Definitions

  • FIGURE 1 is a fragmentary, broken perspective view of apparatus embodying the invention
  • FIGURE 2 is a view, partially in section, generally corresponding to the line 2-2 of FIGURE 1, and
  • FIGURE 3 drawn to a smaller scale
  • FIGURES 4, and 6 are sectional views generally corresponding to respective lines 33, 4-4, 5-5 and 66 of FIGURE 2.
  • FIGURE 1 there is rather diagrammatically illustrated a machine base 10 having a transversely projecting portion 11 which overhangs a pass line X along which tubing T and the like moves longitudinally.
  • a plurality of roll passes 12 Supported beneath the base portion 11 are a plurality of roll passes 12 through which a piece of tubing T progressively travels.
  • Each roll pass may be formed of a pair of rolls 13, 13.1 mounted in side-by-side relation for rotation on shafts 15, 15.1, respectively, the rotational axes of alternate passes preferably being disposed normal to each other.
  • the roll passes 12 are preferably identical, with the possible exception that the rolls of each pass may differ slightly from each other, a detailed description of but one roll pass will be sufficient.
  • FIGURE 2 it will be noted that while all of the parts associated with shaft 15 have been shown in section, most of the corresponding parts associated with shaft 15.1 and carrying the same reference number but with the suflix .1, are shown in elevation in the interest of simplicity and clarity. Such corresponding parts, however, are identical and thus a detailed description of only the parts associated with shaft 15 is necessary.
  • Shaft 15 is rotatably mounted within a sleeve 16 by axially spaced, anti-friction bearings 17, 18 of conven- Patented Oct. 24, 1967 tional roller or ball type.
  • a tubular spacer 19 maintains the hearings in the proper spaced relationship.
  • the lower, projecting portion of shaft 15 has a tapered portion 20 on which the previously mentioned working roll 13 is mounted by means of a tapered sleeve 120.
  • a nut 21 is threaded on the shaft 15 and removably holds the roll 13 thereon.
  • Sleeve 16 is rigidly supported in the housing part 11 for both rotation and axial movement by means later to be disclosed and, with reference also to FIGURE 3, the bore of sleeve 16 in which shaft 15 is mounted is eccentric to the outside diameter of the sleeve so that rotation of the hereinafter to be referred to ec-cenric sleeve 16 effects transverse movement of the shaft 15.
  • Rotatably mounted on the upper (in the position of parts shown) end of the eccentric sleeve 16 is an externally threaded sleeve 22 having an inwardly directed annular flange 23.
  • An anti-friction thrust bearing 24 is inter-posed between the sleeve flange 23 and a shoulder on eccentric sleeve 16 while a similar thrust bearing 25 is disposed on the other side of the sleeve flange 23.
  • a cap member 26 is bolted to the end of the eccentric sleeve 16 and clamps to the latter, the externally threaded sleeve 22 and the thrust bearings 24, 25.
  • a suitable anti-friction bearing 27 may be interposed between the cap member 26 and the adjoining portion of the shaft 15.
  • the upper portion of externally threaded sleeve 22 is provided with external, longitudinally extending rectilinear splines 28.
  • a worm gear 31 which encircles the eccentric sleeve 16 and maintains such gear against a shoulder 32.
  • gear 31 is engaged with longitudinally extending, rectilinear splines 33 formed on the exterior of the eccentric sleeve 16.
  • externally threaded sleeve 22 is threaded in the nut member 29 and, threaded on the threaded sleeve 22, is a worm gear 34.
  • gear 34 abuts the nut member 29 and functions like a jam nut to lock the externally threaded sleeve 22 to the nut members.
  • a worm gear 35 Disposed above the gear 34 and engaged with the splines 28 of the externally threaded sleeve 22 is a worm gear 35 confined against axial movement by flanges 36 formed in a housing member 37 which is bolted to the base part 11 and through which both shafts 15, 15.1 project.
  • an adjusting shaft 38 extends transversely of the shafts 15, 15.1 and has worms 39, 39.1 keyed or otherwise afiixed thereto.
  • Worm 39 is engaged with worm gear 31 while worm 39.1 is engaged with worm gear 31.1, the arrangement being such that when shaft 38 is rotated by a suitable handwheel or the like (not shown), the worm gears 31, 31.1 together with their eccentric sleeves 16, 16.1 will be rotated simultaneously.
