Description

Richtrolieneinheit  Richtrolieneinheit
Die Erfindung betrifft eine Richtrolleneinheit für öraht-, stab- oder bandförmiges Richtqut aus Stahl, insbesondere Dräh- te, Stäbe, Profile, Bänder, mit paarweise zusammenwirkenden Richtrollen, die gegen das Richtgut ansteilbar und von diesem lüftbar sind. The invention relates to a straightening roller unit for wire, rod or strip-shaped Richtqut of steel, in particular wires te, rods, profiles, bands, with pairwise cooperating straightening rollers, which can be attached to the straightening and be ventilated by this.
Aufgrund der immer höher werdenden Anforderungen an die Energieeffizienz von Maschinen und Anlagen zum Richten von derartigem Richtgut wurde auf dem Gebiet des Rollenrichtens mit Vorschubrollen die Energiebilanz überprüft, Ergebnis dieser Untersuchung ist, daß ein wesentlicher Teil der eingesetz¬ ten Energie durch Walz- und Reibungsverluste, verursacht durch die Antriebsräder bzw. Antriebsrollen, verloren geht. Des wei- teren ist der Energieanteil zur Beschleunigung dieser An- triebseinheiten aufgrund der Massenträgheit erheblich. Due to the ever increasing demands on the energy efficiency of machines and equipment for straightening such straightening goods, the energy balance has been examined in the field of roller alignment with feed rollers, the result of this investigation is that a substantial part of the energy ¬etz¬ by rolling and friction losses, caused by the drive wheels or drive rollers, lost. Furthermore, the energy component for accelerating these drive units is considerable due to the inertia of mass.
Die Erfindung zielt darauf ab, eine verbesserte Richtrolleneinheit zu schaffen, die beispielsweise einer Drahtbiegeanlage vorgeschaltet wrrd und mit geringerem Energieaufwand als bisher betrieben sowie zum Bearbeiten von rundem oder eckigem, stabförmigem oder in Wickelform vorliegendem Richtgut verwenden werden kann. Die Erfindung erreicht dies dadurch, daß die Richtrollen angetrieben sind und die für den Richtvorgang benötigte Vorschubkraft durch Reibung der Richtrollen in das Richtgut eingebracht wird.  The invention aims to provide an improved straightening roller unit which, for example, precedes a wire bending machine and which can be operated with less energy than before and can be used for machining of round or angular, rod-shaped or strip-shaped straightening material. The invention achieves this by the fact that the straightening rollers are driven and the feed force required for the straightening process is introduced by friction of the straightening rollers in the straightening.
Bei der Erfindung entfallen somit die bisher verwendeten gesonderten Antriebsräder. Die für den RiehtVorgang benötigte Vorschubkraft wird vielmehr direkt über die Rieht rollen selbst aufgebracht .  The invention thus eliminates the previously used separate drive wheels. The feed force required for the RiehtVorgang is rather applied directly over the Rieht roll itself.
ErfindungsgemäS sind die Richtroller: einzeln oder gemein¬ sam antreibbar. Vorzugsweise ist vorgesehen, daß die Richtrollen mit zuge¬ ordneten Antriebselementen gekuppelt sind, die von einer An¬ triebsvorrichtung über ein Antriebskraft-Ver eilgetriebe antreibbar sind. ErfindungsgemäS the Rich Troller include individually or in common ¬ sam driven. It is preferably provided that the leveling rollers are coupled with added ¬ associated drive elements eilgetriebe of an on ¬ drive device via a drive force can be driven Ver.
Nach einera weiteren Erfindungsmerkmal ist die Anstellung der Richtrollen an das Riehtgut ohne Unterbrechung des VorschubkraftSchlusses ausführbar .  After aa further feature of the invention, the employment of the straightening rollers on the Riehtgut without interrupting the VorschubkraftSchlusses executable.
Im Rahmen der Erfindung können die Richtrollen einzeln von Hand oder motorgetrieben an das Richtgut angestellt und von diesem gelüftet werden.  In the context of the invention, the straightening rollers can be made individually by hand or motorized to the straightening and be ventilated by this.
