Definitions

  • the invention relates to a roll stand with support and work rolls for the rolling of sheets and strips, in which the upper and lower work rolls together with the support rolls assigned to them by counter-horizontal displacement of the chocks stored within the stator window by means of between the chocks and the stator columns Roller stands arranged displacement blocks can be moved in pairs from the common vertical plane into positions in which the vertical planes running through the roller axes of the work and backup rollers intersect.
  • the known pair cross-rolling systems are very complex, they require usually special work roll bearings;
  • the roller sets must be provided with axial locks in order to be able to absorb the axial forces caused by the system-related inclination of the rollers.
  • Another disadvantage is the fact that adjustment components are arranged in the area of the scaffold guides that hinder the roller change.
  • the object of the present invention is to design a roll stand of the generic type with little mechanical outlay in such a way that, with simple displacement drives and high system stability, the rolls can be entangled with conventional ones Storage is possible, whereby the installation and removal of the work rolls is not hindered compared to conventional roll stands.
  • the displacement blocks are designed as U-shaped pressure pieces, the webs of which rest with their spherical-shaped outer sides on the chocks and whose legs encompass the column of the roll stand on both sides.
  • the U-shaped pressure pieces that comprise the roller stand create an extremely stable construction, in which the guides are arranged on the side of the stand columns of the roller stand, that is to say they are moved outward from the area of the stand window.
  • the part of the pressure piece which is arranged within the stator window is very narrow, as a result of which the chocks can be very large.
  • the outer sides of the pressure pieces, which face the chocks are dome-shaped, so that an inclination of the rollers in these dome-shaped parts can be absorbed easily and with little wear even under high forces.
  • transverse bores are provided for displacing the pressure pieces in their two legs encompassing the stator column of the roller stand, in which eccentric axes which are rotatable on the roller stand and are parallel to the axes of the transverse bores are mounted.
  • the transverse bores of both legs of each pressure piece preferably lie opposite one another and are connected via a bore penetrating the column of the roller stand, in which a common shaft connected to a rotary drive is arranged for the eccentrics mounted on both sides in the transverse bores of the legs.
  • the support roller chocks are designed as frame chocks which accommodate the work roll chocks in a vertically adjustable manner, the pressure pieces abutting the frame chocks.
  • the construction of the roll stand according to the invention results in significant advantages over the prior art.
  • a low mechanical effort for the interlacing of the rollers by electrically synchronized single drives of the eccentric adjustments and simple maintenance on the external drives are to be emphasized.
  • the transfer of the hodzontal forces over large dimensioned dome-shaped pressure surfaces on the chocks has already been mentioned.
  • the adjustability by means of eccentrics makes it possible to wear out to compensate for the calottes without worsening the adjustment accuracy of the overall system.
  • the design of the work rolls, chocks and bearings as in conventional rolling mills simplifies the system and enables a quick change of work.
  • the roll stand according to the invention is designated by 1, in which the upper work roll 2a and the lower work roll 2b are supported on both sides in upper chocks 3a and lower chocks 3b.
  • the work rolls 2a, 2b are each supported by an upper support roll 4a and a lower support roll 4b, which in turn are supported in the upper chocks 5a and the lower chocks 5b.
  • the upper and lower chocks 5a, 5b of each side is designed as a frame chock and overlaps with projections 6 the chocks 3a and 3b of the work rolls 2a and 2b from both sides, so that they are held in the chocks 5a, 5b in the transverse direction.
  • the chocks 3a, 3b of the work rolls 2a, 2b are adjustable in the vertical direction; for this purpose, the chocks 3a, 3b are provided on both sides with lateral projections 7, between which and the projections 6 of the chocks 5a, 5b vertically acting piston-cylinder units 8 are provided.
  • the chocks 5a, 5b are arranged in the stand window 9 of the roll stand 1, as is known in conventional roll stands.
  • the pressure pieces 10 are provided on both sides of the chocks 5a, 5b, which are U-shaped and encompass the stand columns of the roller stand on both sides (FIG. 2).
  • the outer sides of the webs of the pressure pieces 10 are, as indicated at 12, dome-shaped and lie laterally on the chocks 5a, 5b.
  • transverse bores 13 In the legs of the pressure pieces 10 there are transverse bores 13 in which the eccentrics 16 which are arranged on the roller stand 1 and are rotatable about axes 15 parallel to the axes 14 of the transverse bores 13 are mounted.
  • the components described can be better seen in the cross section through the roll stand according to FIG.
  • the pillars 1 1 are pierced in the transverse direction; a shaft 17 is guided through the bore, on which the eccentrics 16 are fastened on both sides of the support columns 11.
  • the eccentrics 16 sit in the transverse bores 13 and, when the common shaft 17 and thus the eccentric 16 are rotated, cause the U-shaped pressure pieces 10 to be displaced transversely to the roller axis 19 via the rotary drive designated as 18, so that the chocks 5a (in the plane of the drawing) to the right or left) can be shifted, the dome-shaped outer sides 12 allowing the chocks to be inclined relative to the pressure pieces 1 0 and the upright columns 1 1.
  • the drive 18 consists of the electric motor 20 and the spur and planetary gears 21, 22, which are attached to each pressure piece 1 0.
  • the drives of the individual pressure pieces are electrically synchronized with one another, so that, if necessary, a variety of variations can be set in pairs to the opposite work and support rolls via a computer program.
