Description
Verfahren und Vorrichtung zur Verbindung von thermoplastischen Kunststoffpreß- oder -spritzteilen Bei Gegenständen, die aus Kunststoffen gepreßt oder gespritzt werden, hat man es bisher nach Möglichkeit vermieden, den Gegenstand aus mehreren Teilen herzustellen, die später durch Verleimung miteinander verbunden werden müssen.Method and device for the connection of thermoplastic Kunststoffpreß- or injection molded parts For objects that are pressed or injection-molded from plastics it has hitherto been avoided as far as possible to select the object from several Manufacture parts that have to be glued together later.
Äl it Rücksicht darauf. daß die Kunststoffe verhéiltnismäßig teuer sind, hat man ohnehin das Bestrelven, die Wandungen der herzustellenden Gegenstände so klein wie möglich zu halten. Damit ergibt sich, daß die Verbindungsflächen, die für eine Verleimung in ISetracht kommen konnten, sehr lilein sind. Man hat L(isullgsmittel, xvie Aceton und verschiedenste Leime zur Bindung von Kunststoffi>reß- oder -si)ritzteilen verwendet. I)as Ergebnis ist bisher unbefriedigend.Äl it consideration. that the plastics are relatively expensive are, one has the best-of-all anyway, the walls of the objects to be manufactured to keep it as small as possible. This means that the connecting surfaces that could come into consideration for gluing, are very purple. One has L (isullgsmittel, xvie acetone and a wide variety of glues for bonding plastic tears or scratches used. I) the result has so far been unsatisfactory.
Die Erfindung strebt es an, Kunststoffpreß- oder spritzteile miteinander in einfacher und sicherer Weise zu verbinden, und besteht in erster Linie darin, daß der eine zu verbindende Teil mit leichtem Druck gegen einen in Umdrehung zu versetzenden Teil gedrückt wird. Hierbei ist die Voraussetzung zu machen, daß thermoplastische Kunststoffe verwendet werden. Zwischen dem in Umdrehung befindlichen und dem nicht in Umdrehung befindlichen Teil entsteht an der beabsichtigten Verl)indungsnaht eine Reibungswärme, die zu einer Erweichung der Kunststoffteile an dieser Stelle führt. Es genügt hierbei, die beiden zu verbindenden Teile nur einen kurzen Augenblick unter einem gewissen Druck aneinanderzufügen, um die gewünschte Verbindungsstelle zu erhalten. The invention aims at plastic molded or injection-molded parts with one another to connect in a simple and safe manner, and primarily consists of that the one part to be connected with slight pressure against one in rotation offsetting part is pressed. The prerequisite here is that thermoplastic Plastics are used. Between the one in rotation and the one not part that is rotating is created at the intended connection seam Frictional heat, which leads to a softening of the plastic parts at this point. It is sufficient for the two parts to be connected only for a brief moment join together under a certain amount of pressure to create the desired joint to obtain.
Anschließend erfolgt sofort wieder eine Abkühlung unter den Erweichungspunkt der Kunststoffmasse, und im gleichen Augenblick sind die i)ei(len zu verbindenden Teile zu einem einheitlichen, monolithen Teil geworden. Selbst bei kleinen Ver- bindungsflächen wird ein Zusammenhalt der beiden Teile erzeugt, genau so, als wenn diese beiden Teile einheitlich aus Kunststoffen gepreßt oder gespritzt wären. Auch mit größerer Kraftanstrengung kunen die beiden Teile nicht wieder voneinander getrennt werden. Diese außerordentlich gute Ver-I>indung wird erzielt, ohne daß bisher notwendige l ösungs- oder Klebmittel erforderlich wären. It is then immediately cooled again to below the softening point the plastic mass, and at the same time the i) parts are to be connected Parts become a unified, monolithic part. Even with small binding surfaces a cohesion of the two parts is created, just as if these two Parts would be uniformly pressed or injected from plastics. Even with bigger ones Exertion cannot separate the two parts from each other again. This extraordinarily good connection is achieved without what was previously necessary Solvents or adhesives would be required.