Alternativ sind alle Richtrollen von Hand oder über eine rootorgetriebene ZentralverStelleinrichtung gemeinsam an das Richtgut anstellbar und von diesem lüftbar,  Alternatively, all straightening rollers can be adjusted by hand or by means of a rooter-driven central adjustment device together with the straightening material and can be ventilated therefrom,
Die R eht rollen können somit im Rahmen der Erfindung je nach Richtgutgeometrie und Richtergebnis einzeln manuell oder motorgetrieben bzw. gemeinsam manuell oder motorgetrieben an das Riehtgut angestellt werden.  The R eht rollers can thus be employed in the context of the invention, depending on Richtgutgeometrie and directional result individually manually or motorized or jointly manually or motor driven to the Riehtgut.
Die Bearbeitung des Riehtgutes kann im Einzeldurchlauf oder Para lleidurcbiauf erfolgen.  The processing of the Riehtgutes can be done in a single pass or Para lleidurcbiauf.
Alle Antriebs- und AnsteilVorgänge sind mittels einer Programmsteuereinrichtung ausführba ,  All drive and AnsteilVorgänge are executed by means of a program control device,

Die dargestellte Rieht rclleneinneit ist zum Geradrichten von langges recktem Richtgut 1 bestimmt, wie Drähte, Stäbe, Profile, Eänder usw. Das Richtgut 1 kann eckigen oder runden Querschnitt haben und abgelängt bzw. in Stabform oder vvickei- form vorliegen. Ein aus im wesentlichen drei miteinander verbundenen Platten 2*, 2", 2'" bestehendes Gehäuse 2 (Fig. 3} nimmt ein oder mehrere in Vorschubrichtung P hintereinander geschaltete Paare von oberen und unteren Richtrollen 6 auf, die zu beiden Seiten einer Richtgutvorschubebene angeordnet sind. Eine an der Außenseite der einen Gehäuseplatte 2" montierte, z.B. elektrische AntriebsVorrichtung 3 dient zum An- trieb einer nachfolgend erläuterten Getriebe orriehtung 4 zum verteilen der von der Antriebsvorrichtung 3 aufgebrachten Vorschubkraft auf die einzelnen Richtrollen 6.  The illustrated directional center is intended for straightening longitudinally straightened straightening material 1, such as wires, bars, profiles, edges, etc. The straightening material 1 can have an angular or round cross-section and can be cut to length or in rod form or in the form of a vise. A housing 2 consisting of essentially three interconnected plates 2 *, 2 ", 2 '" (FIG. 3) accommodates one or more pairs of upper and lower straightening rollers 6 connected in series in the feed direction P, which are arranged on both sides of a feedstock feed plane An electric drive device 3 mounted on the outside of a housing plate 2 "serves to drive a gear unit 4 explained below for distributing the feed force applied by the drive device 3 to the individual straightening rollers 6.
Ferner sind im Gehäuse 2 eine von Hand oder motorisch betätigte EinzelverStelleinrichtung 7 und eine von Hand oder mo- torisch betätigte Zentralverstelleinrichtung S für die Richtroilen 6 angeordnet. Die Motorbetätigung wird über eine nicht gezeigte Prograrnmsteuereinrichtung angesteuert. Das Gehäuse 2 dient zugleich zum Schutz gegen Schmutz und d r mechanischen Beschädigungen, z.B. durch das Riehtgut 1- Die von der nicht gezeigten Prograrnmsteuereinrichtung an¬ gesteuerte Antriebs orrichtung 3 weist ein Antriebszahnritzel 5 für die Verteil -Getriebevorrichtung 4 auf, welche ausgehend von einem Verteilzahnrad 5' und einer in einer mittleren Gehäuseplatte 2 !" gelagerten Zwisohenzahnwelle 5" die Antriebs- leistung des Äntriebszahnrades 5 über eine Reihe von miteinander kararnenden Zahnrädern 4' auf die zugeordneten Richtrolien 6 verteilt. Beim gezeigten Beispiel sind alle Richtrollen 6 angetrieben. Bei einer nicht gezeigten Ausführungsform können die Zahnräder 4' einzeln angetrieben werden. Anstelle der Zahnräder 4' können z.B. auch Riemen vorgesehen sein. Further, in the housing 2, a manual or motor-operated EinzelverStelleinrichtung 7 and a manually or motor-operated Zentralverstelleinrichtung S for the Richtroilen 6 are arranged. The engine operation is controlled via a programmer, not shown. The housing 2 also serves to protect against dirt and dr mechanical damage, for example by the Riehtgut 1- The programmer of the programmer not shown on ¬ controlled drive orrichtung 3 has a drive pinion gear 5 for the distribution gear 4, which starting from a Verteilzahnrad 5 'and one in a middle housing plate 2 ! "mounted Zwisohenzahnwelle 5" the drive power of the Äntriebszahnrades 5 distributed over a series of carrousel with each other gear wheels 4 'on the associated Richtrolien 6. In the example shown, all straightening rollers 6 are driven. In an embodiment not shown, the gears 4 'can be driven individually. Instead of the gears 4 'may for example also be provided belt.
