Description
Die Erfindung betrifft Bauteilabschnitte an galvanisierten Kunststoffbauteilen, welche zum dauerhaften Zusammenfügen mittels Ultraschallschweißprozess an einem weiteren Bauteil mit entsprechenden, aufnehmenden Durchbrüchen und Öffnungen Verwendung finden. The invention relates to component sections of galvanized plastic components, which are used for permanent assembly by means of ultrasonic welding process on another component with corresponding, receiving openings and openings.
Hybride Komponenten, also Komponenten, die aus mehr als einem Werkstoff hergestellt sind, gewinnen immer mehr an Bedeutung, insbesondere in der Automobilindustrie. Hier werden oft verschiedene und unterschiedlich geformte Dekorelemente zur dekorativen Aufwertung eingesetzt. Dazu verwendet man bekannte Technologien der Oberflächengestaltung wie Lackieren, Folienhinterspritzen, PVD- oder CVD-Beschichtungen oder Kombinationen der genannten Techniken. Unter PVD-Verfahren (englisch physical vapour deposition) versteht man ein Beschichtungsverfahren mittels physikalischer Gasphasenabscheidung. Es handelt es sich um eine Gruppe von vakuumbasierten Beschichtungsverfahren bzw. Dünnschichttechnologien, bei denen die Schicht direkt durch Kondensation eines Materialdampfes des Ausgangsmaterials gebildet wird. Unter CVD-Verfahren (englisch chemical vapor deposition) versteht man ein Beschichtungsverfahren mittels chemischer Gasphasenabscheidung. Dabei wird an der erhitzten Oberfläche eines Substrates aufgrund einer chemischen Reaktion aus der Gasphase eine Feststoffkomponente abgeschieden. Mit den genannten Verfahren können galvanisierte und metallische Oberflächen bereitgestellt werden. Hybrid components, ie components made from more than one material, are becoming increasingly important, especially in the automotive industry. Here, different and differently shaped decorative elements are often used for decorative enhancement. For this purpose, known surface-engineering technologies such as painting, curtain coating, PVD or CVD coatings, or combinations of the techniques mentioned are used. PVD (Physical Vapor Deposition) is a coating process using physical vapor deposition. It is a group of vacuum-based coating methods or thin-film technologies in which the layer is formed directly by condensation of a material vapor of the starting material. CVD (English chemical vapor deposition) is understood to mean a coating process by means of chemical vapor deposition. In this case, a solid component is deposited on the heated surface of a substrate due to a chemical reaction from the gas phase. The above methods can be used to provide galvanized and metallic surfaces.
Das Zusammenfügen zwischen Dekorelement und Träger geschieht in der Regel mit bekannten Fügeverfahren wie Verrasten, Kleben, Schweißen oder durch mechanisches Verbinden wie Schrauben oder Nieten. Bei geringen Einbauhöhen stoßen die mechanischen Fügeverfahren jedoch an ihre technischen Grenzen. The assembly between the decorative element and the carrier is usually done with known joining methods such as locking, gluing, welding or by mechanical bonding such as screws or rivets. At low installation heights, however, the mechanical joining methods reach their technical limits.
Einen möglichen Fügeprozess mit geringem Platzbedarf stellt das Ultraschallschweißen dar, mit dem sowohl thermoplastische als auch metallische Bauteile schweißbar sind. Beim Ultraschallschweißen werden Ultraschallschwingungen in einem Generator erzeugt, welcher die eingehende Netzspannung in hochfrequente Energie umwandelt. Diese hochfrequente elektrische Energie wird über einen Schallwandler in mechanische Schwingungsenergie gleicher Frequenz umgewandelt. A possible joining process with a small footprint is the ultrasonic welding, with which both thermoplastic and metallic components are weldable. In ultrasonic welding ultrasonic vibrations are generated in a generator, which converts the incoming mains voltage into high-frequency energy. This high-frequency electrical energy is converted via a transducer into mechanical vibration energy of the same frequency.
