Definitions

  • This invention relates to a feed mechanism or directing guide for a rolling mill. It more particularly pertains to a switching means for directing successive lengths of product from a merchant mill alternately into two different paths such as to two gathering tables.
  • the directing guide of this invention is used for the same purpose and is an improvement over the one described in US. Patent Number 3,073,426 (Ser. No. 38,507, filed June 24, 1960 by the present inventors).
  • the directing guide of this patent consists of two independent elongated dual channel guides one of which can be shifted horizontally to receive bar stock from the delivery table alternately in each of its channels or troughs.
  • the two channels of the other guide are shifted vertically to receive lengths of bar stock alternately from each channel of the other member and direct them to the gathering tables. While the directing guide of the patent operates very satisfactorily it does consist of two independent directing members and thus might be considered to be unduly mechanically complex.
  • the horizontal and vertical movements of the guiding channels are consolidated in a single four channel assembly. This results in a simpler, more efllcient mechanical design.
  • FIGURES 1 through 7 are plan views of the directing guide proper showing the guide in its successive different positions during operation;
  • FIGURES 1a through 7a are schematic end views of the guide, as shown in FIGURES 1 through 7, respectively, as viewed from the delivery table, the view being indicated by the direction arrows.
  • FIGURES 1a through 7a show the floors of the channels as being about level in the different positions of the guide for purposes of clarity; but in actual practice they do not quite match, as is shown in FIGURES 8 through 11;
  • FIGURES 8 through 11 are perspective drawings of the guide in its different operating positions, FIGURE 8 corresponding to FIGURE 1, FIGURE 9 corresponding to FIGURE 3, FIGURE 10 corresponding to FIGURE 4, and FIGURE 11 corresponding to FIGURE 6;
  • FIGURE 12 is an end view of the direction guide complete with top covers and FIGURE 13 is a sectional elevation view taken along line 1313 of FIGURE 12.
  • FIGURE 12 indicates by means of dotted lines how the top covers and the upper horizontal surfaces may be swung aside to allow cobbles to be removed.
  • FIG- URE 13 shows the pivoting arrangement used to allow vertical and horizontal movement of the directing guide, and
  • FIGURES 14 and 15 illustrate by top and elevation views respectively the means for vertically and horizontally positioning the end of the directing guide with respect to the delivery table.
  • FIGURES 1 through 7 Only the first of the drawings in the series of FIGURES 1 through 7, FIGURES la through 7a and FIGURES 8 through 11 are completely numbered to prevent undue repetition.
  • the element 5 at the left of the directing guide is a partial view of the end of the delivery table at the entrance of the guide and the passageways 6 and 7 to the right or exit end of the guide are troughs of the two gathering tables with a divider 8 therebetween.
  • the directing guide proper i.e. without top cover and means for pivoting the top cover and the upper horizontal surfaces, consist of left and right elongated members about feet long generally indicated by the numbers 10 and respectively.
  • Members 10 and 30 have upper horizontal surfaces 11 and 31 respectively extending the length thereof, lower horizontal surfaces 12 and 32 respectively, upper outer side walls or outboard vertical surfaces 13 and 33 respectively attached to the upper horizontal surfaces and extending the length thereof which act as retaining side guides, and lower outboard vertical surfaces 14 and 34 respectively that taper from full trough width at the entrance of the directing guide to zero trough width at a point about 13 feet back.
  • each elongated member has an upper inboard vertical surface or dividing side guides 15 and 35 respectively attached to the upper horizontal surfaces 11 and 31. These are about 7 feet long and run from the end adjacent the gathering tables to a point less than midway of the length of the guides and short of the point where surfaces 14 and 34 come to zero trough width.
  • each elongated member in cross section form two L-shaped (or reverse L-shaped in the case of the right member), passageways one above the other with the under side of the upper horizontal surface acting as an enclosing top surface for the lower passageway.
  • the members 10 and 30 are adjacent to each other so that the respective passageways can be brought into register to permit mill product to transfer from the lower horizontal surface of one to the upper horizontal surface of the other.
