Description

Die Erfindung betrifft ein Hybridbauteilherstellungsverfahren.The The invention relates to a hybrid component manufacturing method.

Bauteile, die aus Metall und Kunststoff bestehen, werden als Hybridbauteile bezeichnet und sind im Stand der Technik bespielsweise durch die DE 10 2005 004 917 A1 für Fahrwerksbauteile bekannt. Sie zeichnen sich durch eine hohe Steifigkeit bei geringem Gewicht aus. Zur Herstellung von Hybridbauteilen können Kunststoffeinlegebauteile in metallischen Hohlbauteilen angeordnet werden. Die Kunststoffeinlegebauteile können eine Gitter- oder Rippenstruktur aufweisen.Components made of metal and plastic are referred to as hybrid components and are in the prior art recordable by the DE 10 2005 004 917 A1 known for suspension components. They are characterized by a high rigidity with low weight. For the production of hybrid components, plastic insert components can be arranged in metallic hollow components. The plastic insertion components may have a grid or rib structure.

Als nachteilig wird bei bekannten Hybribbauteilen angesehen, dass die Kunststoffeinlegebauteile nicht immer einwandfrei an den metallischen Blechbauteilen anliegen, weil die Radien der hohlen Pressteile variieren. Dies könnte beispielsweise dazu führen, dass im laufenden Betrieb eines Kraftfahrzeugs störende Klappergeräusche auftreten. Zudem sind die bekannten Verfahren zur Herstellung von Hybridbauteilen sehr aufwendig und kostenträchtig.When A disadvantage is considered in known Hybribbauteilen that the Plastic insert components are not always perfect on the metal Sheet metal components abut, because the radii of the hollow pressed parts vary. For example, this could result in the ongoing operation of a motor vehicle disturbing rattling noises occur. In addition, the known methods for the production of Hybrid components very expensive and costly.

Insbesondere das Verbinden von Bauteilen durch Spritzguss erfordert komplexe Maschinen und verursacht einen hohen Handhabungs- und Logistikaufwand aufgrund der Größe der metallischen Bauteile. Dies wird gerade bei der Massenfertigung von Automobilen als nachteilig angesehen.Especially the joining of components by injection molding requires complex Machines and causes a high handling and logistics effort due to the size of the metallic components. This is especially in the mass production of cars as disadvantageous considered.

Der Erfindung liegt die Aufgabe zu Grunde, ein Hybridbauteilherstellungsverfahren aufzuzeigen, welches eine rationelle Herstellung von hochwertigen Hybridbauteilen ermöglicht, die sich durch eine lange Lebensdauer auszeichnen.Of the The invention is based on the object, a hybrid component manufacturing method to show what a rational production of high-quality hybrid components which is characterized by a long service life.

Diese Aufgabe wird durch ein Verfahren mit den Maßnahmen von Patentanspruch 1 gelöst.These Task is performed by a procedure with the measures of Claim 1 solved.

Gemäß Patentanspruch 1 ist vorgesehen, zunächst ein Blechbauteil und ein Kunststoffeinlegebauteil, die jeweils Verbindungselemente aufweisen, separat herzustellen. Sodann wird an die Verbindungselemente des Kunststoffeinlegebauteils eine Kunststoffkomponente angespritzt. Im nächsten Schritt wird das Kunststoffeinlegebauteil am Blechbauteil über die Verbindungselemente fixiert. Abschließend wird die Kunststoffkomponente durch Erwärmung expandiert.According to claim 1 is provided, first a sheet metal component and a plastic insert component, each having connecting elements to produce separately. Then, to the connecting elements of the plastic insert molded on a plastic component. In the next step the plastic insert component on the sheet metal component over fixed the fasteners. In conclusion, the Plastic component expanded by heating.

Mit dem erfindungsgemäßen Verfahren kann das Hybridbauteil auf besonders rationelle Weise hergestellt werden. Zur Herstellung der einzelnen Bauteile können auf bestehende Fertigungsstrukturen zurückgegriffen werden. Eine Verwendung von aufwendigen Spritzgussmaschinen und Werkzeugen zum Anspritzen des Kunststoffs an das Blechbauteil ist nicht erforderlich. Durch die Kunststoffkomponente, die im abschließenden Verfahrensschritt expandiert wird, kann eine optimale Anpassung an die Radien der gepressten Blechbauteile erzeugt werden, so dass lästiges Klappern unterbleibt. Ein weiterer Vorteil ist, dass bei einem verschleißbedingten Auswaschen der Radien des Blechwerkzeugs, das Spritzgusswerkzeug nicht an die sich verändernde Geometrie des Blechwerkzeugs angepasst zu werden braucht. Dadurch ist das Abdichtproblem beim Spritzguss gelöst. Das Verfahren eignet sich daher insbesondere für die Massenfertigung von Automobilen.With the method according to the invention, the hybrid component be prepared in a particularly rational way. For the production The individual components can be based on existing manufacturing structures be resorted to. A use of elaborate Injection molding machines and tools for molding the plastic to the sheet metal component is not required. Due to the plastic component, which is expanded in the final process step, can be an optimal adaptation to the radii of the pressed sheet metal components be generated so that bothersome rattling is omitted. Another advantage is that with a wear-related Wash out the radii of the sheet metal tool, the injection molding tool not to the changing geometry of the sheet metal tool needs to be adjusted. This is the sealing problem in injection molding solved. The method is therefore particularly suitable for the mass production of automobiles.

