  Vorrichtlmg zum Anpressen der unteren Arbeitswalze von Walzgerüsten an ihre Stützwalze 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 



   Es ist üblich, die Walzgerüste mit einer Walzenausbauvorrichtung zu versehen. Diese besteht beispielsweise aus hydraulisch betriebenen Hubzylindern 14,15, 16 (der vierte Zylinder ist in der Zeichnung nicht sichtbar), auf deren Kolben 17, 18, 19 Laufschienen 20,21 abgestützt sind. Auf diesen ruhen am Einbaustück 22 der unteren Stützwalze 5 vorgesehene Laufräder 23,24, die zum Ausfahren des Einbaustückes beim Walzenwechsel dienen. 



   Erfindungsgemäss wird die vorstehend beschriebene Einrichtung, deren Kolben sich beim Walzenwechsel aufwärts bewegen, gleichzeitig zum Anheben des Gewichtes 6 und damit zur Freigabe des Einbaustückes 13 der unteren Arbeitswalze 4 benutzt. Um dies zu erreichen, sind mit den Laufschienen 20,21 Querträger 25,26 und mit diesen nach unten ragende Zugstangen 27,28, 29 verbunden, die mit auf ihre unteren Enden aufgeschraubten Muttern 30,31, 32 unter Zwischenschaltung von Pufferfedern 33, 34, 35 unter Ansätze 36, 37 des Gewichtes 6 greifen.

  Device for pressing the lower work roll of rolling stands against their support roll
 EMI1.1
 

 <Desc / Clms Page number 2>

 



   It is customary to provide the roll stands with a roll removal device. This consists for example of hydraulically operated lifting cylinders 14, 15, 16 (the fourth cylinder is not visible in the drawing), on whose pistons 17, 18, 19 running rails 20, 21 are supported. On these rest on the chock 22 of the lower support roll 5 provided running wheels 23, 24, which serve to extend the chock when the roll is changed.



   According to the invention, the device described above, the pistons of which move upwards when the roll is changed, is used at the same time to lift the weight 6 and thus to release the chock 13 of the lower work roll 4. In order to achieve this, cross members 25, 26 and downwardly projecting tie rods 27, 28, 29 are connected to the running rails 20, 21, which are connected to nuts 30, 31, 32 with the interposition of buffer springs 33, 34 , 35 under approaches 36, 37 of the weight 6 grab.
