Description
Beschreibung Schraube Die vorliegende Neuerung betrifft eine Schraube zur Befestigung in Gegenständen aus Metall oder ähnlichem machgiebigen Material. In solchen Materialien kann man nicht wie bei z. B. Holz die Schraube ohne weiteres in das Material einschrauben, sondern muss erst ein Glattloch bohren, worin danach ein Gewinde geschnitten wird, und erst dann kann man die Schraube einschrauben. Es sind also drei aufeinanderfolgende Operationen erforderlich, bevor die Schraube an ihrem Platz ist, und ausserdem hat diese gewöhnliche Befestigungsweise den Nachteil, dass das gebohrte Loch relativ lange offen ist. Dieses ist insbesondere dann unzweckmässigg wenn es sich um das Einsetzen von Befestigungsschrauben in hohle Gegenstände mit geringer Materialdicke und wassergefülltem Inneren wie z. B. die sogenannten Flachheizkörper zwecks Anbringung von Wärmemessern handelte oder wenn Luftschrauben oder Manometer auf hohlen Gegenständen mit Innendruck angebracht erden sollen.Description screw The present innovation concerns a screw for fastening in objects made of metal or similar machinable Material. In such materials one cannot as with z. B. wood the screw screw into the material without further ado, but must first drill a smooth hole, In which a thread is then cut, and only then can the screw be screwed in. So three consecutive operations are required before the screw is in place, and furthermore this usual method of fastening has the disadvantage that the drilled hole is open for a relatively long time. This is particularly then inexpedient when it comes to inserting fastening screws into hollow objects with low material thickness and water-filled interior such as B. the so-called panel radiators acted for the purpose of attaching heat gauges or if propellers or pressure gauges should be attached to hollow objects with internal pressure.
Zweck der Neuerung ist es eine Schraube anzugeben, durch die die obengenannten Nachteile vermieden werden, und zu diesem Zweck ist die Schraube gemäss der Neuerung dadurch eigentümlich, dass das Ende der Schraube als eine Kombination eines Bohrers und eines Schneidbolzens, dessen Gänge unmittelbar in das Schraubengewinde übergehen. The purpose of the innovation is to specify a screw through which the Above mentioned disadvantages can be avoided, and for this purpose the screw is according to peculiar to the innovation in that the end of the screw as a combination a drill and a cutting bolt, the threads of which go directly into the screw thread pass over.
Die Einsetzung einer solchen Schraube erfordert lediglich einen einzelnen Arbeitsgang, während dessen das vom Bohrer am Schraubenende gebildete Loch fast sofort gewindgeschnitten wird und unmittelbar danach das Schraubengewinde aufnimmt. Am Anfang des Bohrvorganges die Späne an der Aussenseite des Gegenstandes austreten können, bis das Schraubengewinde das gebohrte Loch schliesst und die letzten Späne werden in das Innere des Gegenstandes hineingedrückt. Durch Anpassung der Grösse des Abstandes zwischen der Spitze des Bohrers und dem Beginn des Schraubengewindes an die Materialdicke des Gegenstandes kann dafür gesorgt werden, dass das Schraubengewinde das Loch eben in dem Augenblick nach aussen schließt, wo die Spitze des Bohrers hindurchdringt. Bei wassergefüllten Heizkörpern ergibt sich z. B. oft in genanntem Augenblick ein ganz kleiner Wasserstrahl, der das Loch vor dessen Schliessen von Spänen reinigt. The installation of such a screw only requires a single one Operation during which the hole formed by the drill at the end of the screw is almost is immediately thread-cut and immediately thereafter takes up the screw thread. At the beginning of the drilling process, the chips emerge on the outside of the object until the screw thread closes the drilled hole and the last chips are pressed into the interior of the object. By adjusting the size the distance between the tip of the drill and the start of the screw thread to the material thickness of the object can be ensured that the screw thread the hole closes outwards just at the moment where the tip of the drill penetrates. at water-filled radiators z. B. often at the named moment a very small jet of water that hits the hole in front of it Closing of chips cleans.
Die Neuerung wird im Folgenden näher beschrieben unter Verweis auf die Zeichnung. The innovation is described in more detail below with reference to the drawing.
