Definitions

  • the invention relates to a device for guiding rotating about its longitudinal axis blanks emerging from a cross rolling mill, in particular woodlice mill.
  • Such a device is known from JP-A-57072708.
  • JP-A-59078705 is a device for guiding around its longitudinal axis rotating blanks known in a rolling mill, with the other features the preamble of claim 1.
  • the basic idea of the present invention is accordingly to provide a continuous rotating tubular guide for the run-out billet, which ensures that the spirally-outgoing billet leaves the rolling mill as freely as possible, but with optimal guidance.
  • the continuous guide rollers can easily accommodate fluctuations in the diameter of the outgoing billet, and the rotating guide rolls reliably prevent twisting in thin-walled long billets.
  • the guide rollers are each mounted on the end face, as is already practiced with roller cooling beds, for example.
  • the guide rollers are also at intervals by below it arranged rotatably supported support rollers.
  • tubular guide rollers and / or the support rollers by on Run-out speed synchronized drives can be driven in rotation. Thereby torsional forces acting on the plate are avoided.
  • the slab can be spread evenly on both Guide rollers rest and are supported by them at the outlet.
  • the Guide rollers on inclined, symmetrical to the center of the roll Adjustable guide carriage.
  • This slide can adjust the height and the distance at the same time the guide rollers vary from each other, so that strong in diameter different troops can be safely guided.
  • This Guide rollers prevent the leaking slug from breaking out of the side Rest on the tubular guide rollers.
  • each around a horizontal and transverse Axis extending to the hole outlet direction can be driven in rotation.
  • This Disc rollers become after the upper short guide rollers are swung away swung in from below and lift the slab off the tubular guide rollers from to to them in a known manner on the circumferential grooves of the disc rollers Transport transfer position to a removal device. After that the finished rolled billet in a known manner, for example via a pivot lever ejected.
  • the present invention provides an optimal guiding device for the spiral leaking slugs and is particularly favorable for thin-walled slugs used. With these thin-walled blanks, the risk of twisting in conventional guideways can be safely avoided, a danger of Buckling of the slug is achieved by using the continuous guide no more.
  • the spirally tapering cap 1 is made up of two lower ones preferably offset by 30 ° from the horizontal outlet plane Guide rollers 2 out.
  • the guide rollers 2 are over the maximum to be rolled Bead length (e.g. 15 m) designed as a continuous guide tube.
  • To support the guide rollers 2 are in corresponding Intervals lower support rollers 4 attached. If necessary, the tubular Guide rollers 2 with a synchronized to the outlet speed of the die 1 Drive are driven.
  • the dimension-dependent setting of the tubular Guide rollers 2 take place centrally to the center of the roll individually via correspondingly inclined ones Guide carriage 5 or together with smaller diameter differences an outside pivot.
  • the upper short guide rollers 6 are swung out, and in a position shown at 6.1.
  • the between the tubular Guide rollers 2 arranged driven disc rollers 7 are used for Longitudinal transport of the slug 1 is restricted, whereby the slug is lifted and into a Transfer position is transported. There the finished roll 1 is over a pivotable lever 8 ejected laterally.

Claims (6)

  1. Dispositif pour guider des loupes sortant en tournant autour de leur axe longitudinal d'un laminoir à cylindres obliques, en particulier un laminoir Assel, au moyen d'au moins deux rouleaux de guidage (2) s'étendant sur toute la longueur maximale de la loupe, lesquels sont agencés en étant montés en pouvant tourner autour de leurs axes longitudinaux l'un à côté de l'autre parallèlement à la direction de sortie de la loupe au-dessous du plan de sortie de la loupe (1),
    caractérisé en ce que les rouleaux de guidage (2) sont réalisés de façon tubulaire et sont montés, à chaque fois, du côté frontal, et en ce que les rouleaux de guidage (2) sont supportés, à intervalles, par des rouleaux d'appui (4) montés de façon rotative agencés au-dessous de ceux-ci, les rouleaux de guidage tubulaires (2) et/ou les rouleaux d'appui (4) pouvant être entraínés en rotation par des entraínements synchronisés à la vitesse de rotation de sortie de la loupe.
  2. Dispositif selon la revendication 1,
    caractérisé en ce que, dans le cas de deux rouleaux de guidage tubulaires (2), ceux-ci sont agencés des deux côtés au-dessous de la loupe (1) en étant décalés de 30° du plan de sortie horizontal.
  3. Dispositif selon une des revendications 1 à 2,
    caractérisé en ce que, pour régler la position des rouleaux de guidage tubulaires (2) à différentes dimensions de loupe, les rouleaux de guidage (2) sont montés de façon réglable sur des chariots de guidage (5) inclinés, agencés de façon symétrique par rapport au centre de laminage.
  4. Dispositif selon une des revendications 1 à 3,
    caractérisé en ce que, pour régler la position des rouleaux de guidage tubulaires (2) à différentes dimensions de loupe, les rouleaux de guidage (2) peuvent être pivotés en commun autour d'un pivot central.
  5. Dispositif selon une des revendications 1 à 4,
    caractérisé en ce que, au-dessus des rouleaux de guidage tubulaires (2), verticalement au-dessus de la loupe (1), sont prévus plusieurs courts rouleaux de guidage (6) pouvant être appliqués contre l'enveloppe de la loupe et pouvant pivoter (6.1) en commun pour éjecter la loupe (1).
  6. Dispositif selon une des revendications 1 à 5,
    caractérisé en ce que, pour l'évacuation de la loupe laminée (1), entre les deux rouleaux de guidage tubulaires inférieurs (2), sont prévus des disques (7) pouvant être soulevés et abaissés qui, à chaque fois, peuvent être entraínés en rotation autour d'un axe horizontal et s'étendant transversalement à la direction de sortie de la loupe.