Beim Ultraschallschweißen wird nun die zum Plastifizieren benötigte Wärme durch die Umwandlung von Ultraschallschwingungen in mechanische Schwingungen erzeugt und mit einem bestimmten Anpressdruck über den Schweißstempel, die sogenannte Sonotrode, dem zu schweißendem Werkstück und hier speziellen Verschweißgeometrien wie Laschen, Rippen oder Stegen zugeleitet. Die Kunststoffbauteile fungieren hier als Energieträger. In ultrasonic welding, the heat required for plasticizing is now generated by the conversion of ultrasonic vibrations into mechanical vibrations and fed with a certain contact pressure via the welding punch, the so-called sonotrode, the workpiece to be welded and here special Verschweißgeometrien as tabs, ribs or webs. The plastic components act here as energy sources.
Die auf das Werkstück auftreffenden mechanischen Schwingungen werden absorbiert und an der Grenzfläche reflektiert. Aufgrund der entstehenden Grenzflächen- und Molekularreibung entsteht Wärme, die den Kunststoff aufschmelzen und plastifizieren lässt. Die aufgeschmolzenen Werkstoffe verbinden sich und sind nach dem Abkühlen und Erstarren miteinander verschweißt. The mechanical vibrations impinging on the workpiece are absorbed and reflected at the interface. Due to the resulting interfacial and molecular friction, heat is generated which melts and plasticizes the plastic. The molten materials combine and are welded together after cooling and solidification.
Bei lackierten, foliendekorierten oder PVD-beschichteten Bauteilen funktioniert das Aufschmelzen der Bauteilabschnitte in Form von Laschen, Stegen oder Rippen meist problemlos; Overspray, also der Teil des aufgespritzten Materials, der nicht auf das Werkstück gelangt, sondern in Form von Sprühnebel in die Umgebung entweicht, oder sogar gänzlich lackierte zu verschweißende Geometrien haben keinen negativen Einfluss auf das Schweißergebnis. Ebenso stören PVD- oder CVD-Beschichtungen die Verschweißungen nicht bzw. verunreinigen das Schweißgut nicht dahingehend, dass die mechanische Stabilität der Verschweißung leidet. In painted, foil-decorated or PVD-coated components, the melting of the component sections in the form of tabs, webs or ribs usually works without problems; Overspray, ie the part of the sprayed material that does not get onto the workpiece but escapes into the environment in the form of spray mist, or even completely painted geometries to be welded have no negative influence on the welding result. Likewise, PVD or CVD coatings do not disturb the welds or do not contaminate the weld metal so that the mechanical stability of the weld suffers.
Das Verfügen galvanisierter Bauteile mit dem, meist mechanisch stabilen Träger stellt den Verarbeiter jedoch vor massive Probleme. The provision of galvanized components with the, usually mechanically stable carrier, however, presents the processor with massive problems.
Grund hierfür ist, dass auch auf den Bauteilabschnitten wie Laschen, Rippen und Stegen eine Galvanikschicht abgeschieden wird und diese Metallschicht ein Plastisch-werden der Bauteilabschnitte unter üblichen Bedingungen verhindert. Um ein Plastisch-Werden der Bauteilabschnitte zu erreichen, ist sehr viel Energie erforderlich, um die Galvanikschicht zu überwinden. Dadurch kommt es aber dann zu einem schlagartigen Plastisch-Werden, wodurch das innenliegende Kunststoffmaterial ggf. thermisch beschädigt wird. Ab einer gewissen Schwächung bricht die Geometrie des metallisch ummantelten Kunststoffkerns der Lasche, Rippe oder des Stegs zusammen. Problematisch für die Festigkeit der Verschweißung ist außerdem, dass sich im anschließenden Schweißgut thermisch geschädigtes Kunststoffmaterial und Reste der Galvanikschicht befinden, welche zu einer Inhomogenität des Schweißgutes und zu einer Verringerung der Verschweißung führen. The reason for this is that even on the component sections such as tabs, ribs and webs, a galvanic layer is deposited and this metal layer prevents the component sections from becoming plastic under normal conditions. In order to achieve plasticization of the component sections, a great deal of energy is required to overcome the electroplating layer. But then it comes to a sudden plastic becoming, whereby the internal plastic material is possibly thermally damaged. After a certain weakening breaks the geometry of the metallic coated plastic core of the tab, rib or the web together. Another problem for the strength of the weld is that in the subsequent weld metal thermally damaged plastic material and remnants of the electroplated layer are, which lead to an inhomogeneity of the weld metal and to a reduction of the weld.
