Description

Die Erfindung betrifft einen Glühkorb mit geschlossenem oder rostförmigen Boden, der an den Rändern einstückig angeformte aufragende Pfeiler aufweist, und mit einem auf den Pfeilern ruhenden Rahmen, der an den Pfeilern über dehnungsbewegliche Ösenverbindungen unverlierbar befestigt ist, wobei jede Ösenverbindung einen durch eine Öse hindurchragenden Zapfen aufweist, dessen Ende eine nicht durch die Öse hindurchpassende Verdickung trägt.The invention relates to a glow basket with a closed or rust-shaped bottom, which has upstanding pillars integrally formed on the edges, and with a frame resting on the pillars, which is captively attached to the pillars by means of flexible eyelet connections, each eyelet connection having a pin projecting through an eyelet has, the end of which carries a thickening not fitting through the eyelet.

Glühkörbezum Transport von Glühgut durch einen Glühofen und auch zum Abschrecken des Glühgutes in Abschreckungsflüssigkeit sind grossen Temperaturschwankungen und örtlichen Temperaturdifferenzen ausgesetzt, so dass sie grosse Wärmespannungen erleiden. Die grösste thermische Beanspruchung tritt an dem Rahmen auf, der die obere Randeinfassung des Glühkorbes bildet.Annealing baskets for the transport of annealing material through an annealing furnace and also for quenching the annealing material in quenching liquid are exposed to large temperature fluctuations and local temperature differences, so that they suffer high thermal stresses. The greatest thermal stress occurs on the frame that forms the upper rim of the glow basket.

Bei einem bekannten Glühkorb der eingangs genannten Art (DE-OS 2817718) ist der Boden zusammen mit den ihm angeformten aufragenden Pfeilern als einstückiges Gussteil hergestellt. In Nuten an den oberen Enden der Pfeiler ist der als separates Teil hergestellte Rahmen eingesetzt. Die Befestigung des Rahmens an den Pfeilern erfolgt mit Ösen oder Rähmchen, die nach unten hin von der Aussenseite des Rahmens abstehen und verdickte Köpfe der Pfeiler übergreifen. Bei der Herstellung des Rahmens werden für jede Öse nur zwei Stege gegossen. Der die Öse schliessende dritte Steg wird als Schlussglied später angeschweisst, nachdem der Rahmen auf die Enden der Pfeiler aufgesetzt worden ist. Dieses Anschweissen der Schlussglieder erfordert an jeder Öse zwei Schweissstellen und zusätzlich den Einsatz von Fremdmaterial für das Schlussglied. Dies ergibt einen hohen Aufwand an manueller Fertigungsarbeit und Herstellungskosten.In a known glow basket of the type mentioned at the outset (DE-OS 2817718), the base is made as a one-piece casting together with the upstanding pillars molded onto it. The frame, which is made as a separate part, is inserted into grooves at the upper ends of the pillars. The frame is fastened to the pillars with eyelets or frames that protrude downwards from the outside of the frame and overlap thickened heads of the pillars. In the manufacture of the frame, only two webs are cast for each eyelet. The third bridge closing the eyelet is later welded on as the final link after the frame has been placed on the ends of the pillars. This welding of the closing links requires two welding points on each eyelet and the use of foreign material for the closing link. This results in a high amount of manual manufacturing work and manufacturing costs.

Der Erfindung liegt die Aufgabe zugrunde, einen Glühkorb der eingangs genannten Art im Hinblick auf einfachere Fertigungsmöglichkeiten zu verbessern.The invention has for its object to improve a glow basket of the type mentioned with regard to simpler manufacturing options.

Die Lösung dieser Aufgabe besteht erfindungsgemäss darin, dass die Ösen den Pfeilern oder den Rahmen einstückig angegossen und horizontal ausgerichtet sind und dass die Verdickungen an den sich vertikal erstreckenden Zapfen angeschweisst sind.According to the invention, this object is achieved in that the eyelets are cast in one piece onto the pillars or the frame and are aligned horizontally and that the thickenings are welded to the vertically extending pin.

