Definitions

  • the invention relates to a device for lateral guidance of the flanges of steel profiles, in particular a profile support in a flange compression frame within a reversing tandem frame group consisting of a universal frame, compression frame and universal frame, each flange guide being constructed in several parts and the flange guide piece in the area of the roller chocks arranged in the frame window is arranged interchangeably and / or displaceably.
  • the known one-piece flange guides also have the disadvantage that when changing the roll, the upper roll and its chocks must be raised above the upper edge of the side guides in order to move the roll and chock out of the window of the roll stand to the operating side.
  • a fork-like support structure is attached to a movable transfer platform, which is pushed between the extended rollers when the roller is changed by means of the transfer platform.
  • the lower fork is supported on the lower chocks; the upper fork carries the upper roller together with its chocks.
  • the fork construction has to be designed to be particularly solid and torsionally rigid due to the heavy loads of the roller and chocks, which ultimately causes high material and manufacturing costs.
  • the object of the present invention is to improve the side flange guides in a flange compression stand of a profile line of the type mentioned at the outset, in particular to avoid the flanges of a profile carrier breaking out laterally in the region of the rollers and at the same time the two guides for the flanges To be designed so that the previously known complex supporting structures required for changing the roller can be omitted.
  • each flange guide piece is narrower than the width B of the scaffold window and can be locked with the upper and lower roller chocks to form an exchangeable roller set.
  • the height of the outer flange guide elements on the frame side is dimensioned according to the maximum flange width of a profile support program, a safe flange guide is also guaranteed both in the inlet and in the outlet area of the compression frame.
  • the displaceable arrangement of the flange guide piece ensures optimal alignment of this guide surface with the guide surfaces of the flange-side flange guide elements.
  • the flange guide piece is designed to be a spacer piece which can be displaced between the roll chocks, so that the guide pieces can also be used as spacer pieces in order to keep the rolls apart when changing the rolls.
  • These parts are extended with the roller set when changing the rollers.
  • the previously known complex lifting and supporting structures on the movable transfer platforms are no longer required, since the rollers are only slightly raised from one another.
  • the side flange guide no longer hinders the roll change, since the flange guide piece is narrower than the width of the scaffold window. It is advisable to adapt the flange guide piece as far as possible to the width of the scaffold window, so that on both sides of the cut-outs due to the roll diameter, sufficient supporting material remains on which the roll chocks can be supported.
  • the flange guide pieces are moved back as roller spacers from the guide surface formed with the flange guide elements into the stand area until they lock into place with the roller chocks.
  • the assembly thus produced consisting of a lower roller with chocks, an upper roller with Chocks and spacer-spaced flange guide pieces can be moved out of the compression frame as a unit, for example via wheel sets attached to the chocks of the lower roller.
  • Each flange guide piece is expediently provided with at least one adjustment pin which engages in an appropriately designed adjustment hole which is embedded in the roller chock.
  • the scaffold-side flange guide elements are guided through the scaffold window of the upsetting frame approximately transversely to the rolling line and are connected to a locking bar to form a U-shaped cutout, and that in this cutout the flange guide piece is displaceable and can be locked against a stop.
  • the locking bar on the drive side of the roll stand is firmly connected to the flange guide elements, while the locking bar on the operating side of the roll stand is releasably connected to the flange guide elements and at the same time an integral part of the flange guide piece is. Moving the set of rolls out of the roll stand towards the operating side is made considerably easier as a result.
  • the height of the flange-side flange guide elements and the connection height of the flange guide piece correspond to the full flange width of a steel profile to be guided in the roll stand, the height of the flange guide piece in the area of the rollers being approximately the respective flange width to be guided a steel profile is adapted.
  • the entire range of profiles of a rolling program - as far as the flange guidance of the individual prototype rods is concerned - can be covered perfectly with just a few graduated flange guide pieces. With three to four different flange guide pieces, it will be possible to properly guide more than a hundred different steel profiles in the compression frame.
  • FIG. 1 schematically shows a high-performance rolling mill for IPE and I-beams with a roughing stand 1, a downstream reversing tandem group, consisting of a universal stand 2, a flange upsetting stand 3 and a universal stand 4.
  • the reversing tandem group is a finishing group 5, Consisting of flange compression tower and universal tower.
  • the shape stitches and the upsetting stitches are indicated with arrows in the direction.
  • Fig. 2 shows the reverse tandem group in an enlarged view in order to make the arrangement of the flange side guides visible, for example for a profile beam, in the flange upsetting stand 3.
  • the previously known flange side guide is shown again enlarged in FIG. 3.
  • the flange side guide 6 has so far been made in one piece and has deep sectoral cutouts 7 in the area of the rollers, so that profile beams with a small flange width of approximately 100 mm can also be rolled.
