Description

Die Erfindung betrifft einen Schraubstopfen zum Verschließen einer Öffnung in vorzugsweise mit Pulver zu beschichtenden Teilen, beispielsweise Heizkörpern, mit einem in die mit einem Innengewinde versehene Öffnung einzusetzenden, mit Außengewinde versehenen, büchsenförmigen Verschlußteil und einem hieran angeformten, mit Schlüsselflächen für ein Werkzeug versehenen, scheibenförmigen Abschlußteil. Gattungsgemäße Schraubstopfen sind bekannt durch die US-A-1 032 701 und die US-A-2 101 030The invention relates to a screw plug for closing an opening in preferably parts to be coated with powder, for example radiators, with an opening to be inserted into the internally threaded opening, externally threaded, sleeve-shaped closure part and one molded onto it, with key surfaces for a tool provided, disc-shaped end part. Generic screw plugs are known from US-A-1 032 701 and US-A-2 101 030

Schraubstopfen der voranstehend beschriebenen Art werden verwendet, um die Öffnungen von Teilen zu verschließen, die mit einer Beschichtung, insbesondere einer Pulverbeschichtung versehen werden sollen. Bevorzugt werden derartige Schraubstopfen verwendet, um Heizkörper zu verschließen, wenn diese einer Dichtigkeitsprüfung unterzogen, anschließend gereinigt, grundiert und abschließend pulverbeschichtet werden. Die Schraubstopfen dienen hierbei einerseits dem druckdichten Verschließen des Heizkörpers und andererseits der Abdeckung der Öffnung, damit deren Innengewinde nicht mit Beschichtungsmaterial versehen wird, das ein späteres Einschrauben eines Anbauteiles behindert.Screw plugs of the type described above are used to close the openings of parts covered with a coating, in particular to be provided with a powder coating. To be favoured such screw plugs are used to close radiators when they are subjected to a leak test, then cleaned and primed and finally powder coated. The screw plugs serve on the one hand the pressure-tight sealing of the radiator and on the other hand, the cover of the opening so that its internal thread is not included Coating material is provided, which a later screwing in Attachment hindered.

Schraubstopfen der eingangs beschriebenen Art sind bekannt. Sie sind unmittelbar im Anschluß an das Außengewinde mit einer ringförmigen Dichtfläche versehen, durch deren Anlage an der Stirnfläche des mit der Öffnung versehenen Teiles die Abdichtung erfolgt.Screw plugs of the type described in the introduction are known. You are immediate following the external thread with an annular sealing surface provided by their abutment on the end face of the one provided with the opening Part of the sealing is done.

Diese bekannten Verschlußstopfen haben verschiedene Nachteile. Zum einen können Undichtigkeiten entstehen, wenn die sich unmittelbar an das Gewindeende anschließende, radial verlaufende Dichtfläche des Verschlußstopfens durch Blockaden im Gewinde nicht zur Anlage an der Stirnfläche des abzudichtenden Teiles gelangt. Andererseits ergeben sich zwischen dieser Stirnfläche und der etwa rechtwinklig abstehenden zylindrischen Mantelfläche des Stopfen-Abschlußteiles bei einer Beschichtung Konzentrationen von Beschichtungsmaterial, die nach dem Entfernen des Schraubstopfens entweder zu einer ringförmigen Anhäufung von Beschichtungsmaterial führen oder zu einer Beschädigung der Beschichtung, wenn beim Ausdrehen des Schraubstopfens dieses ringförmig angehäufte Beschichtungsmaterial abreißt.These known plugs have several disadvantages. On the one hand Leaks can occur if they are directly at the thread end subsequent, radially running sealing surface of the sealing plug due to blockages in the thread, it does not come into contact with the face of the seal Part arrives. On the other hand, there are between this end face and the cylindrical surface of the Plug end part in a coating concentrations of coating material, after removing the screw plug either into one ring-shaped accumulation of coating material or damage the coating if when unscrewing the screw plug this coating material piled up in a ring is torn off.

Der Erfindung liegt die Aufgabe zugrunde, einen Schraubstopfen der eingangs beschriebenen Art zu entwickeln, der unter Vermeidung der voranstehenden Nachteile stets zu einer zuverlässigen Abdichtung führt und Beschädigungen des Beschichtungsmaterials beim Entfernen des Schraubstopfens vermeidet.The invention has for its object to develop a screw plug of the type described, which always leads to a reliable seal while avoiding the above disadvantages and avoids damage to the coating material when removing the screw plug.

Die Lösung dieser Aufgabenstellung durch die Erfindung ist dadurch gekennzeichnet, daß zwischen dem Außengewinde des Verschlußteils und dem dieses in radialer Richtung überragenden Abschlußteil ein Gewindefreistich mit konisch verlaufender Schulter und ein im Querschnitt V-förmiger Einstich ausgebildet sind.The solution to this problem by the invention is characterized in that a thread undercut with a conical shoulder and a cross-sectionally V-shaped recess are formed between the external thread of the closure part and the end part projecting beyond it in the radial direction.

