Abstract

The invention presents a solution with which it is possible in straightening machines, which have six or more straightening rolls (7 to 12), for wire or tubes, arranged skew with respect to the direction of passage of the workpiece to extend the diameter range beyond the lower limit of the workpiece diameters to be straightened according to the prior art. For this purpose, guide nozzles (34, 35) for the workpieces, which bridge the gap between the rolls and guide the workpiece there, are provided between the sequential straightening rolls or groups of rolls. The nozzles are fastened to support arms (26, 27) which project from the edge of the machine as far as between the straightening rolls. The support arms can be removed. The nozzles are used only in straightening the smallest diameters. The support arms with the nozzles can be adjusted in height. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Richtmaschine mit 6 oder mehr zur Durchlaufrichtung des Werkstücks schräg gestellten konkaven Richtrollen. Auf diesen Richtmaschinen werden meistens Rohre gerichtet. Je kleiner der Rohrdurchmesser und je dünner die Wandstärke der Rohre wird, desto häufiger finden die Werkstücke nicht den richtigen Weg durch die Richtmaschine. Zur Vermeidung dieses Umstandes wurden bisher stets die Abstände zwischen den Richtrollen bzw. Richtrollengruppen so klein wie möglich gehalten.The invention relates to a straightening machine with 6 or more concave straightening rollers inclined to the direction of the workpiece. Pipes are usually straightened on these straightening machines. The smaller the pipe diameter and the thinner the wall thickness of the pipes, the more often the workpieces cannot find the right way through the straightening machine. In order to avoid this circumstance, the distances between the straightening rolls or straightening roll groups have always been kept as small as possible.

Andererseits ist es bei Zweiwalzenrichtmaschinen bekannt zwischen die meistens übereinander angeordneten Richtwalzen Führungslineale einzubringen, um die Werkstücke beim Richtvorgang seitlich abzustützen und so die Durchlaufrichtung des Drahtes oder der Stangen zu gewährleisten.On the other hand, in the case of two-roll straightening machines, it is known to introduce guide rulers between the straightening rolls, which are usually arranged one above the other, in order to support the workpieces laterally during the straightening process and thus to ensure the direction of travel of the wire or rods.

Es ist Aufgabe der vorliegenden Erfindung, die Führung von Werkstücken, insbesondere Rohren kleinen Durchmessers, zwischen aufeinanderfolgenden Richtrollen oder Richtrollengruppen zu verbessern. Dies geschieht mit dem Ziel, den Arbeitsbereich von Rohrrichtmaschinen zu vergrößern.It is an object of the present invention to improve the guidance of workpieces, in particular small diameter tubes, between successive straightening rolls or straightening roll groups. This is done with the aim of increasing the work area of pipe straightening machines.

Die Lösung dieser Aufgabe ist im kennzeichnenden Teil von Anspruch 1 wiedergegeben. Damit wird ein Ausweichen insbesondere knickempfindlicher Rohre zwischen aufeinander- . folgenden Richtrollen oder Richtrollengruppen vermieden. Zur Vereinfachung wird im folgenden die Beschreibung der Erfindung anhand einer Sechswalzenrichtmaschine vorgenommen, wobei alle Walzen schräg zur Durchlaufrichtung des Werkstücks angestellt sind und wobei jeweils zwei Walzen übereinander angeordnet sind, so daß sich drei hintereinander angeordnete Gruppen von je zwei Walzen ergeben. Die Erfindung soll jedoch nicht auf solche Richtmaschinen beschränkt sein.The solution to this problem is given in the characterizing part of claim 1. Thus, a dodging particular knickem p findlicher pipes between successive. following straightening rollers or Richtrollengru p pen avoided. For simplification, the description of the invention is made below with the aid of a six-roll straightening machine, with all the rolls being inclined to the direction of travel of the workpiece and with two rolls being arranged one above the other, so that there are three groups of two rolls arranged one behind the other. However, the invention should not be limited to such straightening machines.

Bei einer derartigen Maschine tritt das Werkstück aus den ersten zwei Richtrollen aus, ohne eine abschließende Richtwirkung erfahren zu haben. Deshalb ist der genaue Punkt an dem das Werkstück aus den ersten beiden Richtwalzengruppen austritt nicht mit Sicherheit vorherzusehen. Dem trägt die Ausgestaltung der Erfindung nach Anspruch 2 im besonderem Maße Rechnung. In dem Einlauftrichter wird das Werkstück auf den angestrebten Durchlaufpfad zentriert. Es kommt hinzu, daß bei verschiedenen Winkelstellungen der Richtwalzen sich ein hinzunehmender Abstand zwischen den Führungsdüsen und den Ort des Austritt des Werkstücks aus den vorangegangenen Richtwalzen einstellt, so daß auch aus diesem Grunde ein Einfuhrtrichter an den Führungsdüsen wünschenswert ist.In such a machine, the workpiece emerges from the first two straightening rollers without having experienced a final straightening effect. Therefore, the exact point at which the workpiece emerges from the first two straightening roller groups cannot be predicted with certainty. The configuration of the invention according to claim 2 takes this into account to a particular extent. The workpiece is centered on the desired flow path in the feed hopper. In addition, there is an additional distance between the guide nozzles and the location of the exit of the workpiece from the previous straightening rollers at different angular positions of the straightening rollers, so that an insertion funnel on the guide nozzles is also desirable for this reason.

