Description

Die Erfindung betrifft eine Vorrichtung zum Beschneiden von Holzbrettern auf Holzbearbeitungsmaschinen unter Verwendung eines Gerätes zum Verschieben der Werkstücke auf dem Maschinentisch mit Hilfe von motorisch angetriebenen Rollen od. dgl.The invention relates to a device for trimming wooden boards on woodworking machines using a device for moving the Workpieces on the machine table with the help of motor-driven rollers or like

Es ist schwierig und mühsam, Holzbretter auf Kreissägen zu besäumen. Bei Zuhilfenahme von sogenannten Vorschubapparaten, das sind Geräte mit das Werkstück belastenden, motorisch angetriebenen Rollen, wird die Schnittfläche krumm, weil die Führung des Werkstückes ungenügend ist. Werden dagegen nach der Erfindung zwischen den Maschinentisch und das Werkstück mehrere vorzugsweise metallene Leisten eingebaut, die sich in der Vorschubrichtung des' Werkstückes erstrecken, so entstehen die gewünschten, geraden Schnittflächen.It is difficult and tedious to trim wooden boards on circular saws. With the help of so-called feed devices, these are devices with the workpiece stressful, motor-driven rollers, the cut surface becomes crooked because the guidance of the workpiece is insufficient. However, according to the invention between the machine table and the workpiece have several preferably metal strips built in, which extend in the feed direction of the 'workpiece, this creates the desired, straight cut surfaces.

Die Leisten können in einen brettförmigen Leistenträger eingelassen sein, der lösbar mit dem Maschinentisch verbunden ist. In diesem Fall kann eine Kreissäge, die zum Besäumen verwendet worden ist, durch Ausbau der Vorrichtung rasch wieder in denjenigen Zustand umgebaut werden, in dem sie feinere Arbeiten ausführen kann. Herausgefunden wurde ferner, daß es zweckmäßig ist, die Auflageflächen der Leisten für das Werkstück etwa 0,5 mm breit und gegebenenfalls abgerundet bzw. stumpfkegelig angeschrägt zu machen.The strips can be embedded in a board-shaped strip carrier which is detachably connected to the machine table. In this case, a circular saw that has been used for trimming can be quickly converted back into the condition in which it can carry out finer work by removing the device. It was also found that it is expedient to make the contact surfaces of the strips for the workpiece about 0.5 mm wide and, if necessary, rounded or bevelled in a frustoconical manner.

In der Zeichnung ist ein Ausführungsbeispiel schematisch im Querschnitt dargestellt. Auf dem Maschinentisch i ist der brettförmige, aus Holz hergestellte Leistenträger 2 mit Hilfe von Schrauben 3 und Muttern 4 festgespannt. Die motorisch angetriebenen, sich um die Achse 5 drehenden Rollen 6 verschieben das Werkstück 7 auf den, sich im Querschnitt darstellenden, auf dem Leistenträger 2 befestigten Leisten 8, in Richtung dieser Leisten. Das sich um die Achse 9 drehende Kreissägenblatt io schneidet das Werkstück 7 in zwei Teile.In the drawing, an embodiment is shown schematically in cross section shown. On the machine table i is the board-shaped one made of wood Strip carrier 2 clamped with the help of screws 3 and nuts 4. The motor driven rollers 6 rotating around the axis 5 move the workpiece 7 on the, shown in cross section, attached to the strip carrier 2 Strips 8, in the direction of these strips. The circular saw blade rotating around the axis 9 io cuts the workpiece 7 into two parts.

Die Leisten werden am besten aus Stahl oder Leichtmetall gefertigt. Sie sollen härter als das Werkstück sein. Ihre Anzahl richtet sich nach Größe und Verwendungsbereich der Holzbearbeitungsmaschine.The strips are best made of steel or light metal. They should be harder than the workpiece. Their number depends on size and Area of use of the woodworking machine.
