Definitions

  • the invention relates to a pair of upsetting rollers for upsetting the flange edges of symmetrical profile steels, in particular double-T beams, each upsetting roller having a bale which engages in the inner contour of the profile and which guides the profile and two conical outwardly extending upsetting paths for the bale which adjoins the bale on both sides Has flange edges of the profile.
  • rolling mills are particularly suitable, which are composed of universal rolling stands and interacting upsetting stands.
  • the pre-profile in the universal stands is reduced in several successive reversing stitches, while the free-extending flanges are formed by upsetting their flange edges in upsetting stands.
  • upsetting rollers that have a bale that guides the profile, in addition to which upsetting tracks are provided on both sides for the flange edges.
  • These upsetting tracks are formed by tapered sections of the roller, the cone running outwards, ie the upsetting tracks increase their diameter from the bale to the outside.
  • the bale of the upsetting roller engages in the inner contour of the profile and guides it through the contact of the bale flanks on the inner flanks of the flanges of the profile.
  • a gap should remain between the outer diameter of the bale and the web of the profile to be rolled, so that the different peripheral speeds of the outer diameter of the bale and the dipping paths do not have a negative effect.
  • it must be ensured that the play between the outer diameter of the bale and the web of the profile does not become too large, because otherwise exact centering of the profile is no longer possible.
  • the profile floats in the roll gap and the flanges and the web are bent, which cannot be tolerated.
  • bale of the upsetting roller is designed there from two eccentrically mounted rings that slide freely on an adjustable bearing body. By adjusting eccentric intermediate rings, the position of the outer ring with respect to the center of the web of the profile can be changed and thus the gap of the outer diameter of the roll barrel can be changed.
  • the disadvantage of the known solution is that the upsetting roller, due to the eccentric bearing against each other, has a very high manufacturing cost and at the same time a large expected wear. With the eccentric adjustment of the bale composed of two disks, the chamber dimension of the roller also changes, which is also disadvantageous .
  • the previously known solution cannot be retrofitted to existing roll stands because extensive renovation work would be necessary.
  • JP-A-4-172 106 discloses a pair of upsetting rolls for upsetting the flange edges of symmetrical section steels, in which sleeves or roll rings form a closed caliber. An adjustment of this in the axial direction changes the upsetting path and thus the flange width.
  • the present invention has for its object to form an upsetting roller for an upsetting roller pair for upsetting the flange edges of symmetrical section steels in such a way that with simple means, which can also be used retrospectively with existing roll stands, an exact with widened flanges Center position adjustment of the profiles is possible with optimal guidance.
  • the upsetting paths are formed by the conical outer circumference of the bushings guided coaxially displaceably on both sides of the bale on the roller body, the mutually facing end faces of the bushings in annular recesses of the bale intervention.
  • the bushings can be moved hydraulically, and of course a mechanical shift is also conceivable.
  • the axial depth of the annular recesses of the bale is greater than the section of the respective bushing that can be moved into the recesses and corresponds at least to the displacement path of the respective bushing.
  • An upsetting roller pair of the invention consists of the upper upsetting roller 1 and the lower upsetting roller 2, by means of which a double-T profile 3 is compressed in several passes between the respective previous universal passes.
  • the upsetting rollers 1 and 2 consist of the bale 4 and the upsetting tracks 5, which extend on both sides of the bale 4 and run conically outwards.
  • the bale 4 is part of the roller body 6, while the upsetting tracks 5 are provided on the outer surface of conical bushings 7, which are axially displaceable on cylindrical sliding sections 8 of the rolling body 6.
  • the end faces 9 of the bushings 7 protrude into annular recesses 10 of the roller body 6 in the region of the bales 4, together with sections 11 of the conical bushings 7, the length of which corresponds approximately to the displacement path of the conical bushings 7.
  • the annular pistons 12 are provided, the piston chambers 13 of which can be acted upon by hydraulic fluid.
  • the bushing 7 moves into the end position shown in the drawing, in which the section 11 of the bushings 7 plunge deeply into recesses 10 of the roller body 6.
  • the bushings 7 By acting on the piston surfaces 18 with pressure oil via the lines 15 with the corresponding activation of the lines 14, the bushings 7 can be displaced outwards, the sections 11 being partially led out of the annular recesses 10.
  • the bushings 7 slide on the sliding surfaces 8 and the sections 11 in the recesses 10 at 16, so that the bushing 7 is always supported with respect to the roller body 6.
  • the bushings 7 With the movement of the bushings 7 to the outside, the diameter of the compression paths acting on the flange edges is reduced, so that a larger flange width can be machined without the immersion depth of the bales 4 being changed in the regions of the web 17 of the double-T profile 3 .
  • the adjustment of the bushings 7 can be easily carried out between two upsetting stitches during the rolling operation, so that an adaptation of the upsetting roller 1, 2 to the required upsetting process is easy and reliable with simple means.
  • a particular advantage of the invention is that the device according to the invention can also be retrofitted to conventional upsetting rollers without the stability of the roller being weakened in a questionable manner.
