Description
Die Erfindung betrifft eine Baugruppe mit mindestes zwei Profilen aus Kunststoff, die endseitig durch eine Schweißnaht stoffschlüssig miteinander verbunden sind, wobei zumindest eines der Profile als Hohlprofil mit mindestens einer Hohlkammer ausgebildet ist.The The invention relates to an assembly with at least two profiles Plastic, the end connected by a weld material fit together are, wherein at least one of the profiles as a hollow profile with at least a hollow chamber is formed.
Bei der Verschweißung von Kunststoff-Hohlprofilen – insbesondere wenn es sich um dünnwandige, harte Hohlprofile handelt – besteht das Problem, dass sich die Wandungen der Profile im Bereich der Schweißnaht aufgrund der lokal hohen Temperaturbelastung und/oder der Fügekräfte wellen können. Aufgrund der funktionsbedingten Geometrie sind die Innenflächen der Profilwandungen nämlich nicht durch ein Schweißwerkzeug abstützbar. Beim Fügevorgang kommt es daher häufig zu Überlappungen, Versatz sowie erhöhten Schweißgraten. Es ist dann kein ansprechendes Erscheinungsbild des fertig verschweißten Produktes mehr gegeben. Unter Umständen kann dies auch die Schweißnahtfestigkeit herabsetzen.at the welding of plastic hollow sections - in particular if it is thin-walled, Hard hollow sections is - consists the problem is that the walls of the profiles in the area of the weld due to the locally high temperature load and / or the joining forces waves can. by virtue of the functional geometry are the inner surfaces of the Profile walls namely not by a welding tool supportable. During the joining process that's why it often happens to overlaps, offset as well as elevated Schweißgraten. It is then no appealing appearance of the finished welded product more given. In certain circumstances This can also reduce the weld strength.
Im Stand der Technik wird als Gegenmaßnahme ein Öffnen der Hohlkammern im Fügebereich vorgenommen, um diesen abstützen zu können. Dies hat jedoch zusätzliche Arbeitsgänge und damit höhere Kosten zur Folge.in the In the prior art, as a countermeasure, an opening of the hollow chambers in the joint area is made, to support this to be able to. However, this has additional operations and thus higher Costs result.
Vor diesem Hintergrund besteht die der Erfindung zu Grunde liegende Aufgabe darin, eine Baugruppe mit den eingangs beschriebenen Merkmalen anzugeben, welche sich durch eine optisch einwandfreie Schweißnaht auszeichnet und gleichzeitig kostengünstig herstellbar ist.In front This background is the basis of the invention The task is to specify an assembly with the features described above, which is characterized by a visually perfect weld and at the same time cost-effective can be produced.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass in den der Schweißnaht zugewandten Endbereich der Hohlkammer zumindest ein Einsteckteil eingeschoben ist, das zur Stabilisierung dieses Endbereiches während des Herstellens der Schweißnaht dient. Erfindungsgemäß gewährleistet das Einsteckteil, welches bei entsprechender Materialwahl mitverschweißt werden kann, während des Fügevorganges die Formstabilität der dünnen Hohlprofilwand, so dass eine optisch einwandfreie Verschweißung sichergestellt ist.According to the invention Task solved by that in the weld facing end portion of the hollow chamber at least one insertion part which is used to stabilize this end area during the Making the weld serves. Guaranteed according to the invention the plug-in part, which are mitverschweißt with appropriate choice of material can, while of the joining process the dimensional stability the thin one Hollow profile wall, so that ensures a visually perfect welding is.
Vorzugsweise ist das Einsteckteil gegen ein ungewolltes axiales Verschieben entlang der Profillängsrichtung, insbesondere während des Schweißvorganges, gesichert. Dies kann beispielsweise durch ein Verkleben oder Verrasten mit der Innenwandung des Hohlprofils erfolgen. Alternativ kann auch eine Presspassung bzw. eine entsprechend gewählte Toleranz zwischen Einsteckteil und Hohlprofil sowie die Anformung eines Bundes vorgesehen sein. Gemäß einer Ausführungsform der Erfindung schließt das Einsteckteil im eingeschobenen Zustand plan mit der zu verschweißenden Fläche des Hohlprofils ab. Alternativ kann das Einsteckteil auch im Bereich des Schweißüberstandes gegenüber dem Rand des Hohlprofils etwas zurückstehen, oder aber auch zwecks Bildung eines schmalen Bundes etwas überstehen. Insbesondere in diesem Fall wird das Einsteckteil während des Schweißvorganges kontrolliert verschoben.Preferably is the plug against unintentional axial displacement along the profile longitudinal direction, especially during the welding process, secured. This can be done, for example, by gluing or latching done with the inner wall of the hollow profile. Alternatively, too a press fit or a correspondingly selected tolerance between male part and hollow profile and the Anformung a federal be provided. According to one embodiment the invention concludes the male in the inserted state plan with the surface to be welded From hollow profiles. Alternatively, the plug in the area of sweat supernatant across from the back of the hollow profile something stand behind, or for the purpose To survive the formation of a narrow covenant. In particular in In this case, the male part becomes during the welding process controlled shifted.
