Definitions
- the present invention relates to a method according to the preamble of claim 1 (see eg US-A-5,669,420) and a device for manufacturing a cylindrical metallic structure called carcass and constituted by several metallic wires stapled to each other.
- This type of carcass can be used in particular in multilayer structures of reinforced flexible pipes to withstand the stresses due to internal or external pressures or to longitudinal forces.
- a spiraling of the strip is carried out, that is to say its low pitch helical winding with interlocking, followed by a final deformation to ensure locking of the stapling. It is notable that, taking into account the manufacturing method, the thickness of the strip cannot provide the final product with very high transverse inertia, which limits the resistance to crushing of carcasses according to the prior art.
- the present invention makes it possible to manufacture a larger carcass crush resistance using wires with a larger cross-section inertia.
- metal wires of cross section are used specific to provide lateral stapling of the wires together, i.e. a limitation of the play between the turns in the direction of the longitudinal axis of the flexible driving.
- it is not a question of auto wires staplable, that is to say having a section of unique shape and arrangement, generally in S or Z, which allows each turn to hold onto the previous thanks to its complementary profiles.
- the staples (not self-stapling) in U can be described as having a substantially rectangular section comprising both ends of one side of the rectangle, generally the longest, convex ribs, or bosses, thus forming the vertical bars of the U.
- the winding forms spring is locked longitudinally by another U-shaped wire whose bosses are turned towards the bosses of the first wire and placed in the recesses U. There is thus no radial locking but only a locking longitudinal, with respect to the axis of the pipes with an allowable play function width and space between the bosses.
- Wire staples (not self-stapling) in T can be described as a wire U-shaped comprising in the central part between the lateral bosses a reinforcement convex (foot of the T) substantially perpendicular to the base (bar of the T), the foot of the T of one of the wires coming to be inserted between the turns of the other wire.
- the main difficulty in forming a carcass with wires staplable, not self-staplable (see above) with transverse inertia important, is that the sections of the internal wire and the external wire do not have their axes of inertia, or their neutral fibers. equidistant from the axis of the pipe.
- the internal and external wires are placed head to tail, relative to their stapling means, which leads to the axis of inertia of the external wire being on a circle with a radius larger than that of the axis of inertia of the internal wire, unlike self-stapling wires in S or Z whose inertias of the wires coincide since the sections of the wires are identical and arranged in the same way and at the same distance from the axis of the pipe. So if the preformation of the two external and internal wires is done identically at the same radius of curvature (for example on a support mandrel), stress relaxation deformation, or elastic relaxation, can lead to the outer wire has a tendency to come off the inner thread. This could result in loss performance to withstand external pressure since the two internal wires and external do not resist jointly. In addition, the carcass may unplug very easily during subsequent manipulations.
- the stapled position of the two wires can be ensured by now one on top of the other by two rollers.
- the ratio of the areas of the internal and external wire sections can be between 0.5 and 1.5.
- the two wires can be of identical sections, in T or in U.
- One wire can be in T, the other in U.
- the invention also relates to an apparatus for manufacturing a tube.
- flexible from two spiral metal wires whose sections transverse in the shape of a T or a U have bosses laterally to the base of the U or the bar of the T, the two wires being arranged one with respect to the other so that the bosses of one wire face the bosses of the other wire, attachment takes place by partially covering one wire on the other.
- the apparatus comprises bending means constituted by at least three rollers for each of the wires, bending means each linked to a frame independent of each other and can be positioned relative to each other while retaining the adjustment of the bending rollers, means for injecting the wire in said bending means and speed adjusting means injection.
- the method applies to the manufacture of a flexible tube carcass having to withstand external pressure and not having a tube inside.
- the form wire 1 is pushed in the direction of the arrow 2 by feed means 6 for wire 1, represented here by symbolization and can be, for example, motorized rollers, caterpillars or the like.
- Wire 1 is plastically deformed by the three supports 3, 4 and 5 of the rollers 3a, 4a and 5a.
- Supports 3, 4 and 5 can be constituted by other means known and used in the profession, by example by fork type rods when the material of the wire to be preformed is more malleable.
- the respective position of the three supports gives a plastic deformation determined at said wire, so that after relaxation after deformation, the coil of wire 1 has a radius R corresponding to the radius of the final product, that is to say a carcass of stapled wires.
- Figure 1B shows a top view of the bending means so to illustrate the positioning offset of the rollers 3a and 4a relative to the first roller 5a in order to deform the wire laterally to form a helix.
