Definitions
- the invention relates to a wire drawing machine for producing a drawn wire, in particular a drawn aluminum wire, with a housing, wherein a plurality of dies are arranged in the interior of the housing, wherein in the region of a wire outlet opening of the housing in the wire conveying direction after all dies a Ab faceddüse is arranged, which for generating a jet of rinsing fluid, directed substantially against the wire conveying direction, for rinsing the wire, and a method for producing a drawn wire in such a wire drawing machine.
- the invention relates to a wire drawing machine integrated in an enamel wire system, that is, wherein the wire drawing machine is a part of the enamel wire system.
- a thin wire with a cylindrical cross-section is first drawn from a wire with a relatively large cross-section in several steps, which is then coated.
- the enamelled wire basically passes through the following main components: the removal device of the preferred wire, the drawing device with a wire drawing machine to realize a required bare wire, the annealing for recrystallization of the cold-formed bare wire, the lacquerware for applying the lacquer film to the bare wire, the Einbrennschacht in Einbrennofen for drying and hardening of the paint, the cooling system for controlling the wire temperature on the lacquerware and the winder for removing the finished enameled wire.
- the process conditions in the baking oven during paint drying ie paint composition, solvent content of the circulating air, process air or wire temperature, drawing speed and flow within the furnace, are the decisive factors influencing the coating quality of an enameled wire.
- the wire drawing process is all the more important for the drawing, cleaning and annealing process.
- the so-called preferred wire with a correspondingly large raw wire diameter is first taken from a reservoir and fed via guide rollers or deflection rollers of the drawing system with one or more wire drawing machines.
- Such drawing machines usually have individually driven drawing disks over which the preferred wire is guided or tensioned. Due to the single drive of the drawing discs, slippage, which could damage the wire surface, can be minimized or even almost completely prevented.
- Between the drawing discs there are drawing blocks with conically shaped drawing stones, whose perforated cores are usually made of polycrystalline synthetic diamonds. The hole cross-sections of the cores decrease as the number of drawing heads increases, as a result of which the wire body is drawn and deformed or pulled through successively as it passes through the preferred wire. Due to the mechanical deformation of the wire in the drawing cones correspondingly low EnddrahtStarn can be realized.
- the force with which a wire is pulled through the dies is applied via the drawing disks respectively behind the dies.
- the transmission of this tensile force from the pulley to the wire is done by friction.
- the frictional force depends on the material of the pulley and the wire, the condition and the geometry of the wire support surface, the number of wire wraps, the slip and the lubricant used.
- the dies are basically intended to enable high wire throughput speeds (high drawing powers) and to provide long service lives.
- the quality of the surface and the roundness of the drawn wire must always be within the permissible tolerances.
- the drawing cone itself is subject to high frictional pressure. The internal friction created during forming in the wire and the external friction in the wire Drawing cone therefore cause a strong warming.
- a high-pressure flushing system with liquid drawing agent ensures intensive lubrication and cooling of the wire as well as the drawing dies.
- the drawing agent leads from the drawing machine caused by abrasion tinsel and other impurities.
- the liquid drawing agent / flake mixture is then continuously cleaned via a filter system (eg with a drum belt filter), which is part of a drawing agent circuit.
- a filter system eg with a drum belt filter
- the EP 0 011 612 A1 describes a system in which metal wires can be rolled flat or geometrically leveled by means of deformation rollers.
- the rolled wires can be cleaned with a plurality of nozzles arranged outside the wire at a certain angular offset along the circumference of the wire.
- the DE 20 2004 013 220 U1 discloses a nozzle for wire cleaning in forming processes for producing wires.
- the nozzle grooves are provided, which protrude into the opening of the nozzle.
- the nozzle has a conical feed section, which is formed by two conical recesses with an opening in the intersection of the cone.
- the flow paths of the flushing fluid should run in a straight line through the feed section.
- the JP H05 138244 A shows a wire drawing machine for producing a drawn wire with a very small wire diameter, and forms the basis for the preamble of claims 1 and 11.
- the DE 2 434 109 A1 shows a lubricating nozzle for generating a directed against the wire conveying direction jet for lubrication and cooling of the continuous wire.
