Abstract
Description
Die Erfindung betrifft ein Schweißgerät, insbesondere Dicknaht-Schweiß gerät, zur Verarbeitung von thermoplastischem Kunststoff-Schweißdraht gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a welding device, in particular thick seam welding device, for processing thermoplastic welding wire according to the preamble of claim 1.
Ein derartiges Schweißgerät ist aus der DE-PS 32 21 492 bekannt. Weiter ist ein derartiges Gerät in der DE-OS 28 23 171 beschrieben. Derartige Geräte haben sich in der Praxis sehr gut bewährt, so daß deren Einsatzbereich immer größer wurde. Besonders für Montagearbeiten ist es aber erstrebenswert, die Geräte noch kompakter zu bauen. Anderer seits besteht der Wunsch, dickere Schweißdrähte zu verarbeiten. Dem sind durch die bekannten Geräte, bedingt durch die Schweißdrahtum lenkung, Grenzen gesetzt.Such a welding device is known from DE-PS 32 21 492. Such a device is further described in DE-OS 28 23 171. Such devices have proven themselves very well in practice, so that their Area of application became ever larger. Especially for assembly work but it is desirable to make the devices even more compact. Other on the one hand, there is a desire to process thicker welding wires. The are due to the known devices, due to the welding wire steering, limits.
Aufgabe der vorliegenden Erfindung ist es, ein Gerät der eingangs genannten Art zu schaffen, das sehr kompakt baut und auch dicke, wenig biegsame Schweißdrähte ver arbeiten kann.The object of the present invention is to provide a device of the type mentioned at the outset very compact and also thick, less flexible welding wires can work.
Dies wird mit den kennzeichnenden Merkmalen des Anspruchs 1 erreicht. Durch die besondere Ausführung der Förderschraube baut das Gerät deut lich kürzer; es findet keine Umlenkung des Schweißdrahtes statt, so daß auch dicke Schweißdrähte und -stangen problemlos verarbeitet werden können.This is achieved with the characterizing features of claim 1. Due to the special design of the screw, the device builds significantly slightly shorter; there is no deflection of the welding wire, so that even thick welding wires and rods can be processed without any problems can.
Weitere Ausführungsbeispiele der Erfindung sind den Unteransprüchen zu entnehmen. So bietet es sich an, durch mehrere Zuführkanäle unter schiedlichen Durchmessers bei Einfachgeräten ganz auf einen Dickenaus gleich zu verzichten. Des weiteren kann der Dickenausgleich für Univer salgeräte austauschbar für verschiedene Schweißdrahtdurchmesserbereiche ausgelegt werden.Further embodiments of the invention are the subclaims refer to. So it makes sense to go through several feed channels different diameters for single devices to a thickness to renounce right away. Furthermore, the thickness compensation for Univer Sal devices interchangeable for different welding wire diameter ranges be interpreted.
Zwei Ausführungsbeispiele der Erfindung werden im folgenden anhand der Zeichnungen näher erläutert. Es zeigtTwo embodiments of the invention are described below of the drawings explained in more detail. It shows
Fig. 1 einen Längsschnitt durch eine Fördereinrichtung eines Dick naht-Schweißgerätes, Fig. 1 shows a longitudinal section through a conveyor of a thick-seam welding apparatus,
Fig. 2 einen Schnitt gemäß der Linie II-II nach Fig. 1, Fig. 2 shows a section according to line II-II of FIG. 1,
Fig. 3 eine Alternativlösung einer Fördereinrichtung mit einer rechtwinklig zum Zerkleinerungs- und Förderelement liegenden Förderschraube, Fig. 3 shows an alternative solution, a conveyor device with a right angles to the crushing and conveying element conveying screw,
Fig. 4 einen Schnitt gemäß der Linie IV-IV nach Fig. 3 und Fig. 4 is a section along the line IV-IV of Fig. 3 and
Fig. 5 einen Schnitt gemäß der Linie V-V nach Fig. 3. Fig. 5 shows a section according to line VV of FIG. 3.
In einer Förderkammer 1 läuft ein Zerkleinerungs- und Förderelement 2, das axial mit einer Welle 3 eines nicht dargestellten Antriebs ge koppelt ist. Auf diese Welle 3 ist eine Fördereinrichtung 4 aufgeflanscht. Die Fördereinrichtung 4 besteht aus einer radial steigenden Förder schraube 5, einem zu dieser Steigung parallel verlaufenden Zuführkanal 6 und einem Dickenausgleich 7. Mit 8 ist ein Gehäuse gekennzeichnet.In a conveying chamber 1 runs a crushing and conveying element 2 , which is axially coupled to a shaft 3 of a drive, not shown. A conveyor 4 is flanged onto this shaft 3 . The conveyor 4 consists of a radially rising screw 5 , a parallel to this slope feed channel 6 and a thickness compensation 7th A housing is identified by 8 .
Im Schnitt gemäß Fig. 2 sind zwei weitere Zuführkanäle 9 und 10 mit unterschiedlichen Durchmessern dargestellt. Die Dickenausgleichschieber 7 sind durch Federn 11 unter geringer Vorspannung gehalten, so daß auch bei Dickentoleranzen des Schweißdrahtes eine sichere Mitnahme in der Förderschraube erfolgt. Der Schweißdraht 12 wird absolut gerad linig zugeführt, so daß auch Schweißstäbe verarbeitet werden können.In the section according to FIG. 2, two further feed channels are shown with different diameters 9 and 10. The thickness compensating slide 7 are held by springs 11 under low pretension, so that even in the case of thickness tolerances of the welding wire there is a safe entrainment in the feed screw. The welding wire 12 is fed absolutely straight line, so that welding rods can also be processed.
In Fig. 3 ist eine Alternativlösung einer Fördereinrichtung, die noch kompakter baut, dargestellt. Die Förderschraube 5′ ist auf der senkrecht zur Antriebsachse 13 verlaufenden Stirnfläche mit einem Radialgewinde 14 versehen. Die Zuführkanäle 15, 16 und 17 unterschiedlichen Durch messers verlaufen parallel zum Radialgewinde 14 in Richtung Geräteachse 13. Mit 18 sind die Dickenausgleichsschieber gekennzeichnet, 19 kennzeichnet ein radiales Gleitlager, 20 ein axiales Drucklager.In Fig. 3 an alternative solution of a conveyor, which is even more compact, is shown. The screw 5 ' is provided on the perpendicular to the drive axis 13 end face with a radial thread 14 . The feed channels 15, 16 and 17 of different diameters run parallel to the radial thread 14 in the direction of the device axis 13 . The thickness compensation slide is identified by 18 , 19 denotes a radial slide bearing, 20 an axial thrust bearing.
