Definitions

  • the invention relates to a rolling stand for a rolling mill for rolling rod material, in particular made of high-alloy steels or superalloys, with a worm gear mechanism and exchangeable roller housing, the pair of rollers mounted in the roller housing being able to be coupled to the output shafts of the comb roller gear via couplings consisting of parts which can be pulled off one another.
  • the starting material is rolled out in several passes according to the pass schedule to the desired final cross-section, and it is known to carry out all these passes one after the other in a rolling train which consists of a plurality of rolling stands adapted to the pass schedule.
  • DE-B-1 145124 shows, it has already been proposed to connect either a horizontal pair of rollers or a vertical pair of rollers to a reduction gear via a common coupling point, but this requires the replacement of the entire horizontal or vertical stand including rollers and associated comb rollers, Articulated spindles, gears and. The like. Requires and in turn only allows the use of one and the same roller dimension.
  • the invention is therefore based on the object to eliminate these deficiencies and to create a rolling stand of the type described, which is characterized by the possibility of simple adaptation to a wide variety of rolling programs and, above all, allows the installation of a rolling mill in a small space and without great effort , which ensures economical rolling of rod material, especially from high-alloy steels, in a wide range of dimensions.
  • the comb roller gearbox has at least one other roller housing with a bale and pin diameter in a smaller cross-sectional area of the rod material to be rolled designed rollers listened to, which instead of the former roller housing while maintaining its rolling center can be connected to the worm gear mechanism using an intermediate gear adapted to the changed roller dimensions, which intermediate gear carries a coupling part on the input side for connection to one of the output shafts of the comb roller gearbox, with the part seated on this output shaft the coupling used for the roller housing connection cooperates, preferably also for the drive connection of the intermediate gear and the additional roller housing, couplings made of removable Te are provided.
  • these additional roller housings allow the rolling mill to be converted to other roller dimensions and thus a change in the rollable cross-sectional area.
  • a comparatively small rolling mill with a few rolling stands is therefore sufficient to be able to roll bar material in practically any cross-sectional size in one or more passes, with the roll housings merely having to be replaced by the additional roll housings or the additional roll housings already fitted by correspondingly additional new roll housings after each rolling pass .
  • the additional roller housings are equipped with graduated rollers for the individual runs, which define a constant rolling axis and whose speed is matched to the same throughput speeds, so that the best rolling conditions can be achieved for each cross-section.
  • the intermediate gear for the drive connection of the additional roller housing and the comb roller gear can easily bridge the distance between the comb roller gear and the additional roller housing caused by the different roller dimensions and the remaining roller center, and at the same time the drive speeds can be adapted to these dimensional differences.
  • the intermediate gear is preferably detachable from the additional roller housing, but can also be combined with this to form a structural unit.
  • Roll stands according to AT-B-370 643 have already proven themselves due to their compact design and the possibility of efficient roll changes and are also ideally suited for use in the rolling mills according to the invention.
  • the additional roller housing corresponding to the roller housing, can be placed with a bearing jaw on the outer bearing journal and can be pivoted from a change position into a tight fitting position on the comb roller transmission including the intermediate transmission, and vice versa, the intermediate transmission itself being supported with a bearing jaw on an inner bearing journal of the comb roller transmission .
  • the additional roller housing and also the intermediate gear can be assembled and disassembled quickly and easily, whereby the additional roller housing for the comb roller gear also functions as a gear cover and the closed structural unit with all its advantages in terms of gear termination, clutch arrangement, lubrication conditions and the like. The like is preserved.
  • Figure 1 and Figure 2 each in section a roll stand with attached roller housing or with attached additional roller housing.
  • the mill stand designated as a whole by 1, has a comb roller gear 2 with two output shafts 3 for the roller drive and forms an end wall 4 on the roller side for the tight attachment of a roller housing receiving the rollers, an outer bearing journal 5 and a hydraulic quick-action clamping device for supporting and fastening this roller housing 6 are provided.
  • a cassette-shaped roller housing 7 is seated on the worm gear 2, which is supported on the bearing journal 5 via a bearing jaw 8 and is fastened sealingly but releasably to the end wall 4 by means of the quick-action clamping device 6.
  • a roller pair 9 is supported in the roller housing 7, with eccentric bushes 11, 12 for the roller bearings, which can be rotated by means of an adjustment drive 10, allowing the roller pair 9 to be adjusted radially.
  • Oldham couplings 13 are used for the drive connection between the roller pair 9 and the output shafts 3 of the comb roller transmission 2, which consist of parts 13 ′, 13 ′′ which can be pulled off one another and which not only bring about the required torque transmission, but also compensate for the transverse offset caused by the adjustment of the roller pair 9 .
  • the comb roller gear 2 is assigned a smaller-sized additional roller housing 7 ', which is placed on the comb roller gear 2 instead of the roller housing 7 with the interposition of an intermediate gear 14 leaves.
  • This additional roller housing 7 ' is constructed on a cover plate 7 "which is adapted to the end wall 4 and which likewise has a bearing jaw 8' for the bearing journal 5 and can be fixed by means of the quick-release device 6.
  • the additional roller housing 7 ' takes a pair of rollers which is smaller than the pair of rollers 9 9 ', which for radial adjustability is supported in eccentric bushes 11', 12 'which are rotatably adjustable via an adjustment drive 10'.
  • the center of the roll of the pair of rolls 9 'always corresponds exactly to the center of the roll determined by the pair of rolls 9 of the roll housing 7.
  • an intermediate gear 14 is interposed, which is supported by a bearing jaw 15 on an inner journal 16 of the comb roller gear 2 and within the space created by the end wall 4 Finds space ischenantrieb 14 has two output shafts 3 'to which the pair of rollers 9' via Oldham couplings 17 from parts 17 'which can be pulled off one another. 17 ".
  • the intermediate gear 14 For connection to one of the output shafts 3 of the worm gear 2, the intermediate gear 14 carries on the input side a coupling part 13" 'which interacts with the part 13' of the Oldham coupling 13 for the roller housing 9 remaining on this output shaft 3 and the drive derived from the worm gear.
  • roller housing 9 The assignment of two or more roller housings to a common worm gear be allows a rational and low-effort adaptation of the rolling stands to the most diverse rolling dimensions, so that, for example, with a short rolling train from these rolling stands, several rolling passes are possible and large dimensional ranges can be rolled on a small system.