Vorteilhafte Weiterbildungen des erfindungsgemäßen Verfahrens sind Gegenstand der abhängigen Ansprüche.advantageous Further developments of the method according to the invention are the subject of the dependent claims.

Besonders vorteilhaft ist es, wenn die Kunststoffkomponente durch einen Zwei-Komponenten-Spritzguss angespritzt wird. Der Zwei-Komponenten-Spritzguss ermöglicht das Anspritzen der Kunststoffkomponente in einem Arbeitsschritt.Especially It is advantageous if the plastic component by a two-component injection molding is injected. The two-component injection molding allows the injection of the plastic component in one step.

Das Kunststoffeinlegebauteil kann über Verbindungselemente in Form einer Schnappverbindung im Blechbauteil fixiert werden. Die Schnappverbindung ermöglicht eine besonders einfache und schnelle Fixierung des Kunststoffeinlegebauteils im Blechbauteil. Die hierzu erforderlichen Verbindungselemente können am Kunststoffeinlegebauteil und im Blechbauteil während des Herstellungsprozesses vorgesehen werden, ohne dass es dazu eines eigenen Arbeitsschrittes bedürfte. Die Fixierung des Kunststoffeinlegebauteils ist innerhalb eines Arbeitstaktes möglich. Durch Anwendung der Prinzipien des Poka Yoke kann das Kunststoffeinlegebauteil in der Form so gestaltet sein, dass eine fehlerhafte Fixierung mit an Sicherheit grenzender Wahrscheinlichkeit ausgeschlossen wird. Dies ist insbesondere unter den Bedingungen einer Massenfertigung vorteilhaft.The Plastic insert can via fasteners be fixed in the form of a snap connection in the sheet metal part. The snap connection allows a particularly simple and rapid fixation of the plastic insert component in the sheet metal component. The necessary fasteners can on Kunststoffeinlegebauteil and in the sheet metal component during the Be provided without any of this own step would need. The fixation of the plastic insert component is possible within one working cycle. By application The principles of Poka Yoke can be found in the plastic insert component the shape be designed so that a faulty fixation with almost certainly excluded. This is especially under the conditions of mass production advantageous.

In einer weiteren vorteilhaften Weiterbildung des Verfahrens wird die Kunststoffkomponente während des Aushärtprozesses einer kathodischen Tauchlackierung expandiert. Durch diese Maßnahme kann die Herstellung des Hybridbauteils vorteilhaft in den Herstellungsprozess einer Karosserie integriert werden. Die Herstellung des Blechbauteils und des Kunststoffeinlegebauteils können auch von Zulieferern übernommen werden ebenso wie das Anspritzen des expandierenden "Zweikomponenten-Spritzgusses" an die Verbindungselemente des Kunststoffeinlegebauteils. Im Rohkarosseriebau oder auch durch den Zulieferer erfolgt dann die Fixierung des Kunststoffeinlegebauteils am Blechbauteil über die Verbindungselemente. In der abschließenden Karosserielackierung, die vorzugsweise durch eine kathodische Tauchlackierung erfolgt, wird die Kunststoffkomponente im Rahmen des Aushärtprozesses expandiert und das Kunststoffeinlegebauteil fest im Blechbauteil verankert. Auf diese Weise wird ein einwandfreies Hybridbauteil bereitgestellt, das sich mit minimalem zusätzlichen Aufwand herstellen lässt.In a further advantageous development of the method, the plastic component is expanded during the curing process of a cathodic dip coating. By this measure, the production of the hybrid component can be advantageously integrated into the manufacturing process of a body. The production of the sheet metal component and the plastic insert component can also be taken over by suppliers as well as the injection molding of the expanding "two-component injection molding" to the connecting elements of the plastic insert component. In Rohkarosseriebau or by the supplier then takes place the fixation of the plastic insert component on the sheet metal component via the connecting elements. In the final body painting, which is preferably carried out by a cathodic dip coating, the plastic As part of the curing process, the component expands and the plastic insert component is firmly anchored in the sheet metal component. In this way, a perfect hybrid component is provided which can be produced with minimal additional effort.

Zweckmäßigerweise wird das Kunststoffeinlegebauteil mit dem Blechbauteil durch die Kunststoffkomponente zusätzlich verklebt. Dies führt zu einer Erhöhung der Lebensdauer des Hybridbauteils.Conveniently, is the plastic insert with the sheet metal component through the Plastic component additionally glued. this leads to to increase the life of the hybrid component.

