Description

Verfahren und Vorrichtung zur Umformung von thermoplastischen Kunststoffen Die Erfindung betrifft ein Verfahren zur Herstellung von Verformungen an Kunststoffteilen aus thermoplastischem tunststoff sowie eine Vorrichtung zur Durchführung dieses Verfahrens. Method and device for forming thermoplastics The invention relates to a method for producing deformations on plastic parts made of thermoplastic material and a device for performing this Procedure.

Es ist bekannt, Verformungen an Kunststoff teilen, beispielsweise die Anformung eines Nietkopfes an einen Kunststoffzapfen oder die Anformung eines Bördel an ein Kunststoffröhrchen, in der Weise herzustellen, daß man gegen die betreffende Stelle des Kunststoff teils einen die gevtinschte Form bestimmenden Stempel andrückt und den Kunststoff unter Zuführung von Wärme durch Heißluft oder durch einen mittels einer Heizeinrichtung beheizten Stempel. oder durch Erzeugung der Wärme durch Ultraschall weich macht oder aufschmilzt.It is known to share deformations on plastic, for example the molding of a rivet head on a plastic pin or the molding of a Flare on a plastic tube, manufacture in such a way that one against the relevant Place of the plastic part presses a stamp that determines the gevtinscht shape and the plastic with the supply of heat by hot air or by a means a heating device heated stamp. or by generating the heat using ultrasound softens or melts.

Diese Methoden sind wegen des erforderlichen apparativen Aufwandes und der relativ langen Aufschmelz- und Umfoxinungs-: zeiten für die Praxis unbefriedigend.These methods are because of the equipment required and the relatively long melting and Umfoxinungs- times unsatisfactory in practice.

Das erfindungsgemäße Verfahren vermeidet die Mängel der bekannten Methoden und besteht darin, daß die zu verformende Stelle des Kunststoffteils durch Andrücken eines rotierenden.The method according to the invention avoids the shortcomings of the known ones Methods and consists in that the point to be deformed by the plastic part Pressing a rotating.

Formgebungswerkzeugs aufgeschmolzen und gleichzeitig umgeformt wird, wobei Andruck und Rotationsgeschvindigkeit so bemessen werden, daß von dem Formgebungsverkzeug eine zum Aufschmelzen des Kunststoffmaterials ausreichende Reibungswärme erzeugt wird. Dieses Verfahren kann mit einem einfachen, drehsymetrischen Stempel als Formgebungswerkzeug und z.B.Forming tool is melted and formed at the same time, with pressure and rotation speed so be measured that one of the shaping tools is sufficient to melt the plastic material Frictional heat is generated. This process can be carried out with a simple, rotationally symmetrical Stamp as a shaping tool and e.g.