Bei dem erfindungsgemässen Glühkorb werden die Ösen nicht in einem späteren Fertigungsschritt durch ein Schlussglied vervollständigt, sondern sie werden beim Giessen des Bodens oder des Rahmens diesem Boden oder Rahmen vollständig angeformt. Bei der Montage des Rahmens an den Enden der Pfeiler des Bodens werden die vertikalen Zapfen in die horizontalen Ösen eingesteckt. Die Verriegelung erfolgt anschliessend durch Anschweissen der Verdickungen an den durch die Ösen hindurchragenden Enden der Zapfen. Hierbei ist für die Verriegelung jeder Ösenverbindung nur ein einziger Schweissvorgang erforderlich. Vorzugsweise bestehen die Verdickungen aus Schweisspunkten, wobei jeder Schweisspunkt durch Schweissmaterialauftrag erzeugt ist. Hierbei wird ausser dem Schweissmaterial kein zusätzliches Fremdmaterial benötigt. Die Schweisspunkte können auf einfache Weise durch gezieltes Ansetzen einer Schweisselektrode an die Zapfen hergestellt werden, wobei jedoch darauf zu achten ist, dass die Schweisspunkte einen Abstand von der Öse haben, damit diese nicht eingeklemmt wird und die Dehnungsbeweglichkeit der Ösenverbindung beibehalten wird.In the glow basket according to the invention, the eyelets are not completed by a closing member in a later production step, but they are completely molded onto this floor or frame when the floor or frame is cast. When mounting the frame on the ends of the pillars of the floor, the vertical pins are inserted into the horizontal eyelets. The locking then takes place by welding the thickened portions to the ends of the pins protruding through the eyelets. Only one welding process is required to lock each eyelet connection. The thickenings preferably consist of welding points, each welding point being produced by applying welding material. Apart from the welding material, no additional foreign material is required. The welding points can be easily produced by placing a welding electrode on the pins, but it must be ensured that the welding points are at a distance from the eyelet so that it is not pinched and the flexibility of the eyelet connection is maintained.

Vorzugsweise sind die Ösen dem Rahmen angeformt und die Pfeiler weisen an ihren Innenseiten horizontale Standflächen für den Rahmen auf. Die Standflächen, die zum Innern des Glühkorbs nicht durch aufragende Teile begrenzt sind, erlauben Bewegungen des Rahmens in bezug auf den Boden bzw. die Pfeiler. Ausserdem wird erreicht, dass die Innenseite des Rahmens weitgehend bündig ist mit den inneren Begrenzungen der Pfeiler, so dass ein in den Glühkorb eingesetztes Drahtgitter am Übergang zwischen Pfeilern und Rahmen nicht verbogen wird.The eyelets are preferably molded onto the frame and the pillars have horizontal standing surfaces for the frame on their inner sides. The standing surfaces, which are not delimited by protruding parts on the inside of the glow basket, allow movements of the frame with respect to the floor or the pillars. It is also achieved that the inside of the frame is largely flush with the inner boundaries of the pillars, so that a wire mesh inserted in the glow basket is not bent at the transition between pillars and frame.

Der obere Rahmen kann einstückig hergestellt werden, besteht jedoch zweckmässigerweise aus separaten Rahmenleisten. Wenn der Rahmen aus separaten Leisten besteht, können sich diese Rahmenleisten unabhängig voneinander ausdehnen und bewegen. Ausserdem lassen sich die Rahmenleisten in separaten Giessformen einfacher herstellen als ein einstückiger Rahmen.The upper frame can be made in one piece, but expediently consists of separate frame strips. If the frame consists of separate strips, these frame strips can expand and move independently of one another. In addition, the moldings in separate molds are easier to manufacture than a one-piece frame.

Gemäss einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass die Pfeiler an den Ecken des Bodens jeweils durch zwei Ösen der beiden angrenzenden Rahmenleisten hindurchragen und dass die beiden Ösen in unterschiedlichen Höhen angeordnet sind. Hierdurch ergibt sich, bei einem mehrteiligen Rahmen eine einfache Gestaltung der Eckverbindungen.According to a preferred development of the invention, it is provided that the pillars at the corners of the floor each protrude through two eyelets of the two adjacent frame strips and that the two eyelets are arranged at different heights. This results in a simple design of the corner connections in a multi-part frame.

