Definitions

  • My invention relates to rolling mills and particularly to that type of rolling mills in which there is employed a'plurality of rolls arranged in sets, the rolls of one set being parallel to each other, but at a right angle to those of the other set, and in which furthermore, each roll is provided with a plurality of grooves or equivalent operating portions, the purpose being to bring difierent operating portions of the sets of rolls into operative relation as desired by moving the rolls of both sets axially.
  • This neces'sity for adjusting the rolls of both sets i "olves a complication and increased cost, d it is the object of my present invention to avoid this difficulty and to provide a construction in which the adjustment of the rolls is greatly simplified.
  • the-,rolls of one set are journalled in stationary bearings, but the rolls of the other set are j ournalled in a frame movable for adjustment, in a direction which is oblique to the direction of the rolls of both sets.
  • Fig. 1 is a front elevation of my improved rolling mill, with parts in section;
  • Fig. 2 is a diagrammatic plan View showing the relation of the two sets of rolls;
  • Fig. 3 is a diagrammatic front elevation showing only the rolls, in a position corresponding to that of Fig. 1, and
  • Figs. 4 and 5 are diagrammatic views showing the rolls in two other operative positions.
  • the rolls 1 are shown as rotating about horizontal axes, while the axes of the rolls 2 are vertical.
  • I will refer to these rolls as horizontal and vertical rolls respectively, but it ill be understood that Ido not thereby res riot myself to this particular position,
  • the two horizontal rolls 1 are superposed and journalled in suitable stationary bearings-1'.
  • the vertical rolls 2 are arranged in a diiferent vertical plane from the horizontal rolls 1, and as indicated in Fig. 1, thevertical rolls are journalled in suitable bearings in a frame or slide 3 ,movable along a guide or track 4 which extends obliquely both to the horizontal and to the, vertical, or in other words, obliquely to the direction of the axes of both sets of rolls.
  • Each of'the rolls 1, 2 is provided with a plurality of operating grooves or portions, those of the vertical rolls being indicated at a, b, a and those of the horizontal rolls at d, e, f.
  • the frame or slide 3 may be shifted along the track or guide 4 in any suitable manner, for -instance by means of a spindle 5 held against rotation but mounted to slide lengthwise in a suitable bearing 5.
  • This spindle has a screwthreaded portion inmesh with a corresponding internal screwthread on a Worm wheel 7 mounted to rotate in said bearing but held against or operating portion e of the horizontal rolls. 7
  • the line B indicates the path which the blank will take when the rolls are adjusted to the position shown in Fig. 4, and dotted lines indicate the position of the vertical rolls with such adjustment. If the slide 3 is moved down, as indicated in Fig. 1 by the arrow extending from a to f, the operating groove or portion a of the vertical rolls 2, at the point where they are closest together,
  • the three grooves a, b, 0 are alike and the grooves d, e, f likewise are alike.
  • the grooves a, b, c (and the grooves d, e, 7) might be of difl'erent size or shape as desired for the progressive treatment of the blank in a plurality of passes.
  • these grooves might be graduated in size, so that the blank would first be passed through grooves of a certain width, then, in a second pax, through grooves of a somewhat smaller width, and finally in a third pass through grooves of still smaller Width.
  • the rolls of one set are at right angles to those of the other set, in a skew relation thereto, since their axes do not intersect.
  • the grooves a of the vertical rolls 2 are at the same distance from the inclined plane in which the slide 3 moves, as the grooves (Z of the horizontal rolls 1; this is indicated clear- 1y by the arrow extending from a to d, which arrow is parallel to the path of said slide 3.
  • the grooves c of the vertical rolls 2 are at the same distance from the inclined plane above referred to, as the grooves f of the horizontal rolls 1.
  • the grooves b of the vertical rolls 2 are at the same distance from the above-mentioned inclined plane, as the grooves e of the horizontal rolls 1.
  • a rolling mill comprising two sets of rolls, each roll having a plurality of operating portions at different distances from one of its ends, the rolls of one set being parallel to each other but at right angles and in skew relation to those of the other set, stationary bearings for the rolls of one set, a slide in which the rolls of the other set are journaled, a guide on which said slide is movable in a direction oblique to the axes of the rolls of both sets, and means for moving said slide.