Die Geometrie dieser Verteü-Getriebevorrichtung 4 ist so gewählt, daß die abtr iebsseitig angeordneten oberen Richtrol¬ len 6 den Erfordernissen der Richtgeometrie und de Riehtqua- lität sowie der Vorschubkraf entsprechend unabhängig voneinander oder gemeinsam an das Richtgut 1 angestellt werden können, ohne dabei den Vorschubkraftschluß zu verlieren bzw. zu unterbrechen. The geometry of this transfer gear device 4 is chosen so that the abtr iebseitig arranged upper Richtrol ¬ len 6 the requirements of Richtgeometrie and de Riehtqua- quality and the feed force independently or together to the Richtgut 1 can be employed without the Vorschubkraftschluss to lose or to interrupt.
Die Richtrollen 6 sind als Doppelspur-Richtlinien ausge¬ bildet,, wobei die unteren Richtrolien 6 in einem in der Gehäu¬ seplatte ' drehbar gelagerten Lagergehäuse 6* gelagert sind, wogegen das obere Lagergehäuse 6" mit den darin gelagerten oberen Richtrolien 6 über die beiden Schwingen 14 mit dem unteren Lagergehäuse 6' fest verbunden ist, wie die Fig. 2 und 5 illustriere . The straightening rollers 6 are designed as double track guidelines ¬ forms, wherein the lower Richtrolien 6 are stored in a housing housing ¬ rotatably mounted in the rotatably mounted bearing housing 6 *, whereas the upper bearing housing 6 "with the therein stored upper Richtrolien 6 on the two Swing 14 is fixedly connected to the lower bearing housing 6 ', as Figs. 2 and 5 illustrate.
Die oberhalb des Richtgutes 1 angeordneten Richtrolien 6 und Antriebs Zahnräder 4" sind über die Einzelverstelieinrich- tung 8' und über die Lagergehäuse 6" mit den Versteileinrichtungen 7, 8 verbunden. Der Drehmittelpunkt 4" der Einzelversteileinrichtung 8' ist so positioniert, daß bei Zustellung der Richtrollen 6 an das Richtgut 1 die Zahnräder 4 ' immer im Eingriff sind.  The arranged above the Richtgutes 1 directional grooves 6 and drive gears 4 "are connected via the Einzelverstelieinrich- device 8 'and the bearing housing 6" with the adjustment devices 7, 8. The center of rotation 4 "of the individual adjusting device 8 'is positioned so that upon delivery of the straightening rollers 6 to the straightening 1, the gears 4' are always in engagement.
Diese Konstruktion ermöglicht es, das gesamte Verteilgetriebe 4 im Sinne der Pfeile P2, P3 (Fig. 1) um Lagerpunkte zu verschwenken, die gemäß Fig. 5 durch die Achsen 4" der in der Gehäusehauptplatte 2 ' gelagerten oberen Richtrollen 6 defi¬ niert sind. This construction makes it possible to pivot the entire distribution gear 4 in the direction of the arrows P2, P3 (FIG. 1) about bearing points which, according to FIG Housing main plate 2 'mounted upper straightening rollers 6 are defi ¬ ned.
