    Wire puller
    The invention relates to a device for drawing wire with a plurality of Konenpaaren arranged in a row and arranged between cones Konenpaares 5 dies, wherein to be drawn wire from a pair of cones to the next Konenpaar runs.
    Devices of the type mentioned are usually designed as Nassziehmaschinen, wherein a central drive is provided and is carried out according to the sliding 10 wire drawing principle, ie with a slip between wire and pulley. Such drawing machines have a plurality of (drawing) cones over which the wire is guided in a looping manner and is drawn to reduce its cross section by drawing dies or drawing tools arranged side by side in wire run. Due to a tapered cross-section in the individual dies in the wire running direction 15 results in a defined wire extension. According to this wire extension of the consecutively arranged pairs of cones and the rotational speed of the same must be increased. Within a Konuspaares an increase in speed of the wire over increasing Konendurchmesserstufungen and thus adapted peripheral speed is realized on the wire running surface on the cone circumference. 20
    With conical wire drawing machines, operation of the cones with a certain amount of slip (ie a higher speed than absolutely necessary) in relation to the wire is generally essential. By setting a slip is taken into account that the cones and the dies are subject to wear, which can also vary. The slip 25 should be minimized. On the last cone pull in the pulling direction or a downstream Ab- or Ausziehscheibe but no more slippage should exist.
    The disadvantage of a fixed slip is that by the specification of a constant machine slip a total slip on the conical disks due to a predetermined predetermined technological slip in the direction of a decreasing wire diameter unfavorably increases constantly. This has a negative effect on the surface quality of the finished wire and also adversely affects the wire properties, the wear on the drawing discs, the drawing power, the energy input and the thickness of the wire the risk of wire breakage during the drawing process.
    A structural adaptation of a wet drawing device to different operating states 5 or a slip adaptation, as disclosed for example in DE 197 53 008 A1, proves to be difficult in practice and is also inflexible with respect to a change of process parameters.
    A more suitable method for determining slippage and, ultimately, a load on the wire passing through a wet-drawing apparatus is one
    Control of individual drive units, as disclosed in DE 10 2007 019 289 A1. In a wet drawing apparatus according to this document, exactly one drive motor is associated with each drawing cone. In addition, a scheme is provided, with a depending on a speed of the cones downstream Ausziehscheibe 15 control of the drive units of Ziehkonen and thus also the slip takes place.
    Such a wet drawing device makes it possible to control the slip, but the control is expensive and the device is expensive due to the required number of drives. In particular, the complexity of the control of the interacting drives and a high load on the wire to be drawn with the risk associated therewith 20 of a wire tear are disadvantageous in this wet drawing device.
    The object of the invention is to provide a device of the type mentioned, in which a simple slip on individual pairs of cones can be optimized, so fine and finest wires, especially those made of steel, with high process reliability and good surface qualities, the lowest possible twist and low residual stress can be produced.
    This object is achieved according to the invention when, in a device of the type mentioned above, a motor is provided for each pair of cones in order to drive the pair of cones 30.
    With the inventive design of a device or wet drawing machine can be taken in a simple way to changed process parameters, for example caused by wear or clogging of dies, consideration. At the same time, an expenditure on equipment is minimized at the same time as each pair of cones is driven by a separate motor. For this purpose, the individual drive units are controlled with respect to the process parameters and operated in a deviation-neutral manner, so that slippage can also be minimized. It is possible to create wires with excellent surface qualities at a high production speed. In this case, high production speeds can also be achieved because the wire to be drawn, in contrast to individually each provided with a drive and operated cones is subject to a lower load. 10 The individual cones can in principle be designed in several parts from individual discs with different diameters. Because of an easy changeability of the cones, however, it is preferred if these are formed in one piece.
    An arrangement of the cones of a pair of cones can be done arbitrarily. For example, the cones 15 can be arranged side by side. However, it is advantageous, again with respect to the lowest possible load of the wire to be drawn, when the cones of a pair of cones are arranged one above the other. In addition, can be ensured by a vertical, from bottom to top pulling direction optimal flushing of the dies. Abrasion can be reliably removed from the forming zone 20, which has a positive effect on the Ziehsteinstandzeiten.
    It has proved to be particularly advantageous if the cones are offset from one another in such a way that the wire, when transferred from one pair of cones to the next pair of cones, runs in a plane perpendicular to the axes of rotation of the cones. 25 This prevents the wire from skewing when it is transferred to the axes of rotation, which could cause additional stresses and strains.
