Maschine zum Schweissen von auf Gehrung geschnittenen KunststoffprofilenMachine for welding miter cuts Plastic profiles

Die Neuerung bezieht sich auf eine Maschine zum Schweissen von auf Gehrung geschnittenen Kunststoffprofilen, vorzugsweise von Fenster- oder Türprofilen, mit in einem Winkelabstand von 9o angeordneten, in ihrer Längsachse verschiebbaren Schlitten.The innovation relates to a machine for welding mitered plastic profiles, preferably of window or door profiles, arranged at an angular distance of 9o, displaceable in their longitudinal axis Sleds.

Bisher sind diese Verschwelssungen nicht automatisch vorgenommen worden. Bei den benutzten Maschinen musste die Aufspannung der Profile auf die Schlitten von Hand vorgenommen werden. Weiterhin wurden der Aufheizdruck und der Schweissdruck von Hand aus aufgebracht, so dass konstante Drücke nicht gewährleistet waren.So far, these weldings have not been carried out automatically been. With the machines used, the profiles had to be clamped onto the slides by hand will. Furthermore, the heating pressure and the welding pressure were applied by hand, so that constant Pressures were not guaranteed.

Der Neuerung liegt die Aufgabe zugrunde, eine Maschine zum Verschweissen von auf Gehrung geschnittenen Kunststoffprofilen zu entwickeln, durch die die Gehrungen exakt ausgerichtet und der Aufheizdruck sowie der Verschweissdruck für eine bestimmte Profilart konstant gehalten werden. Weiterhin soll der Druck für jeden Profilquerschnitt einstellbar sein.The innovation is based on the task of creating a machine for welding mitered plastic profiles to develop, through which the mitres are precisely aligned and the heating pressure and the welding pressure for a certain profile type can be kept constant. Furthermore, the pressure should be adjustable for each profile cross-section.

Diese Aufgabe wird nach der Neuerung durch eine Maschine der oben genannten Art dadurch gelöst, dass die in ihrer Längsachse verschiebbaren Schlitten zum Aufspannen der zu verschwelssenden Profilteile über ein Getriebemittel gekoppelt sind. DasAccording to the innovation, this object is achieved by a machine of the above-mentioned type in that the in its longitudinal axis sliding carriage for clamping the welded ones Profile parts are coupled via a transmission means.

Getriebemittel kann als Kurvenscheibe ausgebildet sein, an der die einzelnen Schlitten über Laschen angelenkt sind. Andieser Kurvenscheibe greift als Antrieb ein Druckluftzylinder an, der mit verschiedenen Drücken beaufschlagt werden kann. Für das Aufheizen der Gehrungsflächen wird ein geringerer Druck benötigt als beim eigentlichen Schweissvorgang. Zum Aufheizen der Gehrungsflächen wird in an sich bekannter Weise ein Heizspiegel, eine Heizplatte, zwischen die Gehrungsflächen gefahren. Mit einem bestimmten Druck weiden dann die Gehrungsfächen auf den Heizspielgel gepresst. Nach dem Aufheizvorgang werden die Heizspiegel aus dem Bereich der Gehrungsflächen gefahren, die dann mit einem höheren Druck aufeinandergepresst werden.Transmission means can be designed as a cam, to which the individual carriages are articulated via brackets. A compressed air cylinder to which various pressures are applied acts as a drive on this cam disk can. Less pressure is required to heat up the miter surfaces than during the actual welding process. To the The miter surfaces are heated in a manner known per se using a heating mirror, a heating plate, between the miter surfaces drove. With a certain pressure, the miter surfaces graze pressed onto the heating gel. After the heating process, the heating mirrors are moved out of the area of the miter surfaces, which are then pressed together with a higher pressure will.

Zur Steuerung der verschiedenen Anpressdrucke sind dem genannten Druckluftzylinder zwei Druckluftregelventile zugeordnet.To control the various contact pressures are the named air cylinder two air pressure control valves assigned.

Bei einer vorteilhaften Ausführungsform der Neuerung ist jedem Schlitten mindestens eine auf einem Querschlitten stufenlos verstellbare Spannvorrichtung zugeordnet, deren Spannwerkzeug unter einem Winkel von 4-5 gegenüber der horizontalen Aufspannfläche des Schlittens geneigt ist. Um neben der Winkel schieis sung auch eine T-Schweissung und eine Kreuzschweissung vornehmen zu können, ist es vorteilhaft, die Maschine mit vier Schlitten auszurüsten. Für die Winkelschweissung werden zwei Schlitten, für die T-Schweissung M drei Schlitten und für die Kreuzschweissung vier Schlitten benötigt, die mit der genannten Kurvenscheibe gekoppelt sind. Die bei einer Schweissung nicht benötigten Schlitten werden von der Kurvenscheibe losgekoppelt.In an advantageous embodiment of the innovation, each slide is at least one on a cross slide continuously adjustable clamping device assigned whose clamping tool at an angle of 4-5 compared to the horizontal clamping surface of the slide is inclined. In addition to the angle joint, there is also a T-joint and to be able to cross-weld, it is advantageous to to equip the machine with four slides. Two slides are used for angle welding and M. For T-welding three slides and four slides for cross welding required, which are coupled to the named cam. The slides that are not required for welding are decoupled from the cam.

Nach dem Aufheizen werden die Schlitten so weit zurückgefahren, dass der Heizspiegel aus dem Bereich der Gehrungsflächen entfernt werden kann. Mit erhöhtem Anpressdruck erfolgt hierauf die Verschweissung. Zur Entnahme der miteinander verschweissten Teile werden d: e Spannwerkzeuge gelöst. In dem Ausfuhrungsbeispiel weist der Spannzylinder 18 eine Neigung von 45° auf und ist über ein Flacheisen 27 mit dem Querschlitten 14 verbunden.For safety reasons there is a stop bar on the machine table 25 movably mounted, which can be moved between the mitres of the profiles to be welded. During the heating of the profile miter surfaces, the stop bar 25 is moved out of the area of the miter surfaces. In the jl Space between the viewing surfaces to be welded Then the heating mirror 26 is introduced, onto which the miter surfaces are pressed with a certain pressure. To this For this purpose, the carriages are moved in the direction of the heating mirror. After heating up, the sledges get that far pulled back that the heating mirror is out of the range of the Miter surfaces can be removed. The welding then takes place with increased contact pressure. For removal of the parts welded together become d: e clamping tools solved. In the exemplary embodiment, the clamping cylinder 18 has an inclination of 45 ° and is via a flat iron 27 connected to the cross slide 14.
