Definitions

  • the present invention relates to a method and a device for forming a coil of metal wire, in particular steel, according to the preambles of claims 1 and 7.
  • Devices of this type are notably used in installations for rolling metal wires to form coils which are then compacted and tied.
  • the wire is preformed into turns which are then arranged substantially flat and overlapping one on the other on a generally provided cooling conveyor, during the displacement of which the wire turns are cooled.
  • the wire turns fall one after the other in a well with a cylindrical wall and a vertical axis, with a diameter slightly greater than that of the turns, where they stack to form a coil which is then extracted from the well to be compacted and bound before storage or use.
  • the turns although partially guided by an axial warhead placed inside the well, tend to deposit on each other in a disorderly manner. It follows that the height of the coil thus formed is much greater than if the turns were well ordered.
  • the coils are then compacted, by exerting an axial pressure on them.
  • the turns being arranged in a disorderly manner, the wires cross in many places, and during compaction wire the risk of injury at these crossings is important.
  • Document GB-A-759575 discloses an installation for winding falling wire in a well in which the speed of feeding of the wire is controlled by that of rotation of the well so as to control the radial position of deposit at all points. of wire in the well and thus order the arrangement of the turns formed and therefore reduce the size of the winding.
  • this type of installation requires not only very precise regulation of the linked speeds involved, but also the rotation of the well itself, which is hardly compatible with large masses, in particular in the steel industry where the coils of wire typically weigh several tonnes.
  • the object of the present invention is to solve these problems and to propose a system for forming a coil which makes it possible to order the arrangement of the turns, to reduce the size of the coils and to avoid injuries to the wire.
  • the invention relates to a method of forming coils of wire of the type indicated at the beginning of this thesis, this method being characterized in that it is applied to metal wire which can be attracted by a magnet, and during the fall of the turns, a radial force of attraction is exerted on them towards the wall of the well, said force being generated by a rotating magnetic field which penetrates inside the well over a depth at least equal to the difference between the internal diameter of the well and the diameter of the turns, and the direction of this force being driven by a rotational movement around the axis of the well.
  • the invention also relates to a device for forming coils of metal wire previously shaped into turns, comprising a coil formation well having a cylindrical wall with a vertical axis, and a horizontal plate for supporting the coil in formation, characterized in that it includes inductors generating a rotating magnetic field to exert on said turns a radial force of attraction towards the wall of the well, rotated around the axis of the well.
  • the method and the device according to the invention make it possible to order the arrangement of the turns in the coil during formation, so that they are arranged in superimposed layers, the turns of each layer being angularly offset from each other.
  • each turn, or group of turns is substantially in contact with the wall of the well at a point and the respective contact points of two successive turns, or groups of turns, are regularly offset circumferentially.
  • the proliferation of turns is thus optimized during the formation of the coils. This results in a substantial gain, at constant wire length, on the height of the coils and therefore on the size thereof.
  • the turns being regularly arranged in the coils these hold better and are less likely to deform during handling. Since the coils thus formed are more compact, the subsequent compaction operations can be reduced, or even eliminated, which can lead to the elimination of the compactors and therefore to the reduction of the time and cost of manufacture, or at least to the reduction of the risk. wire injury during compaction.
  • the magnetic field is generated by inductors such as electromagnets regularly distributed around the periphery of the formation well and supplied cyclically with direct current.
  • the cyclic attraction of the metal turns towards the wall of the coil formation well can be carried out in a very simple manner without mechanical organs intervening inside the well.
  • the use of a magnetic field generated by electromagnets also makes it possible to easily adjust the intensity of the attraction force as well as the speed of rotation of the rotating field as a function of the diameter of the wire, the dimensions of the turns, and the speed of the conveyor for transporting the turns and also the speed of fall of the turns in the well.
  • electromagnets placed outside the well makes it possible to easily adapt the method according to the invention to existing installations, without significant modifications to the well, only the wall of the well at the height of the electromagnets having to be produced in a non-magnetic material.
  • Electromagnets 5, five in number in the example shown, are distributed circumferentially at the periphery of the intermediate ferrule 4 on which they are fixed.
  • the height of the electromagnets 5 is slightly less than that of the intermediate ferrule 4, so that substantially all of the lines of the magnetic field created by the electromagnets in operation pass through said intermediate ferrule.
  • a horizontal plate 6 movable vertically, its upper position being located at the level of the intermediate ferrule 4.
  • This plate is intended to support the coil 7, and is gradually lowered so that the upper part of the coil being formed remains permanently in the action zone of the field created by the electromagnets 5.
  • the device is shown at the start of training, the coil 7 then being formed only by a few turns of the wire 10 deposited on the plate 6 in the high position.