Der erfindungsgemässe Glühkorb hat nicht nur den Vorteil eines einfachen konstruktiven Aufbaus, sondern er ist auch stapelbar und auf dem Ofenboden verschiebbar. Die Ösenverbindungen liefern das in allen Richtungen erforderliche Spiel bzw. die Dehnungsbeweglichkeit zwischen Boden und Rahmen.The glow basket according to the invention not only has the advantage of a simple construction, but it is also stackable and slidable on the furnace floor. The eyelet connections provide the play required in all directions and the flexibility between the floor and frame.

Im folgenden werden unter Bezugnahme auf die Zeichnungen Ausführungsbeispiele der Erfindung näher erläutert.Exemplary embodiments of the invention are explained in more detail below with reference to the drawings.

Der dargestellte Glühkorb weist einen Boden 10 und einen oberen Rahmen 11 auf. Der Boden 10 besteht aus einem einstückigen Teil aus einem ebenen Bodehrost 12 aus einander kreuzenden Gitterstäben und am Rand des Bodenrostes aufragenden senkrechten Pfeilern 13, die jeweils in die Gitterstäbe des Bodenrostes übergehen. Jeder Pfeiler 13 weist an seiner Innenseite eine horizontale Aufstandfläche 14 auf, die nach aussen durch einen aufragenden Zapfen 15 begrenzt ist und zum Innern des Glühkorbs in frei ausläuft, d.h. nicht durch aufragende Teile begrenzt ist.The glow basket shown has a bottom 10 and an upper frame 11. The floor 10 consists of a one-piece part from a flat floor grate 12 made of cross-bars and up on the edge of the floor grate Genden vertical pillars 13, each of which merge into the bars of the floor grate. Each pillar 13 has on its inside a horizontal contact surface 14, which is delimited on the outside by a protruding pin 15 and runs out to the inside of the glow basket, ie is not delimited by protruding parts.

Auf die Standflächen 14 der Pfeiler 13 wird der obere Rahmen 11 gestellt. Dieser Rahmen ist, ebenso wie der Boden 10, rechteckig und er besteht aus den beiden längslaufenden Rahmenleisten 16 und den beiden querlaufenden Rahmenleisten 17. Diese Rahmenleisten 16 und 17 sind separate Gussteile. Jede der Rahmenleisten besteht aus einem hochkant stehenden Streifen, an dem aussen in der Nähe der Unterkante zahlreiche Ösen 18 abstehen. Die Ösen 18 verlaufen horizontal, d.h. sie haben vertikale Durchtrittsöffnungen. Die rechteckigen Ösen 18 sind an einer Seite durch den Streifen der jeweiligen Rahmenleiste 16 bzw. 17 begrenzt und an den drei anderen Seiten durch die U-förmig angeordneten Ösenstege. Die Höhe einer jeden Öse beträgt etwa die Hälfte der Höhe des Streifens der Rahmenleiste.The upper frame 11 is placed on the standing surfaces 14 of the pillars 13. This frame, like the floor 10, is rectangular and it consists of the two longitudinal frame bars 16 and the two transverse frame bars 17. These frame bars 16 and 17 are separate castings. Each of the frame strips consists of an upright strip, on the outside of which numerous eyelets 18 project near the lower edge. The eyelets 18 run horizontally, i.e. they have vertical openings. The rectangular eyelets 18 are delimited on one side by the strip of the respective frame strip 16 and 17 and on the three other sides by the U-shaped eyelet webs. The height of each eyelet is approximately half the height of the frame strip.

Die querlaufenden Rahmenleisten 17 haben jeweils zwei angeformte Handgriffe 19.The transverse frame strips 17 each have two molded handles 19.

