Definitions

  • the invention relates to a method and a device for deflecting and reorienting the running direction of strips, in particular thin hot strip, the strip being deflectable by any angle via at least one deflecting roller, by means of roller banks arranged on the circumference of the deflecting roller, each of which has several Include single roles.
  • a belt deflection device for deflecting metal strips in which a rotatable drum is aligned with its axis inclined to the running direction of the incoming strip and takes up the strip along a helical path that rises at an angle of inclination with respect to the circumferential arc along a loop.
  • a plurality of guide pieces are arranged on the drum jacket next to one another in the circumferential direction and displaceably in the axial direction of the drum, so that the belt is deflected at the desired angle in accordance with the pitch angle and the looping curve (DE 2540 714 A1).
  • the individual rollers are mounted in roller strips and releasably fastened parallel and offset to one another on the surface of the deflecting cylinder, forming a helical deflecting surface.
  • the invention is based on the object of specifying a method according to which plastic and elastic deformations, which occur in particular when deflecting and redirecting thin strips, are prevented.
  • a device suitable for performing this method is to be created.
  • the invention is based here on the idea that the first roll of the second roll bank, viewed in the direction of the belt travel, is arranged in the region of the belt that lies between the first and second roll of the first roll bank.
  • the invention also relates to a device which is particularly suitable for carrying out the claimed method and which has at least two roller banks, each with at least two rollers.
  • Figure 1 as a detail of a pulley with incoming and outgoing tape.
  • FIG. 2 seen the deflection roller according to FIG. 1 from an end face
  • FIG. 3 shows, as a detail of the deflection roller according to FIG. 2, a roller bench in a top view
  • FIG. 4 shows the deflection roller according to FIG. 1 in a perspective view with an additional arrangement of a control roller stand
  • FIG. 6 shows a development showing two successive roller banks of the deflection roller according to FIG. 2;
  • Fig. 7 is an illustration as in Fig. 6 but with wider roles.
  • a strip 1 is fed to the deflection roller 2 when it is deflected by 90 ° at an angle of 45 ° to the longitudinal axis 3 and is likewise removed again at 45 °.
  • the belt 1 wraps around the deflection roller 2 over half the circumference.
  • the rollers 4, arranged in banks 5, are distributed over the area of the deflection roller 2 which is wrapped by the belt 1.
  • roller banks 5 which are arranged at a uniform angle and spaced over half the circumference of the deflection roller 2.
  • the individual rollers 4 are aligned on a roller bench 5 at 45 °.
  • the belt 1 is supported by six rollers 4 (R1 to R6). These six rollers 4 (R1 to R6) have the same diameter 6 and the same width 7.
  • the distance 8 from the center width of the first roll R1 and the center width of the sixth roll R6 corresponds to the width 9 of the belt.
  • the right and left edge of the belt 1 thus lies on the central axis 10 of the rollers R1 and R6 and is supported.
  • a control roller stand 11 is additionally arranged, which leads to the establishment of a constant tension on the belt 1.
  • the support of the edge of the band 1 can be seen by the roller 4, which is only covered by the band 1 on one half.
  • Fig. 5 shows the tape 1 as it is evenly supported by the individual rollers 4 of the roller banks 5.
  • FIG. 6 A processing with two roller banks 5 of the deflection according to FIG. 2 is shown in FIG. 6.
  • the contact with the rollers 4 of the roller bank 5 from the first roller bank 5 to the next roller bank 5 is offset by the width of a roller 4.
  • rollers with slightly changed diameters also results in a staggered contact between the belt and rollers.
  • the measures described avoid the imprints and flatness errors which occur in the known devices, in particular in the case of thin hot strip.