Man kann nach dem Verfahren der Erfindung auch zwei Teile miteinander verbinden, von denen nur ein Teil aus Kunststoffen gepreßt oder gespritzt ist, sofern beim Zusammenfügen der beiden zu ver-I,indenden Teile die Reibungswärme erzeugt wird, die zur Erweichung des Kunststoffteils an der Verbindungsstelle notwendig ist. The method of the invention can also be used to combine two parts connect, of which only a part is pressed or injection-molded from plastics, provided that when the two parts to be joined are joined, the frictional heat is generated which is necessary to soften the plastic part at the connection point is.
In der Zeichnung sind Ausführungsbeispiele des Erfindungsgegenstanldes wiedergegeben, und zwar zeigt Fig. I den Längsschnitt eines Aufspanndorns, auf welchem zwei gepreßte Kunststoffhülsen miteinander verbunden werden, Fig. 2 einen senkrechten Schnitt durch die Vorrichtung, nach Fig. I mit der dazugehörigen Abschabvorrichtung, Fig. 3 einen nach dem Verfahren der Erfindung herzustellenden, aus drei Kunststoffteilen bestehenden Handgriff. The drawing shows exemplary embodiments of the subject matter of the invention reproduced, namely Fig. I shows the longitudinal section of a mandrel on which two pressed plastic sleeves are connected to one another, Fig. 2 a vertical one Section through the device according to Fig. I with the associated scraping device, 3 shows a three plastic parts to be produced by the method of the invention existing handle.
Der Dorn I weist einen aufgerauhten Teil 2 und ein verjüngtes Ende 3 auf. Dieser Dorn wird an dem Schaft 4 durch eine beliebige, nicht darge stellte Antriebsvorrichtung in der mit dem eingezeichneten Pfeil angedeuteten Drehrichtung in Umdrehung versetzt. The mandrel I has a roughened part 2 and a tapered end 3 on. This mandrel is placed on the shaft 4 by any, not illustrated Drive device in the direction of rotation indicated by the arrow offset in rotation.
Die Kunststoffhülse 5 wird auf den aufgerauhten Teil 2 des Dorns I aufgesetzt und an den als Anschlag dienenden Bund 6a des Dorns I herangeschoben. Die Aufrauhung des Teils 2 des Dorns I dient dazu, um die Mitnahme der Kunststoffhülse 5 l>ei der Umdrehung des Dorns zu sichern. Alsdann wird von Hand die Kunststoffhülse 6 über die Verjiingung 3 des Dorns I mit verhältnismäßig leichtem Druck in Richtung des eingezeichneten Pfeils gegen die in Umdrehung versetzte Kunststoffhülse 5 geführt. Hierbei dient der Übergang des Teils 2 zu dem Teil 3 des Dorns I als Führung für die Kunststoffhülse 6. The plastic sleeve 5 is on the roughened part 2 of the mandrel I put on and pushed up against the collar 6a of the mandrel I serving as a stop. The roughening of the part 2 of the mandrel I is used to drive the plastic sleeve 5 l> one turn of the mandrel. Then the plastic sleeve is made by hand 6 over the Verjierung 3 of the mandrel I with relatively light pressure in the direction of the arrow drawn against the plastic sleeve 5 which has been set in rotation. Here, the transition from part 2 to part 3 of the mandrel I serves as a guide for the plastic sleeve 6.
Nach kurzer Zeit tritt durch die entstehende Reibungswärme an der Verbindungsnaht 7 eine iE:rweichung der Kunststoffmasse der beiden Hülsen 5 und 6 ein. Der von Hand ausgeübte Druck auf die Hülse 6 in der Axialrichtung des Dorns I wird sofort aufgegeben. Es tritt anschließend unmittelbar wieder eine Abkühlung an der Verbindungsnaht 7 ein, und die beiden Hülsen 5 und 6 sind ohne Verwendung von Leim, Lösungsmittel od. dgl. zu einer Einheit geworden. After a short time, the resulting frictional heat affects the Connecting seam 7 is a softening of the plastic compound of the two sleeves 5 and 6 a. The pressure exerted by hand on the sleeve 6 in the axial direction of the mandrel I will be given up immediately. Cooling then occurs again immediately at the connecting seam 7, and the two sleeves 5 and 6 are not used of glue, solvent or the like. Has become a unit.
