Description

Vorrichtung zum Schleifen länglicher Werkstücke mit beliebigem Querschnitt Gegenstand der Erfindung ist eine Vorrichtung zum Schleifen länglicher Werkstücke mit beliebigem Querschnitt, bei der das Werkstück in einer Einspannvorrichtung um seine Längsachse zwangläufig drehend befestigbar und gegen ein endloses umlaufendes Schleifband anstellbar ist.Device for grinding elongated workpieces with any cross-section The invention relates to a device for grinding elongated workpieces with any cross-section, in which the workpiece in a clamping device around its longitudinal axis inevitably rotatable and fastened against an endless revolving Sanding belt is adjustable.

Es sind bereits Schleifmaschinen zum Abschleifen von Holzstücken mit beliebigem Querschnitt mit einem in Bewegung befindlichen, über ein feststehendes Formstück laufendes Schleifband bekannt.There are already grinding machines for sanding down pieces of wood with any cross-section with a moving one, over a stationary one Fitting running sanding belt known.

Es sind weiter auch schon Schleifmaschinen bekannt, bei welchen sich das endlose Schleifband zwischen einer entgegengesetzt zum Werkstück angetriebenen Formscheibe und dem Werkstück hindurchbewegt, wobei jedoch der Andruck von der Formscheibe auf das Werkstück starr gehalten ist. In beiden Fällen ist jedoch kein feiner Abschliff am Werkstück gewährleistet, und außerdem tritt ein großer Bandverschleiß auf.There are also grinding machines known in which the endless sanding belt between one driven in the opposite direction to the workpiece Shaped disk and the workpiece moved through, but the pressure from the shaped disk is held rigidly on the workpiece. In both cases, however, there is no fine sanding down guaranteed on the workpiece, and there is also a great deal of wear and tear on the belt.

Um die genannten Mängel zu beseitigen, wird nach der vorliegenden Erfindung erfindungsgemäß eine Bandschleifvorrichtung vorgeschlagen, bei der das umlaufende Band sich dauernd schmiegsam an das Werkstück anlegt und dasselbe mit gleichmäßigem Bandandruck auf seine ganze Länge abgeschliffen wird. Dies wird durch eine gegen das umlaufende Schleifband federnd drückende Spannrolle, die starr mit einer einstellbaren Anlaufrolle verbunden ist, welche an einer mit dem Werkstück sich drehenden, auswechselbaren, der Querschnittsform des Werkstückes entsprechenden Schablone abläuft, erreicht.In order to eliminate the shortcomings mentioned, according to the present Invention proposed according to the invention a belt grinding device in which the The circumferential band is constantly pliable against the workpiece and the same with it is sanded down evenly over its entire length. This is going through a tensioning roller that resiliently presses against the rotating sanding belt and that is rigidly attached to it an adjustable run-up roller is connected, which on a with the workpiece rotating, interchangeable, corresponding to the cross-sectional shape of the workpiece Stencil expires, reached.

Beim Schleifen von längsprofilierten Werkstücken wird weiter vorgeschlagen, am Spannrollenträger ein der Werkstückform angepaßtes oder sich selbst anpassendes Bandwiderlager, im ersten Falle in Form einer Filzplatte, im zweiten Falle in Form einer luftgefüllten Gummiwalze bzw. Schaumgummiauflage, anzubringen.When grinding longitudinally profiled workpieces, it is also suggested that on the tensioning roller carrier one that is adapted to the shape of the workpiece or one that is self-adapting Belt abutment, in the first case in the form of a felt plate, in the second case in the form an air-filled rubber roller or foam rubber pad.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt.The drawing shows an exemplary embodiment of the subject matter of the invention shown.

Abb. 1 zeigt die Seitenansicht der Schleifvorrichtung zum Schleifen von geradlinigen Werkstücken mit verschiedener Querschnittsform, Abb.2 die Seitenansicht des Spannrollenträgers mit eingesetztem Bandwiderlager und Abb. 3 die Draufsicht auf das Bandwiderlager.Fig. 1 shows the side view of the grinding device for grinding of rectilinear workpieces with different cross-sectional shapes, Figure 2 shows the side view of the tension roller carrier with inserted belt abutment and Fig. 3 the top view on the belt abutment.

Die in dem Maschinengestellt gelagerte und von einem Elektromotor angetriebene Bandantriebsrolle 2 treibt das endlose Schleifband 4 an, das über die Bandrolle 3 geführt ist. Der Spannrollenträger 5, der vermittels der Feder 7 mit dem Maschinengestell 1 verbunden wird, ist schwenkbar im Maschinengestell 1 angeordnet und trägt im mittleren Teil die Spannrolle 6, die federnd gegen das umlaufende Schleifband 2 drückt. Der Spannrollenträger 5 ist starr mit einem Ansatz 8 versehen, an dessen Ende die Anlaufrolle 9 verstellbar befestigt ist. Die Anlaufrolle 9, die seitlich am Schleifband 2 vorbeigeht, drückt auf die mit dem Werkstück 10 sich drehende Schablone 11, wodurch der gleichmäßige Bandandruck auf das Werkstück hergestellt wird.The one stored in the machine frame and powered by an electric motor driven belt drive roller 2 drives the endless sanding belt 4, which is on the Tape roll 3 is guided. The tension roller carrier 5, which by means of the spring 7 with is connected to the machine frame 1, is arranged pivotably in the machine frame 1 and carries in the middle part the tensioning roller 6, which resiliently against the rotating sanding belt 2 presses. The tension roller carrier 5 is rigidly provided with a projection 8, at which The end of the run-up roller 9 is adjustably attached. The start-up roller 9, the side goes past the grinding belt 2, presses on the template rotating with the workpiece 10 11, whereby the even tape pressure is produced on the workpiece.

Beim Schleifen von längsprofilierten Werkstücken wird an Stelle der Anlaufrolle 9 ein der Werkstückform angepaßtes oder sich selbst anpassendes Bandwiderlager 12 befestigt, durch welches das Schleifband elastisch auf das Werkstück gedrückt wird.When grinding longitudinally profiled workpieces, the Start-up roller 9 is a belt abutment which is adapted to the shape of the workpiece or which adapts to itself 12 attached, through which the sanding belt is pressed elastically onto the workpiece will.