  • the two elongated members are pivotedly mounted at the ends adjacent to the gathering tables for both horizontal and vertical movement of the end adjacent to the delivery table.
  • the delivery guide as a whole is mounted in a rigid fabricated steel frame only a portion of which is shown.
  • Frame 40 is supported on four heavy duty wheels 41, 42, 43 and 44.
  • the wheels roll on suitable rail sections 45, 46 and 47 and permit the frame to oscillate in a horizontal plane, as indicated by the dotted lines in FIGURE 14, to alternately align the front ends of the elongated members 10 and .30 with the delivery table 5.
  • a vertical kingpin 48 on a rigid mount 49 is located on the center line between the two elongated members and engages a socket in the rear of frame 40. This forms the pivot point of the horizontal motion.
  • the rear ends of the elongated members are mounted on a common horizontal shaft '50 which permits them to be pivoted in vertical planes.
  • the other ends of the elongated members Itl and 30 are supported by a horizontal walking beam type of dual crank.
  • This dual crank comprises a driving means 51 with driveshaft 52, and a crank arm 53 connected thereto and to a connecting rod 54.
  • Connecting rod 54 attaches to a crank arm 55 on the walking beam 56 and when it reciproeates back and forth it causes the Walking beam to oscillate about pivot 61 which is rigidly mounted by means not shown.
  • One end of the walking beam 56 is attached by vertical strut 57 to a rigid car 58 on an elongated member 30 and the other end connects with a similar ear 59 by means of a vertical strut 60 to member 10.
  • Linkages 57 and 6%) are slightly offset on a horizontal shaft, not shown. This arrangement simultaneously causes one elongated member 3 to raise and the other to lower with harmonically balanced motions when driving means 51 is operating.
  • FIGURES l2 and 13 illustrate the top moveable covers and the means for swinging aside both the top covers and the top horizontal surfaces 11 and 31.
  • the ends of the horizontal surfaces 11, 31, 12 and 32 are downwardly inclined somewhat as shown in FIGURES 8 and 11 and account for their appearance in this drawing. This inclination is to facilitate entry and passage of the mill product.
  • the top covers of the elongated members and 3t comprise horizontal members 80 and 31 which do not extend the full length of the passageway. Attached to the inner edges thereof are vertical enclosing walls 95 and 96. Covers 3i) and 81 are rigidly mounted on supporting struts 82 and 83 on member 10 and 84 and 85 on member 30.
  • the upper side walls 13 and 33 are integral with the upper horizontal surfaces 11 and 31, forming an L-shaped unit.
  • Each integral L-shaped unit is attached to vertical arms '88 and 89 and 90 and 91 which are also pivotedly mounted on horizontal pins 86 and 87.
  • either of the top covers can be independently swung aside to permit access to horizontal surfaces 11 and 31, or the covers along with the horizontal surfaces 11 and 31 can be opened to permit access to horizontal surfaces 12 and 32. It can be seen from FIGURE 13 that the portions of the upper L-shaped channels that can be moved in this manner do not extend the full length of the directing guide but terminate at a point 92 in front of the inboard sidewalls and 35.
  • the operation of the directing guide is as follows: When it is intended that a first length A of mill product go into trough 6 of the left gathering table, elongated member 30 is positioned horizontally to line up with the delivery table 5 and is elevated so that the lower horizontal surface 32 is about on level with the surface of the delivery table. The front end of length A enters the lower passageway of member 30 in this position. Membeiid at this point is in a lowered position so that its upper horizontal surface 11 is able to receive the mill product from the lower passageway of member 30. This position is shown in FIGURES 1 and la.
  • the lower passageway of member 10 is thus in position to receive the next closely following length B of mill product as shown in FIGURES 4 and 4a and direct it to the upper horizontal surface 31 of member 30 and thus into trough 7 of the gathering tables. Thereafter the horizontal position is again shifted to align member 30 with the delivery table as shown in FIGURES 5 and 5a and member 3d is then elevated and member 19 depressed as shown in FIGURES 6 and 6a which thus puts the 4 lower passageway of member 30 in position to receive the next length C of mill product as shown in FIGURES 7 and 7a. This completes the cycle.
