Description

WanssSeblatt. Die Erfindung bezieht sich auf ein kreisförmiges Warmaablatt zum Schaeiden oder Trennen stark erhitzten materialen. WanssSeblatt. The invention relates to a circular Strongly heat the warmaa leaf for peeling or separating materials.

Solche Warmsägeblätter sind an sich bekannte sie werden vielfach aus Stahl von etwa 85 - 90 kg Festigkeit hergestellt und in Naturhärte verwendet. Die Festigkeit des ungehärteten Stahles bestimmt die Standzeit der Sä- genzahne, man hat deshalb die Festigkeit aBglichat hoch gewählt, kann aber eine Festigkeit von 85-90 kg kaum überschreiten, da das Blatt zu leicht einreißen würde. Such hot saw blades are known per se, they are often made of steel of around 85-90 kg strength and used in natural hardness. The strength of the unhardened steel determines the service life of the teeth, one has therefore the strength aBglichat high chosen, but can hardly have a strength of 85-90 kg exceed because the sheet would tear too easily.

Trotzdem ist aber die Standzeit der Zähne nicht befriedigend.Nevertheless, the service life of the teeth is not satisfactory.

Man hat deshalb die Warmsägeblätter gehärtete und zwar wurde das ganze Blatt gehärtet. Eine solche Härtung ist aber. da mit ihr die Elastizität und Zähigkeit des Blattes abnimmt, nur bei kleineren Blättern durchführbar.The hot saw blades have therefore been hardened and the whole has been hardened Hardened sheet. Such a hardening is however. there with it the elasticity and toughness of the leaf decreases, only feasible with smaller leaves.

Das Warmeägeblatt der Erfindung besteht aus einem härtbarer Stahle <weckmäßig aus dem bereits fSr Warm- sägeblätter verwendeten Stahl von 85-90 kg Festigkeit, der einen für die Durchführung der Härtung ausreichenden Kohlenstoffgehalt hat. Bei diesem Blatt sind erfindungsgemäß die Zähne an ihren Spitzen, und zwar bis etwa zur halben Zahnhöhe gehärtet bzw. vergütet. Dadurch behalten das Blatt und die Zahnfüße ihre materialbegründete Elastizität und Zähigkeit, die im Zahngrund besonders wichtig ist, um das ßinreißen des Sägeblattes zu vermeiden, die Standzeit der Zähne ist aber durch ihre Härtung wesentlich erhöht.The heat saw blade of the invention consists of one hardenable steels saw blades used steel of 85-90 kg strength, which has a sufficient carbon content to carry out the hardening. In this blade, according to the invention, the teeth are hardened or tempered at their tips, specifically up to about half the tooth height. As a result, the blade and the tooth roots retain their material-based elasticity and toughness, which is particularly important in the tooth base in order to avoid tearing of the saw blade, but the service life of the teeth is significantly increased due to their hardening.

Auf der Zeichnung sind als Ausführungsbeispiele der Erfindung drei Segmente mit gebräuchlichen Zahnformen dargestellt, bei denen die ungefähre Höhe der gehärteten Zahnspitzen durch einen Querstrich angegeben ist. Die oberhalb des Striches liegenden Zahnspitzen sind auf 100-160kg Festigkeit vergütet und gehärtet. The drawing shows three exemplary embodiments of the invention Segments with common tooth shapes shown, for which the approximate height the hardened tooth tips is indicated by a slash. The one above the Line's lying tooth tips are tempered and hardened to a strength of 100-160kg.

und elastischen Stahl von etwa 85-90 kg Festigkeit bestehenden Sägeblattes gehärtet oder vergütet sind. In Zeile 2 des Schutzanspruches des Gebrauchsmus- ters 1 804 964 streiche ich die oho : "Zähneoder".
Damit lautet der Schutzanspruch nunmehr :
"Kreisförmiges Warmsägeblatt, dadurch gekennzeichnet, dass nur die Zahnspitzen des aus einem zähen und elastischen Stahl von etwa 85-90 kg Festigkeit bestehenden Sägeblattes gehärtet oder vergütet sind."and elastic steel of about 85-90 kg strength of the existing saw blade are hardened or tempered. In line 2 of the claim to protection of the utility model ters 1 804 964 I cancel the oho: "Teeth or".
The right to protection is now:
"Circular hot saw blade, characterized in that only the tooth tips of the saw blade, which is made of a tough and elastic steel with a strength of about 85-90 kg, are hardened or tempered."
