Definitions
- the invention relates to a device for dewatering a metal strip, facilitated maintenance.
- the field of the invention is that of cold rolling for which it is necessary to project on the strip to roll large volumes of a liquid, consisting of an oil or an emulsion in water, to ensure the lubrication and cooling of the belt and cylinders.
- a liquid consisting of an oil or an emulsion in water
- the liquid film covering the strip is removed, in particular to allow a correct winding of the strip on the winder.
- the state of the art has spin-drying devices which comprise two substantially parallel pressure cylinders arranged on either side of the strip to be rolled, perpendicular to the direction of travel of the latter and which are applied directly to the band with a determined effort to remove the oil.
- Small diameter pressure rolls are typically used, which wring more effectively, but are more sensitive to sagging than larger diameter rolls.
- the state of the art knows, for example, EP 0 568 418 A1 and EP 1 712 305 A1 of such spin-drying devices.
- Each pressure cylinder is applied to the strip by means of a plurality of rollers distributed along the length of the roll, and along two axes of rotation substantially parallel to the axis of the pressure roll.
- the rollers are supported by a plurality of bearing blocks, distributed over the length of the cylinder, of the pneumatic cylinders, respectively associated with the bearing blocks, making it possible to independently control the pressures exerted on the various subsets of rollers. carried by the bearing blocks.
- Such wiping devices still comprise means for controlling the fluid supply of the pneumatic cylinders, as a function of the width of the band and of its position between the rolls: such a design of Spinning device advantageously makes it possible to exert the application forces of the pressure cylinders, solely or mainly on the part of the rolls in contact with the belt: the compressed air intake is controlled solely by pneumatic cylinders capable of exerting their force on the width of the band to be wrung, while the cylinders of the bearing blocks to the right of the parts of the cylinders projecting laterally of the band are not fed (or fed under reduced pressure): this avoids the defects as mentioned in EP 0 568 418 A1, namely a rolling of the banks of the metal strip and a bad wringing of the median portion of the metal strip.
- the upper assembly comprising the upper pressure cylinder, the support rollers, their bearing blocks, and the corresponding pneumatic cylinders is carried by an upper cross member, positioned above the scroll plane of the strip to be dewatered
- the lower assembly comprising the lower pressure cylinder, the support rollers, their bearing block and the corresponding pneumatic cylinders is carried by a lower crossbar, positioned below the scroll plane of said strip to wring.
- the upper crossmember can be connected to the lower crossmember by means of hydraulic jacks which, when retracted, make it possible to keep the work rolls in the working position, in a first position of the sleepers (illustrated on the left half of Figure 2 of this anteriority) where the pressure cylinders are close together: the positions of the sleepers are fixed by stops adjusted so that the upper cylinder and the lower cylinder exerts no appreciable pressure on the band when the sleepers are in this first position and the pneumatic cylinders associated with these cylinders are not pressurized.
- the deployment of the hydraulic cylinders also allows to separate the sleepers, in a second relative position (shown in the right half of Figure 2) of the lower and upper cross members which allows the operations of change of spin cylinders and pebbles. support, as described below.
- the pressure roll (respectively upper or lower) and the bearing blocks (including the corresponding support rollers) are supported by the same beam.
- Tabs substantially parallel are rigidly secured to both ends of the beam and ensure the maintenance of the cylinder by its two ends, by means of bearings, respectively provided between the ends of the cylinder and the corresponding tabs.
- the bearing blocks are distributed over the length of the beam each bearing block being connected to the beam via a rod passing through a bore of the beam.
- the assembly comprising the support cylinder, the bearing blocks, their support rollers and the beam forms a self-supporting assembly, usually called "cassette" received as an insert in a longitudinal cavity of the cross section U.
- the cylinder bodies are rigidly secured to the cross member, on the other side of the cross member relative to the housing for the cassette, bores being drilled in the cross members in alignment with the bearing block rods. These bores allow the passage of the rods of the pneumatic cylinders, which when pressurized come engage with the rods bearing blocks to transmit the thrust force (as shown in the left half of Figure 2). In the absence of thrust of the pneumatic cylinders (as shown on the right half of Figure 2) springs between the rod and the beam force the bearing blocks and their rollers towards the beam, the rod of each pneumatic cylinder being maintained away from the bearing end of the bearing block rod.
