Description

Löt- bzw. Schweissvorrichtung für LängsprofileSoldering or welding device for longitudinal profiles

Löt- bzw Schweissvorrichtung für Längsprofile Die Erfindung betrifft eine Löt- bzw Schweissvorrichtung für Längsprofile, wie Rohre, Stangen und dergleichen, mit einem die Löt- bzw Schweissstelle umgebenden, die Wärmequelle tragenden Gehäuse. Soldering or welding device for longitudinal profiles The invention relates to a soldering or welding device for longitudinal profiles such as pipes, rods and the like, with a housing that surrounds the soldering or welding point and carries the heat source.

Vorrichtungen der genannten Art werden beispielsweise für das Verbinden von Rohren, Befestigen von Muffen, Fittingen und dergleichen verwendet. Das Material der zu verlötenden bzw zu verschweissenden Teile kann von metallischen bis zu nichtmetallischen Werkstoffen, wie beispielsweise Kunststoffe, reichen. Während bei-Kunststoffen die Werkstücke selbst, ohne Zuhilfenahme von Zusatzmitteln, miteinander verschweisst werden, handelt es sich bei Werkstücken aus metallischen Werkstoffen in der Regel um eine Verbinndung auf Hartlötbasis. Im letzteren Falle finden an sich bekannte, auf die Materialien der zu verbindenden Werkstücke abgestimmte Lotformteile Anwendung.Devices of the type mentioned are used, for example, for connecting used for pipes, fastening of sleeves, fittings and the like. The material the parts to be soldered or welded can range from metallic to non-metallic Materials such as plastics are sufficient. While in the case of plastics the Workpieces themselves welded together without the aid of additives workpieces made of metallic materials are usually involved a braze-based connection. In the latter case, known per se, solder preforms matched to the materials of the workpieces to be connected.

Zum Erzeugen der für die geschilderten Verfahren erforderlichen Wärme, sind verschiedene Wärmequellen bekannt. Nebst der Flammerwärmung mit ihren Nachteilen, wie Gefahr einer örtlichen Ueberhitzung, Verschmutzung, Brandgefahr und dergleichen, ist insbesondere die induktive Hochfrequenzerhitzung verbreitet. Bei letzterer Erwärmungsart besteht der grösste Nachteil darin, dass Abstimmungen auf Form und Material der zu verlötenden bzw zu verschweissenden Werkstücke einzuhalten sind. So ist eine optimale Erwärmung beispielsweise nur dann gegeben, wenn die Induktionsspulen den Werkstücken angepasst sind. Ausserdem erfordern solche Wärmequellen grosse Hochfrequenz-Generatorleistungen, insbesondere bei Nichteisen-Metallen. Dies bedingt teuere Einrichtungen, deren grosser apparativer Aufwand nur noch den Bau von stationären Anlagen zulässt.To generate the heat required for the processes described, various heat sources are known. In addition to flame heating with its disadvantages, such as the risk of local overheating, pollution, fire risk and the like, inductive high-frequency heating is particularly widespread. With the latter type of heating The biggest disadvantage is that there are adjustments to the shape and material of the Workpieces to be soldered or welded must be observed. So is one For example, optimal heating is only given when the induction coils Workpieces are adapted. In addition, such heat sources require large high-frequency generator outputs, especially with non-ferrous metals. This requires expensive facilities, their larger ones expenditure on equipment only allows the construction of stationary systems.

Für anderweitige Anwendungszwecke ist es bekannt geworden, die Energie einer Infrarotlampe mittels Spiegeln in einem Arbeitsbrennpunkt zu bündeln und die damit erzeugte optische Abbildung als Wärmequelle zu benutzen. Aufgrund der optischen Abbildung ist der Arbeitsbrennpunkt in seiner Lage genau vorbestimmt. Abweichungen können bereits dazu führen, dass die erforderliche Wärme nicht mehr übertragen wird. Aus diesem Grunde hat sich diese Art der Wärmeerzeugung lediglich auf Spezialgebieten, beispielsweise beim Präzisions-Apparatebau, durchsetzen können. Ueberdies muss ein erheblicher Aufwand hinsichtlich der richtigen Dosierung getrieben werden, da die punkt- bzw linienförmigen Erwärmungszonen örtliche Ueberhitzungen mit damit verbundenen Materialschädigungen der Werkstücke zur Folge haben können.For other purposes it has become known, the energy to focus an infrared lamp by means of mirrors in a working focal point and the to use thus generated optical image as a heat source. Because of the optical The position of the working focus is precisely predetermined. Deviations can already result in the required heat no longer being transferred. For this reason, this type of heat generation has only proven itself in special areas, for example in precision apparatus construction. In addition, a must considerable effort is made with regard to the correct dosage, since the point or line-shaped heating zones local overheating with associated Can result in material damage to the workpieces.