    The individual cone pairs are preferably arranged in a plurality of chambers, wherein the chambers are flooded separately with a liquid. Usually three to 30 five pairs of cones are provided. In particular, the first pair of cones can then be arranged in a common chamber. Due to the tightness of the chambers they can be acted upon with a liquid lubricant and coolant, on the one hand to facilitate passage through the dies and on the other hand dissipate the heat of deformation resulting from the deformation. 3/12 23-03-2012 4 Printed: 26-03-2012 E014 10 2012/50097
    After the last pair of cones, at least one Endziehstein be provided, which ensures a final deformation. It is preferred that two Endziehsteine are provided, wherein the Endziehsteine are spaced apart. This makes it possible to measure the drawn wire in the region of the last die, in particular its diameter. The last end stop applying a deformation can be rotatably supported by means of a holder, so that the wire can be fed in an adjustable plane to subsequent units.
    The last cone pair is preferably followed by a Ausziehscheibe, which is preferably 10 operated without slippage. The Ausziehscheibe can be arranged so that the wire from the last pair of cones in a plane perpendicular to the axes of rotation of the last Konenpaares and Ausziehscheibe plane runs.
    In order to avoid equipment expense, it is preferably provided that the 15 Ausziehscheibe and the last pair of cones are in communication with the same engine and are driven by this. This reduces the number of motors required while at the same time ensuring good process controllability. In particular with regard to the process control, a control can be provided, with which, depending on a rotational speed of the Ausziehscheibe a speed control of the motors. Further, the Ausziehscheibe can be arranged downstream of a test disc, with softer on the wire a defined test load can be applied. This allows the wire to be tested immediately for suitability for use. It is also advantageous if the applied test load in dependence on the speed of the Ausziehscheibe is durable, in particular by a corresponding control. The test load can then be adapted to the rotational speed of the 25 Ausziehscheibe and thus the wire speed.
    Both the Ausziehscheibe and the Prüfscheibe may be frontally equipped with a co-rotating disc having openings through which an intake of air takes place during rotation of the disc. As a result, the rotation of the pulley or the test disc, which is required in any case, is used in order to naturally cool the discs themselves as well as the wire passing over them. This can be done in a particularly efficient manner, if the Ausziehscheibe and / or the Prüfscheibe are arranged in closable chambers, wherein the chambers have in the range 4/12 23-03-2012 5 of the disc or discs a corresponding recess. It is then aspirated as a fan from the outside air, which gives the desired cooling.
    A regulation of the individual motors in the engine group can be implemented particularly easily if the motors are servomotors. It can then be set in a narrow range constant tensile stresses in the wire at the transition between the individual cone pairs, so that no wire tear occurs due to overloading. Any occurring individual torque changes are recorded so that moreover, if necessary, can be regulated according to. For this purpose it can be provided that predetermined rated torques are stored or comparison torques are formed as differences of adjacent drives or cone pairs, which serve as reference values.
    Further features, advantages and effects of the invention will become apparent from the following exemplary illustration thereof. In the drawings, to which reference is made, show:

    In Fig. 1 is a schematic representation of a device 1 according to the invention, with which typically a preferably patented steel wire to a final wire diameter of less than 0.2 mm, in particular 0.08 to 0.16 mm, pulled. The device 1 comprises a housing in which the preferably three to five cone pairs 2, 3, 4 are arranged in a row or serially. The first pair of cones 2 comprises two cones 21, 22 arranged one above the other. Analogously, the subordinate cones 3.4 also each comprise two cones 31, 32, 41, 42 arranged one above the other. 6
    Between the individual cones 21, 22, 31, 32, 41, 42 of a pair of cones 2, 3, 4 die holder with dies 23, 33, 43 are arranged, through which wire 5, which is removed from a coil and the device 1 and fed through this is pulled. Through the die holder with dies 23, 33, 43, the wire passed through 5, usually a steel wire, continuously reduced in diameter, with heat of deformation is formed. The cross-sectional decreases at the first two cone pairs 2, 3 are usually in the range of 13% to 18% and are about 1% to 3% lower on the third pair of cones 4. Each die holder holds at least one die 23, 33,43, but usually several. 10
