Description
Den Gegenstand der Erfindung bildet ein als tragbare Metallsäge ausgebildetes Preßluftwerkzeug, dessen Sägeblatt an der hin und her gehenden Kolbenstange eines Preßlufthandhammers befestigt ist und durch diesen angetrieben wird. Derartige Vorrichtungen werden hauptsächlich zum Sägen von Rohren, Proiileisen, Grubenstempeln u. dgl. benutzt, bei denen es auf eine rasche und saubere Arbeit ankommt, die dadurch beeinträchtigt wird, daß die Bedienungsperson die ganzen sowohl der Zahl als auch der Größe nach sehr erheblichen Stoßkräfte des Werkzeuges aufnehmen muß, dabei aber gleichzeitig auf die Führungen der Säge in der Schnittebene achten und für einen ausreichenden Vorschub Sorge tragen muß. Die vorliegende Erfindung erleichtert diese Arbeiten durch eine an der tragbaren Hammersäge angeordnete Vorrichtung, bei der das Gehäuse des Preßlufthandhammers in der Sägeblattebene drehbar auf einem Rahmen (Grundplatte) gelagert ist, auf der gleichzeitig auch die Spannvorrichtung für das Werkstück angebracht ist. Dadurch wird eine Entlastung der Bedienungsperson von den schlagartig aufeinanderfolgenden Stoßkräften des Werkzeuges erreicht, diese Kräfte werden in einem in sich geschlossenen System aufgenommen, welches das Werkzeug in der Schnittebene führt und vorschiebt.The subject of the invention is a compressed air tool designed as a portable hacksaw, its saw blade on the reciprocating piston rod of a pneumatic hand hammer is attached and is driven by this. Such devices are mainly used for sawing Pipes, profile irons, pit punches and the like are used where there is a need for a quick and clean work arrives, which is affected by the fact that the operator the In terms of both number and size, the impact forces of the tool are very considerable must take up, but at the same time pay attention to the guides of the saw in the cutting plane and for a sufficient Feed must take care. The present invention facilitates this work by means of an arranged on the portable hammer saw Device in which the housing of the pneumatic hand hammer can be rotated in the plane of the saw blade on a frame (base plate) is stored, on which the clamping device for the workpiece is attached at the same time is. This relieves the operator of the suddenly successive impact forces of the tool achieved, these forces are absorbed in a self-contained system, which guides and advances the tool in the cutting plane.
Drehbare Lagerungen sind zwar für Sägeantriebe bekannt. Dort handelt es sich jedoch um ohne Schlagwirkung arbeitende Antriebe, welche von einer umlaufenden Welle eines gleichzeitig einen Bohrerkopf antreibenden Elektromotors ausgehen, der für kleine Reparaturarbeiten, wie Bohren, Feilen, Sägen u. dgl., an einem Maschinenständer schwingend befestigt ist. Solche nur für kleine Leistung'en dienenden Antriebswerkzeuge haben keine Schlagwirkung und dürfen einer solchen schon wegen der schwingenden Zahnsegmente im Antrieb nicht ausgesetzt werden. Außerdem ist die hängende Lagerung des Werkzeuges an einem, aufragenden Rohr den Erschütterungen eines Preßlufthammerbetriebes nicht gewachsen und würde demgemäß keine saubere Schnittarbeit ergeben. Rotatable bearings are known for saw drives. There it is, however to drives working without impact, which are driven by a rotating shaft of a at the same time an electric motor driving a drill head goes out, which is used for small repair work, such as drilling, filing, sawing and the like, swinging on a machine stand is attached. Such drive tools, which are only used for small capacities, have no impact and are allowed to do so because of the vibrating tooth segments are not exposed in the drive. In addition, the hanging storage of the tool is on an upright Pipe the vibrations of a jackhammer factory not grown and accordingly would not result in a clean cut.

An der im Arbeitszylinder 20 undrehbar geführten Kolbenstange 1 ist eine Säge befestigt,
deren Bügel mit 2 und deren BIa; mit 4 bezeichnet ist. Der Arbeitszylinder_2jjj
hat auf jeder Seite einen Tragzapfen 21;
diesen Tragzapfen ist der Zylinder 20 unt Vermittlung eines Bockes 22 an einem rah~-
menartigen Traggestell 23 gelagert. Jeder Tragzapfen 21 greift in eine einseitig offene
Aussparung 24 des Bockes ein, die an der offenen Seite durch einen Querstift 25 verschließbar
ist. Der Bock ist am Traggestell 23 mit Schrauben 26 befestigt, die in Schlitze 27 eingreifen, so daß der Bock, wenn die
Schrauben 26 gelöst sind, dem Traggestell gegenüber verschiebbar ist. An dem dem
Bock 22 abgekehrten Ende ist der Rahmen 23 mit einer Festspannvorrichtung nach Art
eines Parallelschraubstockes versehen. Mit 28 ist die eine feste Backe, mit 29 die andere
bewegliche Backe und mit 30 die Spannspindel bezeichnet. Diese Teile sitzen unter Vermittlung
eines abgeschrägten Führungsteiles 31 derart am Rahmen 23, daß die Druckflächen
der Backen 28, 29 der Festspannvorrichtung in der Bewegungsebene der Säge zur Bewegungsrichtung der Säge geneigt sind, so
daß die Säge, wenn diese ihren Schnitt beginnt, zunächst nicht in eine Seite, sondern
in eine Kante eines Werkstückes von rechteckigem oder ähnlichem Querschnitt einschneidet.
