Abstract
Description
Die Erfindung betrifft ein Verfahren und Vorrichtung zum Herstellen von Biegeprofilen nach dem Oberbegriff der unabhängigen Patentansprüche.The invention relates to a method and device for producing Bending profiles according to the preamble of the independent claims.
Aus dem Stand der Technik sind bisher nur getrennte, eigenständige Vorrichtungen und Verfahren einerseits zur Herstellung eines Stangenprofils aus einem Grundmaterial (z.B. Blechmaterial) und andererseits zum Biegen dieses Stangenprofils bekannt.So far, only separate, independent ones are from the prior art Devices and methods on the one hand for producing a bar profile a base material (e.g. sheet metal) and on the other hand for bending it Bar profile known.
Die Herstellung eines Stangenprofils wird dabei bevorzugt durch ein Roll-Profilier-Verfahren bewerkstelligt, zur Herstellung von geschlossenen, teiloffenen oder offenen Profilen unterschiedlichster Querschnittsgestaltung und Wandstärkenauslegung aus Blechband, insbesondere von einem sogenannten "Coil", einer sehr großen Abwickelspule.The production of a bar profile is preferred by a roll profiling process accomplished, for the production of closed, partially open or open profiles of various cross-sectional designs and Wall thickness design from sheet metal strip, in particular from a so-called "Coil", a very large unwinding spool.
Das im Anschluss daran auf einer gesonderten Maschine durchgeführte Biegen des zuvor auf der Roll-Profilier-Maschine hergestellten Stangenprofils wird insbesondere durch das 2- oder 3-dimensionale Profilwalzbiege-Verfahren durchgeführt.Subsequent bending on a separate machine of the bar profile previously produced on the roll profiling machine in particular through the 2 or 3-dimensional roll forming process carried out.
Nachteil dabei ist, dass das Herstellen von Stangenprofilen und anschließende Biegen der Stangenprofile auf getrennten Maschinen sehr zeitaufwendig ist und zudem einer erhöhten Logistik bedarf, da eine Zwischenlagerung und ein Transport zwischen den Maschinen nötig ist. Zudem ist der Materialverlust deshalb nicht unerheblich, da die Norm-Stangenprofile nur in vordefinierten Längen angeboten werden und dann beim Ablängen des fertig gebogenen Stangenprofils nicht selten 10-20 % der Länge als Verschnitt der Enden zwischen den Profilen verloren geht. Damit ist die Herstellung eines 2- oder 3-dimensionalen Biegeprofils sehr kosten- und zeitintensiv. The disadvantage here is that the production of bar profiles and subsequent Bending the bar profiles on separate machines is very time consuming and In addition, increased logistics is required, since temporary storage and a Transport between machines is necessary. In addition, the loss of material therefore not insignificant, since the standard bar profiles only in predefined Lengths are offered and then when cutting the finished bent Bar profile not infrequently 10-20% of the length as a blend of the ends between the profiles is lost. So that is the manufacture of a 2- or 3-dimensional Bending profile very costly and time consuming.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung vorzusehen, das eine Zwischenlagerung und einen Transport zwischen den bisher benötigten zwei Maschinen, d.h. zwischen dem Herstellverfahren der Stangenprofile und dem Biegeverfahren der hergestellten Stangenprofile vermeidet und somit eine kostengünstigere Vorrichtung und ein kostengünstigeres Verfahren zum Herstellen von Stangenprofilen aus Blechmaterial und zum Biegen dieser Stangenprofile in einer einzigen Vorrichtung vorsieht. Zudem soll das eingesetzte Profilmaterial optimal ausgenutzt werden mit möglichst geringen Verlusten.The invention is therefore based on the object, a method and a To provide device, the intermediate storage and transport between the two machines previously required, i.e. between the Manufacturing process of the bar profiles and the bending process of the manufactured Avoids bar profiles and thus a less expensive device and a cost-effective method for producing bar profiles Sheet material and for bending these bar profiles in a single device provides. In addition, the profile material used should be optimally used with losses as low as possible.
Zur Lösung dient die technische Lehre der unabhängigen Patentansprüche.The technical teaching of the independent claims serves to solve this.
Wesentliches Merkmal dabei ist, dass ein Verfahren und eine Vorrichtung verwendet wird, welche das Verfahren zur Herstellung des Stangenprofiles und das Verfahren zum Biegen des hergestellten Stangenprofiles in einer einzigen Roll-Form-Biege-Maschine (RFB) kombiniert.An essential feature is that a method and a device is used, which is the process for producing the bar profile and the process for bending the manufactured bar profile in a single Combined roll-form-bending machine (RFB).
