Definitions

  • This invention relates to rolling mills.
  • the objects of the invention are the provision of roll housings,iin ⁇ which ,two or more fsetsV of co-operatingrolls of different sizes may be mounted; the provision of means for positivelyco'nnecting the .rolls's'o thatthey ⁇ vvill always turn in exact'synchronisinigsineans for adjusting :and locking'the rolls improper circumferential registry; and ineansfor feedingblanks, tothe rollsat ⁇ different speeds, according to; theisize andshape of vcross section of :the finishedipart ⁇ being rolled.

  • rolling articles-such as -erowbara for example, Where the cross section of the finished article varies considerably at different points, as, ⁇ for example, the head of the crowbar compared with the end of the tapered handle, it is advantageous to vary the feed of the hot metal bar or blank which is supplied to he finishing rolls for forming the article being manufactured.
  • vFor this purpose I provide a feed mechanism controlled by an electric motor, which is driven at varying speed, in accordance with the cross sectional changes of the finished article being formed.
  • the feed motor is driven rapidly, so as to push the hot blank into the rolls to aid in supplying a sufficient amount of metal for that portion of the crowbar.
  • the motor is driven slower, so as to feed metal to the rolls at a reduced speed, aboutv the speed of the rolls if the cross sectional area of the octagon portion is substantially equivalent to the cross sectional area of the l bar being fed.
  • Fig. 1 shows an end View of the roll stand, one of each of the pairs of supports 4 and 5 being seen. It will be understood that similar supports 4 and 5 are situated at the other end of the roll stand, directly behind the members 4 and 5 in this figure.

  • T e shaft 12 is extended toan outer bearing 25, mounted on the concrete foundation 1.
  • the shaft 12 may be driven in any desired manner, as by a belt on pulley 26. A geared connection to a motor or any driven shaft may be used.
  • the upper roll 11 is supported by cross members 27, exactly similar to the members 21, above described. Flanges 22 fit into the upper set of opposite notches 9, and retaining plates 28 are bolted on to the frame, and to the members 27, t0 hold the support in proper position.
  • Journal boxes 29 enclosing bearings 30 for shaft 13 are supported on coil springs 31, which rest at their lower ends on cross members 26,.as shown clearlyin Figs. 1 and 3.
  • the upper sides of the journal boxes 29 rest against the lower ends of abutment members 32, threaded in thecross frame members 6, and held in rigid relation thereto by locking nuts 33, as Y shown in Fig. 3.
  • This manner of mounting the bearings of shaft 13 permits an accurate adjustment of the roll 11 to contact with the roll 10, as will be obvious.A
  • the rolls may be adjusted axially to secure proper vertical alignment of the shaping grooves by means of set screws 28a mounted in plates 28 and having their inner ends contacting against the bearings of v*the roll shafts, as shown in Figs. 1 and 3.
  • notches 9 are provided at such intervals, as to accommodate a number of different, sizes of rolls. As shown in the drawings, notches are provided for use with a set of rolls of exactly one-half the diameter of the rolls 10 and 11.
  • the support 2O is built up by blocks or otherwise to bring the journal boxes up to the new position of ⁇ the transverse supports 27 to the set of notches 9 just below that in which they are illustrated in Figs/1 and 3, and the abut-y ment screws 32 are turned downto the new position, until the roll faces are held in proper Contact.
  • the feeding mechanism operates ⁇ on. the same level as with the first set of rolls.
  • web also has a 'concentric segmental slot 45, as shown i'nFig. ⁇ At each end of this slot there is a projection orrraised lug 46, through which there is a threaded hole in which is mounted a setscrew 47.

  • the web 49 of this wheel has curved concentric slots 50 adapted t0 receive bolts 44 above described. and a raised lug l51 adapted to extend through'the curved slot '45 in web 43, when the gear wheel is placedin position on the sleeve 41, as shown in Fig. 7.
  • the adjusting screws 47 are adapted to bear upon the sides of lug 51, and byadvancing one screw and retracting the other, the lug may be adjusted to any desired position within ⁇ the limits of its travel in slot 45.
  • FIG. 2 diagrainmatically represents means for controlling the speed of motor M. and consequently of the feedrolls 53 and l59. 'to correspond to variations inthe cross section of the finished article being formedby rolls 10 and 11.
  • lInthis diagram A. represents the armature and F represents the field of electric motor M, above referred to.

Branches L and K lead from wire H to Contact brushes M and N, adapted to connect with the segmental contact segments D and E respectively, during certain parts of a revolution of the plate 1).
  • r he circular contact B is permanently connected to the segmental contact C, which in turn has permanent connections to contact segments D and E.

  • rllhe concrete foundation will ordinarily furnish suiiicient insulation between the two metal roll frames, but if desired the frame 60 may be mounted on a nbre mat TO and the bolts holding the frame to the concrete suitably insulated in well known manner.
  • the wires S and T may be connected to the rolls l() and 59 direct by brushes on the shafts. But ordinarily this is not necessary.
  • I provide a roll stand in which finishing rolls of various sizes may be mounted, the change being easily made. Also means for positively driving both rolls of the pair by a geare connection, which insures continuous registering of the roll faces in a definite relation to each other. Also adjustable means for turning one of the rolls without removing it from its bearings, to secure proper initial registering of the surfaces; and also means for varying the feed during a part of each revolution of the finishing rolls.
