Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Gewöhnlich wird zwecks Herstellung krummliniger Schnitte die gewünschte Kurve jedesmal besonders auf das Werkstück aufgezeichnet und dieses dann ohne Führungsvorrichtungen dem Werkzeug entgegengeführt. Nur für geradlinige und kreisförmige Schnitte waren zeitsparende Hilfsvorrichtungen allgemein in Gebrauch.Usually, in order to make curvilinear cuts, the desired curve is made every time especially recorded on the workpiece and this then without guiding devices towards the tool. Were only for straight and circular cuts time-saving auxiliaries in common use.

Die vorliegende Erfindung bezweckt, dasThe present invention aims that

ίο jedesmalige Aufzeichnen der Kurve und die peinliche Sorgfalt beim Schneiden längs dieser Kurve entbehrlich zu machen.ίο every time recording the curve and the to dispense with painstaking care when cutting along this curve.

Es gibt allerdings schon einige Anordnungen zur Erreichung dieses Zweckes.However, there are already some arrangements to achieve this.

Abgesehen von Vorrichtungen für Spezialzwecke, ζ. Β. zur Herstellung kurzer geradliniger Nuten für Fensterbeschläge (nur für Fräser brauchbar), gibt es Anordnungen, die die Aufgabe in ihrer Allgemeinheit zu lösen versuchen.Except for special purpose devices, ζ. Β. for making short straight lines Grooves for window fittings (only usable for milling cutters), there are arrangements that solve the task in general try.

Die eine derselben verschiebt und verdreht das Sägeblatt entsprechend einer Leitkurve, welche auf dem Werkstück angebracht ist, und gibt diesem beim Vorschub eine Führung mit Hilfe einer zweiten feststehenden Leitkurve. Die hiermit verbundene Beanspruchung des Sägeblattes erscheint bedenklich, um so mehr, als es zugleich zur Führung des Werkstückes herangezogen wird.One of them moves and rotates the saw blade according to a guide curve, which is attached to the workpiece and gives it a guide as it is advanced with the help of a second fixed guide curve. The associated stress the saw blade appears questionable, all the more so as it is also used to guide the workpiece is used.

Diesen Fehler vermeidet die zweite Anordnung, welche das Werkstück dem freilaufenden Sägeblatt mit Hilfe zweier Leitkurven entgegenführt. Diese Anordnung zeigt mit der vorliegenden einige Ähnlichkeit. Ein wesentlicher Unterschied besteht aber darin, daß beim Erfindungsgegenstand die eine der beiden Führungskurven durch das Sägeblatt geht, wobei durch die konstruktive Anordnung erreicht wird, daß dieses selbst frei von zusätzlichen Spannungen bleibt. ■ Hierdurch wird eine einfachere Ausbildung, eine bequemere Herrichtung für jeden einzelnen Fall und eine vielseitigere Verwendungsmöglichkeit erzielt.This error avoids the second arrangement, which the workpiece to the free-running Saw blade with the help of two guide curves. This arrangement shows with some resemblance to the present one. A key difference is that that in the subject matter of the invention, one of the two guide curves through the saw blade goes, which is achieved by the structural arrangement that this itself is free of additional tension remains. ■ This makes training easier and more convenient Preparation for each individual case and a more versatile use achieved.

Die beiliegenden Zeichnungen veranschauliehen ein Ausführungsbeispiel der Erfindung.The accompanying drawings illustrate an embodiment of the invention.

Es ist angenommen, es soll auf der Bandsäge in ein Brett die gezeichnete Kurve eingeschnitten werden. Das Werkstück ist auf einen Schlitten gespannt. In diesem ist ein Schlitz b b eingearbeitet, dessen Mittellinie mit der gewünschten Schnittkurve zusammenfällt. Vermittels dieses Schlitzes gleitet der Schlitten an einem Bolzen c des Maschinentisches entlang. Die Achse des Bolzens c liegt im Sägeblatt. Am Ende des Schlittens ist ein Bolzen d befestigt. Dieser gleitet in einem Schlitz ee, welcher in den Tisch eingearbeitet ist. Die Form der Schlitze ist derart gewählt, daß erstens die Relativbewegung zwischen Sägeblatt und Werkstück längs der gewünschten Schnittkurve erfolgt, zweitens das Sägeblatt stets tangential zu dieser Kurve steht.It is assumed that the curve drawn is to be cut into a board on the band saw. The workpiece is clamped on a slide. In this a slot bb is incorporated, the center line of which coincides with the desired intersection curve. By means of this slot, the carriage slides along a bolt c of the machine table. The axis of the bolt c lies in the saw blade. A bolt d is attached to the end of the slide. This slides in a slot ee which is worked into the table. The shape of the slots is chosen such that, firstly, the relative movement between the saw blade and workpiece takes place along the desired cutting curve, and secondly, the saw blade is always tangential to this curve.

Derselbe Gedanke, Führung des Werk-Stückes durch zwei Kurven, läßt sich auch derart zur Ausführung bringen, daß man beide Kurven in den Schieber legt und den Bolzen d in den Tisch einschraubt.The same idea of guiding the work piece through two curves can also be carried out by placing both curves in the slide and screwing the bolt d into the table.
