Definitions

  • the invention relates to a reel according to the preamble of claim 1, as known from document FR-A-2610910.
  • a band reel with an expandable reel mandrel is usually provided for reeling or uncoiling strip-shaped material, for example hot-rolled or cold-rolled steel strip.
  • reels are subject to all types of unfavorable operating conditions, such as high speeds, cantilever loads, heat, water and centrifugal force, all of which greatly degrade the performance or performance of the reel and are a cause for high maintenance costs.
  • a typical reel for winding hot strip in hot strip rolling mills is therefore subject to extremely high dynamic and thermal loads, since hot strips with strip thicknesses of, for example, 25 mm or a strip width of, for example, 2100 mm form a bundle with a weight of up to 45 t have to be wound at 200,000 strip infeeds per year. The strength of the various construction elements of the reel and its serviceability must therefore be carefully considered.
  • the tape reel known from document DE-C-3241870 has, for straight-edged winding and unwinding of metal strips to and from a bundle, devices for displacing the bundle transversely to the direction of the strip during winding and unwinding, which are designed so that a tracking of the Confined to the running belt edge is done by the winding shaft is axially displaceably mounted in a machine stand and is led out of the machine stand on the side opposite the winding mandrel and a slip-on gear is attached there, which is connected to the drive motor via a motion-compensating cardan shaft.
  • the particular problems to be observed when winding hot strip are not addressed in the strip reel known from DE-A-32 41 870.
  • Reel mandrels for hot strip reels are usually driven with spreaders according to the current state of the art.
  • Post-spreading means that the reel mandrel is closed at the strip inlet and is only expanded to about 90% of the spreading amount after one to three turns. This driving style ensures that the first turns are gripped securely and the strip tension is built up quickly.
  • the spreading movement is actuated with the help of a rotating hydraulic cylinder, and the command to actuate the hydraulic valve is given automatically with the aid of a path detection of the band tip.
  • a tape reel of the type described in the opening paragraph is known.
  • the reel shaft is supported in two pedestals, whereby the reel mandrel is additionally supported in a pedestal.
  • the reel mandrel has segment bodies which can be moved in the radial direction and bear against wedge-shaped surfaces of an axially displaceable spreader rod.
  • the spreader rod is passed through the reel shaft and is connected to a coupling which connects the spreader rod to a drive unit acting axially thereon.
  • the object of the present invention is to be able to remove the hot strip which is to be wound onto the coiler mandrel into a bundle safely and without damage from the coiler mandrel as a finished bundle if the spreading movement of the coiler mandrel disadvantageously with the previously described ones for electrical, mechanical or other reasons Consequences could not be carried out. This object is achieved with claims 1 to 10.
  • the coupling with a play corresponding to the expansion of the reel mandrel is arranged between an emergency expansion device and the housing of the hydraulic drive, the emergency expansion device and the housing of the hydraulic drive being immovable in relation to the mandrel body in the axial direction and wherein the movement of the coupling in the sense of a diameter reduction of the reel mandrel is limited by the emergency expansion device and the emergency expansion device enables an additional release of the axial mobility of the expansion rod connected to the coupling by a certain amount.
  • the device for emergency despreading surrounds the spreader bar in an annular manner and that the coupling is provided with a stroke limiting ring.
  • the emergency expansion device is arranged in an easily accessible area of the reel system and can therefore be actuated easily and quickly in the event of faults.
  • the emergency expansion device expediently consists of an annular centering sleeve pushed onto the expanding rod with an integrally formed flange which can be connected to the mandrel body, and of at least two spaced-apart cam disks which are rotatably held on the centering sleeve and at least one holding piece which is detachably connected to the cam disks in the sense of unlocking.
  • the holding piece is both secured against rotation by means of support elements engaging on the mandrel body and also fixed without play in the axial direction.
  • the holding piece is shaped as an angle iron, the long leg of which engages over the radial outer surface of the cam disks and is arranged in grooves recessed on the radial outer surface of each cam disk and the angled short leg of which engages in an annular groove in the flange of the centering sleeve.
  • the holding piece has a predetermined separation point in the area between the cams for the purpose of unlocking.
  • the emergency expansion device should be unlocked by removing the retaining piece connecting the cams by loosening a screw connection.
  • the holding piece is separated at the target separation point, for example by flame cutting.
