Definitions

  • FIG. 5 is an enlarged, fragmentary vertical sectional viewc'orresponding generallyto the line 5-5 of FIG. 2 I v I
  • FIGJ6 is a fragmentary sectional view corresponding generally to line 6-6 of FIG. 5,
  • FIG. 9 is an enlarged fragmentary sectional view generally corresponding to the line 99 of FIG. 4,
  • a table 34 in the form of a flat plate and preferably having a shape best seen in FIGS. 4 and 8.
  • the table 34 is supported for orbital movement by linkage mechanism supported from the side wall of the casing 31.
  • a sub-support 35 has opposite sides 3636 and an end 37 firmly bolted to pads 38 which extend inwardly of three walls of the casing 31 and are securely fixed to such walls, as by welding or the like.
  • two limit switches 160, 161 are secured by brackets to the undersurface of the fixed sub-support 35.
  • the limit switches are diametrically opposed and are adapted to be selectively engaged by a downwardly extending finger 162 carried by the track 110.
  • the limit switches 160, 161 are connected in electrical circuit with the motor 100 which rotates the shaft 93.
  • the finger 162 is shown in FIG. 5 as in engagement with limit switch 160 and the motor 100 will rotate the shaft 93 in the direction of the arrow 163 seen in FIG. 4.
  • the follower wheel 70 is urged by the force of the weight 122 in the direction of the force component 182.
  • the follower is rapidly moved to and fro in the direction of the movement of the plate 111 along the track 110, this movement being back and forth along the line shown by the arrow 182.
  • This causes the table 34 to move in the same direction and in the same amount, and since the grinding wheel 66 is carried by the table, it therefore moves to and fro in exact accordance with the follower wheel.
  • FIG. 14 shows the position of parts after the shaft 93 and the track 110 have been rotated 90.
  • the follower wheel 70 is now at the midpoint of the groove in the master roll 81 and will respond to the changing diametrical curvatures of the groove, and will move to and fro along the line shown by the arrow 182.2, to cause a corresponding movement of the grinding wheel in the manner set forth above.
  • the grinding wheel may be moved a slight amount toward the axis of the master and work rolls (by adjustment of the slide 59 shown in FIG. 3) and a subsequent pass of the grinding wheel, in the manner hereinbefore stated, will finish grind the groove in the work roll to the exact contour of that in the master roll.
  • a rotatable shaft carried by said base and having connection with said table means whereby rotation of said shaft effects shifting of said table in a plane
  • said follower means being moved toward and away from and laterally of the axis of said master roll through engagement with the contour surface of said groove in said master roll and translating such movement to said cutter means through said table means so that said cutter means duplicates such groove in said work roll,
  • Apparatus for duplicating the contour of a nonuniform peripheral groove of a master roll in the periphery of a work roll comprising:
  • connection means between said table means and said base for supporting said table means for planar movement relative to said base
  • a rotatable shaft carried by said base and having connection with said table means whereby rotation of said shaft effects shifting of said table in a plane
  • top closure has a rim to provide a tray for collecting said cutting liquid.
  • Apparatus for duplicating the contour of a nonuniform peripheral groove of a masterroll in the periphery of a work roll comprising:
  • connection means between said table means and said base for supporting said table means for planar movement relative to said base
  • a rotatable shaft carried by said base and having connection with said table means whereby rotation of said shaft effectsshifting of said table in a plane
  • said follower means being moved toward and away from and laterally of the axis of said master roll through engagement with the contour surface of said groove in said master roll and translating such movement to said cutter means through said table means so that said cutter means duplicates such groove in said work roll.
  • Apparatus for duplicating the contour of a nonuniform peripheral groove of a master roll in the periphery of a work roll comprising:
  • Apparatus for duplicating the contour of a groove of a Pilger roll in the periphery of a roll blank comprising:
  • follower means and cutter means mounted on said table in spaced relation, said follower means being cooperable with said Pilger roll and movable toward and away from the axis thereof, and said cutter means being cooperable with said roll blank and movable toward and away from the axis thereof,
  • connection between said vertical shaft and said table comprising parts relatively movable along a horizontal line, one part being connected to said shaft and the other part being connected to said table,
  • said follower means responding to the varying groove contour presented to it by the rotating Pilger roll to counteract the force of said urging means and thereby be rapidly moved to and fro along the horizontal line of said relatively movable parts, to cause said table to move in the same direction and in the same amount, and therefore move said cutting means in exact accordance with said follower means.
  • connection between said vertical shaft and said table comprises,
