Definitions

  • Coilers built in accordance with present day technology have proven to possess certain serious dis-advantages and limitations which were pointed up particularly by recently constructed hot strip mills. These mills were designed to produce extremely large diameter coils of very wide strip which was rolled to a very thin gauge. For example, the diameters of the coils were 80 inches, the width and thickness 74 inches, .050 inch, respectively.
  • the present invention provides a coiler characterized by the fact that its side adjacent the strip pass line is completely open and wherein the wrapper roll assemblies of the coiler are so constructed and arranged to be displaceable away from the mandrel in a manner to permit a coil to be formed on the mandrel, wherein the periphery of a completed coil may be arranged in close proximity to the strip pass line, and wherein the mandrel of the coiler is positioned beneath the pinch rolls that cooperates with the coiler, the net eifect being that the strip throat that extends between the pinch roll and mandrel is considerably reduced in comparison to present day coilers.
  • the invention also contemplates divorcing from the coiler one of the guides that form the throat between the pinch roll and the mandrel, and mounting the corresponding guide that forms the opposite side of the throat on one of the wrapper roll assemblies, so that by retracting the last mentioned guide and the one wrapper roll assembly, the periphery of a completed coil can be arranged immediately adjacent to the strip pass line and ready access is provided for the quick removal of a cobbler that may have formed in the throat.
  • the open top construction of the coil will also permit ready access to the wrapper roll assemblies when the coiler is retracted from under the table that is arranged above it, should retraction of the coiler be contemplated.
  • the invention also contemplates in a design employing pivotally supported wrapper roll assemblies, providing for mounting the trunnion shafts that pivotally support the wrapper roll assemblies of the coiler in such a manner that they fall substantially on or below a horizontal plane tangent to the upper periphery of the mandrel wherein a very rigid coiler frame construction is obtained.
  • One form of the present invention provides a coiler having a mandrel arranged in a spaced-apart relationship with respect to the strip pass line and a pinch roll arranged at one side of the coiler having its bite substantially coincident with the pass line, comprising a frame including two support members for supporting on the opposite sides of the mandrel at least one wrapper roller assembly, the wrapper roller assemblies being supported by said support members substantially or below a horizontal plane tangent to the upper periphery of the mandrel, wherein the coiler frame is open on the side adjacent to the pass line and the wrapper assemblies are so constructed and supported by said support members that when they are retracted to their inoperative positions, they permit a coil to be formed on the mandrel, its periphery when completed coming to close proximity to said strip pass line, and at least a portion of the coiler being positioned in a superimposed position relative to the pinch rolls. Should it be desirable to retract the coiler laterally out from under the table which is sometimes done, the present invention contemplates can
  • the invention provides in one form for securing the table that extends above the coiler to the pinch rolls and for providing a truss which extends across the opening provided in the foundation for the coiler which truss receives and supports the drive of the pinch rolls.
  • FIGURE 1 is an elevational view from the operators side of the downcoiler incorporating the features of the present invention and also including a partial showing of some of the associated equipment;
  • FIGURE 2 is a second elevational view taken from the drive side of the coiler.
  • FIGURE 1 With reference to FIGURE 1 there is illustrated a strip entry table over which a strip is fed in the direction indicated by the arrow to the pinch roll assembly 11 consisting of an upper roll 12 and a lower roll 13.
  • the rolls of the pinch roll assembly are rotatably received in an overhung horizontal frame 14 which is secured to the foundation 15 that forms one side of a pit 16.
  • a downcoiler 22 Within the pit 16 there is arranged a downcoiler 22.
  • the coiler is provided with a frame consisting of a longitudinally extending base member 24 having an upright member 25 at its left hand side as one views FIGURE 1, to which there is rotatably secured a transversely arranged trunnion shaft 26.
  • the construction of the frame allows the top of the coiler to be entirely open, in which connection the upright member 25 of the frame terminates on or below the upper periphery of the mandrel 23.
  • a second transversely arranged trunnion shaft 27 is rotatably secured thereto.
  • the trunnion shaft 26 has a complementary trunnion shaft 28, likewise, the trunnion shaft 27 has a complementary trunnion shaft 29, the former being rotatably carried by the upright member 25 and the latter by the base member 24.