Eine Abhilfemaßnahme in der Praxis ist es, die zu verschweißenden Geometrien am galvanisierten Kunststoffteil vor dem Verschweißen aufwändig mit einem galvanoinerten Lacksystem abzumaskieren. Dies ist in der Regel ein zusätzlicher Arbeitsgang, welcher Ausschuss durch Handhabungsfehler oder Verunreinigungen durch das eingesetzte Lacksystem mit sich bringen kann. Des Weiteren ist dieser zusätzliche Arbeitsgang mit zusätzlichen Kosten verbunden. A corrective measure in practice is to extensively mask the geometries to be welded on the galvanized plastic part before welding by means of a galvanized paint system. This is usually an additional operation, which can bring Committee by handling errors or contamination by the paint system used with it. Furthermore is This additional operation involves additional costs.
Eine weitere Möglichkeit die Verschweißgeometrien chromfrei und somit sicher verschweißbar darzustellen, ist der Einsatz der sogenannten Zwei-Komponenten-Spritzgusstechnik. Hier werden die zu verschweißenden Geometrien, an denen später der Schweißstempel angesetzt wird, aus einem galvanikinerten Kunststoffmaterial, also einem nicht galvanisierbaren Kunststoffmaterial, geformt, welche an das aus einem galvanisierfähigen Kunststoffmaterial gefertigten und später galvanisierten Dekorelement angespritzt werden. Dies erfordert jedoch einen aufwändigeren Zwei-Komponenten-Spritzgussprozess und spezielle Werkzeuge und Maschinen. All diese Maßnahmen bringen zwar den gewünschten Erfolg, also einen stabilen und sicheren Verschweißprozess; dieser ist jedoch auch deutlich teurer als ein konventioneller Spritzgussprozess. Another possibility to display the welding geometries chrome-free and therefore reliably weldable is the use of so-called two-component injection molding technology. Here, the geometries to be welded, at which the welding punch is applied later, are formed from a galvanic-inert plastic material, that is to say a non-galvanisable plastic material, which are molded onto the decorative element made of a galvanisable plastic material and later galvanized. However, this requires a more elaborate two-component injection molding process and special tools and machines. All these measures bring the desired success, ie a stable and secure welding process; However, this is also much more expensive than a conventional injection molding process.
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, Bauteilabschnitte wie Laschen, Rippen und Stege an galvanisierten Kunststoffbauteilen bereitzustellen, welche zum dauerhaften und prozesssicheren Fügen von Bauteilen aus wenigstens einem galvanisierten Bauteil mit einem nicht galvanisierten Bauteil mittels Ultraschallschweißprozess geeignet sind. Against this background, the invention has the object to provide component sections such as tabs, ribs and webs of galvanized plastic components, which are suitable for permanent and reliable assembly of components from at least one galvanized component with a non-galvanized component by means of ultrasonic welding process.
Gelöst wird diese Aufgabe gemäß der Erfindung dadurch, dass die freien Enden der Bauteilabschnitte derart geometrisch ausgestaltet sind, dass eine Metallabscheidung bei der galvanischen Beschichtung im Bereich der Konturen vermieden oder vermindert ist. This object is achieved according to the invention in that the free ends of the component sections are designed geometrically such that a metal deposition in the galvanic coating in the region of the contours is avoided or reduced.
Durch die spezielle geometrische Ausgestaltung der am galvanisierten Bauteil befindlichen Laschen, Rippen und Stege, welche zum dauerhaften und prozesssicheren Fügen von Bauteilen, wenigstens eines galvanisierten Bauteiles mit einem ungalvanisierten Bauteils mittels Ultraschallschweißprozess benötigt werden, ist eine Abschirmung hervorgerufen, wodurch eine verringerte bis gar keine Galvanikschicht abgeschieden wird. Dadurch ein übliches Verschweißen mittels Ultraschall ermöglicht. Due to the special geometric design of the galvanized component located tabs, ribs and webs, which are required for permanent and reliable assembly of components, at least one galvanized component with an ungalvanisierten component by means of ultrasonic welding process, a shield is caused, creating a reduced to no galvanic layer is deposited. This allows a usual welding by means of ultrasound.