Figur 1 zeigt perspektivisch eine Ausführungsform für eine Schraube
gemäss der Neuerung und Figur 2 zeigt in ähnlicher Weise eine zweite Aus-
In der in Figur 1 gezeigten Ausführungsform hat die Schraube einen Gewindeteil 10, dessen Vorderende als ein Flachbohrer 11 ausgebildet ist, der parallel mit einer Diametralebene der Schraube Seitenflächen 12 und Kantenflächen 13 hat. In the embodiment shown in Figure 1, the screw has one Threaded part 10, the front end of which is designed as a flat drill 11, which is parallel has side surfaces 12 and edge surfaces 13 with a diametrical plane of the screw.
Von den Kantenflächen 13 ausgehende Schrägflächen stossen an der Spitze des Bohrers zusammen und bilden eine Schneide 14.Inclined surfaces emanating from the edge surfaces 13 abut at the tip of the drill together and form a cutting edge 14.
An den Kantenflächen 13 sind gehärtete Gänge mit der gleichen Steigung wie das Gewinde am Teil 10 vorhanden. Eventuell können die Kantenflächen in der Nähe des Bohrers den gleichen Durchmesser wie der Kern des Gewindes haben und zur Bildung eines Glattloches eine Fortsetzung des Bohrers bilden.On the edge surfaces 13 there are hardened threads with the same slope like the thread on part 10. The edge surfaces in the Near the drill bit the same diameter as the core of the thread and used to Forming a smooth hole to form a continuation of the drill.
Der Gewindeteil hat in der in Figur 1 gezeigten Ausführungsform einen festen Dichtungsflansch 159 sodass wenn die Schraube in einem nicht gezeigten Gegenstand an ihren Platz gebracht ist, mittels einer nicht gezeigten Packung zwischen dem Dichtungsflansch und dem Gegenstand gedichtet werden kann. In the embodiment shown in FIG. 1, the threaded part has a fixed sealing flange 159 so that when the screw is in an object not shown is brought into place by means of a pack, not shown, between the Sealing flange and the object can be sealed.
Die Schraube kann mittels eines Schraubenziehers, der in einem Schlitz 16 im anderen Ende der Schraube eingesetzt wird, oder durch Verwendung eines handgetriebenen Werkzeuges in Zusammenwirken mit dem Dichtungsflansch, dessen Aussenkante zweckmässig als ein Sechseck ausgebildet ist, in den Gegenstand hineingedreht werden. The screw can be screwed into a slot using a screwdriver 16 is inserted into the other end of the screw, or by using a hand-operated Tool in cooperation with the sealing flange, the outer edge of which is appropriate is designed as a hexagon, can be screwed into the object.
An dem nach dem Einsetzen in den Gegenstand freien Ende der Schraube kann ein Montierungsteil 17 für eine nicht gezeigte Armatur, z. B. einen Wärmemesser für den Fall, dass der Gegenstand ein Heizkörper ist, angebracht sein. Sofern die Armatur eine Entlüftungsschraube oder ein Druckmesser oder ein anderes Instrument ist, das mit dem Inneren des Gegenstandes verbunden sein soll, kann die Schraube ein durchgehendes Loch 18 aufweisen. At the end of the screw that is free after it has been inserted into the object can be a mounting part 17 for a fitting, not shown, for. B. a heat meter in the event that the object is a radiator, be attached. Unless the Fitting a vent screw or a pressure gauge or a other Is the instrument that is to be connected to the interior of the object, the Screw have a through hole 18.
In Figur 2 ist der Gewindeteil 10 der Schraube als ein Rohr ausgebildet und das freie Ende des Rohres ist als ein Ringbohrer mit Schneiden 19 ausgestaltet. Der Gewindeteil trägt eine Gegenmutter 20 und eine weitere Mutter 21, die mit dem Gewindeteil fest verbunden sein und zum Einschrauben der Schraube dienen kann. Am freien Ende der Schraube ist ein Vierkant 22 zum Einschrauben der Schraube oder zur Befestigung einer Armatur vorhanden. Die Ausbildung und Anwendung solcher Teile hängen von derjenigen Armatur ab, die auf den Gegenstand montiert werden soll, und können nach Bedarf verändert werden. In Figure 2, the threaded part 10 of the screw is designed as a tube and the free end of the tube is designed as a ring drill with cutting edges 19. The threaded part carries a lock nut 20 and another nut 21, which with the Threaded part can be firmly connected and can be used to screw in the screw. At the free end of the screw is a square 22 for screwing in the screw or available for attaching a fitting. The training and application of such parts depend on the valve that is to be mounted on the object, and can be changed as required.
