Description

Die Erfindung bezieht sich auf eine vorzugsweise hydraulisch oder pneumatisch wirkende Richtmaschine mit einer Aufnahmevorrichtung für ein zu richtendes längserstrecktes Werkstück, wie Voll-, Hohlprofil oder Rohr, und einer Anordnung von Richtwerkzeugen mit Richtzylinder und daran angebrachtem Richtstempel.The invention relates to a preferably hydraulically or pneumatically acting straightening machine with a receiving device for an elongated workpiece to be straightened, such as solid, hollow profile or tube, and an array of straightening tools with straightening cylinder and straightening die attached thereto.

Die DE 94 01 813 U1 , der die Basis für den Oberbegriff des Anspruchs 1 bildet, zeigt eine Richtmaschine für längserstreckte Werkstocke, mit der ein Längsrichten durch Geradebiegen des Werkstückes erfolgt. Hierbei sind zwischen zwei entlang der Längsachse des Werkstückes versetzten seitlichen Anschlägen verstellbare Biegewerkzeuge angeordnet, wobei mehrere Biegewerkzeuge axial ortsgleich, in Umfangsrichtung versetzt, vorgesehen sind, die jeweils mit zugeordneten, axial versetzen Anlageflächen zum Geradebiegen des Werkstücks zusammenarbeiten.The DE 94 01 813 U1 , which forms the basis for the preamble of claim 1, shows a straightening machine for elongated work sticks, with which a longitudinal straightening is done by straight bending of the workpiece. In this case, adjustable bending tools are arranged between two offset along the longitudinal axis of the workpiece lateral stops, wherein a plurality of bending tools axially spatially offset in the circumferential direction, are provided which cooperate with associated axially offset contact surfaces for straight bending of the workpiece.

Auch die FR 737.123 A zeigt eine Längsrichtmaschine, wobei die langgestreckten Werkzeuge im warmen, insbesondere rot glühenden Zustand verformt werden. Hierbei liegen sich rechenartige Biegewerkzeuge gegenüber, wobei backenartigen Abschnitten auf der einen Seite des Werkstückes in Querrichtung zu dessen Längsachse Freiräume gegenüberliegen.Also the FR 737.123 A shows a longitudinal straightening machine, wherein the elongated tools are deformed in the warm, especially red glowing state. In this case, computational bending tools lie opposite each other, wherein jaw-like sections on one side of the workpiece in the transverse direction to the longitudinal axis opposite free spaces.

Eine weitere Richtpresse ist in der AT-PS 255 864 angegeben. Ein längserstrecktes Werkstück, insbesondere schienen-, stangen- oder rohrförmigen Materials, wird auf einem Führungsbett als Aufnahmevorrichtung aufgelegt und kann darauf verschoben werden, um mittels Richtwerkzeugen, die einen Richtstempel und zwei Widerlager umfassen, eine Biegung des Werkzeugs im für die Ausrichtung erforderlichen Ausmaß vorzunehmen. Dabei wird die Durchbiegung des Materials mittels eines vorstehenden Begrenzungsglieds begrenzt. Eine Schwierigkeit, die bei derartigen Richtpressen auftritt, ist eine mangelnde Richtgenauigkeit mit flexiblen Richtmöglichkeiten und eine mangelnde Richtgeschwindigkeit.Another straightening press is in the AT-PS 255 864 specified. An elongated workpiece, in particular rail, rod or tubular material is placed on a guide bed as a receiving device and can be moved thereon to make by means of straightening tools, which include a straightening and two abutments, a bending of the tool in the alignment required extent , In this case, the deflection of the material is limited by means of a protruding limiting member. One difficulty encountered with such straightening presses is a lack of straightening accuracy with flexible straightening capabilities and a lack of straightening speed.

Weitere ähnliche Richtpressen sind in der AT-PS 348 303 und der CH 647 332 A5 gezeigt. In der US 2004/0050135 A1 ist ein Richtwerkzeug mit zwei sich gegenüberliegenden Presskörpern und darin ausgebildeten Halbkanälen gezeigt.Other similar straightening presses are in the AT-PS 348 303 and the CH 647 332 A5 shown. In the US 2004/0050135 A1 is shown a straightening tool with two opposing compacts and formed therein half-channels.

