It is an object of the invention to provide a holding device for a heating element and a heater with such a holding device, which is inexpensive to produce and stable in use.

Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 bzw. 9 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.This object is achieved with the features of claim 1 and 9, respectively. Advantageous embodiments are the subject of the dependent claims.

Gemäß Anspruch 1 wird eine Haltevorrichtung für ein Heizelement bereitgestellt, beispielsweise zur Verwendung in einem Wolfram Heizer. Die Haltevorrichtung ist aus einem Refraktärmetall oder aus einer Legierung auf Refraktärmetallbasis hergestellt, so dass sie hohen Temperaturen standhält bzw. auch bei hohen Temperaturen formbeständig bleibt. Mit einem Refraktärmetall oder einer Legierung auf Refraktärmetallbasis wird auf Metalle oder Legierungen Bezug genommen, die einen Schmelzpunkt größer gleich 1772°C (entspricht dem Schmelzpunkt von Platin) aufweisen. Die Haltevorrichtung weist zumindest zwei Halteelemente auf, die senkrecht oder im Wesentlichen senkrecht zueinander angeordnet sind. Beispielsweise ist an einem Halteelement ein Heizelement in Form eines Netzes oder Geflechts befestigbar bzw. gehalten, und mittels dem weiteren Halteelement, ist die Haltevorrichtung (mit dem Heizelement) in einem Ofenraum befestigbar. D.h. mittels der Haltevorrichtung kann ein Heizelement in einem Ofenraum gehalten bzw. befestigt werden. Die beiden Halteelemente sind miteinander verbunden, wobei eines der beiden Halteelemente eine Öffnung oder ein (durchgehendes) Loch, aufweist in dem zumindest ein Teil des anderen Halteelements angeordnet bzw. eingesteckt ist. Beispielsweise ist die Öffnung (vier)eckig oder rund, je nach Ausgestaltung des in die Öffnung eingeschobenen Teils des Halteelements. So wird am Ort der mechanischen Beanspruchung (d.h. am Ort der Verbindung der beiden Halteelemente) eine einfache und stabile Verbindung bereitgestellt. Insbesondere kann z.B. anstelle von mechanisch weniger stabilen abgekanteten Blechen, wie oben bzgl. CN 2896172 Y beschrieben, Vollmaterial mit größeren Querschnitten verwendet werden, so dass eine stabile Haltevorrichtung breitgestellt wird, die einfach und schnell herstellbar ist. Erfindungsmäßig ist ein erstes Halteelement zumindest teilweise in einer Öffnung eines zweiten Halteelements angeordnet, wobei das erste Halteelement mit dem zweiten Halteelement mittels Umformung verbunden ist. D.h. die beiden Halteelemente werden bei einer Temperatur deutlich unterhalb der Rekristallisationstemperatur miteinander verbunden. In einem beispielhaften Herstellungsverfahren wird das erste Halteelement in die Öffnung des zweiten Halteelements eingesteckt, so dass es auf der gegenüberliegenden Seite des zweiten Halteelements herausragt. In einem anschließenden Schritt wird der herausragende Teil z.B. durch Taumeln kaltumgeformt, so dass die beiden Halteelemente sicher miteinander verbunden werden.According to claim 1, a holding device for a heating element is provided, for example for use in a tungsten heater. The holding device is made of a refractory metal or an alloy based on refractory metal, so that it withstands high temperatures or remains dimensionally stable even at high temperatures. Reference is made to metals or alloys having a refractory metal or a refractory metal alloy which has a melting point greater than or equal to 1772 ° C (equivalent to the melting point of platinum). The holding device has at least two holding elements, which are arranged perpendicular or substantially perpendicular to each other. For example, a heating element in the form of a network or braid can be fastened or held on a holding element, and by means of the further holding element, the holding device (with the heating element) in a furnace chamber fixable. That is, by means of the holding device, a heating element can be held or fastened in a furnace chamber. The two holding elements are connected to one another, one of the two holding elements having an opening or a (through) hole, in which at least one part of the other holding element is arranged or inserted. For example, the opening (four) is angular or round, depending on the configuration of the inserted into the opening part of the holding element. Thus, a simple and stable connection is provided at the location of the mechanical stress (ie at the location of the connection of the two holding elements). In particular, for example, instead of mechanically less stable bent sheets, as above with respect. CN 2896172 Y described, solid material can be used with larger cross-sections, so that a stable holding device is provided, which is easy and quick to produce. According to the invention, a first holding element is arranged at least partially in an opening of a second holding element, wherein the first holding element is connected to the second holding element by means of deformation. That is, the two holding elements are connected together at a temperature well below the recrystallization temperature. In an exemplary manufacturing method, the first holding element is inserted into the opening of the second holding element, so that it protrudes on the opposite side of the second holding element. In a subsequent step, the protruding part is cold-formed, for example by tumbling, so that the two holding elements are securely connected to one another.

