Description

Verfahren zum Fördern von Glühgut durch öfen mit zwei Gruppen beweglicher Tragbalken Es ist bekannt, bei ununterbrochen arbeitenden öfen die- Förderung .des Wärm- oder Glühgutes in der Weise vorzunehmen, daß die beweglichen Herdteile beispielsweise mittels Exzenter eine kreisförmige oder .mittels eines anderen bekannten Antriebes eire elliptische, rechteckige oder ähnlich geformte Bewegung ausführen und dadurch das Glühgut schrittweise durch dien Ofen bewegen.Method for conveying annealing material through furnaces with two groups of movable Supporting beam It is known to promote the .des in continuously operating ovens To make heat or incandescent material in such a way that the movable stove parts, for example by means of an eccentric a circular drive or by means of another known drive perform an elliptical, rectangular or similarly shaped movement and thereby move the annealing material step by step through the furnace.

Bei einzelnen dieser Vorrichtungen führt nur ein Teil der Herdbalken eine rechteckige Bewegung aus, durch welche das z. B. aus Feinblech bestehende Glühgut während der schrittweisen Förderung durch den Ofen auf die restlichen festen Herdbalken abgelegt wird, hier kurze Zeit ruht, um dann durch die vorgenannten beweglichen Herdteile weiterbefördert zu werden.In some of these devices only a part of the hearth beam leads a rectangular movement through which the z. B. made of sheet metal existing annealing material during the step-by-step conveyance through the oven onto the remaining solid hearth beams is stored, rests here for a short time, to then move through the aforementioned Stove parts to be conveyed on.

Bei anderen bekannten Vorrichtungen machen sämtliche Herdbalken eine rechteckige Bewegung in der Weise, daß ein Teil der das Glühgut tragenden Balken nach vorwärts läuft, während die restlichen leer laufenden Balken in einer tieferen- Lage gleichzeitig rückwärts bewegt werden. Bei der Verwendung derartiger Vorrichtungen erzielt man keinen ununterbrochenen. Durchgang des Glühgutes durch den Ofen, vielmehr wind die Förderbewegung durch kurze Stillstände unterbrochen.In other known devices, all hearth beams make one rectangular movement in such a way that part of the beams carrying the material to be annealed runs forward, while the remaining empty bars in a lower Position can be moved backwards at the same time. When using such devices one does not achieve an uninterrupted one. Passage of the annealing material through the furnace, rather wind the conveying movement is interrupted by brief stoppages.

Abgesehen von diesem Nachteil ist beiden vorgenannten Vorrichtungen mit einem verhältnismäßig hohen Kraftbedarf und dem dadurch bedingten starken Verschleiß der beweglichen Teile zu rechnen. Hierdurch sowie durch die vor jeder Vorwärtsbewegung in senkrechter Richtung und im gegenläufigen Sinne erfolgende Hub- bzw. Senkbewegung der unbelasteten bzw. belasteten Balkengruppen können bei empfindlichem Glühgut, z. B. bei Feinblechen, leicht mechanische Beschädigungen der Oberfläche auftreten, welche einen hohen- Prozentsatz an GlühgutausschuB im Gefolge haben.Apart from this disadvantage, both of the aforementioned devices with a relatively high power requirement and the resulting heavy wear of moving parts to be expected. As a result, as well as before each forward movement Lifting or lowering movement taking place in the vertical direction and in the opposite direction of the unloaded or loaded bar groups can be used for sensitive annealing material, z. B. with thin sheet, easy mechanical damage to the surface occurs, which result in a high percentage of incandescent material rejects.

Gemäß der Erfindung wird durch einen Teil der Herdbalken eine rechteckige, elliptische oder kreisförmige Bewegung ausgeführt, während die restlichen Balken lediglich vorwärts oder rückwärts bewegt werden. Man erreicht hierbei einen fast ununterbrochenen Durchgang des Glühgutes durch den Ofen, kann jedoch mit einem geringeren Kraftaufwand und weniger Verschleiß der beweglichen Teile rechnen als bei einer der vorgenannten bekannten Bauarten. Weiter wird, da nur die eine rechteckige Bewegung ausführenden Balken eine Hubbewegung machen, die Oberfläche von empfindlichem Glühgut naturgemäß mehr geschont als bei den bekannten, bereits erwähnten Vorrichtungen.According to the invention, a rectangular, elliptical or circular motion performed while the remaining beams can only be moved forward or backward. You almost reach you here uninterrupted passage of the annealing material through the furnace, but can be with a lower Expect effort and less wear and tear on the moving parts than with one of the aforementioned known types. Next, there will only be a rectangular movement executing bars make a lifting movement, the surface of sensitive annealing material naturally more spared than with the known, already mentioned devices.

B.Fig. I is a cross-section and Fig. 2 is a longitudinal section Example of a device according to the invention. The conveyance of the to be treated., z. B.

aus Feinblech bestehenden Gutes 15 erfolgt in der Weise, daß die beweglichen Herdteile io mittels der Hebelhubrollen i i und der Fahrbahn 12 eine rechteckige oder mittels eines anderen bekannten Antriebes eine elliptische, kreisförmige oder ähnlich geformte Bewegung ausführen und hierdurch in Verbindung mit den auf der Fahrbahn 13 lediglich vorwärts oder rückwärts laufenden Balken 1q. das Glühgut schrittweise durch .den Ofen befördern. Das Glühgut wird also durch die Hubbewegung der Herdteile io von den Herdteilen 14 abgehoben, durch die Vorwärtsbewegung ein Stück.in der Ofenrichtung bewegt, durch die Abwärtsbewegung wieder auf die Herdteile 14 gelegt, worauf die beweglichen Teile io in ihre Ausgangsstellung zurückkehren, während das Glühgut gleichzeitig durch die Herdteile 14 um ein weiteres Stück in der Ofenrichtung fortbewegt wird. Dieser Vorgang wiederholt sich stets von. neuem.made of sheet metal good 15 takes place in such a way that the movable Hearth parts io by means of the lever lift rollers i i and the track 12 a rectangular or by means of another known drive an elliptical, circular or perform similarly shaped movement and thereby in connection with the on the Lane 13 only forward or backward running bar 1q. the annealing material step by step through the oven. The annealing material is thus caused by the lifting movement of the hearth parts io lifted from the hearth parts 14, a piece in the forward movement Moved oven direction, placed back on the oven parts 14 by the downward movement, whereupon the moving parts return to their original position, while the Annealing material at the same time through the hearth parts 14 by a further piece in the furnace direction is moved. This process is always repeated from. new.