Für das Verbinden von Rohren ist eine Löt- bzw Schweissvorrichtung aus der DE-OS 2 124 868 bekannt, deren Wärmequelle elektrische Widerstände bilden. Dieses Gerät, welches sich wohl für den nichtstationären Einsatz eignet, weist aber die üblichen Nachteile eines auf Widerstandserwärmung basierenden Gerätes auf, wie grosser Energieverbrauch, aufwendige Isoliereinrichtungen und lange Aufheiz- bzw Abkühlungszeiten.A soldering or welding device is available for connecting pipes from DE-OS 2 124 868 known, the heat source of which forms electrical resistances. However, this device, which is suitable for non-stationary use, shows the common drawbacks of resistance heating based equipment such as large energy consumption, expensive insulating devices and long heating or Cool down times.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, unter Vermeidung der vorstehend angeführten Nachteile, eine handliche, sich für die Bearbeitung von Längsprofilen eignende Löt- bzw Schweissvorrichtung zu schaffen.The object of the present invention is to avoid it of the disadvantages listed above, a handy one for editing To create suitable soldering or welding devices for longitudinal profiles.

Erfindungsgemäss wird die Aufgabe dadurch gelöst, dass die Wärmequelle aus zwei oder mehreren die Strahlungswärme direkt auf die Löt- bzw Schweissstelle abgebenden Infrarotstrahlern besteht.According to the invention, the object is achieved in that the heat source from two or more the radiant heat directly to the soldering or welding point emitting infrared radiators.

Die erfindungsgemäss vorgeschlagene Anordnung der Infrarotstrahler hat den Vorteil, dass unter Ausnützung aller Vorzüge einer diesbezüglichen Wärmequelle eine grossflächige Löt- bzw Schweissstelle gleichmässig erwärmt werden kann. Dies ist insbesondere bei der Bearbeitung von Längsprofilen in vorerwähnter Weise wichtig, da es sich in diesen Fällen immer um grosse Flächen, dh Mantelflächen handelt, die einer gleichmässigen Erwärmung unterliegen müssen. Die Anzahl der vorzusehenden Infrarotstrahler richtet sich nach Grösse und Form der zu erwärmenden Werkstücke. Massgebend ist diesbezüglich vor allem das Erfordernis einer gleichmässigen Bestrahlung, was in der Regel ein mehr oder weniger vollständiges Umgeben der Löt- bzw Schweissstelle mit Infrarotstrahlern erfordert.The arrangement of the infrared radiators proposed according to the invention has the advantage of utilizing all the advantages of a related heat source a large-area soldering or welding point can be heated evenly. this is particularly important when machining longitudinal profiles in the aforementioned way, because in these cases it is always a question of large areas, ie lateral surfaces that must be subject to uniform heating. The number of to be provided Infrared heater depends on the size and shape of the workpieces to be heated. In this regard, the requirement for uniform irradiation is decisive, which is usually a more or less complete surrounding of the soldering or welding point with infrared heaters required.

Die gleichmässige Bestrahlung und die daraus resultierende Erwärmung der zu bearbeitenden Längsprofile kann im wesentlichen dadurch gefördert werden, dass die Infrarotstrahler die Löt- bzw Schweisstelle umgeben und zudem im gleichen Abstand davon angeordnet sind. Bei der Bearbeitung von Rohren sind die Infrarotquellen demnach immer im selben Abstand von der Mantelfläche angeordnet, was den grossen Vorteil hat, dass jeder Teilbereich der Mantelfläche einer gleichmässig verteilten Erwärmung unterworfen ist.The uniform irradiation and the resulting warming the longitudinal profiles to be processed can essentially be promoted by that the infrared emitters surround the soldering or welding point and also in the same place Spaced therefrom. When processing pipes, the infrared sources are therefore always arranged at the same distance from the lateral surface, which is the big It has the advantage that each sub-area of the lateral surface is evenly distributed Is subject to heating.

