Definitions

  • the invention relates to a compact rolling block arrangement for rolling, side by side from a preprocessing system in parallel lines
  • Rolled material strands in which the billets alternate in the rolling direction subsequently have vertical or horizontal roller pairs, which are connected via angular gears coupled with drive shafts running parallel to the rolling lines are.
  • the invention has for its object a roll block assembly with the Drive shafts and the connecting elements that create this tight Installation ratio takes into account.
  • This object is achieved in that three jointly driven drive shafts for the rolls, positioned in relation to one another in the axial direction, that the center of the axis of one of the drive shafts in the upper corner of an upright, isosceles triangle and the center of the axles of the other two drive shafts lie in the two lower corners of this triangle.
  • the invention further provides, having the horizontal roller pairs Roll blocks to be coupled to the drive shaft, the center of its axis in the the upper corner point of the triangle and the vertical roller pairs Rolling blocks to be coupled to the drive shafts, the axes of which in the two lower corner points of the triangle.
  • the ones exhibiting pairs of horizontal wafers Rolling blocks are useful to down their drive shaft axis inclined and the roll blocks having vertical roll pairs around their drive shaft axis arranged inclined outwards.
  • the arrangement can be according to the invention so that the two drive shafts, the center of their axes lie in the two outer corner points of the isosceles triangle, each with an equal number of billets with pairs of horizontal rolls are connected to the drive and the drive shafts, the center of which is in the upper Corner point of the triangle is twice that number of rams, these blocks with their horizontal roller pairs alternately one and the other of the two rolling lines are assigned.
  • the drive shafts of the Roll blocks as the invention further proposes, together by one Motor driven, the three drive shafts each having a spur gear, the combs with a spur wheel sitting on the motor shaft.
  • the axis centers of the upper Drive shaft and that of the two lower drive shafts and the center lines the wire strands can be positioned according to the invention so that they in the Corners of an even pentagon run.
  • the rolling block arrangement according to FIG. 1 for two horizontal parallel rolling lines L1, L2 shows three drive shafts 2, 3, 4 in the tips of an isosceles triangle lying, of which the two lower drive shafts 3, 4 vertical blocks VL; Drive VR that are inclined outwards and the upper drive shaft 2 horizontal rolling blocks OL, OR drives, which alternate in opposite directions are arranged inclined downwards, the roller pairs RR all at right angles lie in the two rolling lines L1, L2.
  • Figure 4 shows a single motor M with motor axis 1, which the axis movement by means of a gear transmission 11 ( Figure 1 and Figure 3) in three gears 21, 31, 41 transmits, which is arranged in the shape of an isosceles triangle and each sit on the drive shafts 2, 3, 4, each with rolling blocks OR, VR, VL are coupled, each roll block having a pair of head rolls, via intermediate gears c1 and c2 from the respective drive shafts 2, 3, 4 is driven, with two of the drive shafts 3 and 4 being at the height of the Base angle of the isosceles triangle mentioned above and the third wave 2 is at the top of the isosceles triangle, where the two drive shafts 3, 4 the respective blocks VR and VL on the right and the left side with the roller pairs RR for vertical rolling drive VRR right and left up, and with the upper drive shaft 2 alternately a roll block OR to the right and a roll block OL to the left with the corresponding pair of top rollers RR for horizontal rolling ORR drives, the positioning of the drive shaft
  • the block arrangement is strongly compacted in this way and has an equal number of vertical billets (in the case shown three) on the right VR and the left VL side at the lower drive shafts 3, 4 on. During two times three roll stands on the upper drive shaft 2, respectively half arranged on the left side OL and half on the right side R. are.
  • Figure 1 shows, in vertical cross section, a structure in the form of an isosceles Pentagon.
