Definitions

  • the present invention relates to a device for driving a laminated metal strip.
  • This device is intended to be mounted next to a tape winder in a broadband rolling mill.
  • tape drive devices in which the tape passes between two parallel drive rollers, mounted in a cage.
  • the lower roller whose diameter and weight are smaller than those of the upper roller is fixedly mounted in the cage.
  • the upper roller is mounted at its ends in bearings which are guided vertically in the cage.
  • the upper roller can be lifted during the engagement of the strip so as to allow the passage of this strip downstream.
  • the downward movement of the upper roller is limited by fixed stops against which the bearings can be applied.
  • the application of the bearings of the upper roller is carried out with great force by preloaded springs.
  • the air gap between the rollers which is adjusted using the fixed stops is slightly less than the thickness of the laminated strip. This air gap is adjustable as a function of the thickness of the laminated strip by adjusting the vertical position of the fixed stops.
  • the force exerted on the strip is equal to the sum of the weight of the upper roller and the force of the preloaded springs which apply to the bearings of this roller.
  • This force exerted on the strip is substantially constant and low, which does not correspond to the best conditions for achieving good training and good guidance of the laminated strip.
  • the invention aims to overcome the drawbacks of existing tape drive devices.
  • the device according to the invention maintains the lower roller in a fixed position for waiting for the engagement of the hot strip. It absorbs the impact of band engagement. It allows, after engagement of the strip between the drive rollers, to adjust the pressure force on this strip, this adjustment can be obtained separately on each bearing mounted at the end of the lower roller. It makes it possible to use a constant and preset hydraulic pressure, when the rollers are in the standby position of the strip or when this strip is engaged between these rollers.
  • the bearings of the upper roller can be positioned against a fixed stop using a prestressing force greater than the separation force of the driving rollers. The position of the fixed stop is preset according to the thickness of the laminated strip.
  • the belt drive device comprises a frame which guides bearings mounted at the ends of two driving rollers so that the axes of these rollers move relatively in a vertical plane, the upper roller being moved by means motors, and it is essentially characterized by the fact that the bearings of the upper roller are applied by said motor means against fixed stops and by the fact that it comprises jacks whose pistons support the bearings of the lower roller and are moved vertically by pressurizing chambers located on the bottom side, each of these jacks being equipped with means capable of moving the end of travel of said piston upwards.
  • the means capable of moving the end of stroke upwards of the piston comprise a ring housed, on the rod side, in the cylinder so as to limit the stroke of the piston upwards and to form a chamber.
  • upper annular connected to a hydraulic fluid supply line, this ring being capable of being applied in the low position against a stop defining a low end of stroke limiting the stroke of the piston upwards.
  • Figure 1 shows schematically in side view and in section, the tape drive device according to the invention.
  • Figure 2 shows the hydraulic circuit of a cylinder for moving the lower roller of the device.
  • the device shown in Figure 1 is used to drive a metal strip 2 which has just been laminated and which will be wound up. It comprises two lateral frames 3 which are arranged on either side of the metal strip 2. The latter passes between two driving rollers 4 and 5 whose axes 41 and 51 are horizontal. Bearings 42 and 52 are mounted respectively at the ends of the rollers 4 and 5. These bearings 42 and 52 are guided respectively by vertical slides 31 and 32 formed by lights of the side frames 3. Thus the rollers 4 and 5 can move relatively in a vertical plane. These drive rollers 4 and 5 are rotated around the axes 41 and 51 respectively, using drive means which are not shown in the drawings.
  • the upper roller 5 can be moved vertically using motor means.
  • These drive means are constituted by double-acting hydraulic cylinders which are each associated with a bearing 52 of the upper roller.
  • Each of these jacks comprises a cylinder 61 which is fixed to the frame 3 and a piston 62 which is integral with a rod 63 hinged to an associated bearing 52.
  • the upper roller is in the high position when the winding device is not used and the strip is directed to a machine located downstream. It is in the low position during use of the winding device. In this low position, the bearings 52 of the upper roller are applied against stops 7 integral with the frame 3 and whose vertical position can be adjusted.
  • These adjustable stops can be of the wedge type or of the screw jack type or of any other equivalent type.
  • stops are adjusted by the operator so that the interval between the upper roller and the lower roller is slightly less than the thickness of the metal strip.
  • the bearings 52 of the upper roller are applied against the stops 7 with an application force which is greater than the maximum separation force generated between the two drive rollers so as to create a preload of the elements associated with each bearing.
