Definitions

  • ABSTRACT Cross roll carrier frames are rotatably supported [50] Field of Search 72/99, 162, in the to frame housing A pair f Spaced manually operated 102, 109, l 11, 235; 74/895; 287/1 screws engage each frame on either side of the centerline of the frame with one screw adjusting the frame in one direction [56] References Cited and the other screw locking the frame in its adjusted position. UNITED STATES PATENTS The operation of the screws is reversed for adjustment in the 558,591 4/1896 Medart 72 /99 other direction.
  • This invention relates to cross roll machines and, more particularly, to an improved angular adjusting and locking means for the cross rolls in a cross roll straightener.
  • Cross roll machines typically are employed for straightening, polishing or derodding round bars or tubes.
  • cross roll machines comprise cooperative pairs of angularly disposed rolls with each roll being rotatably supported in a roll carrier frame.
  • the roll carrier frames are normally adapted for angular adjustment and at least some of the frames may be vertically adjustable to vary the distance between the rolls thereby to accommodate stock of various dimensions.
  • the vertical and angular adjustment of the roll-carrying frames is necessary not only to accommodate tubes and bars of varied dimensions but also to achieve the optimum amount of cross roll contact on the periphery of the workpiece for good straightening, polishing or derodding without spiral marking of the workpiece.
  • a second approach employed by the prior art has been the use of a hand wheel-operated threaded screw which traverses a nut that is connected to the carrier frame and causes the frame to be displaced angularly.
  • a third prior art approach employs a cam follower in the form of a bell crank with one end of the bell crank disposed in a slot in the carrier frame and the other end of the bell crank cooperating with a screw-adjusted yoke to cause angular displacement of the frame.
  • the fourth approach employed by the prior art is related to the first described approach and involves a wrench operated eccentric pin which slidably and rotatably engages the carrier frame with the eccentricity of the pin causing the frame to be rotated.
  • Still another object of this invention is to provide an angular adjusting mechanism for cross rolls which is of simple construction and which can be readily understood and easily applied by the machine operator.
  • a further object of this invention is to provide a cross roll adjusting mechanism in which the rolls are locked in their final position by the same means as that which is used to achieve the angular adjustment of the rolls, thereby reducing set up time for the machine.
  • this invention contemplates cross roll carrier frames having cylindrical portions which are rotatably supported in cylindrical bores in the roll frame housing.
  • cylindrical frame and consequently the cross roll mounted, thereon is rotated angularly within the desired angular limits by means of two adjusting screws which engage spaced planar surfaces on the cylindrical portion of the frame.
  • One of the adjusting screws is mounted on one side of the center line of the rotatable carrier frame while the other screw is mounted on the other side of the center line.
  • the cylindrical frame is caused to rotate in one direction while advancing the other of the screws will cause the roll frame to rotate in the opposite direction.
  • one screw functions as a pusher screw while the other screw opposes rotation of the frame and acts as a locking screw to maintain the angular adjustment of the cylindrical frame.
  • One of the adjusting screws employs a vernier indicating means so that precise adjustment of the angular position of the rolls may be achieved.
  • FIG. 1 is a front elevational view of a cross roll machine incorporating the principles of this invention
  • FIG. 2 is a top plan view of the machine of FIG. 1;
  • FIG. 3 is a sectional view along line 3-3 of FIG. 1;
  • FIG. I there is illustrated a cross roll machine, indicated generally by the reference numeral 10, which incorporates the principles of this invention.
  • This cross roll machine comprises a base I2 on which there is supported the cross roll mechanism, much of which is conventional and forms no portion of this invention so will not be described in detail herein.
  • Supported on the base 12 is a cross roll unit indicated generally by the reference numeral 14.
  • This cross roll unit includes an upper housing 16 and a lower housing 18 with the upper housing being spaced from the lower housing by support columns 20.
  • a plurality of upper cross rolls 22 and a lower cross rolls 24 are supported in the housing in a manner which will be described in more detail hereinafter.
  • the pairs of upper and lower cross rolls cooperate to define a cross roll pass as is well understood in the art.
  • FIG. 3 there is illustrated a sectional view through a pair of the cross rolls and illustrates the manner in which each of the upper and-lower cross rolls 22, 24 is supported in their respective housings.
  • the upper cross roll 22 is rotatably supported in roll neck bearings 26 which depend from the lower end of a cylindrical roll frame 28.
  • the roll frame is received in a cylindrical bore 30 in the upper housing 16.
  • a drive shaft 32 and universal joint 34 connect the upper roll 22 with a source of power such as an electric motor 36. Similar drive means would be provided for each of the other rolls 22, each of which would also be supported in the manner illustrated in FIG. 3.
  • each roll frame 28 includes a bore 46 into which there is threaded a shaft 48.