Bei der Ausführung entsprechend Anspruch 3 ist zu berücksichtigen, daß diese Maßnahme nur für den kleinsten Anstellwinkel der Rollen gilt, wobei dieser kleinste Anstellwinkel jedoch ohnehin bei den kleinsten Werkstückdurchmessern eingestellt wird, so daß im Falle, wenn die Führungsdüsen von Bedeutung sind, diese Walzenstellung gegeben ist.In the embodiment according to claim 3 it should be taken into account that this measure applies only to the smallest angle of attack of the rollers, this smallest angle of attack being set anyway for the smallest workpiece diameters, so that in the case when the guide nozzles are important, this roller position is given is.

Die Präzisierung der Erfindung gemäß Anspruch 4 soll insbesondere eine Abgrenzung gegenüber solchen Führungsdüsen sicherstellen, die vor oder hinter der Richtmaschine Anwendung finden könnten. Mit der vorliegenen Erfindung werden nur die Führungsdüsen beansprucht, die zwischen den Richtwalzen einer Richtmaschine angeordnet sind. Die so gekennzeichneten Führungsdüsen dienen der überbrückung der Zwischenräume zwischen den Richtrollen.The clarification of the invention according to claim 4 is intended in particular to ensure delimitation from those guide nozzles that could be used in front of or behind the straightening machine. With the present invention, only the guide nozzles which are arranged between the straightening rolls of a straightening machine are claimed. The guide nozzles marked in this way serve to bridge the gaps between the straightening rollers.

Mit der Ausgestaltung der Erfindung nach Anspruch 5 wird erreicht, daß die Befestigung der Führungsdüsen gut zugänglich ist, damit diese beim Richten von Werkstücken mit großem Durchmesser entfernt werden können. Die Düsen sind mit ihrem Durchtrittsquerschnitt, daß heißt ihrem minimalen inneren Durchmesser den Werkstücken des kleinsten Durchmesserbereichs der Richtmaschine angepaßt. Sie müssen deshalb beim Richten großer Durchmesser aus dem Walzenbereich genommen werden.With the embodiment of the invention according to claim 5 it is achieved that the attachment of the guide nozzles is easily accessible so that they can be removed when straightening workpieces with a large diameter. With their passage cross-section, that is to say their minimum internal diameter, the nozzles are adapted to the workpieces of the smallest diameter range of the straightening machine. They must therefore be removed from the roller area when straightening large diameters.

Neben einer einfachen Steckverbindung zwischen den Tragarmen und dem Maschinengestell ist vorzugsweise' die Weiterbildung gemäß Anspruch 6 vorgesehen.In addition to a simple plug connection between the support arms and the machine frame, the further development according to claim 6 is preferably provided.

Eine Höhenvorstellung der Düsen nach Anspruch 7 dient der Anpassung an unterschiedliche Durchbiegungen des Werkstücks und der Anpassung an unterschiedliche Walzendurchmesser, die sich durch Verschleiß und Nachschleifen ergeben können.An elevation of the nozzles according to claim 7 is used to adapt to different deflections of the workpiece and to adapt to different roller diameters, which can result from wear and regrinding.

Die Auswechselbarkeit der Düsen nach Anspruch 8 begünstigt eine Anpassung des Düsen - Innendurchmessers an den Durchmesser der zu richtenden Werkstücke und erlaubt weiterhin eine einfache Anpassung des Düsenwerkstoffes an die Erfordernisse des Werkstücks.The interchangeability of the nozzles according to claim 8 favors an adaptation of the inner diameter of the nozzle to the diameter of the workpieces to be straightened and furthermore permits simple adaptation of the nozzle material to the requirements of the workpiece.