Die Erfindung wird nachfolgend anhand eines in den Zeichnungen technisch vereinfacht dargestellten Ausführungsbeispiels näher erläutert. Es zeigen:The Invention is described below with reference to a in the drawings technically simplified embodiment shown in more detail explained. Show it:

1 ein Blechbauteil und ein Kunststoffeinlegebauteil, die zu einem Hybridbauteil verbunden werden 1 a sheet metal component and a Kunststoffeinlegebauteil, which are connected to a hybrid component

2 die Schritte des Verfahrens in einer schematischen Darstellung. 2 the steps of the method in a schematic representation.

In der 1 sind ein Blechbauteil 1 und ein Kunststoffeinlegebauteil 2 nebeneinander dargestellt. Diese werden durch das erfindungsgemäße Verfahren zu einem Hybridbauteil 3 verbunden. Das Blechbauteil 1 ist eine B-Säule eines Kraftfahrzeugs. Es handelt sich um ein Hohlbauteil in Form einer Schale 4, die mit einer Verstärkung aus Blech versehen sein kann. Bei dem Kunststoffeinlegebauteil 2 handelt es sich um eine Kunststoffgitterstrukur 5, die aus Streben 6 und Knoten 7 gebildet ist. An den äußeren Knoten 8 sind Verbindungselemente 11 in Form von Schnappverbindungselementen, sogenannte Clips, angeformt, die in Verbindungselementen im Blechbauteil 1 in Form von Rastöffnungen fixiert werden können.In the 1 are a sheet metal part 1 and a plastic insert 2 shown side by side. These become a hybrid component by the method according to the invention 3 connected. The sheet metal component 1 is a B pillar of a motor vehicle. It is a hollow component in the form of a shell 4 , which can be provided with a reinforcement made of sheet metal. In the plastic insert component 2 it is a plastic lattice structure 5 that out of aspiration 6 and knots 7 is formed. At the outer node 8th are fasteners 11 in the form of snap-on connection elements, so-called clips, formed in connecting elements in the sheet metal component 1 can be fixed in the form of detent openings.

Wie man insbesondere in der 2 besser erkennen kann, wird an die Verbindungselemente 11 an den äußeren Knoten 8 des Kunststoffeinlegebauteils 2 eine Kunststoffkomponente 9 beispielsweise durch einen Zwei-Komponenten-Spritzguss angespritzt. Anschließend wird das Kunststoffeinlegebauteil 2 in das Blechbauteil 1 eingeclipst. Im Rahmen einer abschließenden kathodischen Tauchlackierung wird während des Aushärtprozesses das Blechbauteil 1 stark erwärmt, um die chemische Vernetzung eines epoxidharzhaltigen Lacks zu bewirken. Diese Erwärmung wird genutzt, um zeitgleich die Kunststoffkomponente 9 zu expandieren. Die Kunststoffkomponente 9 legt sich an die Wandung 10 des Blechbauteils 1 an. Hierbei verbindet sie klebetechnisch das Kunststoffeinlegebauteil 2 mit dem Blechbauteil 1. Auf diese Weise wird ein Hybridbauteil 3 mit dauerhaft haltbarem Form- und Stoffschluss zwischen Kunststoffeinlegebauteil 2 und Blechbauteil 1 erzeugt.As in particular in the 2 can recognize better is to the fasteners 11 at the outer node 8th of the plastic insert component 2 a plastic component 9 molded for example by a two-component injection molding. Subsequently, the Kunststoffeinlegebauteil 2 in the sheet metal part 1 clipped. As part of a final cathodic dip painting during the curing process, the sheet metal component 1 strongly heated to cause the chemical crosslinking of an epoxy resin-containing paint. This heating is used to simultaneously the plastic component 9 to expand. The plastic component 9 lies down against the wall 10 of the sheet metal component 1 at. In this connection, it combines the plastic insert component with adhesive technology 2 with the sheet metal part 1 , In this way, a hybrid component 3 with permanently durable form and material connection between plastic insert component 2 and sheet metal component 1 generated.

Bei dem erfindungsgemäßen Verfahren wird es als besonders vorteilhaft angesehen, dass die Fertigung der Einzelkomponenten wesentlich einfacher ist als die spritztechnische Fertigung eines integrierten Hybridbauteils 3. Toleranzen des Blechbauteils 1 können durch die Expansion der Kunststoffkomponente 9 im Rahmen der kathodischen Tauchlackierung auf vorteilhafte Weise ausgeglichen werden. Das Blechbauteil 1 muss nicht an einer Spritzgussmaschine gehandhabt werden, wodurch Handlingkosten vermieden werden. Durch Expansion der Kunststoffkomponente 9 und dem dadurch erzeugten guten Form- und Stoffschluss werden spätere Klappergeräusche unterbunden.In the method according to the invention, it is considered to be particularly advantageous that the production of the individual components is much simpler than the injection molding production of an integrated hybrid component 3 , Tolerances of the sheet metal component 1 can be due to the expansion of the plastic component 9 can be compensated in an advantageous manner in the context of cathodic dip painting. The sheet metal component 1 does not have to be handled on an injection molding machine, thereby avoiding handling costs. By expansion of the plastic component 9 and the resulting good form and material connection later rattling noises are prevented.
