Description

Die vorliegende Erfindung betrifft eine Biegemaschine gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a bending machine according to the preamble of claim 1.

Bekannt sind Biegemaschinen, die mit Hilfe eines Biegestößels beispielsweise Stahldraht in eine "Zick-Zack" Form bringen, wobei der Stößel durch zwei Linearantriebe bewegbar ist. An einem freien Ende des Biegestößels befinden sich Biegeflächen, die gegen den Draht Druck ausüben, wobei der Draht selbst durch zwei Klemmmechanismen gehalten wird. Es ist außerdem eine Vorschubeinrichtung vorgesehen, sodass der Arbeitsrhythmus aus den Schritten Vorschieben des Drahtes, Fixierung des Drahtes durch zwei Klemmmechanismen, Biegen des Drahtes durch den Biegestößel, Lösen der Klemmmechanismen, Vorschub des Drahtes und erneut folgender Klemmung des Drahtes besteht. Dabei ist es natürlich notwendig, dass einer der Klemmmechanismen verfahrbar am Maschinenrahmen angeordnet ist, da sonst der Draht beim Biegen gedehnt würde.Bending machines are known which, for example, bring steel wire into a "zig-zag" shape with the aid of a bending ram, wherein the ram can be moved by two linear drives. At a free end of the bending ram are bending surfaces which exert pressure against the wire, the wire itself being held by two clamping mechanisms. There is also a feed device provided so that the work rhythm of the steps advancing the wire, fixation of the wire by two clamping mechanisms, bending the wire through the bending ram, releasing the clamping mechanisms, feeding the wire and again following clamping of the wire. It is of course necessary that one of the clamping mechanisms is arranged movable on the machine frame, otherwise the wire would be stretched during bending.

Nachteilig an Biegemaschinen des Standes der Technik ist, dass durch die Verwendung von zwei Linearantrieben der Beigestößel selbst stark auf Biegung beansprucht wird, weshalb dieser relativ groß dimensioniert werden muss. Ein weiterer Nachteil, der durch zwei Linearantriebe entsteht, ist, dass mit einem Aufbau nur bestimmte Biegungswinkel möglich sind. Um beispielsweise Gitterträger mit verschiedenen Geometrien zu fertigen, mussten solche Biegemaschinen des Standes der Technik aufwendig umgerüstet werden.A disadvantage of bending machines of the prior art is that the use of two linear drives of the Beigestößel itself is heavily stressed to bending, which is why this must be relatively large dimensions. Another disadvantage that arises from two linear drives, is that with a structure only certain bending angle are possible. To produce, for example, lattice girders with different geometries, such bending machines of the prior art had to be extensively converted.

Aufgabe der Erfindung ist es eine Biegemaschine bereitzustellen, die gleichzeitig materialsparender konstruiert ist und Draht in einem gegenüber dem Stand der Technik erweiterten Winkelbereich biegen kann.The object of the invention is to provide a bending machine which is designed to save material at the same time and can bend wire in an extended angle range compared to the prior art.

Diese Aufgabe wird durch eine Biegemaschine mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a bending machine with the features of claim 1.

Dies geschieht indem der Stößel durch eine erste Lagereinrichtung und durch eine zweite Lagereinrichtung translatorisch und rotatorisch bewegbar gelagert ist. Mit anderen Worten kann durch die translatorische und rotatorische Lagerung der Biegestößel immer in der Richtung der Kraft, die er auf den Draht ausüben soll, ausgerichtet werden. Dadurch wird er weniger auf Biegung beansprucht und kann deshalb kleiner dimensioniert werden.This is done by the plunger is mounted translationally and rotationally movable by a first bearing means and by a second bearing means. In other words, due to the translational and rotational bearing, the bending ram can always be aligned in the direction of the force which it is to exert on the wire. As a result, it is less subject to bending and can therefore be made smaller.

Ein weiterer Vorteil besteht in der erweiterten Anwendbarkeit. Denn durch die zusätzliche rotatorische Bewegung können erheblich mehr Biegungswinkel realisiert werden, ohne die Beigemaschine selbst vorher umbauen zu müssen. Als Resultat ist es dann möglich, dass eine Vorrichtung zur Herstellung von Gitterträgern, deren Wegemaschine erfindungsgemäß ausgeführt ist, Gitterträger beliebiger Geometrie, wie sie beispielsweise in der österreichischen Patentanmeldung A 174/2013 offengelegt wurden, hergestellt werden können.Another advantage is the extended applicability. Because the additional rotational movement significantly more bending angle can be realized without having to rebuild the Beigemaschine itself before. As a result, it is then possible that a device for the production of lattice girders whose road machine is designed according to the invention, lattice girders of any geometry, as described for example in the Austrian patent application A 174/2013 have been disclosed.

