Description
Schweißgerät, insbesondere Dicknaht-Schweißgerät Welding device, especially thick seam welding device
= = Die Erfindung betrifft ein Schweißgerät, insbesondere ein Dicknaht-Schweißgerät zur Verarbeitung von thermoplastischem Kunststoff-Schweißmaterial mit einem beheizbaren Schmelzrohr und einem antreibbaren Fürderelement. = = The invention relates to a welding device, in particular a thick seam welding device for processing thermoplastic welding material with a heatable Melting tube and a drivable conveyor element.
Ein derartiges Schweißgerät geht auf den Anmelder selbst zurück. Es ist für granulatförmiges Schweißmaterial konzipiert, welches über einen Trichter dem Schmelzrohr zugeführt wird. Als antreibbares Förderelement ist eine Schnecke vorgesehen, die im Schmelzrohr angeordnet ist und mit diesem als Extruder zusammenwirkt. Das Ende des Schmelzrohres ist beheizt, so daß unter Einwirkung dieser von außen zugeführten Wärme wie auch der im Schmelzrohr selbst entstehenden Reibungswärme das Schweißmaterial plastifiziert wird.Such a welding device goes back to the applicant himself. It is for granular welding material designed which over a funnel is fed to the melting tube. As a drivable conveyor element a screw is provided, which is arranged in the melting tube and with this as an extruder cooperates. The end of the melting tube is heated, so that under the action of this externally supplied heat as well as the frictional heat generated in the melting tube itself the welding material is plasticized.
Dieses Schweißgerät hat sich in der Praxis vielfältig bewährt, jedoch gibt es einige Anwendungsfälle, bei denen es nicht zum Einsatz kommen kann. So erlaubt die Tatsache, daß das Schweißmaterial granulatförmig ist und frei im Trichter lagert, keine Handhabung des Schweißgerätes in beliebiger Stellung, also z. B. kein Schweißen über Kopf, wie es bei Rohren, Rohrböden od. dgl. erforderlich werden kann, da dabei das Schweißmaterial a-J dem Trichter herausfließen würde. Auch hat sich gezeigt, daß die Verweadung von PVC (Polyvinylchlorid) problematisch ist, da bereits die zwischen Schnecke, Granulat und Rohr auftretende Reibung zu einer Überhitzung führen kann und nur durch eine aufwendige Rückkühlung auszuschalten wäre.This welding device has proven itself in practice in many ways, however there are some use cases where it cannot be used. So allowed the fact that the welding material is granular and freely stored in the funnel, no handling of the welding machine in any position, so z. B. no welding overhead, as is the case with pipes, tube sheets or the like the welding material a-J would flow out of the funnel. It has also been shown that the Verweadung of PVC (polyvinyl chloride) is problematic, as already the The friction between the screw, the granulate and the pipe can lead to overheating can and can only be switched off by a complex recooling.
Der Erfindung liegt nunmehr die Aufgabe zugrunde, ein Schweißgerät der eingangs genannten Art so auszuge#-stalten, daß eine Handhabung in beliebiger Stellung sowie eine kontrollierte Temperaturführung und damit die Verwendung möglichst vieler auch in verarbeitungstechnischer Hinsicht problematischer thermoplastischer Kunststoffe, einschließlich PVC, möglich wird.The invention is now based on the object of a welding device of the type mentioned at the outset in such a way that handling in any Position as well as a controlled temperature control and thus the use if possible many thermoplastic ones that are also problematic in terms of processing technology Plastics, including PVC, becomes possible.
Gelöst wird die Aufgabe mit einem Schweißgerät der eingangs genannten Art, welches gekennzeichnet ist durch eine Förderkammer, an deren Anfang eine Einlaßöffnung für einen Schweißdraht sowie ein den Schweißdraht zu einem Granulat umformendes Zerkleinerungsorgan vorgesehen sind, wobei der Einlaßöffnung eine Transportvorrichtung für den Schweißdraht zugeordnet ist und das Schmelzrohr den Auslaß aus der Förderkammer bildet.The problem is solved with a welding device of the type mentioned at the beginning Kind, which is characterized by a delivery chamber, at the beginning of which an inlet opening for a welding wire and a welding wire that transforms the welding wire into granules Comminution members are provided, the inlet opening being a transport device is assigned for the welding wire and the melting tube is the outlet from the delivery chamber forms.
Im Gegensatz zu einem bekannten Schweißgerät, welches nach dem Dxtruder-Pr.nzip arbeitet, erfolgt jetzt eine Plastifizierung des Schweißmaterials ausschließlich durch von außen zugeführte Wärme. Das Schmelzrohr ist frei von jeglichem Förderelement, welches nunmehr in einer separaten Förderkammer angeordnet ist und nur noch die Aufgabe hat, Schweißmaterial dem Schmelzrohr zuzuführen und durch dieses hindurchzufördern.In contrast to a well-known welding device, which is based on the Dxtruder-Pr.nzip works, the welding material is now only plastified by externally supplied heat. The melting tube is free of any conveying element, which is now arranged in a separate delivery chamber and only the Has the task of supplying welding material to the melting tube and conveying it through it.
