Description

Die Erfindung betrifft eine Dressurvorrichtung zum Bearbeiten von zwei gleichzeitig parallel und nahe voneinander laufenden Drähten oder einem laufenden Draht. Der Bearbeitungsschritt kann hierbei ein Geraderichten, Ziehen oder Vorschieben des Drahtes oder Profils sein, und zwar insbesondere vor bzw. zu einer nachgeordneten anderen Bearbeitungseinrichtung, insbesondere einer Bügelbiegemaschine für Betonbewehrungsmaterial aus Stahl.The invention relates to a dressage device for processing two simultaneously parallel and close to each other running wires or a running wire. The processing step may in this case be a straightening, pulling or advancing the wire or profile, in particular in front of or to a downstream other processing device, in particular an ironing machine for concrete reinforcing material made of steel.

Die Dressurvorrichtung weist mindestens zwei antreibbare, koaxial seitlich aneinander angrenzende Rollen auf, die ein erstes von einer Welle antreibbares Rollenpaar bilden, welchem gegenüber ein zweites Paar solcher Rollen unter Bildung zweier Bearbeitungsspalte für je einen durchlaufenden Draht angeordnet ist, wobei die Rollen des zweiten Rollenpaares auf einer zur Achse des ersten Paares parallelen Achse mittels einer zweiten Welle gegenläufig antreibbar sind. Normalerweise sind drei oder vier solcher Doppelrollenpaare knapp hintereinander angeordnet und bilden so die Dressurvorrichtung.The dressage device has at least two drivable, coaxially laterally adjacent rollers, which form a first pair of rollers drivable by a shaft, opposite which a second pair of such rollers is arranged to form two machining gaps for each continuous wire, wherein the rollers of the second pair of rollers on a parallel to the axis of the first pair axis by means of a second shaft are driven in opposite directions. Normally, three or four such pairs of double rolls are arranged just behind one another and thus form the dressage device.

Nach dem Stand der Technik können die Rollenpaare jeweils fest miteinander verbunden sein, d.h. die beiden Rollen eines Paares laufen gleich schnell. Aufgrund ungleichmäßiger Abnützung einzelner Bearbeitungsspalte kann es hierbei zu verschiedenen Streckungen bzw. Längungen der beiden nahe voneinander parallel durchlaufenden Drähte kommen, die zu Problemen in der nachfolgenden Bearbeitungseinrichtung, insbesondere Bügelbiegemaschine, führen, die zwei gleich lange, nahe beieinander laufende Drähte benötigt.According to the prior art, the pairs of rollers may each be firmly connected to each other, i. the two roles of a pair are equally fast. Due to uneven wear of individual machining gaps, this can lead to different elongations or elongations of the two wires running close to each other in parallel, which lead to problems in the subsequent processing device, in particular ironing machine, which requires two wires of equal length running close to each other.

AT-A-512 898 beschreibt eine Dressurvorrichtung zum Richten von draht-, stab- oder bandförmigem langgestrecktem Stahl- oder Stahlprofilmaterial mit einem gemeinsamen Antrieb für alle Rollen, die zwangsweise antriebsmäßig aneinander gekoppelt sind. Hierbei treten dieselben Nachteile auf wie beim vorher erwähnten Stand der Technik. AT-A-512 898 describes a dressage device for straightening wire, rod or strip shaped elongate steel or steel profile material with a common drive for all Rollers forcibly coupled to each other in a driving manner. Here are the same disadvantages as in the aforementioned prior art.

Die AT-A erwähnt zwar auch, daß je eine Rolle der beiden einander gegenüber angeordneten zusammenwirkenden Rollenpaare frei von Antrieb und nur jeweils die andere Rolle der Rollenpaare angetrieben sein kann, zeigt aber keine konstruktive Lösung hierfür.Although AT-A also mentions that each one roller of the two mutually opposing cooperating pairs of rollers can be driven free of drive and only each other role of the pairs of rollers, but shows no constructive solution for this.

