Definitions

  • the invention relates to a device for pulling wire according to the preamble of claim 1 (see, for example JP-A-63010020 ).
  • Devices of the type mentioned are generally designed as Nassziehmaschinen, wherein a central drive is provided and is carried out according to the sliding 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 tapering cross-section in the individual dies in the wire running direction 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.
  • a Konuspases an increase in speed of the wire over increasing Konen shedrstufonne and thus adapted peripheral speed is realized on the wire running surface on the cone circumference.
  • the disadvantage of a fixed slip is that due to the specification of a constant machine slip, an overall slip over the conical disks due to a required predetermined technological slip in the direction of a decreasing wire diameter increases unfavorably. This has a negative effect on a surface quality of the finished wire and negatively affects the wire properties, the Ziehinverschl embodiment, the system-related drawing ability, the use of energy and the risk of wire breakage during the drawing process.
  • a structural adaptation of a wet drawing device to various operating conditions or a slip adaptation, such as in the DE 197 53 008 A1 disclosed proves to be difficult in practice and is also inflexible with respect to a change of process parameters.
  • a more suitable method for determining a slip and ultimately also a load of the wire passing through a wet drawing device consists in a regulation of individual drive units, as described in US Pat DE 10 2007 019 289 A1 is disclosed.
  • a wet drawing apparatus In a wet drawing apparatus according to this document, exactly one drive motor is associated with each drawing cone.
  • a scheme is provided, with which a control of the drive units of the drawing cones and thus also of the slip occurs as a function of a speed of the cones downstream Ausziehsort.
  • 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.
  • the complexity of the control of the interacting drives and a high load on the wire to be drawn with the associated risk 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 lower Internal stress can be produced, and in the natural way, a cooling of the outgoing wire is achieved.
  • the individual cones can basically be designed in several parts from individual disks with different diameters. Because of an easy changeability of the cones, however, it is preferred if these are formed in one piece.
  • the cones of a pair of cones are arranged one above the other according to the invention.
  • the cones are offset from each other so that the wire passes in a transfer from one pair of cones to the next pair of cones in a plane perpendicular to the axes of rotation of the cones plane. This avoids that the wire must be inclined at the transfer 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 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.
  • 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 followed by a Ausziehin, which is preferably operated without slippage.
  • the Ausziehefficiency 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 Konenpackes and Ausziehin plane runs.
  • the Ausziehefficiency 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.
  • a control can be provided, with which, depending on a rotational speed of the Ausziehscale a speed control of the motors.
  • the Ausziehfactor downstream of a test disc with which a defined test load can be applied to the wire. 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 pulley is durable by a corresponding regulation. The test load can then be adapted to the rotational speed of the Ausziehefficiency and thus the wire speed.
  • Both the Ausziehefficiency and the scholar are frontally equipped with a co-rotating disc having openings through which an intake of air takes place during rotation of the disc.
  • the already required rotation of the Ausziehefficiency or the scholar is used to cool the discs themselves, but also on this running wire in a natural way.
  • This can be done in a particularly efficient manner when the Ausziehefficiency and / or the striglet are arranged in closable chambers, wherein the chambers in the area the disc or discs have 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 readjusted. 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.

  • Ausziehitch 11 of the wire 5 is guided without slippage.
  • 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.