    Each individual cone pair 2, 3, 4 is driven by a motor 6, 7, 8, which in each case sits behind the pair of cones 2, 2, 4, in a manner yet to be explained. The last pair of cones 4 is followed by a Ausziehscheibe 11, with which the wire 5 is deducted from the last Konenpaar 4 with further cross-sectional reduction of about 8% to 12% 15 and 12 is fed to a further wrap around a Prüfscheibe. At the Ausziehscheibe 11 of the wire 5 is guided without slippage. At the test disk 12, a test load is applied to test the wire for operational suitability. The applied test load is variable and depends on the speed of the pulley 11 and is controlled according to their speed. Of the 20 Prüfscheibe 12, which is also operated without slippage, the wire 5 is finally fed via a publisher 17 to a winder 18, where a finished wire coil 19 can be extended after completion. For the Prüfscheibe 12 a separate engine is provided. In FIGS. 2 and 3, a device 1 according to the invention is shown in detail. The
    Device 1 has a housing which is substantially closed or lockable to the outside and comprises all components for pulling the wire 5 with the exception of a publisher 17 including a publisher motor and a spooler 18 including a spool motor. The latter components can be used as an additional modular unit in a 30 own housing, which is connected to the housing shown in FIG
    Wiring direction connects and has the same dimensions in cross section. As can be seen from Fig. 2, the device 1 has three pairs of cones 2, 3, 4, which are arranged in a row. Between the individual co-rotating cones 21, 22, 31, 32, 41, 42 of the pairs of cones 2, 3, 4, which are at the same height, there is a drawing die 23, 7 Printed: 26-03-2012 E014 10 2012 / 50097 33, 43 arranged. The inwardly tapered cones 21, 22, 31, 32, 41, 42 are integrally formed. The cones 2, 3 are held in a first chamber 9, which is shown open in Fig. 2 for the purpose of clarity. In use, this first chamber 9 is liquid-tight sealable, so that the chamber 9 can be flooded with a lubricant 5 and coolant. This is mainly the lubrication of the dies and a dissipation of deformation heat. Flooding of the chamber 9 can take place over the dies 23, 33. The further pair of cones 4 are located in a second chamber 10, which is arranged downstream of the first chamber 9. Again, there is at least one die 43 between individual cones 41, 42. In addition, the second chamber 10 as well as the first chamber 9 is floatable with a lubricant and coolant, in turn variable to the drawing die holder with the drawing or the dies 43rd
    The lubricating and cooling liquids required for flooding the chambers 9, 10 are, like the components required for circulating, arranged in a circuit within the housing. Furthermore, a not shown in detail 15 Ziehsteinhochdruckspülung is provided with which the dies 23, 33,43 are rinsed individually under high pressure with a suitable lubricant. In addition, a device for sonicating the dies 23, 33, 43 or chambers 9, 10 may be provided with ultrasound. As can be seen in the perspective view in FIG. 2, the individual cone pairs 2, 3, 4 are offset relative to one another in such a way that the wire 5 to be pulled always passes in one during the transfer from one pair of cones 2, 3 to the next pair of cones 3, 4 Level is running, which is normal to the axes of rotation of the cones 21,22, 31, 32, 41,42. 25 The actual Nasszieheinrichtung or Konenpaaren 2, 3, 4 is a pulley 11 downstream, which are arranged as well as a Ausziehscheibe 11 downstream Prüfscheibe 12 in a separate section. With the Ausziehscheibe 11 of the wire 5 is deducted from the last Konenpaar 4 without slippage, with a further cross-sectional reduction of about 8% to 12% can be done. 30 After wrapping the wire 5 until reaching a complete
    Frictionally, but at least once umschlingend out, this is fed to the test disk 12, with which a certain test load is applied to the wire 5. This ensures that the wire 5 has a required strength. The test load applied by the test disk 12 is measured in 7/12 23-03-2012 8 Printed: 26-03-2012 E014 10 2012/50097
    Depending on the speed of the Ausziehscheibe 11 regulated to take account of current conditions. Furthermore, a stretch load is advantageously applied by this arrangement, by which the wire 5 is straightened and residual stresses are effectively reduced, which is why no used in the current practice 5 roller straightening are needed, which often after a short time use bearing damage and are exposed to heavy wear. The Ausziehscheibe 11 is arranged so that similarly as between the Konenpaaren 2, 3, 4 again between the last Konenpaar 4 and the Ausziehscheibe 11 a plane is formed which is perpendicular to the axis of rotation of the drive pulley 11 and in which 10 of the wire 5 in the Handover is in progress.
