Definitions

  • My invention relates to improvementsin rolling mills, and more partlcularly in mills comprising one set or a plurality of sets of rolls located in the direction of the movement of the blank one behind the other. Rolling mills of this type are used for example for reducing pipes.A
  • the object of the improvements is to provide a mill of'this type whlch is simple in construction, and in which the D operative parts are readily accessible. With' this object in view my invention consists in providing a both sets of rolls, which driving member 1s located between the'said sets and is connected i with the rolls by suitable intermediate drlvingmembers.
  • Fig. 1 is a sectional elevation showing a rolling mill comprising two sets of rolls and a.
  • Fig. 2 is an elevation looking from' the left in Fig. 1.
  • the i rolling mill comprises a frame t having two 'sets of rolls a and b mounted therein on shaftsr a1 and b1.
  • each set comprises four rolls and shafts, and the rolls and shafts of the setsgare displacedfwith relation to each other at angles of
  • the frame t comprises a median substantially cylindrical portlon t1 on which a cylindrical driving member c is rotatably mounted.
  • a spur gearing g is fixed which is in driving engagement with a gear wheel 8 keyed to a main 4driving shaft 1'.
  • hyperbolic gear wheels or the like (l ande are secured which are in mesh with pinions f1 and f2 keyed to the shafts@1 and b1 respectively.
  • the shafts a1 and b1 and pinions f1 and fzare not disposed with their axes in radial planes including the axis of the blankbeing rolled, Ybut they are spaced from the said planes and ommon driving member for and the gear wheels d, f1 and e, f2.
  • Fig. 2 also shows the relative position of the pinions f1 and f2, the pinions f2 and rolls connected .therewith belng shown in dotted lines.
  • the cylindrical portion t1 of' the frame includes a bearing for a guide h, A similar guide z' is provided at the right hand part of the frame. At the ends the fram-e t is closed by heads 7c and m. After removing the said heads the rolls are readily accessible.
  • a set of work-shaping rolls grouped to form apass for the work and comprising a plurality of airs of rolls with the center of the pass o the rolls in each pair rotating in a common plane intersecting the axis of the work at an angle with respect to the plane of rotation of the other rolls, each roll having an axis positioned out l of radialrelation to the work pass and provided with a gear, and a common driving gear meshed wit-h the gears on the roll axes and rotatably mounted in concentric relation to the work pass.
