Abstract
Description
Die Erfindung geht von einem Sägeblatt für Holz oder ähnliche Werk stoffe nach der Gattung des Hauptanspruchs aus. Bisher wiesen Säge blätter für motorisch angetriebene Stich- und Säbelsägen gerade Zahnreihen auf, wie z. B. aus der DE-OS 27 50 969 hervorgeht. Beim Arbeiten mit diesen Sägetypen ist eine gerade Zahlenreihe jedoch in sofern suboptimal, da nicht jeder Zahn in gleichem Maße Material ab tragen kann. So müßte beim Sägeblatt einer Stich- oder Säbelsäge je der Zahn - vom Einspannende des Sägeblatts her gesehen - geringfügig höher sein als sein vor ihm befindlicher Zahn, um in die von seinem Vorgänger ausgeräumte Nut noch tiefer einschneiden zu können. Dieser Effekt wird bei Stich- bzw. Säbelsägen durch einen zuschaltbaren Pendelhub nur unvollkommen erreicht, denn es fehlt an einem Säge blatt, das eigens auf die Kinematik des Pendelhubs solcher Hand werkzeugmaschinen abgestimmt ist und diesen optimal ausnutzt. The invention relates to a saw blade for wood or similar work substances according to the genus of the main claim. So far, saw saw blades for motorized jigsaws and saber saws straight Rows of teeth, such as B. emerges from DE-OS 27 50 969. At the However, working with these types of saws is a straight line of numbers if suboptimal, since not every tooth cuts material to the same extent can carry. So with a saw blade a jigsaw or saber saw would ever the tooth - from the clamping end of the saw blade - slightly be higher than his tooth in front of him, in order to be in his To be able to cut the previously cleared groove even deeper. This The effect of jigsaws or saber saws can be switched on Pendulum stroke only imperfectly achieved because there is no saw sheet, specifically on the kinematics of the pendulum stroke of such a hand machine tools and is optimally used.
Diese optimale Abstimmung auf den Bewegungsablauf von Stich- und Säbelsägen mit Pendelhub ist bei der erfindungsgemäßen Anordnung mit dem kennzeichnenden Merkmal des Hauptanspruchs verwirklicht. Durch die einwärts gebogene Form der Verzahnungsseite kommt es in Verbin dung mit der Pendelbewegung der Handwerkzeugmaschine zu einer dop pelten Ausräumbewegung beim Spanen. Durch diese Anordnung kann bei vergleichsweise geringem Kraftaufwand ein größerer Sägefortschritt erreicht werden als mit geradem Sägeblatt.This optimal adjustment to the movement of stitch and Saber saws with a pendulum stroke is in the arrangement according to the invention realized the characteristic feature of the main claim. By the inwardly curved shape of the toothing side comes into connection with the pendulum movement of the hand tool to a dop pelt clearing movement during cutting. With this arrangement, comparatively little effort a greater saw progress can be achieved than with a straight saw blade.
Ausführungsbeispiele der Erfindung sind in den Fig. 1 bis 3 in Seitenansicht dargestellt und in der nachfolgenden Beschreibung näher erläutert.Embodiments of the invention are shown in FIGS. 1 to 3 in side view and explained in more detail in the following description.
Wie aus den Figuren ersichtlich, unterscheidet sich das erfindungs gemäße Sägeblatt von einem herkömmlichen Sägeblatt mit gerader Zahn reihe dadurch, daß die Zahnreihe einwärts gebogen ist.As can be seen from the figures, the invention differs appropriate saw blade from a conventional saw blade with a straight tooth row in that the row of teeth is bent inwards.
Die Rücken des Sägeblatts kann dabei ebenfalls gebogen sein, wie in Fig. 1 dargestellt; oder ab der Einspannstelle zunächst gerade ver laufen und nur im vorderen Drittel abgeschrägt sein, wie in Fig. 2 dargestellt. Auch eine Kombination beider Merkmale ist möglich und in Fig. 3 dargestellt.The back of the saw blade can also be curved, as shown in Fig. 1; or run straight from the clamping point and just beveled in the front third, as shown in Fig. 2. A combination of both features is also possible and is shown in FIG. 3.
Entscheidend für die Funktion ist bei diesen, wie auch bei weiteren denkbaren, hier nicht dargestellten Ausführungsformen die Form der Zahnreihe. Durch deren Einwärtskrümmung werden die Zähne in der letzten Hälfte der Aufwärtsbewegung (d. h. in Richtung auf die Ein spannstelle des Sägeblatts hin) noch zusätzlich in das Werkstück eingezogen. Bei Sägemaschinen mit Pendelhub verstärkt diese Form der Zahnreihe den durch den Pendelhub erzielten Effekt. Sägemaschinen ohne Pendeleinrichtung können bei Verwendung des erfindungsgemäßen Sägeblatts angenähert in den Genuß der durch den Pendelhub erzielten Vorteile gelangen, die sich in größerem Sägefortschritt bei gerin gerer Andrückkraft manifestieren.Decisive for the function is with these as well as with others conceivable embodiments, not shown here, the shape of the Row of teeth. Due to their inward curvature, the teeth in the last half of the upward movement (i.e. towards the on clamping point of the saw blade) into the workpiece moved in. In the case of sawing machines with a pendulum stroke, this type of Row of teeth the effect achieved by the pendulum stroke. Sawing machines without a pendulum device when using the invention Saw blade approximates the enjoyment achieved by the pendulum stroke Advantages that can be seen in greater sawing progress at gerin manifest greater pressure.