  • the emergency despreading device is thus unlocked and the axial movability of the spreader bar in the sense of claim 1 for despreading the coiler mandrel is established.
  • the cam disks each have two opposing cam segments, the segment surfaces of which are designed as inclined support planes, which are advantageously connected to one another in a permanent positive fit, expediently such that the common center of gravity of the cam segments is in the middle of the coiler mandrel or lies in the axis of the spreader bar.
  • the line of action of the axial force falls superimposed curve pieces together with the center of the coiler mandrel, which means that there is no moment on the spreading devices in the coiler mandrel.
  • cam disks have on their outer circumference an actuating member causing the disk rotation, preferably an actuating pin with which the cam disks on the annular centering sleeve can be rotated manually from the outside by means of a special tool. It is expedient that the cams are rotated in the opposite direction on the centering sleeve by such angular degrees that their inclined support planes, viewed in the axial direction of the spreader bar, stand on each other to reduce the distance with non-positive engagement.
  • the support planes of the cam segments are permanently on top of one another even during the distance-reducing rotation of the cam disks, so that tilting moments on the expanding rod are avoided and consequently tilting of the expanding elements in the coiler mandrel is prevented. As a result, this leads to a very safe de-spreading of the reel mandrel in the previously discussed accidents.
  • Fig. 1 the reel mandrel 1 of a strip reel for winding hot strip 2 from a hot strip rolling mill, not shown, is shown.
  • 1.1 shows the hydraulic drive 3 —a double-acting piston-cylinder unit — for the spreader rod 5 arranged inside the mandrel body 4.
  • the piston rod 6 of the drive 3 is connected to the spreader rod 5 by means of the split coupling 7.
  • 1.2 shows the mandrel body 4, the bearing 8 and the gear pair 9 for the rotating drive in an extension of FIG. 1.1.
  • 1.3 shows, as an extension of FIG. 1.2, the bearing 10, the mandrel body 4 and the spreader rod 5 which is axially movable in the mandrel body 4.
  • the spreader rod 5 is connected to the segments 13 by means of tabs 11 which are passed through openings 12 in the mandrel body connected to the coiler mandrel on which the hot strip 2 is wound.
  • the spreader rod 5 has a plurality of wedge-shaped planes 14, on which wedge elements 15 are supported, which are guided through openings in the mandrel body 4 and act on the segments 13 in the radial direction. If the pressure chamber 16 of the hydraulic drive 3 is acted upon by a hydraulic medium, the spreader rod is moved in the direction of movement (arrow 17).
  • the wedge elements 15 migrate upward on the wedge surface 14 and press the segments of the reel mandrel radially outward in the sense of an increase in diameter.
  • the expansion rod 5 moves as expected in the other direction of movement and the wedge elements 15 on the wedge surfaces 14 radially inwards.
  • the segments 13 - pulled through the tabs 11 - move radially inwards, so that the diameter of the reel mandrel is reduced.
  • Fig. 1.1 to Fig. 1.3 the position of spreader rod 5, wedge elements 15 and segments 13 is shown in the upper half of the figure, which corresponds to a re-spreading to approximately 90% of the maximum possible spreading amount.
  • the lower half of the figure shows the position of the spreader bar, wedge elements and segments in which the hot strip 2 is threaded onto the coiler mandrel 1.
  • the exact threading position ie the inlet diameter, is predetermined by the stroke limiting ring 19.
  • the stroke limiting ring 19 lies flush between the coupling 7 and the emergency expansion device 20. From what has been said above about the mode of operation of the reel mandrel, it can be seen that the stroke limiting ring prevents the further axial movement of the spreader rod 5, even if the pressure chamber 18 of the hydraulic drive 3 additionally with the hydraulic one Medium should be pressurized. A further axial movement of the spreader rod 5 in the sense of a reduction in diameter for the reel mandrel can only be undertaken if the emergency despreading device 20 additionally releases the axial movability of the spreader rod by certain travel amounts.
  • the emergency spreading device 20 is shown.
  • the machine parts described in Fig. 1 are identified by the same reference number, so the hydraulic drive 3 with pressure chamber 16, 18, piston rod 6, clutch 7, stroke limiting ring 19, spreader rod 5 and mandrel body 4.
