Definitions
- the invention relates to the packaging of pre-dressed copper alloy wires, in the form of barrel crowns, and for uses which may in particular require straightening the wire before use.
- the generic term "wire” will only be used in the following to designate all of the long semi-finished products available in the form of crowns, even those of non-circular section.
- a plastic washer is applied to the upper turn of the wire, which is attached to the bottom of the barrel by means of an elastic band, which keeps the product in place.
- This technique is applied to wires for welding in highly cold worked steel, of mechanical strength typically between 600 and 1200 N / mm 2 and of diameter ranging from 0.8 to 1.6 mm.
- the pre-dressing technique allows the pre-trained wire to slide correctly in a sheath several tens of meters long, which makes it possible to supply a mobile welding station from a heavy wire storage unit, which it remains fixed.
- the invention aims in particular to improve the current icro-turning technology of copper alloy semi-finished products, in particular brasses.
- micro-turning there are two types of machines or methods:
- Type 1 those where machining is carried out in particular by a rotating tool, the material being fixed,
- Type 2 those where the fixed tool applied to a rotating material, as for example described in the patent application
- the material is in rotation, the tool remaining stationary. This requires that the material presents itself in the form of sections of relatively short length (generally 3 to 4 m) and sufficiently straight so that they can be rotated.
- Method A Bars are made by the wire producer using straighteners.
- the micro-turning machine is then provided with a "bar tank” called a "bar feeder” intended for supplying the micro-bar turning tool with bars.
- a "bar tank” called a "bar feeder” intended for supplying the micro-bar turning tool with bars.
- This technique has drawbacks: * due to the existing technology of bar feeders and bar turning, the straightness of the bars must be perfect, otherwise the bars get stuck in the bar feeder, or else they cause vibrations during setting rotation, source of unacceptable geometric defects on machined parts.
- the producer packages the wire in crowns, the unit weight of which is generally 250 kg.
- the crowns are placed in cylindrical cardboard drums, closed at the bottom by a wooden base, and at the top by a removable cover in wood or metal.
- a drum contains about 10,000 m of wire, representing several thousand bars.
- the autonomy of the towers is multiplied by a factor of around 100 compared to that of method A.
- the length limit of the bars is no longer linked to the requirements of transport and packaging, but to the available space in the bar turning workshop. It is thus possible, at least theoretically, to machine longer bars, and thus to reduce the implementation (drop rate less than 5%).
- Method B has therefore found increasing favor among micro-turners, in particular those who work on large series where the need for high productivity is imperative.
- method B has the following disadvantages: a) unlike method A, where the producer of brass wire is equipped with a limited number of straighteners to produce bars, the bar turner must install a large number (a straightener for each round).
- the dressers must therefore be of a relatively simple model, unless it represents an extremely high investment.
- the straightness of the bars is not perfect, the precision of bar turning is not optimal (10 ⁇ m range: nominal value * 10 ⁇ m, nominal value -10 ⁇ m, or nominal value * / - 5 ⁇ m depending on the case).
- method B is limited to wires which are relatively easy to dress, since the wires of high diameter and high mechanical strength cannot be trained properly.
- method B cannot be applied to wires of diameter greater than 3 mm, or even less in the case of wires of high mechanical strength (typically of the order of 700 N / mm 2 .
- the invention aims to propose a packaging of copper alloy f, typically brass, which eliminates the drawbacks previously indicated for methods A and in particular those listed under a) to d) for method B, namely: 1) removal of one dresser per turn,
- the packaging according to the invention which overcomes the problems encountered at the bar turner, does not significantly increase the constraints p for the yarn producer.
- a first object of the invention is constituted by packaging in a cylindrical barrel of prewound metallic wire characterized in that said wire is an alloy copper, of diameter less than 10 mm, and of mechanical strength between 400 MPa and 750 MPa, so that said unwound wire is straight, with an arrow less than 5 mm per meter, and can directly feed a turning machine .
- said unwound, straight wire with an arrow less than 5 mm feeds a bar turning machine provided with a straightener.
- the wire has a deflection of less than 0.5 mm / m, a level which may be necessary for high-precision machining.
- brass is preferably chosen, taking into account the use (bar turning) which is made of the pre-erected wire of this first object, but as will be indicated below, other alloys more " hard "or more” brittle “than brass are usable.
- the upper limits of diameter and mechanical resistance of the pre-erected wire result in particular from the need to limit the energy stored by the pre-erected wire during placing in the barrel. Beyond a certain threshold, the stored energy would be too large to be contained by the frame of a barrel, and could even present a danger in the event of a barrel rupture, leading to the total release of constraints.
- the invention solves a problem of productivity and / or level of quality of great economic importance. Furthermore, the solution to this problem could not be anticipated or suggested by the means mentioned in the prior art and relating to the conditioning of steel wire for welding.