Bis zur Förderkammer gelangt das Schweißmaterial als zusammenhängendes Teil, nämlich als Schweißdraht, danach wird es zerkleinert und gelangt als Granulat in das Schmelzrohr. Den Transport des Schweißdrahtes in die Förderkammer bewirkt die spezielle Transportvorrichtung, welche den Schweißdraht kontinuierlich in die Einlaßöffnung einschiebt.The welding material reaches the conveying chamber as a cohesive one Part, namely as welding wire, then it is shredded and arrives as granules into the melting tube. Causes the welding wire to be transported into the conveying chamber the special transport device that carries the welding wire continuously into the Inlet opening pushes in.
Das erfindungsgemäße Schweißgerät gestattet damit ein kontinuierliches Arbeiten in beliebiger Stellung, auch über Kopf. Die Temperatur im Schmelzrohr läßt sich gut regeln, so daß Überhitzungen vermieden werden und auch in thermischer Hinsicht problematisches Schweißmaterial wie PVC verarbeitet werden kann.The welding device according to the invention thus allows a continuous Work in any position, even overhead. The temperature in the melting tube leaves regulate themselves well, so that overheating is avoided and also from a thermal point of view problematic welding material such as PVC can be processed.
Ein weiterer Vorteil besteht darin, daß das Schweißgerät nunmehr mit einer geringeren Antriebsleistung auskommt und sich damit sein Gewicht erheblich verringern läßt. So wiegt ein Schweißgerät zur Verarbeitung von-im Durchmesser 4 mm starken Schweißdrähten und Erzeugung einer 6 bis 12 mm starken Schweißraupe, mit dem Teile mit Wanddicken bis zu 20 mm verschweißt werden können, nur noch etwa 8 kg.Another advantage is that the welding machine is now with a lower drive power and thus its weight considerably can decrease. This is how a welding machine for processing - with a diameter of 4 mm thick welding wires and creation of a 6 to 12 mm thick welding bead, with which parts with a wall thickness of up to 20 mm can be welded, only about 8 kg.
Besonders günstig ist, wenn die Förderkammer an ihrem Anfang eine Kühinut aufweist.It is particularly favorable if the delivery chamber has a Has Kühinut.
In weiterer Ausgestaltung des Erfindungsgedankens ist das Zerkleinerungsorgan ein Rotationsteil mit an seinem Umfang angeordneten Schermessern od. dgl., welche die Einlaßöffnung überstreichen.The comminuting element is a further embodiment of the inventive concept a rotary part with shear blades arranged on its circumference or the like. Which paint over the inlet opening.
Vorteilhaft ist das Zerkleinerungsorgang einstückig mit dem Pörderelement ausgebildet, wobei das Pörderelement eine Schnecke ist.The comminuting element is advantageously in one piece with the conveying element formed, wherein the conveyor element is a screw.
Nach einem weiteren Vorschlag sind das Zerkleinerungsorgan) und das Förderelement einseitig mittels eines kombinierten Radial-Axiallagers gelagert.According to another suggestion, the comminuting organ) and the Conveying element mounted on one side by means of a combined radial-axial bearing.
Zweckmäßigerweise ist das Schmelzrohr im Abstand von einem Mantel umgeben, welcher mit einem Eintrittsstutzen am Anfang und einer Auslaßöffnung nahe der Mündung des Schmelzrohres zum Durchleiten von Heißluft versehen ist. - Diese Ausführungsform gestattet eine besonders schonende Temperaturführung.The melting tube is expediently at a distance from a jacket surrounded, which with an inlet port at the beginning and an outlet opening close the mouth of the melting tube is provided for the passage of hot air. - These Embodiment allows a particularly gentle temperature control.
Vorteilhaft ist die Auslaßöffnung, in Bewegungsrichtung gesehen, vor der Mündung des Schmelzrohres angeordnet.The outlet opening, viewed in the direction of movement, is advantageous the mouth of the melting tube arranged.
- Auf diese Weise läßt sich erreichen, daß die zu verschweißenden Teile gleichzeitig vorgewärmt werden, da di&' austretende Heißluft auf die Schweißstelle gerichtet ist und dem aus der Mündung des Schmelzrohres austretenden Schweißmaterial vorauseilt.- In this way it can be achieved that the to be welded Parts are preheated at the same time, as hot air escapes onto the welding point is directed and the welding material emerging from the mouth of the melting tube rushes ahead.
Eine besonders leichte Verarbeitung ist gewährleistet, wenn das Schmelzgerät an seiner bindung eine auswechselbare Düse aufweist und mit einem Schweißschuh versehen ist.Particularly easy processing is guaranteed if the melter has a replaceable nozzle on its binding and is provided with a welding shoe is.
Zweckmäßigerweise besteht die Transportvorrichtung aus einem angetriebenen Rollenpaar.The transport device expediently consists of a driven one Pair of rollers.
Vorteilhaft besitzt das Rollenpaar ein aus Schnecke und Schneckenrad bestehendes Getriebe, wobei die eine Rolle fest mit dem Schneckenrad verbunden und die andere Rolle freilaufend sowie gegen die erste Rolle anpreßbar ist und wobei die Schnecke mit dem Förderelement verbunden ist.The pair of rollers advantageously has a worm and worm wheel existing gearbox, one of which is firmly connected to the worm wheel and the other roller is free running and can be pressed against the first roller and wherein the screw is connected to the conveyor element.
Besonders einfach und preiswert ist ein erfindungsgemäßes Schweißgerät, wenn es über keinen eigenen Antrieb verfügt, sondern als Vorsatzgerät für eine f1andbohrmaschine ausgebildet ist.A welding device according to the invention is particularly simple and inexpensive, if it does not have its own drive, but rather as an attachment for a tapping machine is trained.