  • the emergency expansion device consists of an annular push-fit on the spreader rod 5 Centering sleeve 21 with molded, with the mandrel body 4, for example Screw-connectable flange 22.
  • On the centering sleeve 21 two mutually spaced, rotatably held and distance-changing cams 23, 24 are arranged.
  • the cams 23, 24 are connected to each other with the aid of a holding piece 25 and releasably by means of the screw connection 26, 26 '.
  • the emergency expansion device 20 and the coupling 7 are coaxially surrounded by a pipe section 27, the pipe flanges 28, 29 of which are connected on the one hand to the hydraulic drive 3 and on the other hand to a pipe sleeve 30 seated on the mandrel body 4.
  • the pipe section 27 is cut out in the area of the coupling and the emergency expansion device 20 on the outer circumference.
  • Actuating bolts 32, 33 are guided through the pipe cutout 31.
  • Two actuating bolts are provided for a cam plate 23 and 24, respectively. With the help of the actuating bolts, the cams are rotatably held on the centering sleeve 21.
  • the cam plate 23 has a projection 34 and leaves an axial movement gap 35 open between the centering sleeve 21 and the projection 34.
  • the holding piece 25 has support elements 36, 37.
  • the support element 36, 37 is designed as a support arm which is supported on both sides of the pipe section 27 in order to prevent inadvertent rotation of the emergency expansion device 20 on the expansion rod 5.
  • Another support element is a connecting tab 38, which is seated on the holding piece 25 and is fastened to the tubular piece 27 with a screw connection (FIG. 2). As shown in FIGS.
  • the holding piece 25 is shaped as an angle iron, the long leg of which overlaps the end faces of the cams 23, 24 and is arranged in grooves 39 recessed on the radial outside of each cam and the angled short leg of one Ring groove 40 engages in the flange 22 of the centering sleeve 21.
  • the adjustment of the holding piece 25 in the annular groove 40 in connection with the screw connection from connecting bracket 38 to pipe section 27 prevents an axial change in position of the emergency expansion device 20 on the expansion rod 5.
  • FIG. 4 and FIG. 5 show that each cam plate 23, 24 has two mutually opposite cam segments 41, 42, the segment surfaces 43, 44 of which are designed as inclined support planes 45, 46.
  • the slope X of the support planes 45, 46 is selected to be at least as large as the axial travel of the spreader rod 5 required for an emergency despreading of the coiler mandrel 1.
  • the size of the segment surfaces is selected so that its permissible surface pressure is not exceeded.
  • the curve segments overlap in an angular range of a maximum of 90 °.
  • the curve segments are designed so that their common area center lies in the middle of the coiler mandrel or in the middle of the spreader bar.
  • the lower half of the figure shows the so-called threading position of the hot strip 2 on the coiler mandrel 1 or the threading position of the spreader rod 5.
  • the emergency despreading device 20 as follows: The screw connections 26, 26 'between the holding piece 25 and the cams 23, 24 are loosened and the screws removed. The cams can now be rotated on the centering sleeve 21.
  • the cam disks are rotated by the actuating bolts 32, 33 in the opposite sense by such angular degrees that the inclined support planes 45, 46 of the cam segments 41, 42 slide on one another in the manner of a screw on a coiled surface.
  • the distance between the cams is included
  • the hydraulic drive 3 can move the spreader rod 5 in the direction of despreading — that is, counter to the direction of the arrow 17 — until the stroke limiting ring is brought into contact again with the outer cam plate 23.
  • the diameter of the reel mandrel is inevitably reduced by a certain amount that is large enough to be able to strip off the bundle that is jammed due to the failure of the re-expansion using the usual measures.
  • the holding pieces 25 are separated in the area between the cam disks 23, 24 at a marked predetermined separation point 47, for example by flame cutting, after which the two cam disks can be rotated in the opposite direction as previously described, with which an axial stroke of the expansion rod 5 is free and thus the reel mandrel can be closed. Since the curve pieces are non-positively locked after removal of the holding pieces 25 (by unscrewing or by separating cuts), the curve pieces will not twist automatically as a result of the friction between the segment surfaces, so that the action of an external impact force on the actuating bolts will be necessary to loosen them.
  • the emergency spreading device 20 can be adapted to a wide variety of operating conditions by different design of the stroke limiting ring 19 and the incline of the inclined support planes 45, 46 of the cams 23, 24.
