Description

Die Erfindung betrifft einen Flachmeißel und zwar einen Einsteckmeißel für kraftangetriebene Bohr- und Meißelhämmer zur Bearbeitung von Gestein nach dem Oberbegriff des Anspruchs 1.The invention relates to a flat chisel and that a Einsteckmeißel for power driven drill and chipping hammers for processing of rock according to the preamble of claim 1.

Derartige Flachmeißel kommen bei der Bearbeitung von Gestein, insbesondere Mauergestein zu Einsatz, um beispielsweise Durchbrüche, Kanäle und Schlitze herzustellen. Aus dem Stand der Technik sind Flachmeißel bekannt, deren Hauptschneide quer zu einer Meißellängsachse angeordnet ist. Nachteilig an derartigen Meißeln ist, dass diese insbesondere bei einer Bearbeitung, bei welcher der Meißel mit dem Meißelkopf tiefer in das Gestein eindringt, zum Verklemmen im Material neigen. Das Verklemmen im Material erfolgt insbesondere an den etwa senkrecht zur Schneide des Meißels orientierten Seitenflächen des Meißelkopfes.Such flat chisels are used in the processing of rocks, in particular wall rocks used to produce, for example, openings, channels and slots. Flat chisels are known from the prior art whose main cutting edge is arranged transversely to a longitudinal axis of the chisel. A disadvantage of such chisels is that they tend to jam in the material, especially in a processing in which the bit with the chisel head penetrates deeper into the rock. The jamming in the material takes place in particular on the approximately perpendicular to the cutting edge of the chisel oriented side surfaces of the chisel head.

Aus der EP 0 497 307 A2 ist ein Stechbeitel bekannt, welcher einen Schaft mit einer Einrichtung zum lösbaren Verbinden mit einer Werkzeugaufnahme einer schlagenden Handwerkzeugmaschine aufweist. Dieser weist einen Einspannschaft und einen Meißelkopf auf, wobei der Meißelkopf eine quer zu einer Meißellängsachse stehende Hauptschneide, eine vordere und eine hintere Schlagfläche und wenigstens eine die Schlagflächen verbindende Seitenfläche aufweist, wobei die Seitenfläche als Seitenschneide ausgebildet ist und wobei die Seitenschneiden Schneidflächen aufweisen.From the EP 0 497 307 A2 a chisel is known, which has a shaft with a device for releasable connection with a tool holder of a striking hand tool. This has a clamping shank and a chisel head, wherein the chisel head has a main cutting edge transverse to a longitudinal axis of the bit, a front and a rear striking surface and at least one side surface connecting the striking surfaces, wherein the side surface is formed as a side cutting edge and wherein the side cutting edges have cutting surfaces.

Der Erfindung liegt die Aufgabe zugunde, einen Flachmeißel zu entwickeln, der eine geringe Neigung zum Verklemmen im zu bearbeitenden Gestein aufweist.The invention has the object zugunde to develop a flat chisel, which has a low tendency to jamming in the rock to be processed.

Die Aufgabe wird in Verbindung mit dem Oberbegriff des Anspruchs 1 erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. In den Unteransprüchen sind vorteilhafte und zweckmäßige Weiterbildungen angegeben. Der erfindungsgemäße Flachmeißel weist wenigstens eine als Seitenschneide ausgebildete Seitenfläche aus. Durch die als Seitenschneide ausgestaltete Seitenfläche ist der Meißel in der Lage, das im Bereich der Seitenfläche befindliche Material zu bearbeiten. Durch diese Bearbeitung wird einem Verklemmen des Meißelkopfes im Gestein im Bereich der Seitenfläche vorgebeugt, da die als Seitenschneide ausgebildete Seitenfläche das zu bearbeitende Material in Form bringt. Somit wird Material, das den Meißelkopf im Bereich der Seitenfläche bremst, schon beim Eindringen des Meißels zerkleinert und aus dem Weg geräumt.The object is achieved in conjunction with the preamble of claim 1 according to the invention by the characterizing features of claim 1. In the dependent claims advantageous and expedient developments are given. The flat chisel according to the invention has at least one lateral surface designed as a side cutting edge. By designed as a side cutting side surface of the chisel is able to edit the material located in the area of the side surface. By this processing, a jamming of the bit head in the rock in the region of the side surface is prevented because the side surface formed as a side cutting edge brings the material to be machined in the form. Thus, material that brakes the chisel head in the area of the side surface, crushed as the chisel penetrates and cleared out of the way.