unter Verwendung einer gewöhnlichen Bohrmaschine durchgeführt werden und hat also den großen Vorteil, daß die benötligten Vorrichtungskosten sehr gering sind. Ein weiterer, erheblicher Vorteil besteht darin, daß sehr hohe Um£ormungsgeschwindigkeiten erzielt werden können und daß sich dadurch für eine serienmäßige Herstellung von Verformungen sehr kurze Taktzeiten eryeben. So kann man z.B. in sehr einfacher und wirtschaftlicher Weise und außerdem auch mit einem absolut festen, spannungsarmen Sitz Metallteile, wie z.B. Mutern, nachträglich in Kunststoffartikel einbetten und dadurch die bisherige unbefriedigende Methode vermeiden, solche Metallteile in Aussparungen des Kunststoffartikels mittels eines Klebers zu befestigen oder sogleich bei der Herstellung des Kunststoffartikels in das Kunststoffmaterial einzubetten, wozu die Metallteile in umständlicher Handarbeit in die Spritzgießform oder dergleichen eingelegt werden müssen. Der für die Praxis bedeutsame Vorteil und Nutzen des erfindungsgegen Verfahrens besteht darin, daß die an sich zum Aufschmelzen von Kunststoff, beispielsweise auch zur Herstellung von Schweißverbindungen zwischen zwei gleichartigen Thermoplasten bekannte Erzeugung von Reibungswärme direkt durch ein rotierendes Formgebungswerkzeug erfolgt und also unmittelbar mit der gleichzeitigen Formgebung stattfindet, vobei sich das erfindungsgemäße Verfahren für die verschiedensten rotationssymetrischen Formgebungen verwenden läßt.can be performed using an ordinary drill and thus has the great advantage that the device costs required are very low are. Another significant advantage is that very high deformation speeds can be achieved and that this allows for series production of Deformations allow very short cycle times. For example, in a very simple and economical way and also with an absolutely solid, low-tension Seat metal parts, such as nuts, can be subsequently embedded in plastic articles and thereby avoiding the previous unsatisfactory method of placing such metal parts in recesses to attach the plastic article by means of an adhesive or immediately at the Embed production of the plastic article in the plastic material, including the Metal parts inserted into the injection mold or the like by laborious manual work Need to become. The advantage and use of the counterpart of the invention, which is important in practice The method is that the per se for melting plastic, for example also for the production of welded connections between two thermoplastics of the same type known generation of frictional heat directly by a rotating molding tool takes place and thus takes place directly with the simultaneous shaping, vobei the inventive method for the most diverse rotationally symmetrical Can use shapes.

Das Verfahren kann in denkbar einfacher Weise mit einer Vorrichtung durchgeführt werden, die gekennzeichnet ist durch einen rotierend angetriebenen und in Richtung seiner Ro#ionsachse gegen das Kunststoffteil vordrückbaren Stempel,; dessen Reibungswärme erzeugendevmit dem Kunststoffmaterial zusammenwirkende Fläche vorzugsweise mit einer das Ankleben von aufgeschmolzenem Kunststoffmaterial verhindernden Oberfläche versehen ist, wobei der formabende Hohlraum an dem Stempel undjoder an einer-die zu verformende Stelle des Kunststoffteils umgebenden Gegenform angeordnet ist.The method can be carried out in a very simple way with a device be carried out, which is characterized by a rotating drive and stamps which can be pushed against the plastic part in the direction of its axis of rotation; its frictional heat generating surface interacting with the plastic material preferably with a sticking of melted plastic material to prevent Surface is provided, the molding cavity on the punch andjoder on a counter-shape surrounding the point of the plastic part to be deformed is.

Die Erfindung wird nachstehend anhand der Zeichnung näher erläutert, in der verschiedene Beispiele von Umformungen an Kunststoffteilen und die dazu benötigten Vorrichtungen in der Ansicht, teilweise im Schnitt, dargestellt sind.The invention is explained in more detail below with reference to the drawing, in the various examples of forming on plastic parts and the required Devices are shown in the view, partly in section.

Fig. 1 zeigt eine Form 1, in die ein Kunststoffröhrchen 2 eingespannt ist, dessen Ende mit einem Bördel versehen werden soll. Fig. 2 zeigt einen rotierend angetriebenen, in Richtung seiner Rotationsachse verschiebbaren Drehstempel 3, der durch Andrücken gegen das Kinststoffröhrchen 2 Reibung erzeugt und dadurch das Kunststoffmaterial aufschmilzt und gleichzeitig in den Formhohlraum 4 der Form 1 drückt. Dabei verhindert ein in das Röhrchen 2 hineinrage#nder Zapfen 5 des Drehstempels 3, daß das aufgeschmolzene #unststof£-material bei der Umformung in den lichten Querschnitt des Röhrchens entweicht. Fig. 3 zeigt das Röhrchen 2 mit fertig geformtem Flansch.Fig. 1 shows a mold 1 in which a plastic tube 2 is clamped is, the end of which is to be provided with a flange. Fig. 2 shows a rotating driven rotary ram 3 displaceable in the direction of its axis of rotation, the by pressing against the Kinststoffröhrchen 2 friction is generated and thereby the plastic material melts and at the same time presses into the mold cavity 4 of the mold 1. This prevented a pin 5 of the rotary punch 3 protruding into the tube 2, that the melted # plastic material during forming into the clear cross-section of the Tube escapes. Fig. 3 shows the tube 2 with a fully formed flange.

