Abstract
Description
Die Erfindung betrifft ein Verfahren zum Korrigieren der Position eines Bearbeitungswerkzeugs für die allgemeine Bearbeitung von zylindrischen Rohren die während der Bearbeitung um ihre horizontal liegende Achse gedreht (rotiert) werden.The The invention relates to a method for correcting the position of a Editing tool for the general processing of cylindrical pipes during the Machining rotated around its horizontal axis (rotated) become.
Zylindrische Rohre werden ab gewissen Durchmessern aus gewalzten Blechen die nach dem Walzen zumeist durch ein Schweißverfahren am Umfang geschlossen wurden, hergestellt. Dabei gibt es unterschiedliche Rohrtypen. Hierbei sind insbesondere die mit Längs- oder Spiralnähten geschweißte Rohre zu unterscheiden. Durch die stets nur begrenzte Genauigkeit bei der Herstellung dieser Rohre, kommt es zu Unrundheiten, Krümmungen, oder Abweichungen im Durchmesser also z.B. Konizitäten, Tonnenform, u.s.w.. Diese Formfehler verursachen beim Rotieren Relativbewegungen im Bezug auf die, das Rohr haltenden oder tragenden Vorrichtungen. Dadurch kommt es beispielsweise bei einem Rohr mit einem Außendurchmesser von z.B. einem Meter und einer Länge von z.B. 10 Metern ohne weiteres zu einer Längsverschiebung von 5 mm, wenn das Rohr einmal um 360° gedreht wird.cylindrical Pipes are from certain diameters of rolled sheets the after rolling usually closed by a welding process on the circumference have been produced. There are different tube types. in this connection especially those with longitudinal or spiral seams welded pipes to distinguish. Due to the always limited accuracy at the production of these pipes, there are discontinuities, curvatures, or deviations in diameter, e.g. Conicities, barrel shape, u.s.w .. These shape errors cause relative movements during rotation with respect to the tube holding or carrying devices. As a result, for example, a tube with an outer diameter from e.g. a meter and a length from e.g. 10 meters readily to a longitudinal displacement of 5 mm, if the Once turned 360 ° becomes.
Das hier vorgeschlagene Verfahren zur Korrektur ist daher nötig, wenn es insbesondere bei schweren Rohren, bei der Rotation zu einer unzulässig großen Längsbewegung des Rohrs kommt, denn die beiden gängigsten Verfahren, Einspannen in einem Drehfutter oder Auflegen auf einer Rollendrehvorrichtung, sind beispielsweise bei über 1000 kg schweren Rohren nicht in der Lage die durch Walkbewegungen, Unrundheiten, Oberflächenfehler, u.s.w. ausgelösten Längsbewegungen vollständig zu unterbinden.The Proposed correction procedures are therefore necessary when especially in the case of heavy tubes, during rotation to an inadmissibly large longitudinal movement the tube comes, because the two most common methods, clamping in a lathe chuck or laying on a roller turning device, are for example over 1000 kg heavy pipes unable by the Walk movements, Non-circularities, surface defects, etc. triggered longitudinal movements Completely to prevent.
Störend wirkt die beschriebene Längsbewegung immer dann wenn an dem Rohr eine exakte Bearbeitung, mit Hilfe eines frei geführten Bearbeitungswerkzeugs vorgenommen werden soll. Frei geführt bedeutet hierbei, dass das Bearbeitungswerkzeug nicht am Werkstück sondern an einem seperaten Führungssystem oder Halter, befestigt ist. Dies kann z.B. die Bearbeitung mit Hilfe eines Trennschneideverfahrens wie z.B. dem Autogenschneiden, dem Plasmaschneiden, oder dem Laserschneiden sein. Ebenso kann es auch das Beschriften oder Markieren der Oberfläche mit geeigneten Werkzeugen sein. Bearbeitungswerkzeuge sind hierbei im weitestens Sinne Gerätschaften mit deren Hilfe eine Bearbeitung am Rohr ausgeführt werden kann.Disturbing acts the described longitudinal movement always when an exact processing on the pipe, with the help of a free guided Machining tool to be made. Free guided means Here, that the machining tool not on the workpiece but on a separate guidance system or holder, is attached. This can e.g. editing with help a separating cutting method such as e.g. the oxyacetylene cutting, the Plasma cutting, or laser cutting. So can it marking or marking the surface with suitable tools be. Machining tools are in the widest sense equipment with the help of a machining on the pipe can be performed.
