Abstract

A welding element is formed from a sleeve (10), which is cold-pressed from a thin metal sheet and the open end of which forms the welding face, which is optionally provided with a flange (11). A thread (13) may be rolled in on the outer face of the sleeve (10). In spite of the small amount of material used, this welding element is stable as a result of the forming process. On the other hand, because of the thinness of the wall of the welding element, the MARC welding method, which operates with a low energy input, is particularly suitable for welding-on operations.

Stand der Technik  State of the art
Aus EP 1 060 823 A1 sind aus Vollmaterial hergestellte Schweißelemente in Form von massiven Gewindebolzen oder auch Buchsen, Schweißmuttern oder 5 Gewindehülsen mit koaxialer Durchgangsbohrung bekannt, wobei die Stirnfläche auf eine zum Anschweißen mittels rotierendem Lichtbogen (MARC-Schweißen) geeignete Dicke verjüngt ist. Derartige Schweißelemente sind zwar robust aber im Materialeinsatz und in der Herstellung verhältnismäßig aufwändig.  EP 1 060 823 A1 discloses welding elements made of solid material in the form of solid threaded bolts or also bushes, weld nuts or 5 threaded sleeves with a coaxial through-hole, the end face being tapered to a thickness suitable for welding by means of a rotary arc (MARC welding). Although such welding elements are robust but relatively expensive in the use of materials and in the production.
In vielen Fällen, so insbesondere zum Fixieren von Kabelbindern an Fahr-0 zeugkarosserien, werden keine besonders widerstandsfähigen Schweißelemente benötigt. Vielmehr stehen dort Gesichtspunkte der Material- und Gewichtseinsparung im Vordergrund.  In many cases, in particular for fixing cable ties to vehicle bodies, no particularly resistant welding elements are required. Rather, there are aspects of material and weight savings in the foreground.
Abriss der Erfindung Outline of the invention
Dazu sieht die Erfindung das in Anspruch 1 angegebene, hülsenförmige5 Schweißelement vor, das durch Kaltpressen aus Blech hergestellt ist. Diese Pressverformung ist umso einfacher durchführbar, je dünner das Blechmaterial ist. Dennoch ergibt sich durch den Verformungsvorgang ein stabiles Schweißelement, dessen Rohrform auch dynamischen Belastungen, wie sie in Fahrzeugen auftreten, standzuhalten vermag. Die erwünschte Gewichtseinsparung wird dabei auto- 0 matisch erreicht.  For this purpose, the invention provides the sleeve-shaped 5 welding element specified in claim 1, which is produced by cold pressing from sheet metal. This compression deformation is easier to carry out the thinner the sheet material. Nevertheless, the deformation process results in a stable welding element whose tubular shape is also able to withstand dynamic loads, such as occur in vehicles. The desired weight saving is achieved automatically.
Wegen seiner hohlen Form vermag das erfindungsgemäße Schweißelement sogar höheren dynamischen Kräften zu widerstehen als herkömmliche Vollbolzen, weil solche Kräfte in erheblichem Maß durch Verformungen der Rohrform aufgenommen werden und nicht so leicht zu einem Abreißen führen. Because of its hollow shape, the welding element according to the invention is able to withstand even higher dynamic forces than conventional solid bolts, because such forces are absorbed to a considerable extent by deformations of the pipe shape and not easily lead to tearing.
5 Der Pressvorgang ergibt eine am einen Ende durch eine vorzugsweise runde Kuppe geschlossene Hülse, wobei das andere, offene Ende eine ringförmige Anschweißfläche bildet. Diese ist wegen ihrer geschlossenen Ringform und wegen der geringen Dicke des Blechmaterials für das MARC-Schweißen bestens geeignet.5 The pressing process results in a closed at one end by a preferably round dome sleeve, the other, open end forms an annular welding surface. This is best suited for MARC welding because of its closed ring shape and because of the small thickness of the sheet metal material.
0 Umgekehrt ist das MARC-Schweißen wegen seines geringen Energieeintrags gerade für dünnwandige Schweißelemente besonders gut geeignet. Conversely, because of its low energy input, MARC welding is particularly well suited for thin-walled welding elements.