Unter einem Flachmeißel ist ein Meißel mit einer länglichen Schneidkante zu verstehen, die im Vüesentlichen senkrecht zu einer Meißellängsachse bzw. quer zu einer Schlagrichtung verläuft.A flat chisel is to be understood as meaning a chisel with an elongate cutting edge which is substantially perpendicular to a longitudinal axis of the bit or transverse to a direction of impact.

Gemäß einer vorteilhaften Ausbildung des Erfindungsgegenstandes geht wenigstens eine Seitenschneide in die Hauptschneide über. Hierdurch ist ein schneidenfreier Bereich vermieden, an dem es zu Verklemmungen des Meißels mit dem zu bearbeitenden Material kommen kann. Außerdem stabilisieren sich die Schneiden gegenseitig.According to an advantageous embodiment of the subject invention is at least one side cutting in the main cutting over. As a result, a cut-free area is avoided, which can lead to jamming of the bit with the material to be processed. In addition, the blades stabilize each other.

Eine vorteilhafte Ausbildung des Erfindungsgegenstandes sieht vor, die Schneidkanten der Hauptschneide und der Seitenschneide in einer gemeinsamen Ebene anzuordnen. Hierdurch ist eine Querbelastung der Schneiden bzw. Schneidkanten beim Vordringen bzw. Herausziehen des Flachmeißels aus dem Material weitgehend vermieden.An advantageous embodiment of the subject invention provides to arrange the cutting edges of the main cutting edge and the side cutting in a common plane. As a result, a transverse load on the cutting edges or cutting edges when advancing or pulling out the flat chisel from the material is largely avoided.

Durch eine im Querschnitt giebelförmige Ausführung der Hauptschneide und/oder Seitenschneide ist der Flachmeißel für die verschiedensten Anwendungsfälle und Ansetzwinkel geeignet. Mittels einer rampenförmigen Ausbildung der Hauptschneide und/oder Seitenschneide ist es möglich, besonders spitze Schneiden zu realisieren, die ein senkrechtes Eindringen in das zu bearbeitende Material begünstigen. Weiterhin erlauben derartig ausgebildete Schneiden ein besonders flaches Ansetzen des Meißels an das zu bearbeitende Material.By a gable-shaped in cross-section execution of the main cutting edge and / or side cutting the flat chisel for a variety of applications and attachment angle is suitable. By means of a ramp-shaped design of the main cutting edge and / or side cutting edge, it is possible To realize particularly sharp cutting edges, which promote a vertical penetration into the material to be machined. Furthermore, such trained cutting allow a particularly flat attachment of the bit to the material to be processed.

Weitere Einzelheiten der Erfindung werden in der Zeichnung anhand von schematisch dargestellten Ausführungsbeispielen beschrieben. Bei den Figuren handelt es sich teilweise um CAD-Darstellungen, in welchen die Meißel durch Gitternetzlinien dargestellt sind. Hierbei werden auch verdeckte Kanten als durchgezogene Linien dargestellt.Further details of the invention are described in the drawing with reference to schematically illustrated embodiments. The figures are partly CAD representations in which the chisels are represented by grid lines. Here also hidden edges are shown as solid lines.

Diese verbreitern sich in Richtung eines nicht dargestellten Einspannschaftes. Schneidkanten 17, 18 der Seitenschneiden 14, 15 verlaufen etwa in einem rechten Winkel zur Schneidkante 20 der Hauptschneide 7. Eine vordere Schlagfläche 10, in welche die Schneidflächen 8 und 16 übergehen, verläuft in einem Übergangsbereich 19 bis zum Meißelschaft 4. Die Hauptschneide 7 geht an Trennkanten 21 in die Seitenschneiden 14, 15 über. FIG. 2 shows a partial view of a second chisel 1 and second flat chisel 2, of which only a chisel head 3 and a part of the chisel shank 4 is shown.
