Definitions

  • the present invention relates to improvements in diagonal rolling mills, and here particularly to mills of the type using two rolls for piercing solid billets by the Mannesmann process of making seamless tubing.
  • Diagonal and piercing rolling mills of the type referred to above usually employ rolls which have their axes arranged in a horizontal plane.
  • the solid billet to be rolled is supported in that the pass is closed from below by means of a straight edge, which is disposed between the rolls.
  • the pass may additionally be closed from above by means of another straight edge.
  • Some mills are provided with driven guide disks in lieu of the straight edges. These disks are more expensive but wear better and need less frequent replacement than straight edges.
  • the guide disk system is to be equipped with a simple drive and is to be constructed for easy adjustment of the disposition of these disks on the rolling pass.
  • the rolling mill to be improved has a rolling stand with a pair of rolls whose axes are inclined to the rolling axis and to each other. Also, there is a pair of driven guide disks which are staggeredly arranged in the plane transverse to the direction and axis of rolling.
  • the rolls one above the other on the mill floor, and the guide disks are provided with vertical shafts; there being apertures in the roll housing through which the guide disks engage the billet in the pass, from opposite sides. Additionally, it is suggested to support the guide disks on the housing, but laterally offset to the pass, to permit retraction of the disks from the pass, in opposite directions.
  • the guide disks are journalled in journal blocks on the housing; these blocks can be displaced transverse to the rolling axis and parallel (or colinear) to each other, but in such a manner that the dispositions are restorable.
  • the arrangement for journalling and supporting the guide disks must remain independent from settling example, by means of eccentrically mounted bushings.
  • the guide disks can be removed from their disposition on the pass through lateral displacement from the lateral access opening in the stand. There is no other equipment in the way which could impede that displacement.
  • the disks are driven either by motors disposed outside of the stand or via linkage and spindles.
  • the drive mechanism for the disks may be disposed laterally, outside and below the pass and is, thus, protected against contamination.
  • the drives for the disks impart a particular rotational speed upon the disks.
  • the value of the peripheral speed is about ten to twentyfold the speed of the rolled and pierced billet and as passing through the stand.
  • the motors needed here were quite large and powerful. Actually, they could not even be mounted on the rolling stand.
  • FIG. 1 is a vertical cross section through a mill stand of a skew rolling mill, improved in accordance with the preferred embodiment of the invention.
  • FIG. 2 is a horizontal cross section of the stand shown in FIG. I, the section plane taken in the level of the guide disks.
  • FIG. 1 shows a roll housing I for a diagonal rolling mill with cover 2 and two rolls 3 and 4 which are arranged in the housing one above each other.
  • the rolls are oblique to the normal of the plane of the drawing in FIG. 1 (see FIG. 2 as to roll 4).
  • the rolls have journals 41 and 42 respectively, indicated in phantom lines in FIG. 1 in such a manner so as to denote the orientation of the relative skew angles of the rolls to which they pertain.
  • Reference numerals 5 and 6 refer to construction for synchronously adjusting the position of the rolls by operation of adjusting drives 7 and 8.
  • the rolling stand has upright disposition on foundation and mill floor 9.
  • the rolls 3 and 4 revolve in similar directions and work on a pipe 10 pierced by a mandrel 11.
  • a pair of guide disks l2 and 13 engage the pipe 10 from opposite sides in a horizontal plane of the pass and between the rolls 3 and 4.
  • the disks l2 and 13 have groove contour on their periphery and preventing the billet from assuming oval cross section. It can readily be seen from FIG. 1 that rolls and disks are staggeredly or alternatingly arranged around the axis of rolling.
  • Disks 12 and 13 are respectively driven by motors 16 and 17, whose output shafts are geared to the disks by the gears 18 and 19, respectively.
  • the disks 12 and 13 are placed on spindles and locked thereto by threaded fasteners 34 and 35.
  • the spindles or axles for the disks carry gears which mesh with gears on the drive shafts of motors 16 and 17.
  • the spindles for the disks are respectively journalled on pivot arms 20 and 21 for pivoting into and out of lateral access openings and 15 in the housing 1. Upon pivoting the arms, the disk spindles are moved into and out of gear.
  • FIG. 2 Particulars of the arms and 21 can be derived from FIG. 2. Pivots are established by eccentric bushings 24 and 25, on but outside of housing 1. Arrow 26 denotes the direction of rolling, of the rolling axis and of pipe advance. Disks 12 and 13 are, therefor, mounted for pivoting on vertical axes, transverse to the direction 26, but the bushings permit adjustment of the arms in direction 26 of rolling, so that the disks can be properly positioned along the pass.
  • pivot arms 20 and 21 are held in position by means of brackets or clamps 26 and 27 with cylinders 28, 29, but threaded adjusting spindles 30 and 31 permit accurate positioning of the pivot arms so as to determine the disposition of the portions of disks 12 and 13 as projecting into the rolling pass.
  • disks 12 and 13 For replacing worn disks 12 and '13, cylinders 28 and 29 are retracted and clamps or brackets 26, 27 pivot so as to release the arms 20, 21. Now arms 20 and 21 can be pivoted for retracting disks 12 and 13 from the access openings 15 and 16 in housing 1. After releasing fasteners 34, 35, disks l2 and 13 are slipped off their respective spindles in up direction. Please note that motors and gears are disposed below the disks so that no impediment prevents easy replacement of the disks. Newly placed disks 12 and 13 may be adjusted as to height on the pass by means of washers such as 36 and 37. Particularly, the disks l2 and 13 should have their (horizontal) center planes traverse the center line between the rolls in the pass.
  • a diagonal rolling mill having a stand on a mill floor and a pair of rolls in a housing, the rolls being inclined to the axis of rolling in the pass as well as to each other, the improvement comprising:
  • the rolls of the pair arranged one above the other relative to the mill floor, the roll housing having lateral access openings for access to the pass from opposite sides;
  • the arms extending alongside the housing and respectively pivoted with one of their ends on the housing, on the outside thereof, and to one side of the respective opening along the pass, the means for locking being operative at the other free ends of the arms and to the other side of the respective opening along the pass, the disks being journalled on the arms, between the free ends and the pivoted ends, to reach through the openings, upon unlocking the other ends of the arms the arms can be pivoted away from the rolling axis.
