  • MORGAN ETAL ROLL ADJUSTMENT MEANS Filed Sept. 24, 1962 7 Sheets-Sheet 2 1208374303 Mazes Mar am, WM d1. ,Jz by W, 64% #f/wmfi fli'i'orflqys Q0 mm March 9, 1965 M.
  • adjust-intent is achieved through the use of screwdown devices which in the case of horizontal rolls control the distance of separation between the upper and lower rolls.
  • screwdown devices which in the case of horizontal rolls control the distance of separation between the upper and lower rolls.
  • eccentric means are disclosed for shifting the vertical position of the links with respect to the upper rolls, thereby varying the distance between the rolls by vertically displacing the lower roll. This means of adjustment has been found entirely satisfactory both as to accuracy of control and ease of operation. It suflers, however, from the same disability found in the prior art in that the vertical position of the pass line changes as the lower roll is moved up and down with respect to the upper roll.
  • the present invention is directed toward providing a new and novel mechanism which may be utilized with the link structure of Wilson Patent No. 3,055,242 to produce equal and opposite movement of the rolls during adjustment, thereby enabling the pass line to remain at a constant level.
  • eccentric mechanisms are provided to act in conjunction with the links carrying the lower roll and the upper roll supporting trunnions, whereby as the eccentrics are rotated to cause the required adjustment, the upper roll will be raised or lowered with respect to the roll housing or frame and the links will be lowered or raised with respect to the upper roll through a distance which is twice the distance the upper roll is raised or lowered. This results in equal displacement of both rolls in opposite directions toward or away from the pass line.
  • a second aspect of the present invention is the inclusion of two additional eccentrics positioned within the roll adjusting eccentrics in such manner that, upon rotation of the inner eccentrics, coarse adjustment of the rolls may be quickly made to provide for the major adjustment in roll spacing necessitated when roll changes are made in which the new rolls are of greater or lesser diameter than the replaced rolls. Since the upper and lower rolls are always of equal diameter, although possibly of diameters different from the rolls previously used, adjustments made according to the present invention will cause the pass line to remain at a constant level. Hence it is unnecessary to make any adjustment of the pass guides when roll changes are undertaken. It is to be appreciated, however, that the coarse adjustment eccentrics may be omitted in those cases where any required adjustment of the rolls will fall within the scope of the fine adjustment eccentrics. Thus it will be understood that the fine adjustment eccentrics may be used either with or without the inclusion of the coarse adjustment eccentrics.
  • the coarse adjustment eccentrics are utilized to impart quick coarse adjustment to the rolls, they operate on the same principle as that of the fine adjustment eccentrics; namely, the upper roll is moved up or down one unit with respect to the supporting housing or frame while the links that carry the lower roll are simultaneously lowered or raised two units in an opposite direction.
  • a major object of the present invention is to provide means for imparting precise and known adjustments to rolls supported by the frame and links structure of Wilson Patent No. 3,055,242 while maintaining the pass line at a constant level.
  • a further object of the invention is to provide an arrangement of eccentrics such that one unit of angular rotation of the fine adjustment eccentrics will result in one unit of linear separation or closing of the rolls over the full extent of adjustment required.
  • a further object of the invention is to provide novel means for actuating the adjusting eccentrics whereby the upper and lower chocks at the work and drive sides of the housing may be adjusted independently. In this way, the parallelism of the rolls may be controlled at will but without changing the vertical level of the pass line.

  • Rotation of adjusting arms 28 and 30 about upper trunnions 16 and 18 will cause corresponding rotation of both pairs of connected eccentrics on their respective trunnions.

  • first eccentrics 20 and 22 are rotatably contained within collars 24 and 26 which reside. at a fixed vertical level, their rotation will result in vertical displacement of the upper trunnions 16 and 18. This in turn will cause the vertical displacement of the upper chock 12 which rotatably supports the work side of upper roll 2. At the.

  • fourth eccentrics 102 and 104 have been rotatably positioned between upper trunnions 16 and 18 and second eccentrics 32 and 34. It should be noted at this time that rotation of the inner coarse adjustment third and fourth eccentrics by manual or mechanical rotation of end plates 110 and 112 does not cause or require rotation of the fine adjustment first and second eccentrics. Instead, it is intended that units 106 and 108 rotate independently of the first and second eccentrics.
  • FIGS. 9 and 10 illustrate the effects resulting from rotation of the third and fourth eccentrics of unit 106 about upper trunnion 16 through angles of 90 and 180.

  • rotation of both units 106 and 108 carrying the third and fourth eccentrics will result in links 36 and 38 being vertically displaced through twice the distance of the vertical displacement of upper trunnion 16 and in the opposite direction. Consequently, the upper and lower rolls 2 and 4 will be equally displaced in opposite directions without disturbing the vertical position of the pass line PL.
  • first and second eccentrics do not have a common bore and must, therefore, be separate so that they may shift laterally of each other as the units 106 and 108 bearing the third and fourth eccentrics are rotated therewithin.

  • a snugly fitting key 127 in the form of a cylindrical button is placed in the keyways. This permits the eccentrics to shift laterally with respect to each other but compels simultaneous and equal rotation under the movement of arm 28.

  • Curves 124 and 126 represent the maximum opening of the rolls and 120 and 130 the minimum opening obtainable through rotation of the third and fourth eccentrics. It should be noted that the third and fourth eccentrics can be efficiently utilized throughout an entire of rotation about the upper trunnions by radially sub-dividing adjusting end plates 110 and 112 as at 130 into units of varying degrees in order that any one unit of angular rotation will produce a constant unit of vertical roll displacement.