In die Außenfläche der Hülse lässt sich ein Gewinde einrollen, so dass ein Gewinde-Schweißbolzen entsteht. Statt eines Gewindes können auch ringförmige Rillen zur Fixierung von aufzusteckenden Kunststoffhalterungen eingerollt werden. Dabei bildet die beim Pressvorgang entstehende verrundete Kuppe eine praktische Einführhilfe. A thread can be rolled into the outer surface of the sleeve so that a threaded welding bolt is produced. Instead of a thread and annular grooves for fixing aufzusteckenden plastic mounts can be rolled. The rounded dome created during the pressing process forms a practical insertion aid.
Zur Erhöhung der Festigkeit kann an das offene Ende der Hülse ein nach außen weisender Flansch angeformt sein.  To increase the strength can be integrally formed on the open end of the sleeve, an outwardly facing flange.
In einer weiteren Ausgestaltung kann im Zuge des Pressvorgangs in einigem Abstand von der Anschweißfläche ein Flansch angeformt werden, der einen nach außen weisenden Teil und einen auf diesen nach innen zurückgefalteten Teil aufweist. Ein derart gestaltetes Schweißelement eignet sich insbesondere als Massebolzen, wobei der Doppelflansch eine genau definierte Anschlag- und Kontaktfläche für einen Kabelschuh ohne Beeinträchtigung durch die unterhalb des Flansches liegende Schweißung bildet.  In a further embodiment, in the course of the pressing process, at some distance from the weld-on surface, a flange can be molded, which has an outwardly facing part and a part folded back inward towards it. Such a designed welding element is particularly suitable as a ground bolt, the double flange forms a well-defined stop and contact surface for a cable lug without interference from lying below the flange weld.

Beschreibung von Ausführungsbeispielen Description of exemplary embodiments
Die Hülse 10 nach Fig. 1 ist in dem gezeigten Beispiel aus Stahlblech mit einer Dicke von weniger als 1 mm, vorzugsweise 0,8 mm, durch Kaltpressen so verformt worden, dass sie einen Außendurchmesser von 5 mm und eine axiale Länge von 14 mm aufweist. Am offenen Ende hat sie einen nach außen gerichteten Flansch 11 mit einem Außendurchmesser von 7 mm, am geschlossenen Ende eine etwa kugelkalottenförmige Kuppe 12. In die so gebildete Hülse ist gemäß Fig. 2 eine metrisches Außengewinde 13 (in dem gezeigten Beispiel eine M5- Gewinde) eingerollt. Beim Rollen wird der Durchmesser der Hülse mit Ausnahme der Gewindestege nach innen gedrängt. Anstelle des Gewindes 13 können auch mehrere ringförmige Rillen eingerollt werden. The sleeve 10 of Fig. 1 has been deformed by cold pressing in the example shown from steel sheet having a thickness of less than 1 mm, preferably 0.8 mm so that it has an outer diameter of 5 mm and an axial length of 14 mm , At the open end, it has an outwardly directed flange 11 with an outer diameter of 7 mm, at the closed end an approximately kugelkalottenförmige dome 12. In the thus formed sleeve is shown in FIG. 2, a metric external thread 13 (in the example shown, an M5 thread rolled up). When rolling, the diameter of the sleeve is different the thread ridges pushed inwards. Instead of the thread 13, a plurality of annular grooves can be rolled.
. Das so gestaltete Bauelement lässt sich als Schweißelement mit seinem Flansch 11, dessen Unterseite die Anschweißfläche 19 bildet, nach dem MARC- Verfahren, d.h. mit magnetisch bewegtem, längs des Flansches 11 umlaufendem Lichtbogen, auf ein (nicht dargestelltes) Trägerblech aufschweißen.  , The component designed in this way can be designed as a welding element with its flange 11, the underside of which forms the weld-on surface 19, according to the MARC method, i. with magnetically moved, along the flange 11 circulating arc, on a (not shown) to weld carrier plate.
Die oben angegebene Materialstärke von unter 1 mm ist für die Erfindung nicht wesentlich. Je nach Anwendungsfall kommen auch größere Dicken in Betracht.  The material thickness of less than 1 mm indicated above is not essential to the invention. Depending on the application, larger thicknesses come into consideration.
Das Schweißelement 20 nach Fig. 3 ist ähnlich gestaltet und hergestellt wie das nach Fig. 2 und ebenfalls mit einem metrischen Gewinde 13 versehen, wobei jedoch das geschlossene Ende 22 nicht kuppenartig verrundet, sondern abgeplattet ist.  The welding element 20 of FIG. 3 is similarly designed and manufactured as that of FIG. 2 and also provided with a metric thread 13, but the closed end 22 is not rounded like a circle, but is flattened.
