Vorrichtung zum Verschweißen von thermoplastischen KunststoffprofilenDevice for welding thermoplastic plastic profiles
Die Erfindung bezieht sich auf eine Vorrichtung zum Verschweißen von thermoplastischen Kunststoffprofilen, mit Spannschlitten zum Aneinanderpressen der Enden der in die Spannschlitten eingespannten Profile und mit einem Schweißspiegel zum Erhitzen der zu verbindenden Profilenden durch Berührung mit dem Schweißspiegel. The invention relates to a device for welding thermoplastic plastic profiles, with clamping slide for Pressing together the ends of the clamped in the clamping slide Profiles and with a welding mirror for heating the profile ends to be connected by touching the welding mirror.
Vorrichtungen dieser Art sind hinlänglich bekannt. Sie bestehen aus einem Grundrahmen, auf dem mehrere Spannschlitten zum Einspannen der Profile, etwa zur Herstellung von Fensteroder Türrahmen verschieblich montiert sind. Die Spannschlitten haben im allgemeinen einen Winkelabstand von 90° voneinander, so daß man zwei Profile geradlinig, rechtwinklig oder auch drei oder vier Profile t- oder kreuzförmig miteinander verschweißen kann. Auf dem Grundrahmen ist beweglich ein sogenannter Schweißspieg~l gelagert, der zwischen die in die Spannschlitten eingespannten Profile eingeführt werden kann, so daß man die Enden der Profile gegen den Schweißspiegel beiderseitsDevices of this type are well known. You insist from a base frame on which several clamping slides for clamping the profiles, for example for the production of windows or Door frames are slidably mounted. The clamping slides are generally at an angular distance of 90 ° from one another, so that two profiles can be welded to one another in a straight line, at right angles or three or four profiles in a t or cross shape can. A so-called welding mirror is movably mounted on the base frame and is placed between the clamping slide clamped profiles can be introduced so that the ends of the profiles against the welding mirror on both sides

andrücken kann, um sie zu erhitzen. Alsdann werden die Profile auseinandergefahren und der Jchweißspiegel weggeschwenkt, um anschließend die erhitzten Profilenden mit den Spannschlitten zur Verschweißung aneinanderzupressen. Der erhitzte und erweichte Kunststoff beider Profilenden verbindet sich dabe: und bildet einen über die Kontur der Profilstäbe vorspringenden Schweißwulst.can press down to heat it. Then the profiles moved apart and swiveled the welding mirror away, in order to then press the heated profile ends together with the clamping slide for welding. The heated and softened plastic on both profile ends is connected: and forms a welding bead protruding over the contour of the profile rods.

Gründen anschließend entfernt werden. Nach der klassischen Methode geschieht dies durch arbeitsaufwendige Stemm-, Schleirund Polierarbeit.Reasons are subsequently removed. According to the classic method, this is done using labor-intensive caulking and grinding rounds Polishing work.
Daneben ist aber auch schon ein Verfahren bekannt geworden, das die Bildung einer Schweißwulst von vorneherein verhindert. Hierfür bedient man sich eines Heizkörpers der der Außenkontur der zu verschweißenden Jinden der Profile entsprechend geformte Heizf orinausnehmungen aufweist.In addition, a process has also become known which prevents the formation of a weld bead from the start. For this one uses a radiator of the outer contour the Jinden of the profiles to be welded has correspondingly shaped Heizf orinausnehmungen.
Der Erfindung liegt nun die Aufgabe zugrunde, zwar nicht der Bildung eines Schweißwulstes entgegen zu wirken, jedoch Vorsorge dafür zu treffen, daß derselbe unmittelbar nach dem Schweiß-Vorgang ohne manuelle Bearbeitung der Prol'ilenden entfernt werden kann.The invention is based on the object of not counteracting the formation of a weld bead, but of taking precaution to ensure that it is removed immediately after the welding process without manual processing of the prol'il ends can be.

genannten Art erfindungsgemäß dadurch gelöst, daß an den Spannschlitten Zusatzschlitten angeordnet sind, die separat gegenläufig verfahrbar gelagert sind und deren jeweils gegeneinander gerichtete freie Enden mit Messern bestückt sind, die mit ihren der Umfangekontur der Profile angepaßten Schneiden plan auf den Profilflächen geführt sind und nach beendetem Schweißvorgang aufeinandertreffen. Durch diese erfindungsgemäße Maßnahme wird der Schweißwulst infolge der aufeinandertreffenden Messerschneiden unmittelbar nach Beendigung des Schweißvorganges abge-mentioned type according to the invention solved in that on the clamping slide Additional slides are arranged, which are separately movable in opposite directions and each of them against each other directed free ends are equipped with knives that are flat with their cutting edges adapted to the circumferential contour of the profiles the profile surfaces are guided and meet after the welding process. This measure according to the invention is the weld bead as a result of the knife edges meeting each other immediately after the end of the welding process

Die gegeneinanderlaufende Bewegung der Zusatzschlitten kann durch die Bewegung begrenzende Anschläge bestimmt werden. Auch kann nach einem weiteren Merkmal der Erfindung vorgesehen sein, daß der Anschlag (oder die Anschläge) beidseitig keilförmige Auflaufschrägen für die Zusatzschlitten besitzt. Hierdurch wirken die Messer noch konturenbestimmend und vermögen Unterschiede der Kunststoffprofile auszugleichen.The counter-rotating movement of the additional slide can be determined by the movement-limiting stops. Also can According to a further feature of the invention it can be provided that the stop (or the stops) are wedge-shaped on both sides Has run-on slopes for the additional slide. As a result, the knives still have a contour-determining effect and are capable of differences to compensate for the plastic profiles.
Der Erfindung zufolge können fernerhin ebensoviel Messerschneiden wie -frofiloberflächen vorgesehen sein, wobei es im Ermessen des Fachmannes liegt, profilierte Messer z. B. Winkelmesser oder mehrere Zusatzschlitten einzusetzen.According to the invention, there can also be as many knife edges as -frofiled surfaces, with discretion of the expert lies, profiled knife z. B. to use protractors or several additional slides.

Schließlich können die Messer noch erfindungsgemäß wegklappbar an den Zusatzschlitten gelagert sein, um die Bearbeitung schwieriger Profilformen zu erleichtern.Finally, according to the invention, the knives can still be folded away be mounted on the additional slide to facilitate the processing of difficult profile shapes.