WO-A-2012/049244 beschreibt ebenso eine Dressur- bzw. Ziehvorrichtung für zwei gleichzeitig parallel und nahe voneinander laufende Metallprofile, wie sie eingangs beschrieben ist. Hierbei ist jeweils eine der beiden in jedem Bearbeitungsspalt zusammenarbeitenden Rollen frei von Antrieb und nur die andere Rolle jeden Rollenpaares angetrieben, indem je eine der Rollen der beiden Rollenpaare mit der jeweiligen Antriebswelle fest ist und die andere Rolle der beiden Rollenpaare auf der mit der Antriebswelle festen gelagert ist. Hierbei können zwar die beiden Antriebswellen verschieden geregelt und damit ungleichmäßige Verformungen der beiden Profile vermieden werden. Abgesehen von der Aufwendigkeit dieser Bauart ist nachteilig, daß eine von zwei in einem Verformungsspalt zusammenarbeitenden Rollen stets nur mitläuft und ihre Drehzahl so nicht von der Drehzahl der anderen, angetriebenen Rolle abweichen kann. WO-A-2012/049244 also describes a dressage or pulling device for two parallel and close to each other running metal profiles, as described above. Here, one of the two cooperating in each machining gap rollers is free of drive and only the other role of each pair of rollers driven by each one of the roles of the two pairs of rollers with the respective drive shaft is fixed and fixed the other role of the two pairs of rollers on the drive shaft is stored. In this case, although the two drive shafts can be controlled differently and thus uneven deformations of the two profiles can be avoided. Apart from the complexity of this design is disadvantageous that one of two cooperating in a deformation gap roles always only runs along and their speed so can not deviate from the speed of the other, driven role.

Die Erfindung bezweckt die Vermeidung dieser Nachteile und die Bereitstellung einer einfachen Dressurvorrichtung mit weitgehend unabhängig voneinander antreibbaren Rollen und geht aus von einer Dressurvorrichtung gemäß der genannten WO-A, mit mindestens zwei antreibbaren, koaxial seitlich aneinander angrenzenden Rollen, die ein erstes, von einer Welle antreibbares Rollenpaar bilden, welchem gegenüber ein zweites Paar solcher Rollen unter Bildung zweier Bearbeitungsspalte für je einen durchlaufenden Draht angeordnet ist, wobei die Rollen des zweiten Rollenpaares auf einer zur Achse des ersten Paares parallelen Achse mittels einer zur ersten Welle gegenläufigen zweiten Welle antreibbar sind, wobei je eine der Rollen der mindestens zwei Rollenpaare mit ihrer Antriebswelle fest verbunden und die andere Rolle der beiden Rollenpaare an der mit der Antriebswelle festen Rolle gelagert ist. Sie besteht bei einer solchen Dressurvorrichtung darin, daß jede der Rollen, welche an einer mit der Antriebswelle festen Rolle drehbar gelagert sind, an der letzteren ankuppelbar ist. Somit können entweder beide oder keine der an der anderen Rolle drehbar gelagerten Rollen mit der anderen Rolle mitlaufen, oder es kann eine beliebige an der anderen Rolle drehbar gelagerte Rolle mit der anderen Rolle mitlaufen.The invention aims at avoiding these disadvantages and at providing a simple dressage device with largely independently drivable rollers and is based on a dressage device according to said WO-A, with at least two drivable, coaxially laterally adjacent rollers, the first, of a shaft form a drivable pair of rollers, opposite which a second pair of such rollers to form two machining gaps for each one continuous wire is arranged, wherein the rollers of the second pair of rollers are driven on an axis parallel to the axis of the first pair by means of a counter-rotating shaft to the first second shaft, wherein one of the rollers of the at least two pairs of rollers firmly connected to its drive shaft and the other role of two pairs of rollers is mounted on the fixed shaft with the drive shaft. It consists in such a dressage device is that each of the rollers which are rotatably mounted on a fixed to the drive shaft roller, can be coupled to the latter. Thus either either or none of the rollers rotatably mounted on the other roller can run along with the other roller, or any other roller rotatably mounted on the other roller can run with the other roller.

