Description

Verfahren zur Bildung- von Nietköpfen von Nieten aus einem warmgereckten thermoplastischen Isolierstoff, insbesondere Polystyrol Es ist zum gegenseitigen Vern,ieten von Platten- aus gehärtetem Kunstharz od. dgl. bekannt, Niete aus mit ungehärtetem Kunstharz getränkten Faserstoffen zu verwenden, die nach Einführen in die Nietlöcher durch einen geheizten Preßstempel unter Bildung von Nietköpfen zusammengestaucht werden wobei der Preßstempel so lange in der Preßstellung gehalten wird, bis das Kunstharz gehärtet ist und damit die Niete itl den festen Zustand übergeführt sind. Dieses Verfahren erfordert aber längere Erwärmungszeiten sowie besondere Preßformen und geheizte Werkzeuge und ist daher im allgemeinen als unwirtschaftlich anzusehen. Ferner sind zur Verbindung von Bauteilen der Rundfunk- und Hodfrequenztechnik Niete aus Poluvinylverbindungen, insbesondere aus Polystyrol bekannt. die durch Erwärmung bildsam gemacht werden können. Nach einem weiteren bekannten Vorschlag sollen Rondensatorbelegungen durch Niete aus Isolierstoff. beispielsweise aus gerecktem Polystyrol, zusammengehalten werden, wobei ebenfalls an eine Nietkopfbildung und ein Vernieten durch Warmpressen gedacht war. Auch derartige Warmpressungen erfordern besondere Preßformen bzw. geheizte Werkzeuge.Process for the formation of rivet heads from rivets from a hot-stretched material thermoplastic insulating material, especially polystyrene It is mutual Vern, ieten of plates made of hardened synthetic resin or the like. Known, rivets with Unhardened synthetic resin impregnated fibers to be used after introduction into the rivet holes through a heated ram to form rivet heads are compressed, the ram being held in the pressing position for so long is until the synthetic resin has hardened and thus the rivet itl the solid state are convicted. This procedure, however, requires longer heating times as well special molds and heated tools and is therefore generally considered uneconomical to watch. Furthermore, for the connection of components of the radio and testicular frequency technology Rivets made from poluvinyl compounds, in particular from polystyrene, are known. by Warming can be made plastic. According to another well-known suggestion should be covered by rivets made of insulating material. for example from stretched Polystyrene, are held together, also at a rivet head formation and riveting by hot pressing was intended. Such hot pressings also require special molds or heated tools.

Gemäß der Erfindung werden zur Bildung von Nietköpfen bei Nieten aus einem warmgereckten und in diesem Zustand abgekühlten thermoplastischen Isolierstoff, insbesondere Polystyrol (Styroflex), die Nietenden kurzzeitig durch eine Flamme erhitzt. Versuche mit Nieten aus warmgerecktem Polystyrol haben überraschenderweise gezeigt, daß eine kurzzeitige Einwirkung einer Flamme auf das Nietende genügt. um einen gleichmäßig abgerundeten Nietkopf zu bilden. According to the invention are used to form rivet heads in rivets made of a thermally stretched thermoplastic insulating material that has cooled down in this state, especially polystyrene (Styroflex), the rivet ends briefly by a flame heated. Experiments with rivets made of hot-stretched polystyrene have surprisingly shown that a brief exposure of a flame to the end of the rivet is sufficient. around to form an evenly rounded rivet head.

Dies ist darauf zurückzuführen, daß durch die Einwirkung der Flamme eine Entreckung des warmgereckten Äfaterials eintritt. Wegen der nur kurzzeitigen Erwärmung ist es mittels des erfindungsgemäßen Verfahrens sogar möglich. wärmeempfindliche Teile aus Leder od. dgl. miteinander zu vernieten.This is due to the fact that by the action of the flame a stretching of the warm-stretched Äfmaterials occurs. Because of the short-term Heating is even possible by means of the method according to the invention. heat sensitive Parts made of leather or the like to be riveted together.