    Based on Fig. 3, the drive concept is explained in detail. In cross-section, a motor 6 can be seen, which drives two shafts via a belt drive, to which end the cones 21, 22 of the first pair of cones 2 are fastened. The motor 6 is a servomotor, in particular an asynchronous servomotor. Servo motors not only have the advantage of exact controllability, but are also compact, energy-efficient and require no external cooling. The two cones 21,22 are thus operated at the same angular velocity. Analog motors 7, 8 are provided for driving the cones 3, 4 (FIG. 1). For this purpose, each motor 6, 7, 8 via synchronous 20 Zahnrieementriebe with the respective waves slip-free connection.
    A control of the device 1 via the Ausziehscheibe 11. A load torque ratio between two adjacent drives must not exceed a critical limit, which would inevitably lead to wire breakage. Due to a drawing die wear or diameter enlargements in the individual drawing dies 23, 33, 43, however, there are torque changes which are recorded during operation or transmitted by the servomotors and corrected if necessary by readjustment of the rotational speeds. For this purpose, the speed of the Ausziehscheibe 11 is determined, which in principle has to correspond to a predetermined setpoint (ideally a maximum production speed 30). In the case of corresponding deviations from the desired value, a control of the upstream servomotors 6, 7, 8 takes place so that, on the one hand, a minimization of slip on the cones 2, 3, 4 and, on the other hand, a minimization of the wire load is achieved. 8/12 23-03-2012 9
    In Fig. 4 chambers 14,15 are shown in more detail, in which the Ausziehscheibe 11 and the Prüfscheibe 12 are each arranged separately. The chambers have in addition to the Ausziehscheibe 11 and the Prüfscheibe 12 each have an underlying guide unit, so that the wire in the chambers 14,15 is similar to the cones 2, 3, 4 is guided in a loop. At the Ausziehscheibe 11 and the Prüfscheibe 12 each end face a disc 13 is arranged circumferentially has a plurality of arranged in a circle openings 16 which are formed so that upon rotation of the Ausziehscheibe 11 and the Prüfscheibe 12 air is sucked. This air is passed to the underlying Ausziehscheibe 11 and Prüfscheibe 12, so that the wire 5 as well as the Ausziehscheibe 11 and the Prüfscheibe 12 are constantly acted upon in operation with air. If a particularly homogeneous application of air is required, additional disks may be arranged behind the disks 13 which have planar webs extending in the direction of the axis of rotation and which lie between the openings 16. As a result, the sucked air is largely homogeneously directed to the parts to be cooled. In order to achieve the highest possible efficiency during suction or to increase a cooling effect, the chambers 14, 15 each have a door with which the chambers 14, 15 are lockable. However, the doors have a recess or opening whose diameter and position corresponds to that of the discs 13, so that air can be sucked from the outside, passed to the parts to be formed and circulated in the chambers 14,15, before the air through an opening, not shown escapes again.
    Furthermore, the device 1 advantageously has a leakage indicator 300 for monitoring the tightness of the conical shafts and for preventing the drawing agent from entering the bearings with the following bearing damage. For this purpose, an intermediate chamber is provided in the region of a sealing unit and a shaft bearing, over which the Ziehemittelleckagefluss collected and guided over each of the seal unit uniquely assigned lines in display container, which is clearly recognizable for a device operator leaking shaft bearing and if appropriate measures can be initiated to specifically counteract the more expensive bearing damage that subsequently ensues if the leakage flow is not recognized. Long downtimes can thus be effectively avoided.

