Description
Die vorliegende Erfindung betrifft einen selbststanzenden Befestiger sowie eine Vorrichtung zum Verbinden des selbststanzenden Befestigers durch Stanzen und Umbördeln mit einem dünnwandigen Kunststoffteil.The The present invention relates to a self-piercing fastener and a device for connecting the self-piercing fastener Punching and beading with a thin-walled Plastic part.
Es ist bekannt, Kunststoffteile mittels Hülsen oder Buchsen lokal zu verstärken, um Anbauteile an dem Kunststoffteil beispielsweise mittels einer Schraubverbindung anzubringen. Entsprechend verstärkte Kunststoffteile werden in zahlreichen Bereichen der Industrie benötigt. Beispielsweise handelt es sich bei derartigen Kunststoffteilen um Strukturbauteile in der Fahrzeugindustrie wie Fußgängerschutz, Unterfahrschutz, Multifunktionswannen, Staufächer, Ölwannen, Unterbodenverkleidungen, etc.It It is known to plastic parts by means of sleeves or bushings locally strengthen to attachments to the plastic part, for example by means of a screw connection to install. Accordingly strengthened Plastic parts are needed in many areas of industry. For example Such plastic parts are structural components in the automotive industry such as pedestrian protection, Underride protection, multifunctional pans, storage compartments, oil pans, underbody coverings, etc.
Zu diesem Zweck sind Befestiger in Form buchsenförmiger Kaltfließpressteile bekannt, die in geformte oder gestanzte Löcher der Kunststoffteile kalt eingepresst werden. Die vorbekannten Lösungen sind jedoch im Hinblick auf verschiedene Anforderungen wie Wirtschaftlichkeit, geringe Herstellungs- und Montagekosten, Umweltverträglichkeit, Verbindungsqualität, Platzbedarf u.a. verbesserungsfähig.To For this purpose, fasteners in the form of bush-shaped Kaltfließpressteile known to cold in molded or punched holes of the plastic parts be pressed. However, the previously known solutions are in view to various requirements such as economy, low manufacturing and assembly costs, Environmental compatibility, quality of connection, space requirement et al improvement.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen selbstanzenden Befestiger sowie eine Vorrichtung zum Verbinden des selbststanzenden Befestigers mit einem Kunststoffteil durch Stanzen und Umbördeln zu schaffen, die sich durch hohe Wirtschaftlichkeit, insbesondere einfache Herstellbarkeit und Montage, sowie durch sehr gute Qualität der Verbindung zwischen dem Befestiger und dem Kunststoffteil auszeichnen.Of the present invention is based on the object, a self-staring Fastener and a device for connecting the self-piercing Fastener with a plastic part by punching and flanging too create, characterized by high efficiency, especially simple Manufacturability and assembly, as well as very good quality of the connection between the fastener and the plastic part.
Der selbststanzende Befestiger gemäß der vorliegenden Erfindung ist in Anspruch 1 definiert. Die Vorrichtung zum Verbinden des selbststanzenden Befestigers mit dem Kunststoffteil ist in Anspruch 14 definiert.Of the Self-piercing fasteners according to the present invention The invention is defined in claim 1. The device for connecting of the self-piercing fastener with the plastic part is in claim 14 Are defined.
Der erfindungsgemäß ausgebildete selbststanzende Befestiger, der durch Stanzen und anschließendes Umbördeln mit dem dünnwandigen Kunststoffteil verbindbar ist, besteht aus einem hülsenförmigen Hohlkörper mit einer Durchgangsbohrung, deren Innenwand als Funktionsteil ausgebildet ist. Der Hohlkörper weist einen Schaft und einen Kopf auf, von denen der Kopf an einem axialen Ende des Schaftes vorgesehen ist und der Schaft an seinem anderen axialen Ende einen umbördelbaren Bereich mit einer Schneidkante zum Durchstanzen des Kunststoffteils hat.Of the formed according to the invention Self-piercing fastener by punching and then crimping with the thin-walled plastic part is connectable, consists of a sleeve-shaped hollow body with a through hole whose inner wall is formed as a functional part. The hollow body has a shaft and a head, of which the head on a axial end of the shaft is provided and the shaft at its other axial end a beadable Area with a cutting edge for punching through the plastic part Has.
