Definitions

  • the invention relates to a device for changing the work and back-up rolls of a strip rolling mill, by means of a roll changing carriage which can be moved transversely to the roll stand, which takes up the pulled out old roll sets and enables exchange for new roll sets.
  • the known changing devices have the disadvantages that the construction effort for the creation of the device is very high, in particular because it is not infrequent that considerable foundation adjustments are also necessary.
  • the necessary cylinders and hydraulic motors often have to be supplied with energy via cable drag chains, which is relatively complex.
  • the object of the present invention is to design the device such that it is not only possible to change the backup rolls, but also to change the work rolls with the same backup roll changing cylinder.
  • an interchangeable cylinder which is fixed at the level of the hut, the piston rod of which can be extended and retracted transversely to the rolling stand.
  • a pull-out carriage which is arranged at the front end of the piston rod of the change cylinder, is displaceable on the roll changing carriage and can be coupled to it in such a way that the pull-out carriage, together with the roll changing carriage, can be moved transversely to the roll stand by the changing cylinder,
  • a transverse sliding table arranged in the roller changing carriage, which can be displaced transversely to the direction of movement of the roller changing carriage by means of a displacement cylinder independent of the roller changing carriage and through which the roller sets to be exchanged can be brought into or out of the changing position aligned with the center of the stand.
  • This solution according to the invention has a number of advantages.
  • all cylinders are arranged so that fixed piping is possible. This eliminates the usual cable drag chains. Only three cylinder units are required, namely for the roll changing cylinder, the cross slide table and the locking.
  • the roller changing carriage is in the waiting position shown in FIG. 1.
  • the roller change carriage 2 is below the change cylinder 4, which is shown with the piston rod 5 retracted.
  • a prepared new set of work rolls is located on the transverse shift table 6 next to the change cylinder 4.
  • a pull-out carriage 3 is arranged. This is - as shown in Figure 2, with the roll changer 2 through the piston rod in the direction of the roll stand move and connect automatically to the old work roll set 8. Subsequently, the connection between the pull-out carriage 3 and the roll changing carriage 2 is released and at the same time the roll changing carriage is locked by the transverse sliding cylinder 7 (FIG. 3).
  • the pull-out carriage 3 can pull the old roller set up to the cross slide table 6 by means of the exchangeable cylinder 4. There, the old work roll set is brought out and the new work roll set is brought into position (FIG. 4) by means of a corresponding transverse displacement by the cross slide cylinder 7, and then the new work roll set can be moved into the stand, as shown in FIGS. 5 and 6.
  • FIGS. 7 and 8 show the restoration of the starting point, that is to say the waiting position of the roller change carriage 2.
  • FIGS. 5 'to 16' show the further installation process, which is the opposite of the removal, and the return of the roller change carriage 2 to the waiting position or starting position.
