Description

Verfahren zum Verbinden zweier MetallplattenMethod for joining two metal plates

Die Erfindung betrifft ein Verfahren zum Verbinden zweier Metallplatten, wobei in einer Metallplatte eine Deformation bzw. ein Buckel erzeugt, diese Metallplatte mit dem Buckel der anderen Metallplatte angelegt und der Buckel in die andere Metallplatte eingepresst und im Buckelbereich verschweisst wird.The invention relates to a method for connecting two metal plates, whereby a deformation or a hump is generated in a metal plate, this metal plate with the hump of the other metal plate and the hump into the other metal plate is pressed in and welded in the hump area.

Allgemein bekannt ist das sogenannte Widerstands-Punktschweissverfahren. Im Gegensatz dazu wird bei dem sogenannten Kondensator-Impulsschweissen eine Energiemenge, die zum Verschmelzen des Gefüges einer Schweissstelle notwendig ist, in einem elektrischen Kondensator bei hoher Spannung gespeichert. Zum Schweissen selbst wird die Kapazität des Kondensators über eine Primärwicklung eines Impulstransformators entladen. Dieses spezielle Impulsschweissen wird beim einfachen Punktschweissen kaum angewandt, weil es wegen der Kürze der Schweisszeit nicht zu einer Durchwärmung der zu verschweissenden Teile kommen kann und die Elektroden häufig kleben. Hierzu wird das spezielle Buckelschweissen angewandt, bei dem der Schweissstrom zwischen Erhebungen oder Ausprägungen auf den zu verschweissenden Flächen fliesst, wodurch der Schweissquerschnitt auf diese Bereiche begrenzt wird. Auf diese Weise ermöglicht das Bukkelschweissen Schweissverbindungen, die mit anderen Schweissverfahren nicht hergestellt werden können. Die Gleichmässigkeit des Schmelzflusses wird verbessert, die Lebensdauer der Elektroden verlängert und eine Fertigungsbeschleunigung ermöglicht.The so-called resistance spot welding process is well known. In contrast to this, in the so-called capacitor pulse welding, an amount of energy is which is necessary to fuse the structure of a weld into an electrical one Capacitor stored at high voltage. The capacity becomes the welding itself of the capacitor is discharged through a primary winding of a pulse transformer. This special impulse welding is rarely used in simple spot welding because Due to the short welding time, there is no warming through of the parts to be welded Parts can come and the electrodes often stick. The special projection welding is used for this applied in which the welding current between elevations or expressions on the surfaces to be welded flows, causing the weld cross-section to affect these areas is limited. In this way, buccal welding enables welded connections, which cannot be produced with other welding processes. The evenness the melt flow is improved, the life of the electrodes is extended and enables production to be accelerated.

Das Widerstands-Punktschweissverfahren hat weiterhin speziell den Nachteil, bei Verbindung von Metallplatte und Metallverbundplatte, welche aus einer auf oder zwischen mehreren Metallplatten eingebrachten Kunststoffschicht besteht, dass es bei dem Schweissvorgang zu einem Aufschmelzen der Kunststoffschicht und zu Blasenbildung kommt. Zudem ist die Stromleitung infolge der isolierenden Wirkung der Kunststoffschicht nicht gewährleistet. Der Erfinder hat sich zum Ziel gesetzt, die bekannten Eigenschaften der Buckelschweissverbindung beim Zusammenfügen zweier Metallteile zu verbessern, insbesondere bei der Verbindung einer Metallplatte mit einer Metall-Kunststoffverbundplatte.The resistance spot welding process continues to have the special Disadvantage when connecting metal plate and metal composite plate, which consists of a consists of a plastic layer placed on or between several metal plates, that during the welding process the plastic layer melts and blistering occurs. In addition, the power line is due to the insulating effect the plastic layer is not guaranteed. The inventor has set himself the goal of the well-known properties of the projection welded joint when joining two To improve metal parts, especially when connecting a metal plate with a metal-plastic composite panel.

Zur Lösung dieser Aufgabe führt, dass die eine und/oder andere Metallplatte bzw. Schicht im Anlagebereich vor dem Einpressen des Buckels mit einer Klebstoffschicht versehen wird. Diese Klebstoffschicht besteht erfindungsgemäss aus einem Zweikomponentenkleber, beispielsweise aus einem PVC-Plastisol.One and / or the other metal plate leads to the solution of this problem or layer in the contact area before pressing in the boss with an adhesive layer is provided. According to the invention, this adhesive layer consists of a two-component adhesive, for example from a PVC plastisol.

Bei Versuchen hat sich erwiesen, dass durch ein derartiges Verfahren eine Verbindung erzeugt wird, welche bei Belastung eher zu einem Bruch der Verbundplatte als zu einem Lösen der Verbindung führt. Ueberraschend hat sich weiterhin herausgestellt, dass die Schweisstelle nicht etwa an der Spitze des Buckels auftritt, sondern den Buckel etwa ringförmig umgibt. Hierdurch wird eine wesentlich festere Verbindung erzeugt.Tests have shown that by using such a method a connection is created which, when loaded, tends to break the composite panel than leads to a loosening of the connection. Surprisingly it turned out that that the welding point does not appear at the tip of the hump, but rather the Surrounding hump approximately in a ring. This creates a much stronger connection generated.

