Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Durchtrennen eines zylindrischen Werkstücks mit einer Auflage zur Lagerung des Werkstücks und einer an einer Halterung befestigten, im Abstand zur Auflage veränderlichen Kreissäge mit einem auf einer drehbar angetriebenen Achse angeordneten Sägeblatt.The The invention relates to a device for cutting through a cylindrical workpiece with a support for supporting the workpiece and one on a holder attached, in the distance to the support variable circular saw with a arranged on a rotatably driven axle saw blade.
Eine derartige Vorrichtung, die beispielsweise als Kappsäge ausgebildet sein kann, wird regelmäßig zum Durchtrennen von zylindrischen Werkstücken, z. B. Rohren, verwendet. Das Rohr wird hierzu auf einer Auflage gelagert, die Kappsäge abgesenkt, so dass sie in das Rohr schneidet und das Rohr ggf. beim Schneidvorgang um seine Langsachse gedreht, um einen glatten, zur Längsachse des Rohres orthogonalen Schnitt zu erhalten.A Such device, for example, designed as a chop saw can be regularly added to Cutting through cylindrical workpieces, z. As pipes used. The tube is stored on a support, the chop saw lowered, so that it cuts into the pipe and possibly the pipe during the cutting process rotated around its longitudinal axis, to a smooth, to the longitudinal axis of the pipe to obtain orthogonal section.
Um fachgerechte Steckverbindungen zwischen mehreren Rohren, beispielsweise Kunststoffgranulatrohren, zu erhalten, ist es zusätzlich notwendig, die Stirnseite des durchtrennten Rohres auf seiner Außenseite anzufasen. Zu einer normgerechten Herstellung einer Steckverbindung sollte die fase um 15° von der Längsachse des Rohres abweichen.Around professional connections between several pipes, for example Plastic granulate pipes, it is additionally necessary the front of the severed pipe on its outside chamfer. To a standardized production of a connector should the chamfer at 15 ° of the longitudinal axis deviate from the pipe.
In der Praxis stellt sich dieser Vorgang jedoch als recht aufwändig dar, sodass abweichend von der oben stehenden Darstellung oftmals auf einen Winkelschleifer zurückgegriffen wird, um das Rohr zu durchschneiden, um es beispielsweise von einer Rohrmuffe zu trennen, und anzufasen. Dieses regelmäßig von Hand durchgeführte Verfahren entspricht jedoch keinesfalls der normgerechten Herstellung einer Steckverbindung. Insbesondere zeigt sich dieses in fehlerhaft hergestellten Rohrsteckverbindungen, die in einem mangelhaften und Umwelteinflüssen ausgesetzten Rohrsystem resultieren.In In practice, however, this process is quite complex, so deviating from the above illustration often on used an angle grinder is to cut through the pipe, for example, from a Separate pipe socket and to be chamfered. This regularly from Hand carried out However, the method does not comply with the standard production a plug connection. In particular, this shows in faulty produced pipe connectors, which are in a deficient and environmental influences exposed piping system result.
Aufgabe der Erfindung ist es daher, eine Vorrichtung zu schaffen, mit der zylindrische Werkstücke zersägt und angefast, insbesondere Rohre für eine normgerechte Steckverbindung hergestellt werden können, um ein gegen Umwelteinflüsse abgeschottetes Rohrsystem zu schaffen.task The invention is therefore to provide a device with the sawed and chamfered cylindrical workpieces, especially pipes for a standardized plug connection can be made to against environmental influences To create a sealed pipe system.
Die Aufgabe wird durch die Vorrichtung mit den Merkmalen von Anspruch 1 gelöst. Die Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung wieder.The The object is achieved by the device having the features of claim 1 solved. The dependent claims give advantageous embodiments of the invention again.
Grundgedanke der Erfindung ist es, das Grundprinzip einer Kappsäge dahingehend weiterzubilden, dass ein dem Sägeblatt benachbart angeordnetes Fräswerkzeug zum Anfasen einer Stirnseite des von der Säge durchtrennten zylindrischen Werkstücks vorgesehen ist, wobei der Durchmesser des Fräswerkzeugs geringer ist als der Durchmesser des Sägeblatts. Dabei ist auch erfindungsgemäß vorgesehen, dass der veränderliche Abstand der Kreissäge zum Werkstück durch einen Abstandhalter begrenzt ist, so dass die erfindungsgemäße Sage nur bis auf den Arbeitsbereich des Fräswerkzeugs im Verhältnis zum zu durchtrennenden Werkstück absenkbar ist.basic idea The invention is the basic principle of a chop saw to that effect educate that one the saw blade adjacent arranged milling tool for chamfering a front side of the cut by the saw cylindrical workpiece is provided, wherein the diameter of the milling tool is less than the diameter of the saw blade. It is also provided according to the invention that the changeable Distance of the circular saw to the workpiece is limited by a spacer, so that the legend according to the invention only up to the working area of the milling tool in relation to to be cut workpiece is lowerable.
Die Erfindung wird im Folgenden anhand von Zeichnungen näher erläutert. Dabei wird insbesondere auf die Verwendung der erfindungsgemäßen Vorrichtung beim Durchtrennen und Anfasen von Rohren zur Herstellung einer Steckverbindung eingegangen. Es versteht sich jedoch, dass die erfindungsgemäße Vorrichtung auch für andere zylindrische Werkstücke verwendet werden kann, ohne dass eine Steckverbindung herzustellen ist. In den Zeichnungen zeigen:The The invention is explained in more detail below with reference to drawings. there is in particular the use of the device according to the invention during cutting and chamfering of pipes for the production of a plug connection received. It is understood, however, that the device according to the invention also for other cylindrical workpieces can be used without making a plug connection is. In the drawings show:

Die erfindungsgemäße Vorrichtung ermöglicht die standfeste, genaue und schnelle Trennung von Kunststoffrohren auf die gewünschte Länge, bei gleichzeitiger Herstellung der benötigten Fase am Rohrende.The inventive device allows the stable, accurate and fast separation of plastic pipes to the desired Length, with simultaneous production of the required bevel at the pipe end.
Die Rohraufnahme gewährleistet ein genau orthogonales Trennen des Rohres und durch das Drehen des Rohres beim Schneidvorgang auf den Kunststoffrollen wird das Rohr umlaufend sauber getrennt und gleichzeitig gefast. Durch die Begrenzungsmöglichkeit der Eintauchtiefe wird die Fase fachgerecht vom jeweiligen Rohrdurchmesser hergestellt. Allzu tiefes Eintauchen wird verhindert.The Tube intake guaranteed a precisely orthogonal separation of the tube and by turning the Pipe during the cutting process on the plastic rollers becomes the pipe completely clean and at the same time fasted. Due to the limitation possibility the immersion depth, the chamfer is professional from the respective pipe diameter produced. Too deep immersion is prevented.
