Abstract
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 the stepwise variable radial fixing of the blades in cutter heads for 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 are operated at high speeds, which means that the knives are subjected to extremely high centrifugal forces during operation. This requires a sufficiently secure mounting of the knife in the cutter head, so that they can not move radially in operation under the influence of centrifugal forces. Because a possible radial displacement of a knife in the rapidly rotating cutter head would not only mean a significant risk of accidents, but also lead to the uselessness of the processed products.
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.In order to use the designed as a knife plates made of hard metal blades longer, it is desirable to clamp the blades after wear of the ground blade with radial offset outward again in the cutter head and reuse after appropriate regrinding of the blade can, or designed as inserts blade plates after wear of the cutting area at the first outer edge rotated by 180 ° to be able to tension again in the cutter head in order to use the cutting area on the previously inside and after turning the outside edge.
Eine derartige Vorrichtung geht beispielsweise aus der DE 89 06 924 U hervor.Such a device is for example known from DE 89 06 924 U.
Aus der US-A-2591 614 ist ein umlaufender Fräskopf mit mehreren am Umfang verteilten, in Schlitzen eingesetzten und axial gestaffelt angeordneten Schneidelementen bekannt, die jeweils an ihren Seitenkanten mit Zahnprofilen versehen sind und mit darin eingreifenden gezahnten Gegenprofilen zur radialen Festlegung zusammenarbeiten, wobei die Fixierung der Schneidelemente in dem Fräskopf durch axiales Zusammenspannen der Anordnung mittels Endscheiben an den axialen Enden des Fräskopfs erfolgt.From US-A-2591 614 a circumferential milling head with a plurality of circumferentially distributed, slotted inserted and axially staggered cutting elements is known, which are each provided at their side edges with tooth profiles and cooperate with engaging therein toothed counter profiles for radial fixing, wherein the Fixing of the cutting elements in the milling head by axially clamping the arrangement by means of end plates at the axial ends of the milling head.
Aus der US-A-1 380 686 ist ein umlaufender Fräskopf bekannt, bei dem, wiederum zwischen zwei axial zusammen spannbaren Endscheiben an diametral gegenüberliegenden Stellen Fräsmesser eingesetzt sind, die an ihren Seitenkanten mit einem Zahnprofil versehen sind, wobei mittels quer in einer der Endscheiben eingesetzten Gewindeschnecken eine stufenlose radiale Verstellung der Fräsmesser möglich ist.From US-A-1 380 686 a circumferential milling head is known in which, again between two axially tensionable together end discs at diametrically opposite locations are used cutting blades, which are provided at their side edges with a tooth profile, wherein means transversely in one of the end plates used threaded screw a stepless radial adjustment of the cutting blade is possible.
Aus der FR-A-859 584 ist ein Fräskopf zur Holzbearbeitung bekannt, bei dem sichelartige Messerelemente an ihren beiden Seitenkanten mit einer Zahnung versehen sind und zwei axiale Stirnplatten, die mit Schrauben axial zusammenspannbar sind, mit komplementären Zahnelementen versehen sind, um die Messerelemente stufig in ihrer Position verändern zu können.From FR-A-859 584 a milling head for woodworking is known in which sickle-like knife elements are provided at its two side edges with a toothing and two axial end plates, which are axially clamped with screws, are provided with complementary tooth elements to the knife elements stage to be able to change their position.
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 to provide a device for radial fixing of knife plates in fast rotating cutter heads, which ensures an absolutely slip-resistant radial fixing of the blade plate, further allows a gradual adjustability of the blade plate to at least one radial stage, and also easy and inexpensive to manufacture is.
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 specified in
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 at the two side edges of the blade plate, ie at the edges inserted in the knife head in the radial direction edges, ground wave profiles and in these two wave profiles positively engaging counter elements on the blade plate holder of the cutter head. The counter-elements can be formed with a corresponding design of the wave profile in its simplest embodiment as a cylindrical pin which engage with their lateral surface in each case in a corresponding bay of the respective wave profile, or they can, which is a preferred embodiment, be designed as claws, each one have to the wave profiles on the side edge portions of the blade plates complementary ground wavy profile and engage with their profile projections each in a profile bay of the blade plate. The wave profile on the side edges of the blade plate has, relative to the length of the blade plate edge provided therewith, a greater extent than the complementary counter-profile of the counter-elements, so that a radial adjustability of the blade plate by at least one stage, ie at least one wave pitch of the wave profile, is possible.
Die mit dem Wellenprofil versehenen Kantenbereiche der Messerplatte sind gegenüber dem übrigen Verlauf der Messerplattenseitenkanten zurückgesetzt, so daß jeweils eine seitliche Einbuchtung bzw. ein seitlicher Einschnitt an der Messerplatte gebildet ist.The provided with the wave profile edge portions of the blade plate are set back relative to the rest of the blade plate side edges, so that in each case a lateral recess or a lateral incision is formed on the blade plate.
Bei als Wendeplatten vorgesehene Messerplatten befinden sich die eingeschliffenen Wellenprofile natürlich jeweils in der Mitte der betreffenden Seitenkante.When provided as inserts blade plates are the ground wave profiles, of course, each in the 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 it is absolutely reliable with ease of manufacture. This advantage results in particular over conventional devices that work with breakthroughs in the blade plate and in this engaging counter-elements. Because breakthroughs in the blade plate are difficult to produce in the carbide, especially with the necessary accuracy, and where raw breakthroughs with plastic fillings are used to accommodate accurate holes, these holes are in relatively soft material.