Die zugleich als Vorschubelemente für das Richtgut 1 die¬ nenden Richtrollen 6 können mit glatter, aber auch zur Erhö- hung der Reibung mit profilierter Oberfläche ausgeführt werden. Insbesondere kann das Profil der Richtrollen 6 V-Form, wie beim gezeigten Äusführungsbeispiel, Kreisform, Ellipsen¬ form oder eine beliebige andere Form haben. The same direction as feed elements for the Richtgut 1 ¬ nenden straightening rollers 6 can be performed with smooth, but also to increase the friction with profiled surface. In particular, the profile of the straightening rollers 6 V-shape, as shown in the exemplary embodiment shown, circular shape, elliptical ¬ form or any other shape.
Die Verstellung bzw. Anstellung der Richtrollen 6 an das Richtgut 1 erfolgt quer zur Vorschubrichtung (Pfeil P4 in Fig. 4) , beim dargestellten Beispiel über die Zentralverstelleinrichtung 8 und die Einzelverstelleinrichtung 8'. Alternativ dazu ist auch eine lineare Zustellung möglich.  The adjustment or employment of the straightening rollers 6 to the straightened material 1 takes place transversely to the feed direction (arrow P4 in Fig. 4), in the example shown on the Zentralverstelleinrichtung 8 and the Einzelverstelleinrichtung 8 '. Alternatively, a linear delivery is possible.
Die oberen Richtrollen 6 können auch einzeln von Hand oder motorisch im. Sinne des Pfeiles PI in Fig. 1 über die Verstell- Spindel 7 an das Richtgut 1 angestellt v/erden.  The upper straightening rollers 6 can also individually by hand or motor in. Meaning of the arrow PI in Fig. 1 employed on the adjusting spindle 7 to the straightening 1 v / ground.
Wenn alle Richtrollen 6 über das in der Gehäusehauptplatte 2' bei 9 ' gelagerte zentrale Stellglied 9 de Zentralverstell¬ einrichtung 8 motorisch gemeinsam im Sinne des Pfeiles P3 in Fig. 1 angestellt werden, wird beispielsweise der Einfädeivor- gang des Richtgutes 1 erleichtert. Das Stellglied 9 kann als Hydraulikzylinder oder Elektromotor usw. ausgebildet werden. Die Einstellwerte für die verschiedenen Richtgüter der Ver- stei ieinrichtungen. 7, 8, die über die nicht gezeigte Programm- Steuereinrichtung angesteuert werden, können im Teil- oder Vo11automat ikbetrieb in der Steuereinrichtung gespeichert wer¬ den, so daß sie bei oftmaligem Wechsel des Richtgutes 1 rasch wiederhergestellt werden können. When all the straightening rollers are hired 6 via the bearing in the housing main plate 2 'at 9' central actuator 9 de Zentralverstell ¬ device 8 motor together in the direction of the arrow P3 in Fig. 1, the Einfädeivor- example gear facilitates the straightened 1. The actuator 9 may be formed as a hydraulic cylinder or electric motor, etc. The setting values for the different straightening devices of the crushers. 7, 8, which are driven via the not-shown program control means can ikbetrieb in partial or Vo11automat in the control device ¬ the stored so that they can be restored rapidly case of frequent change of the material to be straightened. 1
Das Stellglied 9 der Zentral ersteileinrichtung 8 kann auch je nach den Erfordernissen von Hand, z.B. mittels einer Handkurbel oder motorisch über Handtaster sowie mittels de übergeordneten Programmsteuereinrichtung betätigt werden. Ein weiteres am Gehäuse 2 abgestütztes hydraulisches Stellglied 10 (Fig. 3) dient zum Verstellen der Rieht rollen 6 quer zur Richtebene im Sinne des Pfeiles P10 in Fig. 3, Auch dieses Stellglied 10 kann statt hydraulisch betätigbar für ma- nuellen oder elektromotorischen Betrieb ausgeführt werden, wobei auch seine Funktionsweise mittels der Programmsteuerein¬ richtung geregelt werden kann. Es dient zugleich zum Kompensieren eventuell auftretender Torsionsspannungen im Richtgut 1. Schließlich ist einlaufseitig auch eine Rückzugkleramein- richtung 13 für das Richtgut 1 vorgesehen. The actuator 9 of the central ersteileinrichtung 8 can also be operated depending on the requirements of hand, for example by means of a hand crank or motorized by hand and by de parent program control device. Another supported on the housing 2 hydraulic actuator 10 (Fig. 3) is used to adjust the Rieht rollers 6 transversely to the directional plane in the direction of arrow P10 in Fig. 3, Also this actuator 10 can be carried out instead of hydraulically actuated for manual or electric motor operation be, with its operation can be controlled by means of Programmsteuerein ¬ direction. At the same time, it serves to compensate for any torsional stresses that may occur in the straightening material 1. Finally, a retraction sclera device 13 for the straightening material 1 is also provided on the inlet side.