Die DD 220 518 A1 zeigt eine Richtmaschine zum Richten von langen Profilstählen, mit der die Richtleistung der Presse erhöht werden soll und konkave und konvexe Verbiegungen des Richtmaterials beseitigt werden sollen, ohne dass das Richtmaterial gewendet oder gekantet werden muss. Hierzu sind an dem Maschinengestell zwei Richtzylinder vertikal für das Richten über die Abszisse der zu richtenden Schiene angeordnet und ein Richtzylinder horizontal für das Richten über die Ordinate. An den Kolbenstangen der Richtzylinder befinden sich druckseitige Richttraversen, denen feststehende Richttraversen gegenüberliegen. An den druckseitigen und feststehenden Richttraversen befinden sich als Gegenlager zwei Richtanschläge, die in Abhängigkeit von der gemessenen Verformungsrichtung in ihrem Abstand zueinander automatisch verstellbar so angeordnet sind, dass jeweils zwei auseinander geschobene Richtanschläge zwei zusammengeschobenen Richtanschlägen gegenüberstehen. Diese Richtpresse ist zum Richten axialer Verbiegungen ausgelegt.The DD 220 518 A1 shows a straightener for straightening long profiled steels, with which the straightening performance of the press should be increased and concave and convex bending of the straightening material to be eliminated without the straightening material must be turned or folded. For this purpose, two straightening cylinders are arranged vertically on the machine frame for straightening over the abscissa of the rail to be straightened and a straightening cylinder horizontally for straightening about the ordinate. On the piston rods of the straightening cylinder are pressure side straightening, which are opposite fixed straightening. On the pressure-side and stationary jibs are two abutment stops, which are automatically adjustable depending on the measured deformation direction in their distance from each other so arranged that two spaced-apart Richtanschläge face two pushed together Richtanschlägen. This straightening press is designed for straightening axial bends.

In der DE 103 54 654 B4 ist eine Vorrichtung zum Richten eines Rohres mit einer im Inneren des Rohres angeordneten Expandervorrichtung gezeigt, mit der eine radial nach außen gerichtete Kraft auf die Rohrwandung ausgeübt wird, wozu ein radial aufweitbarer Expanderkopf und mindestens ein Richtsattel vorgesehen sind, der an einer gewünschten Position entlang der Längsachse des Rohres positioniert werden kann. Hierbei ist ein in das Rohrinnere einführbarer stangen- oder rohrförmig ausgebildeter Holm vorgesehen, und der mindestens eine Richtsattel ist entlang der Längsachse des Holms verschiebbar und mittels Schrägen von der Längsachse des Holms radial nach außen drückbar.In the DE 103 54 654 B4 a device for straightening a tube is shown with an expander device disposed inside the tube, with which a radially outward force is exerted on the tube wall, for which purpose a radially expandable expander head and at least one straightening saddle are provided, which at a desired position along the Longitudinal axis of the tube can be positioned. Here, an insertable into the tube interior rod or tubular trained spar is provided, and the at least one saddle is adjustable along the longitudinal axis of the spar and slidable by means of bevels from the longitudinal axis of the spar radially outward.

Weitere Vorrichtungen zum Richten von Werkstoffen sind in der DE 23 63 297 B2 , der DE 600 07 065 T2 , der DE 197 06 622 C2 und der DE 20 2004 009 261 U1 gezeigt.Other devices for straightening materials are in the DE 23 63 297 B2 , of the DE 600 07 065 T2 , of the DE 197 06 622 C2 and the DE 20 2004 009 261 U1 shown.

Der Erfindung liegt die Aufgabe zugrunde, eine Richtmaschine der eingangs genannten Art bereitzustellen, mit der die Kontur eines längs erstreckten Werkzeugs mit hoher Genauigkeit und Richtgeschwindigkeit kalibriert werden kann.The invention has for its object to provide a straightening machine of the type mentioned, with the contour of an elongated tool with high accuracy and directional speed can be calibrated.

Diese Aufgabe wird mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with the features of claim 1.

Mit den in Umfangsrichtung versetzten und in axialer Richtung des längserstreckten Werkstücks, insbesondere Profils bzw. Rohres, ortsgleich angeordneten Richtzylindern mit jeweiligem Richtstempel kann die Umfangskontur schnell und genau gerichtet werden, beispielsweise durch Impandieren auf von Rohr zu Rohr gleichen Innendurchmesser oder gleichen Außendurchmesser.With the offset in the circumferential direction and in the axial direction of the elongate workpiece, in particular profile or tube, uniformly arranged straightening cylinders with respective straightening the peripheral contour can be quickly and accurately directed, for example by impanding on the same inner diameter or the same outer diameter from tube to tube.

Die Kalibrierung beispielsweise eines im Querschnitt runden oder ovalen Profils bzw. Rohres wird dabei dadurch begünstigt, dass die Richtstempel abschnittsweise entsprechend der Querschnittskontur der Werkstückoberfläche geformte Richtschalen tragen.The calibration of, for example, a profile or tube which is round or oval in cross-section is thereby facilitated by the directional punches carrying directional shells in sections corresponding to the cross-sectional contour of the workpiece surface.

