Description

"Vorrichtung zum Verschweißen von einteiligen, mehrlagigen und/oder kaschierten Flächengebilden, Rohren o.dgl. aus thermoplastischen Kunststoffen1, Die Erfindung bezieht sich auf eine Vorrichtung zum Verschweißen von thermoplastischen Kunststoff-Fläohengebilden längs ihren Stoßfugen."Device for welding one-piece, multi-layer and / or laminated flat structures, pipes or the like. made of thermoplastics1, The invention relates to a device for welding thermoplastic Plastic planar structures along their butt joints.

In der Hauptsache sind zwei Schweißmethoden in der einschlägigen Technik gebräuchlich, und zwar das Erwärmen nach dem Heißluftverfahren und nach dem Lötkolbenprinzip. Beim Heißluftverfahren trifft der Luftstrom, der elektrisch oder durch eine Flamme direkt oder indirekt erhitzt wird, auf die, z. B. durch Fräsen o.dgl., vorbereitete Naht und erhitzt den Schweißdraht direkt oder indirekt. Hierbei wirkt sich nachteilig aus, daß die Heißluft nach ihrer Menge, Geschwindígteit, Temperatur und Kontaktzeit mit dem Schweißdraht sowie dem zu verschweißenden Werkstoff entweder überhaupt nicht oder nur in stark streuenden Bereichen reguliert werden kann. So ist es z.B. schwierig, die Schweißkanten der Werkstoff-Flächengebilde und den Schweißdraht gleichzeitig auf die günstigste Schweißtemperatur zu bringen.In the main, two welding methods are in the relevant technology common, namely the heating according to the hot air method and according to the soldering iron principle. In the case of the hot air process, the air flow hits the ground electrically or through a flame is heated directly or indirectly to which, for. B. by milling or the like., Prepared Seam and heats the welding wire directly or indirectly. This has a disadvantageous effect from that the hot air according to its amount, speed, temperature and contact time with the welding wire and the material to be welded either not at all or can only be regulated in highly scattering areas. For example, it is difficult the welding edges of the sheet material and the welding wire at the same time to bring it to the most favorable welding temperature.

Jegliche Temperaturdifferenz wirkt sich auf die Schweißgeschwindigkeit nachteilig aus, weil die Schweißvorrichtung in aller Regel zur Erzielung optimaler Ergebnisse so ausgelegt ist, daß sie mit einer einzigen bestimmten Geschwindigkeit gefahren werden muß. Eine Änderung der Schweißgeschwindigkeit hat eine Beeinträchtigung der Schweißnaht und eine Schädigung der Oberfläche des Sohweißgutes zur Folge.Any temperature difference will affect the welding speed disadvantageous because the welding device usually to achieve optimal Results is designed to be obtained with a single specific speed must be driven. Changing the welding speed has an adverse effect the weld seam and damage to the surface of the weld metal result.

Für das Verschweißen nach dem Lötkolbenprinzip ist es bekannt, den Schweißkolben elektrisch zu beheizen und die Heizung aus rein technischen Gründen in Stufen, z. B. von 400 - 600 - 1000 Watt, grob zu regulieren. Der erhitzte, meist schneidenartig ausgebildete Schweißkolben schmilzt eine V-Nut oder Hohlkehle längs der Stoßfuge und macht ein spanabhebendes Vorbereiten der Werkstoffkanten überflüssig.For welding by the soldering iron principle, it is known to the Electrically heating welding iron and heating for purely technical reasons in stages, e.g. B. from 400 - 600 - 1000 watts, roughly regulate. The heated welding iron, which is usually shaped like a cutting edge, melts a V-groove or fillet along the butt joint and make a machining preparation of the material edges superfluous.

Als Stand der Technik zum Verschweißen ist auch schon ein kombiniertes Schweißwerkzeug aus einer lotrechten Heizlamelle und einem waagrechten beheizten Verstreichschuh in Vorschlag gebracht worden.The state of the art for welding is already a combined one Welding tool consisting of a vertical heating lamella and a horizontal heated one Brushing shoe has been proposed.