Vorteilhaft werden die Niete aus einem längeren Faden auf die erforderliche Länge geschnitten und nach Einführen der Fadenstücke in die Nietlöcher beide Nietköpfe gleichzeitig gebildet. Für viele Anwen dungszwecke wird das Verfahren noch wirtsdaftlicher. wenn man den Faden in das Nietloch einführt und erst darauf das Schneiden dier Niete auf die erforderliche Länge vornimmt. In vielen Fällen wird es auch möglich und zweckmäßig sein. das Einführen des Fadens unmittelbar im Anschluß an die Bildung des Nietloches vorzunehmen. Es ergibt sich dann ein kontinuierliches Verfahren, das zusammengefaßt darin besteht. daß die Bildung des Nietloches, das Einführen des Fadens in das Nietloch. das Abschneiden des Fadens auf die erforderliche Länge und die Bildung beider Nietköpfe im gleichen Arbeitsgang erfolgt. The rivets are advantageous from a longer thread to the required Cut to length and after inserting the pieces of thread into the rivet holes, both rivet heads formed at the same time. The process is even more economical for many applications. when you insert the thread into the rivet hole and only then cut the rivet to the required length. In many cases it also becomes possible and be appropriate. inserting the thread immediately after formation of the rivet hole. The result is a continuous process, which, in summary, consists in this. that the formation of the rivet hole, the insertion of the thread into the rivet hole. cutting the thread to the required length and the formation of both rivet heads takes place in the same operation.

Die Erfindung ist an Hand der Zeichnung näher erläutern. The invention is explained in more detail with reference to the drawing.

Die Fig. 1 und 2 deuten das Verfahren gemäß der Erfindung im Prinzip an. Es ist angenommen. daß zwei Platten 10 und 11 aus Metall oder aus einem Isolierstoff, wie Leder od. dgl., miteinander vernietet werden sollen. Nach der Fig. 1 wird durch die Nietlöcher der beiden Platten ein Fadenstück 12 aus gerecktem Polystyrol solcher Länge eingeführt, daß aus den vorstehenden Enden Nietköpfe gebildet werden können. Durch kurzzeitige Erwärmung der Enden des Fadenstückes 12 mittels der Flammen 13 wird das Material zum Schmelzen gebracht und es bilden sich, wie in der Fig. 2 dargestellt, Nietköpfel4, die auch die konischen Erweiterungen der Nietlöcher ausfüllen. Figs. 1 and 2 show the method according to the invention in principle at. It is accepted. that two plates 10 and 11 made of metal or an insulating material, like leather or the like, to be riveted together. According to Fig. 1 is through the rivet holes of the two plates a piece of thread 12 made of expanded polystyrene such Length introduced that rivet heads can be formed from the protruding ends. By briefly heating the ends of the thread piece 12 by means of the flames 13 the material is brought to melt and it forms, as shown in Fig. 2, Rivet heads4, which also fill the conical enlargements of the rivet holes.