Aus Fig. 2 ist zu erkennen, daß oberhalb des Dorns um die Achse 8 ein Abschabmesser g schwenkbar ist. Beim Andrücken der Hülse 6 gegen die Hülse 5 und bei dem damit sich ergebenden Erweicl1en der Kunststoffmasse an der Verbindungsnaht 7 kann nach außen ein Grat der erleichten Kunststoffmasse austreten. Das Entfernen dieses Grats ist schnell und einfach durchführbar, wenn noch während der Erweichung der Kunststoffmasse an der Verhindungsnaht 7 mit Hilfe der Schneidkante 10 des nach unten abgeklappten Ahschabmessers g dieser austretende Grat entfernt wird. Eine weitere Halleli)earl)eitullg der beiden miteinander verbundenen Kunststoffhülsen 5 und 6 ist nicht erforderlich. From Fig. 2 it can be seen that above the mandrel about the axis 8 a scraper g is pivotable. When the sleeve 6 is pressed against the sleeve 5 and with the resulting softening of the plastic compound at the connection seam 7 a ridge of the lighter plastic mass can emerge to the outside. The removal this ridge is quick and easy to do if still during softening the plastic mass at the connecting seam 7 with the help of the cutting edge 10 of the after This emerging burr is removed with the folded-down Ahschabmesserers g. One further halleli) earl) eitullg of the two interconnected plastic sleeves 5 and 6 is not required.
Nach Fig. 3 besteht der im Längsschnitt dargestellte Handgriff aus der Scllaftllülse 1 1 und den beiden Kugelhälften 12 und 13. Zwischen den Kugelhälften I2 und 13 gestellt die Verbindungsnaht 14, und zwischen der Kugelhälfte I2 und der Schafthülse II l)este'ht die Verbindungsnaht I5. According to Fig. 3, the handle shown in longitudinal section consists of of the sleeping sleeve 1 1 and the two halves of the ball 12 and 13. Between the halves of the ball I2 and 13 put the connecting seam 14, and between the ball half I2 and the Shaft sleeve II l) creates the connecting seam I5.
Zwecks Herstellung des T-Iandgrifts geht man so vor, daß zunächst die Schafthülse 1 1 auf einen Dorn aufgesetzt wird, der in Umdrehung versetzt ist. Alsdann wird von Hand die Kugelhälfte I2 gegen die sich drehende Schafihülse 1 1 gedrückt, und es entsteht an der Verbindungsnaht I5 eine Verwindung der Teile rI und 12. Anschließend wird die Schafthülse 1 1 zusammen mit der Kugelhälfte 12 in Umdrehung versetzt, und nunmehr wird die Kugelhälfte 13 gegen die sich drehende Kugelhälfte 12 gedrückt. Die Kugelhälften I2 und 13 werden hierdurch zu einer Einheit mit der Verbindungsuaht 14.For the production of the T-Landgrift one proceeds in such a way that first the shaft sleeve 1 1 is placed on a mandrel that is rotated. The ball half I2 is then pressed against the rotating sheep sleeve 11 by hand pressed, and there is a twisting of the parts rI at the connecting seam I5 and 12. Then the shaft sleeve 1 1 together with the ball half 12 in Rotation offset, and now the ball half 13 is against the rotating Ball half 12 pressed. The halves of the ball I2 and 13 thereby become one unit with the connecting seam 14.
