Description

Die Erfindung betrifft eine Vorrichtung zur stufig veränderbaren radialen Festlegung der Messer in Messerköpfen zur Holz- oder Kunststoffbearbeitung.The invention relates to a device for step change radial fixing of the knives in knife heads Wood or plastic processing.

Messerköpfe für die Holz- oder Kunststoffbearbeitung werden mit hohen Drehzahlen betrieben, wodurch die Messer im Betrieb enorm hohen Fliehkräften ausgesetzt sind. Dies erfordert eine ausreichend sichere Halterung der Messer im Messerkopf, damit diese sich im Betrieb nicht unter dem Einfluß der Fliehkräfte radial verschieben können. Denn eine mögliche radiale Verschiebung eines Messers im schnell rotierenden Messerkopf würde nicht nur eine erhebliche Unfallgefahr bedeuten, sondern auch zur Unbrauchbarkeit der bearbeiteten Produkte führen.Knife heads for wood or plastic processing operated at high speeds, causing the knives to operate are subjected to enormously high centrifugal forces. This requires one Sufficiently secure mounting of the knives in the knife head so that these are not affected by centrifugal forces during operation can move radially. Because a possible radial shift of a knife in the rapidly rotating knife head would not only mean a significant risk of accident, but also on the uselessness of the processed products to lead.

Um die als Messerplatten aus Hartmetall ausgebildeten Messer länger nutzen zu können, ist es wünschenswert, die Messerplatten nach Verschleiß der angeschliffenen Schneide mit Radialversatz nach außen erneut im Messerkopf einspannen und nach entsprechendem Nachschleifen der Schneide erneut verwenden zu können, oder als Wendeplatten ausgebildete Messerplatten nach Verschleiß des Schneidenbereichs an der zunächst außenliegenden Kante um 180° gedreht wieder im Messerkopf spannen zu können, um den Schneidenbereich an der zuvor innenliegenden und nach dem Umdrehen außen liegenden Kante nutzen zu können. To the knives, which are made of hard metal To be able to use it longer, it is desirable to use the knife inserts after wear of the ground cutting edge with radial misalignment outward in the cutter head and use again after re-sharpening the cutting edge to be able to, or knife plates designed as indexable inserts after wear of the cutting area on the first outer edge turned 180 ° again in the cutter head to be able to clamp the cutting area on the previously inside edge and after turning over outside edge to be able to use.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur radialen Festlegung von Messerplatten in schnell umlaufenden Messerköpfen zu schaffen, die eine absolut verrutschsichere radiale Festlegung der Messerplatte gewährleistet, weiter eine stufige Verstellbarkeit der Messerplatte um mindestens eine Radialstufe ermöglicht, und außerdem leicht und kostengünstig zu fertigen ist.The invention has for its object a device for the radial fixing of cutting inserts in fast rotating To create cutter heads that are absolutely slip-proof radial fixing of the knife plate ensures a step-by-step adjustability of the knife plate allows at least one radial step, and also light and is inexpensive to manufacture.

Diese Aufgabe wird gemäß der Erfindung durch die im Anspruch 1 mit ihren wesentlichen Merkmalen angegebene und in den Unteransprüchen vorteilhaft weiter ausgestaltete Vorrichtung gelöst.This object is achieved according to the invention by the in claim 1 with their essential characteristics and in the Advantageously further developed device solved.

Die erfindungsgemäße Vorrichtung besteht aus an den beiden Seitenkanten der Messerplatte, also an den bei im Messerkopf eingesetzter Messerplatte in Radialrichtung verlaufenden Kanten, eingeschliffenen Wellenprofilen und aus in diese beiden Wellenprofile formschlüssig eingreifenden Gegenelementen an der Messerplattenhalterung des Messerkopfes. Die Gegenelemente können bei entsprechender Gestaltung des Wellenprofils in ihrer einfachsten Ausführungsform als zylindrische Zapfen ausgebildet sein, die mit ihrer Mantelfläche jeweils in eine entsprechende Bucht des betreffenden Wellenprofils eingreifen, oder sie können, was eine bevorzugte Ausführungsform darstellt, als Krallen ausgebildet sein, die jeweils ein zu den Wellenprofilen an den Seitenkantenbereichen der Messerplatten komplementäres angeschliffenes Wellenprofil aufweisen und mit ihren Profilvorsprüngen jeweils in eine Profilbucht der Messerplatte eingreifen. Das Wellenprofil an den Seitenkanten der Messerplatte hat dabei, auf die Länge der damit versehenen Messerplattenkante bezogen, eine größere Ausdehnung als das komplementäre Gegenprofil der Gegenelemente, damit eine radiale Verstellbarkeit der Messerplatte um mindestens eine Stufe, d.h. mindestens eine Wellenteilung des Wellenprofils, möglich ist. The device according to the invention consists of the two Side edges of the knife plate, i.e. at the in the knife head inserted knife plate in the radial direction edges, ground wave profiles and out in these two Corresponding engaging counter elements on the wave profiles the knife holder of the knife head. The counter elements can with appropriate design of the wave profile in its simplest embodiment as a cylindrical pin be formed, each with its outer surface in one intervene in the corresponding bay of the relevant wave profile, or they can, which is a preferred embodiment represents, designed as claws, each one to the wave profiles on the side edge areas of the knife inserts have complementary ground wave profile and with their profile projections each in a profile bay engage the knife plate. The wave profile on the side edges the knife plate has to match the length of it provided knife edge, a larger extension as the complementary counter profile of the counter elements, thus a radial adjustability of the knife plate by at least one level, i.e. at least one wave division of the Wave profile, is possible.

