Definitions

  • the present invention relates to a device for unwinding filiform products, in particular filled wires, wound in the form of crowns, arranged on baskets or not and intended for the introduction of additives into molten metal baths.
  • cored wires consist of a tubular metallic sheath filled with a powdered core constituting the additive itself.
  • the additive can be pulverulent or granular and consist, for example, of Al, Ca, Ni, Ti or alloys such as SiCa, SiCaBa and SiZr.
  • the use of such a cored wire makes it possible to double the effect of a deoxidation / desulfurization of an alloy effect.
  • the metal sheath is usually formed by a thin strip of mild steel closed by stapling. The thickness of the strip is about 0.4 mm for cored wires having a diameter of 13 or 18 mm, while it is only 0.2 mm for cored wires having a diameter of 5.7 or 9 mm.
  • Baskets are usually used to transport and store the cored wires. These have sufficient stability to guarantee adequate protection of the wires wound on them. They also ensure the order and storage of the turns during the winding and unwinding operations. Baskets are usually made of wood, sheet metal or wire and carry a useful weight of one ton for large diameter cored wire (13 or 18 mm) or 150 kg for small diameter cored wire (5, 7 or 9 mm).
  • the user places the coil on a mobile metal reel fitted with a braking device; braking not only makes the more regular rotation of the spool, but it also prevents the spool from continuing, under its inertia, to unwind when the operation of introducing wire into the metal bath is stopped. Note that in order to save time, both starting and stopping this operation is quite brutal.
  • the useful quantity of material stored on spools of 150 kg of thin cored wire is sufficient to process one to two metal charges.
  • To decrease the rate of replacement of the reels it is necessary to wind the wire on larger baskets, so as to obtain reels of a minimum ton.
  • the tubular metal sheath which has a thickness of 0.2 mm, is subjected, during starting or stopping braking, to stresses which exceed its resistance to rupture.
  • the object of the present invention is to remedy the defects described above and to propose a simple, robust device which can be quickly put in place and which makes it possible to unroll filiform products having low resistance to breakage without any problem.
  • the device according to the invention which is characterized in that it has a smooth surface opposite each point of the crown, in that the smooth surface is arranged in the volume delimited by the two defined planes by the upper and lower sides of the crown and in that the device comprises means for maintaining the smooth surface near one of the sides of the crown.
  • the advantages of the invention essentially consist in that the device can be manufactured in a simple manner, that it is easy to set up, that it can be used with coils of different diameter and that it has a long service life.
  • FIG. 1 there is a coil 10 laid flat and having a lower cheek 11, as well as an upper cheek 12.
  • the device 14 for unwinding the cored wire 1 essentially comprises an O-ring 16 fixed by three vertical arms 19 to a second ring 15 having substantially the same diameter.
  • This ring 15 is connected by means of three horizontal arms 17 to a central part 13 in the form of a disc.
  • an appropriate means in the present case elastic tabs 21 which penetrate into the core of the coil
  • the surface presented by the ring 16 to the wire being extremely smooth and the ring being able to rotate around its axis, the cored wire must not overcome only a slight frictional force and is not subjected to any transverse force coming from the device 14, this regardless of the position of the turn being unrolled. Note that this device is particularly advantageous for unwinding cored wire small diameter.
  • Figure 2 shows an alternative embodiment of a device according to the invention, which has substantially the shape of an inverted plate.
  • the profile of the rim 26 is extremely smooth and has a shape adapted to limit the friction of the cored wire, regardless of the position of the turn being unrolled.
  • This device preferably made of metal, is quick to set up, since it remains in position under the effect of its own weight.
  • FIG. 3 there is a flexible profiled strip 34 with a smooth rim 36, fixed by dry friction on the upper cheek 12 of the coil 10.
  • the ends of the ribbon are superimposed over a length which depends on the diameter of the cheek 13. 'At each turn , passing the end of the ribbon, the cored wire falls against the latter. Compared to the diameter of the cheek, this discontinuity in the wire guide device is low.
  • the profiled tape which has a substantially U-shaped section, is made of plastic resistant to high temperatures. Given the proximity of the container metallurgical and the risks of projection of molten material, it is preferable to provide a protective screen between the coil and the container.
  • Figure 4 shows an example of filling a basket 43, arranged on a rotating base 44 which performs, next to its rotational movement also in vertical oscillatory movement (trancanning).
  • the cored wire 1 is brought into the basket by means of a fixed system of feed rollers 41 and dressing 42.
  • Figure 5 shows a mode of winding cored wire 1 from the inside of a coil.
  • the basket 53 which is placed on a pallet 54, has two inner rings 56 having an extremely smooth surface so that the cored wire 1 does not have to overcome, whatever the position of the coil in the crown, that a very weak friction force out of the basket.
  • FIG. 6 shows a crown without support 60, placed simply on a pallet 64.
  • Three arms in the form of a gallows, support a ring 66.
  • the arms 61 can be fixed on the pallet 64 or remain in place under the effect the weight of the device.
  • two bars 76 can also be used, fixed to four pillars 71 which are themselves integral with the pallet 74 (see FIG. 7). 'When the bars 76 and the pillars 71 are mounted on the pallet 74 at the flux-cored wire factory, they can help keep the crown 70 in place on the pallet 74.
  • Figure 8 shows a section along lines VIII-VIII through the device shown in Figure 7. '
  • the ring 66 and the bars 76 play, besides their role of guiding the wire, also a role of holding the crown on the pallet at the end of unwinding.
  • FIG. 9 shows a preassembled star according to the invention, intended to be simply slid over a ring of wire.
  • This star is constituted by two smooth rings 96, to which have been welded (on the outer sides) three bars 93 in the shape of a U as well as six straight horizontal bars 98 which are located opposite two by two. As soon as the crown is inside the star, three vertical bars 99 are welded to the horizontal bars 98 which are located opposite. The free space between the two rings in this case determines the maximum height of the crown.
  • FIG. 10 also shows a basket mounted around the crown 100 after the manufacture of the latter. After the establishment of two rings 106, six U-shaped bars 103 are slipped around the crown 100 and they are fixed to the outer sides of the two rings 106.
  • the loosening / loosening effect of the wire remaining on the crown can also be obtained by other deformations of the ring, for example by providing it with several undulations.