Durch Schweißen bzw. durch die hohen lokalen Temperaturen während eines Schweißvorgangs können am Ort der Schweißnaht Mikrorisse und Gefügeversprödungen auftreten. Um dies zu verhindern, sind besonders bevorzugt das erste und das zweite Halteelement nicht miteinander verschweißt.By welding or by the high local temperatures during a welding process, microcracks and microstructural brittleness can occur at the site of the weld. In order to prevent this, particularly preferably the first and the second holding element are not welded together.

Gemäß einer Ausgestaltung ist die Haltevorrichtung stromleitend, so dass sie zusätzlich als Stromanschluss für ein an der Haltevorrichtung befestigbares Heizelement verwendet werden kann.According to one embodiment, the holding device is current-conducting, so that it can additionally be used as a power connection for a heating element which can be fastened to the holding device.

Vorzugsweise ist zumindest eines der Halteelemente einteilig ausgebildet bzw. aus einem Vollmaterial hergestellt, d.h. nicht aus einem Blech. Beispielsweise ist zumindest ein Halteelement als Stab, Vierkant- oder Mehrkantprofil ausgebildet. Dadurch wird die mechanische Stabilität der einzelnen Halteelemente und damit der Haltevorrichtung erhöht. Weiterhin wird die Herstellung der Halteelemente vereinfacht, da sie einfach und schnell z.B. durch Ablängen von Stangenware hergestellt werden können. Besonders bevorzugt sind beide Halteelemente aus einem Vollmaterial ausgebildet.Preferably, at least one of the holding elements is integrally formed or made of a solid material, i. not from a sheet. For example, at least one retaining element is designed as a rod, square or polygonal profile. As a result, the mechanical stability of the individual holding elements and thus of the holding device is increased. Furthermore, the manufacture of the holding elements is simplified because they are simple and fast, e.g. can be produced by cutting to length. Particularly preferably, both holding elements are formed from a solid material.

Besonders bevorzugt ist die Haltevorrichtung mit dem ersten Halteelement in einem Ofenraum befestigbar, z.B. mittels Schrauben oder einer Klemmverbindung zwischen dem ersten Halteelement und dem Ofenraum. D.h. wenn beispielsweise an der Haltevorrichtung (bzw. am zweiten Halteelement) ein Heizelement hängend befestigt ist, wie z.B. ein Wolframnetz oder -blech, dann hängt das ganze Gewicht der Haltevorrichtung und des Heizelements am ersten Halteelement. Alternativ ist ein Heizelement - z.B. in Form eines Blechs - stehend auf der Haltevorrichtung angeordnet, wobei das Gewicht der Haltevorrichtung und des Heizelements ebenfalls am ersten Halteelement angreift.Particularly preferably, the holding device with the first holding element in a furnace chamber can be fastened, e.g. by means of screws or a clamping connection between the first holding element and the furnace chamber. That For example, if a heating element is attached to the holding device (or the second holding element) in a suspended manner, such as e.g. a tungsten mesh or sheet, then the entire weight of the holding device and the heating element depends on the first holding element. Alternatively, a heating element - e.g. in the form of a sheet - standing arranged on the holding device, wherein the weight of the holding device and the heating element also acts on the first holding element.

