Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Gegenstand vorliegender Erfindung bildet . eine Maschine zur Herstellung von Gehrungsausschnitten an Türfriesen u. dgl. Forms the subject of the present invention. a machine for the production of miter cutouts on door friezes and the like.

Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung veranschaulicht, und zwar zeigt Fig. ι die Ansicht und Fig. 2 den Grundriß der Maschine. Wie Fig. 1 zeigt, sind auf zwei unter einem Winkel von 45 ° zum Werkstück gelagerten Wellen α und Ci1 je zwei in ihren Durchmessern verschieden große Kreissägen b und I1 so angeordnet, daß die vier oberen Schnittkanten in eine Schnittebene x-x fallen. Über diesen Sägepaaren, die durch Abstandsringe c und C1 auseinandergehalten werden, ist eine dritte Welle a3 mit einer kleineren Kreissäge b2 so gelagert, daß die Ebene, in der diese Kreissäge liegt, die Kreise der .Sägen b und bx tangiert, wie Fig. 1 zeigt.An exemplary embodiment of the invention is illustrated in the drawing, namely FIG. 1 shows the view and FIG. 2 shows the plan view of the machine. As FIG. 1 shows, two circular saws b and I 1 of different diameters are arranged on two shafts α and Ci 1 mounted at an angle of 45 ° to the workpiece so that the four upper cutting edges fall into a cutting plane xx. Above these pairs of saws, which are kept apart by spacer rings c and C 1 , a third shaft a 3 with a smaller circular saw b 2 is mounted in such a way that the plane in which this circular saw lies touches the circles of the saws b and b x, as Fig. 1 shows.

Der Arbeitsvorgang beim Schneiden selbst ist folgender:The process of cutting itself is as follows:

Nachdem die Zapfenlöcher d (Fig. 3) hergestellt sind, wird das Arbeitsstück, das den Gehrungsausschnitt erhalten soll, auf einem horizontal beweglichen Schlitten vorgeschoben. Das Arbeitsstück wird nunmehr in die Schnittzone der vier Sägeblätter gebracht, und es entstehen dadurch vier Gehrungseinschnitte elt S2, e3, et (Fig..ι und 4).After the mortises d (Fig. 3) are made, the work piece that is to receive the miter cut is advanced on a horizontally movable carriage. The work piece is now brought into the cutting zone of the four saw blades, and this results in four miter cuts e lt S 2 , e 3 , e t (FIGS. 1 and 4).

Ist das Arbeitsstück in der punktierten Stellung 0-0 (Fig. 2) angelangt, so hat die kleinere Säge b2 die vordere Wange f (Fig. 3) zwischen Gehrungseinschnitt e2 und es durchschnitten, so daß der in Fig. 4 schraffierte Holzteil g herausfällt. Durch weiteren Vorschub des Arbeitsstückes wiederholt sich der Arbeitsvorgang an der Wange f1 (Fig. 3), und es entsteht dadurch ein freier Durchgang für die Welle a3, wodurch gleichzeitig die beiden restlichen Teile'gx und g2 (Fig. 4) entfernt werden und somit ein vollständiger Gehrungsausschnitt entsteht.If the workpiece has reached the dotted position 0-0 (FIG. 2), the smaller saw b 2 has cut through the front cheek f (FIG. 3) between the miter cut e 2 and e s , so that the hatched in FIG Part of wood g falls out. By further advancing the workpiece, the work process is repeated on the cheek f 1 (Fig. 3), and this creates a free passage for the shaft a 3 , whereby the two remaining parts g x and g 2 (Fig. 4) can be removed and a complete miter cut is created.

Claims (1)

Patent-Anspruch:Patent claim: Gehrungsschneidemaschine mit winklig zueinander stehenden Kreissägen, insbesondere zur Herstellung von Ausschnitten mit bereits vorgearbeitetem Zapfloch, dadurch gekennzeichnet, daß das mit dem Gehrungsausschnitt zu versehende Werkstück durch je zwei auf zwei sich schneidenden Achsen (a, Ci1) angeordnete parallele Sägeblätter (b, B1), von denen die beiden äußersten die Form des Ausschnittes bestimmen, zuerst quer durchschnitten wird, worauf durch eine tangential zu den beiden Kreissägepaaren (b, δα) liegende horizontale Kreissäge (S2) zuerst der Ausschnitt zwischen den beiden innersten Sägeblättern zwecks Schaffung eines Durchganges für die Drehachse (a3) der Kreissäge und bei weiterem Vorschub derselben erst die äußeren Teile entfernt werden.Miter cutting machine with circular saws at an angle to one another, in particular for the production of cutouts with already prepared mortise, characterized in that the workpiece to be provided with the miter cut is provided by two parallel saw blades (b, B 1 ) each arranged on two intersecting axes (a, Ci 1) ), of which the two outermost ones determine the shape of the cut-out, first cut transversely, whereupon the cut-out between the two innermost saw blades is first created using a horizontal circular saw (S 2 ) tangential to the two pairs of circular saws (b, δ α) Passage for the axis of rotation (a 3 ) of the circular saw and with further advance of the same only the outer parts are removed.
