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.

Aufbau der erfindungsgemäßen Vorrichtung (RFB-Anlage)Structure of the device according to the invention (RFB system)

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.

Profilherstellungprofile production

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.

Funktion des erfindungsgemäßen Verfahrens (RFB-Verfahren)Function of the method according to the invention (RFB method)

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.

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 reel 2 is wound up. The double reel system has the advantage that it is only minimal Changeover times from coil to coil are required or two sheets 3 to a profile 13 can be processed. The sheet 3 is then from the reel 2 in Direction of conveyance 4 (here 0.6 to 1.6 m / s conveying speed) subtracted and first fed to an optional band end welding machine 5 then to be inserted into the actual profile molding device 6. This profile forming device 6 is in principle from the prior art known and includes a number of roller stations 7, which are in the conveying direction 4th of the sheet 3 are connected in series.

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 rear roll stations 7b is the Bending head 14 arranged, which is a second main component of the device for producing bending profiles according to the invention is assigned, namely the bending device 18.

Important is, that the separating member 17 of the cutting device 16 is the curved profile 15 can adapt so that the separating member 17 must be movable, 2 or 3 dimensions.

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 device 18 also includes the mandrel station 19, which is in the direction of displacement 20 is displaceably arranged on the bridge 21, on which bridge 21 the Entire profile forming station 6 is stored.

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 mit den Füßen 26 verbunden sein oder mit jedem anderen ortsfesten Bauelement der Biegevorrichtung 18.Figure 4 shows an enlarged detail view of the invention Device for producing bending profiles according to Figure 1. The bridge 21 is open Feet 26 mounted and carries the roller stations 7. The drive 27 for the rollers the roller stations 7 sits on a widening 21 a of the bridge 21 and is accomplished via the cardan shafts 28 which drive the rollers 29. Between the rollers 29 is the forming flower 30 of the one to be formed from the raw sheet 3 Form profile 13 shown in a few steps. At the core of the Umformblume 30 or of the shaped profile 13, the mandrel rod 22 can be seen on the Mandrel bar holder 31 and the cantilever 32 again with the bridge 21 connected is. The cantilever arm 32 can be replaced by a closed portal yoke 33, which is then on both sides of the profile with the Bridge 21 is connected. Of course, the cantilever arm 32 and portal yoke 33 can also be connected to the feet 26 or to any other stationary component the bending device 18.

Der Längsantrieb der Dornstation 19 in den Bewegungsrichtungen 20 wird dabei durch den Antrieb 34 durchgeführt.The longitudinal drive of the mandrel station 19 in the directions of movement 20 performed by the drive 34.

Figur 5 zeigt eine vergrößerte Detaildarstellung eines Teils des Biegekopfes 14 der Biegevorrichtung 18, die an sich bereits aus dem Stand der Technik bekannt ist und auf den gleichen Anmelder zurück geht.FIG. 5 shows an enlarged detailed illustration of a part of the bending head 14 the bending device 18, which is already known per se from the prior art is and goes back to the same applicant.

Das gefertigte Profil 13 wird in Förderrichtung 4 in den Biegekopf 14 eingeführt, und tritt als Biegeprofil 15 stromabwärts aus, um der Ablängstation 16 zugeführt 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, welcher Dornschaft 39 sich am anderen Ende der Dornstange 22 befindet, gegenüber der Dornstation 19.The finished profile 13 is introduced into the bending head 14 in the conveying direction 4, and emerges as a bending profile 15 downstream to the cutting station 16 to become. The bending head 14 consists of support roller 35, roller roller 36, bending roller 37 and center roller 38, only the center roller 38 being driven, the others Roles are only driven. The actual deformation of the profile 15 happens between the roller 36 and the central roller 38, between which there is the mandrel shaft 39 is located in the bending line 43, that is to say in the force flow of the pressing force, which mandrel shaft 39 is located at the other end of the mandrel bar 22, opposite the mandrel station 19.

Durch Auswalzen des Materials des Profils 13 an der Walzrolle 36 wird die neutrale Faser aus der Mitte des Profils 13 nach unten bis hin zur Mittelrolle 38 verlagert, so dass damit bereits eine Biegung des Profils 13 allein erfolgt, die durch die Biegerolle 37 nur noch unterstützt wird und auf einen definierten Wert justiert wird. Hierdurch können auch sehr dünnwandige Profile 13 mit hoher Präzision und Qualität gebogen werden, ohne dass es zu Oberflächenverformungen (Orangen- Effekt) oder gar zum Reißen des Materials kommt.By rolling out the material of the profile 13 on the roller 36 neutral fiber from the center of the profile 13 down to the center roll 38 relocated, so that there is already a bending of the profile 13 alone is only supported by the bending roller 37 and to a defined value is adjusted. This allows very thin-walled profiles 13 with high Precision and quality can be bent without losing it Surface deformation (orange effect) or even to tear the material comes.

Der Dornschaft 39 wird bevorzugt gekühlt durch eine aus dem Stand der Technik bekannte Mikroschmierung 40 (Figur 4), die über den Kragarm 32 bzw. das Portal 33 der Dornstation 19 und über die Dornstangenhalterung 31 und der Dornstange 22 dem Dornschaft 39 zugeführt wird. Am Dornschaft 39 befinden sich dann verschleißarme Härtungen bzw. gehärtete auswechselbare Platte, an die das Schmier-/Kühlmittel geleitet wird.The mandrel shaft 39 is preferably cooled by one from the prior art known micro-lubrication 40 (Figure 4), the cantilever 32 or the portal 33 of the mandrel station 19 and the mandrel rod holder 31 and the mandrel rod 22 is fed to the mandrel shaft 39. Then on the mandrel 39 are low wear hardening or hardened replaceable plate to which the Lubricant / coolant is passed.

Die Walzrolle 36 und die damit zusammenwirkende Mittelrolle 38 sind in den Zustellrichtungen 41 aufeinander zu bewegbar, zur Einstellung der Kraft auf das Profil 13. Die Stützrolle 35 und die Biegerolle 37 sind ebenfalls in den Zustellrichtungen 41 in Richtung des Profils 13 bzw. des Biegeprofils 15 zustellbar, zusätzlich aber noch senkrecht dazu in den Zustellrichtungen 42. The roller 36 and the cooperating central roller 38 are in the Infeed directions 41 can be moved towards one another to adjust the force on the Profile 13. The support roller 35 and the bending roller 37 are also in the Infeed directions 41 in the direction of profile 13 or bending profile 15, additionally, however, perpendicular to it in the feed directions 42.