Durch die beschriebene Verbesserung, die Umbauten für verschiedene Gitterträgergeometrien eliminiert, ist es möglich, Gitterträger im Just-in-time-Verfahren herzustellen. Das heißt, diese Gitterträger können schnell auf Bestellung und in kleinen wirtschaftlichen Mengen produziert werden. Auch Losgrößen mit der Stückzahl 1 sind möglich. Die Maschine kann somit beispielsweise in ein Betonfertigteilwerk integriert werden und die jeweiligen erforderlichen Gitterträger unmittelbar vor dem Betoniervorgang bereitstellen. Bei Vorrichtungen zur Herstellung von Gitterträgern, wie sie im Stand der Technik bekannt sind, ist dies aufgrund der erforderlichen Umbauarbeiten nicht möglich und es mussten für ein rentables Wirtschaften stets größere Mengen der gleichen Gitterträger hergestellt werden, da das Umbauen ja Zeit und damit Produktivität kostet.The described improvement, which eliminates conversions for various lattice girder geometries, makes it possible to manufacture lattice girders in a just-in-time process. In other words, these lattice girders can be quickly produced to order and in small economic quantities. Also lot sizes with the quantity 1 are possible. The machine can thus be integrated, for example, in a precast concrete plant and provide the respective required lattice girders immediately before the concreting process. In devices for the production of lattice girders, as they are known in the art, this is not possible due to the required conversion work and it always had to be made for a profitable operations ever larger amounts of the same lattice girder, since the conversion yes costs time and thus productivity.

Vorteilhafte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen definiert.Advantageous embodiments of the invention are defined in the dependent claims.

Bevorzugt ist vorgesehen, dass der Stößel eine fixe, im Betrieb unveränderliche Länge aufweist. Die Bauweise kann hierdurch vereinfacht werden, da beispielsweise aufwändige Hydraulikzylinder im Stößel selbst vermieden werden.It is preferably provided that the plunger has a fixed, invariable in operation length. The design can be simplified as a result, since, for example, complex hydraulic cylinders are avoided in the ram itself.

Um gleichzeitig Hebelverhältnisse optimal auszunützen und eine Beanspruchung auf Biegung des Stößels zu vermeiden, kann es vorgesehen sein, dass die erste Lagerungseinrichtung den Stößel an einem Endbereich des Stößels anlenkt und/oder dass die zweite Lagerungseinrichtung den Stößel an einem Endbereich des Stößels anlenkt. Die Endbereiche sollten dabei nicht länger als 20 % bezogen auf eine Gesamtlänge des Stößels sein und natürlich von einem Ende des Stößels weggezählt sein, um den technischen Effekt nicht zu verlieren.In order to optimally exploit lever ratios at the same time and avoid stressing the ram, it may be provided that the first bearing device articulates the ram at an end region of the ram and / or that the second bearing device articulates the ram at an end region of the ram. The end regions should not be more than 20% of a total length of the plunger and of course be counted from one end of the plunger so as not to lose the technical effect.

Besonders einfach kann die gleichzeitige translatorische und rotatorische Lagerung des Stößels gelöst werden, indem die erste Lagerungseinrichtung einen Kurbeltrieb umfasst und/oder in dem die zweite Lagerungseinrichtung eine Schubstange umfasst.The simultaneous translational and rotational bearing of the plunger can be achieved in a particularly simple manner by the first bearing device comprising a crank drive and / or in which the second bearing device comprises a push rod.

Auf diese beiden Bewegungsformen angepasst können dann ein erster vorzugsweise rotatorischer Antrieb zur Bewegung des Kurbeltriebs und/oder ein zweiter vorzugsweise linearer Antrieb zur Bewegung der Schubstange vorgesehen sein.Adapted to these two forms of movement, a first preferably rotary drive for moving the crank mechanism and / or a second, preferably linear, drive for moving the push rod can then be provided.

