Abstract

The saw blade (B) has a concave cut (b) over the entire width of the saw blade along the length of two flat sides, where the saw blade has more spaces in its concave cross section.

Description

Herkömmliche Stichsägeblätter im Werkzeugbereich des Handwerks und der HeimwerkerInnen für engen Kurvenschnitt sind an der Vorder- und Rückseite gezähnt und weisen einen parallelen Planschliff auf. Es ergibt sich ein Problem beim Schneiden von Kurven, dass das Sägeblatt ähnlich einer Eisenbahn in der Kurve nun mehr Breite benötigt. Dass soll durch die rückseitige Verzahnung erreicht werden. Sie verhindert aber nicht, dass der Innenradius des zu schneidenden Materials auf die Mitte des Sägeblattes drückt und an ihm reibt (A). Hierbei entstehen Reibungsverluste, das Sägeblatt erhitzt sich und verliert an Standvermögen. Das Sägeblatt wird nach aussen gedrückt, die innere Zahnreihe vom Material entfernt (a), was die Kurvengängigkeit mindert.conventional Jigsaw blades in the Tool area of craft and home improvement for narrow Curved sections are serrated on the front and back and have a parallel Surface grinding on. There is a problem with cutting curves, that the saw blade is similar to a Railroad in the bend now needs more width. That should be through the back Gearing can be achieved. But it does not prevent that Inner radius of the material to be cut on the center of the saw blade presses and rub against him (A). This results in friction losses, the saw blade heats up and loses stamina. The saw blade is pressed outwards, the inner row of teeth removed from the material (a), what the Kurvengängigkeit decreases.

Die Erfindung, für die ich Schutz begehre, ist ein Kurvenstichsägeblatt (B), das auf beiden Seiten mit einem kreisausschnittförmigen Hohlschliff über die ganze Länge des Hubes in der Breite des Sägeblattes versehen ist (C). Im weiteren kurz Sägeblatt mit Konkavschliff genannt. Beim Sägen in Kurven schmiegt sich nun das Material in den Hohlraum des Konkavschliffs hinein (b). Es hat erheblich weniger Reibung, die Kraft der Maschine wird auf den Sägevorgang konzentriert, engere Kurvenfahrt ist möglich, weil das Sägeblatt im Kurvenschnitt mehr Platz hat. Das Material des Sägeblattes wird geschont, weil die Erwärmung entsprechend geringer ist, die Standzeit erhöht sich.The Invention, for The one I seek protection is a cornerstitch saw blade (B), which is on both Sides with a circular cut Hollow over the full length of the stroke in the width of the saw blade is provided (C). In the following short called saw blade with concave cut. When sawing in curves, the material now nestles in the cavity of the concave cut into (b). It has considerably less friction, the power of the machine gets on the sawing process concentrated, tighter cornering is possible because the saw blade has more space in the curved section. The material of the saw blade is spared, because the warming is correspondingly lower, the service life increases.

Dieses bedeutet für gewerbliche Anwendung eine wesentliche Verbesserung, Qualitätssteigerung der Schnitte, weniger Materialausschuß u.a.m.This means for commercial application a substantial improvement, quality improvement of Cuts, less material scrap, etc.

Die Ausführung der beanspruchten Erfindung wird durch einen weiteren Herstellungsgang erreicht, indem dem Sägeblätt maschinell der Konkavschliff aufgebracht wird.The execution The claimed invention is characterized by a further production process achieved by machining the saw blade the concave cut is applied.
