Definitions

  • the invention relates to a rolling mill associated Bridleech with several adjustable below and above the tape arranged rollers, by means of a drive from a home position to the tape and from the tape back in the starting position are movable.
  • Bridle units guide and straighten the belt and maintain its tension by arranged above the tape run adjustable rollers by means of Drive from the initial position on the belt surface in a working position be lowered.
  • the alternately bent band leaves in the working position the Bridleech at the nip of the associated rolling mill nearest Roller at the level of the pass line of the roll stand.
  • Bridle units of this type are known, for example, from JP-A-52 052852, JP-A-51 No. 109,264 and US Pat. No. 2,768,542. It is further known from US Pat. the one closest to the roll gap of the roll stand both from above as can be made from below to the band.
  • an additional color roll must be used between the Bridleech and the associated rolling mill.
  • the additional color roll and the mechanical equipment required for its operation extend the distance between the nip of the roll stand and the unwinding of the band. With the larger distance between nip and However, uncoiling are procedural disadvantages, in particular larger dimension lengths connected.
  • the invention is therefore an object of the invention to provide a Bridleech, the a coloring of the tape without lengthening the distance between the nip and uncoiling allows.
  • the solution to this problem is based on the idea that the nip of the mill stand decouple the next roll so that the roll can be used as a bridle roll or color roll is usable.
  • the object is a Bridleech of the type mentioned solved by the roller closest to the roll gap of the roll stand by means of an additional drive from a starting position below the tape run or from a starting position above the tape to the tape movable is, wherein the scope of the role when using the Bridletician to Colorize the tape the tape up or down from the horizontal Throughline deflects and an inlet angle above or below the Pass line forms.
  • the roll gap close roll either as Bridie or Colorrolle to be able to use, increases the distance between the nip and unraveling even if an additional coloring of the Bandes is required.
  • roller closest to the roll gap of the roll in any Intermediate positions between the starting positions above and below the tape run is movable, can be different entry angle to Set the pass line when coloring the ribbon. Also allowed this feature an improved adaptation of the bridle unit to different bands Thickness in both Bridle and Colorize modes. process engineering reasonable entry angles are between +/- 14 ° the pass line.
  • a position sensor is provided which detects the position of the roller.
  • the additional drive for the roll gap close roll is in an appropriate embodiment the invention as both sides acted upon, fluid-operated, in particular designed hydraulic cylinder.
  • the additional drive for the roll gap close roll is in an appropriate embodiment the invention as both sides acted upon, fluid-operated, in particular designed hydraulic cylinder.
  • the Bridle unit according to the invention is for all rolling mills for rolling of non-ferrous metals or steels in which a Bridle unit with several roles is required and at the same time the requirement of one of the Pass line deviating inlet angle of the strip in the roll stand is.
  • the rolling stands not as a one-way but as Reversiergerüste executed, it is preferable to arrange the Bridle unit according to the invention on both sides.
  • FIG. 1 shows a rolling stand 1 which is partially shown Bridle unit 2, whose arranged above the tape rollers 3 from the in The starting position shown in Figure 1 movable in a working position are in which the rollers 3 rest on the belt 4 (see Figures 2b, 3b and 4b.
  • rollers 3 Two other roles. 5 fixedly arranged in bearing blocks 6, the roller shells 7 are up to the in Figure 1 shown pass line 8 of the belt 4 not shown extend.
  • a roller 11 of the rolling stand 1 closest to the roll gap 9 of the roll stand 1 2 is vertical to the pass line 8 from the starting position shown in Figure 1 12 below the tape in a starting position shown in Figure 3a 13 above the tape and each position between the Starting positions 12 and 13 movable.
  • the starting position 12 of the roller gap near roller 11 corresponds to the position the fixed below the tape running rollers 5, while the starting position 13 of the roll gap near roll 11 of the starting position of above the tape running arranged adjustable rollers 3 corresponds (see FIG 3a).
  • FIGS. 2 a, 3 a and 4 a show the threading of the band for the respective one Operating mode and Figures 2b, 3b and 4b show the operating mode itself:
  • the bridle unit If the bridle unit is to be operated in the bridle mode according to FIG. 2b, it remains the roll gap near roller 11 in its initial position 12 at the level of fixed Rollers 5.
  • the arranged on a support frame 14 rollers 3 moves a hydraulic cylinder 15 from the home position 16 in the direction of Top of the band 4, so that the band 4 by the rollers 3, 5, 11 alternately bent and the roll gap near roll 11 at the level of the pass line. 8 leaves.
  • rollers 3 and the roller gap near roller 11 each brought to their original position 13, 16 and the tape is placed on the two fixed rollers 5. Subsequently, the Rolls 3 according to Figure 3b on the top of the belt 4 to produce lowered a bending change.
  • the roller role acting as Colorrolle 11 is opposite the rollers 3 lowered a little further to one of the pass line 8 different inlet angle of the belt in the nip 9 set.
  • rollers 3 To color the underside of the band 4, the rollers 3 are in their starting position 16 and the roll gap near roll 11 in its starting position 12th brought and the tape on the two fixed rollers 5 and the roll gap near Roll 11 launched. Subsequently, the rollers 3 according to Figure 4b lowered to the top of the belt 4 to produce a reciprocal bend.
  • the roller roll 11, which acts as a roller for rolls, is opposite to the roller roll 11 which acts as a roller fixed rollers 5 slightly raised to one different from the pass line 8 Adjustment angle of the belt in the nip 9 set.
  • a hydraulic cylinder 18 adjustable To the inlet angle, for example, to different tape thicknesses, tape speeds or to be able to adjust strip materials steplessly is the roll gap near roll 11 in any intermediate positions between the starting positions 12 and 13 by means of a hydraulic cylinder 18 adjustable.
  • the Piston rod 19 of the hydraulic cylinder 18 engages a in a vertical guide 21 slidably guided support frame 22 at.
  • the right angle formed Shoring 22 allows an arrangement of the hydraulic cylinder 18 directly arranged next to the hydraulic cylinder 15 for the above the tape run, adjustable rollers 3 of the Bridle unit 2.
  • the spatially close arrangement the hydraulic cylinder 15, 18 in conjunction with the angled Shoring 22 allows a smaller distance to the rolling mill 1, as a straight version of the shoring in straight extension of the piston rod 19 of the hydraulic cylinder 18th
  • the embodiments illustrate that in the direction of the pass line 8 in the axial distance with the other roles matching roll gap near Roll 11 arranged by the decoupling of the rest below the tape run Rolls 5 the dual function of the invention without disadvantages for complies with the rolling process, in particular because the Bauicarde the Bridleritt unchanged is. An extension of the distance between the nip 9 and the Coiling is therefore not associated with the Bridleiser invention.