Durch den sich an das Außengewinde des Schraubstopfens unmittelbar anschließenden Gewindefreistich mit konisch verlaufender Schulter ergibt sich ein druckdichtes Anziehen des Schraubstopfens auch dann, wenn das Schraubgewinde verunreinigt sein sollte. Diese Verunreinigungen werden über den Gewindefreistich ausgeworfen; die konisch verlaufende Schulter liegt in jedem Fall zuverlässig abdichtend an der Stirnfläche des abzudichtenden Teiles an. Durch den im Querschnitt V-förmigen Einstich wird verhindert, daß sich beim Beschichten Beschichtungsmaterial zwischen der Stirnfläche des zu beschichtenden Teiles und dem Abschlußteil des Schraubstopfens ansammelt. Das radial hervorstehende Abschlußteils des Schraubstopfens verhindert eine Anhäufung von Beschichtungsmaterial um die Schrauböffnung herum ; sich dennoch ansammelndes Beschichtungsmaterial gelangt in den V-förmigen Einstich und wird beim Herausdrehen des Schraubstopfens mit diesem entfernt, ohne daß es zu Beschädigungen der Beschichtung kommt. Because of the directly following on the external thread of the screw plug Thread undercut with a tapered shoulder results a pressure-tight tightening of the screw plug even if that Screw thread should be contaminated. These contaminants are over the thread undercut ejected; the conical shoulder lies in in any case reliably sealing on the end face of the part to be sealed on. The V-shaped recess in cross section prevents when coating coating material between the end face of the to be coated Part and the end of the screw plug accumulates. The radially protruding end part of the screw plug prevents one Accumulation of coating material around the screw hole; yourself coating material still accumulating gets into the V-shaped Puncture and when unscrewing the screw plug with this removed without damaging the coating.

Durch die erfindungsgemäße Weiterbildung des Verschlußstopfens werden somit sowohl Dichtigkeitsprobleme als auch Beschädigungen der Beschichtung vermieden.Through the development of the sealing plug according to the invention thus both tightness problems and damage to the coating avoided.

Bei einer bevorzugten Ausführungsform der Erfindung verläuft die Schulter des Gewindefreistiches unter einem Winkel von 40°. Der Öffnungswinkel des V-förmigen Einstiche beträgt vorzugsweise 60°.In a preferred embodiment of the invention, the shoulder of the Thread undercut at an angle of 40 °. The opening angle of the V-shaped Punctures are preferably 60 °.

Um eine Art Sollbruchstelle bei dem sich um den Verschlußstopfen ansammelnden Beschichtungsmaterial zu schaffen, wird gemäß einem weiteren Merkmal der Erfindung vorgeschlagen, zwischen dem Gewindefreistich und dem Einstich eine schmale zylindrische Mantelfläche auszubilden, deren axiale Länge vorzugsweise zwischen 0,5 und 1,0 mm liegt. Im Bereich dieser Mantelfläche wird sich ggf. im Einstich des Schraubstopfens ansammelndes Beschichtungsmaterial von der eigentlichen Beschichtung getrennt.To a kind of predetermined breaking point at which accumulates around the plug Creating coating material is according to another Feature of the invention proposed between the thread undercut and the puncture to form a narrow cylindrical surface, the axial Length is preferably between 0.5 and 1.0 mm. In the area of this lateral surface coating material that may accumulate in the recess of the screw plug separated from the actual coating.

Bei einer bevorzugten Ausführungsform der Erfindung sind die Schlüsselflächen des Abdeckteils als Innenflächen ausgebildet. Hierdurch ergeben sich Schraubstopfen mit niedriger Bauhöhe. Die Schlüsselflächen sind so ausgebildet, daß keine Medien festgehalten werden, die durch späteres Abtropfen Schäden verursachen können. Der Schraubstopfen wird schließlich vorzugsweise einstückig aus Kunststoff hergestellt.In a preferred embodiment of the invention, the key surfaces of the cover part formed as inner surfaces. This results in Screw plugs with a low overall height. The key areas are like this trained that no media are captured by later Dripping can cause damage. The screw plug will eventually preferably made in one piece from plastic.

Der auf der Zeichnung anhand eines Ausführungsbeispiels dargestellte, vorzugsweise aus Kunststoff hergestellte Schraubstopfen dient zum Verschließen einer Öffnung in einem vorzugsweise mit Pulver zu beschichtenden Teil, beispielsweise einem Heizkörper oder einem Heizkörperbauteil. Der Schraubstopfen umfaßt ein büchsenförmiges Verschlußteil 1, das mit einem Außengewinde 2 versehen ist, und ein scheibenförmiges Abschlußteil 3, das mit Schlüsselflächen 4 für ein Werkzeug versehen ist. Verschlußteil 1 und Abschlußteil 3 sind einstückig, beispielsweise im Spritzgießverfahren hergestellt.The one shown in the drawing using an exemplary embodiment, preferably Screw plugs made of plastic are used for closing an opening in a part to be preferably coated with powder, for example a radiator or a radiator component. The screw plug comprises a sleeve-shaped closure part 1, which has an external thread 2 is provided, and a disc-shaped end part 3, with Key surfaces 4 is provided for a tool. Closure part 1 and end part 3 are made in one piece, for example by injection molding.

