Die Erfindung betrifft eine Schweißvorrichtung, bestehend aus einer von Hand zu haltenden Schweißzange mit Schaltvorrichtung für eine Schweißstromquelle und einer am Kopf des Schweißers befestigbaren Schutzhaube mit beweglich gelagertem Dunkelsichtglas.The invention relates to a welding device consisting of a welding gun to be held by hand with a switching device for a welding current source and a protective hood which can be fastened to the head of the welder and has movably mounted dark glass.
Zum Schutz bei Schweißarbeiten mit einer von Hand zu haltenden Schweißzange ist es bekannt, eine Schutzhaube zu benutzen, die vor das Gesicht des Schweißers gehalten wird, wenn dieser arbeitet. Die Schutzhaube weist ein Dunkelsichtglasfenster auf, das dem Schweißer erlaubt, die Schweißarbeit zu beobachten, ohne daß die Augen durch grelles Blitzlicht geschädigt werden. Es sind auch Schutzhauben bekannt, bei denen das Dunkelsichtglas abklappbar angeordnet ist.To protect welding work with a handheld welding gun, it is known to use a protective hood that is held in front of the welder's face when he is working. The protective hood has a dark glass window, which allows the welder to observe the welding work without the eyes being damaged by flashy flashing light. Protective hoods are also known in which the dark viewing glass is arranged such that it can be folded down.
Bei den bekannten Vorrichtungen ist nachteilig, daß nicht gesichert ist, daß der Schweißer nur dann schweißt, wenn seine Augen gegen helle Blitzstrahlen abgeschirmt sind. Aufgabe der Erfindung ist es daher, eine Schweißvorrichtung vorzuschlagen, die derart ausgebildet ist, daß bei aufgesetzter Schutzhaube vor Einschalten derA disadvantage of the known devices is that it is not ensured that the welder only welds when his eyes are shielded from bright lightning rays. The object of the invention is therefore to propose a welding device which is designed such that when the protective hood is in place before switching on
Schwei ßstromqe l le das Dunkelsichtglas der Schutzhaube sicher als Augenschutz dient.Welding current, the dark glass of the protective hood serves as eye protection.
Die Aufgabe wird bei einer Schweißvorrichtung der eingangs genannten Art dadurch gelöst, daß das Dunkels chtglas an der Innenwandung der Schutzhaube verschiebbar gelagert und mit einer Rückholfeder verbunden ist, die über eine Antriebsvorrichtung mit der Schaltvorr chtung für die Schwei ßstromqelle wirksam verbunden ist.The object is achieved in a welding device of the type mentioned in that the dark glass is slidably mounted on the inner wall of the protective hood and is connected to a return spring which is connected via a drive device with the switching device for the welding current source.
Vorteilhaft ist das Dunkelsichtglas parallel zu einem in der Schutzhaube angeordneten Sichtfenster angebracht und in seitlichen Führungsprofilen geführt.The dark viewing glass is advantageously mounted parallel to a viewing window arranged in the protective hood and guided in lateral guide profiles.
Die Rückholfeder ist vorzugsweise einsei ig mit einem Steuerhebel verbunden. Der Steuerhebel ist nach einer vorte lhaften Ausführungsform mit einem Zugmagnet verbunden, der entgegen der Federkraft der Rückholfeder wirksam ist und der durch einen Ein- Aus-Mi kroscha Iter einer Schweißzange betätigbar ist.The return spring is preferably connected to a control lever on one side. The control lever is connected according to an advantageous embodiment with a pull magnet, which is effective against the spring force of the return spring and which can be actuated by an on-off microswitch of a welding gun.
Nach einer anderen Ausführungsform ist der Steuerhebel als Wipphebel ausgebildet und einseitig über einen Bowdenzug mit einem Schalter der an der Schweißzange angeordneten Schaltvorrichtung wirksam verbunden.According to another embodiment, the control lever is designed as a rocker arm and is effectively connected on one side via a Bowden cable to a switch of the switching device arranged on the welding gun.