Die Fig. 6 bis 8 illustrieren den Betrieb der Richteinheit zum Richten zweier parallel in Doppelspur-Richtrollen 6 ge¬ führten Drähten 11, 12. Dabei ist es zur Speisung einer nachgeordneten Drahtbiegemaschine häufig erforderlich, eine unge- rede Anzahl von Drähten zu richten. Hiezu kann erfindungsgemäß abwechselnd der Antrieb eines Paares von Richtrollen 6 stillgesetzt werden. Gemäß Fig. 7 wird der Draht 11 gerichtet, wogegen der Draht 12 stillsteht und die zugeordneten Richtrollen 6 in Lagern 15 leer mitlaufen. In Fig. 3 ist die Situation um- gekehrt. FIGS. 6 to 8 illustrate the operation of the rectifying unit for directing two parallel double-track straightening rollers 6 ge ¬ lead wires 11, 12. In this case, it is often necessary to feed a downstream wire bending machine to send a un- talk number of wires. For this purpose, according to the invention alternately the drive of a pair of straightening rollers 6 are stopped. According to Fig. 7, the wire 11 is directed, whereas the wire 12 is stationary and the associated straightening rollers 6 run in bearings 15 empty. In Fig. 3, the situation is reversed.
Die erfindun sgemäße Richteinheit ist imstande, das Richt¬ gut 1 exakt in Position zu halten, unabhängig von der Anzahl der Richtspuren, und ermöglicht es ferner, die Vorschubrichtung umzukehren. Zum Einfädeln des Richtgutes 1 kann vor und/ oder hinter der Richteinheit eine nicht gezeigte Treibvorrichtung vorgesehen werden. The erfindun sgemäße straightening unit is able to hold the directional ¬ well 1 exactly in position, regardless of the number of target tracks, and also makes it possible to reverse the feed direction. For threading the Richtgutes 1 can be provided before and / or behind the straightening unit, a driving device, not shown.
Im Rahmen der Erfindung kann die Bahn des Richtgutes 1 eine beliebige Bahnkurve sein, weicher die zum Richten erforderlichen Zustellungen überlagert werden,  In the context of the invention, the path of the straightening material 1 can be any trajectory which superimposes the notches required for straightening,
Es versteht sich, daß die Erfindung im. Rahmen des Erfindungsgedankens verschiedentlich abgewandelt werden kann, ins- besondere, was die Ausbildung der Antriebe und die Richtrollengeometrie betrifft . It is understood that the invention in. Can be variously modified within the scope of the inventive idea, in special, concerning the design of the drives and the straightening roller geometry.
Beispielsweise kann die Richtrolleneinheit beim Richten von Drähten einen gängigen Ricntgutdurch esserbereich von 3 - 20 mm abdecken. Bei Richtvorrichtungen liegt der Durchmesserbereich der Richtrollen. 6 üblicherweise zwischen 50 und 150 mm .  For example, when straightening wires, the straightening roller unit can cover a common radius range of 3 to 20 mm. For straightening devices, the diameter range of the straightening rollers is. 6 usually between 50 and 150 mm.
Die Erfindung ist derart inodular aufgebaut, daß eingangs- seitig, je nach den Erfordernissen, Elektro-, Hydraulik-, Pneumatikmotoren und Klinkenantriebe direkt oder über Getriebe mit fixer oder auch variabler Übersetzung, z.B. ein Schaltgetriebe, vorgesehen werden können.  The invention is of such an in modular design that, on the input side, depending on the requirements, electric, hydraulic, pneumatic motors and jack drives are provided directly or via transmissions with fixed or variable ratio, e.g. a manual transmission, can be provided.