Als Wärmequellen finden zweckmässigerweise Infrarotstrahler, die aus einem die Heizwendel umgebenden Quarzrohr bestehen, Anwendung.The heat sources expediently find infrared radiators from consist of a quartz tube surrounding the heating coil, application.

Das Quarzrohr kann evakuiert oder mit einem speziellen Gas, beispielsweise Halogen, gefüllt sein. Ueberdies ist es von Vorteil, wenn die Strahler eine kurze Baulänge aufweisen, so dass möglichst viel Energie innerhalb einer kurzen Zone abgegeben wird. Ausserdem ermöglicht eine kurze Baulänge den Bau einer handlichen Vorrichtung.The quartz tube can be evacuated or with a special gas, for example Halogen, be filled. It is also advantageous if the radiator is short Have overall length so that as much energy as possible is released within a short zone will. In addition, a short overall length enables the construction of a handy device.

Zur Verbesserung der Energieabgabe ist es weiterhin von Vorteil, wenn die Infrarotstrahler einen Reflektor aufweisen, der die Strahlung auf die Löt- bzw Schweissstelle reflektiert. Ein solcher Reflektor kann beispielsweise durch Aufdampfen einer diesbezüglichen Schicht auf das Quarzrohr hergestellt werden. Zum Aufdampfen eignen sich die für solche Zwecke bekannten Materialien, wie Gold und dergleichen. Der Reflektor hat nicht etwa die Aufgabe, die Strahlung zu bündeln und eine optische Abbildung zu schaffen, er soll vielmehr die Strahlung gegenüber derjenigen Seite abschirmen, wo sie nicht verwendet wird. Die Anordnung und Abmessung der Schicht richtet sich daher nach der Bauart der Vorrichtung.To improve the energy output, it is also advantageous if the infrared emitters have a reflector that directs the radiation onto the soldering or soldering Weld point reflected. Such a reflector can, for example, by vapor deposition a related layer can be produced on the quartz tube. For vapor deposition the materials known for such purposes, such as gold and the like, are suitable. The reflector does not have the task of bundling the radiation and creating an optical one To create an image, it should rather have the radiation opposite that side shield where it is not used. The arrangement and dimensions of the layer therefore depends on the design of the device.

Zur Verhinderung einer allfälligen Verschmutzung der Infrarotstrahler durch von der Löt- bzw Schweissstelle wegtretende Dämpfe oder Spritzer kann ein als optisches Filter dienendes Schutzglas vorgesehen sein. Mit einem solchen Schutzglas kann erreicht werden, dass einerseits die Blendwirkung herabgesetzt wird und andererseits die vom Infrarotstrahler abgestrahlte Wärme nahezu reflexionsfrei hindurchtreten kann, jedoch nicht die vom zu bearbeitenden Teil abgestrahlte Wärme. Die Aufheizung der gesamten Vorrichtung kann dadurch herabgesetzt werden.To prevent any contamination of the infrared heater due to vapors or splashes escaping from the soldering or welding point, a be provided as an optical filter serving protective glass. With such a protective glass it can be achieved that on the one hand the glare effect is reduced and on the other hand the heat emitted by the infrared heater can pass through almost without reflection can, but not the heat radiated from the part to be machined. The heating up the entire device can thereby be reduced.

Zur weiteren Herabsetzung der Blendwirkung kann nebst oder anstelle des Schutzglases ein separater Blendschutz vorgesehen sein, welcher zB die Form eines bienenwabenartigen Rasters haben kann.To further reduce the glare effect, in addition to or instead of the protective glass a separate glare protection can be provided, which, for example, the shape a honeycomb-like grid may have.

Ein solcher Blendschutz muss keine separaten wärmetechnischen Bedingungen erfüllen, er dient vielmehr dem Schutze der Bedienungsperson. Einen ähnlichen Zweck können Einrichtungen zur seitlichen Abschattung erfüllen. Solche Einrichtungen können beispielsweise austauschbare Abdeckbleche bilden, oder es können im Hinblick auf Form- und Toleranzüberbrückungen Bürsten aus Asbest oder sonstigem wärmebeständigem Material Anwendung finden.Such a glare protection does not need any separate thermal conditions meet, it rather serves to protect the operator. A similar purpose can meet devices for lateral shading. Such facilities can For example, interchangeable cover plates form, or it can with regard to Shape- and tolerance bridging brushes made of asbestos or other heat-resistant material Find application.