Der erfindungsgemäß ausgebildete selbststanzende Befestiger ist ein einfaches und kostengünstig herstellbares Bauteil, das auf wirtschaftliche Weise mit dem Kunststoffteil verbunden werden kann. Hierzu ist lediglich erforderlich, dass der Schaft des Befestigers in einem einfachen Stanzvorgang durch das Kunststoffteil getrieben wird und anschließend der über das Kunststoffteil überstehende Bereich des Befestigers auf das Kunststoffteil umgebördelt wird.Of the formed according to the invention Self-piercing fastener is a simple and inexpensive to produce Component that is economically connected to the plastic part can be. For this it is only necessary that the shank of Fastener in a simple punching process through the plastic part is driven and subsequently the over the plastic part protruding Area of the fastener is crimped to the plastic part.
Die erfindungsgemäß ausgebildete Vorrichtung zum Verbinden des selbststanzenden Befestigers weist auf: einen antreibbaren Setzstempel, der auf einer Seite des Kunststoffteils angeordnet ist und zum Setzen des selbststanzenden Befestigers im Kunststoffteil dient, einen Zapfen, der dem Setzstempel zugeordnet - und in die Durchgangsbohrung des Befestigers einführbar ist, um beim Setzvorgang den Befestiger zu halten und zusammen mit dem Befestiger das Kunststoffteil zu durchstanzen, eine Matrize, die auf der dem Setzstempel gegenüberliegenden Seite des Kunststoffteils angeordnet und mit einem Loch versehen ist, das den umbördelbaren Bereich des Befestigers beim Setzvorgang aufnimmt, und einen Bördelstempel, der auf der dem Setzstempel gegenüberliegenden Seite angeordnet ist und einen Vorsprung mit einer vorgegebenen Kontur hat, um nach dem Setzvorgang und Entfernen der Matrize den umbördelbaren Bereich des Befestigers auf das Kunststoffteil umzubördeln.The formed according to the invention Device for connecting the self-piercing fastener has on: a drivable setting stamp, on one side of the plastic part is arranged and for setting the self-piercing fastener in the plastic part serves, a pin, which is assigned to the setting stamp - and in the Through hole of the fastener is inserted to the setting process to hold the fastener and together with the fastener the plastic part to punch, a die, on the opposite side of the set temple the plastic part is arranged and provided with a hole, that the umbördelbaren Area of the fastener during the setting process receives, and a crimping, the arranged on the opposite side of the set temple is and has a projection with a given contour to go to the setting process and removing the die the umbördelbaren Flanging the area of the fastener onto the plastic part.
Mit dieser Vorrichtung kann der erfindungsgemäß ausgebildete selbststanzende Befestiger schnell und funktionssicher mit dem Kunststoffteil verbunden werden. Der Setzstempel treibt den Schaft des Befestigers sowie den vom Befestiger aufgenommenen Zapfen in einem einzigen Stanzvorgang durch das Kunststoffteil, bis der Kopf des Befestigers ein weiteres Eindringen des Befestigers in das Kunststoffteil verhindert. Anschließend wird der über das Kunststoffteil hinaus ragende Bereich des Befestigers von dem Bördelstempel auf das Kunststoffteil umgebördelt, wodurch der Befestiger im Kunststoffteil festgelegt ist und seine Funktion als buchsenförmige Verstärkung des Kunststoffteils ausüben kann.With This device can be inventively designed self-piercing Fastener quickly and functionally connected to the plastic part become. The Setzstempel drives the shank of the fastener as well the pin received by the fastener in a single punching operation through the plastic part until the head of the fastener another Penetration of the fastener in the plastic part prevented. Subsequently, will the over the plastic part outwardly projecting portion of the fastener of the flanging flanged over to the plastic part, whereby the fastener is fixed in the plastic part and its Function as a socket-shaped reinforcement exercise the plastic part can.