Vorteil dabei ist, dass die im kontinuierlichen Durchlaufverfahren hergestellten Blechprofile ebenso kontinuierlich auf ein und der selben Vorrichtung gebogen werden können und insbesondere über eine "fliegende Abtrennanlage" (Sägen, Schneiden, Scheren etc.) ohne Unterbrechung (und damit ohne wesentlichen Verschnitt) auf Soll-Maß abgelängt werden, so dass die fertig hergestellten und gebogenen Profile sehr schnell und damit kostengünstig mit einer einzigen Vorrichtung ohne Zwischenlager und Zwischentransport hergestellt werden können.The advantage here is that they are manufactured in a continuous process Sheet metal profiles are also continuously bent on one and the same device can be and in particular via a "flying separation system" (saws, Cutting, shearing etc.) without interruption (and thus without essential Waste) can be cut to size so that the finished and curved profiles very quickly and therefore inexpensively with a single Device can be made without intermediate storage and intermediate transport can.
Die so hergestellten Fertigbiegeteile werden dann bevorzugt ebenfalls kontinuierlich über ein automatisches Handlingsystem weiter geleitet.The finished bent parts thus produced are then also preferred continuously forwarded via an automatic handling system.
Durch eine entsprechende Anordnung des Dornstangen-Biegekopfes zur Brücke lassen sich die Profile entweder links oder rechts, nach oben oder unten biegen. By arranging the mandrel bar bending head accordingly to the bridge you can bend the profiles either left or right, up or down.
Weitere vorteilhafte Ausgestaltungen sind in den Unteransprüchen definiert.Further advantageous refinements are defined in the subclaims.
Dem Walzbiegekopf vorgeschaltet ist eine Brückenkonstruktion zur Aufnahme einer beweglichen Dornstation. Diese kann über die gesamte Brückenlänge motorisch (CNC gesteuert) oder manuell bedient werden.A bridge construction for receiving is connected upstream of the roll bending head a movable mandrel station. This can span the entire length of the bridge operated by motor (CNC controlled) or manually.
Die Dornstation hat die Aufgabe über eine Dornstange das Dornschaft-Werkzeug, welches im Walzbiegekopf positioniert ist, genau auf der Biegelinie auf Position zu halten. Die ebene Brückenoberseite mit vielfältigen Befestigungsmöglichkeiten nimmt die zur Profilherstellung notwendigen Rollenstationen mit Antrieb-, Schweiß und Schleifvorrichtung, Dornstangenführungen u.a. auf. Separat schließen Bandenden-Schweißmaschine und Doppelhaspel für das Coil ab. Dem Walzbiegekopf nachgeschaltet ist eine fliegende Trennanlage.The mandrel station has the task of using a mandrel bar, the mandrel shaft tool, which is positioned in the roll bending head, exactly on the bending line hold. The flat top of the bridge with various fastening options takes the roll stations necessary for profile production with drive, welding and grinding device, mandrel bar guides etc. on. Close separately Strip end welding machine and double reel for the coil. the Downstream of the roll bending head is a flying separation system.
Die Brückenlänge richtet sich nach der Anzahl der für die Profilherstellung notwendigen Rollenstationen, mit oder ohne Schweiß-, Schleifstationen. etc. Es können auf einer RFB-Anlage nach der Erfindung die unterschiedlichsten Profile in Form und Größe hergestellt werden. Die sogenannte Umformblume eines entstehenden Profils bestimmt die Standort-Position der Dornstation. Bei einem geschlossenen Profil wird die Positionierung an dem Ort vorgenommen, an dem die Umformblume gerade noch soviel Öffnung der beiden Blechenden der Blechbandbreite zulässt, dass die Dornstangenhalterung mit der Dornstange in den sich schließenden Spalthohlraum gerade noch hinein passt. Je nach Profilform und Profilart (geschlossen, teiloffen, offen) ist die Dornstangenlänge (Maß zwischen Dornstangenhalterung und Dornschaft-Werkzeug) unterschiedlich. The bridge length depends on the number of profiles used for the manufacture of the profile necessary roller stations, with or without welding, grinding stations. etc. It can in a RFB system according to the invention, the most varied profiles Shape and size are made. The so-called forming flower one The resulting profile determines the location of the mandrel station. At a closed profile is positioned at the place where the Umformblume just as much opening of the two sheet ends of the Sheet metal strip width allows the mandrel rod holder to be in with the mandrel rod just fits into the closing gap cavity. Depending on Profile shape and profile type (closed, partially open, open) is the mandrel rod length (Dimension between mandrel holder and mandrel tool) different.
