Definitions

  • the tension reel disclosed is designed to facilitate rapid replacement of the expandable mandrel as a unit through a construction of associated parts.
  • the expandable mandrel has a flange at one end and an outboard hearing at the other end. Projecting outward from the flange is a stub shaft constructed to fit within a recess formed in a bearing mounted shaft that also has a flange adapted to be bolted and keyed to the mandrel rflange in a driving relation.
  • a rod extends axially from the mandrel a short distance into the bearing mounted shaft where it is connected to levers associated with a piston cylinder assembly for axially displacing the rod to expand the mandrel.
  • the bearing mounted shaft is carried by a sled that is displaceable to remove the shaft from the mandrel while it is supported by a coil lift or other supporting means.
  • a tension reel is conventionally employed to coil metallic strip delivered from a rolling mill as well as a strip processing line.
  • Such a reel usually takes the form of an expandable mandrel constructed with an elongated arbor that is rotatably supported in a housing by bearings and carries a gear that meshes with a drive.
  • the first is to perform maintenance and service operations on the mandrel.
  • Tension reel constructions known in the art are subject to certain disadvantages which the present invention is designed to overcome. With respect to replacing the expandable mandrel, in tension reel construction known in the art this generally takes the form of disassembling the drive housing to remove the extended shaft of the expandable mandrel along with the drive gear and anti-friction bearing assemblies. This operation not only requires considerable time and effort to disassemble and reassemble the drive housing structure but also necessitates supplying and replacing an increased number of parts over that which is actually necessary to effect replacement of the mandrel per se.
  • the mating tapered surfaces formed on the bearing mounted sleeve and the mandrel shaft become very tight and diflicult to separate, particularly after a period of operation.
  • the extended mandrel shaft with its tapered surfaces and axial bore along with the piston cylinder assembly for expanding the mandrel represent an added expense for each replacement mandrel which is not essential to replacement of the mandrel.
  • FIG. 1 is an elevational view, partly in section, of a tension reel incorporating the features of the present invention.
  • FIG. 2 is an enlarged sectional view of a portion of the tension reel illustrated in FIG. 1.
  • the tension reel for winding metallic strip into a coil C.
  • the tension reel includes an expandable mandrel 11 constructed in a manner, per se well known in the art.
  • a bearing assembly 12 mounted on the outboard end of the mandrel is a bearing assembly 12 constructed in any suitable manner and received within a housing 13 which forms part of a weldment 14 secured to the foundation by bolts.
  • a wedge 15 actuated by a piston cylinder assembly is provided to releasably secure the bearing assembly to the housing 13.
  • the mandrel 11 at its inboard end 16 is constructed in a manner to facilitate rapid replacement of the mandrel with respect to its associated drive and support means.
  • the mandrel 11 at its inboard end 16 comprises a plurality of arcuate segments 17 disposed about the outer surface of a support shaft 18.
  • Each of the segments 17 has an enlarged end received within a ring 19 in a well-known manner.
  • the shaft 18 is constructed with a flange 21 which carries a plurality of bolts 22. Projecting concentrically from the flange 1 is a short shaft or stud 23.
  • the shaft 18 and its stud 23 have an axial bore 24 into which there is located a rod 25 that is axially displaceable for the purpose of expanding the segments 17 of the mandrel.
  • a shaft assembly is provided for supporting and driving the mandrel.
  • This assembly comprises a shaft 27 formed with a flange 28 to which the flange 21 is drivingly secured by keys 29 and the bolts 22 with nuts 22a.
  • the shaft 27 at the flanged end has a recess 31 for receiving the stud 23 of the mandrel 11. It is important to note that the stud 23 and the recess 31 extend into the shaft 27 only a short distance to a point where the stud can be supported by an anti-friction bearing block assembly 33 that, together with a bearing block assembly 34, rotatably mounts the shaft 27.
  • these bearing assemblies form part of a sled 35 which is constructed with horizontal projections 36 that are slidably supported in longitudinally arranged guideways 37 formed in a foundation mounted base 38.
  • the sled is provided with a downwardly extending projection to which is secured the rod end of a piston cylinder assembly 39 employed to traverse the sled, hence, also the shaft 27 supported b the bearing block assemblies 33 and 34.
  • the coil C during removal thereof, is supported by a coil lift 41 having a piston cylinder assembly 42 for elevating a support platen 40.
  • the lift 41 is employed to support the mandrel 11 while the drive shaft 27 is retracted to effect replacement of the mandrel,
  • Actuating means are provided for expanding the mandrel 11 which comprises, as shown in FIGS. 1 and 2, a piston cylinder assembly 43 supported by arms 44 extending from the bearing block assembly 33.
  • a cross-head 45 interconnects the rod end of the piston cylinder assembly with one of the ends of spaced parallel arms 46. These arms are pivotally secured at their opposite ends by links 47 to the extensions of the sled 35. Trunnions, not shown, are used to connect the mid-points of the arms 46 to a bearing block assembly 48 which is slidably displaced along the shaft 27 by actuating the piston cylinder assembly 43.
  • the sliding movement of the bearing block 48 is transmitted to the actuating rod 25 of the mandrel by a bar 49 which passes through an elongated slot formed in the shaft 27 and through a narrow slot 25a in the rod 25.
  • the bar 49 is held captive to the bearing assembly 48 by a ring 50, which is easily removable, to withdraw the bar 49 from the slot 25a in the rod 25.
  • a drive 51 interconnects a motor, not shown, with the shaft 27 through a spindle 52.
  • the spindle has a splined end 53 that telescopes into and out of the drive when the drive shaft 27 is retracted relative to the mandrel.
  • the coil lift 41 is elevated by the piston cylinder assembly 42 until the platen assumes a supporting relation with the mandrel, which position is shown by phantom lines in FIG. 1.
  • the mandrel is then disconnected from the shaft 27 by moving the nuts 22a from the bolts 22 following which the bar 49 is removed from the actuating rods 25.
  • the piston cylinder assembly 39 is actuated to retract the shaft 27 from the mandrel 11 by traversing the sled 23 along the guideways formed in the base 26.
  • the mandrel will then be separated from the drive shaft 27 whereby a replacement mandrel can be substituted on the platen 40 by any suitable means, such as a crane.
  • the replacement mandrel is then connected to the drive shaft by following the preceding operation in reverse.
  • the piston cylinder assembly actuated wedge 15 in addition to securing the outboard bearing 12 to the support 4 weldment 14 during the coiling operation, may also be employed to restrain the mandrel 11 from axial movement during the time the shaft 27 is being disengaged from the mandrel.
  • a tension reel constructed in accordance with the present invention permits replacement of the expandable mandrel without replacement of the bearing block assemblies 33 and 34 or the piston cylinder assembly 43 and its associated mechanisms for expanding the mandrel.
  • a reel for coiling metallic strip material having a mandrel adapted to be quickly removed from and replaced in the reel;
  • a drive shaft having a driving member at one end thereof constructed and arranged for connection to said drivable member
  • a reel according to claim 2 wherein said means for supporting said mandrel at its end opposite said one end comprises a bearing assembly mounted on said mandrel;
  • a reel according to claim 3 further comprising wedge means for releasably securing said bearing assembly to said stationary support during displacement of said sled relative to said base incident to removal of said mandrel.
  • a reel according to claim 2 further comprising:
  • a reel according to claim 1 comprising:
  • a reel according to claim 1 further comprising:
  • first and second bearing assemblies rotatably supporting said drive shaft on said sled
  • said first bearing assembly being disposed adjacent to said driving member
  • said second bearing assembly being remotely spaced from said first bearing assembly.
