Definitions

  • Leveling consists in deforming the strip so as to create an elongation of the shortest fibers until they reach the length of the longest ones. To be certain that no residual stress remains within the strip, the entire thickness of the sheet must be subjected to plastic deformation. This plastic deformation is ensured by the combination of traction on the strip and alternating bending.
  • the present invention intends to propose a leveling device which makes it possible to satisfy this new demand.
  • a device for leveling a metal strip under tension comprising at least two working rolls of small diameter between which the strip passes undergoing successive bending and in opposite directions.
  • this device comprises a third working roller, located downstream, in the direction of passage of the strip, relative to the first two rollers and whose position is adjustable relative to these first two rollers, to constitute a means of adjusting the angle of winding of the strip on the second roll, and to generate a third bending of the strip in the opposite direction to that which it undergoes on the second roll, the amplitude is a function of the relative position of said third roller relative to the second.
  • said third roller is rotatably mounted on a support pivoting about the axis of the first working roller relative to the frame carrying the aforementioned second roller.
  • each of the working rollers is carried by a pair of support rollers
  • the first and third above-mentioned working rollers are carried by three support rollers, one of which is common to the two working rollers, which are rotatably mounted on said pivoting support.
  • the device generally comprises a frame constituted by two vertical uprights wedges spaced from each other between which is articulated, around an axis coincident with that of the first working roller, a table, constituting the aforesaid support of the three support rollers of the first and third working rollers, a cylinder articulated between the end of the table opposite its articulation on the frame and the base of this frame, an upper plate overhanging the above table and carrying in rotation the support rollers of said second working roller, this plate being coupled to said amounts, and maneuvering means of the aforesaid jack to adjust and fix the inclination of the table around its articulation on the frame.
  • This jack is preferably a screw jack whose threaded rod is coupled to said table while the nut, immobilized in translation, is shaped like a wheel of a wheel and worm system whose screw constitutes the operating means. above.
  • the above-mentioned upper plate is carried by the end of a pivoting arm between said uprights from a first working position in which the plate is near said table, to a second position in which the plate is away from said table, said arm being in each of said positions, locked on the frame.
  • a jack coupled between the arm and the frame, allows the latter to be maneuvered between these two positions.
  • the diameter of the above-mentioned first working roller is less than the diameter of the second and third rollers.
  • each of these support rollers is constituted by an axial succession of rollers between which the abovementioned bearings are inserted. This arrangement makes it possible to withstand the significant forces to which the rollers 2 and 4 are subjected without deformation. It will be noted that the working rollers 2 and 4 are held axially with respect to the frame, by means of notches 12 and 13 formed in the sides of this frame and in which the axes of the rollers 2 and 4 are journalled.
  • the working roller 3 cooperates with support rollers 14 and 15 rotatably mounted in bearings 16 and 17 of an upper portion of the frame 18.
  • a retaining member 19 is provided which partially closes the notches 20 of the sides of the frame 18 in which the end axes of the roller 3 rotate.
  • the frame portion 8 is articulated relative to the portion of frame 18, as will be explained with reference to FIG. 2, around the axis of the above-mentioned roller 2.
  • FIG. 2 shows, in a schematic profile view, that the above-mentioned lower frame portion 8 is articulated around the geometric axis of the roller 2, by means of two bearings such as 21, which frame it and which are them -same attached to a support structure 22 belonging to the general frame of the machine not shown.
  • this support structure 22 is in the general form of two vertical columns forming two lateral frame uprights to which the constituent elements of the device according to the invention are coupled and between which the strip 1 can pass.
  • the frame portion 8 which supports the rollers 2, 4, 5, 6 and 7 is further coupled to a jack 23, around an articulation axis 8a, the other end of the jack 23 being articulated around 'an axis 24a on a lower frame part 24.
  • the jack 23 is here represented as a screw jack whose threaded rod 23a is articulated around the above-mentioned axis 8a, and whose nut 23b is immobilized in translation in a support 25 itself articulated in 24a on the part lower frame 24.
  • the above-mentioned nut 23b is formed into a wheel of a wheel and worm system, the screw 26 of which can be rotated about its axis, by means of a drive device not shown. It can be seen in this figure that the actuation of the jack 23 causes the pivoting of the frame part 8 about its articulation axis on the bearing 21.
  • the upper frame part 18, carrying the rollers 3, 14 and 15 is, for its part, articulated on the frame uprights 22 of a hinge pin 27, and can be raised and lowered around this axis by means a control cylinder 28.
  • Two bearings, such as 29, integral with the uprights 22 of the frame, can receive retractable locking elements in a direction perpendicular to the plane of FIG. 2, carried by the frame part 18.
  • two bearings symbolized by the bore 30 provided in the frame 22 can also receive this same locking device.
  • the frame portion 18 can be moved by the jack 28, between a first position in which it is locked on the bearing 29, which corresponds to the working position, and a second position in which it is locked in the bore. 30, which corresponds to a retracting position.
  • This mounting of the frame part 18 is advantageous because it allows free access to the working and support cylinder of the bottom frame part 8 and allows the machine to pass accidental excess thicknesses of the strip such as the welds. splicing.
  • the invention extends also to a device comprising means for fine adjustment of the relative positions of the rollers 2 and 3.
  • This adjustment can for example be carried out by a device allowing a modification of the coupling point at the frame portion 18 of the locking pins cooperating with the bearings 29.
  • the invention finds an interesting application in the field of the metallurgical industry.
