Definitions

  • the present invention relates to an improved routing installation such as a roller transport bench, in particular for metal strips, intended to prevent longitudinal deformation of the head of said strips during transport.
  • a metal strip is conveyed to a winder by a roller transport bench over a distance which can be of the order of a hundred meters.
  • the strip which leaves the rolling mill at a relatively high temperature and at a speed of the order of ten meters per second tends to undergo longitudinal deformation at the level of its head, which, under the effect of the resistance of the air rises during its movement so that it no longer applies to the pass line, formed by the plane tangentially to the rollers of the transport bench.
  • the invention aims to remedy this drawback by providing a routing installation requiring only a simple transformation of a conventional transport bench and making it possible to effectively maintain the heads of the bands in the vicinity of the pass leg.
  • Document DE-A-2 417 037 discloses a cold rolling installation in which, immediately upstream of the rolling stand, are rolls intended to form longitudinal ribs along the edges of the sheet.
  • this patent concerns a different field of application and also aims to solve a problem different from that set out above. above. Indeed, it is sought in the previous arrangement to prevent a transverse curvature of the sheet, a longitudinal curvature obviously cannot occur given the presence of guides 6, 7 immediately upstream of the rolling rolls.
  • the cylinders making the ribbing on the edge are not driven, which would also make them unsuitable for use in the precise context targeted by the invention.
  • the invention therefore relates to an installation for routing metal strips, between an upstream station such as the outlet of a hot rolling train and a downstream station such as a winding station, located at a distance from the upstream station , characterized in that it comprises a retractable ribbing device for the head or front end of the strip, disposed in the vicinity of the upstream station, the ribs formed on the head of the strip being oriented parallel to the longitudinal direction of the latter, the ribbing device comprising two rolls of approximately complementary profiles, arranged horizontally on either side of a pass line, driven in rotation and capable of being moved away from said pass line.
  • the bending of the head of the strip thus makes it possible to modify its resistance to bending notably and then provides it with very good longitudinal rigidity which is opposed to any deformation tending to lift it.
  • the device shown in the figures is incorporated according to the invention in a roller transport bench, comprising a frame 1 in which are rolled rollers 2, driven by motors 3. This part of the installation will not be described in detail .
  • the roller bench is arranged, for example, between the last finishing stand of a strip rolling train and a winding station, the distance between the stand and the winding machine possibly being of the order of a hundred meters.
  • the installation comprises a device for ribbing the head of the strips, which will be described below, arranged at a short distance, of the order of a few meters, downstream of said finishing cage. In Fig. 1, the strip moves from left to right.
  • the frame 1 is completed by uprights 4, 5 (Fig. 4) arranged on either side of the bench, each having at their upper part a bearing 6.
  • the bearings 6 aligned and each equipped with an anti-friction ring 7 (Fig. 4 1 support for rotation about an axis XX a shaft 8, integral with a support and displacement mechanism for an upper ribbing roller 9, able to cooperate with a lower ribbing roller 10.
  • the roller 10 is movable vertically by means of a support and displacement mechanism, oscillating around an axis YY parallel to the axis XX. of rib 9, 10 are kinematically connected to each other by an arm 11 cooperating with a connecting rod 12.
  • a cross-bevel in the direction of the rolling mill is provided on the frame 1 arranged horizontally at the pass line, in the upstream vicinity of the roller lower 10, in order to guide the front of the strip between the rollers 9, 10.
  • the entire device is actuated by means of a jack 13, articulated on the frame 1, the piston rod 14 of which is articulated on one end of an arm 15, integral in rotation at its opposite end, with an extension 16 of the shaft 8 (Fig. 4) which extends beyond the bearing 6 (Fig. 1).
  • the support and displacement mechanism of the upper ribbing roller 9 comprises two arms 17 integral with the shaft 8, fixed parallel to each other at each end of said shaft, between the uprights 4, 5.
  • the arms 17 support at their free end the ribbing roller 9, rotatably mounted by pins 18.
  • the ribbing roller 9 cooperates with the lower ribbing roller 10 (Fig. 3), these two rollers being profiled along their length with a roughly complementary relief, of general shape sinusoidal with an amplitude which can be different for each of them. They are also each driven by a motor such as 3 a (Fig. 3).
