Die Erfindung betrifft ein Verfahren zum Herstellen eines Gattersägeblattes mit symmetrischen oder asymmetrischen Sägezähnen an mindestens einer Längskante. The invention relates to a method for producing a gang saw blade with symmetrical or asymmetrical Saw teeth on at least one longitudinal edge.
Das Herstellen von Sägeblättern soll nachfolgend an einem einseitig gezahnten Sägeblatt erläutert werden; die Herstellung beidseitig gezahnter Sägeblätter erfolgt sinngemäß.The manufacture of saw blades will be explained below using a saw blade toothed on one side; saw blades toothed on both sides are manufactured accordingly.
Zuerst wird das z. B. rechteckige Ausgangsmaterial gezahnt Nachfolgend wird der Sägeblattrucken durch Walzen — Strecken konvex gewölbt Dadurch wird die bereits gezahnte Vorderkante (Zahnreihe) gleichzeitig konkav gewölbt,, weil Vorder- und Hinterkante ihre Parallelität ja nicht verlieren können. Um nun eine geradlinige Zahnreihe zu erhalten, muß unter viel Arbeitsaufwand an Nachschleifarbeit die eingangs angebrachte Zahnreihe gerade geschliffen werden (siehe z. B. die DE-OS17 03 777).First the z. B. Rectangular starting material toothed Rolling - stretching convexly arched As a result, the already toothed front edge (row of teeth) is simultaneously concave, because the front and rear edges cannot lose their parallelism. To now one To get a straight row of teeth, must with a lot of work to regrind the initially attached row of teeth are ground straight (see e.g. DE-OS17 03 777).
Aufgabe der Erfindung ist es, das bekannte, erforderliche Nachschleifen der gezahnten Kante(n) einzusparen, das beim Herstellen von Gattersägeblättern erforderlich istThe object of the invention is to provide the known, required regrinding of the toothed edge (s) to save, which is necessary when manufacturing gang saw blades
Gelöst wird die gestellte Aufgabe durch die kennzeichnenden Merkmale des Patentanspruches.The problem posed is achieved by the characterizing features of the patent claim.
Im Nachfolgenden wird ebenfalls an einem einseitig gezahnten Sägeblatt die Erfindung mit ihren erheblichen Vorteilen erläutertIn the following, the invention with its considerable is likewise on a saw blade toothed on one side Advantages explained
Nach dem erfindungsgemäßen Verfahren wird das z.B. rechteckige Ausgangsmaterial durch Walzen = Strecken an einer Kante nämlich dem späteren Rücken des .Gattersägeblattes konvex gewölbt Damit wird gleichzeitig die Vorderkante des späteren gezahnten Gattersägeblattes durch das erfolgte Walzen konkav ausgebildet Dabei bleibt die Parallelität der Vorder- und Rückenkante des Ausgangsmaterials erhalten. Bis zu diesem Zeitpunkt ist noch keine Verzahnung durchgeführt worden. Erst jetzt wird dieses Ausgangsmaterial an seiner konkavem Kante — späteren Vorderkante — geradlinig gezahnt d.h. es wird ein einmaliger, in gerader Linie verlaufender Arbeitsgang durchgeführt Nun ist das erfindungsgemäße Gattersägeblatt fertig.According to the method according to the invention, the starting material, for example rectangular, is made by rolling = Stretching on one edge, namely the later back of the gang saw blade convexly arched becomes at the same time the leading edge of the later toothed gang saw blade due to the rolling that has taken place concave The parallelism of the front and back edges of the starting material remains obtain. Up to this point in time no interlocking has been carried out. Only now is this Starting material on its concave edge - later front edge - serrated in a straight line, i.e. it a single, straight-line operation is carried out. Now that is the invention Gang saw blade ready.
Die gleichen Arbeitsgänge werden zum Herstellen eines beidseitig gezahnten Sägeblattes durchgeführt nur daß vor dem Strecken die geradlinige Rückenkante des späteren Sägeblattes gezahnt wird.The same operations are carried out to produce a saw blade that is toothed on both sides only that the straight back edge of the later saw blade is toothed before stretching.
Durch die erfindungsgemäße Maßnahme wird neben Arbeitszeiteinsparung erreicht, daß auch eine Längenänderung der gestanzten Vorderkante der Verzahnung gegenüber der bekannten Art der Herstellung unterbleibt As a result of the measure according to the invention, in addition to saving working time, there is also a change in length the punched leading edge of the toothing is omitted compared to the known type of manufacture
Man spart aber nicht nur viel Nachschleifarbeit, sondern es wird auch die Vorschräinkung der Verzahnung, die von Sägenherstellern hauptsächlich zwecks Prüfens der Schränkfähigkeit vorgenommen wird, nicht in Mitleidenschaft gezogen. Bei den bekannten Herstellungsarten von Gattersägeblättern der gattungsgemäßen Art kommt es vor, daß das Schränken in den Endbereichen der Verzahnung vollkommen erneuert werden muß, um das richtige Schärfen vornehmen zu können.You not only save a lot of regrinding work, but also the pre-cutting of the toothing, which is carried out by saw manufacturers mainly to test the setting ability, not affected. In the known types of production of gang saw blades of the generic type It happens that the setting is completely renewed in the end areas of the toothing must be in order to be able to make the correct sharpening.