Der Querschnitt der Hohlkammer kann durch das Einsteckteil im Wesentlichen vollständig ausgefüllt sein. Alternativ hierzu ist es jedoch auch möglich, dass das Einsteckteil den Querschnitt der Hohlkammer lediglich bereichsweise ausfüllt. In diesem Fall ist zumindest im Bereich der Vorderseite der Baugruppe ein vollflächiges Anliegen des Einsteckteils an der Innenwandung des Hohlprofils gegeben, so dass die gewünschte hervorragende Optik der Schweißnahtvorderseite sichergestellt ist.Of the Cross section of the hollow chamber can be substantially through the male part Completely filled out be. Alternatively, however, it is also possible that the plug only partially fills the cross section of the hollow chamber. In In this case, at least in the area of the front side of the module full-surface Concerns of the male part on the inner wall of the hollow profile given so that the desired excellent appearance of the weld front is ensured.
Vorzugsweise sind die der Schweißnaht zugewandten Enden der Profile und das Einsteckteil mit einem Winkel von ca. 45° zur Profilquerschnittsebene abgeschrägt ausgebildet, so dass die Profile im verschweißten Zustand einen im Wesentlichen rechten Winkel bilden. So kann beispielsweise die Baugruppe aus insgesamt 4 Profilen aufgebaut sein und im verschweißten Zustand einen geschlossenen Rahmen bilden. Im Rahmen der Erfindung liegt es aber auch, dass der Verschweißungswinkel ca. 25° bis ca. 180° beträgt.Preferably are those of the weld facing ends of the profiles and the male part with an angle from about 45 ° to Bevelled cross section plane formed so that the profiles in the welded state a substantially form right angle. For example, the assembly may be off a total of 4 profiles to be constructed and in the welded state form a closed frame. Within the scope of the invention but also that the welding angle is approx. 25 ° to approx. 180 °.
Die Wandstärke der Hohlprofile kann weniger als 2 mm, insbesondere weniger als 1 mm, bzw. weniger als 0,5 mm, betragen. Im Rahmen der Erfindung liegt es auch, dass die Wandstärke lediglich bzw. zumindest im Bereich der Frontseite des Hohlprofils aus konstruktiven Gründen dünn ausgebildet ist und dort weniger als 2 mm bzw. weniger als 1 mm/weniger als 0,5 mm beträgt.The Wall thickness the hollow profiles may be less than 2 mm, in particular less than 1 mm, or less than 0.5 mm. Within the scope of the invention it is also that the wall thickness only or at least in the region of the front side of the hollow profile for constructional reasons is thin and there less than 2 mm or less than 1 mm / less than 0.5 mm.
Das Einsteckteil kann – ebenso wie das Hohlprofil – aus Kunststoff bestehen. Insbesondere kann das Einsteckteil aus demselben Material wie das Hohlprofil bestehen. Denkbar ist aber auch die Verwendung eines anderen, ebenfalls schweißbaren Materials für das Einsteckteil. Als Materialien für das Hohlprofil und/oder das Einsteckteil kommen beispielsweise Hart-PVC oder ähnliche polymere Werkstoffe in Frage. Die Verwendung von weichen Werkstoffen, insbesondere als Material für das Hohlprofil, soll hierdurch jedoch nicht ausgeschlossen sein. Im Rahmen der Erfindung liegt es auch, dass das Einsteckteil aus einem nicht verschweißbaren Material besteht. In diesem Fall wird das Einsteckteil während des Schweißvorganges ggf. in das Hohlprofil zurückgeschoben.The Plug-in part can - as well like the hollow profile - off Plastic exist. In particular, the male part of the same Material exist as the hollow profile. It is also conceivable use another, also weldable material for the Plug. As materials for the hollow profile and / or the insertion come, for example, rigid PVC or similar polymeric materials in question. The use of soft materials, especially as a material for the hollow profile, but this should not be excluded. In the context of the invention, it is also that the male part a non-weldable Material exists. In this case, the plug-in part during the welding process possibly pushed back into the hollow profile.
Die erfindungsgemäße Baugruppe eignet sich bevorzugt für die Verwendung als mit eingelegten Magnetbändern versehenen Hartrahmen für Kühltruhen oder Gefriertruhen. Denkbar sind jedoch auch Anwendungen im Hausgerätebereich allgemein sowie im Auto- und Fensterbereich. Anspruch 10 betrifft ein Kühlgerät mit einer Baugruppe nach einem der Ansprüche 1 bis 9.The assembly according to the invention is suitable It is preferred for use as a rigid frame for freezer or freezer restraints provided with inserted magnetic tapes.