Insbesondere bei der Gitterträgerherstellung ist es vorteilhaft, dass genau zwei Biegeflächen zum Biegen genau zweier Drähte vorgesehen sind, da pro Gitterträger ja genau zwei gebogene Drähte, die dann als Diagonalgurte verwendet werden, benötigt werden.In particular, in the lattice girder production, it is advantageous that exactly two bending surfaces are provided for bending exactly two wires, since each lattice girder exactly two curved wires, which are then used as diagonal straps, are needed.

Schutz wird des weiteren für eine Einrichtung zur Gitterträgerherstellung begehrt mit einer erfindungsgemäßen Biegemaschine nach einem der Ansprüche 1 bis 7 und einer Schweißeinrichtung zum Verschweißen von mittels der Biegemaschine hergestellten Diagonalgurten mit Untergurten und einem Obergurt.Protection is further desired for a lattice girder manufacturing apparatus comprising a bending machine according to any one of claims 1 to 7 and a welding device for welding diagonal belts with bottom girths and a top chord made by the bending machine.

Aufgrund seiner Materialeigenschaften ist Stahl der bevorzugte Werkstoff für die Gitterträgerherstellung.Due to its material properties, steel is the preferred material for lattice girder production.

Im Folgenden wird Bezug auf die Figuren 1, 2 und 3 genommen. In dieser Ausführungsform ist der Biegestößel 2 über eine erste Lagerungseinrichtung 11 und eine zweite Lagerungseinrichtung 12 am Maschinenrahmen 10 gelagert. Die erste Lagerungseinrichtung 11 verfügt dabei über einen Kurbeltrieb 3. Die zweite Lagerungseinrichtung 12 verfügt über eine Schubstange 7.The following refers to the FIGS. 1, 2 and 3 taken. In this embodiment, the bending ram 2 is mounted on the machine frame 10 via a first bearing device 11 and a second bearing device 12. The first storage device 11 has a crank mechanism 3. The second storage device 12 has a push rod 7.

Nach dem Vorschub des Drahtes 1 durch die Vorschubeinrichtung 9 wird der Draht 1 durch die Klemmvorrichtung 4 und die weitere Klemmvorrichtung 5 fixiert. Dies ist in Figur 1 dargestellt. Durch den Linearantrieb 14, der auf die Schubstange wirkt und den nicht dargestellten rotatorischen Antrieb 13, welcher auf den Kurbeltrieb 3 wirkt, wird der Stößel 2, an dessen freien Ende sich zwei Biegeflächen 6 befinden von unten her gegen den Draht 1 bewegt und biegt diesen dadurch. Wie in Figur 2 dargestellt ist, muss außerdem der weitere Klemmmechanismus durch einen Linearantrieb mit verfahren werden, da sonst der Draht gedehnt würde. Es ist hierbei wichtig, dass der Klemmmechanismus in genau der richtigen Geschwindigkeit mit verfahren wird, da eine Stauchung des Drahtes 1 auch unerwünscht ist.After the feed of the wire 1 by the feed device 9, the wire 1 by the clamping device 4 and the further clamping device. 5 fixed. This is in FIG. 1 shown. By the linear drive 14, which acts on the push rod and the rotary drive 13, not shown, which acts on the crank mechanism 3, the plunger 2, at the free end, two bending surfaces 6 are moved from below against the wire 1 and bends it thereby. As in FIG. 2 is shown, the other clamping mechanism must also be moved by a linear drive, otherwise the wire would be stretched. It is important that the clamping mechanism is traversed at exactly the right speed, since compression of the wire 1 is also undesirable.

In Figur 3 ist schließlich dargestellt, wie die Biegung durch den Stößel 2 beendet ist. In dieser Situation kann der Stößel 2 durch den ersten Antrieb 13 und den zweiten Antrieb 14 wieder nach unten bewegt werden, die Klemmung an den Klemmmechanismen 4, 5 kann gelöst werden und der Vorschub des Drahtes 1 kann durch die Vorschubeinrichtung 9 erfolgen. Die Biegemaschine 20 ist dann bereit für einen neuen Biegevorgang.In FIG. 3 Finally, it is shown how the bending is completed by the plunger 2. In this situation, the plunger 2 can be moved down again by the first drive 13 and the second drive 14, the clamping on the clamping mechanisms 4, 5 can be released and the feed of the wire 1 can be done by the feed device 9. The bending machine 20 is then ready for a new bending operation.