Vorteilhaft drückt bei eingerückter Kupplung ein axial verschiebbares Kupplungsteil mittels einer Druckfeder auf ein mit der ankuppelbaren Rolle festes Kupplungsteil, welches die ankuppelbare Rolle mit einem mit der Antriebswelle festen Kupplungsteil verbindet.Advantageously, when the clutch is engaged, an axially displaceable coupling part presses, by means of a compression spring, onto a coupling part which is fixed with the engageable roller and which connects the engageable roller to a coupling part fixed to the drive shaft.

Bei einer weiteren Ausführungsform drückt bei eingerückter Kupplung ein axial verschiebbares Kupplungsteil mittels eines hydraulischen oder elektrischen Stellgliedes auf ein mit der ankuppelbaren Rolle festes Kupplungsteil, welches die ankuppelbare Rolle mit einem mit der Antriebswelle festen Kupplungsteil verbindet.In a further embodiment, when the clutch is engaged, an axially displaceable coupling part presses, by means of a hydraulic or electric actuator, onto a coupling part which is fixed with the engageable roller and which connects the engageable roller to a coupling part fixed to the drive shaft.

Abermals vorteilhaft ist, daß das feste Kupplungsteil die ankuppelbare Rolle mit einem mit der Antriebswelle festen Kupplungsteil mittels Reibungsschluß oder Verzahnung verbindet.It is again advantageous that the fixed coupling part connects the engageable roller with a coupling shaft fixed to the drive shaft by means of frictional engagement or toothing.

Die auf das verschiebbare Kupplungsteil einwirkende Druckfeder stützt sich auf einem an einem feststehenden Gehäuse axial festgehaltenen Widerlager ab, das sich bei eingerückter Kupplung mit der ankuppelbaren Rolle ebenso wie die Druckfeder und das verschiebbare Kupplungsteil mitdreht.The pressure spring acting on the displaceable coupling part is supported on an abutment, which is retained axially on a stationary housing and which engages when it is engaged Coupling with the coupling roller as well as the compression spring and the sliding coupling part rotates.

Dabei kann das axial verschiebbare Kupplungsteil verschoben werden mittels an einem feststehenden Gehäuse abgestützter Zylinder-Kolben-Hydraulikeinheiten, deren Kolben über axial verschiebbare Verbindungsteile an einer am axial verschiebbaren Kupplungsteil angreifenden Zugstange angreift, die am feststehenden Gehäuse axial verschiebbar und mit der ankuppelbaren Rolle nicht mitdrehend gelagert ist, wodurch die Kupplung gegen die Wirkung der Druckfeder ausrückt.In this case, the axially displaceable coupling part can be moved by means supported on a fixed housing cylinder-piston hydraulic units, the piston engages via axially displaceable connecting parts on an axially displaceable coupling part engaging tie rod, the axially displaceable on the fixed housing and not rotatably mounted with the engageable role is, whereby the clutch disengages against the action of the compression spring.

Die Rollen sind zweckmäßig zur Anpassung an den Querschnitt des jeweils durchlaufenden Drahtes profiliert.The rollers are suitably profiled to adapt to the cross section of the respective continuous wire.

Eine Vorschubeinheit gemäß der Erfindung kann in automatischen Biegemaschinen Verwendung finden. Ebenso kann sie in Drahtrichtmaschinen oder für die Zuführung von Querdrähten an automatischen Gitterschweißmaschinen eingesetzt werden.A feed unit according to the invention can be used in automatic bending machines. It can also be used in wire straightening machines or for feeding cross wires to automatic mesh welding machines.