Das Zusatzmaterial wird bei diesem Werkzeug vorverflüsæigt und in einen vorbereiteten Spalt eingebracht Als Nachteil hat sich bei diesem Aggregat die fehlende Regulierung der Aufheizung des Zusatzdrahtes von ### der Heizlamello ergeben.The additional material is pre-liquefied in this tool and in A prepared gap has been created as a disadvantage with this unit the lack of regulation of the heating of the additional wire from ### the heating lamello result.

Ferner haben die Lamelle und der Streichschuh die gleiche Temperatur; hierdurch neigt der Schuh zum Ankleben. Der BehelS der Anwendung von nertem Gas vermag Zersetzungserscheinungen, z. B. bei Polyvinylchlorid,infolge zu langer Verweilzeit, nicht zu verhindern.Furthermore, the lamella and the fettering shoe have the same temperature; as a result, the shoe tends to stick. The means of using inert gas capable of decomposition, e.g. B. with polyvinyl chloride, due to too long residence time, not to prevent.

Der Erfindung liegt nun die Aufgabe zugrunde, eine von Hand oder mechanisch bewegbare Schweißvorrichtung zu schaffen, mit der ein Verscliweißen von Kunststoff-Flächengebilden, Rohren @.dgl. bei einwandfreier Qualität der Schweißnaht gewährleistet ist. Gelöst wird diese Aufgabe gemäß der Erfindung in der Weise, daß, ausgehend von dem üblichen Verschweißen von Kunststorfen, bei den ein thermisch erweichter Kunststoff-Schweißdraht in die Schweißnaht gepreßt wird, an einem von Hand oder maschinell bewegten, beheizbaren Schweißblock aus wärmeleitendem Werkstoff, wie z.B. Kupfer, eine den Schweißdraht erfassende und ihn in die Schweißnaht pressende Andrückrolle gehaltert und ein profiliertes Schweißschwert an der Basisfläche des Sohweißblocks vorgesehen ist. Es hat sich als vorteilhaft erwiesen, die Andrückrolle auf ihrem Umfang als gerändelte Hohlkehle auszubilden. In Abhängigkeit von den örtlichen Gegebenheiten ist es ferner zweckmässig, die Andrückrolle verschiebbar zu lagern und ihren Anpreßdruck durch eine Feder einstellbar zu gestalten.The invention is based on the object, a manually or mechanically to create a movable welding device with which a welding of plastic flat structures, Pipes @. The like. with perfect quality of the weld seam is guaranteed. Solved this object according to the invention in such a way that, starting from the usual Welding of plastic parts using a thermally softened plastic welding wire is pressed into the weld seam, on a manually or mechanically moved, heatable Welding block made of thermally conductive material, such as copper, for the welding wire gripping and pressing it into the weld seam held and a profiled Welding sword is provided on the base surface of the Sohweißblock. It has proved to be advantageous, the pressure roller on its circumference as a knurled groove to train. Depending on the local conditions, it is also advisable to to store the pressure roller displaceably and its contact pressure by to make a spring adjustable.

Erfindungsgemäß ist das Schweißschwert an dem beheizbaren Sohweißblock auf seiner ganzen Länge in bestimmter Weise profiliert und zwar stetig verbreitert, derart, daß sich z. B. der Steg des Schwertes von Do° auf 9o° bzw. Halbkreisform erweitert.According to the invention, the welding sword is on the heatable welding block profiled in a certain way along its entire length and steadily widened, such that z. B. the bar of the sword from Do ° to 9o ° or semicircular shape expanded.

Für das Verschweißen von kaschierten Flächengebilden ist es zweckdienlich, einen am Schweißblock drehbar angeordneten Vorlaufschuh vorzusehen, der an seiner Spitze pflugscharartig ausgebildet ist und an seiner Gleitsohle z.B. eine Roll çchneide o.dgl. als Führungselement für den Schweißblock aufnimmt.For the welding of laminated flat structures, it is useful to to provide a rotatably arranged on the welding block advancing shoe on his Tip is designed like a ploughshare and on its sliding sole e.g. a roller cutter or the like. takes up as a guide element for the welding block.