Im Rahmen 23 liegt eine schraubenförmige Zugfeder 32, deren eines Ende
durch eine Hakenschraube 33 mit zugehöriger Flügelmutter 34 nachstellbar am Rahmen
23 befestigt ist, während am anderen Ende ein Seil 35 angreift, das über eine Rolle 36
zu einem am Arbeitszylinder 20 sitzenden Haken 37 führt. Durch Drehen der Flügelmut ter
34 läßt sich der Druck, mit dem sich die Säge 2, 4 gegen das Werkstück 38 legt, verändern.
Damit die Vorrichtung leicht am Werkstück angebracht werden kann oder umgekehrt,
ist folgende Einrichtung vorgesehen: Am Rahmen 23 sitzt ein Lagerstück 39, an
das eine Stütze 40 angelenkt ist, die sich bei der in der Zeichnung mit ausgezogenen Linien
dargestellten Lage gegen den Arbeitszylinder 20 legt und dadurch die Säge so festhält, daß
diese das Hineinbringen des Werkstückes in die Einspannvorrichtung nicht hindert. Beim
Ingangsetzen der Säge wird die Stütze 40 in die in der Zeichnung strichpunktiert dargestellte
Lage geklappt. Wenn der Schnitt :ndet ist, dient das Lagerstück 39 als Auilag
für den Arbeitszylinder 20 und verhindert damit, daß die Säge 2, 4 in das Traggestell
einschneidet.A saw is attached to the piston rod 1, which is non-rotatably guided in the working cylinder 20, and its bracket is marked with 2 and its BIa; is denoted by 4. The working cylinder_2jjj has a support pin 21 on each side;
The cylinder 20 is mounted on this support pin by means of a bracket 22 on a frame-like support frame 23. Each support pin 21 engages in a recess 24 of the bracket, which is open on one side and which can be closed on the open side by a transverse pin 25. The bracket is attached to the support frame 23 with screws 26 which engage in slots 27 so that the bracket, when the screws 26 are loosened, can be displaced with respect to the support frame. At the end facing away from the bracket 22, the frame 23 is provided with a clamping device in the manner of a parallel vice. With 28 one fixed jaw, with 29 the other movable jaw and with 30 the clamping spindle. These parts sit with the mediation of a beveled guide part 31 on the frame 23 in such a way that the pressure surfaces of the jaws 28, 29 of the clamping device are inclined in the plane of movement of the saw to the direction of movement of the saw, so that the saw when this begins its cut, initially not in one side, but cuts into an edge of a workpiece of rectangular or similar cross-section. In the frame 23 there is a helical tension spring 32, one end of which is fastened to the frame 23 in an adjustable manner by a hook screw 33 with associated wing nut 34, while a rope 35 engages at the other end, which leads via a roller 36 to a hook 37 seated on the working cylinder 20 . By turning the wing nut 34, the pressure with which the saw 2, 4 lays against the workpiece 38 can be changed. So that the device can easily be attached to the workpiece or vice versa, the following device is provided: A bearing piece 39 sits on the frame 23, to which a support 40 is articulated, which lies against the working cylinder 20 in the position shown in the drawing with solid lines and thereby holding the saw so that it does not prevent the workpiece from being brought into the jig. When starting the saw, the support 40 is folded into the position shown in dash-dotted lines in the drawing. When the cut has been made, the bearing piece 39 serves as a support for the working cylinder 20 and thus prevents the saw 2, 4 from cutting into the support frame.
Wie mit der Vorrichtung gearbeitet wird, ergibt sich an Hand des vorstehenden für den Fachmann von selbst. Es hängt von den Umständen ab, ob die Vorrichtung an das Werkstück herangebracht bzw. auf dieses aufgeschoben wird, oder umgekehrt.How to work with the device results from the above for the Expert by himself. It depends on the circumstances whether the device is attached to the workpiece is brought up or pushed onto this, or vice versa.