  • the shaft 48 includes a hand wheel 50 secured to the upper end thereof. It will be appreciated that as the hand wheel 50 is rotated, the shaft 48 will also rotate causing the roll frame 28 to move vertically within the bore 30 thereby raising or lowering the upper roll 22.
  • Appropriate indicia means 52 may be associated with each of the hand wheels 50 thereby to provide an accurate means for controlling the adjusted position of the upper rolls.
  • FIG. 3 A similar arrangement is provided for the middle lower roll 24.
  • This arrangement is illustrated in FIG. 3 wherein a hand wheel 54 mounted on the base 12 drives a shaft 56 which in turn drives a pair of gears 57, 58 to rotate a thread shaft 59 carried in the roll frame 40.
  • This broad arrangement of an adjustable middle cross roll with vertically fixed end rolls is conventional in the art and is not intended to form any part of the invention.
  • the roll frame 28 includes a pair of recesses 61, 62 formed in the periphery of the frame.
  • recess 61 is offset to the left of the centerline or axis of rotation of frame 28 while recess 62 being offset to the right of the axis of rotation.
  • Both recesses are identical in configuration, with recess 61 including a planar or fiat abutment surface 64 and recess 62 having a flat abutment surface 65.
  • the two surfaces 64, 65 are coplanar with the plane of these surfaces being parallel to the centerline of frame 28.
  • a pair of adjusting screws or threaded shafts 66, 68 is threaded into replaceable bushings 63 secured in the housing 16, with the one adjusting screw 66 being aligned with the recess 61 while the other screw 68 is aligned with the recess 62.
  • a knob or handle 67 is associated with the adjusting screw 66 and a corresponding knob or handle 69 is connected to the adjusting screw 68.
  • the two adjusting screws 66, 68 are offset from the longitudinal centerline of the roll frame 28 with the adjusting screw 66 being positioned on one side of the centerline and the adjusting screw 68 spaced an equal distance on the opposite of the centerline.
  • the inner end of each screw 66, 68 is hemispherical in configuration and cooperates with a shoe 67, 69' carried on the outer end thereof to form a swivel connection for a purpose hereinafter described.
  • a locknut 70 is threaded over the one adjusting screw 66 while the other adjusting screw carries a collar 71.
  • the collar 71 has appropriate indicia inscribed thereon and is telescopically received over a collar 72 formed on one of the bushings 67. indicia are also inscribed on the collar 72 with the two collars cooperating to function as a vernier micrometer arrangement.
  • the described adjusting mechanism operates in the following manner.
  • one or the other of the adjusting screws 66, 68 will be threaded to be longitudinally advanced inwardly while the other will be threaded to be withdrawn outwardly.
  • the adjusting screw 66 will be rotated to be withdrawn from engagement to surface 64.
  • the other adjusting screw 68 will be rotated to advance inwardly with the shoe 69' cooperating with surface 65 to rotate the frame 28 within the bore in a counterclockwise direction.
  • the amount of rotation imparted to the roll frame 28 may be measured by the vernier scale associated with the adjusting screw 68.
  • locknut 70 may be threaded down, thereby locking the screw 66 in position. ln this condition, the roll frame 28 is restrained from angular movement in either direction by the cooperation of the two adjusting screws with the surfaces 64, 65 and the roll frame 28.
  • the adjusting screw 66 will act as a pusher screw to rotate the roll frame in that direction, while the adjusting screw 68 will be withdrawn to permit the angular rotation.
  • one of the two screws acts as a pusher screw while the other of the two screws acts as a lock screw.
  • the swivel connection between the shoes 67, 69 and the screws 66, 68 permit the angular rotation of the roll frame while retaining firm engagement between the shoes and the surfaces 64, 65.
  • the elongated configuration of the recesses 61, 62 permits vertical adjustment of each of the cross rolls while retaining their angular adjustment. In this manner, the angular position of the rolls may be set and the machine may be adjusted to accommodate various diameters of stock without altering the angular settings.
  • the swivel connection between the shoes and screws may be of varying constructions.
  • One specific construction is illustrated in FIG. 5 and comprises an enlarged head 68a of a convex configuration cooperating with a concave surface 690 in the shoe 69".
  • a suitable retaining ring may be employed to retain the shoe assembled to the screw while permitting the desired swiveling action.
  • the invention provides a means for achieving a minutely precise angular adjustment of each of the individual cross rolls.
  • the mechanism incorporates means for positively locking each cross roll in its adjusting position while at the same time permitting vertical adjustment of the cross rolls.
  • the adjusting mechanism is simple in operation and may easily be employed by the machine operator.
  • the vernier depth indicator readout markings associated with the adjusting screw provides a means whereby the final angular positions of the cross rolls can be recorded for satisfactory roll setting on specific tube sizes and types. Thereafter, the same roll settings can be quickly and precisely duplicated for similar tubes, thus reducing setup time and eliminating scrap losses.