- the principle of deformation is the same for an internal or external wire, except that it has been experienced that the lengths of two wires are slightly different per revolution, in particular because the diameter of the neutral fiber of the wire internal is different from the diameter of the neutral fiber of the external wire. For that, he has been found to obtain a carcass having the characteristics mechanical requirements, it is essential in the present invention to perform adequate adjustment of the feed speeds of the two wires. For that, we can calculate the lengths required per turn or measure them by winding a large number of turns (between 15 and 20) of the two internal and external wires according to the geometry determined using, ie the preforming mode cited previously, or possibly on a diameter test mandrel outside corresponding exactly to the inside diameter of the carcass to manufacture. You can use a lathe for winding, then measure the lengths consumed. This method is much more precise than a calculation theoretical. It should be noted that it is therefore absolutely necessary that the means feed wire 6 have means for adjusting the feed speed independent of each other.
- the figure 4A shows the arrangement at approximately 180 ° between the forming means 7 for the external wire 9 and the forming means 8 for the internal wire 10.
- the two means were placed on independent plates or tables allowing displacement along three axes (horizontal and vertical and inclination by relative to the axis of the pipe) of said means without modifying the positions bending rollers. It is indeed clear that we must have the means mechanical adapted to precisely orient the plane of a turn of wire by compared to the plan of the other wire to make a carcass out of wires which must fit together to staple as the preformation takes place.
- Ways feed 6 ( Figure 1A) by push are also mounted so adjustable so that the pushed wire enters the bending means according to the optimal determined angle and the radial position so as to bring the two wires tangent to the diameter to be manufactured.
- the roller 11 (FIG. 4A) represents a complementary means for the stapling of the wires 9 and 10.
- a support roller 13 is preferably added.
- Figure 2 shows in section the turns once formed at radius R required.
- the wire 10 is the internal wire whose distance from the back to the axis 12 is R
- the wire 9 is the external wire
- the flat of the bar of the T is at the distance R from the axis 12.
- the deformations for stapling, subsequent to plastic bending deformations remain in the elastic range of the yarn material so as to find the nominal bending diameters after the stapling operation. So the sons internal and external are in spirals nested with a controlled clearance, generally minimal, in the radial direction to obtain contact sufficient between the two wires, which ensures good resistance to pressure external.
- the wire here the external wire
- the spiral of the first wire (here the internal wire 10) is therefore elastically deformed in the direction of the longitudinal axis of driving before stapling.
- the relative positions of the bending means both control the elastic deformation of at least one turn in the radial direction and the elastic deformation of the pitch of the turn of a wire, the other wire passing through the space corresponding to the nominal pitch stretched elastically.
- Figures 3A, 3B. 3C and 3D illustrate the different section of wires which can be combined according to the present invention to make a carcass without internal mandrel-type support.
- Figure 3A shows the cross section of two identical internal and external wires.
- Figure 3B shows the section of two wires in T, one of which has a wider section than that of the second wire.
- Figure 3C shows the section of a T-wire stapled by a U-shaped wire.
- Figure 3D shows the section of two U-shaped wires, of identical sections but which may be of sections different without departing from the present invention.
- the different wires can be internal, or external.
- FIG. 4B shows a top view of the bending wheels, the last 3a is offset by an angle ⁇ relative to the axis of the carcass of so as to force the folding along an axis not perpendicular to the axis of the wire. So, the effect of "curling”, known in the art of winding tubes or cables with flat wires, is limited.
- FIG. 5 The two T-wires (internal wire 21 and external wire 20) are fed by the slides 22 and 23 which extend the non-pushing means visible in this photo.
- the means for bending the external wire are made up by the rollers 24, 25 and 26.
- Figure 6 The scrolling of the external wire 20 is stopped while the wire internal 21 is brought to the level and next to the wire 20. There is no hooking between the wires.
- FIG. 7 The wires are now injected continuously at speeds predetermined. Stapling begins in the area referenced 28. Note that the positioning of the wire injection axis is precisely adjusted so there is a slight crossing of the turns to initiate stapling. We play here on the elasticity of the internal thread turn.
- Figure 8 Along zone 29, the two wires are at nominal diameter and stapled.
- Figure 9 The two wires enter the space between the roller stapling 27 and the support 30.
- the external wire 20 is stapled only on one side, the other side being located laterally to the neighboring turn.
- Figure 10 From this angle, we can see in area 31 the beginning stapling the outer thread with the inner thread. Note that the mode is similar to stapling in area 28 in Figure 7.
- FIGS 11, 12 and 13 Stapling continues naturally, the thread outer now stapled on both sides.
- Figures 14, 15 and 16 The two turns each consisting of two wires stapled are now stapled together, and are pinched and held in the stapling rollers.
- the manufacturing machine used here is fixed relative to the ground, which causes the manufactured carcass to rotate on its axis as and when injection and preformation of the two wires.
- the invention is not limited to this type of experimental machine, but transposes directly to machines of wire drawing which rotate entirely around the axis of the carcass.
- the coils of wires and the bending means are shipped on a set turning whose speed of rotation corresponds to the speed of rotation of the carcass made with the machine shown here.