Gemäß einer Ausgestaltung weist die Haltevorrichtung ein drittes Halteelement auf, das am zweiten Halteelement befestigt ist, d.h. bei Verwendung der Haltevorrichtung ist ein Heizelement wie z.B. ein Wolfram-Netz am dritten Halteelement befestigt, beispielsweise mit dem dritten Halteelement verschweißt. Durch die Verwendung eines dritten Halteelements, dessen Abmessungen an das jeweils verwendete Heizungselement angepasst ist, kann das erste und zweite Halteelement unabhängig von den Abmessungen des verwendeten Heizungselements hergestellt werden. D.h. nach dem 'Baukastenprinzip' können in einem Herstellungsschritt eine Vielzahl von identischen Einheiten bestehend aus dem ersten und zweiten Halteelement hergestellt werden, die anschließend durch das Befestigen des entsprechend dimensionierten bzw. ausgestalteten dritten Halteelements an die entsprechende Anwendung bzw. an das entsprechende Heizungselement angepasst werden können. Beispielsweise kann das dritte Halteelement an einen zylindrischen oder eckigen Ofenraum bzw. Heizer angepasst werden, d.h. das dritte Halteelement kann gebogen oder gerade ausgebildet sein oder jede andere beliebige Form aufweisen, die an die jeweilige Anwendung angepasst ist.According to one embodiment, the holding device has a third holding element which is fastened to the second holding element, ie when using the holding device, a heating element such as a tungsten mesh is attached to the third holding element, for example, welded to the third holding element. By using a third holding element whose dimensions are adapted to the heating element used in each case, the first and second holding element can be produced independently of the dimensions of the heating element used. That is, according to the 'modular principle' can be made in a manufacturing step, a plurality of identical units consisting of the first and second holding element, which are then adapted by attaching the appropriately dimensioned or designed third holding element to the appropriate application or to the corresponding heating element can. For example, the third holding element can be adapted to a cylindrical or angular oven space or heater, ie the third holding element can be bent or straight or have any other desired shape, which is adapted to the particular application.

Vorzugsweise sind das zweite und dritte Halteelement mittels zumindest einem formschlüssigen und/oder kraftschlüssigen Verbindungsmittel miteinander verbunden, beispielsweise mittels Nieten oder Schrauben. Besonders bevorzugt sind das zweite und dritte Halteelement nicht stoffschlüssig miteinander verbunden, beispielsweise nicht miteinander verschweißt. D.h. durch eine Verbindung z.B. mittels Nieten werden die oben beschriebenen Nachteile des Schweißens umgangen.Preferably, the second and third retaining element are connected to each other by means of at least one positive and / or non-positive connection means, for example by means of rivets or screws. Particularly preferably, the second and third retaining element are not materially connected to each other, for example, not welded together. That through a connection e.g. By means of riveting, the above-described disadvantages of welding are avoided.

Besonders bevorzugt ist die Haltevorrichtung bzw. das erste, zweite und dritte Halteelement aus Wolfram oder einer Wolfram-basierten Legierung gebildet. Eine Wolfram-basierte Legierung ist eine Legierung mit einem Anteil von ≥ 50 Gew.% Wolfram. Vorzugsweise weist die Wolfram-basierte Legierung einen Wolfram-Anteil von ≥ 90 Gew.% auf. Die wie oben beschriebene Verbindung der Haltelemente ist in dieser Ausgestaltung besonders vorteilhaft, da Wolfram zur Versprödung neigt und damit mittels herkömmlichen Verbindungstechnologien (wie z.B. Schweißen) nur schwer zu verbinden ist.Particularly preferably, the holding device or the first, second and third holding element is formed from tungsten or a tungsten-based alloy. A tungsten-based alloy is an alloy containing ≥ 50 wt% tungsten. Preferably, the tungsten-based alloy has a tungsten content of ≥ 90% by weight. The connection of the holding elements as described above is particularly advantageous in this embodiment, since tungsten is prone to embrittlement and thus difficult to connect by conventional joining technologies (such as welding).

Gemäß Anspruch 11 wird ein Heizer bereitgestellt, beispielsweise ein Wolfram-Heizer, mit zumindest einer wie oben und im folgenden beschriebenen Haltevorrichtung, wobei die zumindest eine Haltevorrichtung mit zumindest einem Heizelement stromleitend verbunden ist.According to claim 11, a heater is provided, for example a tungsten heater, with at least one holding device as described above and below, wherein the at least one holding device is electrically conductively connected to at least one heating element.

Einzelne Merkmale der oben beschrieben Ausgestaltungen der Haltevorrichtung sowie des Heizers und einzelne Merkmale der im folgenden Ausführungsbeispiel beschriebenen Haltevorrichtung können auf beliebige Weise miteinander kombiniert werden.Individual features of the above-described embodiments of the holding device and the heater and individual features of the holding device described in the following embodiment can be combined with each other in any way.

Anhand der Figuren wird eine Ausführungsform der Erfindung näher erläutert.With reference to the figures, an embodiment of the invention will be explained in more detail.

