Definitions

  • This invention relates to an element for a rolling stand, and also the rolling stand obtained with this element, as set forth in the respective main claims.
  • the invention refers to a modular element to obtain a finishing stand or a post-finishing stand in a rolling line.
  • the invention also refers to a finishing or post-finishing stand obtained with one or more pairs of elements according to the invention.
  • the invention is applied in the field of hot rolling of thin products, having rounded, squared, hexagonal, rectangular, or other transversal section, of a nominal diameter or transversal dimension between 4 and 16 mm,, made of steel and particularly during the finishing and post-finishing steps which precede the arrival of the product on the coil-forming head or before the cooling bed or cooling belt.
  • the state of the art covers post-finishing stands with two or four rolling passes to obtain the desired finish to the hot rolled products having a thin section normally of between 4 and 16 mm.
  • Document JP-A-57-190703 describes a rolling stand constituted by two groups, each having a rolling roll cantilevered mounted on a corresponding support flange rigidly fixed to a driving box on which a driving motor is mounted.
  • each rolling roll is offset with respect to the axis of the motor, for varying the distance between the rolling rolls, one entire group, is moved with respect to the other, including the driving box and the motor,
  • Document DE-A-29 15 295 describes a rolling stand with cantilevered mounted rolling rolls for the production of wire rods, wherein a single motor causes the rotation of three groups of rolling rolls disposed at 120° one with respect to the others.
  • each group of rolling rolls is swinging with respect to the driving axis by means of complex and expensive actuating hydraulic cylinders.
  • Document GB-A-502,456 describes a very old system for regulating the distance between the rolling rolls of a rolling stand, constituted by two autonomous groups, wherein each group is slidably mounted on a fixed frame and wherein the rolling rolls are cantilevered mounted and offset with respect to the driving means. Also in this system, for varying the distance between the rolling rolls, the two groups are reciprocally moved with respect to the fixed frame, whereby the system itself is cumbersome and unsuitable, and does not solve the problem of the reduced center distance between the rolling rolls.
  • a modular element which bears rolling rolls or rings with a minimum diameter of about 70 mm and a maximum diameter of about 140 mm.
  • the axis bearing the rolling roll/ring is borne offset by a disc or ring type flange which can rotate around its own axis and allows the roll/ring-bearing shaft, which is parallel to the axis of rotation of the flange, to rotate describing at least a arc of a circumference.
  • the roll/ring-bearing shaft is supplied with motion by a gear which is coaxial to the axis of rotation of the flange.
  • the gear which carries the motion coaxial to the flange receives motion directly from a kinematic motion common to all the elements of the stand.
  • each element receives motion from its own drive device.
  • the gear which carries the motion coaxial to the flange receives motion from a pair of tapered gears which is made to rotate by a common kinematic motion.
  • two rolling rings or rolls can be made to cooperate so as to constitute a finishing stand or pass, with the respective support boxes or shaft-bearing elements on which the flanges are positioned, without there being any interference between the boxes themselves; the boxes are thus facing each other, offset and inverted with the axes of the rolling rolls or rings offset but parallel therebetween.
  • the source of motion for example, including a vertical plate with the desired kinematic chain or reduction unit inside, may include on one face two outlets which are connected to two elements according to the invention so as to constitute a first finishing pass.
  • the source of motion may include two plus two outlets so that four elements according to the invention (two plus two) may be installed so as to constitute two successive finishing passes.
  • the elements according to the present invention include means to position them rapidly on the motion means.
  • the element in a side view, is shaped like a "P", with the rolling roll or ring mounted on the lower terminal end of the leg of the "P".
  • each modular element 10 includes a support box 14 to which is associated a disc type flange 13 which is provided of a pivot 29 which allows the flange 13 to rotate around a first rotational axis 16.
  • the support box 14 is able to be removably fixed, for example to a frame 30, in a predetermined position with respect to a rolling axis 11.
  • a driving shaft 24 coaxial to the first rotational axis 16 and provided with a driving gear 124 of cylindrical form.
  • a driven shaft 25 is rotatably mounted on the flange 13, coaxial to a second axis of rotation 18, which is parallel and offset with respect to the first rotational axis 16.
  • a rolling roll or ring 12 At an external end of the driven shaft 25 is cantilever mounted a rolling roll or ring 12 having a diameter between 70 and 140 mm., advantageously between 90 and 110 mm.
  • the driven or roll-bearing shaft 25 is provided on an internal end with a driven gear 125 meshed with the driving gear 124,
  • the driving shaft 24 is directly associated to an autonomous drive motor 15, so that in the case of a rolling stand with four rolling elements 10, which constitute two pairs of rolling rolls or rings 12, or two rolling passes, four drive motors 15 are provided (fig.1).
  • the driving shaft 24 is provided with a first tapered gear 23, meshed with a second tapered gear 123, which receives motion from a motion-inlet axis 17 which is parallel to the rolling axis 11.
  • the modular element 10 may be associated with a reduction unit 19 which contains any kind of kinematic chain whatsoever, which is associated with a drive device 26.
  • the reduction unit 19 comprises a central gear 20, coaxial to the rolling axis 11, able to supply motion to a driven gear 21 which, by means of a fast coupling 22, can be easily connected to the tapered gear 123.
  • the axis of the driven gear 21 coincides with the axis 17 whereby motion enters the element 10.
  • the center distance "i" between the rotational axes 18 of two adjacent pairs of rolling rolls or rings 12 is therefore very small, for instance between 130 and 450 mm., advantageously between 140 and 250 mm.
  • Fig. 2 shows an embodiment with three rolling passes.
  • Fast centring means and fast assembly/detachment means may easily be provided to removably fixing each element 10 to the frame 30.
  • successive rolling passes can be rotated by 90°, or an intermediate pass may be not rotated.
