Description
Beweglicher Füllaufsatz für Blankglühöfen, dessen Haube den Glühraum abschließt und das Glühgut vor und nach dem Glühen aufnimmt Es sind Vorrichtungen zum Blankglühen von Metallteilen bekannt, bei denen der Glühraum durch eine bewegliche Schutzglocke abgeschlossen wird, die das Glühgut vor und nach dem Glühen aufnimmt, und. unter ider es auf Wagen befördert werden kann. Hierbei wird -der Glühwagen mit dem Glühgut in den Glühraum eingebracht und verläßt .ihn wieder reit diesem. Dies hat den Nachteil, daß einerseits die hohe Glühtemperatur ihre zerstörende Wirkung auf den Wagen ausübt, andererseits für den kontinuierlichen Betrieb eine größere Anzahl von Wagen erforderlich ist.Movable filling attachment for bright annealing furnaces, the hood of which houses the annealing chamber closes and the material to be annealed takes up before and after the annealing There are devices Known for bright annealing of metal parts, in which the annealing chamber is movable Protective bell is closed, which takes up the material to be annealed before and after annealing, and. under which it can be transported on trolleys. Here the annealing car is used brought with the glowing material into the glowing room and leaves .ihn rides this again. This has the disadvantage that, on the one hand, the high annealing temperature has its destructive effect exerts on the car, on the other hand a larger one for continuous operation Number of trolleys is required.
Gemäß der Erfindung wird dieser Nachteil dadurch beseitigt, daß der Baden des Füllaufsatzes, der das Glühgut und die Schutzglocke trägt, aus einem mit Füßen versehenen Gestell besteht. Das beladene Gestell wird mittels eines an sich bekannten Hubwagens an den Glühofen herangefahren, über dem Glühraum abgesetzt, in an sich ebenfalls bekannter Weise in den Glühraum gesenkt, dann wieder gehoben, von dem Hubwagen unterfahren und weiterbefördert.According to the invention, this disadvantage is eliminated in that the Bathing the filling attachment, which carries the annealing material and the protective bell, from one with Feet provided frame consists. The loaded frame is by means of a per se known lift truck to the annealing furnace, placed above the annealing room, lowered into the glow chamber in a manner known per se, then raised again, underrun by the pallet truck and transported further.
In :den Abbildungen ist ein Ausführungsbeispiel dargestellt, bei welchem der engentliche Erfindungsgegenstand, nämlich das mit Füßen versehene Traggestell 17 für das Glühgut, bei sonst an sich bekannten Maßnahmen Verwendung findet. Der Glühraum z r liegt unter dem Boden :der Gießerei oder Hütte. Er wird durch die elektrischen Heizkörper 12 .erwärmt. In ihm sind als Glühgut beispielsweise Drahtbündel 13 auf dem durchbohrten Konus 1q. zentrisch gelagert. Der Konus 14 sitzt auf einer ebenfalls durchbohrten Platte 15, die ringsherum eine mit Sand gefüllte Ringnut 16 trägt. Das Ganze wird von einem von dem Hubwagen unterfahrbaren Gestell 17 getragen. Unter diesem befindet sich eine Plattform 18, die mit den Stäben z g verbunden .ist und außen eine weitere ringförmige mit Sand gefüllte Nut 2o besitzt. Die Plattform 18 kann durch hydraulischen Druck gehoben werden. Dabei greift die Stange 21, die an .der Decke der Schutzglocke 22 befestigt ist, in die entsprechende Bohrung des Konus i¢ ein. Dieser schiebt sich an ihr hinaus, bis er in die Platte 23 stößt und diese dann auch mit hochhebt. Der damit geöffnete obere Raum kann mittels der verschließbaren Gasleitung 24 mit Schutzgas angefüllt werden. Das auf dem Gestell lagernde geglühte Gut schiebt sich in die Schutzglocke ,ein, bis der obere Raum durch den Eingriff der Ringkante 26 in die mit Sand gefüllte Ringnut 16 abgeschlossen ist. Dabei wird auch die Schutzglocke 22 angehoben und aus ihrer Ringdichtung 31 gelöst. Sie kann nun mit ihrem Inhalt mittels des unter das Gestell 17 geführten Hubwagens 32 von der Plattform fortgeführt werden.In: the figures an embodiment is shown in which the narrow subject of the invention, namely the support frame 17 provided with feet for the annealing material, is used with measures that are otherwise known per se. The glow space zr is under the floor: the foundry or smelter. It is heated by the electric heating element 12. In it are, for example, wire bundles 13 on the pierced cone 1q as annealing material. centrally stored. The cone 14 sits on a plate 15, which is also drilled through and which has an annular groove 16 filled with sand around it. The whole is carried by a frame 17 that can be driven under by the lift truck. Below this is a platform 18 which is connected to the rods z g and has a further ring-shaped groove 2o filled with sand on the outside. The platform 18 can be raised by hydraulic pressure. The rod 21, which is attached to the cover of the protective bell 22, engages in the corresponding bore of the cone i [. This pushes itself out until it hits the plate 23 and then also lifts it up. The upper space thus opened can be filled with protective gas by means of the closable gas line 24. The annealed material stored on the frame is pushed into the protective bell until the upper space is closed by the engagement of the annular edge 26 in the annular groove 16 filled with sand. In the process, the protective bell 22 is also raised and released from its ring seal 31. It can now be continued from the platform with its contents by means of the lift truck 32 guided under the frame 17.
