Definitions

  • the present invention relates to an improved rolling mill for continuously reducing the area of indeterminate lengths of longitudinally traveling metallic wire products and, more particularly, to the type of rolling mill wherein the pass between the respective rolling means is controlled by relative movement of the housing members that revolubly support the rolling means.
  • the hotter rod will buckle between passes and cause what is known in the industry as cobbles.
  • the mill therefore, must be adjusted to the hottest work piece being rolled, and if the draft on the different passes is regulated to keep this product under slight tension, the same adjustment will produce a pull of considerable force on the colder material. Consequently, this pull is the cause of the longer iinny ends which are characteristic of material rolled on straight continuous mills, and it also produces 4a difference in section between the endsand the middle of the material being rolled causing it to eX- hibit a tendency toward flatness in the middle. This matter is especially important in the case of mills rolling more than one line or strand at a time.
  • the primary object of the invention is to overcome the previously described disadvantages and to allow the achievement of rolled products having more accurate dimensions.
  • Another object of the invention is to provide a rolling mill in which the rolling means are carried exteriorly of the housing thereof.
  • Still another object of the invention is to provide a rolling mill housing comprising a fixed portion and another portion which is movable relative thereto, each of said iixed and movable portions carrying one of the complemental rolling means.
  • a further object of the invention is to provide a poweroperated means for actuating the movable portion of said housing and therethrough the area of the pass between the respective rolling means.
  • a still further object of the invention is to provide a series of rolling mills in longitudinal alignment on a supporting member with each mil being rotated at vau angle of 45 to the mill adjacent thereto whereby the entire circumference of the product being worked is properly rolled.
  • FIG. 1 is an isometric view illustrating the essential elements of the new rolling mill
  • FIG. 2 is a side elevational view of the rolling mill
  • FIG. 3 is a section on line 3 3 of FIG. 2;
  • FIG. 4 is a section on line 4 4 of the xed and pivotal housing only of FIG. 2;
  • FIG. 5 is a section on line 5-5 of FIG. 2;
  • FIG. 6 shows an end elevational view of a pair of rolling mills which have been longitudinally aligned and disposed at 45 angles relative to each other in a supporting base;
  • FIG. 7 is a side elevational view of the trough-shaped supporting base member provided with baille means adapted to control the height of the cooling medium relative to the outlet pass of the respective mills.
  • FIG. 1 isometric view of FIG. 1, being more or less schematic, generally shows all of the essential cooperative elements of the new rolling mill in a correlated manner and the operation of which will be best understood from a more careful study of the remainder of the drawings and a perusal of the description material.
  • FIG. l there is shown at 10 a fixed housing which includes an integral upwardly and outwardly projecting portion 11 that extends out over a housing member 12 that is pivotally supported in the fixed housing by trunnions, either of which may include means adapted to transmit transverse movement to the pivotal housing 12.
  • trunnions either of which may include means adapted to transmit transverse movement to the pivotal housing 12.
  • the fixed and pivotal housings are provided with aligned bores 14 and 15 With spaced ⁇ bushings 16 and 17 being provided in the fixed housing to permit transverse and limited rotary movement of the shaft 18 which is fastened to the pivotal housing by means of the pin 19.
  • a threaded shaft 23 which includes at its inner extremity an integrated spherical element 24 that is confined between juxtaposed bearing means 25 and 26 and at its free end with a suitably formed portion adapted to receive a wrench.
  • An internally threaded nut-like member 27 cooperates with the threaded parameter of the cylindrical bearing means 26 and upon rotation thereof pressure is exerted on the rear face of spherical ball 24 when it is desired to adjust the pivotal housing 12 to the fixed housing.
  • the nut 28 is secured iiush against the exterior wall of the cap element 21.
  • the cup-shaped element 21 may include suitable indicating means toassist in aligning the rolls.
  • Another power means mounted adjacent to the torque means and in the fixed housing is provided with an upwardly extending shaft or jack portion which engages the movable housing and is also used to exert a force opposed to the first power means and is relied upon for quick enlarging of the pass between the rolls to prevent jamming or overloading of the mill.
  • FIG. 2 which is a side elevational view of the rolling mill, there is shown the complementally formed rolling mill rolls, one of which is positioned for movement on a shaft mounted in the movable housing 12, the other being positioned on a shaft which is carried in the fixed housing.
  • a suitable hydraulic or pneumatic power means 30 Secured to the outwardly projecting arm 11 is a suitable hydraulic or pneumatic power means 30, the reciprocable depending leg or jack portion 31 of which is adapted to be brought into contact with a hardened steel plate 32 (FIG. 4) which is secured to the upper surface 18 of the movable housing 12.
  • the housing 12, which pivots about the spaced trunnions includes a shaft 33 to the free end of which is secured a rolling means 34 provided with a channeled perimeter and thereby adapted to cooperate with the adjacent roll 35 carried on the lower shaft 44 to producev a finished product of desired circumference. Since the thrust and roller bearing means for each of the parallel-disposed shafts 33 and 44 which carry the rolling means at the rfree ends thereof are substantially identical, the assembly for only three will be described.
