Abstract
Description
Die Erfindung betrifft ein Schlagwerkzeug zum Zerkleinern von Materialien, insbesondere von Holzabfällen, mit einem Schaft und einem Meißelkopf, wobei an dem Meißelkopf ein Schneideinsatz befestigt ist.The invention relates to an impact tool for comminuting materials, in particular of wood waste, with a shank and a chisel head, wherein the chisel head a cutting insert is attached.
Ein solches Schlagwerkzeug ist aus der DE 35 45 708 C2 bekannt. Darin ist ein umlaufender Schlegel beschrieben, an dessen Grundkörper ein lösbar verbundener Schneidkörper angebracht ist. Der Schneidkörper ist als Zahn mit einem Schaft ausgebildet. Dabei trägt der Schaft einen aus einer Ausnehmung des einschwenkbar gelagerten Grundkörpers allgemein in Längsrichtung vorstehenden Schneidkopf von im wesentlichen dreieckigem Querschnitt, der die Schneidkante bestimmt. Durch eine Ausnehmung mit dreieckigem Querschnitt in der in Umlaufrichtung vorderen Fläche des Schneidkopfes wird eine Sollbruchstelle definiert, an welcher der Schneidkopf bei Überlastung, zum Beispiel durch Steine oder sonstige harte Gegenstände, an vorbestimmter Stelle bricht. Dabei ist die Sollbruchstelle so gelegt, dass der verbleibende Teil des Schneidkopfes den Schaft und seine Halterung vor Beschädigung schützt.Such a striking tool is known from DE 35 45 708 C2. That's one circulating Schlegel described on the body a releasably connected Cutting body is attached. The cutting body is as a tooth with a shaft educated. The shaft carries one of a recess of the einschwenkbar mounted main body generally longitudinally projecting cutting head of essentially triangular cross-section which determines the cutting edge. By a recess with triangular cross-section in the front in the circumferential direction Surface of the cutting head is defined a predetermined breaking point at which the Cutting head in case of overload, for example by stones or other hard ones Objects, at a predetermined point breaks. The predetermined breaking point is set in this way, that the remaining part of the cutting head before the shaft and its holder Damage protects.
Nachteilig bei dieser Anordnung ist, dass nach einem Bruch des Schneidkopfes die Schneidleistung des Schlägels nicht mehr gegeben ist. Dabei ist die Bruchgefahr für einen solchen Schneidkopf, der ohne rückseitige Stütze frei über den Grundkörper ragt, sehr groß, zumal mit der Sollbruchstelle ein Schwachpunkt des Bauteils vorgegeben ist.The disadvantage of this arrangement is that after a breakage of the cutting head the Cutting performance of the drumstick is no longer given. The risk of breakage for such a cutting head, the free without back support over the body protrudes, very large, especially with the breaking point a weak point of the component is predetermined.
Ein Schneidkörper mit verlängerter Lebensdauer wird in der G 93 05 835.7 beschrieben. Dabei ist der Schneidkörper im wesentlichen als Gussteil mit einer parallel zur Umlaufachse verlaufenden Schneidkante ausgebildet, wobei die Schneidkante mehrere nebeneinander angeordnete Teilkörper aus Hartmetall als Verschleißkörper aufweist.A cutting body with extended life is described in G 93 05 835.7 described. In this case, the cutting body is essentially as a casting with a formed parallel to the axis of rotation extending cutting edge, wherein the Cutting edge a plurality of juxtaposed carbide body parts as Wear body has.
Nachteilig bei dieser Anordnung ist, dass bei Bruch eines Teilkörpers das dahinter liegende Gussteil des Schneidkörpers ungeschützt der Belastung durch das zu zerkleinernde Material ausgesetzt ist. Der Verlust oder Bruch eines solchen Teilkörpers führt somit schnell zur Abnutzung des Gussteils mit der für die Aufnahme der Teilkörper vorgesehenen Ausnehmung.The disadvantage of this arrangement is that in case of breakage of a part of the body behind it lying casting of the cutting body unprotected the burden of the crushing material is exposed. The loss or breakage of such Part body thus quickly leads to wear of the casting with the recording the part body provided recess.
Es ist Aufgabe der Erfindung, ein Schlagwerkzeug der eingangs erwähnten Art zu schaffen, das eine verlängerte Lebensdauer bei verbesserter Zerkleinerungsleistung ermöglicht. It is an object of the invention to provide a striking tool of the type mentioned create a longer life with improved crushing performance allows.
Die Aufgabe der Erfindung wird dadurch gelöst, dass der Schneideinsatz wenigstens ein erstes und wenigstens ein zweites Schneidelement aufweist und dass die ersten und zweiten Schneidelemente in Schneidrichtung hintereinander angeordnet sind. Bei Bruch oder Verlust eines der der Schlagbelastung hauptsächlich ausgesetzten vorderen Schneidelemente steht ein nachgeordnetes Schneidelement zur Verfügung, welches sowohl die Schneidaufgaben wie den mechanischen Schutz des dahinter liegenden, nur ungenügend schlag- und abriebfesten Meißelkopfes übernimmt.The object of the invention is achieved in that the cutting insert at least a first and at least one second cutting element and that the first and second cutting elements are arranged one behind the other in the cutting direction. In case of breakage or loss of one of the impact load mainly exposed Front cutting elements is a downstream cutting element available, which both the cutting tasks as the mechanical protection of the behind lying, insufficiently shock and abrasion resistant chisel head takes over.
