Definitions

  • This invention relates to an apparatus for changing the rolls of a rolling mill and is particularly useful in changing the horizontal rolls of a universal beam mill.
  • the present invention provides a car for receiving two pairs of horizontal rolls, one pair being the replacement rolls and the other the rolls that are to be removed from the mill.
  • This car is constructed with a cut-away portion at the side thereof adjacent to the mill so that when the car is in its roll changing position it will pass over the wing rovided for the vertical roll on the operating side of the mill.
  • Means are provided for moving the car perpendicular to a plane containing the axes of the rolls when positioned in the mill so that the rolls removed from the mill can be moved away from the mill, and at the same time a new pair of rolls automatically positioned for insertion into the mill.
  • the invention also contemplates the employment of a roll transferring means which passes through the car when the car is positioned adjacent to the mill to engage one or both of the rolls positioned in the mill, after which the transfer means can simultaneously withdraw the rolls out of the mill and onto the awaiting car.
  • the transferring means is also employed to simultaneously insert the new rolls .into the mill.
  • FIGURE 1 is a plan view, partly in section, of a wide flange beam mill, in connection with which a roll changing apparatus employing the features of the present invention is employed; 7 I
  • FIGURE 2 is an elevation view of the roll changing apparatus shown in FIGURE 1 showing a portion of the mill in phantom;
  • FIGURE 3 is a sectional view taken on lines III--III of FIGURE 1, but with the car of the apparatus shown in a position to one side of the mill.
  • a wide flange beam mill 9 made up to two upright housings 10 formed with spaced-apart windows 11 for receiving a pair of horizontal rolls 12 and 13 and 0ppositely perpendicularly protruding rigid wings-1 and 15 which receive the vertical rolls of the mill, only one of these rolls 16 being shown and that in FIGURE 2.
  • Identical chock-radial bearing assemblies 17'and thrust bearing assemblies 18 are provided for the rolls 12 and 13.
  • the universal beam mill is provided with roll supporting beams 19 and 20 which are located between the chocks 17 of the, horizontal rolls and the pairs of screws 21 and 22 of the mill 9, the drawing (FIGURE 2) only illustrating one screw of each pair.
  • roll supporting beams 19 and 20 are located between the chocks 17 of the, horizontal rolls and the pairs of screws 21 and 22 of the mill 9, the drawing (FIGURE 2) only illustrating one screw of each pair.
  • One of the purposes of these roll supporting beams is to guide and support the chocks during the withdrawal and replacement of the roll assemblies and for which reason it will be noted that the upper beam 19 extends out from one of the housing 10.
  • Roll assembly supporting members 31 are also provided at the bottom of the bays, it being noted that these members are centrally located in each bay; As the drawings show, the roll assembly supporting members 31 are equipped with hearing lined surfaces to facilitate easy movement of the roll assemblies into and out of the car 24.' l V In returning to FIGURE 2, it will be noted that the upright members 25 at the side of the car adjacent the mill 9 assume the shapeyof a C so that when the car 24 is located in the roll changing position substantial portions of the supporting members 29 and the base 26 pass over and under, respectively, the wing 14 of the vertical roll 16.
  • FIGURES 1 and 3 the assembly 34 shown in FIGURES 1 and 3 is secured to one side of the car through which agency the car is traversed along the tracks 33.
  • the car 24 is shown in its inoperative position away from in front of the mill- 9, where it engages a stop 35..
  • a roll assembly retracting and inserting mechanism 36 In conjunction with a roll'changing car there is provided a roll assembly retracting and inserting mechanism 36.
  • This mechanism consists of a C-shaped frame 37 whereby an opening is provided so that when brought into a position adjacent to the mill 9 it will'pass around the wing 14 of the vertical roll 16.
  • a hook 38 To the upper part of the frame 37 which is made to assume an elevation coincident with the axis of the upper roll 12, there is provided a hook 38 which engages a complementary hook 39 formed on the end of the chock 17 of theupper roll 12.
  • a similar hook 40 is provided at the lower portion of the frame 37 which cooperates with a hook 41 formed on the chock 17 of the lower roll 13. Each hook is ing surfaces during the roll inserting operation.
  • hooks 38 and 46 are pivotally mounted on the frame 37 chocks 17.
  • the roll retracting and inserting mechanism 36 is carried by a base 44.
  • the base isprovided with parallelly arranged spaced-apart guide ways 45 into which there is received feet 46 of the mechanism 36.
  • Similar guide ways 47 and 48 are provided in each of the bays' 27 and 28 of the car 24 which serve as extensions of the guide ways 45.
  • the feet 46 and the guide ways 47 are shown 1n their cooperative relationship'in FIGURE 3, where being also noted that the guide ways 47 and 48 are arranged on either side of the chock supporting members 31.
  • the C-shaped frame 37 is adapted to be slid through either of the bays 27 or 23 of the car 24 to a position shown in phantom in FIGURE 2.
  • the movement of the frame 37 is effected by a piston cylinder assembly 49 which is connected to the back of the frame. as shown in FIGURES 1 and 2.
  • the piston cylinder assemblies 34 and 49 have sufficient strokes to perform the necessary movements of the car 24 and 'C-shaped frame 37, respectively, although the several different positions of these elements may be ob- 'tained if desired, by providing retractable stops that will predeterminately position the car and frame in their desired positions.
  • the chocks 17 of the roll assemblies will be supported by the beams 19 and 20.
  • the front chocks-pass clear of the beams as to the upper one, its lower surface will come into engagement with the supporting members 29, and as to the lower one, its lower surface will slide onto the extensions 23 and then onto the supporting member 31 of the car.
  • the back chocks of the, roll assemblies pass out of the mill they, too,'will engage the aforesaid members.
  • the rolls will continue to be moved out of the mill until they assume a position that coincides with the new rolls 12a and 13a shown in FIGURE 2, after which the operation of the cylinder 49 will be interrupted so that the hooks 38 and 40 may be raised out of engagement with the hooks 39 and 41 of the roll assemblies. Following this the piston cylinder assembly 49 will again be activated to further retract the C-shaped frame 37 to the inoperative position shown in FIGURE 1.
  • the piston cylinder assembly 34 will be operated for the second time to move the car 24 so that its bay 28 with the roll assemblies 12 and 13 is moved toward the top of the drawing as one views FIGURE 1 to a position but from in front of the mill 9.
  • this movement will result in the bay 27 and, hence, the new roll assemblies'lZa and 13a, being positioned directly in front of the mill.
  • the rolls of this mill can be changed at the same time that the rolls are changed in the universal mill.
  • the piston cylinder assembly 34 could, if desired, be used to automatically position the respective bays of the two cars in the desired positions.
  • An apparatus for use in changing rolls of a rolling mill having at least two rolls, comprising a roll carrying car, upright members carried by said car forming two bays, two platforms mounted on said car in each of said bays, each for supportinga roll, two platforms mounted on said upright members, each for supporting a roll, said platforms of said car being arranged coplanar to one of the rolls when positioned in the mill, said platforms of said upright members being arranged coplanar to the other roll when positioned in the mill, means for positioning the car so that one or the other of said bays is located adjacent to said mill, said bays having opposite open sides, roll moving means arranged on the side of said car opposite the mill, means for moving said roll moving means into and out of said car for removing the rolls from the mill onto said car and from said car into the mill, and means on said roll moving means for engaging the rolls.
