Definitions

  • While the present invention may have utility in generally all types of rolling mills, and for that matter machines used to process paper and rubber, it immediately commends itself to certain types of rolling mills employing roll-chock supporting beams which extend between the vertical housings and on which the chocks of various length rolls are longitudinally positioned.
  • roll-chock supporting beams which extend between the vertical housings and on which the chocks of various length rolls are longitudinally positioned.
  • minimum length rolls may be always employed, notwithstanding the fact that a wide range of varying width products, such as beams and plates, are to be rolled.
  • An exemplary mill of this type is disclosed and described in M. P. Sigers copending US. application Serial No. 146,580 filed October 20, 1961, now Patent No. 3,212,314.
  • the present invention provides an apparatus that will automatically and without manual assistance register one or more rolls of the mill in a predetermined roll changing position.
  • it provides for automatically disengaging the chocks from the rolling load transferring surface of the beam and positioning the chocks on supporting surfaces formed thereon, after which the chocks and roll can be rapidly moved onto an awaiting roll changing rig, if one is being used.
  • the apparatus herein disclosed is very economical to install and operate and has the additional significant advantage of readily cooperating with existing mill components.
  • FIGURE I is an outside elevational view of a universal wide flange beam mill which incorporates the features of the present invention
  • FIGURES 11a and b constitute composite sectional views of the upper half of the mill shown in FIGURE I, the right-hand elements in section being illustrated in the position they assume during operation of the mill, and the left-hand elements in section being illustrated in the position they assume during the roll changing operation,
  • FIGURE III is a sectional view taken on lines III-III of FIGURE II.
  • FIGURES IV, V, and VI are three elevational sequential views, which when considered with FIGURE II represent the respective positions assumed by the illustrated elements when the mill is brought from an operative position to a roll changing position.
  • a universal beam mill 10 having a pair of vertically arranged housings 11 and 12, the housing 11 being only 3,266,282 Patented August 16, 1966 shown in FIGURES I and II, while both housings can be seen in FIGURE III.
  • the housing 11 is provided with a window 13 into which is received for vertical adjustment therein, a pair of horizontally arranged cooperative rol-ls 14 and 15, each having a pair of opposed bearing-chock assemblies 16, hereinafter referred to simply as chocks, arranged on the opposite journals of the rolls.
  • the housing 11 includes a cross frame 17 which receives one of the two vertical rolls 118 of the mill, the other frame and vertical roll not being shown. Since the illustrated embodiment of the invention is shown only in relationship to the roll 14, further cornment on the rolls l5 and 18 will not be given.
  • the roll 14 is adjusted vertically by a pair of conventional screwdown screws 20, as shown in FIGURE II, one provided for each housing.
  • the bottom of the screw engages a transversely extending top roll-chock supporting beam 21 that extends between and moves vertically relative to the housings 11 and 12.
  • This beam which receives the rolling loads from the chock 16 and transmits them to the screw, has a central elongated portion 22, which can be best seen in FIGURE II, including a lower, flat, load bearing surface 23 having formed thereon opposite parallel extending chock supporting and guiding ledges 24.
  • the upper portion of the chock 16 is provided with centrally flat load transmitting horizontal surface 25 that engages the surface 23 of the beam as can be seen in FIGURES II and IV.
  • the chock has opposed inverted L-shaped projections 26, the horizontal portions 27 of which engage with the chock supporting ledges 24 of the beam 21.
  • a balance piston cylinder mechanism provided for the roll 14 is shown in FIGURES I and II and includes a hydraulic piston cylinder assembly 28 which is mounted at the top of the mill housings 1.1 and 12. To the piston rod of the piston cylinder assembly, a pair of roll balance carrier bars 29 provided for the chock are secured by a cross bar 30. The bars 29 extend downwardly through openings 31 provided in the beam 21 as shown in FIG- URE II. The lower ends of these carrier bars have oppositely arranged hooks 32 which engage correspond ing hooks 33 formed on downwardly extending bars 34. As shown in FIGURE II, the bars 34 pass through the chock 16 and are connected to a bearing cap 35 which engages and supports one of the journals of the roll 14. By the interconnection of the bars 34 and the carrier bars 29, the chock 16 is urged against the bottom of the screw 20 thereby to define the roll pass position of the roll 14.
