Definitions

  • the invention relates to a roll stand with support and work rolls for rolling Sheets and strips, with the upper and lower work rolls together with the support rollers assigned to them by moving the horizontal in opposite directions each roller inside the stator window by means of between the chocks and the column stands of the roller stands Shift blocks via shift drives in pairs from the common Vertical plane can be moved into positions in which the through Cross the roller axes of the vertical and vertical rollers.
  • the known pair cross-rolling systems are very complex, they require usually special work roll bearings; the roller sets must go with Axial locks to be provided to the system-related inclination of the To be able to absorb occurring axial forces.
  • Another disadvantage is in it to see that adjustment components are arranged in the area of the scaffold guides hinder the roll change.
  • the object of the present invention is a generic Roll stand with little mechanical effort so that with simple Sliding drives and high system stability conventional bearings is possible, with the installation and removal of the work rolls is not hindered compared to conventional roll stands.
  • the invention proposes that the Sliding blocks are designed as U-shaped thrust pieces, the webs of which with their dome-shaped outer sides lie against the chocks and their legs the Grip the column of the roller stand on both sides.
  • the transverse bores of both legs of each pressure piece are preferably located opposite and are over a through the stand column of the roll stand Bore connected in which a common shaft connected to a rotary drive arranged for the eccentrics mounted on both sides in the transverse bores of the legs is.
  • the Support roller chocks to form as frame chocks that the Take up work roll chocks vertically adjustable, with the pressure pieces on fit the frame chocks.
  • This design means that Moving the sliding blocks both chocks, namely that of the backup roller and the work roll moved at the same time without the vertical adjustability of the
  • FIG 1 denotes the roll stand according to the invention, in which the upper Work roll 2a and the lower work roll 2b on both sides in upper chocks 3a and lower chocks 3b are stored.
  • the work rolls 2a, 2b are each supported by an upper support roller 4a and a lower support roller 4b, which in turn are stored in the upper chocks 5a and the lower chocks 5b.
  • the upper and lower chock 5a, 5b of each side is designed as a frame chock and engages with projections 6 the chocks 3a and 3b of the work rolls 2a and 2b from both sides, so that these inside the chocks 5a, 5b in the transverse direction are held.
  • the chocks 3a, 3b of the work rolls 2a, 2b adjustable are provided on both sides with side projections 7 provided, between which and the projections 6 of the chocks 5a, 5b vertically acting piston-cylinder units 8 are provided.
  • the chocks 5a, 5b are in the stator window 9 of the roller stand 1 arranged, as is known in conventional rolling stands.
  • the pressure pieces 10 are provided, which are U-shaped are and embrace the stand columns of the roll stand on both sides ( Figure 2).
  • the Outside of the webs of the pressure pieces 10 are, as indicated at 12, dome-shaped trained and lie laterally on the chocks 5a, 5b.
  • cross holes 13 are made in which the arranged on the roll stand 1 to the axes 14 of the transverse bores 13th parallel axes 15 rotatable eccentric 16 are mounted.
  • the components described are in cross section through the roll stand according to FIG easier to see.
  • the pillars 1 1 are pierced in the transverse direction; through the A shaft 17 is guided through the bore, on both sides of the column columns 1 1
  • Eccentric 16 are attached.
  • the eccentrics 16 sit in the transverse bores 13 and cause over rotation of the common shaft 17 and thus the eccentric 16 the overall drive designated as 18 a displacement of the U-shaped Thrust pieces 1 0 transverse to the roller axis 19, so that the chocks 5a (in the Drawing level to the right or left), whereby the dome-shaped outer sides 12 an inclination of the chocks relative to the Allow pressure pieces 1 0 and the pillars 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, via a Computer program, setting the work and backup rolls in pairs the opposite work and back-up rolls in various variations is possible.