Je nach Anwendungsbereich und Form der zu erwärmenden Werkstücke können die Infrarotstrahler derart angeordnet sein, dass die Löt-bzw Schweissstelle davon vollständig umgeben ist. Sowohl bei einem nicht vollständigen Umgeben der Löt- bzw Schweissstelle von Infrarotstrahlern als auch bei einer vollständigen Umhüllung durch solche Elemente ist es gemäss einem weiteren Vorschlag der Erfindung von Vorteil, wenn Hilfsreflektoren vorgesehen sind, welche unter Einschluss der Infrarotstrahler die Löt- bzw Schweissstelle umgeben. Dadurch wird die gleichmässige Wärmeverteilung wesentlich gefördert und es werden selbst Stellen bestrahlt, welche aus formlichen oder baulichen Gründen benachteiligt wären. Auch ein solcher Hilfsreflektor, welcher nebst dem bereits erwähnten Reflektor des Infrarotstrahlers angeordnet sein kann, hat keine optische Abbildung der Wärmequelle zu schaffen, so dass es sich nicht um einen optisch exakten Spiegel handeln muss. Der Hilfsreflektor kann dementsprechend einfach, beispielsweise unter Verwendung einer Aluminiumfolie, ausgestaltet sein.Depending on the area of application and the shape of the workpieces to be heated, the infrared radiator can be arranged in such a way that the soldering or welding point thereof is completely surrounded. Both when not completely surrounding the soldering or Welding point of infrared radiators as well as a complete enclosure by means of such elements, according to a further proposal of the invention, it is advantageous if auxiliary reflectors are provided, which include the infrared radiator surround the soldering or welding point. This ensures even heat distribution significantly promoted and even areas are irradiated, which from formal or structural reasons would be disadvantaged. Also such an auxiliary reflector, which can be arranged next to the already mentioned reflector of the infrared heater, does not create an optical image of the heat source, so it is not must be an optically exact mirror. The auxiliary reflector can accordingly be designed simply, for example using an aluminum foil.

Zur Verhinderung einer Oxydation der Löt- bzw Schweissstelle kann die erfindungsgemässe Vorrichtung in Verbindung mit der Anwendung eines Schutzgases betrieben werden. Zu diesem Zwecke können im Gehäuse Austrittsöffnungen, die der Zuführung des Schutzgases auf die Löt- bzw Schweisstelle dienen, angeordnet sein. Im Falle, dass die Infrarotstrahler von einem Hilfsreflektor umgeben sind, kann dieser die erforderlichen Austrittsöffnungen aufweisen. Für die Zuleitung des Schutzgases kann das Gehäuse einen entsprechenden Anschlussstutzen aufweisen. Um eine Kühlung der Löt- bzw Schweissstelle durch das Schutzgas zu verhindern, sind die Austrittsöffnungen derart anzuordnen, dass der Gasstrom die Arbeitsstelle nicht direkt beaufschlagt. Zweckmässigerweise ist das Schutzgas durch vorzeitiges Bestreichen der Strahlungselemente vor schlussendlicher Zuführung zur Löt- bzw Schweissstelle aufzuwärmen.To prevent oxidation of the soldering or welding point the device according to the invention in connection with the use of a protective gas operate. For this purpose, outlet openings that the Supply of the protective gas to the soldering or welding point serve, be arranged. In the event that the infrared radiators are surrounded by an auxiliary reflector, can this have the required outlet openings. For the supply of the protective gas the housing can have a corresponding connection piece. To a cooling The outlet openings are to prevent the soldering or welding point from being caused by the shielding gas to be arranged in such a way that the gas flow does not act directly on the work site. The protective gas is expediently provided by premature coating of the radiation elements to be heated up before the final supply to the soldering or welding point.