In Fig. 1 ist eine Sechsrollenrichtmaschine gezeigt, die ein Maschinengestell, bestehend aus einem oberen Querhaupt 1 und einem unteren Ständer 2, aufweist, die durch Zuganker 3,4,5,6 miteinander verbunden sind. Zwischen dem Querhaupt 1 und dem Ständer 2 sind die 6 Richtrollen 7,8,9,10,11,12 angeordnet. Alle Richtrollen sind schräg zur Durchlaufrichtung 31 des Werkstücks 44 angestellt und haben über ihre Länge gesehen ein konkaves Profil. Alle Richtrollen werden in Rollenstühlen 13,14,15,16,17,18 getragen, die jeweils am oberen bzw. unteren Querhaupt befestigt sind. Alle Rollenstühle können entsprechend den Pfeilen 28,29,30 um eine senkrechte Achse geschwenkt werden. Alle Richtrollen sind drehangetrieben, wie das anhand der in Fig.2 gezeigten Richtrollen 8,10 und 12 mit Hilfe der Gelenkwellen 36,37,38 gezeigt ist. Die Motoren selbst sind aus darstellerischen Gründen weggelassen. Die 2 Zuganker 4 und 5 an der Peripherie des Maschinengestells werden durch eine Traverse 19 verbunden, die durch Klemmstücke 20,21 an den Zugankern befestigt wird. Die Klemmstücke und die Traverse werden durch Schrauben 22,23 mit den Zugankern verspannt.1 shows a six-roller straightening machine which has a machine frame consisting of an upper crosshead 1 and a lower stand 2, which are connected to one another by tie rods 3, 4, 5, 6. The 6 straightening rollers 7, 8, 9, 10, 11, 12 are arranged between the crosshead 1 and the stand 2. All straightening rollers are positioned at an angle to the direction of passage 31 of the workpiece 44 and have a concave profile over their length. All straightening rolls are carried in wheelchairs 13, 14, 15, 16, 17, 18, which are each attached to the upper and lower crosshead. All wheelchairs can be swiveled around a vertical axis in accordance with arrows 28, 29, 30. All straightening rollers are driven in rotation, as is shown by means of the straightening rollers 8, 10 and 12 shown in FIG. 2 with the aid of the cardan shafts 36, 37, 38. The motors themselves have been omitted for the sake of illustration. The 2 tie rods 4 and 5 on the periphery of the machine frame are connected by a cross member 19 which is fastened to the tie rods by clamping pieces 20, 21. The clamping pieces and the traverse are clamped to the tie rods by screws 22, 23.

Von der Traverse 19 kragen zwei Tragarme 26,27 in den Bereich der Richtrollen hinein. An ihren Enden tragen sie Führungsdüsen 34, 35. Die Führungsdüsen weisen je einen Einlauftrichter 39,40 auf. Die Führungsdüsen schließen die Lücken zwischen aufeinanderfolgenden Richtrollen 8,10/10,12. Beide Führungsdüsen sind gleichartig. Der Düsentrichter 40 schließt an die Austrittsstelle 42 des Werkstücks aus der Richtrollengruppe 7,8 an. Das Ende der Düse 35 reicht bis an die Einlaufstelle 43 des Werkstücks 44 zwischen die Rollen 9 und 10. Die Führungsdüse 35 überbrückt den Freiraum 41 zwischen der Gruppe der Rollen 7 und 8 einerseits und der Gruppe der Rollen 9 und 10 andererseits.Two support arms 26, 27 protrude from the traverse 19 into the area of the straightening rollers. They have guide nozzles 34, 35 at their ends. The guide nozzles each have an inlet funnel 39, 40. The guide nozzles close the gaps between successive straightening rollers 8, 10/10, 12. Both guide nozzles are the same. The nozzle 40 includes hopper to the exit point 42 of the workpiece from the Richtrollengru p pe to 7.8. The end of the nozzle 35 extends to the entry point 43 of the workpiece 44 between the rollers 9 and 10. The guide nozzle 35 bridges the space 41 between the group of rollers 7 and 8 on the one hand and the group of rollers 9 and 10 on the other.

Die Düsen 34,35 sind auswechselbar. Sie sind an den Tragarmen 26,27 mit je einer Schraube 45 in einer Bohrung 46 der Tragarme befestigt.The nozzles 34, 35 are interchangeable. They are fastened to the support arms 26, 27 with a screw 45 in a bore 46 of the support arms.

Von der Traverse 19 her ragen die Tragarme 26,27 mit den Führungsdüsen 34,35 an ihren freien Enden seitlich in die Freiräume axial zwischen die Richtrollen 7 bis 12. Die Tragarme selbst sind an der Traverse 19 mit Schrauben 24,25 befestigt.The support arms 26, 27 with the guide nozzles 34, 35 protrude laterally from the cross member 19 at their free ends into the free spaces axially between the straightening rollers 7 to 12. The support arms themselves are fastened to the cross member 19 with screws 24, 25.

Die Düsen 34,35 sind höhenverstellbar. Die Höhenverstellung erfolgt gemäß den Pfeilen 32,33 durch eine Verschiebung der Traverse 19 an den Zugankern 4,5. Die Höhenverstellung der Düsen kann von der Peripherie der Richtmaschine her erfolgen und ist deshalb besonders gut zugänglich. Dazu müssen die Schrauben 22,23 gelöst und in der neuen Stellung wieder angezogen werden. Die Höhenverstellung der Traverse 19 und damit verbunden der Führungsdüsen 34,35 kommt zur Anwendung, wenn die Biegelinie des Werkstücks in der Richtmaschine verändert wird, oder wenn aus Verschleißgründen die Walzen nachgeschliffen wurden und somit die Maschinenmitte abgesenkt wurde.The height of the nozzles 34, 35 is adjustable. The height is adjusted according to arrows 32, 33 by moving the cross member 19 on the tie rods 4, 5. The height of the nozzles can be adjusted from the periphery of the leveler and is therefore particularly accessible. To do this, the screws 22, 23 must be loosened and tightened again in the new position. The height adjustment of the traverse 19 and the associated guide nozzles 34, 35 are used when the bending line of the workpiece is changed in the straightening machine or when the rollers have been reground for reasons of wear and the center of the machine has thus been lowered.
