Definitions

  • the invention relates to a rolling mill with an adjustable nip for ceramic masses according to the preamble of claim 1.
  • Such rolling mills have been known and used for many years.
  • a problem with such rolling mills is the exact setting and fixing of the roll gap. As a result of uneven wear of the roller surfaces and possible non-parallel turning of the rollers when the roller surfaces have to be smoothed, it is hardly possible to maintain a constant nip across the entire width of the rollers in previous rolling mills. Furthermore, in the conventional rolling mills, an adjustment or fixation of the roll gap, generally using spacers to be inserted or exchanged by hand, can only take place when the rolling mill is at a standstill.
  • the object of the present invention is therefore to design the known rolling mills in such a way that an exact setting and fixing of the nip is possible over the entire width of the roller, in a simple and quick manner and also when the rolling mill is running.
  • the solution to this problem results from the characterizing features of patent claim 1.
  • 10 denotes a machine stand on which the two rolling mill rollers 11 and 12 are mounted.
  • the axis 11a of the roller 11 is mounted directly in lugs 10a of the machine stand 10 on both sides: this roller is therefore referred to as the fixed roller.
  • the axis 12a of the In contrast, roller 12 is supported on both sides on rockers 14 which can be pivoted relative to the machine stand 10; the roller 12 is therefore referred to as an adjusting roller.
  • the rockers 14 in turn are pivotally mounted on stub axles 15 of the machine stand 10 and are designed in the manner of a two-arm lever.
  • the free end of one lever arm is supported by a spindle lifting element 16, the free end of the other lever arm by a hydraulic piston-cylinder unit 17.
  • the axis 12a of the adjusting roller 12 is also mounted on the rockers.
  • a lathe movable on the machine stand 10 is indicated for turning off the adjusting roller 12.
  • 19 designates a hydraulic unit with pumps, display elements and control buttons 20.
  • the rockers 14 are loaded by the piston-cylinder units 17 in the upward direction, with a hydraulic pressure predetermined by the hydraulic unit 19.
  • the height of the spindle lifting elements 16 can be adjusted separately, either manually or by motor.
  • the height of the elements 16 defines the width of the roll gap a, the gap being wider the higher the elements 16 are set. Because the two spindle lifting elements 16 are separately adjustable, the parallelism of the roller gap a over the entire roller width b can also be ensured if, for example, one of the rollers has been turned non-parallel, for example the roller 12 by the lathe 18.
  • the hydraulic pressure in the piston-cylinder units 17 is dimensioned such that, in normal operation, the rockers 14 are pressed firmly against the spindle lifting elements 16, but when a hard foreign body penetrates into the roll gap, the back pressure caused by this foreign body overcomes the hydraulic pressure of the elements 17 , with the result of an opening of the roller gap (protection of the hard roller surface). As soon as the stranger the body has "failed" downwards, the nip closes again automatically to its set value.
  • the adjustment of the roll gap can obviously be carried out manually or by motor without having to stop the rolling mill.
