KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Eine zeitraubende und daher kostspielige Arbeit bei der Herstellung von Zapfenbändern, Betthaken und dergl. bestand bisher darin, daß die zur Aufnahme der Schrauben dienenden Löcher einzeln gestanzt und hierauf einzeln versenkt werden mußten.A time-consuming and therefore costly job in the manufacture of tenon hinges, Bed hooks and the like. Previously consisted in the fact that the screws Serving holes punched individually and then had to be sunk individually.
Gegenstand der vorliegenden Erfindung ist eine Maschine, welche beide Arbeitsvorgänge in sich vereinigt und selbst bei dicht nebeneinander liegenden Schraubenlöchern das gleichzeitige Versenken mehrerer Löcher ermöglicht. . Die Erfindung ist in beiliegender Zeichnung zur Darstellung gebracht, und zwar zeigtThe present invention is a machine that does both operations united in itself and, even if the screw holes are close together, the same Allows countersinking of several holes. . The invention is shown in the accompanying drawing brought to the display, namely shows
Fig. ι die Maschine in Aufsicht,
Fig. 2 und 3 die Einrichtung zum Versenken der Löcher undFig. Ι the machine in plan,
Fig. 2 and 3 the device for countersinking the holes and
Fig. 4 ein Zapfenband mit eingestanzten Löchern.4 shows a pivot hinge with punched holes.
Auf einem Tisch α ist eine Matrize b und eine Presse c angeordnet, die zum Einstanzen der Löcher in das Metallband M, welches als endloses, gerichtetes Band der Maschine zugeführt wird, dient.A die b and a press c are arranged on a table α , which are used to punch the holes in the metal band M, which is fed to the machine as an endless, straightened band.
Die zum Versenken der gestanzten Löcher dienende Einrichtung ist folgende:The device used to countersink the punched holes is as follows:
Auf einem Schlitten d, welcher durch eine Zugstange e und einen Hebel f mit einem Excenter g verbunden ist, ist ein Lager h angebracht, welches mit einem horizontalen Führungsschlitz h1 versehen ist, in welchem Schraubenbolzen ρ angeordnet sind, an welche mittels ösen q Bohrspindeln i angehängt sind; letztere können in vertikaler Richtung verstellt werden, während durch Verschieben der Schraubenbolzen in dem Schlitz hl eine horizontale Verstellung der Bohrspindeln ermöglicht wird. Die Bohrspindeln werden durch Kugelgelenkstangen /, Räder m und Riemsch'eiben η angetrieben.On a slide d, which is connected to an eccentric g by a tie rod e and a lever f , a bearing h is attached, which is provided with a horizontal guide slot h 1 in which screw bolts ρ are arranged, to which drilling spindles by means of eyelets q i are appended; the latter can be adjusted in the vertical direction, while a horizontal adjustment of the drilling spindles is made possible by moving the screw bolts in the slot h l. The drilling spindles are driven by ball joint rods /, wheels m and pulleys η .
Durch das Exzenter g wird der Schlitten d und damit die Bohrer k vor das von der Matrize weiter vorgeschobene Band M gebracht, wobei die Bohrer die vor ihnen liegenden Löcher versenken. Nachdem dies ' geschehen, wird durch das Exzenter der Schlitten wieder von dem Band zurückgeschoben , dieses freigegeben und selbsttätig weiter vorgeschoben.By means of the eccentric g , the slide d and thus the drill k are brought in front of the band M advanced further by the die, the drill sinking the holes in front of them. After this has happened, the eccentric pushes the carriage back from the belt, releases it and automatically pushes it forward.
Hinter der Versenkvorrichtung ist eine Schere 0 angeordnet, welche in bekannter Weise das aus der ersteren austretende Band auf bestimmte Länge abschneidet. Je nach der erforderlichen Länge wird die Zuführung des Bandes geregelt, so daß immer so viel Bandmaterial zugeführt wird, als die Schere abschneidet.Behind the lowering device a pair of scissors 0 is arranged, which in known Way, the band emerging from the former is cut to a certain length. Depending on the required length, the feed of the tape is regulated, so that always so much Tape is fed as the scissors cut.
Bei eng aneinander liegenden, zu versenkenden Löchern werden die Bohrspindeln i derart eingesetzt, daß die Bohrer nicht zwei nebeneinander liegende Löcher gleichzeitig versenken, sondern je eins überspringen, welche dann beim nächsten Vorschub versenkt werden; Fig. 4 veranschaulicht diesen Vorgang, a1 ist. ein Band, in welches die Löcher für vier Zapfenbänder eingestanzt sind, bl sind die Zapfenlöcher, welche nicht versenkt werden, cl und d1 sind die zu versenkenden Löcher, und zwar werden immer zwei Löcher c1 und dann zwei Löcher d1 gleichzeitig versenkt.In the case of holes to be countersunk close to one another, the drilling spindles i are used in such a way that the drills do not countersink two adjacent holes at the same time, but rather skip one each, which is then countersunk at the next feed; Fig. 4 illustrates this process, a is 1 . a band in which the holes for four tenon hinges are punched, b l are the tenon holes which are not countersunk, c l and d 1 are the holes to be countersunk, namely always two holes c 1 and then two holes d 1 at the same time sunk.
Claims (1)
Eine Maschine zum gleichzeitigen Stanzen und Versenken von Löchern in Zapfenbändern und dergl., dadurch gekennzeichnet, daß das absatzweise vorgeschobene Metallband (M) zuerst von einer Stanze (C) gelocht wird und dann die Löcher in demselben von dahinter liegenden, in einem beweglichen Schlitten (d) verstellbar gelagerten Bohrern (k) versenkt werden, worauf das Band von einer Schere (o) abgeschnitten wird.Patent claim:
A machine for the simultaneous punching and countersinking of holes in tenon hinges and the like, characterized in that the metal strip (M) , which is advanced in steps, is first punched by a punch (C) and then the holes in the same from behind it, in a movable slide ( d) adjustable drill bits (k) are sunk, whereupon the tape is cut off by scissors (o).