Das Schweißelement nach Fig. 4 unterscheidet sich von dem nach Fig. 3 dadurch, dass es nicht mit einem metrischen sondern einem Grobgewinde 23 oder mit einer Reihe von ringförmigen Rillen (oder Rippen) versehen ist. Ferner weist der Flansch 31 eine sich nach unten verjüngende Ringkante 34 auf, die die Anschweißfläche definiert und die je nach den übrigen Abmessungen für den MARC-Schweißvorgang günstig sein kann.  The welding element of Fig. 4 differs from that of Fig. 3 in that it is not provided with a metric but a coarse thread 23 or with a series of annular grooves (or ribs). Furthermore, the flange 31 has a downwardly tapered annular edge 34 which defines the welding surface and which may be favorable for the MARC welding operation depending on the other dimensions.
Der in Fig. 5 gezeigte Schweißbolzen 40 hat wie der Schweißbolzen 30 nach Fig. 3 ein metrisches Außengewinde 13 und ist in Abstand von seiner Anschweißfläche 49 mit einem Großflansch 41 versehen, der einen nach außen gerichteten unteren Teil 35 und einen auf diesen zurückgefalteten unteren Teil 46 umfasst.  The welding stud 40 shown in FIG. 5, like the welding stud 30 of FIG. 3, has a metric male thread 13 and is spaced from its welding face 49 with a large flange 41 having an outwardly directed lower portion 35 and a lower portion folded back thereon 46 includes.
Dieser Bolzen 40 ist insbesondere als Massebolzen geeignet, wobei der obere Teil 45 des Flansches 41 eine definierte ebene Anschlag- und Kontaktfläche für einen aufzuschraubenden Kabelschuh bildet. Da die Anschweißfläche 49 unterhalb des unteren Teils 46 des Flansches 41 liegt, wird diese Kontaktfläche durch den Schweißvorgang nicht beeinträchtigt.  This bolt 40 is particularly suitable as a ground bolt, wherein the upper part 45 of the flange 41 forms a defined flat stop and contact surface for a cable lug to be screwed. Since the welding surface 49 is located below the lower part 46 of the flange 41, this contact surface is not affected by the welding operation.
Ferner läßt sich der Kabelschuh beim Aufschrauben auf das Gewinde 13 an dem Flansch 41 festziehen, ohne dass auf das Grundblech, an dem der Massebolzen 40 angeschweißt ist, nennenswerte Kräfte angreifen.  Furthermore, the cable lug when tightening on the thread 13 can be tightened to the flange 41, without significant forces attack on the base plate to which the ground pin 40 is welded.
Gemäß einem weiteren (nicht dargestellten) Ausführungsbeispiel kann bei einem Schweißelement, das vom geschlossenen Ende ausgehend ein Außenge- winde trägt, nahe dem offenen Ende einen Mehrkantbereich, insbesondere einen Sechskantbereich, vorgesehen sein, an dem ein solcher Gewindebolzen beim Anschrauben eines weiteren Bauteils festgehalten werden kann, um die Einleitung von Kräften in das Grundblech zu vermeiden. According to another exemplary embodiment (not shown), a polygonal area, in particular a hexagonal area, can be provided near the open end in the case of a welding element which bears an external thread starting from the closed end, to which a threaded bolt of this kind Screwing another component can be held in order to avoid the introduction of forces in the base plate.
In den oben beschriebenen Schweißelementen ist angenommen, dass das von der Anschweißfläche abgewandte Ende der kaltgepressten Hülse in seiner geschlossenen kuppenartigen oder auch abgeplatteten Form erhalten wird. Unter die Erfindung fallen aber auch Ausführungsformen, bei denen dieses Ende geöffnet ist, so dass sich Schweißelemente mit einer durchgehenden Bohrung ergeben, die gegebenenfalls mit einem Innengewinde versehen sein kann.  In the welding elements described above, it is assumed that the end of the cold-pressed sleeve facing away from the welding surface is obtained in its closed dome-shaped or even flattened form. However, the invention also covers embodiments in which this end is open, so that welding elements result in a through bore, which may optionally be provided with an internal thread.