Fig. 1a-b zeigen Perspektivansichten einer Haltevorrichtung 2 gemäß einer bevorzugten Ausgestaltung. Die Haltevorrichtung 2 wird aus einem ersten, zweiten und dritten Halteelement 4, 6, 8 gebildet, die miteinander verbunden sind und aus einem Refraktärmetall bzw. aus einer Legierung auf Refraktärmetallbasis hergestellt sind, z.B. Wolfram oder Molybdän. Die Haltevorrichtung 2 ist stromleitend und wird zur Stromversorgung eines (oder mehrerer) Heizelemente 18 verwendet, die an der Haltevorrichtung 2 (hängend) befestigt werden können. Das in Fig. 1a skizzenhaft dargestellte Heizelement 18 ist beispielsweise aus einem Wolfram-Netz, einem Blech oder einer Vielzahl von (vertikal verlaufenden) Drähten ausgebildet. Fig. 1a-b show perspective views of a holding device 2 according to a preferred embodiment. The holding device 2 is formed from a first, second and third holding element 4, 6, 8, which are connected to each other and made of a refractory metal or on a refractory metal-based alloy, for example tungsten or molybdenum. The holding device 2 is electrically conductive and is used to power one (or more) heating elements 18, which can be attached to the holding device 2 (hanging). This in Fig. 1a sketched illustrated heating element 18 is formed for example of a tungsten mesh, a sheet or a plurality of (vertical) wires.

Bei der Verwendung der Haltevorrichtung 2 ist die Haltevorrichtung in einem Ofenraum (nicht dargestellt) befestigt, durch Befestigen des ersten Halteelements 4 bzw. des Trägers beispielsweise mittels einer Klemmverbindung oder mittels Schrauben im Ofenraum. D.h. nach der Montage ist die Haltevorrichtung 2 bzw. das Heizelement 18 hängend (am ersten Halteelement 4) im Ofenraum angeordnet. Am dritten Halteelement 8 wird das Heizelement 18 beispielsweise mittels einer Klemmverbindung und/oder Schweißverbindung befestigt, um einen guten elektrischen Kontakt zu gewährleisten.When using the holding device 2, the holding device in a furnace chamber (not shown) attached by attaching the first holding member 4 and the support, for example by means of a clamp connection or by means of screws in the furnace chamber. That After mounting, the holding device 2 or the heating element 18 is arranged hanging (on the first holding element 4) in the oven chamber. On the third holding element 8, the heating element 18 is fastened, for example, by means of a clamping connection and / or welded connection in order to ensure good electrical contact.

Fig. 2 zeigt eine Explosionsansicht der Haltevorrichtung 2 von Fig. 1, um die Verbindung der drei Halteelemente 4, 6, 8 darzustellen. Die Halteelemente 4, 6, 8 sind aus Vollmaterial hergestellt bzw. sind nicht durch Abkanten von Blechen hergestellt. Das erste Halteelement 4 weist an einem Ende einen Zapfen 12 auf, der in eine entsprechend ausgebildete Öffnung 10 des zweiten Halteelements 6 eingesteckt wird. Anschließend wird der Zapfen 12 mittels Kaltumformung, wie z.B. Taumeln, umgeformt, so dass das erste und zweite Halteelement 4, 6 sicher miteinander verbunden sind. Fig. 2 shows an exploded view of the holding device 2 of Fig. 1 to illustrate the connection of the three holding elements 4, 6, 8. The holding elements 4, 6, 8 are made of solid material or are not produced by bending of sheets. The first holding element 4 has at one end a pin 12 which is inserted into a correspondingly formed opening 10 of the second holding element 6. Subsequently, the pin 12 by means of cold forming, such as tumbling, reshaped, so that the first and second holding element 4, 6 are securely connected to each other.

Nach der Verbindung des ersten und zweiten Halteelements 4, 6 wird das dritte Halteelement 8 mittels vier Nieten 16a-d mit dem zweiten Halteelement 6 verbunden.After the connection of the first and second holding elements 4, 6, the third holding element 8 is connected to the second holding element 6 by means of four rivets 16a-d.

D.h. in dieser Ausgestaltung der Haltevorrichtung 2 ist ein Verschweißen der einzelnen Elemente nicht notwendig, so dass die Nachteile des Schweißens (Mikrorissbildung, Gefügeversprödung) umgangen werden können.That is, in this embodiment of the holding device 2, a welding of the individual elements is not necessary, so that the disadvantages of welding (micro-cracking, microstructural embrittlement) can be avoided.