Insbesondere bei einer als Handgerät ausgebildeten Vorrichtung, welche aus Handlichkeitsgrunden eine entsprechend geringe Masse aufzuweisen hat, wirkt sich eine Kühleinrichtung für die Infrarotstrahler vorteilhaft aus. Als Kühlmittel kann Luft, Wasser oder Gas Anwendung finden. Für die Kühlung kann ein gesonderter Kreis vorgesehen sein, wobei sich dafür insbesondere der rückwärtige Raum eines allenfalls vorhandenen Hilfsreflektors anbietet.In particular in the case of a device designed as a hand-held device, which has a correspondingly low mass for reasons of handiness, acts a cooling device for the infrared emitters advantageous the end. Air, water or gas can be used as the coolant. For cooling a separate circle can be provided, in particular the rear circle Offers space for any auxiliary reflector that may be present.

Nachdem nebst dem erzielten Handhabungskomfort eine Kühlung aus der Sicht der Infrarotstrahler von Vorteil ist, sind insbesondere die Verbindungsstellen zwischen Infrarotstrahler und Gehäuse in ausreichendem Masse zu kühlen. Im Falle einer Verwendung von Gas als Kühlmittel kann durch geeignete Bauart eine Kombination mit einem allfällig ohnehin erforderlichen Schutzgas gefunden werden.After, in addition to the achieved handling comfort, cooling from the From the point of view of the infrared radiator, the connection points are particularly advantageous to cool sufficiently between the infrared heater and the housing. In the event of a use of gas as a coolant can be a combination by suitable design can be found with a protective gas that may be required anyway.

Sowohl aus der Sicht der Kühlung als auch vom Standpunkt der Verschmutzung und Oxydation, kann die Anordnung einer Absaugvorrichtung für Dämpfe bzw Gase, gegebenenfalls kombiniert mit vorausgegangenen Massnahmen, von Vorteil sein.Both from the point of view of cooling and from the point of view of pollution and oxidation, the arrangement of a suction device for vapors or gases, if necessary combined with previous measures, be an advantage.

Wie bereits vorgängig erwähnt, besitzt die erfindungsgemässe Vorrichtung alle Eigenschaften, die an ein universell einsetzbares Handgerät gestellt werden. Zu diesem Zwecke kann die Vorrichtung in konstruktiver Hinsicht aus Gehäuse und Handgriff bestehen, wobei das Gehäuse als zangenartiger Lötkopf ausgebildet sein kann.As already mentioned above, the device according to the invention has all the properties that are required of a universally applicable handheld device. For this purpose, the device can be constructed in terms of housing and Handle exist, the housing being designed as a pliers-like soldering head can.

Durch die zangenartige Ausbildung lässt sich eine Anpassung an verschiedene Grössen der Längsprofile erzielen.The pincer-like training allows an adaptation to different Achieve sizes of the longitudinal profiles.

Der Handgriff bietet sich für die Zuleitung der elektrischen Energie, des allfällig erforderlichen Kühlmittels und des gegebenenfalls vorhandenen Schutzgases an. Im übrigen kann der Handgriff als Träger für Hilfs- und Steueraggregate benutzt werden, wobei es ohne weiteres auch möglich ist, einen Teil dieser Aggregate im Gehäuse anzuordnen. Mittels solcher Hilfs- bzw Steueraggregate lässt sich eine Anpassung sowohl an verschiedene Materialien als auch an unterschiedliche Wandstärken erreichen. Die Anpassung an solche werkstückseitige Eigenschaften, zu welcher noch die Beschaffenheit des Anwendung findenden Lotes hinzukommt, kann mittels Einschaltdauer der Infrarotstrahler und zugeführter Betriebsspannung erfolgen. Hinsichtlich der Betriebsspannung wird vorzugsweise bei einer als Handgerät gebauten Vorrichtung mit Niederspannung von beispielsweise 50 Volt oder weniger gearbeitet. Nachdem es sich bei den Hilfs- und Steueraggregaten, welchen unter Umständen noch ein Sensor zur Temperaturmessung vorgeschaltet ist, um relativ aufwendige Apparaturen handelt, besteht die Möglichkeit, den Handgriff über eine Art Steckverbindung mit dem Gehäuse, welches den eigentlichen Träger für die Infrarotstrahler bildet, zu verbinden. Dadurch lässt sich eine Anpassung für unterschiedliche Anwendungsfälle, hervorgerufen durch unterschiedliche Profilformen bis hin zu flächenhaften Teilen, erzielen.The handle is ideal for the supply of electrical energy, any coolant required and any protective gas that may be present at. In addition, the handle can be used as a carrier for auxiliary and control units be, and it is easily possible to use some of these aggregates in the To arrange housing. An adjustment can be made by means of such auxiliary or control units on different materials as well as on different wall thicknesses. The adaptation to such workpiece-side properties, to which the condition of the solder that is used is added, the infrared heater can be switched on and supplied operating voltage. With regard to the operating voltage preferably with a device built as a hand-held device with low voltage of for example 50 volts or less worked. After the auxiliary and Control units, which may also have a sensor for temperature measurement is upstream, involves relatively complex equipment, there is the possibility of the Handle via a kind of plug connection with the housing, which is the actual Forms carrier for the infrared heater to connect. This allows an adjustment for different applications, caused by different profile shapes up to flat parts.