Wie Fig. 2 zeigt, steht jede Rahmenleiste 17 mit ihrer Unterseite auf den horizontalen Standflächen 14 der Pfeiler 13, wobei die Innenseiten der Pfeiler 13 mit der Innenseite der Rahmenleiste 16 bzw. 17 fluchten. Dies bedeutet, dass die Stärke der Rahmenleiste 17 annähernd der Breite der Standfläche 14 entspricht. Das Loch 20 der Öse 18 hat Übermass gegenüber dem Querschnitt des Zapfens 15, der das obere Ende des Pfeilers 1 3 bildet. Der Zapfen 15 ragt durch das Loch 20 hindurch. Da die Höhe des Zapfens 15 etwa gleich der Höhe der Rahmenleiste 17 ist, schliesst die Oberseite des Zapfens 15 bündig mit der Rahmenleiste 17 ab.As shown in FIG. 2, the underside of each frame bar 17 stands on the horizontal standing surfaces 14 of the pillars 13, the inside of the pillars 13 being flush with the inside of the frame bar 16 and 17, respectively. This means that the thickness of the frame strip 17 corresponds approximately to the width of the footprint 14. The hole 20 of the eyelet 18 is oversized compared to the cross section of the pin 15, which forms the upper end of the pillar 13. The pin 15 protrudes through the hole 20. Since the height of the pin 15 is approximately equal to the height of the frame bar 17, the top of the pin 15 is flush with the frame bar 17.

Zur Verhinderung des Entfernens der Rahmenleiste 17 von dem Pfeiler 13 ist an dem aus der Öse 18 herausragenden Bereich des Zapfens 15 eine Verdickung 21 in Form eines Schweisspunktes angebracht. Die Verdickung 21 hat einen Abstand a von der Oberseite der Öse 18, um die erforderliche Dehnungsbeweglichkeit sicherzustellen. Bei der Erzeugung des Schweisspunktes 21 kann ein Abstandsstreifen auf die Oberseite der Öse 18 gelegt werden, um den Abstand a einzuhalten. Der Abstandsstreifen wird anschliessend wieder entfernt.To prevent removal of the frame strip 17 from the pillar 13, a thickening 21 in the form of a welding spot is attached to the region of the pin 15 protruding from the eyelet 18. The thickening 21 has a distance a from the top of the eyelet 18 in order to ensure the required flexibility of expansion. When creating the welding point 21, a spacer strip can be placed on the top of the eyelet 18 in order to maintain the distance a. The spacer strip is then removed again.

Fig. 3 zeigt eine Eckverbindung des Rahmens 11 des Glühkorbs. An dem betreffenden Pfeiler 13' ist die Standfläche 14 tiefer angeordnet als bei den übrigen Pfeilern. An dem Ende der Rahmenleiste 16 ist eine nach unten gezogene Verlängerung vorgesehen, an der eine Öse 18' angeordnet ist, welche auf der Standfläche 14 aufliegt. Auf die Öse 18' ist die querlaufende Rahmenleiste 17 mit der Öse 18 aufgesetzt, wobei der Zapfen 15 durch beide Ösen 18 und 18' hindurchgeht.Fig. 3 shows a corner connection of the frame 11 of the glow basket. The standing surface 14 on the relevant pillar 13 'is arranged lower than in the other pillars. At the end of the frame bar 16, a downward extension is provided, on which an eyelet 18 'is arranged, which rests on the base 14. The transverse frame strip 17 with the eyelet 18 is placed on the eyelet 18 ', the pin 15 passing through both eyelets 18 and 18'.

Fig. 4zeigtein Ausführungsbeispiel, bei dem die Ösen 18 den Pfeilern 13 angeformt sind, während die Zapfen 15, die vertikal durch die Ösen 18 hindurchgehen, von der Rahmenleiste 17 nach unten abstehen. An dem aus der Öse 18 nach unten herausragenden Ende des Zapfens 15 befindet sich die nachträglich angebrachte Verdickung 21 in Form eines Schweisspunktes. Die Standfläche 14 befindet sich bei diesem Ausführungsbeispiel am oberen Ende des Pfeilers 13.Fig. 4 shows an embodiment in which the eyelets 18 are integrally formed on the pillars 13, while the pins 15, which pass vertically through the eyelets 18, project downwards from the frame strip 17. At the end of the pin 15 projecting downward from the eyelet 18 is the subsequently applied thickening 21 in the form of a welding spot. The standing surface 14 is in this embodiment at the upper end of the pillar 13.