Am ersten Halteelement 4 können optional zwei Fasen 14a-b angeordnet werden, die nach dem Zusammenstecken benachbart zum zweiten Halteelement 6 liegen. Die Fasen 14a-b können eine Schweißnaht aufnehmen, um die Verbindung zwischen den beiden Halteelementen 4, 6 zusätzlich zu sichern, wobei der Ort der Schweißnaht außerhalb oder im Wesentlichen außerhalb des Orts der mechanischen Belastung bei der Verwendung der Haltevorrichtung liegt. D.h. die Schweißnaht bzw. -nähte sind ausreichend beabstandet zur Verbindung (Öffnung 10/ Zapfen 12) zwischen erstem und zweitem Halteelement, so dass das Schweißen keinen negativen Einfluss auf die Verbindung hat.On the first holding element 4, two bevels 14a-b can optionally be arranged, which are adjacent to the second holding element 6 after being plugged together. The chamfers 14a-b may receive a weld to further secure the connection between the two retaining elements 4, 6, where the location of the weld is outside or substantially outside the location of mechanical stress when using the fixture. That the weld or seams are sufficiently spaced from the connection (opening 10 / pin 12) between the first and second retaining elements so that the welding has no negative influence on the connection.

Fig. 3a-c zeigen Seitenansichten und ein Draufsicht der oben beschriebenen Haltevorrichtung 2. Die beispielhafte Haltevorrichtung 2 ist zur Verwendung in einem zylinderförmigen Ofenraum ausgebildet, insbesondere werden drei der abgebildeten Haltevorrichtungen 2 benötigt, um damit mittels der entsprechenden Heizelemente 18 einen zylinderförmigen Ofenraum zu beheizen. Dazu ist zumindest das dritte Halteelement 8 bzw. der Heizelementträger aus einem gebogenen Blech hergestellt, dessen Krümmung an die Abmessungen des Ofenraums angepasst ist. Fig. 3a-c The exemplary holding device 2 is designed for use in a cylindrical oven space, in particular three of the illustrated holding devices 2 are required in order to heat by means of the corresponding heating elements 18 a cylindrical oven space. For this purpose, at least the third holding element 8 or the Heizelementträger made of a bent sheet metal, whose curvature is adapted to the dimensions of the furnace chamber.

Ein Ofenraum kann einen beliebigen Querschnitt aufweisen, beispielsweise rechteckig, oval usw. Entsprechend kann das dritte Halteelement 8 an die verschiedenen Abmessungen des Ofenraums bzw. der Heizelemente angepasst werden. D.h. bei der Herstellung der Haltevorrichtung können zunächst Einheiten bestehend aus dem ersten und zweiten Halteelement beispielsweise auf Vorrat hergestellt werden. Erst mit der Befestigung des entsprechend dimensionierten dritten Halteelements wird die Haltevorrichtung an die entsprechende Abmessungen eines Ofenraums bzw. eines Heizelements angepasst, d.h. das dritte Halteelement weist beispielsweise eine bestimmte Krümmung und eine bestimmte Länge auf. Da das dritte Halteelement 8 auf einfache und schnelle Weise mittels Nieten 16a-d mit dem zweiten Halteelement 6 verbunden werden kann, können auf diese Weise nach dem 'Baukastenprinzip' Haltevorrichtungen 2 schnell und einfach an die jeweilige Anwendung angepasst werden.A furnace chamber can have any cross-section, for example rectangular, oval, etc. Correspondingly, the third retaining element 8 can be adapted to the different dimensions of the furnace chamber or of the heating elements. That is to say, in the production of the holding device, units consisting of the first and second holding element can first be produced, for example, in stock. Only with the attachment of the correspondingly dimensioned third holding element, the holding device is adapted to the corresponding dimensions of a furnace chamber or a heating element, ie, the third holding element has, for example, a certain curvature and a certain length. Since the third holding element 8 can be connected to the second holding element 6 in a simple and rapid manner by means of rivets 16a-d, holding devices 2 can be adapted quickly and easily to the respective application in this way according to the 'modular principle'.

Gemäß einer alternativen, hier nicht dargestellten Ausgestaltung ist die Haltevorrichtung nur aus einem ersten und zweiten Halteelement hergestellt, wobei das zweite Halteelement ausgebildet ist bzw. entsprechende Abmessungen aufweist, ein Heizelement 18 daran zu befestigen.According to an alternative, not shown embodiment, the holding device is made only of a first and second holding element, wherein the second holding element is formed or has corresponding dimensions, to attach a heating element 18 thereto.
