Definitions

  • the invention relates to a bending block for bending the rolls of multi-roll stands, which on both sides of the bearing chocks of the pair of rolls to be bent firmly connected to the window pillars of the roll stand or with devices for horizontal stabilization of the rolls, in both bending directions guided slidably, driven by piston-cylinder units bending jaws , which act on the bearing chocks or the devices with pressure bearing surfaces assigned to one or the other bending direction.
  • the invention has for its object to eliminate these drawbacks and to create the possibility of a virtually play-free interaction of the bending jaws with the bearing chocks.
  • each bending jaw consists of a pair of independent, oppositely drivable partial bending jaws, the pressure bearing surfaces of which are assigned to one or the other bending direction.
  • the invention is applicable to all forms of training of two and multi-roll stands, including those with axially displaceable rolls.
  • the one partial bending jaw can have a cube-shaped or cuboid-shaped housing that is guided with flat contact sliding surfaces between counter-contact sliding surfaces of the housing of the other partial bending jaw.
  • the housing of the others Part-bending jaw can consist of two spaced-apart, the housing of one part-bending jaw leading between them, connected to each other by a cross member housing sections.
  • the piston cylinder unit which drives the corresponding partial bending jaws for the upper or lower roller of the pair of rollers to be bent can each consist of a piston cylinder unit in one partial bending jaw and connecting rods to the other partial bending jaw.
  • the bending blocks 7 and 8 fixedly connected to the window bars 1 and 2, are arranged in the window bars 1 and 2 of the roll stand, on both sides of the pair of work rolls 5, 6 acted upon by the support rolls 3 and 4.
  • pairs of partial bending jaws 11a, 11b or 12a, 12b and 13a, 13b or 14a, 14b are guided vertically one above the other (see also FIGS. 2, 3, 4 and 5).
  • the partial bending jaws 13a, 13b assigned to the upper bearing insert 9 of a pair of partial bending jaws are coupled to the partial bending jaws 14a, 14b arranged below and assigned to the bearing insert 10 (see FIGS. 4 and 5) and are cylinder housings of piston-cylinder units, the pistons 16 of which and 19 are coupled to one another by common connecting rods 17 and 20 (see FIG. 4).
  • the housings of the partial bending jaws 13a, 13b are of cubic design, the housing of the partial bending jaw 13a consisting of two housings arranged at a distance from one another, between which the housing of the other partial bending jaw 13b can slide is performed (see FIG. 3).
  • the two housings of the partial bending jaw 13a are possibly connected in one piece by a cross member 21.
  • the bearing chocks 5, 6 facing stop bars ( Figure 1) 11a, 11b; 12a, 12b; 13a, 13b; 14a, 14b, which with their pressure bearing surfaces are able to act on the pressure receiving surfaces of stop lugs 9a, 9b and 10a, 10b arranged on the bearing chocks 9 and 10, respectively, when the respective partial bending jaws 11a, 11b; 12a, 12b; 13a, 13b; 14a, 14b are moved towards each other when the pistons 16 and 19 are actuated.
  • Figure 1 the illustration according to FIG. 1 in conjunction with FIG.
  • the stop bar 13a 'of the partial bending jaw 13a and the stop bar 13b' of the partial bending jaw 13b move towards one another in the direction of the arrows shown in FIG. 4 and detect them assigned stop lug 9b of the bearing chock 9 between them like pliers.
  • the desired pressure from above or from below can now be applied without play to the stop lug 9b and thus to the bearing chock 9, likewise to the other stop lugs 9a, 10a and 10b.
  • the work rolls 5, 6 are removed by pulling them out of separate guides and over the partial bending jaws (see Fig. 1).
  • the lower chock 10 slides with its stop lugs 10a and 10b on the stop bars 12a 'and 14a'
  • the upper chock 9 slides with additional removal lugs 9a 'and 9b' on the stop bars 11a 'and 13a'.
  • the work rolls 5, 6 can also be pulled out on the stop lugs 9a and 9b.
  • Fig. 2 From Fig. 2 it can be seen that the piston 22 is arranged with the piston rod 23 for balancing the chock 24 of the support roller in the housing of the bending block 8.
