Abstract

Threaded bars can be cut to length without obligatory post-machining of the thread-way, using a recess in the shear-off arm (1) for the initial addressing movement in the first stage followed by cut completion in the second stage. The cutters (14) are exchangeable in the tongs which can handle a wide range of thread sizes and minimise the manual force required for the lengthening due to the use of cylindrical positioning pins (B) and the recess provided in the pressure arm (3). The pressure arm (3) is moved away from arm (1) so pin (B) sets to position (E) with the tongs thus opening as underside (2) moves right. The tongs are placed at cut point (D) so when the arm (3) is pressed onto arm (1) the cutters (14) are addressed in front of the thread and so, as slide (2) runs back onto its stop screws, the tongs are pre-tensioned and clamped in place. Pin (B) moves to position (A) so that repeat pressing of the arms performs the lengthening operation.

Description

Es ist bekannt, Gewindestangen mit Werkzeugen oder Geräten wie: Sägen, Schleif­ hexen, Bolzenschneidern, Feilen, Rohrschneidern abzulängen.It is known to use threaded rods with tools or equipment such as: sawing, grinding cut witches, bolt cutters, files, pipe cutters.

Der im Patentanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, daß bei den bekannten Verfahren ein Nacharbeiten des geschnittenen Gewindes not­ wendig ist, oder aufwendige Maschinen verwendet werden müssen.The invention specified in claim 1 is based on the problem that in the known methods, reworking of the cut thread is not necessary is maneuverable, or complex machines have to be used.

Diese Probleme werden durch die im Patentanspruch 1 aufgeführten Merkmale gelöst.These problems are solved by the features listed in claim 1 solved.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß ein auf­ wendiges Nacharbeiten des geschnittenen Gewindes nicht mehr nötig ist, sondern die bearbeiteten Gewindestangen sofort ihrer Weiterverarbeitung zugeführt werden können. Ferner ist durch die relativ kleine Bauweise, das leichte Gewicht und die einfache Handhabung der Zange ein Werkzeug entstanden, welches sich in jeglicher Arbeitslage (z. B. auf einer Leiter) auszeichnet. Die Konstruktion der Zange ermöglicht die Minimierung der Handkraft. Die leichte Auswechselbarkeit der Schneidmesser ermöglicht den Einsatz des Werkzeuges bei verschiedenen Größen von Gewinde­ stangen.The advantages achieved by the invention are in particular that a agile reworking of the cut thread is no longer necessary, but the machined threaded rods are immediately fed for further processing can. Furthermore, due to the relatively small construction, the light weight and the easy handling of the pliers created a tool that can be found in any Working position (e.g. on a ladder). The design of the pliers enables minimizing hand strength. The easy interchangeability of the cutting knives enables the use of the tool with different sizes of thread rods.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is in following described in more detail.

Das Werkzeug befindet sich auf der beigelegten Zeichnung im geschlossenem Zu­ stand, das heißt, der Schneidvorgang ist beendet. The tool is in the closed drawing on the enclosed drawing stood, that is, the cutting process is finished.  

Das Werkzeug wird geöffnet, indem der Druckhebel 3 entgegen dem Hebel vom Scherarm 1 bewegt wird und der Führungsstift B des Druckhebels an der Stelle E positioniert wird. Der Unterschlitten 2 bewegt sich nach rechts, das Werkzeug ist geöffnet.The tool is opened by moving the pressure lever 3 against the lever by the shear arm 1 and positioning the guide pin B of the pressure lever at point E. The lower carriage 2 moves to the right, the tool is open.

Das Werkzeug wird an der Stelle D an der Stelle der Gewindestange positioniert, wo der Schnitt durchgeführt werden soll.The tool is located at location D at the location of the threaded rod positioned where the cut should be made.

Durch drücken des Druckhebels 3 gegen den Scherarm 1 werden die Schneidmesser 14 vor die Gewindestange angedrückt. Der Unterschlitten bewegt sich gegen die Anschlagschrauben. Das Werkzeug ist vorgespannt.By pressing the pressure lever 3 against the shear arm 1 , the cutting knives 14 are pressed in front of the threaded rod. The lower carriage moves against the stop screws. The tool is preloaded.

Durch positionieren des Stiftes B an der Stelle A und erneutes drücken des Hebels 3 gegen den Scherarm 1 wird die Scherkraft eingeleitet und die Gewindestange getrennt. Der Arbeitsvorgang ist abgeschlossen.By positioning the pin B at point A and pressing the lever 3 again against the shear arm 1 , the shear force is introduced and the threaded rod is separated. The process is complete.

Das Auswechseln der eingesetzten Schneidmesser (M4-M12) erfolgt durch herausdrehen der Innensechskantschrauben 9 und anschließendem auswechseln der Schneidmesser.The cutting blades used (M4-M12) are replaced by unscrewing the Allen screws 9 and then changing the cutting blades.