Die Erfindung wird näher erläutert anhand eines in der einzigen Figur der Zeichnung dargestellten Ausführungsbeispieles einer Dressurvorrichtung. Von der Dressurvorrichtung, die aus mehreren, z.B. drei, hintereinander angeordneten Einheiten mit je zwei Rollenpaaren besteht, ist eine solche aus zwei Rollenpaaren bestehende Einheit gezeigt. Die beiden Rollenpaare sind jeweils gleichachsig und in einem durch beide Achsen verlaufenden Axialschnitt dargestellt.The invention will be explained in more detail with reference to an embodiment of a dressage device shown in the single FIGURE of the drawing. Of the dressage device consisting of several, e.g. three, successively arranged units each consisting of two pairs of rollers, such is shown consisting of two pairs of rollers unit. The two pairs of rollers are each equiaxed and shown in an axial section extending through both axes.

Die beiden Paare seitlich aneinander angrenzender, jeweils koaxialer Rollen 2, 3 bzw. 2', 3' arbeiten zwecks Dressieren zweier Drähte 1 bzw. 1' zusammen, welche in den zwischen den Rollenpaaren gebildeten Bearbeitungsspalten parallel nahe voneinander durchlaufen. Die Nähe ist erforderlich, da die beiden zu bearbeitenden Drähte nachfolgend gemeinsam gebogen und gemeinsam auf dieselbe Länge mittels einer einzigen Schere geschnitten werden.The two pairs of laterally adjoining, respectively coaxial rolls 2, 3 and 2 ', 3' work together for the purpose of forming two wires 1 and 1 ', which pass through each other in parallel in the machining gaps formed between the pairs of rolls. Proximity is required because the two wires to be machined are subsequently bent together and cut together to the same length with a single pair of scissors.

Die Rollen 2, 3 des ersten Paares sind von einer Welle 4 antreibbar. Die unterhalb angeordneten Rollen 2', 3' des zweiten Paares sind auf einer zur Achse des ersten Paares parallelen Achse gegenläufig mittels einer zweiten Welle 4' antreibbar.The rollers 2, 3 of the first pair are driven by a shaft 4. The rollers 2 ', 3' of the second pair arranged below are drivable in opposite directions by means of a second shaft 4 'on an axis parallel to the axis of the first pair.

Je eine 2 bzw. 2' der Rollen 2, 3; 2', 3' der mindestens zwei Rollenpaare sitzt auf der Antriebswelle 4 bzw. 4' fest; die andere Rolle 3; 3' der beiden Rollenpaare ist auf der mit der Welle 4 bzw. 4' festen Rolle 2 bzw. 2' über ein Kugellager 5 bzw. 5' drehbar gelagert. Jede der Rollen 3; 3', welche an einer mit der Welle 4 bzw. 4' festen Rolle 2 bzw. 2' gelagert ist, ist an der letzteren ankuppelbar.Depending on a 2 or 2 'of the rollers 2, 3; 2 ', 3' of the at least two pairs of rollers sitting on the drive shaft 4 and 4 'fixed; the other roll 3; 3 'of the two pairs of rollers is rotatably mounted on the with the shaft 4 and 4' fixed roller 2 and 2 'via a ball bearing 5 and 5'. Each of the rollers 3; 3 ', which is mounted on a with the shaft 4 and 4' fixed roller 2 and 2 ', can be coupled to the latter.