Die Erfindung soll nunmehr anhand von sie beispielsweise wiedergebenden Zeichnungen näher erläutert werden, und zwar zeigen: Fig. 1 eine perspektivische Ansicht der erfindungsgemässen Vorrichtung mit eingeführtem rohrförmigem Werkstück, Fig. 2 einen Querschnitt durch die Vorrichtung gemäss Fig. 1 ohne Werkstück.The invention is now intended to reproduce, for example, on the basis of it Drawings are explained in more detail, namely show: Fig. 1 is a perspective View of the device according to the invention with the tubular workpiece inserted, FIG. 2 shows a cross section through the device according to FIG. 1 without a workpiece.

Wie die beiden Figuren zeigen, besteht die Vorrichtung im wesentlichen aus Gehäuse 1 und Handgriff 2. Insbesondere aus Fig. 2 sind beispielhaft sechs innerhalb des Gehäuses 1 angeordnete Infrarotstrahler 3 ersichtlich. Wie symbolisch dargestellt, bestehen die Infrarotstrahler 3 aus Heizwendel 4 und Quarzrohr 5, wobei das Quarzrohr 5 mit einem Reflektor 6 versehen ist. Die Infrarotstrahler 3 umgeben das zu erwärmende Werkstück, welches im vorliegenden Falle, wie Fig. 1 beispielhaft zeigt, ein Rohr 7 darstellt. Die Infrarotstrahler 3 sind gegenüber dem Rohr 7, dh gegenüber der Löt- bzw Schweissstelle, durch ein Schutzglas 8 abgeschirmt. An der dem Schutzglas 8 gegenüberliegenden Seite sind die Infrarotstrahler 3 von einem Hilfsreflektor 9 umgeben.As the two figures show, the device consists essentially from housing 1 and handle 2. In particular from FIG. 2, six are exemplified within of the housing 1 arranged infrared radiator 3 can be seen. As symbolized, the infrared heater 3 consist of heating coil 4 and quartz tube 5, the quartz tube 5 is provided with a reflector 6. The infrared radiators 3 surround the to be heated Workpiece, which in the present case, as FIG. 1 shows by way of example, is a pipe 7 represents. The infrared radiators 3 are opposite the pipe 7, ie opposite the Soldering or welding point, shielded by a protective glass 8. On the protective glass 8 opposite side are the infrared radiators 3 from an auxiliary reflector 9 surrounded.

Die gemäss den Figuren beispielhaft dargestellte Vorrichtung ist mit einer Kühleinrichtung versehen und lässt sich darüberhinaus unter Verwendung eines Schutzgases betreiben. Die Kühleinrichtung ist im vorliegenden Falle als mantelförmiger Raum 10 ausgebildet, welcher den Hilfsreflektor 9 rückseitig umgibt. Zum Zu- und Abführen des Kühlmittels sind Stutzen 11, 12 vorgesehen. An diese Stutzen 11, 12 lassen sich die Zu- bzw Ableitungen für das Kühlmittel, welches aus Luft, Gas, Wasser oder dergleichen bestehen kann, anschliessen. Wie in Fig. 2 nicht detailliert dargestellt, ist der Kühlraum 10 stirnseitig so ausgebildet, dass auch die Anschlussstellen der Infrarotstrahler 3 ausreichend gekühlt werden.The device shown as an example according to the figures is with a cooling device and can also be used using a Operate protective gas. The cooling device is in the present case as a jacket-shaped Space 10 is formed, which surrounds the auxiliary reflector 9 on the rear. For access and Sockets 11, 12 are provided for discharging the coolant. To these nozzles 11, 12 the supply and discharge lines for the coolant, which consists of air, gas, water or the like may exist, connect. As not shown in detail in Fig. 2, the cooling space 10 is formed on the front side so that the connection points of the Infrared heater 3 are sufficiently cooled.