Bevorzugt ist der Schneideinsatz so aufgebaut, dass er zwei oder mehrere erste und/oder zweite Schneidelemente aufweist, die quer zur Schneidrichtung nebeneinander angeordnet sind. Aufgrund der dadurch bedingten geringeren Abmessungen der Schneidelemente ist die Biegebelastung der einzelnen Elemente im Betrieb verringert, was zu einem verminderten Bruchausfall führt. Weiterhin stehen bei Ausfall eines Schneidelementes die benachbarten Elemente weiterhin zur Verfügung.Preferably, the cutting insert is constructed to have two or more first ones and / or second cutting elements which are transverse to the cutting direction next to each other are arranged. Due to the resulting lower Dimensions of the cutting elements is the bending load of the individual elements reduced during operation, resulting in a reduced breakage failure. Farther stand in case of failure of a cutting element, the adjacent elements continue to Available.
Sind die ersten und/oder die zweiten Schneidelemente plattenförmig ausgebildet und weisen sie zwei oder mehr Zähne auf, die quer zur Schneidrichtung nebeneinander angeordnet sind, wird eine verbesserte Zerspanung faserhaltiger Stoffe wie Holz erreicht.Are the first and / or the second cutting elements plate-shaped and they have two or more teeth side by side transversely to the cutting direction are arranged, improved cutting of fibrous materials such as wood reached.
Weist der Meißelkopf eine entgegen der Schneidrichtung an den Schneideinsatz anschließende Freifläche auf und weist die Freifläche eine zumindest bereichsweise an die Außenkontur des Schneideinsatzes angepasste Profilierung auf, ist die Abstützung des Schneideinsatzes besonders formstabil und er behält auch unter Belastung seine für eine gute Zerkleinerungsleistung erforderliche Ausrichtung zum Zerkleinerungsgut. Der Meißelkopf stellt dabei durch die Profilierung dem Schneidgut keinen zusätzlichen Widerstand entgegen.Does the bit head one against the cutting direction of the cutting insert subsequent open space and has the open space at least partially On the outer contour of the cutting insert adapted profiling, which is Support of the cutting insert particularly dimensionally stable and he also retains Loading its required for a good crushing performance alignment Comminution material. The chisel head provides the material to be cut by the profiling no additional resistance.
Eine dauerhafte und formstabile Halterung der Schneidelemente des Schneideinsatzes am Meißelkopf wird dadurch erreicht, dass der Meißelkopf eine Aufnahme für den Schneideinsatz aufweist, die zwei im Winkel zueinander stehende Stützflächen aufweist, wobei die erste Stützfläche sich im wesentlichen in Schneidrichtung erstreckt, dass die ersten und zweiten Schneidelemente auf dieser Stützfläche abgestützt sind, dass das in Schneidrichtung hinter dem ersten Schneidelement angeordnete zweite Schneidelement mit seiner Rückseite an der zweiten Stützfläche abgestützt ist und dass sich das erste Schneidelement rückseitig an der Vorderseite des zweiten Schneidelementes abstützt.A permanent and dimensionally stable mounting of the cutting elements of the cutting insert At the chisel head is achieved by the fact that the chisel head a recording for the cutting insert, the two at an angle Supporting surfaces, wherein the first support surface is substantially in Cutting direction extends that the first and second cutting elements on this Support surface are supported, that in the cutting direction behind the first Cutting element arranged second cutting element with its back on the second support surface is supported and that the first cutting element on the back supported at the front of the second cutting element.
In einer bevorzugten Ausführungsform bestehen das erste und zweite Schneidelement aus Hartwerkstoffen unterschiedlicher Qualität. So kann das erste, in Umlaufrichtung vordere Schneidelement aus einem hochwertigeren, widerstandsfähigeren Material hergestellt werden, während das rückseitige Schneidelement aus einem kostengünstigeren Material gefertigt sein kann.In a preferred embodiment, the first and second exist Cutting element made of hard materials of different quality. So the first, in the direction of rotation front cutting element of a higher quality, more resistant material, while the back Cutting element can be made of a less expensive material.
Eine formstabile Abstützung der Schneideinrichtung bei gleichzeitiger Verhinderung des Verklemmens des Schlagwerkzeuges wird erreicht, indem der Meißelkopf eine gegenüber der Schneidrichtung geneigte Freifläche aufweist, die sich entgegen der Schneidrichtung an den Schneideinsatz anschließt und indem das erste Schneidelement über das zweite Schneidelement in die Freifläche übergeleitet ist.A dimensionally stable support of the cutting device while preventing the jamming of the impact tool is achieved by the chisel head a has inclined to the cutting direction inclined free surface, which opposes the Cutting direction connects to the cutting insert and by the first Cutting element is transferred via the second cutting element in the open space.