Dieses Verfahren kann nicht nur angewandt werden, wenn eine einfache Metallplatte auf eine andere Metallplatte aufge- schweisst werden soll. Bevorzugt findet es Anwendung bei der Verbindung von einer einfachen Metallplatte mit einer Verbundplatte. Dabei kann die Verbundplatte lediglich aus einer Metallschicht bestehen, auf welche eine Kunststoffschicht aufgebracht ist. Gedacht ist aber insbesondere an die Verbindung von Metallplatte mit Verbundplatte, welche aus zwei Metallschichten mit dazwischen angeordneter Kunststoffschicht besteht.This procedure cannot only be applied when a simple one Metal plate attached to another metal plate be welded target. It is preferably used when connecting a simple metal plate with a composite panel. The composite panel can only consist of a metal layer exist, on which a plastic layer is applied. But it is especially thought to the connection of metal plate with composite plate, which consists of two metal layers with a plastic layer arranged in between.

Weitere Vorteile, Merkmale und Einzelheiten ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels sowie anhand der Zeichnung; diese zeigt in Fig. 1 eine schematische, teilweise geschnittene Darstellung einer Vorrichtung zum Verbinden zweier Platten; Fig. 2 einen vergrössert dargestellten Ausschnitt aus Fig. 1 in einer anderen Arbeitslage.Further advantages, features and details emerge from the following Description of a preferred embodiment and with reference to the drawing; this shows in Fig. 1 a schematic, partially sectioned representation of a Device for joining two panels; Fig. 2 shows an enlarged Section from Fig. 1 in a different working position.

Nach Fig. 1 sollen zwei Platten 1 und 2 miteinander verbunden werden. Die eine Platte 1 ist dabei eine einfache Metallplatte, die andere Platte 2 dagegen eine Verbundplatte, bei welcher eine Kunststoffschicht 3 von Metallschichten 4 und 5 beidseits bedeckt ist.According to Fig. 1, two plates 1 and 2 are to be connected to one another. One plate 1 is a simple metal plate, while the other plate 2 is a composite panel, in which a plastic layer 3 of metal layers 4 and 5 is covered on both sides.

Zum Verbinden werden beide Platten 1 und 2 auf eine Unterlage 6 gelegt, wobei sie sich in einem Bereich 1 überlappen. Innerhalb dieses Bereiches 1 wird zwischen beide Platten 1 und 2 ein Klebstoff 7 eingebracht, sowie an die Platten 1 und die Metallschicht 5 jeweils eine Elektrode 8, 9 herangeführt, welche über Leitungen 10 mit einer -- nicht dargestellten -- Schweissvorrichtung bzw. einem Transformator verbunden sind.To connect both panels 1 and 2 are placed on a base 6, where they overlap in a region 1. Within this area 1 is between both plates 1 and 2 an adhesive 7 introduced, as well as one electrode 8, 9 each brought up to the plates 1 and the metal layer 5, which via lines 10 with a - welding device - not shown or a transformer are connected.

Die eine Elektrode 8 ist absenkbar ausgebildet und greift mit einem querschnittlich hammerartig verbreiterten Kopf 11 die Platte 1 an. Dabei drückt sie einen vorher in der Platte 1 erzeugten Buckel in die Metallschicht 4 und die Kunststoffschicht 3 (Fig. 2).One electrode 8 is designed so that it can be lowered and engages with one cross-sectionally hammer-like widened head 11 the plate 1. It pushes they a previously generated in the plate 1 hump in the metal layer 4 and the Plastic layer 3 (Fig. 2).

Nach Anlegen einer Spannung an die Elektroden 8, 9 wird zwischen der Platte 1 und der Metallschicht 4 eine Schweissverbindung 14 hergestellt, welche überraschenderweise nicht am Tiefpunkt der Deformation 12 stattfindet, sondern ringförmig die Deformation 12 umgibt.After applying a voltage to the electrodes 8, 9 is between the Plate 1 and the metal layer 4 a welded connection 14 is made, which Surprisingly, it does not take place at the lowest point of the deformation 12, but in an annular manner the deformation 12 surrounds.

Da die Kunststoffschicht 3 als elektrischer Isolator wirkt, ist erfindungsgemäss vorgesehen, den Stromfluss von der Elektrode 8 über die Platte 1, die Metallschicht 4, eine Leiterzange 15 auf die Metallschicht 5 und von dort zur Elektrode 9 zu gewährleisten. Da die Schweissdauer in der Regel nur wenige Millisekunden (etwa 4 msek) beträgt, kann eine derartige Ueberbrückung nur bei sehr geringem Leitungsweg Anwendung finden. Ist der Leitungsweg grösser, dürfte das sog. Nebenschlussverfahren Anwendung finden, bei dem die Elektrode 9 nicht mit der Metallschicht 5 verbunden ist, sondern der Metallschicht 4 neben der Elektrode 8 aufsitzt.Since the plastic layer 3 acts as an electrical insulator, is according to the invention provided the current flow from the electrode 8 via the plate 1, the metal layer 4, a pair of conductor pliers 15 on the metal layer 5 and from there to the electrode 9. Since the welding time is usually only a few milliseconds (about 4 msec), Such a bridging can only be used with a very short line path. If the line path is longer, the so-called shunt procedure should be used, in which the electrode 9 is not connected to the metal layer 5, but rather the Metal layer 4 is seated next to the electrode 8.