- the nozzle opening of the lubricating nozzle is accordingly spaced from the wire and arranged in the region of a drain opening to allow lateral outflow of the fluid.
- the DE 100 58 369 C1 shows a cooling device in the form of an annular nozzle with a die.
- a liquid coolant is accelerated from an annular distribution chamber through a conical annular space in the direction of an annular gap and flows counter to the wire conveying direction through the outlet opening into the cooling chamber.
- DD 210 621 A1 an annular nozzle for stripping a cooling medium is shown.
- stripping medium pressurized water or air are described.
- the JP S60 61115 A shows a cooling device for a drawn wire, wherein the wire and a back of a drawing die are sprayed with water, which is collected in a cooling box arranged after the die, wherein the wire surface is dried with air before exiting the cooling box.
- the invention provides that in a wire drawing machine of the type mentioned in the wire conveying direction after Ab Hughesdüse a Abblasdüse for generating a substantially directed against the wire conveying direction air jet for cleaning the wire of remaining rinsing fluid is arranged, wherein in Draht designedurgicardi before Ab Hughesdüse arranged Endziehstein of the wire outlet opening into the interior of the housing and is arranged aligned on a line with the Ab Hughesdüse and the Abblasdüse, wherein the Ab Rushdüse is a wire surrounding and directed against the wire conveying direction annular nozzle, which is adapted for non-contact storage of the wire, said Non-contact storage means that the wire is floatingly supported on a rinse fluid pad formed by the jet in the rinse nozzle when the ring nozzle is pressurized with rinse fluid.
- the above object is achieved in a method of the initially mentioned type in that after cleaning the wire remaining on the wire rinsing fluid is removed by means of a counter to the wire conveying direction compressed air jet from a blowing nozzle of the wire, the Endziehstein in the wire conveying direction in front of the rinsing nozzle and offset from a wire outlet opening into the interior of the housing and arranged in alignment with the rinsing nozzle and the blow-off nozzle, the rinsing nozzle a ring nozzle surrounding the wire and directed against the wire conveying direction which is fed with flushing fluid under pressure, so that the wire is stored in the flushing nozzle without contact, floating on a Spülfluidpolster formed by the jet.
- wire travel is stabilized by the rinse nozzle.
- the beam can thereby completely surround the wire or be guided all around parallel to a longitudinal axis of the wire and along the wire surface. Due to the jet pressure of the flushing fluid and due to the directed against the wire movement beam direction high shear and thus an efficient removal, especially of coarse-grained tinsel is caused by the wire surface.
- this makes it possible to clean up flake particles and liquid drawing agent on metal wires drawn by means of drawing dies after the last drawing die by means of preferably coaxial, cone-shaped fluid jets based on highest wall shear stress on the wire surface counter to the wire running direction.
- a coaxial drawing agent jet is produced, which initially strikes the wire surface obliquely and then completely escapes at the wire inlet opening of the nozzle.
- a coaxial drawing agent jet is produced, which initially strikes the wire surface obliquely and then completely escapes at the wire inlet opening of the nozzle.
- the wire surface therefore advantageously has, after passing through the rinsing nozzle in addition to the non-cleanable, firmly pressed into the wire residues, only more of the rinsing fluid with particular fine-grained tinsel on; coarse flake particles remain in the drawing machine and do not get between wire and one of the drawing machine usually downstream Ausziehitch so that there caused damage to the wire is avoided.
- the wire after the last die is guided without contact, ie in particular without further stabilization bearing, from the wire drawing machine.
- the Ab Rushdüse can be arranged offset from the wire outlet opening into the interior of the housing.
- the blower nozzle is operated with compressed air and blows compressed air against the wire movement around along the wire surface and parallel to the wire.
- the massive shear flow removes the blob / rinse fluid mixture remaining on the wire after the rinse nozzle and the wire comes out of the drawing machine with almost no liquid coating agent coating.
- the Endziehstein ie the last and narrowest die of the wire drawing machine is thus arranged in the wire conveying direction immediately in front of the rinsing nozzle, so that no deflection rollers between the Endziehstein and Ab faceddüse are arranged. Due to the alignment of the end marker, the rinse nozzle and the blow-off nozzle in a line, the wire emerging from the end-marker is guided exactly through the center of the rinse nozzle and the blow-off nozzle.