Bei offenen Profilen entfällt in aller Regel das Dornschaft-Werkzeug und somit die Dornstange. Bei teiloffenen bzw. geschlossenen Profilen sind in jedem Fall Dornschaft-Werkzeuge notwendig.In the case of open profiles, the mandrel shank tool and thus the die are generally not required Mandrel bar. With partially open or closed profiles are in any case Mandrel shank tools necessary.
Dünnwandige Blechprofile lassen sich in aller Regel mit konventionellen Biegemethoden nur sehr schwer und zumeist überhaupt nicht biegen.Thin-walled sheet metal profiles can usually be used with conventional ones Bending methods are very difficult and mostly do not bend at all.
Das Profil-Walz-Biegen ist bestens für das Freiformbiegen von gerollten Blechprofilen geeignet. Die Kombination von gerollter Profilherstellung vom Coil und dem Profil-Walz-Biegen ermöglicht erstmalig die kontinuierliche Herstellung gebogener dünn- bis dünnstwandiger Blechprofile in 2- und 3-dimensionaler Ausführung. Eine dem Biegkopf nachgestellte "Fliegende Trennanlage" mit automatischem Handlingsystem sichert den Transferablauf der Produktion.Profile roll bending is ideal for the free-form bending of rolled Suitable for sheet metal profiles. The combination of rolled profile production from the coil and profile rolling bending enables continuous production for the first time curved thin to thin-walled sheet metal profiles in 2 and 3 dimensions Execution. A "flying separation system" with the bending head automatic handling system ensures the transfer process of the production.
Gleichmäßige Bögen, Bögen mit unterschiedlichen Radien in einer Ebene, sowie 3-dimensional gebogene und mit Torsion versehene Profilbögen eröffnen mit dem RFB-Verfahren eine neue wirtschaftliche Dimension in der Herstellung.Uniform arcs, arches with different radii in one plane, as well 3-dimensional curved and torsionally shaped profile arches open with the RFB processes a new economic dimension in manufacturing.
Stoßstangen, Space Frame (großes Kfz-Seitenteil, das mehrere konventionelle Bauteile vereint), Türrahmen, Fensterrahmen, Chassis Frame im automobilen Bereich, und vieles mehr.Bumpers, space frame (large car side part, the several conventional Components combined), door frames, window frames, chassis frames in automobiles Area, and more.
Als Material für die Profile kommen bevorzugt Stähle, Aluminium, Titan und Magnesium und deren Legierungen zum Einsatz, insbesondere in der Kraftfahrzeug- und Luftfahrtbranche.Steel, aluminum, titanium and are preferred as the material for the profiles Magnesium and their alloys are used, especially in the Automotive and aerospace industries.
Selbstverständlich umfasst die Erfindung sowohl vollkommen neu aufgebaute RFB-Anlagen, die nach dem RFB-Verfahren arbeiten, aber auch den Umbau und die Ergänzung bereits bestehender Anlagen zum Herstellen von Profilen oder Anlagen zum Biegen von Profilen, je nach Anwendungsfall.Of course, the invention includes both completely new ones RFB systems that work according to the RFB process, but also the conversion and the addition of existing systems for the production of profiles or Systems for bending profiles, depending on the application.

Figur 1 zeigt eine Vorderansicht der erfindungsgemäßen Vorrichtung zum
Herstellen von Biegeprofilen aus einer Blech-Coil 1, die hier auf je einer Haspel 2
aufgewickelt ist. Das Doppelhaspel-System bietet den Vorteil, dass nur geringe
Umrüstzeiten von Coil zu Coil benötigt werden oder zwei Bleche 3 zu einem Profil
13 verarbeitet werden können. Das Blech 3 wird dann von der Haspel 2 in
Förderrichtung 4 (hier 0,6 bis 1,6 m/s Fördergeschwindigkeit) abgezogen und
zunächst einer optionalen Bandendschweißmaschine 5 zugeführt, um
anschließend in die eigentliche Profil-Formvorrichtung 6 eingeführt zu werden.
