Description
Die bekannten Siederohrdichtmaschinen haben im allgemeinen drei bis fünf Walzrollen, welche aus Schlitzen mit gleichem Abstand voneinander aus dem Umfang des 5 oberen Gehäuseteils durch den Dorn herausgedrückt werden.The known boiler pipe sealing machines generally have three to five rolling rollers, which are pushed out of slots at the same distance from each other from the circumference of the 5 upper housing part through the mandrel will.
Da in dem Umfang des Loches einer Kesselrohrwand infolge der benachbarten Anordnung weiterer Löcher der den WalzrohrenBecause in the circumference of the hole of a boiler tube wall due to the adjacent arrangement further holes of the rolled tubes
to entgegentretende Druckwiderstand verschieden ist, kommt es beim Einwalzen der Rohre leicht vor, daß sich Unrundungen im Lochumfang bilden.to the opposing pressure resistance is different, it occurs when the pipes are rolled in It is easy for out-of-roundings to form in the circumference of the hole.
Nachteil der Anordnung der Walzrollen in gleichem Abstand voneinander ist, daß sich diese unrunden Stellen entsprechend der Anzahl der Walzrollen auf entsprechend viele Stellen des Lochumfanges übertragen, da.beim Drehen des Domes der Dichtmaschine die Walzrollen jedesmal in dieselben unrunden Stellen gelangen, so daß in dieser Stellung des Domes der Druck von den Walzrollen nachläßt und das Nachstellen des Vorschubes erfolgt. Hierdurch werden die Ausbeulungen in der Lochrundung nicht nur dauernd verstärkt, sondern auch auf die jeweiligen Stellen der übrigen Walzrollen im Loch übertragen. Disadvantage of the arrangement of the rolling rollers at the same distance from each other is that these out-of-round places according to the number of rollers to a corresponding number Transfer the positions of the hole circumference, because when turning the dome of the sealing machine the Rolling rollers get into the same out-of-round places each time, so that in this position of the dome, the pressure from the rollers decreases and the readjustment of the feed he follows. This not only permanently reinforces the bulges in the rounding of the holes, but also transferred to the respective locations of the remaining rollers in the hole.
Diese Nachteile der bisher bekannten Siederohrdichtmaschine werden dadurch vermieden, daß der Abstand der Walzrollenschlitze in dem Umfang des Gehäuses untereinander verschieden groß ausgeführt wird, so daß jedesmal, wenn eine der vorhandenen Walzrollen an einer bestimmten Stelle des Lochumfanges ist, die anderen Walzrollen an stets verschiedenen Stellen des Lochumfanges sich befinden.These disadvantages of the previously known boiler pipe sealing machine are avoided in that the distance between the rolling roller slots in the circumference of the housing is made of different sizes, so that every time one of the existing rolling rollers is at a certain point on the circumference of the hole, the other rollers always different points of the hole circumference are.
Beiliegende Zeichnung vergegenwärtigt eine beispielsweise Ausführungsform der neuen Siederohrdichtmaschine, und zwar stellen dar:The accompanying drawing shows an example embodiment of the new one Boiler pipe sealing machine, namely represent:
Fig. ι eine Ansicht der Siederohrdichtmaschine, Fig. Ι a view of the boiling pipe sealing machine,
Fig. 2 einen Querschnitt durch den Dom und die Walzrollen.2 shows a cross section through the dome and the rolling rollers.
Die Schlitze g, h und / für die Walzrollen c, d und e im Gehäuseteil/ der Rohrwalze a haben voneinander verschieden große Abstände, und zwar ist der Abstand zwischen den Schlitzen g" und h größer als der Abstand zwischen den Schlitzen h- und /, dagegen kleiner als der Abstand zwischen den Schlitzen / und g. The slots g, h and / for the rolling rollers c, d and e in the housing part / the tube roller a have different distances from one another, namely the distance between the slots g ″ and h is greater than the distance between the slots h and / , on the other hand smaller than the distance between the slots / and g.
Bei einer Siederohrdichtmaschine mit beispielsweise fünf Walzrollen wurden in entsprechender Weise die fünf Abstände zwischen den benachbarten Walzrollen verschieden groß sein.In the case of a boiler pipe sealing machine with, for example, five rollers, corresponding Way, the five distances between the adjacent rolling rollers may be of different sizes.
