Definitions

  • the invention relates to a reel, in particular for sheet metal strips, with an expanding mandrel which has annular, elastic expanding bodies which sit in an axial row next to one another on a mandrel core connected to the reel shaft and change their outer diameter by means of a pressure-controlled cross-sectional deformation.
  • the edge beads go back and the expansion rings assume their basic shape with a smaller diameter than the bead diameter.
  • the pressure rings By appropriate loading and unloading of the pressure rings it is indeed possible to increase or decrease the mandrel diameter dependent on the expansion rings and thus to spread or shrink the mandrel, but this does result with these expansion rings only a relatively small expansion area, since otherwise the elastic material of the expansion rings would be destroyed.
  • the actuation of the pressure rings be it hydraulic or mechanical, is quite complex, which is also associated with the risk of leakage in a hydraulic system and thus inadmissible contamination of the metal strip.
  • a major disadvantage of this known expanding mandrel is, however, that the winding surface is composed of the individual edge beads of the expanding rings which are spaced apart from each other to a certain extent, which can easily result in undesirable impressions, at least in the first turns, particularly in the case of thin sheet metal strips.
  • the expanding mandrel is formed from a slotted, resilient mandrel jacket, in which the expanding bodies engage on the slot edges and press them apart to expand the expanding mandrel.
  • the edges of this gap press into the sheet metal at the first layers of the sheet metal strip to be wound up must be regarded as a considerably serious disadvantage, which should be avoided at all costs.
  • the mandrel jacket cannot be supported along its circumference because the expanding bodies, which interact in the manner of a wedge gear, are not pressed apart radially but tangentially.
  • the invention is therefore based on the object to avoid these disadvantages and to improve a reel of the type described in such a way that its mandrel, despite its simple construction, has a large spreading area, that its winding surface cannot leave any impressions even with the thinnest strips, and that its operation and Maintenance does not pose any problems.
  • the invention solves this problem in that the expansion bodies are resiliently surrounded by a slotted mandrel jacket, preferably made of spring steel, the circumferential length of which corresponds to the circumference of the expanded mandrel, the expansion bodies being hollow and the pressure medium directly acting on the inner wall thereof.
  • a completely smooth winding surface is obtained through the mandrel jacket, so that there is no danger of being pressed in even for the thinnest metal strips. Since this jacket is slotted, it can easily follow any spreading and shrinking movement of the mandrel, the slot edges of the jacket abutting one another when the mandrel is spread and overlapping when the mandrel is shrunk. To make it easier to slide the edges over one another, they can be bevelled accordingly.
  • the mandrel jacket automatically follows the expanding or decreasing expansion bodies, and a properly functioning expanding mandrel results with a consistently smooth surface.
  • the hollow expansion bodies can be greatly enlarged in a simple and safe manner by appropriate pressure medium filling, which makes a large expansion area possible without having to accept the risk of damage or contamination. Since there is no special effort required to directly act on the interior of the expansion body, and the achievable expansion force significantly exceeds the other radial forces that occur, such as coil weight and band tension, so that the large surface pressure between the pressurized expansion bodies and the mandrel jacket is sufficient to transmit the required torque by far overall a very simple, failure-resistant construction.
  • the expansion bodies consist of pneumatic tires mounted on rim-like rings of the mandrel core.
  • These pneumatic tires can be constructed similarly to car tires with radial fabric and, by simply inflating them, bring with them a large difference in diameter between the unpressurized and inflated state, only a compressed air line being required to apply the pneumatic tires.
  • the supply of the line through the rim-like rings is particularly simple.
  • the pneumatic tires can have a flat elliptical cross-section that can be inflated into a circular shape, or the inflated pneumatic tires can have a substantially square cross-section, the radial sides of which can be folded or dented when the pressure is reduced.
  • the pressure medium line leading to the expansion bodies can be connected to one Vacuum space can be connected.
  • the pressure in the expansion bodies can be quickly reduced from the outset with air as the pressure medium, the expansion mandrel can be shrunk even faster by connecting the compressed air line to a vacuum.
  • the stop according to the invention consists of a guide bar articulated at a distance from the slot edge on one circumferential end of the sheath, or the like with a radially displaceably mounted bolt on the other circumferential end of the sheath. cooperates.
  • the two edges of the mandrel casing can be shifted against each other until the bolt rests on one end of the guide rail in the spread position and on the other end of the guide rail in the shrink position.
  • mandrel jacket or the like radially inwardly directed segments. as an axial securing device, to which corresponding support surfaces on the mandrel core are assigned, thus preventing an undesired axial pulling off of the mandrel jacket.
  • the expanding mandrel 1 of a reel which is not otherwise shown in detail, consists of a hollow mandrel core 2 forming part of the reel shaft, on which pneumatic tires 3 are mounted axially next to one another and fastened to rim-like rings 4.
  • Each pneumatic tire 3 is connected via a radial feed line 5 to a Drudkluft line 6 laid in the hollow mandrel core 2.
  • a slotted mandrel jacket 7 made of spring steel resiliently surrounds the pneumatic tires 3, 3 support disks 8 being provided on the mandrel core 2 for supporting the mandrel jacket 7 in the case of pressureless tires.
  • the pneumatic tires 3 have a flat elliptical cross-section which does not protrude beyond the supporting disks 8, so that the shrinking position of the expanding mandrel 1 is given by these supporting disks (FIGS. 1 and 2).
  • the pneumatic tires 3 are now via the compressed air line 6 and the supply line gen 5 with compressed air, whereby they are inflated to a circular cross section. Since their outer diameter increases considerably, they lie against the mandrel jacket 7 and press it off the support disks 8 into the spread position, in which the slot edges 9, 10 of the mandrel jacket 7 abut one another and the mandrel jacket has a continuously smooth, circular-cylindrical winding surface forms (Fig.
  • each stop 11 consists of a slotted guide rail 12 which is pivotally articulated at a distance from the edge 9 of the jacket on the end of a nose 13 of one jacket end, a bolt 15 engaging in the slot 14 of the rail 12 which engages in a holder 16 at the other jacket end is mounted radially displaceable.
  • This bolt 15 can slide back and forth in the rail slot 14 and thus allows the casing edges 9, 10 to be pushed against one another when spreading or shrinking, the end stop of the bolt in the slot 14 determining the maximum spreading width in which the edges 9, 10 lie flush against one another .
  • the compressed air line 6 can be connected to a low-pressure space, not shown.
  • segments 18 projecting inward are secured as axial securing means, to which corresponding support surfaces 19 on the mandrel core 2 are assigned. Support surfaces 19 and segments 18 can slide radially against one another and thus permit the spreading movement of the mandrel, but prevent axial movement of the mandrel casing 7 relative to the mandrel core 2.
  • tires of other cross-sectional shapes which bring about a large difference in diameter between the unpressurized and inflated state can also be used.
  • a pneumatic tire 20 with an approximately square cross-section in the inflated state is possible, the radial sides 21 of which, when the pressure drops, allow the spreading or shrinking movement to result from a kind of concertina effect of the tires.