  • an arm 31 To the trunnion shaft 26 there is connected an arm 31, to the trunnion shaft 28 an arm 32 is connected, the opposite ends of these arms being connected to a frame 33 of the wrapper roll assembly 34 which, in addition, consist of a roller 35 and a segmental guide 36.
  • the shafts 26-28, 2729 are arranged on or below a horizontal plane tangent to the upper periphery of the mandrel 23, thus leaving the top of the coiler entirely open.
  • FIG. 1 To the trunnion shaft 27, there is connected a pair of relatively movable interconnecting arms 38, the upper arm being secured to a frame 39 of a second wrapper roll assembly 41.
  • the lower end of the frame 39 is pivotally connected to the trunnion shaft 29.
  • the second wrapper roller assembly 41 is provided with a roller 42 and a segmental guide 43.
  • the upper roller assemblies are moved into and out of their operative positions by individual piston cylinder assemblies 40, FIGURE 1 showing the two positions, while FIGURE 2 shows the inoperative positions of each of the wrapper roller assemblies.
  • a guide 44 which forms a substantial portion of the throat 45 of the coiler 22 that extends between the pinch rolls 12 and 13 and the mandrel 23 when the wrapper roller assembly 41 is in its operative position.
  • the upper end of the guide 44 has an extension guide 46a which breaches the gap between the guide 44 and the lower pinch roll 13.
  • a guide 46 Opposed to the guide 44 and pivotally secured to the table 17 serving as a complementary guide for the throat 45, there is provided a guide 46.
  • This guide is mounted on a shaft 47 and connected to a piston cylinder assembly 48 that pivotally moves the guide from an outline position to a substantially horizontal full line position shown in FIGURE 1 for which reason the upper surface of the guide is cut away at 47 so that it will not interfere with the adjacent roller 50 of the table 17 and make posslble that the periphery of the maximum diameter coil can assume a position in immediate proximity to the bottom of the roller 50, as FIGURE 1 clearly indicates by the solid line form of the maximum diameter coil.
  • the two quadrants which are adjacent to the table 17 are entirely open once the wrapper roll assemblies 34 and 41 are retracted so that a coil can be formed in the open spaces between the pinch roll and mandrel.
  • the construction permits the maximum diameter coil to be brought as closely as possible to the pinch rolls 12 and 13 where the periphery of the maximum coil falls in a vertical plane containing the pinch roll 12. Also, the distance between the axis of the mandrel and the path of travel of the strip is approx mately equal to the sum of the radius of the coil and diameter of the table rollers 50.
  • a trailing roller 51 is also provided, which as shown in FIGURE 1 is rotatably carried by an L shaped arm 52 having its upper end pivotally secured to the upright member 25, and its lower end to a rod of a piston cylinder assembly 53a.
  • the roller 51 is brought into contact with a completed coil to keep its trailing end against the body thereof.
  • FIGURE 2 illustrates, the motor 53 provided for driving the lower pinch roll 13 is supported by a truss 54 that extends across the pit 16 being supported by the foundations 15 and 21 at its opposite ends.
  • FIGURE 2 also shows the unrestricted relationship of the elements of the coiler with respect to the truss 54.
  • a similar truss, while not shown is provided for the motor provided for driving upper pinch roll 12.
  • the present adaptation of the invention contemplates the withdrawal of the entire coiler 22, including the mandrel 23, out from under the table 17, for which purpose the base portion 24 of the frame 20 is mounted on guide ways 54a and 55 and a piston cylinder assembly 56 is connected to the coiler 22.
  • the coiler 22 is permitted to be moved laterally without any interference and at the same time the construction allows the right-hand side of the coiler, as one views FIGURE 1, to be mounted under the pinch roll assembly whereby the mandrel is kept as close as possible to the pinch rolls 12 and 13, and accordingly, reducing the length of the throat 45 between the pinch rolls and mandrel 23.
  • the described coiler overcomes each one of the aforesaid enumerated objections of present day coilers and accomplishes each of the advantages that have been previously pointed out.
  • the present invention permits the mandrel to be so located that the distance between the mandrel and the pinch roll substantially equals or is less than that of the diameter of the maximum size coil formed on the mandrel 23, thereby reducing the length of the throat 45 to practically the very minimum distance.
  • the herein disclosed frame construction of the coiler will provide a very rigid construction assuring proper cooperation between the wrapper roller assemblies 34 and 41 and the mandrel 23.