Verschiebt sich das Rohr nun während des Arbeitsvorgangs in undefinierter Weise, ist es nicht mehr möglich den gewünschten Prozess mit hoher Genauigkeit auszuführen. So ist es z.B. nicht möglich ein Rohr das auf einer Drehvorrichtung liegt exakt gerade abzuschneiden, ohne dass nicht zumindest ein kleiner Versatz zwischen Beginn und Ende der Schneidfuge entsteht.moves the tube now while of the work process in an undefined way, it is no longer possible the desired Process with high accuracy. So it is e.g. Not possible Pipe that is lying on a turning device cut exactly straight, without at least a small offset between the beginning and the end End of the kerf is formed.
Aufgabetask
Der Erfindung liegt die Aufgabe zugrunde, den Fehler, der dadurch entsteht dass ein Rohr undefinierte Relativbewegungen im Bezug zu einem Bearbeitungswerkzeug ausführt, auszugleichen.Of the Invention is based on the object, the error that arises that a pipe undefined relative movements in relation to a machining tool executing, compensate.
Lösungsolution
Ausgehend von den bestehenden Verfahren zum Bearbeiten von Rohren wird nach der Erfindung vorgeschlagen, dem Bearbeitungswerkzeug eine zusätzliche Bewegung (Versatz oder Offset) aufzuprägen, die der störenden Bewegung des Rohrs mit hoher Genauigkeit folgt. Dieses wird durch einen fest montierten Sensor ermöglicht der den Abstand einer Platte misst die mittig im Rohrende fixiert ist. Durch eine geeignete Hilfsvorrichtung wird die besagte Platte im Rohrende fixiert. Die Platte wird dabei so ausgerichtet, dass ihre Ebene bei der Rotation des Rohrs nur eine kleine Taumelbewegung ausführt. Der fest montierte Sensor erfasst nun den Abstand zu dem Punkt der Platte, der nahe am Rotationszentrum des Rohrs liegt. Entfernt sich die Platte und damit das Rohr vom Sensor, oder nähert es sich an den Sensor an, so wird diese Wegänderung mit Hilfe einer Steuerung, als ein Versatz der Bewegung des Wekzeugs so hinzu gefügt, dass zwischen dem Rohr und dem Bearbeitungswerkzeug keine störende seitliche Verschiebung mehr auftritt.outgoing Of the existing methods for machining pipes is after proposed the invention, the machining tool an additional To impose motion (offset or offset), the disturbing movement follows the pipe with high accuracy. This is made by a firmly mounted Sensor allows which measures the distance of a plate which is fixed in the center of the pipe end is. By a suitable auxiliary device, the said plate fixed in the pipe end. The plate is aligned so that their plane during the rotation of the tube only a small tumbling motion performs. The fixed sensor now detects the distance to the point of the Plate lying near the center of rotation of the tube. Removes itself the plate and thus the tube from the sensor, or it approximates to the sensor, this is the way change by means of a controller, as an offset of the movement of the tool so added, that between the pipe and the machining tool no disturbing lateral Shift more occurs.
Beim Einsatz des vorgeschlagenen Verfahrens kann je nach Genauigkeit des Sensors und der nachfolgenden Steuerung eine entsprechende hohe Genauigkeit der gewünschten Bearbeitungskontur erreicht werden.At the Use of the proposed method may vary depending on accuracy the sensor and the subsequent control a corresponding high accuracy the desired Machining contour can be achieved.

Somit ist die Aufgabe der Erfindung gelöst, da nun unabhängig von allen sonstigen Bewegungen des Rohrs und z.B. des Bearbeitungswerkzeugs, die Posititon des Bearbeitungswerkzeugs in Längsrichtung zum Rohr stets der gewünschten und vorgegebenen Position entspricht.Consequently the object of the invention is solved, since now independent of all other movements of the tube and e.g. the machining tool, the position of the machining tool in the longitudinal direction of the pipe always the desired and predetermined position corresponds.