  • the mechanism for supporting and moving the lower ribbing roller 10 comprises two parallel arms 19 (FIG. 2) mounted to oscillate around pins 20 provided on either side of the frame 1.
  • the ends of the arms 19, opposite the pins 20, are connected by a cross member 21 (FIG. 2) carrying two flanges 22 between which the rib roller 10 journals.
  • On a lower extension 23 of each flange 22 (FIG. 1) is articulated around an axis 32 a flange 24 a forming with a flange 24 b a circular orifice 25, equipped with an anti-friction ring 26 (Fig. 3), each orifice 25 serving as a rotation track for an eccentric 27.
  • a shaft 28, transverse to the frame 1 and supported in rotation by two bearings 29 provided in a lower part of said frame is integral in rotation with the eccentrics 27.
  • the latter fixed perpendicular to the axis of the shaft 28, is articulated on the connecting rod 12.
  • the end of the connecting rod 12, opposite the crank 30, is inserted between the two elements 11a, 11b (Fig. 4) of the arm 11 and is articulated around 'an axis 31 located behind a widening 11 c , provided at about two thirds of the length of the arm 11 from its upper end, the latter being integral in rotation with the shaft 8, at its extension 16 .
  • the device is equipped with adjustment means comprising on the one hand, a member for adjusting the spacing of the rollers in close position which comprises an adjustable stop 33 carried by the frame, intended to cooperate with a complementary stop 34 formed to the lower part of the arm 11.
  • Said adjustment means comprise, on the one hand, a member for adjusting the position of the lower ribbing roller 10 relative to that of the upper roller 9, comprising a screw jack that of the upper roller 9, comprising a screw jack 37 incorporated in the connecting rod 12 and making it possible to modify the length thereof.
  • a modification of the length of connecting rod consequently modifies the angular position of the eccentrics 27 and consequently the position in height of the lower roller 10.
  • means for interrupting the ribbing are arranged downstream of the device.
  • These means may include a sensor placed at a certain distance from the rollers 9, 10, which corresponds to the desired ribbing length.
  • the sensor can be mechanical, electrical, electromagnetic, photoelectric or of another known type, or even replaced by a time-delay device which controls the supply circuit of the actuator 13 in a known manner.
  • the operation of the device described above is as follows: after having made the adequate adjustment of the stop 33 and of the screw jack 37 as a function of the thickness of the strip to be ribbed, the ribbing rollers 9, 10 are brought together and driven in rotation with a speed synchronized with that of the belt.
  • the head of the metal strip coming from the finishing stand of the rolling train, at a temperature between 830 and 900 ° C, progresses on the dynamometer and passes between the rollers 9, 10 where are formed parallel ribs of an amplitude and a determined length, oriented lengthwise, until the front of the strip reaches the level of the sensor which interrupts the ribbing by controlling the jack 13.
  • the jack 13 pulls the arm 15, integral in rotation with the arms 17 and the arm 11 via the transverse shaft 8, which has the effect, on the one hand, of lifting the upper roller 9 and, on the other hand, to do turn (clockwise) the arm 11 which pushes the connecting rod 12.
  • the connecting rod 12 pushes down the crank 30, thus forcing the eccentrics 27 to turn via the shaft 28, integral of the crank 30 and on which the eccentrics 27 are rotated.
  • the rotation of the eccentrics 27 causes the lowering of the flanges 24a and therefore of the lower roller 10 by oscillation of the arms 19 around the axis Y-Y.
  • the shape thus given to the heads of the strips makes it possible, by stiffening them longitudinally, to effectively maintain them in the vicinity of the pass line to facilitate their introduction into the winders.
  • This advantage is further accentuated by the fact that the ribs allow the water, coming from a cooler located downstream of the device according to the invention, to temporarily park on the surface of the strip, which has the effect of significantly increase the mechanical properties thereof.
  • the two ribbing rollers 9, 10 can each be carried at their ends by chocks slidably mounted in vertical slides, arranged on each side of the frame 1.
  • the spacing of chocks and therefore rollers is controlled by any suitable means, for example, hydraulic cylinders or cam or eccentric mechanisms.