Die Schaltvorrichtung weist vorteilhaft im Abstand voneinander Kontakte für die Stromzuführung der Schweißzange und für die Betätigung der Rückholfeder des Dunkelsichtglases auf und die Kontakte sind unabhängig voneinander durch ein gemeinsames, verschiebbares Betätigungsorgan derartig betätigbar, daß bei eingeschalteter Stromzufuhr das Dunke l si chtg las das Sichtfenster abdeckt.The switching device advantageously has contacts at a distance from one another for the power supply of the welding gun and for the actuation of the return spring of the dark glass, and the contacts are independent can be actuated from one another by a common, displaceable actuating member in such a way that when the power supply is switched on, the darkness reads the viewing window.
Das Betätigungsorgan der Schaltvorrichtung ist nach einer vortei lhaften Aus ührungsform entlang einer winklig abgeknickten Zeitverzögerungsbahn geführt.The actuator of the switching device is guided according to an advantageous embodiment along an angularly bent time delay path.
Mit der Schweißvorrichtung nach der Erfindung wird sowohl erreicht, daß die Augen des Schweißers während des Schweißvorganges sicher gegen Blitzstrahlen geschützt sind als auch daß bei Bearbeitung der Schweißnaht des Werkstücks bei vollem Erhalt der Sicht keine wegspringenden Materialtei lchen in die Augen bzw. in das Gesicht gelangen können. Auch ist es möglich, die Schweißzange einschließlich der Schaltvorrichtung beim Arbeiten in einer Hand zu halten und zu bedienen, während die andere Hand für andere Tätigkeiten frei ist.With the welding device according to the invention it is achieved both that the eyes of the welder are safely protected against lightning during the welding process and that when machining the weld seam of the workpiece with full preservation of the view no leaking material particles get into the eyes or face can. It is also possible to hold and operate the welding gun including the switching device while working in one hand while the other hand is free for other activities.

Fig. 8 die Schaltvorrichtung nach den Fig. 6 und 7 in vergrößerter Ausführungsform.Fig. 8, the switching device according to FIGS. 6 and 7 in an enlarged embodiment.
Die Schutzhaube nach den Fig. 1 und 3 besteht aus einem Schirm 1, der am Kopf des Schweißers befestigbar ist. In dem Schirm 1 befindet sich ein Sichtfenster 2, das bei aufgesetzter Schutzhaube einen freien Durchblick erlaubt. Parallel zu dem Sichtfenster 2 ist an der Innenseite der Schutzhaube ein Dunkelsichtglas 3 angeordnet, das in seitlichen Führungsprof len 4 verschiebbar geführt ist. Das Dunkelsi chtglas 3 ist mit einer seitlichen Führungsstange 5 verbunden. Die Führungsstange 5 ist an ihrem unteren Ende mit einem Steuerhebel 6 verbunden, der mit dem unteren Ende einer Rückholfeder 7 in Verbindung steht.1 and 3 consists of a screen 1 which can be attached to the head of the welder. In the screen 1 there is a viewing window 2 which allows a clear view when the protective hood is in place. Parallel to the viewing window 2, a dark viewing glass 3 is arranged on the inside of the protective hood, which is slidably guided in lateral guide profiles 4. The Dunkelsi chtglas 3 is connected to a side guide rod 5. The guide rod 5 is connected at its lower end to a control lever 6 which is connected to the lower end of a return spring 7.
Der Steuerhebel 6, an dessen einem Ende die Führungsstange 5 und die Rückholfeder 7 angreifen, ist an seinem anderen Ende bei der Ausführungsform nach den Fig. 1 und 3 mit einem Zugmagnet 8 wirksam verbunden. Der Zugmagnet 8 ist über ein Kabel 9 mit der Schweißzange nach Fig. 2 und Fig. 4 verbunden. Die Schweißzange 10, die von Hand zu halten ist und die mit einem Schweißt ansformator 11 als Stromquelle im Verbindung steht, hat eine Schaltvorrichtung 12. Die Scha Itvorri chtung 12 weist zwei im Abstand angeordnete Kontakte 13 und 14 auf, die unabhängig voneinander durch ein gemeinsames, verschiebbares Betätigungsorgan 15 ein- und ausschaltbar sind. Dabei sind die Kontakte 13 und 14 derart angeordnet, daß durch Verschieben des Betätigungsorgans 15 immer nur ein Kontakt geschaltet ist. Der Kontakt 13 dient zur Betätigung des Zugmagneten 8, während der Kontakt 14 das Ein- und Ausschalten der Schweißzange bewirkt.The control lever 6, at one end of which the guide rod 5 and the return spring 7 engage, is effectively connected at its other end in the embodiment according to FIGS. 1 and 3 with a pull magnet 8. The pull magnet 8 is connected via a cable 9 to the welding gun according to FIGS. 2 and 4. The welding gun 10, which is to be held by hand and which is connected to a welding transformer 11 as a power source, has one Switching device 12. The switching device 12 has two spaced contacts 13 and 14 which can be switched on and off independently of one another by a common, displaceable actuating member 15. The contacts 13 and 14 are arranged such that only one contact is switched by moving the actuator 15. The contact 13 serves to actuate the pull magnet 8, while the contact 14 causes the welding gun to be switched on and off.
