Abstract
Description
Die Erfindung betrifft ein Verfahren zum Entfernen von an einer Werkstückoberfläche anhaftenden Schweißperlen.The The invention relates to a method for removing adhering to a workpiece surface Beads of sweat.
Aus
der
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren anzugeben, bei dem Schweißperlen an einer Werkstückoberfläche im Bereich von Schweißnähten zwischen Abgasleitungen und Verbindungsflanschen einer Brennkraftmaschine auch an Stellen mit Hinterschnitt in einfacher Weise schadensfrei entfernt werden können.Of the Invention is based on the object of specifying a method at the welding beads on a workpiece surface in the area of welds between Exhaust pipes and connecting flanges of an internal combustion engine even in places with undercut in a simple way damage-free can be removed.
Die Aufgabe ist erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst.The Task is inventively by the features of claim 1 solved.
Aufgrund der Flexibilität der Borsten der Bürste können in einfacher Weise auch Bereiche von Werkstückoberflächen reinigend erreicht werden, die Hinterschnitte aufweisen. Durch eine geeignete Wahl der Borsteneigenschaften der Bürste, wie Material, Dicke und/oder Länge der Borsten, kann deren Elastizität und dadurch der Anpressdruck auf die zu reinigende Stelle der Werkstückoberfläche optimal an die bestehenden Anforderungen angepasst werden, so dass die Schweißnaht und der Grundwerkstoff der Abgasleitung bei der Bürstbearbeitung nicht geschädigt werden. Trotz des pfleglichen Umgangs beim Bearbeitungsvorgang mit der Bürste kann die Beaufschlagung so eingestellt werden, dass sich sämtliche im Motorbetrieb lösbaren Schweißperlen bzw. Schweißspritzer ablösen. Die abgelösten Schweißperlen bleiben entweder in den Borsten der Bürste hängen, wonach diese gereinigt werden muss, oder/und sie fallen in die Abgasleitung, aus der sie dann in einem abschließenden Arbeitsgang mittels Druckluft ausgeblasen oder mittels einer Flüssigkeit ausgeschwemmt werden.by virtue of the flexibility the bristles of the brush can in a simple manner also areas of workpiece surfaces can be achieved cleaning, have the undercuts. By a suitable choice of bristle properties the brush, such as material, thickness and / or length the bristles, their elasticity and thereby the contact pressure on the point to be cleaned of the workpiece surface optimally to the existing Requirements are adjusted so that the weld and the base material of the exhaust pipe is not damaged during brushing. Despite the careful handling of the machining process with the brush can the admission be adjusted so that all in the Motor operation detachable beads of sweat or spatter peel off. The detached ones beads of sweat either hang in the bristles of the brush, after which they are cleaned must be, or / and they fall into the exhaust pipe, from which they then in a final Operation blown out by means of compressed air or flushed out by means of a liquid become.
In einer besonders bevorzugten Weiterbildung der Erfindung nach Anspruch 2 erfolgt das Bürsten um die Drehachse der Bürste rotierend. Hierdurch wird erreicht, dass alle Borsten der Bürste in gleicher Stärke bei der Beaufschlagung der zu reinigenden Werkstückoberflächen abgenutzt werden, so dass ein gleichmäßiger Verschleiß der Bürste erreicht wird, aufgrund dessen die Bürste länger einsetzbar ist.In a particularly preferred embodiment of the invention according to claim 2, the brushing takes place around the axis of rotation of the brush rotary. This ensures that all bristles of the brush in the same Strength be worn in the application of the workpiece surfaces to be cleaned, so that achieved a uniform wear of the brush becomes, due to which the brush longer can be used.
In einer weiteren, besonders bevorzugten Weiterbildung der Erfindung nach Anspruch 3 wird das Bürsten maschinell betrieben, wobei insbesondere Roboter zum Einsatz kommen. Hierdurch wird eine gleichmäßige Bearbeitung der Werkstückoberflächen erzielt, was zu einer hohen Wiederholgenauigkeit beim Reinigen mehrerer gleichgestalteter Werkstückoberflächen führt. Hierdurch werden unterschiedliche Arbeitsergebnisse vermieden, die aus einer manuellen Betätigung durch Werker auftreten, da deren Bearbeitung von der Tagesform und der Leibeskraft abhängig ist.In a further, particularly preferred embodiment of the invention according to claim 3, the brushing operated by machines, in particular robots are used. This will result in uniform processing achieved the workpiece surfaces, resulting in a high repeat accuracy when cleaning several identically designed workpiece surfaces. hereby Different work results are avoided, resulting from a manual operation occur by workers, since their processing of the day form and dependent on physical strength is.
In einer weiteren, besonders bevorzugten Ausgestaltung der Erfindung nach Anspruch 4 wird die Kontur der Werkstückoberfläche mit der Bürste abgefahren. Hierdurch sind beliebige, insbesondere ovale Konturen der Werkstückoberfläche in gleicher Weise von der Beaufschlagung der Bürste erfassbar, wodurch besonders gewährleistet wird, dass alle Schweißspritzer bzw. Schweißperlen von der Bürstbearbeitung erreicht und entfernt werden. Toleranzabweichungen der zu reinigenden Oberflächen spielen beispielsweise bei einer Kreissymmetrie der Oberfläche dann keine Rolle mehr.In a further, particularly preferred embodiment of the invention According to claim 4, the contour of the workpiece surface is traveled with the brush. As a result, any, in particular oval contours of the workpiece surface in the same way from the application of the brush detectable, which ensures especially will that all spatter or welding beads from brushing be reached and removed. Tolerance deviations of the to be cleaned surfaces play for example in a circular symmetry of the surface then no longer matter.
In einer weiteren, besonders bevorzugten Weiterbildung der Erfindung nach Anspruch 5 wird die Werkstückoberfläche vor dem Bürstvorgang gekühlt. Hierdurch wird der Verschleiß der Bürste ganz erheblich herabgesetzt, was dieser eine besonders lange Haltbarkeit verleiht. Die Kühlung wird vorzugsweise mittels Druckluft oder Inertgasen durchgeführt, wodurch eine Korrosion der heißen Oberflächen verhindert wird. Des Weiteren ist darauf zu achten, dass die Werkstückoberflächen gleichmäßig heruntergekühlt werden, da sonst die Schweißnaht versprödet und dadurch, insbesondere im Motorbetrieb, schadhaft wird. Dies kann dazu führen, dass die Schweißnaht versagt und dadurch die Funktion des gesamten Abgasstranges außer Kraft gesetzt wird.In a further, particularly preferred embodiment of the invention according to claim 5, the workpiece surface is cooled before the brushing operation. This will completely erode the brush significantly reduced, which gives this a particularly long shelf life. The cooling is preferably carried out by means of compressed air or inert gases, whereby corrosion of the hot surfaces is prevented. Furthermore, care must be taken to ensure that the workpiece surfaces are cooled evenly, otherwise the weld becomes brittle and thus becomes defective, in particular during engine operation. This can cause the weld to fail and thereby override the function of the entire exhaust line.
