An Sägeblättern, insbesondere für Metal'lkreissägen, ist es bekannt, Zähne voller Breite mit schmalen Zähnen in abwechselnder Folge anzuordnen. Jedoch erwies sich sowohl· die Herstellung dieser Zähne wie auch das Schleifprofil für deren Instandhaltung als nicht einfach genug, da zu viel Arbeitsvorgänge und zumeist auch noch auf verschiedenen Maschinen erforderlich waren. Diesen ÜbelständenIt is known to have full-width teeth on saw blades, in particular for metal circular saws to be arranged in an alternating sequence with narrow teeth. However, both · the Manufacture of these teeth as well as the grinding profile for their maintenance is not easy enough, because there are too many work processes and mostly also on different machines were required. These evils
ίο wird nach vorliegender Erfindung dadurch abgeholfen, daß für die durch frühere Erfahrungen bewährten schmalen Vorschneid- oder Führungszähne eine besondere Ausgestaltung gewählt wird. Die schmalen Vorschneidzähne sind nach der vorliegenden Erfindung aus kalibriertem Flachstahl, wie er bisher zu Einsatzmessern für Fräser verwendet wurde, hergestellt, und zwar von solcher Stärke, daß sie den erprobten Abmessungen der bisher angewendeten .Vorschneidzähne von vornherein entsprechen und so alle seitherigen kostspieligen Formgebungs- und Instandhaltungsarbeiten vollkommen wegfallen.ίο is made according to the present invention helped that for the narrow pre-cutting or Guide teeth a special design is chosen. The narrow pre-cutting teeth are according to the present invention made of calibrated flat steel, as was previously the case with insert knives for milling cutters was used, produced, and indeed of such strength that they have the tried and tested dimensions of the previously used .Precision teeth correspond from the outset and thus all of the costly ones that have been made since Shaping and maintenance work are completely eliminated.
Gegenüber den seither bekannten Sägeblattausführungen dieser Art schafft man durch die vorstehend allgemein gekennzeichnete Erfindung ein Sägeblatt, das über die normale Breite nicht hinausgeht, dessen Herstellung überaus vereinfacht und dessen Instandhaltung auf jeder beliebigen Schleifmaschine ohne besondere Vorrichtung möglich ist. Die Herstellungskosten des Blattes werden fernerCompared to the saw blade designs of this type known since then, one manages the above generally characterized invention a saw blade that over the normal Width does not go beyond, the manufacture of which is extremely simplified and its maintenance is possible on any grinding machine without a special device. the Manufacturing costs of the sheet are also
durch die Anwendung des besonders geformten Zahnwerkstoffes in bezug auf Werkstoff- und Zeitverbrauch erheblich herabgesetzt.through the use of the specially shaped tooth material with regard to material and time consumption is significantly reduced.
Die Zeichnung veranschaulicht zwei Ausführungsbei spiele eines Sägeblattes gemäß der Erfindung in Abb. ι in Vorderansicht, Abb. 2 und 4 zeigen Aufsicht und Querschnitt, letzteren nach Linie A-B der Abb. 2 eines Blattes mit nur einem Vorschneidzahn, Abb. 3 und 5 stellen eine Aufsicht und einen Querschnitt nach Linie C-D der Abb. 3 eines Blattes mit paarweise nebeneinander angeordneten Vorschnei dzähnen dar.The drawing illustrates two Ausführungsbei games of a saw blade according to the invention in Fig. Ι in front view, Fig. 2 and 4 show plan view and cross section, the latter along line AB of Fig. 2 of a blade with only one pre-cutting tooth, Fig. 3 and 5 represent a Top view and a cross section along line CD of Fig. 3 of a sheet with precutting teeth arranged in pairs next to one another.
In den dargestellten Ausführungsbeispielen sitzen in dem Stammblatt c zwischen den breiten Zähnen α in schmalen Nuten die Vorschneidzähne b (Abb. 2 und 4) bzw. b1 (Abb. 3 und 5), welche einfach, paarweise oder mehrfach nebeneinander angeordnet sind und gegenüber den breiten Zähnen am Umfange um ao das Maß d vorstehen. Die schmalen Zähne b, b1 sind aus kalibriertem Flachstahl hergestellt. Ihre Stärke ist so gewählt, daß sie zu ihrer zweckentsprechenden Ausgestaltung keinerlei Formgebungsarbeit bedürfen.In the illustrated embodiments, the pre-cutting teeth b (Fig. 2 and 4) or b 1 (Fig. 3 and 5), which are arranged simply, in pairs or several times next to one another and opposite one another, sit in the master blade c between the wide teeth α in narrow grooves the broad teeth protrude by ao the dimension d. The narrow teeth b, b 1 are made from calibrated flat steel. Their strength is chosen so that they do not require any shaping work for their appropriate design.