Die Zeichnung zeigt die eingerückte Stellung dieser Kupplung, wobei ein axial verschiebbares Kupplungsteil 6 bzw. 6' mittels einer Druckfeder 7 bzw. 7' auf ein mit der ankuppelbaren Rolle 3 bzw. 3' festes Kupplungsteil 8 bzw. 8' drückt. Das verschiebbare Kupplungsteil 6 bzw. 6' stützt sich auf einem an einem feststehenden Gehäuse 9 axial festgehaltenen Widerlager 10 bzw. 10' ab, das sich bei eingerückter Kupplung mit der Rolle 3 bzw. 3' ebenso wie die Druckfeder 7 bzw. 7' und das verschiebbare Kupplungsteil 6 bzw. 6' mitdreht. Das Kupplungsteil 8 bzw. 8' verbindet die ankuppelbare Rolle 3 bzw. 3' mittels Reibungsschluß mit einem mit der Antriebswelle 4 bzw. 4' festen Kupplungsteil 11 bzw. 11'. Die Verbindung kann auch durch Verzahnung dieser Teile hergestellt werden.The drawing shows the engaged position of this clutch, wherein an axially displaceable coupling part 6 or 6 'by means of a compression spring 7 or 7' on a with the coupling roller 3 or 3 'fixed coupling part 8 and 8' presses. The displaceable coupling part 6 or 6 'is based on a fixed housing 9 axially detained abutment 10 and 10' from which when the clutch is engaged with the roller 3 and 3 'as well as the compression spring 7 and 7' and the movable coupling part 6 and 6 'rotates. The coupling part 8 or 8 'connects the engageable roller 3 or 3' by means of frictional engagement with a drive shaft 4 and 4 'fixed coupling part 11 and 11'. The connection can also be made by toothing these parts.

Das axial verschiebbare Kupplungsteil 6 bzw. 6' ist verschiebbar mittels an dem feststehenden Gehäuse 9 abgestützter Zylinder-Kolben-Hydraulikeinheiten 12 bzw. 12'. Deren Kolben greift über axial verschiebbare Verbindungsteile 13-16 bzw. 13'-16' an einer mit ihrem Kopf am axial verschiebbaren Kupplungsteil 6 bzw. 6' anliegenden Zugstange 17 bzw. 17' an und kann so die Kupplung gegen die Wirkung der Druckfeder 7 bzw. 7' ausrücken. Die Zugstange 17 bzw. 17' ist am feststehenden Gehäuse 9 axial verschiebbar und mit der ankuppelbaren Rolle 3 bzw. 3' nicht mitdrehend gelagert. Die Druckfedern 7, 7' sind als Tellerfedern ausgebildet. Alternativ oder ergänzend kann die Anpressung auch hydraulisch oder elektrisch erfolgen.The axially displaceable coupling part 6 or 6 'is displaceable by means supported on the fixed housing 9 cylinder-piston hydraulic units 12 and 12'. Their piston engages via axially displaceable connecting parts 13-16 or 13'-16 'on a with its head on the axially displaceable coupling part 6 and 6' adjacent pull rod 17 and 17 'and can thus the clutch against the action of the compression spring. 7 respectively. 7 'disengage. The pull rod 17 or 17 'is axially displaceable on the stationary housing 9 and not rotatably mounted with the engageable roller 3 and 3'. The compression springs 7, 7 'are formed as disc springs. Alternatively or additionally, the contact pressure can also be done hydraulically or electrically.

Die Rollen 2, 2', 3, 3' sind zur Anpassung an den Querschnitt des jeweils durchlaufenden Drahtes 1 bzw. 1' profiliert, können aber je nach dem genannten Querschnitt auch flach ausgebildet sein.The rollers 2, 2 ', 3, 3' are profiled to adapt to the cross section of the respective continuous wire 1 and 1 ', but may also be formed flat depending on the said cross section.

Erfolgt die Bearbeitung des Drahtes oder Profils zum Herstellen einer geraden Anzahl fertiger Bauteile, z.B. gebogener Bügel für das Bewehren von Beton, durchlaufen zwei Drähte 1, 1' die Dressurvorrichtung. Wird eine ungerade Anzahl der fertigen Bauteile benötigt, durchläuft zusätzlich nur ein Draht 1 den zwischen den Rollen 2, 2' gebildeten Bearbeitungsspalt und stehen die Rollen 3, 3' bei ausgerückter Kupplung still. Dadurch wird Energie und Drahtmaterial gespart.If the machining of the wire or profile is to produce an even number of finished components, e.g. curved bracket for the reinforcement of concrete, pass through two wires 1, 1 'the dressage device. If an odd number of finished components is required, additionally only one wire 1 passes through the machining gap formed between the rollers 2, 2 'and the rollers 3, 3' are stopped when the clutch is disengaged. This saves energy and wire material.