- wire dressing is perceived as an essential operation, inseparable from machining according to method B. The possibility of eliminating wire dressing cannot come to mind of this skilled person.
- this person skilled in the art is different from that of welding, and a means known in the field of welding of steel wires cannot constitute general education or teaching in a neighboring field for the man of the brass wire turning industry.
- Another object of the invention is constituted by the packaging in a barrel of pre-erected metal wire characterized in that said wire is a wire for EDM generally comprising an outer layer of Cu-Zn alloy, with a diameter between 0.15 mm and 0.35 mm, and of mechanical strength between 500 MPa and 1100 MPa, so that said unwound wire is straight, with an arrow less than 30 mm per meter.
- wires for EDM is described in numerous patents, for example in European application n ° 526 361-Al in the name of the applicant.
- the Applicant has found that the solution found with the wire for bar turning also applies to the wire for EDM.
- the technical problem to be solved is as follows: when the wire breaks, the wire must be threaded automatically, so that EDM can continue without the need for manual intervention.
- the EDM wire must not have any memory effect which means that the end of a wire initially in coil or in crown, tends to form a loop winding on itself. Thus, after breakage of the wire, the end of the wire retains its trajectory as if there had been no breakage of the wire.
- the problem has been resolved by heat treating the wire and / or straightening it before winding.
- the invention allows the elimination of these treatments, and avoids the use of coils, with the constraints linked to their use.
- the use of spools limits the quantity of thread per spool (standard weight of 5 kg), even if this quantity tends to increase.
- the coils must be mounted on a motorized reel, which generates both additional costs and vibrations incompatible with the precision of EDM machining.
- drums of significant unit weight can be used without a motorized reel
- drums can be reused a large number of times, because the packaging operation does not cause significant mechanical stress
- drums can be made of recyclable materials such as cardboard and steel.
- FIG. 1 represents a schematic section of a device for pre-dressing a wire to be pre-dressed (1) which successively comprises: * a system for unwinding (4) a wire for pre-dressing (1), and its puppet reel regulation ("dancer" in English) (5),
- Figure 2 shows in section the final packaging of the crown (15) of pre-erected wire, so that there is no tangling of the wire turns during transport:
- a plastic washer (10) is held pressed against the upper part of the crown (15), thanks to hooks (11), an elastic band (12), and a rigid rod (13) hooked by a ring (14) at the bottom of the barrel (3).
- the hooks (11), the elastic (12) and the rigid rod (13) are put in place to hold the wire during transport and storage before use. They are removed, when using the wire, to allow the turns to unwind.
- FIGS. 1 and 2 Another object of the invention is, as shown in FIGS. 1 and 2, the preparation of a package of pre-erected wire (2) described above in which, so as to obtain a pre-erected metal wire in a cylindrical barrel (3), in which, a) the pre-dressing wire (1) passes through a series of dressing rollers (6), being driven by a large diameter capstan (7) retaining its straightness over the wire, b) then said wire is subjected to a twist by crossing two pairs of non-motorized rollers (8) located in two planes perpendicular and rotated around the wire, c) said wire (2), guided by a drum (16) of the same rotational movement, is deposited in a spiral in the bottom of the barrel (3), d) said barrel (3) descends as it fills so that the interval between the free surface of the wire and the base of the drum remains constant.
- the Applicant has therefore adapted a known process for the preparation of pre-dressed wire according to the invention.
- the invention makes it possible to ensure hermetic storage of the ring of pre-erected wire (15), which avoids the risks of corrosion under stress of the wire ("season cracking "in English), in a humid atmosphere or in the presence of ammonia.
- Other means can also be used to further limit these risks: placement of desiccant sachets, or products capable of fixing the ammonia, or protective products adsorbing on the surface of the wire, insulation of the drums making it possible to limit the impact of variations in ambient temperature.
- Another objects of the invention are constituted by the use of a packaging of pre-erected wire according to the invention to directly supply wire to machining machines, in particular lathes and turning machines, or form by cold striking, and by the use of a pre-dressed wire packaging according to the invention to supply wire to an electroerosion machining machine.
- the invention also includes the use of a packaging of any pre-erected metal wire, whether it is steel wire, or a non-ferrous alloy other than copper, to directly supply wire to machines for machining, in especially lathes and lathe machines, or cold-forming machines.
- a packaging of any pre-erected metal wire whether it is steel wire, or a non-ferrous alloy other than copper
- the Applicant has been able to verify the applicability to steel wire, of the concept developed with copper alloys, such as brasses, and exposed previously.
- the running speed of the wire was 250 m / min and the speed of rotation of the pair of rollers (8) and the drum (16) was 130 revolutions / min.
- This wire was packaged in a 250 kg useful drum (3), as shown in Figure 2.
- This barrel must have a sufficiently large diameter not to impose on the wire a curvature which would go beyond its elastic limit.