Praktische Versuche haben ergeben, daß es von besonderer Bedeutung sein kann, alle gleitenden und/oder beweglichen Einzelglieder der Schweißvorrichtung, wie z.B. die Andrückrolle, den Vorlaufschuh etc., mit Polytetrafluoräthylen zu überziehen oder zu verchromen.Practical tests have shown that it is of particular importance can be, all sliding and / or movable individual links of the welding device, such as the pressure roller, the feed shoe, etc., to be covered with polytetrafluoroethylene or to chrome.

In der Zeichnung ist ein Ausführungsbeispiel der Schweißvorrichtung gemäß der Erfindung dargestellt und zwar zeigt: Fig. 1 - die SchweißvorrichtunO in der Seitenansicht ; Fig. 2 - die chweißvorrichtung im Schnitt A - B; Fig. 5-den Verlauf des Schweißschwertes vom Punkt 17 im kontinuierlichen Übergang bis Punkt 18; Fig. 4 - das Profil des Glättschuhes.In the drawing is an embodiment of the welding device shown according to the invention, namely: Fig. 1 - the welding device in side view; Fig. 2 - the welding device in section A - B; Fig. 5-den Course of the welding sword from point 17 in a continuous transition to point 18; Fig. 4 - the profile of the smoothing shoe.

Der Schweißblock 1 besteht aus Wärme gut- leitendem Material, z. B. Kupfer o.dgl., und wird über Zu-und Ableitungen 2, 3 u.2', 3' durch eine Flüssigkeit beheizt, deren Temperatur nach den praktischen Erfahrungen ungefähr 150 bis 180t beträgt und durch ein an sich bekanntes Heizelement laufend eingestellt wird. Der Zusatzdraht 4, der vorzugsweise von runder Gestalt ist und keine Orientierung hinsichtlich seines Umfangs erforderlich macht, weist einen Querschnitt auf, der gleich oder wenig größer ist als der Querschnitt der vorbereiteten Schweißfuge, um ein unnötiges Erwärmen des Schweißdrahtes zu vermeiden, durch welches die Schweißgeschwindigkeit beeinträchtigt würde.The welding block 1 consists of a material that conducts heat well, e.g. B. Copper or the like., And is via supply and discharge lines 2, 3 and 2 ', 3' through a liquid heated, the temperature of which, according to practical experience, is approximately 150 to 180t and is continuously adjusted by a known heating element. Of the Additional wire 4, which is preferably round in shape and does not provide any orientation with regard to its circumference requires, has a cross-section that is equal to or is slightly larger than the cross-section of the prepared weld joint to avoid unnecessary Avoid heating the welding wire, by which the welding speed would be affected.

Für die Zuführung des Schweißdrahtes 4 ist der Schweißblock endweise bei 5 zur Schmeizfuge ausgebildet. An dem Schweißblock 1 ist mit Hilfe einer Halterung 6 die Andrilokrolle 7 vorgesehen, die zur Regulierung des AnpreBdruckes des Schweißdrahtes 4 durch eine Feder 8 einstellbar ist. Die Rolle 7 weist entsprechend der fertigen Schweißraupe eine Hohlkehle 9 auf, die zwecks gesicherter Mitnahme des Schweißdrahtes gerändelt ist. Der runde Schweißdraht wird beim Durchlaufen zwischen der Andrückrolle 7 und des Sch * fuge 5 profiliert angeschmolzen und vorgewärmt, wobei der Profilwinkelquerschnitt kleiner ist als der vorgeschmolzene Stoßfugenwinkel.For the feeding of the welding wire 4, the welding block is formed endwise at 5 to form the fusion joint. On the welding block 1, the andrilok roller 7 is provided with the help of a holder 6, which can be adjusted by a spring 8 to regulate the contact pressure of the welding wire 4. The roller 7 has a fillet 9 corresponding to the finished welding bead, which is knurled for the purpose of securing the entrainment of the welding wire. The round welding wire is when passing between the pressure roller 7 and of Sch * fuge 5 profiled melted and preheated, the profile angle cross-section being smaller than the pre-melted butt joint angle.