Fig. 4 zeigt zwei Kunststoffteile 7 und 8, die durch eine Nietverbindung miteinander verbunden werden sollen. Das Kunststoff teil 7 besitzt dazu einen durch das Kunststoffteil 8 hindurchragenden Zapfen 9. Fig. 5 zeigt einen Dreh-Stempel 10, dessen kalottenförmig gehöhlte Formgebungsfläche 11 das Kunststoffmaterial des Zapfens 9 durch'Reibungswärme aufschmilzt und durch den Andruck des Drehstempels zu einem Nietkopf umformt. Fig. 6 zeigt die beiden Kunststoffteile 7 und 8 mit dem fertig geformten Nietkopf 12.Fig. 4 shows two plastic parts 7 and 8, which by a rivet connection should be connected to each other. The plastic part 7 has a through the plastic part 8 protruding pin 9. FIG. 5 shows a rotary stamp 10, whose dome-shaped hollowed shaping surface 11 is the plastic material of the Pin 9 melts by'Reibungswärme and by the pressure of the rotary ram formed into a rivet head. Fig. 6 shows the two plastic parts 7 and 8 with the finished rivet head 12.

Fig. 7 zeigt ein Kunststoffteil 13, das mit einem in das Kunststofimaterial eingebetteten Metallteil 14, beispielsweise einer Mutter, versehen werden soll. Das Kunststoffteil 13 besitzt dazu eine Ausnehmung bzw. Bohrung 15, in die das Metallteil 14 eingelegt ist. Fig. 8 zeigt einen Drehstempel 16, dessen Durchmesser um einen bestimmten Betrag größer ist als der Durchmesser der Aussparung 15. Ferner besitzt der Drehstempel 16 einen passend in das Metallteil X eingreifenden Zapfen 17, der den lichten Querschnitt des Metallteils 14 vor etwaigem Eindringen von Kunststoffmaterial schützt. Durch Rotation und Andruck des Drehstempels 16 wird das Kunststoffmaterial am Rand der Aussparung 15 angeschmolzen und verformt, wodurch, wie Fig. 9 zeigt, einerseits eine im Durchmesser etwas größere Aussparung 18 entsteht und andererseits ein Bund 19, der das Metallteil 14 überlappt und es gegen Herausziehen aus dem Kunststoffteil 13 befestigt.Fig. 7 shows a plastic part 13 with a in the plastic material embedded metal part 14, for example a nut, is to be provided. For this purpose, the plastic part 13 has a recess or bore 15 into which the metal part 14 is inserted. Fig. 8 shows a rotary punch 16, the diameter of which by one certain amount is greater than the diameter of the recess 15. It also has the rotary punch 16 has a pin 17 which fits into the metal part X and which the clear cross section of the metal part 14 before any penetration of plastic material protects. By rotating and pressing the rotary ram 16, the plastic material melted and deformed at the edge of the recess 15, as a result of which, as FIG. 9 shows, on the one hand a recess 18 which is slightly larger in diameter is created and on the other hand a collar 19 which overlaps the metal part 14 and prevents it from being pulled out of the plastic part 13 attached.

Ist die Umfangsfläche des Metallteils 14 we im Falle einer Mutter ein Polygon und die Aussparung 15 eine zylindrische Bohrung, wird bei der Herstellung des Bundes 19 gleichzeitig Kunststoffmaterial in die Lücken am Umfang des Metallteils 14 gedrückt und dadurch das Metallteil 14 drehfest in das Kunststoffteil 13 eingebettet.Is the peripheral surface of the metal part 14 we in the case of a nut a polygon and the recess 15 a cylindrical bore is used in the manufacture of the federal 19 at the same time plastic material in the gaps on the circumference of the metal part 14 and thereby the metal part 14 is embedded in the plastic part 13 in a rotationally fixed manner.