- the flushing fluid is a drawing agent used for cooling the wire. If the same liquid is used as the rinsing fluid and as the drawing agent, the wire drawing machine does not require a new rinse cycle for the final drawdown, i. E.
- the wire drawing machine has only one rinse cycle.
- the rinse nozzle is thereby used to produce the jet with liquid and void-free drawing agent, i. with filtered or purified drawing agent liquid from the drawing machine system itself.
- the removed by the jet of Ab faceddüse baubles is preferably introduced into the drawing agent circuit of the drawing machine. That the exiting from the Abs Hughesdüse drawing with the particles cleaned from the wire remains in the drawing machine housing and runs there on the ground together with the drawing agent of previous dies in the cleaning or filter circuit.
- blow-off nozzle With regard to the blow-off nozzle, it has proved to be advantageous if it is arranged or seated directly in the wire outlet opening of the housing, so that the wire outlet opening is dynamically sealed by the air jet of the blow-off nozzle.
- the flushing fluid in particular the drawing agent, is enclosed in the housing in a particularly simple way, i. not discharged from the case.
- the blow-off nozzle is a ring nozzle surrounding the wire and directed against the wire conveying direction.
- the respective nozzle has a nozzle opening surrounding the wire in the entire circumference, from which the jet emerges.
- the nozzle has one of the annular nozzle openings substantially parallel or slight angled towards the longitudinal axis of the wire tapered to the nozzle opening nozzle channel. This type of nozzle allows a homogeneous and complete cleaning of the wire even with very small wire diameters (eg up to 0.25 mm) and a centered mounting of the wire in a wire opening of the nozzle inside and concentrically the annular nozzle opening.
- the cross section of a nozzle opening of the rinsing nozzle and / or the blow-off nozzle for the inlet of a rinsing fluid or an air jet to the wire is adjustable.
- the nozzle opening for the feed is inside the nozzle and is directed substantially (at an angle) against a wire conveyed through the nozzle.
- Different drawing machine configurations inlet and outlet diameter of the bare wire, wire metal, wire diameter, wire speed, drawing die type, number of drawing dies, type of drawing medium, fat content of the drawing agent, etc. lead to the formation of different tinsel amounts in different size distributions.
- the nozzle opening is formed between a nozzle body with an at least partially substantially conically tapering towards the wire conveying direction interior space for the transport of a rinsing fluid or an air jet and a guide member arranged at least partially in the interior, wherein the guide member is arranged adjustable relative to the nozzle body parallel to the wire conveying direction.
- the guide part can be displaceable parallel to the wire conveying direction relative to the nozzle body.
- a reliable and accurate setting of the nozzle opening can be achieved if the guide member has an external thread with which it is screwed in an internal thread of the nozzle body about an axis parallel to the wire conveying direction.
- the nozzle opening can be adjusted by turning the guide member in the nozzle body.
- a lock nut is screwed onto the external thread of the guide member, by means of which the guide member fixed to the nozzle body is.
- the guide member is tightened by tightening the lock nut substantially between the nozzle body and lock nut, so that a twisting of the guide member is counteracted.
- Fig. 1 shows a wire drawing machine 1, more precisely a so-called Inlineziehmaschine, with a housing 2 and a wire pre-cleaning system 3.
- a wire drawing machine 1, more precisely a so-called Inlineziehmaschine
- a housing 2 Inlineziehmaschine
- a wire pre-cleaning system 3 In the housing 2, a plurality of dies 4 or drawing blocks are arranged, with which the wire (not shown) to the desired shape or the desired wire cross section is deformed. Between the dies 4, the wire is guided over each individually driven pulleys 5.
- the cleaning system 3 shown here is to rid the wire after passing the last die 6 (also called Endziehstein) of tinsel without liquid drawing agent from the wire drawing machine 1 is discharged.
- the Endziehstein 6 is on a special holder 7 fixed in the housing 2, so that the Endziehstein 6 not in the context of the housing 2 (also called drawing cabinet) sits, but offset inwardly in the housing 2 itself is placed.