  • shaft 33 is revolubly supported by the roller bearing 36, the support means 37 lfor which is secured at its perimeter to a channeled or recessed area within the movable housing 12.
  • the shaft is provided with allochiral bearing means 39.
  • the lower shaft 44 is provided with any suitable coupling means 4S which is associated with the power drive means 46.
  • a source of power which drives into the shaft 44 through coupling 45 may include a driving reduction gear which is preferably of the fioating type, that is, it is entirely supported by the shaft 44 and is simply wedged into rotation by the offstanding dog 45 which rests against the stop 46.
  • a power means 47 which includes a pressure gauge 4S in any suitable manner relative to the fixed housing or any other source of support, it is possible through the contact of dog 45' with the stop 46 carried by the jack 47 to determine the reaction force, and consequently the torque developed by the reduction gear, which is necessary to the control of the rolling operation.
  • FIG. 1 there is shown another power means 50 through the jack or arm portion 51 of which reciprocating motion is converted to an oscillary motion so as to raise and lower the shaft 52 and therethrough adjust the spacing between the complementa] rolls 34 and 35 to regulate the value or thickness of the rolling pass.
  • This organization will be best understood from an examination of FIG. 3 in which there is shown at 10 a portion of the fixed housing, the base of which has been provided with an upwardly extending terraced bore 53 which is gradually reduced, as shown.
  • an apertured cup-shaped element 54 within which is positioned a recessed stub socket 55, the downwardly extending extremity of which is suitably secured to the shaft 51.
  • the annulus 58 which surrounds the upper portion of the stub socket 55 is associated therewith in any manner such as by splining, keying, etc., and adapted to be rotated about a vertical axis upon power being introduced to the cylinder 50. Accordingly, it will be readily appreciated that power can be transmitted from the stub socket through the annulus into the bearing means 59 and therethrough into the nut 60 so as to rotate the same and move the shaft 52 upwardly or downwardly depending upon the direction of movement ofthe shaft 51.
  • the reciprocable shaft 52 is confined to a vertical reciprocatory path by means of the key 61 which is positioned in the housing 10, as shown.
  • the upper free end of the shaft 52 projects entirely through the reduced area of the bore 53 and is correlated relative thereto by means of the sleeve bushings 62 and 63, respectively.
  • the pivotal housing 12 is provided with a recess 64 complemental to the free end of the shaft 52 and is provided with a hardened steel plate 65 adapted to take the wear therefrom.
  • FIG. 6 there is shown a supporting base member 65 which is provided with a trough.
  • the divergent walls that are indicated at 67 and 68, respectively, are positioned at an angle of approximately 45.
  • bafiie means 69 and 71 which are provided adjacent to their upper extremity with means defining openings of any desirable contour but which will be adequate to confine a bath of'fiuid, as shown, and through which the rolled product may pass during its reduction travel through the respective continuous train of mills.
  • the pivotal housing portion 12 is adjusted laterally for coincidence of the roll passes and then is urged in a downward direction upon pressure being introduced to the power means 30, whereupon its shaft 31 will be brought into engagement with the upper portion of said pivotal housing.
  • the power means shown in FIG. 3 and described in connection therewith is used to adjust the spacing between the complemental rolls by rotating the nut 60 by means of the power source, as described, thus regulating the value or thickness of the rolling pass. Accordingly, although these respective power means are'v not connected together, the controls therefor being entirely separate, they are coordinated in order to lproduce the desired product.
  • the power means 30 it is also possible to construct the power means 30 so that it will be double-acting and have its shaft portion 31 fastened in any suitable manner to the pivotalhousing 12 so that it will not only urge said housing downwardly but also can be adapted to lift it upwardly when desired, thus making it unnecessary if desired .to include in the organization the construction shown in FIG. 3.
  • the power supply for the respective power cylinders may be correlated through a control system so that if an accidental overloading occurs, the fiuid being introduced to power means 30 is immediately cut off and introduced into power means 70 thereby raising the tiltable housing 12 upwardly, thus protecting the rolling mill against overloading and damage.
  • An improved rolling mill for continuously reducing the area of indeterminate lengths of longitudinally traveling metallic wire-like products comprising, a relatively fixed housing including a rst shaft means to support a wire reducing rolling means at one end thereof and exterior of said housing, a pivotal secondary housing supported for movement during working in at least one plane relative to said fixed housing and including second shaft means supporting another wire reducing rolling means for cooperation with said first named rolling means, each of said rolling means being formed with complemental grooved areas to provide a product of predetermined cross section, driving means for at least one of said rolling means, means cooperating with said driven means for driving said other rolling means, and a first power operated means on said fixed housing for controlling the movement of said pivotal secondary housing relative to said fixed housing and therethrough the circumferential area of the pass between the respective rolls.
  • the second power operated means comprises a nut-like member mounted for rotation in at least one of said housings, an elongated shaft means including a threaded portion adapted to cooperate with said nut-like member for translatory movement of the shaft means, said shaft means including a free end portion engageable with the other of said housings to thereby control the area of the pass between the respective rolling means.
  • said trough-shaped supporting base member includes bafiie means, said baflie means confining a source of lubricant to the surface area of the wire product passing therethrough.