    In Fig. 5 and 6, a Endziehsteinhalter 20 is shown in more detail. End stop stone holder 20 is mounted at the transition of second chamber 10 to that part of device 1 in which chambers 14, 15 are positioned (Figure 2). The Endziehsteinhalter 20 has two spaced Endziehsteine 44, 45 on. With these Endziehsteinen 44, 5 45 carried out the last deformation steps. The spacing of the two endstones 44, 45 has several advantages. On the one hand, it has surprisingly been found that the spacing of the endstones 44, 45 makes it possible to produce the wire 5 with improved strength properties and better surface quality. On the other hand, between the Endziehsteinhaltern 44, 45, a diameter of the wire 5 io be measured immediately before the last deformation step. From the diameter of the wire 5 can be concluded that there is wear in the die 44, resulting in a direct ratio of the reduction in cross-section distribution results directly and thus can be controlled and observed. As can be seen in particular from the combination of FIGS. 5 and 6, FIG
    Endsteinsteinhalter 20 not only separate Endziehsteine 44, 45, but the second and last Endziehstein 45 is also rotatably mounted and horizontally displaceable. For the corresponding rotation, a hemispherical sliding bearing 201 is provided, on which a component 202, 20 holding the second endstitch 45 is rotatably mounted. By means of appropriate adjusting screws 203, 204 or generally adjusting means with permanently mounted scale graduation (vernier) can be the last Endziehstein 45 rotate exactly at an angle and horizontally move or adjust and fix with fixing 205 in the einjustierten position. An adjustment is made in particular so that the wire 5 from the last Endziehstein 45 just 25 runs on the Ausziehscheibe 11. This means that the wire 5 in a plane normal to the axis of rotation of the Ausziehscheibe 11 can be guided on this. This is a great advantage because it avoids wire stresses and possible wire tears. For this purpose, the Endziehsteinhalter 20 is expediently arranged above the first chamber 14 and held in this Ausziehscheibe 11, as shown in Fig. 2 30 can be seen. Thus, all transition areas between the cone pairs 2, 3, 4 and Endziehsteinhalter 20 and Ausziehscheibe 11 and Prüfscheibe 12 are each in a plane perpendicular to the respective axes of rotation. 10/12 23-03-2012 11
    In Fig. 7 is a control scheme for controlling the individual motors 6, 7, 8 and a motor for the Prüfscheibe 12 is shown. The drive systems A6, A7, A8, A12 include the motors 6, 7, 8 and the separate motor for the Prüfscheibe 12. The reference numerals M6, M7, M8, M12 are a torque control of the individual drives 5 A6, A7, A8, A12 with assigned to the motors 6, 7, 8 and the Prüfscheibenmotor, the
    Reference numerals V6, V7, V8, V12 of a speed control. The translations ie, Ϊ7, ie, i 12 and the slip factors s6l s7, s8, s12 are indicated accordingly.
    In order to limit the unfavorable case of a continuous slip accumulation over all stages 10 of the transformation and to make all settings of the device 1 on their regulation independently, can be dispensed with additional sensors completely and the device 1 still produced adapted to an optimal operating condition is a Control provided in accordance with FIG. 7. In order to control a slip-reduced operation of the device 1 or 15 wet drawing machine, a decoupling of the individual drawing stage groups is provided structurally, which takes place via a separate drive by asynchronous servomotors. A load distribution is adapted via suitable parameters. The motors 6, 7, 8 are operated by servo controllers and are equipped with a feedback in the form of absolute encoders (encoders) or resolvers 20
    In contrast to a frequency converter, a servo controller has much faster possibilities of intervention, because in addition to the voltage amplitude and the frequency, a phase position of the current can also be changed. In particular, the possibility of intervention on the phase position very fast current and thus 25 torque changes are possible. This in turn is a prerequisite for a dynamic drive behavior, which is required if the superimposed speeds or torques should or must be set dynamically. The applied in the device 1 servo control concept is done with a deposit of a motor model in the servo drive, so that the magnetization and the active component of the motor current 30 can be controlled independently. This significantly improves the dynamic properties of the controller.
    Since, due to the function, the drawing process is always to be operated with a device 1 with a certain amount of slip, it is expedient to apply a single slip over the individual geometries
    Provide basic slip on the order of about 2%. The start-up of the device 1 is therefore carried out with a pure speed control. The control of the rotational speeds takes place in a simple manner via the rotational speed of the Ausziehscheibe 11, which predetermines a reference value or a maximum production speed. The 5 Prüfscheibe 12 can be performed when starting to achieve optimum wire qualities already on the torque. Thereafter, after achieving stable production conditions, it is expedient to proceed to a torque-controlled operation of the motors 6, 7, 8. This transition can be done manually or automatically. Although in a sliding drawing process no complete io adhesion may occur, otherwise there is inevitably a wire tear in the device 1 and a slip measurement is not possible, since there are no suitable systems on the market, which can detect the wire speed at all drawing levels under process conditions by measurement , can be achieved with the speed or torque information or the corresponding waves without 15 sensory systems an adaptation to changing conditions (process parameters and / or tool state changes) and thus an optimized production speed while avoiding a wire tear.
    With a control scheme according to FIG. 7, the following method can be implemented in a device 1: - Approaching the device 1 at a predetermined speed, which is determined by the speed of the pulley 11 for all cones 21, 22, 31, 32, 41, 42 ; - Operating the device 1 in the speed-controlled range until stable production conditions; 25 - then optional change to a speed-controlled operation of the motors 6, 7, 8 12/12 23-03-2012
