beinen von Kraftfahrzeugen.legs of motor vehicles.
Zum Ausbauen der Vorderfedern oder der Federn der Federbeine eines Kraftfahrzeuges warden Üblicherweise Federspanner eingesetzt. Das Arbeiten mit Federspannern ist jedoch gefährlich» da die KrsEL der eingespannten Federn erheblich ist. Insbesondere Ibei auszubauenden gebrochenen Federn ist der Einsatz &bgr; lines, Federspanners problematisch. Spring compressors are usually used to remove the front springs or the springs of the suspension struts of a motor vehicle. However, working with spring compressors is dangerous because the compression of the clamped springs is significant. The use of spring compressors is particularly problematic when removing broken springs.

Der Brflndung liegt die Aufgabe zugrunde» eine Vorrichtung turn Ausglühen auszubauender Spiralfedern zu schaffen» durch die es möglich wird» Spiralfedern eines Kraftfahrzeugs problemlos auszubauen.The aim of the invention is to create a device for annealing spiral springs that are to be removed, which will make it possible to remove spiral springs from a motor vehicle without any problems.
Brfindungsgemaß wird diese Aufgabe gelöst durch eine erste, im oberen Bereich der auszuglühenden Feder auf diese aufzusetzende Kontaktklemme» eine zweite» im unteren Bereich der auszuglühenden Peder auf diese aufzusetzende Kontaktklemme und die Kontaktklemmen mit einem Schweißtrane formator oder dgl. verbindende Stromkabel.According to the invention, this object is achieved by a first contact clamp to be placed on the spring to be annealed in the upper region of the spring, a second contact clamp to be placed on the spring to be annealed in the lower region of the spring, and power cables connecting the contact clamps to a welding transformer or the like.
Bin bevorzugtes AusfUhrungsbeiepit'l zeichnet sich dadurch aus» daß die Klemme mit auswechselbaren Brsatzsttlcken versehen sind.A preferred embodiment is characterized by the fact that the clamp is provided with exchangeable brackets.
Die Erfindung wird im folgenden anhand einer Zeichnung erläutert. Dabei zeigt:The invention is explained below with reference to a drawing.

Die Vorrichtung besteht aus zwei Kontaktklemmen 2, 3, die über Stromkabel 8 mit einem Schweißtransformator oder dgl. verbunden ist. Die Vorrichtung ermöglicht es, die auszubauende Spiralfeder auszuglühen und ihr damit die Federkraft zu nehmen. Dies wird dadurch bewirkt, daß die Vorrichtung mit der oberen Kontaktklemae 2 in oberen Bereich der auszubauenden Feder 1 angeklemmt wird, wahrend die untere Kontaktklemme 3 entsprechend im unterenThe device consists of two contact clamps 2, 3, which are connected to a welding transformer or the like via a power cable 8. The device makes it possible to anneal the spiral spring to be removed and thus remove its spring force. This is achieved by clamping the device with the upper contact clamp 2 in the upper area of the spring 1 to be removed, while the lower contact clamp 3 is correspondingly in the lower

Bereich der auszubauenden Feder 1 angeklemmt wird. Nach Aufgeben einer Spannung auf die Stromkabel 8 fließt ein erheblicher Strom durch die auszubauende Feder 1. Aufgrund des Ohm&bgr;ehe&eegr; Widerstandes entwickelt sich eine erhebliche WMrme in der Feder 1« die zu einem Ausglühen und damit zu einem Verlust der Federkraft führt. Die ausgeglühte Feder kann sodann problemlos - beispielsweise unter Einsatz der Üblichen Federspanner - ausgebaut werden.The spring 1 is clamped to the area of the spring to be removed. After applying a voltage to the power cable 8, a considerable current flows through the spring 1 to be removed. Due to the ohmic resistance, a considerable heat develops in the spring 1, which leads to annealing and thus to a loss of spring force. The annealed spring can then be removed without any problem - for example using the usual spring compressor.
Fig. 2 verdeutlicht eine bevorzugte Ausbildung der Vorrichtung. Diese ist mit einem Hebel 7 versehen, die Über den ein Stift gegen die Kraft einer Feder 9 herabgezogen und die Öffnung zur Gegenseite der Klemme 1 freigibt. Jetzt kann die Klemme auf die Windung der auszubauenden Spiralfeder aufgesetzt werden. Nach Hochschieben des Regelungestifts sitzt die Klemme fest auf. Die Zeichnung verdeutlicht weiter, daß an den Innenseiten der Klemmen 2, 3 auswechselbare Einsatzstlicke eingesetzt sein können. Diese schützen die eigentlichen Kontaktklemmen vor einer unmittelbaren Berührung mit der auszubauenden Feder und verhindern somit ein Verschweißen der Kontaktklemme selbst mit der Feder.Fig. 2 shows a preferred design of the device. This is provided with a lever 7, over which a pin is pulled down against the force of a spring 9 and opens the opening on the opposite side of the terminal 1. Now the terminal can be placed on the winding of the spiral spring to be removed. After pushing up the control pin, the terminal sits firmly in place. The drawing also shows that replaceable inserts can be inserted on the inside of the terminals 2, 3. These protect the actual contact terminals from direct contact with the spring to be removed and thus prevent the contact terminal itself from welding to the spring.
Fig. 2 verdeutlicht weiter, daß der Handgriff 6 der Vorrichtung mit einer Schiebeeinrichtung 5 versehen ist. Der Handgriff besteht dabei aus einem hitzebeständigen Material.Fig. 2 further shows that the handle 6 of the device is provided with a sliding device 5. The handle is made of a heat-resistant material.
