Guide device for a strip rolling installation

Abstract

The invention relates to a guide device in an installation for deforming a material ( 1 ), including adjustable, extending parallel to each other, edge guides ( 3 a, 3 b ) arranged and positionable on both longitudinal sides ( 2 a, 2 b ) of the material ( 1 ), wherein the edge guides ( 3 a, 3 b ) are subjected to pressure applied by respective positioning devices ( 4 ), characterized in that the at least one positioning device ( 4 ) includes at least two pressure-applying devices ( 4 a, 4 b ) switchable seriesly one after another.

1 .

 characterized in that   the at least one positioning device ( 4 ) includes at least two pressure-applying devices ( 4   a ,  4   b ) switchable seriesly one after another.   
     
     
         2 . A guide device according to  claim 1 ,
 characterized in that   the pressure-applying devices ( 4   a ,  4   b ) include two, switchable seriesly one after another, piston-cylinder units.   
     
     
         3 . A guide device according to  claim 2 ,
 characterized in that   the two, switchable seriesly one after another, piston-cylinder units consist of comparatively large and comparatively small piston-cylinder units   
     
     
         4 . A guide device according to  claim 3 ,
 characterized in that   the comparatively small cylinder is mounted on a piston rod of the comparatively large cylinder, preferably, is integrated therein.   
     
     
         5 . A guide device according to  claim 1 ,
 characterized in that   connection of the pressure-applying devices ( 4   a ,  4   b ) is effected mechanically, preferably by at least one rack-pinion arrangement.   
     
     
         6 . A guide device according to  claim 1 ,
 characterized in that   a first pressure-applying device ( 4   a ) is secured in a desired location, and the pressure application to the material ( 1 ) is carried out exclusively by a second pressure-applying device ( 4   b ).   
     
     
         7 . A guide device according to  claim 1 ,
 characterized in that   at least one pressure-applying device ( 4   a ,  4   b ) having two, switchable seriesly one after another, piston-cylinder units is connected only with one of edge guides ( 3   a ,  3   b ).   
     
     
         8 . A guide device according to  claim 1 ,
 characterized in that   the edge guides ( 3   a ,  3   b ) are adjusted independently from each other.   
     
     
         9 . A guide device according to one of the foregoing  claim 1 ,
 characterized in that   regulating and/or controlling units are connected with at least one positioning device ( 4 ).   
     
     
         10 . A guide device according to  claim 9 ,
 characterized in that   the pressure-applying devices ( 4   a ,  4   b ) are controlled or regulated independently from each other.   
     
     
         11 . A guide device according to one of the foregoing  claim 1 ,
 characterized in that   at least one guide rail ( 15 ) contributes to the adjustment of the edge guides ( 3   a ,  3   b ) transverse to the material ( 1 ).   
     
     
         12 . A guide device according to one of the foregoing  claim 1 ,
 characterized in that   it is a component of a metal rolling mill, preferably, of a strip rolling mill.   
     
     
         13 . A guide device according to  claim 12 ,
 characterized in that   it is arranged at the outlet side of at least one rolling mill stand of a finishing rolling mill train.   
     
     
         14 . A guide device according to  claim 12 ,
 characterized in that   it is arranged at the inlet side of at least one rolling mill stand of the finishing rolling mill train.