Verbesserte Richtmöglichkeiten entlang des Umfangs ergeben sich dadurch, dass die Richtwerkzeuge mehr als zwei in Umfangsrichtung des Werkstückes versetzte Richtzylinder mit Richtstempel aufweisen.Improved straightening possibilities along the circumference result from the straightening tools having more than two straightening cylinders with straightening dies offset in the circumferential direction of the workpiece.

Zu einer genauen Justierung tragen die Maßnahmen bei, dass eine Steuerungs- oder Regelungsvorrichtung vorhanden ist, mittels deren die Richtzylinder gesteuert oder geregelt betätigbar sind.To a precise adjustment, the measures contribute that a control or regulating device is present, by means of which the straightening cylinders are controlled or regulated actuated.

Hierbei bestehen verschiedene Ausgestaltungsvarianten darin, dass die Betätigung der Richtzylinder in Abhängigkeit voneinander oder unabhängig voneinander erfolgt.In this case, various design variants exist in that the actuation of the straightening cylinder takes place as a function of one another or independently of one another.

Eine Ausgestaltungsvariante für ein schnelles Richten besteht darin, dass die Richtzylinder mit den Richtstempeln in Längsrichtung des Werkstückes paarweise axial versetzt sind.One design variant for a quick straightening is that the straightening cylinders are axially offset in pairs with the straightening dies in the longitudinal direction of the workpiece.

Eine genaue Kalibrierung wird vorteilhaft dadurch erreicht, dass vier in Umfangsrichtung um 90° gegeneinander versetzte Richtzylinder mit Richtstempel vorhanden sind.An accurate calibration is advantageously achieved in that four in the circumferential direction by 90 ° staggered straightening cylinder are available with straightening.

Weiterhin ist es möglich, mit zwei in Umfangsrichtung um 120° gegeneinander versetzten Richtzylindern mit Richtschalen und einer festen Richtschale ohne Richtzylinder die genaue Kalibrierung auszuführen.Furthermore, it is possible, with two circumferentially offset by 120 ° staggered directional cylinders with straightening cups and a fixed straightening shell without straightening perform the exact calibration.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnungen näher erläutert.The invention will be explained in more detail using an exemplary embodiment with reference to the drawings.

Die Fig. 1 zeigt schematisch die Anordnung von Werkzeugen einer Richtmaschine zum Rundrichten relativ zu einem Werkstück in axialer Ansicht, wobei ein Anschluss an eine Regelungsvorrichtung besteht.The Fig. 1 schematically shows the arrangement of tools of a straightening machine for Rundricht relative to a workpiece in axial view, wherein a connection to a control device consists.

Fig. 2 zeigt ein Ausführungsbeispiel einer Richtmaschine zum Rundrichten mit drei axial an gleicher Stelle, jedoch in Umfangsrichtung um 120° gegeneinander versetzten Richtstempeln 21 (Richtschalen), von denen eine fest und die beiden anderen mit jeweils zugeordneten Zylindern 20 wie bei dem Ausführungsbeispiel nach Fig. 1 verstellbar sind. Fig. 2 shows an embodiment of a straightening machine for Rundrichten with three axially at the same place, but circumferentially offset by 120 ° staggered Richtstempeln 21 (straightening shells), one of which fixed and the other two, each with associated cylinders 20 as in the embodiment according to Fig. 1 are adjustable.

Nach Fig. 1 wird ein längs erstrecktes Werkstück 1, vorliegend ein Rohr bzw. rundes Hohlprofil, auf einer nicht gezeigten Aufnahmevorrichtung im Bereich zwischen Richtwerkzeugen gelagert, die als wesentliche Teile einen jeweiligen Richtzylinder 20 mit daran über einen Träger 23 angeschlossenen, quer zur Längsachse des Werkstückes 1 verstellbaren Richtschalen 21 aufweisen. Die Richtschalen 1 können an den oder mit den Trägern 23 austauschbar an den Richtzylindern 20 angebracht sein. Die Richtschalen 21 sind auf ihrer dem Werkstück 1 zugekehrten Vorderseite entsprechend der Querschnittskontur des Werkstückes 1 gekrümmt und erstrecken sich über eine gewisse Länge in Längsrichtung des Werkstückes 1.To Fig. 1 is an elongated workpiece 1, in this case a tube or round hollow profile, mounted on a recording device, not shown, in the area between straightening tools, as essential parts a respective straightening cylinder 20 connected thereto via a carrier 23, transverse to the longitudinal axis of the workpiece 1 adjustable straightening shells 21 have. The straightening shells 1 can be attached to or with the carriers 23 exchangeably attached to the straightening cylinders 20. The straightening shells 21 are curved on their front side facing the workpiece 1 corresponding to the cross-sectional contour of the workpiece 1 and extend over a certain length in the longitudinal direction of the workpiece 1.