An diesem Beispiel zur Herstellung eines Handgriffs, der z. B. bei NVerkzeugmaschinen Verwendung finden kann, erkennt man die besondere Bedeutung der Erfindung. 13isher wurden derartige Kugelhandgriffe vielfach aus dem vollen Material hergestellt, weil es bei Verwendung von Kunststoffmasse nicht möglich ist, den Handgriff aus einem Stück als Hohlkörper auszubilden. Gemäß der Erfindung wird somit bei der Herstellung derartiger Handgriffe in erheblichem Ausmaß an Kunststoff-Rohstoff gespart. Dieses Beispiel läßt erkennen, daß die Erfindung es ermöglicht, wesentlich komplizierter aufgebaute Gegenstände aus Kunststoffmasse herzustellen, als dies bisher der Fall war, wobei die hierzu erforderlichen Preß-oder Spritzformen eine sehr beachtliche Vereinfachung erfahren können. In this example for the production of a handle that z. B. at N machine tools can be used, one recognizes the special importance of Invention. Up to now, such ball handles were often made from the solid material produced because it is not possible to use the handle when using plastic compound in one piece as a hollow body. According to the invention is thus in the Production of such handles saves a considerable amount of plastic raw material. This example shows that the invention makes it possible to make things much more complicated to produce built-up objects from plastic mass than has previously been the case was, the compression or injection molds required for this a very considerable one Can experience simplification.
Als weiteres Ausführungsbeispiel für die Anwendung der Erfiiilnng Inag noch die Herstellung von Schwimmern für Klosettspülkästen genannt werden. Derartige Schwimmer wurden bisher aus Blech hergestellt, und die Verbindungsnähte mußten sorgfältig verlötet werden. Nach der Erfindung lassen sich derartige Schwimmer aus zwei Kunststoffhälften in einfachster Weise als Hohlkörper ausbilden. Das Verfahren der Erfindung ist auch hier wertvoll, weil die durch Reibungswärme erzeugte Verbindungsnaht der beiden Schwimmerhälften eine unbedingt dichte Verwindung dieser beiden Hälften herbeiführt. As a further embodiment for the application of the invention Inag the manufacture of floats for toilet cisterns can also be mentioned. Such Up to now, floats were made of sheet metal and the seams had to be carefully sewn be soldered. According to the invention, such floats can be made from two plastic halves in the simplest possible way as a hollow body. The method of the invention is also valuable here because the joint between the two created by frictional heat Float halves creates an absolutely tight twist of these two halves.
Die Erfindung ist ferner mit Erfolg anwendbar für Ampullen, die zur Aufnahme von z. B. Feuerzeugbenzin, Medikamenten usw. dienen. Diese Ampullen können im Sinne d r Erfindung aus zwei Teilen hergestellt werden, die quer zu ihrer Längsachse in der besc1lriel)el1ell Weise durch Reibungs- wärme miteinander verbunden werden. Als Rohstoff zur Herstellung dieser Ampullenteile empfehlt es sich, Polyäthylen zu verwenden, welches ein hochpolymeres Äthylen vom Molekulargewicht etwa 20 000 bis 25 000 darstellt. Dieser Kunststoff ist preß- und spritzbar, einzelne Teile dieses Kunststoffs lassen sich erfindungsgemäß durch Reibungswärme miteinander verbinden. Dieser Kunststoff ist gerade für Ampullen deshalb besonders geeignet, weil er bei Raumtemperatur in allen bisher l>ekannten Lösungsmitteln unlöslich ist. Außerdem lwat dieser Kunststoff die Eigenart elastisch zu bleiben, so daß das allmähliche Entfernen der jeweiligen Flüssigkeit aus der Ampulle erleichtert wird. The invention can also be used with success for ampoules which are used for Recording of z. B. lighter fluid, medicines, etc. are used. These ampoules can in the sense of the invention are made of two parts that are transverse to their longitudinal axis in the same way by frictional warm to each other get connected. It is recommended as a raw material for the production of these ampoule parts to use polyethylene, which is a high polymer ethylene of molecular weight represents about 20,000 to 25,000. This plastic can be pressed and injected individually According to the invention, parts of this plastic can be connected to one another by means of frictional heat associate. This plastic is particularly suitable for ampoules, because at room temperature it is insoluble in all previously known solvents is. In addition, this plastic has the peculiarity of remaining elastic, so that Gradual removal of the respective liquid from the ampoule is facilitated.