Vorzugsweise sind die mit dem Wellenprofil versehenen Kantenbereiche der Messerplatte gegenüber dem übrigen Verlauf der Messerplattenseitenkanten zurückgesetzt, so daß jeweils eine seitliche Einbuchtung bzw. ein seitlicher Einschnitt an der Messerplatte gebildet ist.The edge regions provided with the wave profile are preferably the knife plate compared to the rest of the course Knife side edges reset, so that one side indentation or a side incision on the Knife plate is formed.

Bei als Wendeplatten vorgesehene Messerplatten befinden sich die eingeschliffenen Wellenprofile natürlich jeweils in der Mitte der betreffenden Seitenkante.Knife plates provided as indexable inserts are located the ground-in wave profiles of course in each case Middle of the relevant side edge.

Die erfindungsgemäße Festlegungsvorrichtung hat den Vorteil, daß sie bei leichter Herstellbarkeit absolut betriebssicher ist. Dieser Vorteil ergibt sich insbesondere gegenüber herkömmlichen Vorrichtungen, die mit Durchbrüchen in der Messerplatte und in diese eingreifenden Gegenelementen arbeiten. Denn Durchbrüche in der Messerplatte sind in dem Hartmetall schwierig herzustellen, vor allen Dingen mit der notwendigen Genauigkeit, und wo rohe Durchbrüche mit Kunststoffüllungen zur Aufnahme von genauen Bohrungen dienen, befinden sich diese Bohrungen in relativ weichem Material.The fixing device according to the invention has the advantage that they are absolutely reliable with easy manufacture is. This advantage arises in particular over conventional ones Devices with openings in the knife plate and work in these engaging counter elements. Because openings in the knife insert are in the hard metal difficult to manufacture, especially with the necessary Accuracy, and where raw breakthroughs with plastic fillings are used to accommodate precise holes these holes in relatively soft material.

Die seitlichen Einschnitte 14 mit dem eingeschliffenen Wellenprofil 15 befinden sich jeweils in der Mitte der Seitenkanten 13 der Messerplatte. Die Messerplatte ist also insoweit symmetrisch ausgebildet. Im übrigen ist die Ausbildung der Festlegungsvorrichtung mit den Einschnitten 14, den dort angeschliffenen Wellenprofilen 15, und den entsprechenden Gegenelementen 2 gleich wie beim Ausführungsbeispiel nach Fig. 1. 2 differs from the embodiment of FIG. 1 in that the knife plate 1 is designed as an indexable insert to grind of cutting edges on both their leading edge 11 and to allow the rear edge 12. The side incisions 14 with the ground-in wave profile 15 are located in each case in the middle of the side edges 13 of the knife plate. The In this respect, the knife plate is designed symmetrically. in the the rest is the design of the fixing device with the Notches 14, the wave profiles 15 ground there, and the corresponding counter elements 2 the same as in Embodiment according to Fig. 1st

Fig. 3 zeigt ein vereinfachtes Ausführungsbeispiel der erfindungsgemäßen Vorrichtung, das sowohl in Verbindung mit einer einfach verwendbaren Messerplatte als auch mit einer als Wendeplatte ausgebildeten Messerplatte anwendbar ist.Fig. 3 shows a simplified embodiment of the invention Device that is used in conjunction with a easy-to-use knife plate as well as with a turning plate trained knife plate is applicable.

Bei dieser vereinfachten Ausführungsform sind die Gegenelemente 2 als Zylinderstifte ausgebildet, die mit ihrer Mantelfläche direkt mit dem Wellenprofil 15 in den Einbuchtungen 14 der Seitenkanten 13 der Schneidplatte 1 eingreifen. In diesem Fall kann, wie aus der Zeichnung ersichtlich, auch das Wellenprofil vereinfacht sein, in dem es aus einer Aneinanderreihung halbkreisförmiger Wellenbuchten ausgebildet ist, während die Wellenhügel fehlen.In this simplified embodiment, the counter elements are 2 designed as cylindrical pins with their outer surface directly with the wave profile 15 in the indentations 14 the side edges 13 of the insert 1 engage. In this Fall, as can be seen from the drawing, also the wave profile be simplified by putting it together semi-circular wave bays is formed, while the wave hills are missing.