Diese Profil-Bildungsvorrichtung 6 ist aus dem Stand der Technik prinzipiell
bekannt und beinhaltet eine Reihe von Rollenstationen 7, die in Förderrichtung 4
des Blechs 3 hintereinander in Serie geschaltet sind.Figure 1 shows a front view of the device for
Manufacture of bending profiles from a sheet-metal coil 1, each on a
Zwischen den stromaufwärts befindlichen vorderen Rollenstationen 7a und den
stromabwärts befindlichen hinteren Rollenstationen 7b befinden sich die
Schweißstation 8, die Nahtschleifstation 9, die Nahtprüfstation 10, die
Kalibrierstation 11 und eine Station 12 zum Bilden von Quadrat- und
Rechteckrohren (Türkenkopf).Between the upstream
Stromabwärts hinter der letzten Rolle der hinteren Rollenstationen 7b ist der
Biegekopf 14 angeordnet, der einer zweiten Hauptkomponente der
erfindungsgemäßen Vorrichtung zum Herstellen von Biegeprofilen zugeordnet ist,
nämlich der Biegevorrichtung 18. In den Biegekopf 14 tritt das fertige aber noch
ungebogene Profil 13 aus der Profil-Formstation 6 ein. Durch 2- oder 3-dimensionales
Biegen im Biegekopf 14 wird das ungebogene Profil 13 in das
gebogene Biegeprofil 15 verformt, das dann durch die Ablängvorrichtung 16 auf
die gewünschte Länge abgetrennt wird. Die Ablängvorrichtung 16 kann
beispielsweise eine fliegende Säge sein, oder eine Schere oder eine
Schneidbrennstation oder auch Laser-Abtrennstation oder ähnliches. Wichtig ist,
dass das Abtrennorgan 17 der Ablängvorrichtung 16 sich dem gebogenen Profil
15 anpassen kann, so dass das Abtrennorgan 17 verfahrbar sein muss, 2- oder 3-dimensional.Downstream behind the last roll of the
Zur Biegevorrichtung 18 gehört noch die Dornstation 19, die in Verschieberichtung
20 verschieblich auf der Brücke 21 angeordnet ist, auf welcher Brücke 21 auch die
gesamte Profil-Formstation 6 gelagert ist. Die Längsverschieblichkeit der
Dornstation 19 ist nur außerhalb der Profilherstellung vorgesehen und ermöglicht
eine einfache und schnelle Anpassung der Anlage auf ein anderes Profil. Die
Dornstation 19 hat die Aufgabe, die Dornstange an der, dem Dornschaft (für das
Biegen) gegenüber liegenden Seite zu tragen. Die Dornstation 19 befindet sich
also an einer Stell kurz vor dem Schließen des Profils bzw. vor der Fertigstellung
des Profils. Ein Dornschaft wird nur bei geschlossenen und teilgeschlossenen
Profilen benötigt, kann aber entfallen bzw. entfernt werden für offene Profile.The bending

eine oder mehrere Dornstangenführungen 23 vorgesehen sein können. Diese
Dornstangenführungen 23 beinhalten mindestens zwei sich gegenüber liegende
mitlaufende Rollen 24, 25, die zwischen sich das zu verformende Blech 3
aufnehmen. Die eine Rolle 24 ist dabei auf der Dornstange 22 fest oder
längsverschieblich angeordnet, die andere Rolle fest oder längsverschieblich auf

der Rollenstationen 7 sitzt auf einer Verbreiterung 21 a der Brücke 21 und wird
über die Kardanwellen 28 bewerkstelligt, die die Rollen 29 antreiben. Zwischen
den Rollen 29 ist die Umformblume 30 des aus dem Rohblech 3 zu bildenden
Formprofils 13 in einigen Schritten dargestellt. Im Kern der Umformblume 30 bzw.
des Formprofils 13 ist die Dornstange 22 zu sehen die über die
Dornstangenhalterung 31 und den Kragarm 32 wieder mit der Brücke 21
verbunden ist. Der Kragarm 32 kann dabei ersetzt werden durch ein
geschlossenes Portal-Joch 33, welches dann auf beiden Seiten des Profils mit der
Brücke 21 verbunden ist. Natürlich können Kragarm 32 und Portal-Joch 33 auch

zu werden. Der Biegekopf 14 besteht aus Stützrolle 35, Walzrolle 36, Biegerolle
37 und Mittelrolle 38, wobei nur die Mittelrolle 38 angetrieben ist, die anderen
Rollen aber nur mitgetrieben sind. Die eigentliche Verformung des Profils 15
geschieht zwischen der Walzrolle 36 und der Mittelrolle 38, zwischen denen sich
der Dornschaft 39 in der Biegelinie 43, also im Kraftfluss der Presskraft befindet,