  • the present invention has reference in the preferred form to providing a mechanism for automatically positioning the beam 21 and, hence, the roll 14 in a predetermined vertical location for quick removal of the roll 14 and as an adjunct thereto for automatically disengaging the rolling load transfer surface 25 of the chock 16 from the surface 23 of the beam 21, at the same time causing the portions 27 of the chock to engage the ledges 24 of the beam 16 and causing the hooks 32 and 33 to separate.
  • these elements and surfaces will again engage or disengage each other as the case may be.
  • the pair of carrier bars 29 are provided at their opposite ends with a pair of upwardly extending projections 37 each having their upper ends formed into a U-shaped portion 38, as best shown in FIGURE III.
  • a general horizontally disposed lever 39 which is connected to the projection 37 by a pin 41, the lever extending in a direction substantially perpendicular to the carrier bars 29.
  • each lever is formed with a long and short arm, the short arm being located adjacent to the housing 11 and having an upper rounded surface which projects below a lug 42 formed on the beam 21, the lug being identified in FIGURES IV-VI.
  • the levers '39 pivot the rounded surfaces of their short arms are brought into engagement with the lugs 42.
  • each lever 39 is similarly rounded at its upper end, in which this end cooperates with a lug 43 formed on the housing 11 and located in the window 13 thereof so as to be engaged by the rounded portion of the long arm when the lever is raised to its upper position as in FIGURES III, IV and V.
  • the housing at the top of the window is provided with stop surfaces 44 which are engaged by the upper surfaces of the lugs 42 of the beam 21 when the beam has been raised to its upper position. This condition is shown in FIGURE VI.
  • the aforesaid elements of the roll positioner are as indicated at the right-hand side of FIGURE II.
  • the surface 25 of the chock 16 is against the surface 23 of the beam 21, portions 27 of the chock 16 are out of engagement with the ledges 24 of the beam and the hooks 32 of the carrier bars 29 are in positive engagement with the hooks 33 of the bars 34.
  • the roll assembly may be quickly slid over the supporting surfaces of the ledges 24 of the beam 21 and onto an awaiting roll changing rig, not shown.
  • the extending projection of the beam 21 shown to the left of FIGURE III will permit at least the adjacent end of the roll to pass out of the window of the housing before it is necessary for the roll changing rig to support it.
  • a device for positioning said roll in said roll changing position comprising:
  • a chock supporting beam arranged between the roll and said roll moving means having a supporting surface engageable by said chocks when said roll is brought into said roll changing position
  • a housing for rotatably receiving a pair of rolls that form a roll bite, one roll being adjustable relative to the other,
  • a device for predeterminately positioning and supporting said adjustable roll in said roll changing position comprising:
  • a piston cylinder assembly including a pair of connecting links for each chock engageable with said chocks to urge said chocks and beam in a direction of said screws,
  • levers having long and short arms
  • means on said housing engageable by said beam to interrupt its movement in the direction of said screws to predeterminately position said roll in said roll changing position.
  • a device for positioning and supporting the bearing chocks 16 of one of said rolls 14 in a predetermined position for removal of the roll said device including a beam 21 for supporting said bearing chocks 16 of said one roll when said bearing chocks are brought to said roll removal position,
  • a movable bar 29 selectably engageable with said hearing chocks 16 of said one roll thereby to place said bearing chocks 16 of said one roll into two positions relative to said beam 21, in which in one position by virtue of the bar said bearing chocks 16 are carried by the bar and urged against said beam 21, and in said second position by virtue of said bar said hearing chocks 16 are free of said bar and supported by the beam 21,
  • said beam 21 has bearing chock supporting surfaces 24 engageable by said bearing chocks 16 and wherein said beam 21 is disposed between said bearing chocks 16 and said means 28 for moving said bearing chocks, and