  • Each frame 3 is equipped with a hydraulic cylinder which is identified as a whole by the reference 1.
  • Each of these cylinders comprises a cylinder 11 resting on the frame 3 and a piston 12 which is integral with a rod 13 on which rests a bearing 42 of the lower roller.
  • the piston delimits, on the side of its lower face and the bottom of the cylinder, a lower chamber 14 which is supplied by a conduit 15. The pressurization of this chamber 14 moves the piston 12 vertically upwards.
  • each cylinder is equipped with means capable of moving the end of travel of the piston up.
  • each cylinder comprises a ring 16 which is housed on the rod side in the cylinder so as to limit the stroke of the piston 12 upwards.
  • Each ring 16 can slide with seal on the rod 13 which itself crosses the cylinder 11 with seal.
  • this ring 16 can slide with seal in the bore of the cylinder 11 so as to form a sealed annular chamber 17 on the side of its upper side.
  • This annular chamber 17 which surrounds the rod 13 is connected to a hydraulic fluid supply line 18.
  • the ring 16 can be applied in the low position against a stop which defines a low end limit limiting the stroke of the piston towards the top. This stop is constituted by the bottom of the cylinder 11.
  • the ring 16 has a bell shape which allows it to abut against the bottom of the cylinder 11 when the chamber 17 is pressurized. Due to the bell shape of the ring 16, the diameter of the piston 12 is less than the diameter of the inner bore of the cylinder 11. The piston 12 is free to move inside the ring 16 including the upper flange can be applied against the shoulder formed by the piston and its rod.
  • the diameter of the lower chamber 14 is preferably less than the diameter of the piston 12.
  • the annular surface of the ring, on the side of the annular chamber 17, is greater than the surface for applying pressure in the chamber 14 located above below the underside of the piston, i.e. on the surface of a horizontal section. Therefore, when the chambers 17 and 14 are supplied under equal pressures, the ring 16 is applied against the lower bottom of the cylinder 11.
  • the hydraulic circuit represented by FIG. 2 comprises an electro-hydraulic distributor 20 which controls the supply of hydraulic liquid to the upper chamber 17 from the supply line 23.
  • a pressure regulator 21 the control of which is available to the the operator modifies the pressure of the hydraulic fluid between the supply line 23 located upstream and the line 15 opening into the lower chamber 14.
  • a hydraulic damper 19 is connected to the line 15 located downstream of the pressure regulator 21.
  • the lower roller 4 Before the engagement of the metal strip between the rollers, the lower roller 4 is in the low and fixed position. This position is lowered by putting the chambers 14 and 17 under pressure. Because the pressures in these chambers are equal and the surface of ap plication in the chamber 17 is greater than the surface of application in the chamber 14, the ring 16 is in abutment against the lower bottom of the cylinder 11. The piston 12 is applied against the collar of the ring 16. The position of the roller upper 5 is adjusted by the stops 7.
  • the bearings 52 of the upper roller remain applied against the stops 7.
  • the bearings 42 of the lower roller can then move slightly downwards by pushing the piston 12 and pushing back and or by compressing the liquid in the chamber 14.
  • the mobile assembly formed by the lower roller and by its bearings is lighter than the mobile assembly formed by the upper roller and its bearings. As a result, the harmful effects due to the shocks caused by the introduction of the strip are relatively reduced.
  • the pressure in the annular chamber 17 is removed using the distributor 20. Therefore the ring 16 is free to move inside the cylinder 17 and it can therefore go up to come up against the upper bottom - rod side - of the cylinder.
  • the stroke of the piston 12 is therefore increased by the stroke of the ring 16.
  • the pressurization of the upper chamber 17 corresponds to a low end of stroke limiting the stroke of the piston upwards.
  • the removal of the pressurization of the upper chamber 17 corresponds to a high end limit limiting the stroke of the piston upwards.
  • the lower roller 4 is applied to the metal strip with a force corresponding to the pressure prevailing in the chamber 14.
  • This pressure is constant but it is adjustable by the operator as a function of the dimensional characteristics of the strip 2.
  • This setting of the pressure in chamber'14 can be obtained using the pressure regulator 21.
  • the pressure can be adjusted differently between the cylinders located on the right and left side of the strip so as to compensate for any symmetry defects in the drive device or in guiding the strip.
  • the annular chamber 17 is again pressurized by maneuvering the distributor 20 so as to position the lower roller in its fixed waiting position.