In Figur 4 ist eine perspektivische Darstellung der Biegemaschine 20 dargestellt. Hier wird deutlich, dass zwei Drähte 1 gleichzeitig gebogen werden. Dies ist insbesondere bei der Herstellung von Gitterträgern vorteilhaft, da die gebogenen Drähte 1 dann als Diagonalgurte 22 verwendet werden können, wobei sie bei einem Gitterträger paarweise benötigt werden. Wie aus dieser Figur außerdem deutlich wird, ist sowohl die Kurbel 3 als auch die Schubstange 7 in Gabelbauweise ausgeführt. Die Biegeflächen liegen dabei an einem Bolzen, der sowohl durch die Enden der gabelförmigen Schubstange 7 als auch durch ein gabelförmiges Ende des Stößels 2 geführt ist.In FIG. 4 a perspective view of the bending machine 20 is shown. Here it becomes clear that two wires 1 are bent at the same time. This is particularly advantageous in the manufacture of lattice girders, since the bent wires 1 can then be used as diagonal straps 22, where they are needed in pairs in a lattice girder. As is also apparent from this figure, both the crank 3 and the push rod 7 is executed in a forked construction. The bending surfaces lie on a bolt which is guided both by the ends of the fork-shaped push rod 7 and by a fork-shaped end of the plunger 2.

Figur 5 zeigt schematisch eine Einrichtung zur Gitterträgerherstellung. Angeliefert werden Spulen 15, auf denen geeigneter Draht aufgewickelt ist. Durch Abspulvorrichtungen 16 wird dieser abgewickelt und im Falle der Obergurte 23 und Untergurte 21 einer Richtmaschine 17 zugeführt. Derjenige Draht, der für die Diagonalgurte 22 bestimmt ist, wird der Biegemaschine 20 zugeführt. FIG. 5 shows schematically a device for lattice girder production. Supplied are coils 15, on which suitable wire is wound. By unwinding 16 this is unwound and supplied in the case of the upper straps 23 and lower straps 21 of a leveler 17. The one Wire intended for the diagonal belts 22 is fed to the bending machine 20.

Die Untergurte, der Obergurt sowie die in der Biegemaschine 20 hergestellten Diagonalgurte werden zusammen der Schweißeinrichtung 25 zugeführt, in der sie zu einem Gitterträger 24 verschweißt werden. Zweckmäßiger Weise werden die Gitterträger dann in einer Lagerstätte 18 abgelegt.The lower chords, the upper chord and the diagonal straps produced in the bending machine 20 are fed together to the welding device 25, in which they are welded to a lattice girder 24. Appropriately, the lattice girders are then stored in a reservoir 18.

Figur 6 zeigt eine Seitenansicht eines Gitterträgers. Die wichtigsten Abmessungen eines Gitterträgers sind dabei zu erkennen. Dies sind zum einen der Teilungsabstand T und die Höhe H des Gitterträgers. Wichtig sind außerdem die Winkel α und β zwischen dem Diagonalgurt 22 und dem Untergurt 21. Die erfindungsgemäße Biegemaschine erlaubt - anders als im Stand der Technik - eine völlig freie Wahl der Parameter T, H, α sowie β. Tatsächlich stellen auch stumpfe Winkel für einen der Winkel α oder β technisch kein Problem dar. Typische Werte für die Höhe H betragen 60 mm bis 450 mm. Typische Werte für die Teilungsabstände T betragen 150 mm bis 250 mm. FIG. 6 shows a side view of a lattice girder. The most important dimensions of a lattice girder can be seen here. These are, on the one hand, the pitch T and the height H of the lattice girder. Also important are the angles α and β between the diagonal 22 and the bottom flange 21. The bending machine according to the invention allows - unlike in the prior art - a completely free choice of parameters T, H, α and β. In fact, even obtuse angles for one of the angles α or β technically pose no problem. Typical values for the height H are 60 mm to 450 mm. Typical values for the pitches T are 150 mm to 250 mm.

Die vorliegende Erfindung ist nicht auf die hier dargestellte Ausführungsform beschränkt. Beispielsweise muss der Stößel 2 nicht stabförmig sein. Jegliche anderen Geometrien, insbesondere eine zu einer Sichelform gebogene, sind denkbar.The present invention is not limited to the embodiment shown here. For example, the plunger 2 need not be rod-shaped. Any other geometries, especially one bent into a sickle shape, are conceivable.