Die Basisfläche des Schweißblocks 1 ist erfindungsgemäß als Schweißschwert lo ausgebildet, dessen Profilsteg von 300 bis 9o0 aut seiner ganzen Länge stetig zunimmt oder im BedarSsfall bis zur Hohlkehle-sich erweitert, wie dies beispielsweise in der Fig. 3 veranschaulicht ist. Die Länge des Schweißschwertes lo ist so bemessen, daß in aller Regel ein ausreichender Wärmeübergang vom Schweißschwert auf das thermoplastische Schweißgut bei der im Bedarfsfall gerade erforderlichen Schweißtemperatur ermöglicht ist. Das Schweißschwert lo hat auf diese Weise einerseits den benötigten Wärmekontakt mit den Schweißkanten des Schweißgutes, quetscht andererseits entsprechend der Profilzunahme das geschmolzene Material weg und hält wegen der geringen Wärmeleitfähigkeit des thermoplastischen Materials laufend unmittelbaren Kontakt mit neuem Material. Nach Fig. 4 besitzt der Schweißblock 1 eine beheizte Glätteinrichtung, die von einer Hohlkehle 19 in eine plane Fläche 20 übergeht und den Schweißdraht glattbügelt.According to the invention, the base surface of the welding block 1 is a welding sword lo formed, whose profile web from 300 to 9o0 aut its entire length steadily increases or, if necessary, expands up to the fillet, such as this, for example is illustrated in FIG. 3. The length of the welding sword lo is dimensioned so that, as a rule, sufficient heat transfer from the welding sword to the thermoplastic Allows welding material at the welding temperature just required if necessary is. In this way, the welding sword lo has, on the one hand, the required thermal contact with the welding edges of the weld metal, on the other hand, squeezes according to the increase in profile the melted material away and holds because of the low thermal conductivity of thermoplastic material, constant direct contact with new material. To Fig. 4, the welding block 1 has a heated smoothing device, which is of a The fillet 19 merges into a flat surface 20 and ironed the welding wire smooth.

Soll überdies im Bedarfsfall z. B. ein filzkaschierter PVO-Sußbodenbelag geschweißt werden, so erhält das Schweißschwert lo einen Vorlaufschuh 11, welcher die Filzkanten vorübergehend anhebt und die Falzkanten in dieser Lage bis zum Beginn des Schweißvorganges hält. Hierdurch wird der Vorteil erzielt, daß der Filz im Bereich der Schweißfuge vor dem Verschweißen nicht durch eine besondere Maßnahme entfernt werden muß. Der zusätzliche Vorlaufschuh 11 ist an dem Punkt 12 am Schweißblock 1 drehbar gelagert. Er ist an seiner Spitze 13 pflugscharartig abgeschrägt. Ferner dient die Spitze des Vorlaufschuhs gemeinsam mit der Andrückrolle 7 als 2 Punkt-Auflage zur Einstellung der Eindringtiefe des Schweißschwertes lo. Pür die einwandfreie Führung des Schweißschwertes in der Schweißfuge ist an der Gleitsohle des Vorlaufschuhs ein besonderes Führungselement, z. B. in Gestalt einer Rolle, Rasierklinge oder Schiene 14, vorgesehen.Should also, if necessary, for. B. a felt-laminated PVO floor covering are welded, the welding sword lo receives a lead shoe 11, which the felt edges temporarily lifts and the folded edges in this position until the beginning of the welding process. This has the advantage that the felt in the area the welding joint is not removed by a special measure before welding must become. The additional lead shoe 11 is at point 12 on the welding block 1 rotatably mounted. It is beveled at its tip 13 like a ploughshare. Further the tip of the feed shoe together with the pressure roller 7 serves as a 2-point support for setting the penetration depth of the welding sword lo. Pür the flawless The welding sword is guided in the welding joint on the sliding sole of the leading shoe a special guide element, e.g. B. in the form of a role, razor blade or Rail 14 is provided.
