Abstract

The power saws used nowadays have saw chains which are continuously lubricated and have to be sharpened, often with considerable effort. The invention of the tubular wood-working tool means that environmentally polluting chain lubrication is no longer required, sharpening of the teeth is made significantly easier and, in addition, even curved cuts can be made instead of only straight cuts. The tubular wood-working tool 1 has outwardly protruding cutting teeth 3. The tubular wood-working tool 1 is set in rotation by the drive motor 2, whereby the cutting teeth 3 cut out chips from the material to be cut, for example wood. Some of these chips pass through the opening 5, located under the cutting tooth, into the interior of the tube and are transported pneumatically or mechanically to the end of the tube and then into the open. <IMAGE>

AT 397 486 B Rohrförmiges Holzbearbeitunpswerkzeug Zum Schneiden von Holz und anderen Werkstoffen werden heute Motorsägen verwendet, die von Elektro-oder Verbrennungskraftmotoren angetrieben werden. Zum Sägen selbst wird eine Sägekette verwendet, die - laufend Kettenöl zur Schmierung benötigt, was die Umwelt verschmutzt, - kompliziert geschärft werden muß und - nur gerade Schnitte erlaubt Andere, stabförmige Werkzeuge weisen für den Einsatz als Motorsägeblatt ein höheres Gewicht auf und können auch die Späne nur schwierig abfÜhren. Mit einem rohrförmigen Holzbearbeitungswerkzeug als Schneidorgan können obige Nachteile vermieden werden. Die Erfindung sieht vor, daß das rohrförmige Holzbearbeitungswerkzeug (1) auswechselbar mit einem Sägemotor (2) verbunden ist Das rohrförmige Holzbearbeitungswerkzeug ist innen hohl und weist mehrere, am Außenumfang des Rohres radial und achsial versetzte, nach außen ragende Schneidzähne (3) auf. Diese sind in achsialer Richtung fluchtend angebracht Unmittelbar neben den Schneidzähnen befinden sich Ausnehmungen (5). Mit einem Schärfstein (4) können durch achsiales Verschieben auf dem rohrförmigen Holzbearbeitungswerkzeug alle Schneidzähne geschärft werden (Fig.). Der Sägemotor (2) dreht das rohrförmige Holzbearbeitungswerkzeug radial. Es wird gegen den zu schneidenden Gegenstand geführt, wobei jeder Schneidzahn einen Span aus dem Gegenstand herausschneidet Meistens wird der Span ins Rohrinnere gelangen und von dort durch eine Förderspirale, durch Druckluft oder andere Vorrichtungen an das Rohrende und dann ins Freie befördert Durch die Rohrform können nicht nur gerade sondern auch kurvenförmige Schnitte ausgeführt werden. PATENTANSPRÜCHE 1. Zylinderförmiges, mit Schneiden versehenes Holzbearbeitungswerkzeug zur Verwendung in Handmotorsägen, dadurch gekennzeichnet, daß der Zylinder als drehbar antreibbares Rohr (1) ausgebildet ist und bogenförmig über den Zylindermantel sich erhebende Schneiden (3) und in Drehrichtung vor jeder Schneide das Rohr durchbrechende Ausnehmungen (5) sowie Vorrichtungen zum mechanischen oder pneumatischen Austragen von in das Rohrinnere gelangenden Spänen aus diesem vorgesehen sind.AT 397 486 B Tubular woodworking tool Chainsaws that are driven by electric or internal combustion engines are used today for cutting wood and other materials. For the sawing itself, a saw chain is used that - continuously needs chain oil for lubrication, which pollutes the environment, - has to be sharpened in a complicated manner and - only straight cuts are allowed It is difficult to remove chips. With a tubular woodworking tool as a cutting element, the above disadvantages can be avoided. The invention provides that the tubular woodworking tool (1) is interchangeably connected to a saw motor (2). The tubular woodworking tool is hollow on the inside and has a plurality of cutting teeth (3) projecting radially and axially offset on the outer circumference of the pipe. These are aligned in the axial direction. There are recesses (5) immediately next to the cutting teeth. With a sharpening stone (4), all cutting teeth can be sharpened by moving them axially on the tubular woodworking tool (Fig.). The saw motor (2) rotates the tubular woodworking tool radially. It is guided against the object to be cut, with each cutting tooth cutting a chip out of the object.Most of the time the chip will get into the pipe and from there through a conveyor spiral, compressed air or other devices to the pipe end and then be transported outdoors only straight but also curved cuts can be made. PATENT CLAIMS 1. Cylindrical woodworking tool with cutting edges for use in hand-held power saws, characterized in that the cylinder is designed as a rotatably drivable tube (1) and blades (3) rising in an arc over the cylinder jacket and recesses breaking through the tube in front of each cutting edge in the direction of rotation (5) and devices for mechanical or pneumatic discharge of chips entering the pipe interior are provided. 2. Rohrförmiges Holzbearbeitungswerkzeug nach Anspruch 1, dadurch gekennzeichnet, daß die Schneiden (3) achsial fluchtend angebracht sind, sodaß sie durch achsiales Hin- und Herschieben eines Schärfsteins (4) geschärft werden können. Hiezu 1 Blatt Zeichnung -2-2. A tubular woodworking tool according to claim 1, characterized in that the cutting edges (3) are axially aligned so that they can be sharpened by axially pushing a sharpening stone (4) back and forth. For this 1 sheet drawing -2-
