Definitions

  • the invention relates to a rolling block, in particular for finish rolling in high-speed wire-rolling mills, with a plurality of rolling units arranged one behind the other, alternately offset at right angles to one another, which are driven by two drive shafts running parallel to the rolling line on both sides, and with an upstream transfer case for driving the two drive shafts of one common drive motor with adjustable speed of the drive shafts.
  • the individual rolling units are driven by bevel gear drives or connections having a similar effect from the drive shafts.
  • the gear ratios correspond to the target speeds that result for the relevant rolling units from the caliber acceptance series that is decisive for the respective material qualities or the rolled product to be produced.
  • a certain speed ratio of the two drive shafts to one another is derived from this, to which these ratios are matched. If other materials are to be rolled or other rolled products are to be produced, the bevel gear and the speed ratio of the two drive shafts can remain unchanged. However, the speeds of the drive shafts have to be changed in accordance with the different operating requirements. Modified transfer cases must therefore be installed.
  • DE-A 2 446 905 already discloses the use of a controllable DC motor for changing the speed of the drive shafts.
  • the two drive shafts should each be driven at the same speed as one another. It is an object of the present invention to save the different transfer cases and their installation, also to avoid the use of a controllable direct current motor for mutually equal drive shaft speeds and rather to create a rolling block which is suitable for different rolling conditions and can be adapted to them by simply switching over.
  • the transfer case as a manual transmission for generating different speeds of the two drive shafts with the same speed ratio of the two drive shafts to one another
  • the manual transmission as a mechanical transmission with one input shaft and two drive shafts leading to the drive shafts and two over engaging and disengaging clutches is alternately operable gear arrangements and that two gears meshing with two gears arranged on the output shafts are arranged on the input shaft and that the gears assigned to one gear arrangement on the output shafts and the gear assigned to the other gear arrangement on the input shaft and one of the two gears meshing with it can be engaged and disengaged on an output shaft by means of a clutch.
  • the gearbox as a mechanical gearbox with an input shaft and two output shafts leading to the drive shafts and two gearwheel arrangements that can be operated alternately via engaging and disengaging clutches, two different drive shaft speeds are already achieved, i.e. the prerequisites for processing normal and stainless steel.
  • each of the two drive shafts of the transfer case driving the drive shafts is assigned a preferably hydraulic control gear.
  • this version enables the roller block to be operated with a large number of take-off rows.
  • an input shaft 1 driven by a motor, not shown, is equipped with two gear wheels 2 and 3.
  • the gear 3 is fixedly connected to the input shaft 1 via a feather key 4.
  • the gearwheel 2 is connected in a rotationally fixed manner to the input shaft 1 by means of a clutch 5.
  • the rotary connection can be released by disengaging the clutch 5 in the dot-dash position.
  • the two gears 2 and 3 are in engagement with gears 8 and 9, which are wedged onto intermediate shafts 6 and 7, which in turn have both gears on intermediate shafts 10 and Comb 11 splined gears 12 and 13 as well as gears 14 and 15 on an output shaft 16.
  • Both gears 14 and 15 are detachably connected to the output shaft 16 via a respective clutch 17 and 18.
  • Gears 19 and 20 on an output shaft 21 mesh with the gears 12 and 13.
  • the gear 19 is firmly wedged thereon.
  • the gear 20 is releasably connected to it via a clutch 22.
  • the two drive shafts (not shown) of the roll block which are connected to the output shafts 16 and 21, are driven from the input shaft 1 via the gearwheel arrangement 2, 8, 14, 12 and 19.
  • the clutch clutches 17 are engaged and the clutch clutches 18 and 22 disengaged.
  • the output shaft 18 receives a speed n u i, the output shaft 22 a speed n o i.
  • the resulting speeds of the individual roll lead, for example, to caliber reductions of 20 to 22% for the rolling of normal steel.
  • the motor drives an input shaft 23, which is equipped with two gears 24 and 25.
  • the gear 25 is wedged, the gear 24 releasable via a clutch 26.
  • the gear 24 meshes with the gears 27 and 29, the gear 25 with the gears 28 and 30 on the output shafts 31 and 32.
  • the gears 27, 28 and 30 can be engaged and disengaged by clutches 33, 34 and 35.