  • Driving means 51 and 71 are, of course, properly synchronized to operate in harmony.
  • the movement of the directing guide can be activated with respect to the time the shear makes a parting cut or the ends of the lengths of mill product can be observed in some manner such as photoelectrically to activate the directing guide.
  • the relative level of the guide with respect to the delivery table can be changed as desired by any suitable means to facilitate passage of different sizes of mill product e.g. round, then 4" x 4 angle.
  • the whole of the directing guide may also be slightly inclined towards the gathering tables.
  • the device of the present invention makes it possible to direct closely spaced successive lengths of mill product alternately to troughs 6 and 7 without interruption, no matter how closely the front end of a following bar is to the rear end of a preceding bar.
  • This apparatus operates smoothly and directs the mill product positively to the proper path without damage thereto.
  • the directing guide is not dependent upon very accurate timing and functions during the relatively long interval of time when the mill product is passing through it and not during the very short interval time between the adjacent ends of successive lengths. Its construction is simple and maintenance problems are reduced to a minimum.
  • this invention is an improved switching mechanism for directing successive lengths of mill product from a delivery table of a rolling mill alternately to two cooling beds.
  • the switching mechanism consists of right and left contiguous elongated guides, each of which has an upper and a lower passageway with the floors of the lower passageways tapering from full floor with at the entrance to zero floor width at a distance about /3 to /3 the length of the guides.
  • the lower passageway of one guide communicates and is level with the upper passageway of the other at a point in advance of the point of zero floor width so that the mill product can transfer from the lower passageway of the one guide to the upper passageway of the other.
  • the guides are pivoted at their exit ends for vertical and horizontal movement of the entrances of the guides.
  • a positioning mechanism alternately horizontally and vertically positions first one guide and then the other to receive mill product with the lower passageway of one guide being positioned to receive a length of mill product when the upper passageway of the other is in a lowered position to receive the length.
  • mill product is meant a rolled product produced by Merchant mills and similar mills such as reinforcing bars, small flats, rounds, angles and channels.
  • an improved directing guide comprising, in. combination: right and left mating elongated directing members adjacent each other and pivotedly mounted at the ends thereof adjacent said gathering tables for horizontal and vertical movement of the ends thereof adjacent said delivery tables, each of said right and left directing members having an upper horizontal surface and a lower horizontal surface, outboard vertical surfaces extending upwardly from each of said horizontal surfaces and for the length thereof, and an inboard vertical surface extending upwardly from said upper horizontal surface from the end thereof adjacent said gathering tables to a point less than midway of the length thereof, the outboard vertical surface of said lower horizontal surface tapering from full trough width at the end thereof adjacent said delivery table to zero trough width at a point short of said inboard vertical surface; means for alternately horizontally positioning said right and left elongated directing members to receive lengths of mill product from said delivery table; and means for alternately
  • the delivery guide of claim 1 comprising in addition thereto hinge means for said upper horizontal surfaces adapted to permit swinging each of said upper horizontal surfaces up and away from the center line of said delivery guide to allow access to said lower horizontal surfaces, and top covers for the passageways defined by said upper horizontal surfaces, said top covers being hinged for swinging each up and away from the center line of said delivery guide to allow access to said upper horizontal surfaces.
  • a switching mechanism adapted to direct successive lengths of mill product from a delivery table of a rolling mill alternately to two cooling beds, comprising in combination: right and left contiguous elongated directing members each comprising a lower passageway and an upper passageway directly thereabove, said passageways each having a floor and an outer vertical guide wall with the outer vertical guide walls of said lower passageways tapering from full floor width at the entrance to zero fioor width a distance in the range of /3 to /2, the length thereof and when aligned the lower passageway of one member communicating with the upper passageway of the other member in advance of the point of said zero floor Width whereby mill product can be transferred from the lower passageway to the upper passageway, said right and left contiguous elongated members being pivotedly mounted at the exit ends thereof for vertical and horizon tal movement of the entrances of said passageways; and means for alternately horizontally positioning said right and left contiguous elongated directing members and means for vertically positioning said lower passageways to receive lengths of mill product from said