Ist der Kontakt 13 betätigt, zieht der Zugmagnet 8 gegen die Kraft der Rückholfeder 7 das Dunke lsi chtg las 3 nach unten, so daß der Schweißer ungehindert aus der Schutzhaube sehen kann. Bei dieser Stellung des Schaltorgan 15, wie sie in Fig. 4 gezeigt ist, bleibt die Schweißzange 10 ausgescha Itet .If the contact 13 is actuated, the pull magnet 8 pulls the darkness lsi chtg las 3 downward against the force of the return spring 7, so that the welder can see freely from the protective hood. In this position of the switching element 15, as shown in Fig. 4, the welding gun 10 remains switched off.
Wird das Schaltorgan 15 nach oben geschoben, so daß der Kontakt 14 betätigt und die Schweißzange angeschaltet wird, verläßt das Schaltorgan 15 den Kontakt 13, wodurch der Zugmagnet 8 abgeschaltet wird, was zur Folge hat, daß die Rückholfeder 7 das Dunkelsichtglas 3 vor das Sichtfenster 2 schiebt und damit für den Schweißer einen Augenschutz gewährleistet.If the switching element 15 is pushed upwards so that the contact 14 is actuated and the welding gun is switched on, the switching element 15 leaves the contact 13, whereby the pull magnet 8 is switched off, with the result that the return spring 7 places the dark glass 3 in front of the viewing window 2 pushes and thus guarantees eye protection for the welder.
Wie in Fig. 5 gezeigt ist, ist eine Zeitverzögerungsbahn 16 für das Schaltorgan 15 vorgesehen, die winklig abgeknickt ist und sicherstellt, daß auch bei schnellem Verschieben des Schaltorgans 15 die Schweißzange 10 nicht eher eingeschaltet wird, als die Rückholfeder 7 das Dunkelsichtglas 3 in die gewünschte Position gebracht hat. Bei der Ausführungsform nach den Fig. 6 bis 8 ist an Stelle des Zugmagneten 8 nach Fig. 1 zwischen dem Steuerhebel 6 und der Schaltvorrichtung 12 ein Bowdenzug 8a vorgesehen, der wiederum mittels des Schaltorgangs 15 einschaltbar ist, um das Dunkelsichtglas 3 entgegen der Kraft der Rückholfeder 7 in eine die Sicht freigebende Stellung zu bringen. Auch hierbei ist gesichert, daß der Kontakt zur Schweißzange 10 erst dann geschlossen wird, wenn das Dunkelsichtglas 3 durch die Rückholfeder 7 in Augenschutzstellung zurückgebracht ist.As shown in Fig. 5, a time delay path 16 is provided for the switching element 15, which is kinked at an angle and ensures that, even when the switching element 15 is moved quickly, the welding gun 10 is not switched on earlier than the return spring 7, the dark glass 3 in the brought the desired position. In the embodiment according to FIGS. 6 to 8, a Bowden cable 8a is provided instead of the pull magnet 8 according to FIG. 1 between the control lever 6 and the switching device 12, which in turn can be switched on by means of the switching mechanism 15 in order to counter the force of the dark glass 3 Bring return spring 7 in a position releasing the view. Here, too, it is ensured that the contact to the welding gun 10 is only closed when the dark glass 3 is returned to the eye protection position by the return spring 7.
Wie Fig. 8 zeigt, ist auch hierbei sichergestellt, daß durch eine Zeitverzögerungsbahn 16a für das Schaltorgang 15 ein Einschalten der Schweißzange erst dann erfolgt, wenn der Augenschutz wirksam ist. As shown in FIG. 8, this also ensures that the welding gun is only switched on by a time delay path 16a for the switching operation 15 when the eye protection is effective.
