Definitions

  • This invention relates to a rolling mill of the type comprising a first set of vertical rolls, a set of horizontal rolls and a second set of vertical rolls, the sets of rolls being disposed very close together.
  • a mill of that type is described and illustrated in British Patent Specification No.1390537 and will be referred to hereinafter as a "triplet mill".
  • a triplet mill comprises a housing structure defining a chamber, a pair of horizontal rolls and two pairs of vertical rolls contained within the chamber with one pair of vertical rolls disposed on one side of the pair of horizontal rolls and the other-pair of vertical rolls disposed on the opposite side of the pair of horizontal rolls and in the direction parallel to the direction of movement of material through the mill, the bearing chock assembly of each pair of vertical rolls abuts against the housing structure on one side and against the bearing chocks of the horizontal rolls on the other side.
  • each roll is rotatably mounted in a pair of bearing chocks and the bearing chocks of the horizontal rolls abut against the bearing chocks of the vertical rolls.
  • each roll is mounted in a pair of bearing chocks and the bearing chocks of each vertical roll of each pair of vertical rolls are arranged in a cassette having a pair of opposed side plates constituting part of the bearing chock assembly. It is the side plates which abut against the housing structure and the bearing chocks of the horizontal rolls.
  • the construction according to this invention enables roll changing to be carried out with relative ease.
  • a triplet mill comprises a housing structure 1 containing a pair of horizontal rolls and two pairs of vertical rolls.
  • the horizontal rolls are driven by a motor 3 through a pinion box 5 and a pair of drive spindles 6.
  • Each pair of vertical rolls are driven from their lower end by means of a drive motor 7, a drive shaft 9 and a pinion box 10.
  • the vertical rolls may be driven from their upper end.
  • the structure 1 defines a chamber 11 in which the rolls are located.
  • Each of the horizontal rolls 13 is provided with bearing chocks 15 at its roll neck and each of the vertical rolls 17, 19 is provided with bearing chocks 21 at its roll neck.
  • the bearing chocks constitute a bearing chock assembly for the rolls.
  • the bearing chocks 21 abut against the housing structure on one side and against the bearing chocks 15on the other.
  • the rolls of each pair of vertical rolls are movable horizontally towards and away from each other to vary the gap between them, and the horizontal rolls can be raised or lowered to adjust the gap between them. Wear plates provided on the bearing chocks permit the relative movement between the chocks to readily take place.
  • the housing structure defines an opening 25 through which the roll assemblies are displaced for roll changing purposes.
  • the roll changing process is as follows:-
  • the trolley supported on the guides 29 is displaced by one step along the guides, thus enabling worn rolls to be positioned on the trolley and replacement rolls to be displaced from the trolley into the mill.
  • each pair of vertical tolls and their bearing chocks are located within a cassette which forms part of the bearing chock assembly for the pair of rolls.
  • the vertical rolls 19 are supported in bearing chocks 21 and the rolls are positioned between a pair of parallel plates 30 joined together by straps 31 to form a cassette.
  • the bearing chocks 21 rest on the plates 30.
  • the bearing chocks and the cassette constitute a bearing chock assembly for the two vertical rolls 19.
  • the rolls 17 are supported in bearing chocks 21 and the rolls are positioned in a cassette formed by parallel plates 30 joined together by straps 31.
  • the bearing chocks and the cassette constitute a bearing chock assembly for the two vertical rolls 17.
  • the bearing chock assembly of each pair of vertical rolls abuts against the housing on one side and against the bearing.chocks of the horizontal rolls on the other side.
  • An opening 32 in each of the parallel plates 30 enables the workpiece to be passed between the rolls.
