Description
Handgerät für elektrische Widerstandspunkt- oder Nahtschweißung mit zwei an einem Handgriff nebeneinander angebrachten Elektroden Gegenstand der Erfindung ist ein Handgerät für elektrische Widerstandspunkt- oder Nahtschweißung mit zwei 'an einem Handgriff nebeneinander angebrachten Elektroden.Hand tool for electrical resistance spot or seam welding with two electrodes attached to one another on a handle are the subject of the invention is a hand-held device for electrical resistance spot or seam welding with two '' electrodes attached next to each other on a handle.
Es ist bereits bekannt, an einen Magnetbügel angeordnete Elektroden nachgiebig anzuordnen. Hierbei müssen .aber beide Elektroden elastisch gelagert sein:, damit sie sich der durch den Magnetbügel bestimmten Laue anpassen können. Dabei Wird aber die Stromzufuhr zu den Elektroden nicht durch die Elektroden gesteuert, sondern durch besondere innefhalb der Maschine .angeordnete Schalter.It is already known to have electrodes arranged on a magnetic bracket to be arranged yielding. Here, however, both electrodes must be elastically supported be: so that you can adapt to the temperament determined by the magnetic bracket. However, the current supply to the electrodes is not controlled by the electrodes, but by special switches arranged inside the machine.
Bei einem. Handgerät läßt sich eine solche Anordnung nicht anwenden. Bei diesem können die Elektroden niemals so gleichmäßig gegen die zu schweißenden Gegenstände geführt werden; ditß leine gleichmäßige Berührung derselben durch die Elektroden mit Sicherheit erreicht werden kann.At a. Such an arrangement cannot be used with a hand-held device. With this the electrodes can never be so evenly against the one to be welded Objects are led; ditß not evenly touch them by the Electrodes can be reached with certainty.
Um nun diese Mängel zu beseitigen, wird gemäß der Erfindung die eine Elektrode fest und die andere elastisch nachgiebig angeordnet, und die elastisch nachgiebige Elektrode schaltet beim Ausweichen den Schweißstrom ein.In order to eliminate these shortcomings, one is according to the invention Electrode fixed and the other arranged elastically resilient, and the elastic The flexible electrode switches on the welding current when swerving.
Diese Anordnung hat den Vorteil, daß beim Andrücken des Handgerätes die feste Elektrode dem Gerät eine gute Führung gibt, während die elastisch nachgiebige Elektrode nach ihrem Aufsetzen so weit niedergedrückt werden ruß, bis der Schweißstrom eingeschaltet ist. -Besonders vorteilhaft ist diese Anordnung, wenn man sie zum Schweißen von Ecknähten benutzen will. In diesem Falle können Rollenelektroden vorgesehen werden, die im Winkel der Ecknaht zueinander eingestellt werden können.This arrangement has the advantage that when you press the hand-held device the fixed electrode gives the device good guidance, while the elastically yielding one Electrode must be pressed down so far after it has been placed on soot until the welding current is switched on. - This arrangement is particularly advantageous if you use it for Welding corner seams want to use. In this case roller electrodes are provided, which can be adjusted to each other at the angle of the corner seam.
Diese Anordnung bietet die Möglichkeit, bei festliegendem Abstand
der festen und nachgiebigen Elektrode den Abstand der
Die Zeichnung veranschaulicht das neue Gerät, und zwar zeigen Abb. i und 2 eine teilweise geschnittene Seitenansicht und Oberansicht, Abb.3 Endansicht eines ähnlichen Gerätes mit einstellbaren und auswechselbarem. Elektroden, an denen auch Rollenelektroden verstellbar befestigt werden können.The drawing illustrates the new device, namely Fig. i and 2 a partially sectioned side view and top view, Figure 3 end view of a similar device with adjustable and interchangeable. Electrodes on which roller electrodes can also be attached in an adjustable manner.
Nach Abb. i und 2 trägt ein, Handgriff i in zwei Isolierstücken 2 eingesetzt Führungskörper 3 von Widerstandspunkts:chweißelektroden 4, 5, und zwar ist die eine Elektrode 4 in festem Sitz :eingepreßt, während die andere Elektrode 5 gegen den Druck einer Feder 6 längs nachgiebig eingesetzt ist, um auch bei schiefem Aufsetzen des Gerätes immer Andruck beider Elektroden zu ermöglichen. An die beiden Führungskörper 3 sind starke Stromzuleitungskabel7 für den Schweißstrom angeklemmt oder angeschraubt. Ein im Griff i angebrachter Schalthebel 8 steuert einen Relaisstromkreis 9, der beim Drücken des Schalthebels 8 den Schweißstrom einschaltet.According to Fig. I and 2, a handle i in two insulating pieces 2 inserted guide body 3 of resistance point: welding electrodes 4, 5, namely one electrode 4 is firmly seated: pressed in, while the other electrode 5 against the pressure of a spring 6 is inserted longitudinally resilient to even with crooked Always allow both electrodes to be applied when the device is placed. To both of them Strong power supply cables7 for the welding current are attached to the guide body 3 or screwed on. A shift lever 8 mounted in the handle i controls a relay circuit 9, which switches on the welding current when the switching lever 8 is pressed.
Außerdem ist bei der längs nachgiebigen Elektrode 5 der Führungskörper 3 als Isolierkörper ausgebildet und nur in seinem nahe der Feder 6 liegenden Teil aus Metall hergestellt, an das das Schweißkabel ? angeschlossen ist. So ergibt sich bei Drucklosigket an den Elektroden zugleich auch S:tromlosigkeit des Gerätes und erst beim Andrücken. der Elektroden die Verbindung der nachgiebigen Elektrode 5 mit ihrem Stromanschluß 7. Der Schalter 8 nebst seiner Relaisleitung 9 kann fehlen. Der Schweißtransformatar bleibt dann dauernd unter Strom, und nur sein Sekundärkreis wird durch die Elektrode 5 geschaltet. Wo Lichtbogenbildung zu befürchten ist, kann statt dessen der Primärstrom durch den Elektrodenandruck gesteuert werden.In addition, the guide body is in the case of the longitudinally flexible electrode 5 3 designed as an insulating body and only in its part located near the spring 6 made of metal to which the welding cable? connected. So it turns out when there is no pressure on the electrodes, there is also S: de-energization of the device and only when pressing. of the electrodes the connection of the flexible electrode 5 with their power connection 7. The switch 8 and its relay line 9 may be missing. The welding transformer is then permanently energized, and only its secondary circuit is switched by the electrode 5. Where arcing is to be feared, can instead, the primary current can be controlled by the electrode pressure.
Nach Abb.3 sind bei einem grundsätzlich ähnlichen Gerät, bei dem nur
am Griff i die