- a Ab faceddüse 9 is arranged, which applies correspondingly high pressure jets of liquid and tinsel-free drawing agent on the wire surface against the wire movement, ie reversed to the wire conveying direction.
- the resulting high shear causes an efficient removal, especially of coarse-grained tinsel from the wire surface, which is automatically introduced into a drawing agent circuit (not shown) of the wire drawing machine 1.
- the wire surface has after passing through the Ab Kirse 9 next to the non-cleanable, firmly pressed-drawing agent residues, only more liquid drawing agent with particularly fine-grained tinsel.
- the Ab Rushdüse 9 is a Abblasdüse 10 with compressed air connected after (see. Fig. 2 ), which sits directly in the wire outlet opening 8 of the housing frame.
- the blow-off nozzle 10 blows compressed air against the wire movement.
- the massive shear flow achieved thereby not only removes any bauble / drawing agent mixture remaining on the wire after the rinsing nozzle 9 and feeds it to the main drawing agent circuit of the wire drawing machine 1, but also seals the wire outlet opening 8 of the wire drawing machine 1 dynamically.
- the particles cleaned off with the drawing agent jet generated by the rinsing nozzle 9 pass into a main drawing agent circuit of the wire drawing machine 1, whereby no new rinsing cycle has to be installed.
- the blown into the wire drawing machine 1 due to the air jet generated by the blower 10 air can escape through vents 11 from the housing 2.
- the two nozzles 9, 10 are arranged substantially centered on a straight line defined by a longitudinal axis of the wire 12, ie, the center of a wire channel 13 of the nozzle 9, 10 is in each case on the straight line.
- the two nozzles 9, 10 each have a nozzle body 14, which surrounds the wire channel 13 for the passage of the wire 12.
- In the nozzle body 14 is a conically tapered against the wire conveying direction 15 interior 16 is formed.
- a beak-shaped guide member 17 is received, the inside of which forms a portion of the wire channel 13 and the outside of which - conically tapered against the wire conveying direction 15 - comparable to the interior 16, but slower, ie at a shallower angles against the wire channel 13.
- the inner space 16 is sealed by the guide part 17.
- the interior 16 has an inlet opening 18, to which a pressure valve 19 is connected. The introduced through the pressure valve 19 in the nozzle 9, 10 fluid, eg liquid drawing agent or compressed air, distributed in the interior 16 outside the guide member 17 and is pressed under pressure through an annular nozzle opening 20 between the guide member 17 and the nozzle body 14.
- the nozzle opening 20 has a ring cross-sectional area for the flow of the pulling means, so that the fluid in each case in an annular, the wire 12 substantially concentrically and uniformly surrounding beam exiting the interior 16, which beam continues along the wire 12 and for the most part exits through a front wire opening 21 of the nozzle 9, 10 from the nozzle 9, 10.
- the compressed air introduced through the pressure valve 19 (see air flow along the arrows 24) is directed against the wire 12 through the annular nozzle opening 20 against the wire conveying direction 15 and blows any liquid drawing agent residues to the front 23 and through the wire opening 21 from the Abblasdüse 10.
- the emerging from the Abblasdüse 10 air flow or the compressed air jet forms at the In the wire conveying direction 15 after the blow-off nozzle 10, the wire 12 is usually taken up by a pulley (not shown) and pulled out of the wire drawing machine 1 (see FIG. Fig. 1 ).
- Fig. 3 shows the rinsing nozzle 9 according to Fig. 2 more in detail.
- the guide member 17 is axially, ie parallel to the wire conveying direction 15, relative to the nozzle body 14 slidably, which is provided by a provided in a cylindrical portion of the guide member 17 external thread 26 which is screwed into a provided in the nozzle body 14 internal thread 27.
- the guide member 17 is thus axially displaceable by turning with seat in the internal thread 27 of the nozzle body 14 so that between the nozzle body 14 and guide member 17 different ring cross-sectional areas are released for the nozzle opening 20 and the cross section of the nozzle opening 20 is thus adjustable.
- a counter nut 28 with an internal thread for seating on the external thread 26 of the guide member 17 is an operating aid for rotating the guide member 17 without having to touch its external thread 26 by hand. By tightening the lock nut 28, the guide member 17 can be fixed in a certain axial position.