Der Schraubstopfen wird beispielsweise zur Durchführung einer Dichtigkeitsprüfung in eine Öffnung eines zu beschichtenden Teiles T eingeschraubt, beispielsweise eines Heizkörpers. Ein Abschnitt dieses Teiles T ist im Schnitt in Fig. 4 dargestellt. Die zu verschließende Öffnung ist mit einem Innengewinde I versehen.The screw plug is used, for example, to carry out a leak test screwed into an opening of a part T to be coated, for example a radiator. A section of this part T is in section shown in Fig. 4. The opening to be closed is with an internal thread I provided.

Um auch dann, wenn sich in diesem Innengewinde I Schmutzpartikel oder andere Verunreinigungen befinden, einen dichten Abschluß mit Hilfe des Schraubstopfens zu erzielen, ist zwischen dessen Außengewinde 2 und dem dieses in radialer Richtung überragenden Abschlußteil 3 ein Gewindefreistich 5 mit einer konisch verlaufenden Schulter 6 ausgebildet. Hierdurch wird erreicht, daß sich gemäß den Fig. 4 und 5 die Schulter 6 dichtend an den Rand der zu verschließenden Öffnung im Teil T anlegt, auch wenn das Gewinde nicht frei von Verunreinigungen ist. Eine derartige dichtende Anlage der konischen Schulter 6 am zu beschichtenden Teil T ist in den Fig. 4 und 5 dargestellt.To even if there are dirt particles or other in this internal thread Impurities, a tight seal with the help of To achieve screw plug is between its external thread 2 and this in the radial direction projecting end part 3 a thread undercut 5th formed with a tapered shoulder 6. This ensures that according to FIGS. 4 and 5, the shoulder 6 sealing against the edge of the closing opening in part T, even if the thread is not free of impurities. Such a sealing system of the conical Shoulder 6 on the part T to be coated is shown in FIGS. 4 and 5.

Diese Darstellungen zeigen auch, daß sich an die konisch verlaufende Schulter 6 des Gewindefreistiches 5 in Richtung auf das Abschlußteil 3 ein im Querschnitt V-förmiger Einstich 7 anschließt, der verhindert, daß sich bei einer Beschichtung des Teiles T Beschichtungsmaterial in einer solchen Menge zwischen dem Abschlußteil 3 des Schraubstopfens und der Stirnfläche des Teiles T ansammelt, daß sich ein ringförmiger Grat ergibt, wenn der Schraubstopfen nach der Beschichtung entfernt wird. Das bei der Beschichtung zwischen Abschlußteil 3 und der Stirnfläche des zu beschichtenden Teiles T gelangende Beschichtungsmaterial wird im wesentlichen durch den V-förmigen Einstich aufgenommen und auf diese Weise beim Herausdrehen des Schraubstopfens entfernt.These representations also show that the tapered shoulder 6 of the thread undercut 5 in the direction of the end part 3 in cross section V-shaped recess 7 connects, which prevents that during a coating of the part T coating material in such an amount between the end part 3 of the screw plug and the end face of the Part T accumulates that there is an annular ridge when the Screw plug is removed after coating. That with the coating between the end part 3 and the end face of the part to be coated T coating material is essentially by the V-shaped Puncture recorded and in this way when unscrewing the Screw plug removed.

Um hierbei eine Beschädigung des aufgetragenen Beschichtungsmaterials im Umkreis der durch den Schraubstopfen verschlossenen Öffnung zu vermeiden, ist zwischen der konischen Schulter 6 des Gewindefreistiches 5 und dem V-förmigen Einstich 7 eine schmale zylindrische Mantelfläche 8 ausgebildet, durch die eine Art Sollbruchstelle geschaffen wird, an der sich beim Herausschrauben des Schraubstopfens das im Einstich 7 befindliche Beschichtungsmaterial von demjenigen Beschichtungsmaterial trennt, das auf die Stirnfläche des Teiles T aufgetragen worden ist.To prevent damage to the applied coating material in the To avoid the circumference of the opening closed by the screw plug, is between the conical shoulder 6 of the thread undercut 5 and the V-shaped Recess 7 formed a narrow cylindrical surface 8, through which a kind of predetermined breaking point is created, at which when unscrewing of the screw plug the coating material located in the recess 7 separates from the coating material on the face of part T has been applied.

Durch den voranstehend beschriebenen und in der Zeichnung dargestellten Schraubstopfen wird somit nicht nur ein druckdichter Verschluß der im zu beschichtenden Teil T ausgebildeten Öffnung erreicht, sondern auch Beschädigungen des Beschichtungsmaterials im Umkreis dieser Öffnung vermieden, wenn der Schraubstopfen nach der Beschichtung entfernt wird.By the above described and shown in the drawing Screw plug is therefore not only a pressure-tight closure of the to be coated Part T trained opening reached, but also damage avoid the coating material around this opening, if the screw plug is removed after coating.