Die Verstellung des jeweiligen Trägers 23 mit der daran angebrachten Richtschale 21 erfolgt z.B. hydraulisch mittels einer an sich bekannten Kolben-Zylinder-Einheit entlang einer Verstellachse bzw. Regelachse 22 quer zur Längsachse des Werkstückes 1. Die Richtschalen 21 können einzeln für sich oder in Abhängigkeit voneinander verfahren werden, wobei die Betätigung gesteuert oder geregelt vorgenommen werden kann. Vorteilhaft für eine genaue Kalibrierung ist jedoch die Betätigung mit einer Regelungsvorrichtung 30, die in Abstimmung auf die Kontur des Werkstückes 1 mittels entsprechender Sensorik erfolgt und eine hohe Richtgenauigkeit bei hoher Richtgeschwindigkeit ermöglicht. Für die Sensorik kommen mechanische oder optische Ausrüstungen oder elektrische oder magnetische Messvorrichtungen in Betracht.The adjustment of the respective carrier 23 with the straightening bowl 21 attached thereto takes place e.g. hydraulically by means of a per se known piston-cylinder unit along an adjustment or control axis 22 transversely to the longitudinal axis of the workpiece 1. The straightening shells 21 can be moved individually or in dependence on each other, the operation can be controlled or controlled. Advantageous for accurate calibration, however, is the operation with a control device 30, which takes place in coordination with the contour of the workpiece 1 by means of appropriate sensors and enables a high leveling accuracy at high straightening speed. For the sensor, mechanical or optical equipment or electrical or magnetic measuring devices come into consideration.

Über die Regelachsen 22 können die Richtzylinder 20 mit den Richtschalen 21 das Rohr bis zu dessen z.B. kreisrunder Kontur richten. Bei Werkstücken 1 mit rundem Querschnitt erfolgt die Verstellung der Richtschalen 21 mittels der Richtzylinder 20 jeweils radial bezüglich des Werkstückes. Die Kalibrierung erfolgt bezüglich des Durchmessers und/oder der Ovalität. Die Werkstücke bzw. Profile können kalt oder warm (bis zur Normalisierungstemperatur) kalibriert werden. Auch ein Stauchen des Werkstoffes über die Streckgrenze hinaus ist möglich.About the control shafts 22, the straightening cylinder 20 can judge with the straightening shells 21, the pipe up to its example circular contour. For workpieces 1 with a round cross-section, the adjustment of the straightening shells 21 takes place by means of the straightening cylinder 20 in each case radially with respect to the workpiece. The calibration is done in terms of diameter and / or ovality. The workpieces or profiles can be calibrated cold or warm (up to the normalization temperature). It is also possible to upsize the material beyond the yield point.

Für die Steuerung oder Regelung ist in der Vorrichtung eine absolute Position vorgegeben oder vorgebbar. Eine vorteilhafte Ausbildung besteht darin, dass die Position aufgrund von Sensordaten der Sensorik vorgebbar bzw. berechenbar ist und auf Basis dieser Positionsdaten die Richtvorgänge steuerbar oder regelbar sind. Auch bei ungleichen oder uneinheitlichen Wandstärken von Rohren kann dabei ein Richten durch Impandieren stets auf gleichen Innendurchmesser oder alternativ auf gleichen Außendurchmesser vorgenommen werden.For the control or regulation in the device an absolute position is specified or predetermined. An advantageous embodiment consists in that the position can be predetermined or calculated on the basis of sensor data of the sensor system and the straightening processes can be controlled or regulated on the basis of this position data. Even with uneven or non-uniform wall thicknesses of pipes straightening by impanding can always be made on the same inner diameter or alternatively on the same outer diameter.

Aufgrund der mehrschaligen Segmente bzw. Richtschalen 21 wird in kurzer Zeit eine hohe Richtgenauigkeit erzielt, wobei örtliche Unrundheiten ausgeglichen werden. Dadurch lassen sich Rohre, Voll- und Hohlprofile mit hohen Toleranzanforderungen herstellen. Das Stauchen des Werkstoffes ermöglicht es, auch praktisch eine Nulltoleranz am Profilkörper zu gewährleisten. Weiterhin ist es auch möglich, mit dem angegebenen Aufbau die genannten Werkstücke mit den mehrschaligen Werkzeugen in andere als die Ausgangskontur umzuwandeln, z.B. von rund in eckig, wofür entsprechend geformte Richtschalen 21 angebracht werden.Due to the multi-layered segments or straightening shells 21 a high leveling accuracy is achieved in a short time, with local omissions are compensated. As a result, tubes, solid and hollow profiles can be produced with high tolerance requirements. The upsetting of the material makes it possible to ensure virtually zero tolerance on the profile body. Furthermore, it is also possible, with the specified construction, to convert the said workpieces with the multi-shell tools into other than the initial contour, e.g. from around in square, for which purpose shaped straightening dishes 21 are attached.
