Abstract
Description
Die Erfindung betrifft eine Vorschubeinrichtung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a feed device according to the Preamble of claim 1.
Die Übertragung der Vorschubkräfte erfolgt in Holzbearbeitungs maschinen i.A. durch Vorschubwalzen, deren Drehachsen senkrecht zur Vorschubrichtung angeordnet sind. Durch den Kontakt der Mantelfläche der Vorschubwälzen mit der Holzoberfläche wird die Vorschubkraft über Kraft- und/oder Formschluß auf das Werkstück übertragen.The feed forces are transferred in woodworking machines i.A. by feed rollers, whose axes of rotation are perpendicular to Feed direction are arranged. Through the contact of the The lateral surface of the feed rollers with the wooden surface is the Feed force via force and / or form fit on the workpiece transfer.
Durch die Achsanordnung ist es an vielen Stellen nicht möglich, den Krafteinleitungsort beliebig in der Maschine zu positionieren. Insbesondere bei der Bearbeitung mit Messerwellen ergibt sich ein Mindestabstand zwischen der Wirkstelle der Bearbeitungswelle und der Vorschubwalze bzw. zwischen zwei Vorschubwalzen. Diese Mindestabstände schränken die Bearbeitung von kurzen Werkstücken in den Maschinen ein, bzw. bedingen eine Verringerung der Qualität der Bearbeitung.Due to the axis arrangement, it is not possible in many places Position the force application location anywhere in the machine. This results in particular when machining with knife shafts Minimum distance between the working point of the machining shaft and the feed roller or between two feed rollers. These Minimum distances restrict the processing of short workpieces in the machines, or cause a reduction in the quality of the Editing.
Des weiteren ist die Kontaktfläche zwischen den Vorschubwalzen und dem Werkstück durch die Krümmung der Oberfläche der Vorschubwalzen an der Krafteinleitungsstelle begrenzt. Dies bedingt eine Begrenzung für die Einleitung der Vorschubkräfte.Furthermore, the contact area between the feed rollers and the workpiece due to the curvature of the surface of the feed rollers limited at the point of force application. This requires one Limitation for the introduction of the feed forces.
Das Problem der Erfindung besteht darin, die übertragbaren Vorschubkräfte mittels einer Vorrichtung zu erhöhen.The problem with the invention is that of being transferable To increase feed forces by means of a device.
Erfindungsgemäß wird die Aufgabe mit den in den Ansprüchen genannten und im Ausführungsbeispiel näher erläuterten Mitteln gelöst.According to the invention the task with the in the claims mentioned means and explained in more detail in the embodiment solved.
Durch die rage der Drehachse des schraubenförmigen Vorschubelements ist eine wesentliche Vergrößerung der möglichen Kontaktfläche zwischen Vorschubelement und Werkstück möglich. Die übertragbare Vorschubkraft kann damit in weiten Grenzen variiert werden und kann größer als bei herkömmlichen Vorschubwalzen sein.Due to the protrusion of the axis of rotation of the helical feed element is a significant increase in the possible contact area possible between feed element and workpiece. The transferable Feed force can and can be varied within wide limits be larger than with conventional feed rollers.
Die Krafteinleitung erfolgt linienförmig in der Richtung der Vorschubbewegung. Dies ermöglicht eine sichere Einleitung der Vorschubkraft auch bei extrem kurzen Werkstücken.The force is applied linearly in the direction of the Feed motion. This enables a safe initiation of the Feed force even with extremely short workpieces.
Die vorgeschlagene Einrichtung ermöglicht eine Verringerung des konstruktiv bedingten Abstandes zwischen den Vorschubelementen und anderen Maschinenteilen, z. B. von Bearbeitungswellen.The proposed facility allows a reduction in design-related distance between the feed elements and other machine parts, e.g. B. machining shafts.
Die Einrichtung kann sowohl unterhalb eines Maschinentisches, als auch über dem Werkstück angeordnet werden.The device can both below a machine table, as can also be arranged over the workpiece.
Durch die Drehrichtung, die senkrecht zur Vorschubrichtung liegt, kann eine definierte Anlagekraft an einem seitlichen Anschlag erreicht werden, was eine definierte Führung ohne zusätzliche seitliche Führungselemente ermöglicht.Due to the direction of rotation, which is perpendicular to the feed direction, can have a defined contact force on a side stop what a defined leadership can be achieved without additional allows lateral guide elements.
Die Erfindung wird nachstehend an einem Ausführungsbeispiel näher erläutert. In den Zeichnungen zeigenThe invention is illustrated below using an exemplary embodiment explained. Show in the drawings
Fig. 1 eine erfindungsgemäße Lösung in schematischer Darstellung als Seitenansicht Fig. 1 shows a solution according to the invention in a schematic representation as a side view
Fig. 2 eine zu Fig. 1 gehörige Vorderansicht. Fig. 2 is a front view belonging to Fig. 1.
In Fig. 1. wird eine erfindungsgemäße Lösung in schematischer Darstellung gezeigt. Ein zylindrisches Vorschubelement 1 ist unterhalb der Auflageebene 4 angeordnet. Die Drehachse 5 des Vorschubelements liegt parallel zur Vorschubrichtung 7. Das Vorschubelement ist auf der Zylinderfläche schraubenförmig verzahnt. Die vorderen Flanken der Verzahnung stehen senkrecht zur Drehachse. Die Verzahnung ragt über ein bestimmtes Maß über die Auflageebene 4 hinaus, wodurch die Größe des Formschlusses zwischen Vorschubelement und Werkstück 3 bestimmt wird.A solution according to the invention is shown in a schematic representation in FIG . A cylindrical feed element 1 is arranged below the support plane 4 . The axis of rotation 5 of the feed element lies parallel to the feed direction 7 . The feed element is helically toothed on the cylinder surface. The front flanks of the toothing are perpendicular to the axis of rotation. The toothing protrudes beyond the support plane 4 by a certain amount, as a result of which the size of the positive connection between the feed element and the workpiece 3 is determined.
Die notwendige Normalkraft 8 zur Erzeugung des Reib- und Formschlusses zwischen Vorschubelement und Werkstück wird durch zwei Druckelemente 11, die als Andruckrollen ausgelegt sind, erzeugt.The necessary normal force 8 for generating the frictional and positive connection between the feed element and the workpiece is generated by two pressure elements 11 , which are designed as pressure rollers.
Durch Drehung des Vorschubelementes um seine Drehachse wird eine seitliche Führungskraft 8 erzeugt. Diese Kraft wird vorteilhaft gegen einen seitlichen Anschlag 9 abgestützt. Damit wird das Werkstück faktisch von selbst geführt.A lateral guide force 8 is generated by rotating the feed element about its axis of rotation. This force is advantageously supported against a lateral stop 9 . In fact, the workpiece is guided by itself.
