PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung betrifft eine Metallkaltsäge, bei der das Abheben des Sägeblattes von der Schnittstelle dadurch in einfachster Weise erreicht wird, daß das Sägeblatt am Ende des Arbeitsganges durch Anschlagen des Schlittens an einen Bolzen Schienen mitnimmt, welche mittels Bolzen in Schrägnuten der Schlittenführung eingreifen und letztere so verschieben, daß dasThe present invention relates to a metal cold saw, in which the lifting of the saw blade from the interface is very easy Way is achieved that the saw blade at the end of the operation by striking of the slide takes along rails on a bolt, which engage in inclined grooves of the slide guide by means of bolts and move the latter so that the
ίο Sägeblatt von der Schnittstelle entfernt wird.ίο The saw blade is removed from the interface.
Am Ende des Leerhubes werden die Schienen in umgekehrter Richtung bewegt und das Blatt der Schnittstelle wieder nahe gebracht.At the end of the idle stroke, the rails are moved in the opposite direction and that Leaf brought back close to the interface.
In Fig. I, 2, 3 und 4 ist eine Ausführungsform dargestellt, bei welcher das Abheben des Sägeblattes von der Schnittstelle durch eine solche Einrichtung erfolgt. In dem Gehäuse g ist die Führung h für den das Blatt α tragenden Schlitten i gelagert, der durch eine in Fig. 1 und 3 strichpunktiert angedeutete Kreisbewegung eines Exzenters oder einer Kurbel auf- und abbewegt wird.In Fig. I, 2, 3 and 4, an embodiment is shown in which the lifting of the saw blade from the interface is carried out by such a device. The guide h for the slide i carrying the sheet α is mounted in the housing g and is moved up and down by a circular movement of an eccentric or a crank, indicated by dash-dotted lines in FIGS. 1 and 3.
In der Gehäusewand g sind die beiden nur in ihrer Längsrichtung verschiebbaren Schienen k gelagert, welche durch den Bolzen Z fest miteinander verbunden sind. Die Schienen k tragen an ihren oberen Enden je einen kurzen Bolzen m, welcher nur durch die Führung h reicht. Die Bolzen Z. und m greifen in schräge Schlitze η dieser Führung h. In dem Schlitten befindet sich ferner ein Schlitz 0, durch welchen der Bolzen I hindurchgeht, um eine Bewegung der Schiene k gegen die Führung h zu gestatten. Am Ende der jedesmaligen Schlittenbewegung schlägt das obere Ende des Schlitzes 0 auf den Bolzen /, verschiebt damit die Schienen k, wodurch wiederum die Führung h infolge der schrägen Nuten η quer zu den Schienen k und dem Gehäuse g verschoben wird. Es wird also der Schlitten i in seiner tiefsten Stellung durch Anschlagen an den Bolzen I das Sägeblatt von der Schnittstelle abheben. Am Ende des Aufwärtsganges schlägt der Schlitten mit dem unteren Ende des Schlitzes 0 wieder gegen den Bolzen / und schiebt dadurch das Sägeblatt wieder an die Schnittstelle an. The two rails k , which can only be displaced in their longitudinal direction and are firmly connected to one another by the bolt Z, are mounted in the housing wall g. The rails k each have a short bolt m at their upper ends, which only extends through the guide h. The bolts Z. and m engage in oblique slots η of this guide h. In the carriage there is also a slot 0 through which the bolt I passes to allow movement of the rail k against the guide h . At the end of each slide movement, the upper end of the slot 0 hits the bolt /, thereby shifting the rails k, which in turn shifts the guide h as a result of the inclined grooves η transversely to the rails k and the housing g . The carriage i will therefore lift the saw blade from the interface in its lowest position by striking the bolt I. At the end of the upward gear, the carriage hits the lower end of the slot 0 again against the bolt / and thereby pushes the saw blade back to the interface.
Der notwendige Vorschub der Säge erfolgt in üblicher Weise durch eine Schraubenspindel. Der Antrieb der Säge kann durch eine Kulisse oder auch in anderer Art, etwa durch Daumenhebel und Rückführung des Schlittens durch Feder und Gegengewicht erfolgen. The necessary advance of the saw is carried out in the usual way by a screw spindle. The drive of the saw can be through a backdrop or in some other way, such as thumb lever and return of the Slide made by spring and counterweight.