Zur Zuführung des Schutzgases auf die Löt- bzw Schweissstelle sind gemäss Fig. 2 sechs Austrittsöffnungen 13 vorgesehen. Diese Austrittsöffnungen 13 stehen mit einem Ringkanal 14 in Verbindung, welchem mittels eines am Handgriff angeordneten Schlauches 15 das Schutzgas über die Kanäle 16 zugeführt wird.To supply the protective gas to the soldering or welding point are According to FIG. 2, six outlet openings 13 are provided. These outlet openings 13 are in connection with an annular channel 14, which by means of an on the handle arranged hose 15, the protective gas is supplied via the channels 16.

Das verbrauchte Schutzgas kann stirnseitig entlang dem Werkstück 7 austreten, wo aus Gründen der Toleranz und Formgebung praktisch immer ein Zwischenraum vorhanden ist. Während sich aus diesen Gründen, insbesondere bei der Verwendung von Abdeckblechen, ein Zwischenraum ergibt, ist ein solcher bei Anordnung einer der Abschattung dienenden Bürste 17, wie diese gemäss den Figuren dargestellt ist, aus Gründen der Durchlässigkeit nicht erforderlich.The used shielding gas can be directed along the front side of the workpiece 7 emerge where, for reasons of tolerance and shape, there is practically always a gap is available. While for these reasons, especially when using of cover plates, there is a gap, is such when a the shadowing brush 17, as shown in the figures, not necessary for reasons of permeability.

Der Handgriff 2 dient ferner der Aufnahme wenigstens eines Teiles der Hilfs- und Steueraggregate. Zu diesem Zwecke mündet auch die elektrische Zuleitung 18 in den Handgriff 2. Den beispielhaft vorgesehenen Drehknöpfen 19, 20 kann beispielsweise die Spannungs-und Zeitwahl zugeordnet sein. Da diese Werte vom Material des Werkstückes, vom verwendeten Lot, von der Wandstärke des Werkstückes und dergleichen abhängig sind, können die einzustellenden Grössen mit solchen Werten kombiniert werden, so dass sich die Bedienungsperson um allzu theoretische und technische Einzelheiten nicht mehr kümmern muss.The handle 2 also serves to hold at least one part the auxiliary and control units. For this purpose, the electrical supply line also opens 18 in the handle 2. The rotary knobs 19, 20 provided by way of example can, for example the voltage and time selection must be assigned. Since these values depend on the material of the workpiece, on the solder used, on the wall thickness of the workpiece and the like the values to be set can be combined with such values, see above that the operator is concerned with overly theoretical and technical details no longer have to worry.

Wie Fig. 1 zeigt, ist das Gehäuse 1 zweiteilig ausgebildet. Die zweiteilige Ausführungsform kann insbesondere die Montagefreundlichkeit verbessern. Ausserdem kann die Zweiteiligkeit des Gehäuses auch derart ausgeführt sein, dass beispielsweise über Scharniere zwei voneinander unabhängige Gehäuseschalen zangenartig weg- und zugeschwenkt werden können. Durch eine solche zangenartige Ausbildung des Gehäuses kann der Aufnahmeraum für das Werkstück innerhalb grösserer Abmessungen variiert werden, so dass mit ein und derselben Vorrichtung Längsprofile unterschiedlichster Abmessungen bearbeitbar sind.As FIG. 1 shows, the housing 1 is constructed in two parts. The two-part Embodiment can in particular improve the ease of assembly. Besides that The two-part structure of the housing can also be designed such that, for example Two independent housing shells are hinge-like away and away like pliers can be swiveled shut. Such a pliers-like design of the housing the receiving space for the workpiece can vary within larger dimensions so that one and the same device can produce a wide variety of longitudinal profiles Dimensions are editable.
