Abstract

The rectangular saw blade (1) made of cold rolled steel has the edge opposite the toothed part mechanically processed in a way that its surface (1,2), which has been uneven after if it has been cut alongside, is smooth and straight. At least 0.2 mm have to be removed in thickness to produce a surface which is even all over.

Description

Gatter- und Bandsägeblätter werden vorwiegend aus kaltgewalztem Bandstahl hergestellt, der im Rücken eine vom Walzen her arrondierte Kante aufweist. Diese Stähle sind von der Herstellung teuer, da sie nicht aus breiteren Bändern als Spaltmaterial herstellbar sind.Frame and band saw blades are mainly made of cold rolled steel strip made in the back has a rounded edge from the rolling. These steels are expensive to manufacture because not from wider bands than fissile material are producible.

Der Erfindung liegt die Aufgabe zugrunde, Langsägeblätter aus kaltgewalztem Stahl herzustellen, der aus breiten Bändern aufgespalten ist, wobei die Ausgangsbandbreite ein ganzes Vielfaches der Sägenbreite ist.The invention has for its object, rip saw blades to manufacture from cold-rolled steel, which from broad Bands is split, the output bandwidth is a whole multiple of the saw width.

Die aufgespaltenen Sägeblätter haben an der Spaltstelle eine Verwerfung durch den Scherprozeß, so daß an dieser Kante die Ebenheit des Sägeblattes nicht mehr gegeben ist. Außerdem sind die Scherflächen rißanfällig.The split saw blades have at the splitting point a fault by the shear process, so that at the flatness of the saw blade no longer given is. The shear surfaces are also prone to cracking.

Das erfindungsgemäße Sägeblatt ist aus Bandstahl hergestellt, dessen Verwerfungszone auf einer Seite durch mechanische Bearbeitung der Banddicke so gestaltet ist, daß im Sägenrücken kein Bereich über die Seitenfläche des Sägeblattes hervorsteht und in einer Sonderausführung der Rücken durch mechanische Bearbeitung so weit abgetragen ist, daß die Schermikro­ risse entfernt sind.The saw blade according to the invention is made of steel strip manufactured, whose fault zone on one side by mechanical processing of the strip thickness is designed so that there is no area in the back of the saw the side surface of the saw blade protrudes and in a special version the back by mechanical Processing is worn so far that the shear micro cracks are removed.

Die einzige Figur zeigt das Sägeblatt (1) mit der zu bearbeitenden Kantenfläche (1.1) und dem ent­ sprechenden Abtrag (A) und die Schrägungsfläche (1.2), um den Überstand (B) zu entfernen, der durch die Verbiegung beim Scheren entstanden ist, wobei die Schrägungsfläche (1.2) unter dem Schrägungswinkel (α) dergestalt angeordnet ist, daß in diesem Bereich kein Material über die Seitenfläche des Sägeblattes hervorsteht. The single figure shows the saw blade ( 1 ) with the edge surface to be machined ( 1.1 ) and the corresponding removal (A) and the bevel surface ( 1.2 ) in order to remove the overhang (B) which was caused by the bending during shearing, wherein the bevel surface ( 1.2 ) is arranged at the bevel angle (α) such that no material protrudes from the side surface of the saw blade in this area.
