Abstract

A high-strength , cold-hardening two-component adhesive is used for sticking an outer panel especially onto an inner panel or reinforcement panel. A defined pressure is applied and held onto the dimensionally more stable panel to which a less dimensionally stable panel is stuck.

Description

Die Erfindung bezieht sich auf ein Verfahren der im Oberbegriff des ersten Anspruchs angegebenen Art. The invention relates to a method in the preamble of the first Art.

Es ist allgemein im Karosseriebau von Kraftfahrzeugen bekannt, ein Außenblech mit einem Innenblech oder ein Außenblech mit einem Verstärkungsblech zu verkleben, damit eine ausreichende Bausteifigkeit erzielt wird und Schwingungen und Flattern des Außenbleches vermieden werden. Üblicherweise verwendet man einen warm aushärtenden Klebstoff. It is generally known in the body construction of motor vehicles to have an outer panel to glue an inner sheet or an outer sheet with a reinforcing sheet, so that sufficient rigidity is achieved and vibrations and flutter of the outer sheet can be avoided. Usually you use a warm one curing adhesive.

Warm aushärtende Klebstoffe mit einem hohen Schubmodul konnten sich nicht durchsetzen, da dies zu Verwerfungen oder Eindellungen auf dem Außenblech führte. Der Grund hierfür liegt darin, dass beim Abkühlen nach einem Ofenprozess zum Aushärten des Klebstoffes das Außenblech schneller abkühlte als das Innenblech. Damit entstanden Spannungen im Außenblechbereich zwischen den einzelnen Klebstoffstellen. Thermosetting adhesives with a high shear modulus could not enforce, as this leads to warping or indentations on the outer sheet led. The reason for this is that when cooling after an oven process the outer sheet cooled faster than that to harden the adhesive Inner panel. This created tension in the outer sheet metal area between the individual glue spots.

Um dies zu verhindern, ist man dazu übergegangen, warm aushärtende Klebstoffe zu verwenden, die weich elastisch sind, d. h. deren Schubmodul mit seinem Maximalwert auf einem sehr niedrigen Niveau, beispielsweise bei 6 Mpa, liegt. Damit konnten der Aufbau von Spannungen beim Abkühlen im Außenblech verhindert werden. Allerdings ist aufgrund der hohen Elastizität der Klebstoffe eine Erhöhung der Bauteilsteifigkeit nicht möglich. Weiterhin ist durch den herstellungsbedingten großen und schwer reproduzierbaren Klebspalt die Verbindung weich und der Klebstoffverbrauch hoch. To prevent this from happening, people have started to use thermosetting adhesives to use that are softly elastic, d. H. whose thrust module with his The maximum value is at a very low level, for example 6 MPa. In order to could prevent the build-up of tension when cooling in the outer sheet become. However, due to the high elasticity of the adhesives, there is an increase component rigidity is not possible. Furthermore, due to the manufacturing large and difficult to reproduce adhesive gap the connection soft and the High adhesive consumption.

Aufgabe der vorliegenden Erfindung ist es, hier Abhilfe zu schaffen. The object of the present invention is to remedy this.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des ersten Anspruchs gelöst. This object is achieved by the features of the first claim solved.

Die Lösung basiert auf der Erkenntnis, dass durch die Verwendung von hochfesten Klebstoffen, deren Schubmodul deutlich über 6 Mpa liegt und bevorzugt > 250 Mpa, besonders bevorzugt > 300 Mpa, ist, und die kalt aushärtend sind, der Warmaushärtungsprozess gespart werden kann und damit auch die aufgrund der unterschiedlichen Abkühlbedingungen auftretenden Verwerfungen oder Eindellungen vermieden werden. Damit werden auch sehr steife Bauteile erreicht, ohne dass deren Oberflächenqualität beeinflusst wird. The solution is based on the knowledge that by using high-strength Adhesives whose shear modulus is significantly above 6 Mpa and preferably> 250 Mpa, is particularly preferred> 300 Mpa, and which are cold-curing, the Heat curing process can be saved and therefore also due to the warps or indentations occurring under different cooling conditions be avoided. This means that even very stiff components can be achieved without whose surface quality is influenced.

Bisher hat man im Automobilbau vermieden, kalt aushärtende Klebstoffe zu verwenden, da im Produktionsprozess der Karosserie entweder schon im Rohbau oder spätestens in der Lackhärtung ein Ofenprozess vorgesehen war, der dann auch zum Aushärten des Klebstoffs herangezogen werden konnte. So far, cold-curing adhesives have been avoided in automotive engineering use, because in the production process of the body either already in the shell or at the latest in the curing of the paint, an oven process was provided, which then too could be used to cure the adhesive.

Die Weiterbildung nach Anspruch 2 hat den Vorteil, dass das maßungenauere Blech unter Spannung, also maßgenau gedrückt, auf das maßgenauere Blech während der Kaltaushärtung des Klebstoffes aufgedrückt wird. Damit entsteht ein formgenaues Bauteil, auch wenn einer der beteiligten Komponenten nicht so formgenau hergestellt wurde. The development according to claim 2 has the advantage that the sheet is less accurate under tension, i.e. pressed to size, onto the more accurate sheet during the cold curing of the adhesive is pressed on. This creates a Form-fitting component, even if one of the components involved is not so form-fitting was produced.

Letzteres hat im Automobilbau den Vorteil, dass die meist komplizierteren Innenbleche oder Verstärkungsbleche, die nur mit einem überproportional hohen Aufwand maßgenau gepresst werden können, nunmehr mit einer leichten Ungenauigkeit hergestellt werden können, da sie auf das in der Regel einfacher maßgenau herzustellende Außenblech aufgedrückt werden können. Der Druck, der während des Kaltaushärtens aufgebracht wird, wird so gewählt, dass sich das Innenblech so verformt, dass es konturgenau mit dem Außenblech verbunden werden kann. Hierzu wird beispielsweise das Außenblech zuerst in eine maßgenaue Form gelegt und dann das Innenblech, nachdem der Klebstoff aufgebracht wurde, durch Spanneinrichtungen verspannt auf das Außenblech aufgelegt wird und solange gehalten wird, bis die Kaltaushärtung des Klebstoffes erfolgt ist. Damit lassen sich auch eine Minimierung des Klebstoffspaltes erzielen, was einen geringeren Klebstoffverbrauch und damit Kosteneinsparungen bewirkt. The latter has the advantage in automobile construction that the mostly more complicated ones Inner sheets or reinforcing sheets that only require a disproportionately high effort can be pressed to size, now with a slight inaccuracy can be produced, since they are usually easier to measure outer sheet to be manufactured can be pressed on. The pressure that occurs during the Cold curing is applied so that the inner sheet is so deformed so that it can be connected to the outer panel with precise contours. For this purpose, for example, the outer sheet is first placed in a dimensionally accurate shape and then through the inner panel after the adhesive is applied Clamping devices are clamped on the outer sheet and held for as long until the adhesive has cold hardened. This can also be used Achieve minimization of the adhesive gap, which means less adhesive consumption and thus brings about cost savings.

Ein weiterer Vorteil des erfindungsgemäßen Verfahrens ist darin zu sehen, dass die im Rohbau eingesetzten Öfen zur Aushärtung entfallen können und keine Zusatzmaßnahmen ergriffen werden müssen, um geklebte Bauteile im Lacktrocknungsofen zu fixieren. Another advantage of the method according to the invention is that the ovens used in the body shop can be omitted for curing and none Additional measures must be taken to glue components in the paint drying oven to fix.
