Definitions

  • the invention relates to a wire rolling mill in block form, so-called.
  • Wire block with at least one driven longitudinal shaft, from which transverse shafts for driving the scaffolding are branched off via bevel gear transmissions, the driving bevel gears being freely rotatably mounted on the longitudinal shaft and selectively couplable to the longitudinal shaft via clutch couplings.
  • Such a wire rolling mill is described in DE-OS 24 46 905 and has the advantage of being able to additively switch off scaffolding or rolling disks from the outlet side, regardless of an increased speed of the longitudinal shaft when rolling larger cross sections, vibration problems in the area of the unneeded roller drives turn off.
  • the invention is therefore based on the object of avoiding impact markings on switched off branch drives for scaffolding points or rolling disks.
  • the solution to this problem is that the driving bevel gears, which are loosely mounted on the longitudinal shaft, can be driven by slow-running auxiliary drives, each of which comprises a driving wheel which, by axial movement, comes into drive connection with the associated bevel gear, with a fuse being provided, which prevents the axial movement of the slow-running driving wheel when the associated clutch for the driving bevel gear is closed, and which prevents the clutch from engaging when the slow-running driving wheel is in drive connection with the bevel gear.
  • the bevel gear stage and the transverse shafts of a scaffolding point or a pair of roller disks constantly rotate slowly when they are uncoupled from the longitudinal shaft.
  • the slow-running drive wheels are also bevel gears, which come into engagement with the associated bevel gear on the longitudinal shaft by axial movement.
  • the slow-running drive wheels are each designed as overhung, bevel gear-like friction wheels, the drive shafts of which extend transversely to the longitudinal shaft and are axially adjustable away from the bevel gear against a sustained force.
  • a preferred further embodiment of the slow-running auxiliary drive is specified in claims 3 and 4.
  • the backup for the mutual locking of the coupling processes of both the slow-running driving wheel and the clutch consists of the fact that the shift lever of the clutch and that of the auxiliary drive are connected to each other, so that the two coupling processes inevitably go in the opposite sense.
  • the wire block comprises a housing 1 with a longitudinal shaft 4 mounted therein, which is driven on the outlet side by an adjustable DC motor (not shown) via a countershaft transmission 2.
  • an adjustable DC motor not shown
  • a countershaft transmission 2 On the longitudinal shaft 4, freely rotatable bevel gears 5, 6 are mounted, which are in constant engagement with driven bevel gears 7 and 8.
  • Transverse shafts 9 and 10 are driven by the bevel gears 7 and 8 and carry upper rolling disks 11 and 12 at their ends.
  • the roller disks located below each sit on further invisible transverse shafts which are coupled to one another via opposing comb rollers 13 and 14.
  • Rotating shift sleeves 16, 17 are provided on the longitudinal shaft 4 and can be displaced via the hand levers 18, 19 on the longitudinal shaft 4 provided with a multi-groove toothing.
  • Each shift sleeve 16, 17 has an internal toothing, for. B. 17a, which can be brought into and out of engagement with an external toothing 6a of the bevel gears 5 and 6 respectively. It can be seen that the shift sleeve 17 is disengaged, with which the associated bevel gear 6 is uncoupled and the stand with the roller plate 12 is switched off. The shift sleeve 16, however, is engaged and rotates the bevel gear 5, so that the stand with the roller plate 11 is in operation.
  • the auxiliary drive 21 is thus able to slowly rotate the disengaged and freely rotatable bevel gear 6.
  • the shift levers 18 and 19 are connected via coupling rods 25 to the shift levers 26, 27 of the additional drives 20, 21 such that with the engagement of, for example, the shift sleeve 16, the friction wheel 22 is lifted off the conical counter surface 5a of the bevel gear 5 and, conversely, can only be made to make frictional contact when the shift sleeve is uncoupled from the bevel gear, which applies to the shift sleeve 17 and the friction wheel 23.
  • the slow-running drive wheel of the additional drive 20 is designed as a cantilever-like friction wheel 22 which is mounted on the fly and which is seated on a drive shaft 30 which extends transversely to the longitudinal shaft 4.
  • the drive shaft 30 has a longitudinally toothed end 30a which engages in an internally toothed bush 31 which is driven by a hydraulic motor 32.
  • the hydraulic motor is flanged to a housing cover 33, which closes a cylindrical housing 34 with a cylindrical outer sleeve 35.
  • the drive shaft 30 is mounted within a two-part, axially adjustable bushing 36, 37, the upper part 37 of the bushing carrying a collar 37a as an abutment for a compression spring 38 which is supported on the housing cover 33.
  • a positioning eccentric 39 of an adjusting shaft 40 which is transverse to the axial direction of adjustment of the drive shaft 30 in the housing jacket, is used for the axial adjustment of the bush 36, 37, which is secured against rotation, along with the drive shaft 30 34 stored and adjustable by the hand lever 26.