  • the deep cutouts 7 clearly interrupt the flange guide in the area of the rollers, so that there is a risk of damage to the flanges of the profile carrier and the rollers in this area.
  • FIGS. 4 and 5 show the new development according to the invention, according to which each lateral flange guide 6 is designed in several parts - in the present case three parts - and with a central flange guide piece 8 and two lateral flange guide elements 9, 10.
  • a relatively wide flange 11 of a T-section support 12 is compressed by the horizontal rollers 13, 14.
  • 6 and 7 show the rolling of a very low profile T-beam 12 'with narrow flanges 11' between the rollers 13 'and 14'. 5 that the cutout 7 determined by the rollers 13, 14 in the flange guide piece 8 is shaped substantially differently than the cutout 7 'in the flange guide piece 8' according to FIG. 7.
  • the height H of the stand-side flange guide elements 9, 10 roughly corresponds to the full maximum flange width of the profile beam to be guided in the roll stand
  • the height h of the flange guide piece 8, 8 'in the region of the rollers is approximately adapted to the respective flange width to be guided of a steel profile.
  • the comparison of the flange guide pieces 8, 8 'in Fig. 5 and Fig. 7 also makes clear that an optimal flange guide is made possible by the flange guide pieces graded on the rolling program.
  • Fig. 8 it is shown that the flange guide pieces are formed as spacers which can be displaced between the roll chocks.
  • the rollers 13 and 14 together with the flange guide pieces 8 form a roller set which by means of a pair of wheels 15 on the rails 16 can be moved out of the scaffold.
  • the flange guide pieces 8 are arranged between the roll chocks 17 of the upper roll 13 and the roll chocks 18 of the lower roll 14 and keep the removed rolls at a distance.
  • Each flange guide piece is provided with an adjustment pin 19 which engages in an appropriately designed adjustment hole 20 which is let into the roller chocks 17, 18.
  • Each flange guide piece 8 is expediently narrower than the width B of the scaffold window 21 and, at least in the areas further away from the roller axis, dimensioned so high that the rollers 13, 14 mounted in the chocks 17, 18 are at a distance. In this way, the roller set shown in FIG. 8 as a complete unit can be quickly moved out of the roll stand 3 for the roller change.
  • the frame-side flange guide elements 9, 10 of a flange guide are connected according to FIG. 9 with hydraulically actuatable adjusting devices 23 and locked with the associated flange guide piece 8 to form a guide surface.
  • the flange guide piece 8 and the flange guide elements 9, 10 can be displaced by the adjusting devices 23 into the position shown in broken lines.
  • the stand-side flange guide elements 9, 10 are guided through the stand window 21 of the stand 24 of the roll stand 3 approximately transversely to the rolling line 22 and connected to a locking bar 25 to form a U-shaped cutout, the flange guide piece 8 being displaceable in this cutout and against an adjustment stop 27 , 28 is held lockable.
  • the locking bar 25 on the drive side 29 of the roll stand 3 is firmly connected to the flange guide elements 9, 10, for example by means of a welded connection 31.
  • the locking bar 26 on the operating side 30 of the roll stand 3 is detachably connected to the flange guide elements 9, 10.
  • the locking bar 26 is at the same time an integral part of the flange guide piece 8 via the connecting bolts 32.
  • the flange guide pieces 8 have the adjusting pins 19 on their upper side.
  • the flange guide pieces 8 are retracted with the aid of the adjusting devices 23 in the area of the roller chocks 17, 18 until the adjusting pins 19 of the flange guide pieces 8 face the adjustment bores 20 in the roller chocks and engage in them, so that the rollers 13, 14 are locked with their chocks 17, 18 to form a roller set. Then the flange guide pieces 8 are unlocked on the scaffold side by the hydraulic lock 34, for example a piston-cylinder unit, releasing the connecting bolts 33 on the drive side 29 and these being able to be pulled through the bores arranged in the locking bar 25.
  • the hydraulic lock 34 for example a piston-cylinder unit
  • the flanges guide piece 8 On the operating side 30 of the roll stand 3, the flanges guide piece 8 is unlocked on the stand side in that the hydraulic lock 35, for example a piston-cylinder unit, releases the locking bar 26 of the flange guide piece 8.
  • the flange guide pieces 8 now act as spacers for the roller set.
  • the entire set of rollers can then be moved out of the stand 3 through the stand window 21 using the pairs of wheels 15 running on the rails 16.
  • the removal and installation of the rolls, the roll change and the replacement and adaptation of the flange guide pieces / spacers adapted to the profile programs can be done much faster than before and largely be automated. Furthermore, a wide variety of steel profiles can be guided laterally in the roll stand with great certainty.