An Hand der Fig. 3 wird ein Verfahren zur Bildung einer fortlaufenden Nietreihe erläutert, wobei die Bildung der Nietlöcher, das Einführen eines Fadens in das Nietloch, das Abschneiden des Fadens auf die erforderliche Länge und die Bildung heider Nietköpfe im gleichen Arbeitsgang erfolgt. Die beiden miteinander zu vernietenden Teile 10 und 11 werden in der Pfeilrichtung durch die zur Ausführung des Verfahrens gemäß der Erfindung vorgesehene Einrichtung hindurchgeführt. Die Bildung delr Nietlöcher geschieht durch den Dorn 15, der mit dem Kurbelrad 16 durch die Pleuelstange 22 verbunden ist und durch Drehung des Kurbelrades in eine hin- und hergehende Bewegung gebracht wird. Der Faden 17, aus dem die Niete gebildet werden, wird von deir Vorratstrommel 18 abgewickelt. Der Dorn 15 ist mit den Klemmbacken 19 durch die gestrichelt angedeutete Verbindung 20 zwangläufig gekuppelt. Durch Bewegung des Dornes 15 nach links wird ein Nietloch durch die beiden plattenförmigen Teile 10 und 11 gedrückt. Bei Rückführung des Dornes, d. h. bei Bewegung des Dornes von links nach rechts, ergreifen die Klemmbacken 19 den Faden 17 und führen diesen in das Nietloch. Ist der Faden genügend weit durch das Nietloch hindurchgeführt, wird das zur Bildung eines Niets benötigte Fadenstück mittels des Messers 21 abgeschnitten. Die Bewegung des Messers ist zweckmäßig ebenfalls mit dem Kurbelrad 16 zwangläufig gekuppelt. Auf diese Weise werden bei Fortbewegung der beiden Teile 10111 aufeinanderfolgend die Nietlöcher gebildet und in diese die Fadenstücke 12 eingeführt. Die beiden Teile 10/11 mit den eingeführten Fadenstücken 12 werden anschließend an den beiderseits angeordneten Flammen 13 vorbeigeführt, durch die die gewünschten Nietköpfe gebildet werden. Die Flammen 13 werden hinsichtlich ihrer Wärmeeinwirkung auf die Enden der Fadenstücke 12 so bemessen und eingestellt, daß die erforderliche Erhitzungszeit mit der Umdrehungszeit des Kurbelrades 16 übereinstimmt. With reference to Fig. 3, a method for forming a continuous Row of rivets explained, the formation of the rivet holes, the insertion of a thread into the rivet hole, cutting the thread to the required length and the Both rivet heads are formed in the same operation. The two together Parts 10 and 11 to be riveted are indicated in the direction of the arrow by the of the method according to the invention provided device passed through. the The rivet holes are formed by the mandrel 15, which is connected to the crank wheel 16 the connecting rod 22 is connected and by turning the crank wheel in a reciprocating and moving movement is brought about. The thread 17 from which the rivet is formed is unwound from deir supply drum 18. The mandrel 15 is with the jaws 19 necessarily coupled by the connection 20 indicated by dashed lines. By Movement of the thorn 15 to the left is a rivet hole through the two plate-shaped parts 10 and 11 pressed. When returning the mandrel, i. H. at Moving the mandrel from left to right, the jaws 19 grip the thread 17 and lead it into the rivet hole. Is the thread far enough through the rivet hole passed through, the piece of thread required to form a rivet is by means of the Knife 21 cut off. The movement of the knife is also useful the crank wheel 16 inevitably coupled. This way you will be able to move around of the two parts 10111 successively formed the rivet holes and in this the Thread pieces 12 introduced. The two parts 10/11 with the inserted pieces of thread 12 are then led past the flames 13 arranged on both sides, through which the desired rivet heads are formed. The flames 13 are regarding their heat effect on the ends of the thread pieces 12 so dimensioned and adjusted, that the required heating time corresponds to the rotation time of the crank wheel 16.

Mittels des Verfahrens gemäß der Erfindung können Teile aus beliebigen Werkstoffen miteinander vernietet werden. Das Verfahren bietet besondere Vorteile in den Fällen, in denen die Niete aus Isolierstoff bestehen sollen, z. B. bei der gegenseitigen Vernietung von Kondensatorbelegungen. Mit besonderem Vorteil ist das Verfahren zur Bildung von elastischen Nietverbindungen für Werkstoffe aus elastischem Material, z. B. aus Leder oder einem lederartigen Kunststoff, anwendbar, weil die aus einem elastischen Isolierstoff bestehenden Niete eine gewisse Elastizität aufweisen. Beispielsweise können nach diesem Verfahren Lederteile für Schuhe, Taschen usw. miteinander vernietet werden. Zweckmäßig dürfte es sein, die zu vernietenden Teile an der Nietstelle während der Nietkopfbildung mittels Rollen od. dgl. zusammenzupressen, um eine feste, unter Vorspannung stehende Verbindung zu erreichen. By means of the method according to the invention, parts can be made from any Materials are riveted together. The process offers particular advantages in cases where the rivets are to be made of insulating material, e.g. B. at the mutual riveting of capacitor assignments. This is particularly advantageous Process for the formation of elastic riveted connections for materials made of elastic Material, e.g. B. leather or a leather-like plastic, applicable because the rivets made of an elastic insulating material have a certain elasticity. For example, leather parts for shoes, bags, etc. be riveted together. It should be useful to attach the parts to be riveted to press together at the riveting point during the formation of the rivet head by means of rollers or the like, to achieve a firm, pre-tensioned connection.
