Abstract

The circular saw blade with side cutting surfaces has at least in vicinity of the teeth of the blade (1) cutting apertures (3) a solder surface (6), which at least at one end evolves into a transition arc (7). The transition arc on a maximum base corresponds to a five twelfth circle and in special format to a quarter circle. In a special format at least one end hole (4) is connected by a slot (5) with the solder surface (6) or with a transition arc. The end hole can be replaced by a slot in straight, circular or spiral shape.

Description

Die Seitenschneiden der bekannten Kreissägen haben den Nachteil, daß sich die Übergangsbögen an den Enden der Seitenschneidenleisten - insbesondere am radial äusseren Ende - mit Holzspänen verstopfen und zu Verbrennungen führen aufgrund der mindestens halbkreisförmigen Form der Übergangsbögen, die somit einen radialen Druck auf die Holzspäne ermöglichen. Außerdem wird das Sägeblatt durch die relativ große radiale Öffnung geschwächt.The side edges of the known circular saws have the disadvantage that the transition arches at the ends of the side cutting edges - in particular at the radially outer end - clog with wood chips and lead to burns due to the at least semicircular shape the transition arches, thus putting radial pressure on the wood chips enable. In addition, the saw blade is due to the relatively large radial Opening weakened.

Der Erfindung liegt die Aufgabe zugrunde, eine Seitenschneidenform zu schaffen, in der sich die Holzspäne nicht mehr radial verklemmen können und die eine kürzere radiale Länge aufweisen.The invention has for its object to provide a side cutting shape, in which the wood chips can no longer jam radially and the shorter ones have radial length.

Das erfindungsgemäße Sägeblatt weist Seitenschneidenöffnungen auf, die mindestens an einem Ende der Lötflächen in einen Übergangsbogen übergehen, der maximal etwa einem 5/12 Kreis entspricht, in Sonderausführung etwa einem Viertelkreis und daß im Lötflächenbereich Endlöcher angeordnet sind, die durch Verbindungsschlitze mit den Lötflächen verbunden sind. The saw blade according to the invention has side cutting openings that merge into a transition arc at least at one end of the soldering areas, which corresponds to a maximum of about 5/12 circles, in a special version about one Quarter circle and that end holes are arranged in the soldering area, through Connection slots are connected to the solder pads.  

Die einzige Figur zeigt das erfindungsgemäße Sägeblatt (1) in teilweiser Seitenansicht mit der Seitenschneidenöffnung (3), der Lötfläche (6), dem Übergangsbogen (7) und den Endlöchern (4), die mittels der Übergangsschlitze (5) mit der Lötfläche (6) verbunden sind. Die Seiten­ schneidenleiste (2) mit ihrer Leistenabschrägung (2.1) ist mit dem Säge­ blatt (1) über die Lötfläche (6) verbunden. The single figure shows blade (1) according to the invention in partial side view with the side cutting opening (3), the soldering surface (6), the transition arc (7) and the end holes (4), by means of the transition slots (5) with the soldering surface (6 ) are connected. The side cutting bar ( 2 ) with its bevel ( 2.1 ) is connected to the saw blade ( 1 ) via the soldering surface ( 6 ).