- this diameter will be 510 mm in the case of a wire of small diameter ( ⁇ 1 mm), 580 mm in the case of a medium wire (diameter of the order of 1.8 mm), and 620 mm in the case of a wire of the order of 3 mm.
- bars of 4 were obtained having a maximum value of 0.5 mm of flé per meter, which corresponds substantially to a straightness level of bars obtained according to method A.
- the accuracy commonly accessible with a boom of close to 4 mm / m is 10 ⁇ m, while that accessible with a spreader of 0.5 mm / m or less of the order of 5 ⁇ m.
- the productivity gain is approximately when we go from a bar of 4mm / m of arrow to a bar 1mm of arrow or less.
- the Applicant has carried out numerous other tests varying the nature of the copper alloy and geometric or mechanical characteristics, the machining techniques, and the geometry of the parts machined.
- the wire p erected according to the invention made it possible to avoid the thermal treatment of the crowns necessary to erase “the brass memory. ", and to obtain, without heat treatment, traps with an arrow of 0.05 mm, for a tolerance of 0.07 mm.
- the Applicant has also used the pre-erected wire according to the invention to manufacture parts, no longer by factory but by cold stamping. She also observed that, in the case of very long pieces, typically from 30 to 50 the problem of deflection also arises, due to the residual deformation caused during the bending preceding the placing in barrels, and can lead to the reject of the final part, in spite of repeated adjustments of the dressing device. In this case also, the pre-erected wire of the example made it possible to considerably limit the value of the arrow.
- a typical example of parts obtained by cold stamping, taking into account tight geometrical tolerances, are the anodes of alkaline batteries.
- test tests also related to wires of different diameters (tests with brass wires of 3 and 6 mm in diameter), and of different mechanical strengths: "hard” or “brittle” alloys such as lead bronze (Cu-Sn-Pb), or lead nickel silver (Cu-Zn-Ni-Mn-Pb), within the limits as they appear in claim 1.
- "hard” or “brittle” alloys such as lead bronze (Cu-Sn-Pb), or lead nickel silver (Cu-Zn-Ni-Mn-Pb), within the limits as they appear in claim 1.
- This wire according to the invention has been tested on an electro-erosion machine, compared to a standard wire.
- a standard wire includes a thermal or mechanical dressing treatment before winding.
- the barrel wire according to the invention behaved in a manner similar to that of the coil wire, heat treated mechanically dressed, according to the prior art.
- the invention solves problems encountered by several types of users and in several types of trades: that of bar turning and those of electro-erosion, and also those of shaping by cold striking.
- the improvement relates either to the production schedule of parts for all uses, for example connectors, and therefore productivity, or to the superior final quality of these parts, or to the lower level the investment for manufacture, or on a combination these advantages.
- the invention is a synthesis of known methods, previously designated by A and B, after eliminating the drawbacks associated with each of these methods
- the client practicing the Vietnamese leafa does not have to worry about the straightening of the bars, o at the same time, the client practicing electro-erosion does not have to worry about the presence of residual spiral in case wire break.
- the supplier of f does not have to use heavy means.
- the pre-dressing means used are easily integrated at the tail end of the wire drawing without reducing the wire drawing productivity or increasing the production costs, and moreover they constitute a much lower investment than industrial dressers. Overall, if a means of pre-dressing remains necessary for the wire producer, on the other hand, it is no longer necessary to have, at the bar turner, a dresser for each tou which is a considerable saving.
- the dressing operation can be broken down into two stages:
- pre-dressing carried out by the yarn producer. This is done at high speed (typically, from
- finishing dressage which is optional, carried out by the user.
- This neat finishing dressing is carried out at low speed (typically 0.1 to 0.5 m / s), allowing good dressing quality with an inexpensive device.
- a low speed does not constitute a handicap because the dressing is carried out in masked time, the limiting step being situated at the level of the machining.
- the economic nature of the dressing device is imperative, the bar turner having to equip each of its turns with a device of this type.
- Such a configuration reduces the size of the machine, reduces the circulation and handling of drums, the risk of accidents or shocks.
- the advantages provided by the invention are also important: * by eliminating thermal or mechanical dressing treatments, * possibility of a higher unit weight and therefore greater autonomy, the weight of wire per spool being typically 5 kg, while the weight per drum is not limited. * elimination of the reels, which require motorized reels, and which, after a limited number of rotations must be destroyed, while the drums can be reused a large number of times.
- the packaging according to the invention makes it possible, for equal barrel size, to double the quantity of wire, relative to the packaging traditional barrel wire (500 kg according to the invention instead of 250 kg according to the prior art). This is due to the fact that, in traditional packaging, the turns must be relatively "ventilated” so as to limit the problems of entanglement during reeling, while all the turns are entirely blocked and with a compact stack in the case of the invention.