  • the gears and their Worms are so chosen that rotation of shaft 38 in one direction effects rotation of worm gear 31 in a clockwise direction and worm gear 31.1 in a counter-clockwise direction.
  • rotation of shaft 38 in the opposite direction reverses the direction of rotation of worm gears 31, 31.1.
  • housing 37 rotatably supports shafts 40, 40.1 on opposite sides of the shafts 15, 15.1.
  • Shaft 40 has a worm 41 keyed or otherwise secured thereto and engaged with the worm gear 35 while the shaft 40.1 has a worm 41.1 engaged with the worm gear 35.1.
  • the arrangement is such that rotation of shaft 40 will effect rotation of worm gear 35 and consequent 3 rotation of the externally threaded sleeve 22.
  • rotation of the shaft 40.1 will effect rotation of the worm gear 35.1 and its externally threaded sleeve 22.1.
  • the housing 37 rotatably supports a shaft 42 directly beneath shaft 40 and a shaft.42.1 directly beneath the shaft 40.1.
  • Shaft 42 will carry a worm engaged with the worm gear 34 while shaft 42.1 will carry a. worm engaged with ,the worm gear 34.1.
  • rotation of the shafts 42, 42.1 will respectively effect rotation of' the worm gears 34, 34.1.
  • all of the shafts 38, 40, 40.1, 42 and 42.1 may be provided with suitable handwheels or the like to facilitate rotation thereof.
  • Means are provided for retaining the eccentric sleeves against movement and, as best seen in FIGURE 5, such means comprises a pair of opposed blocks 43, 44 on a rotatably supported rod 45.
  • the blocks 43, 44 have arcuate surfaces complementary with the exterior of the eccentric sleeve members, such blocks functioning as wedges as will appear.
  • Block 43 is seated against a shoulder 46 on the rod 45, the rod being freely rotatable within such block.
  • block 44 is internally threaded to cooperate with a threaded portion 47 of the rod 45 and a compression spring 48 encircles the rod between the two blocks and exerts a force yieldably urging the blocks away from each other.
  • Floating axially on a splined portion 49 of the rod 45 is a miter gear 50 which meshes with a miter gear 51 carried by a shaft 52 rotatably mounted in the base portion 11.
  • eccentric sleeves 16, 16.1 are so disposed that shafts 15, 15.1 are in their most closely spaced position and are, at the same time, both in their most elevated positions.
  • rod 45 When it is desired to shift the shafts 15, 15.1 transversely, rod 45 will be rotated by means of shaft 52 (see FIGURE 5) in a direction to permit spring 48 to separate the blocks 43, 44 and shift them out of wedging engagement with the eccentric sleeves 16, 16.1. With the blocks thus disengaged from the sleeves, shaft 38 (FIG- URES 2 and 4) may be rotated to simultaneously rotate the worm gears 31, 31.1 and thus rotate respective eccentric sleeves 16, 16.1. When the shafts 15, 15.1 are transversely positioned as required, shaft 52 will again be rotated to draw the blocks 43, 44 toward each other to wedging engagement with the eccentric sleeves 16, 16.1 to thus lock the latter against movement from their selected positions.
  • worm gear 34 Upon the desired axial positionment of the shaft 15, worm gear 34 will once again be rotated to abut the nut member 29 thus locking the threaded sleeve 22, the eccentric sleeve 16 and the shaft 15 against axial movement. Also, the blocks 43, 44 will again be wedged against the eccentric sleeves 16, 16.1 to further hold them in position by rotation of the shaft 52 as previously described.

  • An improved mill for working longitudinally moving elongated stock comprising a pair of rolls which together form a pass through which the stock is fed, an eccentric member supporting each roll for rotation about an axis spaced laterally of the axis of its supporting member, means connecting said eccentric members together for simultaneous and equal rotation in opposite directions to thereby effect movement of said roll axes toward and away from each other to maintain a fixed position for the pass line while providing adjustment of the pass size, means for moving said connecting means to provide for adjustment of the pass size, and locking means separate from said moving means for locking each of the eccentric members independently against movement once the pass has been adjusted to a desired size.