  • the plate 6 is annular and surrounds a central mandrel 8 which ends upwardly with a warhead 9 intended to ensure complementary guidance of the turns 10 of wire when they fall into the well 1 and in particular to prevent the turns falling obliquely and disrupt the formation of the coil.
  • the warhead 9 which is at the height of the intermediate shell 4 is preferably made of non-magnetic material. This warhead is however not essential, in particular during the winding of large diameter wire, because the implementation of the method according to the invention has the effect of guiding the fall of the turns and of ordering their positioning in the coil. .
  • the electromagnets 5 are arranged "horizontally", that is to say so that the general direction of the field lines which extend between the two poles of the same electromagnet is in a horizontal plane.
  • the electromagnets can be shaped according to the schematic representation of FIG. 3, the magnetic yoke of these having a U shape and the poles formed by the ends of the branches of the U extend vertically over a height slightly less than that of the non-magnetic ferrule 4 and are attached to the outer surface thereof.
  • the electromagnets 5 and their means for supplying electric current are determined so that the effect on the turns of the field which each electromagnet generates, is essentially located in the part of the annular zone comprised between the intermediate ferrule 4 and the warhead 9 and located opposite said electromagnet.
  • the internal diameter of the well is greater than that of the turns.
  • the diameter of the well is 1150 mm and that of the turns about 1050 mm.
  • Each turn therefore has a possible horizontal clearance inside the well of approximately 100 mm.
  • the turn or turns in the fall which are at the height of the intermediate ferrule 4 may therefore be distant from the wall of this ferrule situated opposite said electromagnet by about 100 mm, or even more to account for the fact that the turns can be tilted relative to the horizontal.
  • the penetration depth of the magnetic field into the well will have to be adapted in particular as a function of the diameters of the well and of the turns, and also as a function of the presence or absence of the warhead and of the diameter thereof. this.
  • the device includes means, not shown, for cyclically supplying the electromagnets 5 with direct current.
  • These means make it possible to power the electromagnets according to several different cycles.
  • the electromagnets are respectively identified by the letters a, b, c, d, e
  • the direction of rotation can also be reversed.
  • the plate 6 is brought into its upper position shown in FIG. 1, at the height of the intermediate shell 4.
  • the first turns 10 fall into the well 1 and fall on the plate 6. It is specified that in the case where the device is suitable for an installation of the type described in the document FR 2 105 309 cited above, and to which reference will be made for possible additional information, the first turns can be deposited on retractable fingers which penetrate into the well and ensure the support of the coil awaiting return to the high position of the plate, these fingers then disappearing to allow the coil during formation to come to rest on the plate.
  • the wire turns are attracted by the electromagnets 5 and, due to the cyclic supply of these which creates a rotation of the magnetic field, the turns are distributed circumferentially in partial overlap as shown in FIG. 2.
  • the descent of the plate 6 is controlled so that the upper part of the reel being formed remains at the level of the intermediate shell and thus remains subject to the action of the magnetic field.
  • the descent of the platform so to maintain the upper part of the coil near the bottom of the zone of influence of the electromagnets.
  • the field will have a predominant effect on the turns during the fall, the necessary attraction force of said turns then being relatively low.
  • the field will however still have an effect on the turns which have just deposited which will make it possible to avoid the possible displacement of them which could result for example from the elasticity of the turns.
  • the underlying turns being out of the field are not likely to move due to the pressure exerted on them by the upper turns.
  • the plate When all the turns are removed and the reel has been formed, the plate is lowered to the low position and the reel is discharged.
  • the height of the coil is significantly reduced compared to that of the coils produced according to the prior art, in which the turns were distributed without any regularity by randomly overlapping.
  • each electromagnet is supplied with direct current and operates at around 40,000 ampere-turns in the winding. Five electromagnets are used and successively supplied the created field rotating at a speed of about 0.25 revolutions per second.
  • the speed of rotation of the field can vary in large proportions, depending in particular on the power cycle of the electromagnets chosen, the characteristics dimensions of the wire and the speed of fall of the turns. It also depends on the ramp-up time of the electromagnets, which implies a minimum supply time for them so that the magnetic field created can produce a sufficient attraction effect on the turns.
  • the electromagnets are preferably placed so that the adjacent poles of two neighboring electromagnets have the same polarity.
  • the number of magnets can be modified and these can be arranged so that the adjacent poles of two adjacent electromagnets are of the same polarity, or of reverse polarity. It will be noted that in the case of adjacent poles of the same polarity, the number of magnets will preferably be even to avoid a discontinuity in the distribution of the poles.
  • the rotating magnetic field can also be generated by any means known to those skilled in the art in the field of electromagnetism using for example polyphase inductors or a cylinder head and windings similar to those of an electric motor stator, supplied with direct current or not.
  • the magnetic field may also be exerted over a greater or lesser height and at a level more or less close to the upper end of the well, the respective heights of the intermediate or upper ferrules being adapted accordingly.
