Definitions

  • the invention relates to a device for oiling strip-like or sheet-like sheets with a housing having an inlet and an outlet for the sheet-metal passage, in which nozzles for spraying the oil, which are arranged transversely to the direction of strip travel, and distribution rollers arranged downstream of the nozzles in the direction of passage are provided .
  • the desired, uniform, thin oil film on the surface of the sheet to be oiled cannot be ensured via the nozzles alone.
  • Distribution rollers are therefore arranged downstream of the nozzles, which are to ensure an even distribution of the sprayed oil.
  • the uniformity of the oil film also depends on whether a good distribution of the oil over the surface of the sheet can already be achieved via the nozzles. It has been found that with a comparatively good oil distribution using the nozzles, the uniformity of the applied film layer could not be decisively improved by the downstream distributor rollers, so that certain limits were set for the uniformity, in particular of very thin oil films.
  • the invention is therefore based on the object to avoid these deficiencies and to improve a device of the type described in such a way that a higher accuracy when applying thin oil films on the sheet metal surfaces can be ensured.
  • the invention solves the problem in that the housing two arranged one behind the other in the direction of passage of the sheets, substantially against each other has sealed chambers on the one hand for the nozzles and on the other hand for the distributor rollers.
  • the distributor rollers By arranging the distributor rollers in a chamber that is essentially sealed off from the spray cones of the nozzles, a particularly high uniformity of thin oil films on the sheet metal surfaces can be surprisingly ensured, namely because the air vortices caused by the rotating distributor rollers ensure the uniform formation of the spray cones cannot interfere with the nozzles.
  • the provision of the nozzles and the distributor rollers in separate chambers thus enables a more uniform oil distribution on the sheet metal surface through the nozzles, which inevitably leads to a better result because the distributor rollers no longer have to compensate for the irregularities caused by them. This results in a significant increase in quality with simple means.
  • the sheet 1 to be oiled is passed through a housing 2 which is provided with an inlet 3 and an outlet 4 for the sheet passage.
  • the housing 2 is divided into two chambers 6 and 7, which are located one behind the other / the direction of passage of the sheet 1.
  • the front chamber 6 above and below the sheet 1, there are a plurality of nozzles 8, which are distributed transversely to the direction of strip travel and for spraying an oil which strikes the sheet surface in the form of spray cones 9.
  • two distributor rollers 10 are provided, which have a wear-resistant, non-absorbent plastic jacket 11 and are mounted in rockers 12, between which a tensioning cylinder, not shown, is articulated in order to ensure a corresponding contact pressure on the sheet metal strip passed between the two distributor rollers 10 .
  • nozzles 8 are supplied with the oil by means of piston pumps, spray intervals result which have to be matched to the throughput speed of the sheet.
  • the piston pumps are driven depending on the belt speed.
  • These spray intervals can lead to uneven oil distribution if care is not taken to ensure that the circumference of the distributor rollers is not an integral multiple of the distance between the spray spots on the sheet. If the circumference of the distributor rollers were to be an integer multiple of the spray spot distance in the direction of travel, the same circumferential area of the distributor rollers would always come into contact with the spray spots, so that no uniform oil distribution around the roller circumference would be possible.
