or a series of parts on a coil are continuously roll profiled. When board production, the preparation of the outer contour can be done by a press, in a production of a coil, the preparation of the outer contour can be done by cutting rollers. The pre-cutting can be carried out synchronously with the outer trimming. However, it is also possible to perform the preliminary trimming before or after the outer trimming.
