Definitions

  • the invention relates to a device for continuous Cooling a heat-treated wire.
  • Heat treatments are common to manufacturing wires to impart the desired properties.
  • a known method for this is inductive annealing, at which the wire to be treated in a short circuit loop is passed through a toroidal transformer and the secondary winding of the transformer.
  • the one from the primary winding the voltage induced by the transformer leaves in the shorted Secondary winding flow a current that is appropriate Selection of the appropriate parameters for heating the Wire leads to the desired annealing temperature.
  • Annealing temperatures can be achieved in a free atmosphere will at least lead to undesirable surface changes the part of the annealing section where these temperatures are present, covered with protective gas. That's why before winding up rapid cooling required to be outside the annealing range To prevent surface changes and also at Avoid wrapping shrinkage.
  • DD 210 621 is an annular nozzle for wiping the cooling water of rolling stock known
  • the housing one to the incoming Rolling material has a funnel-shaped tapered nozzle head, in which is centrally adjustable in a basic body in the longitudinal axis arranged, enclosing the rolling stock and at the free end tapered guide piece is provided.
  • the nozzle head and guide piece become a cone-shaped annular space formed, which ends in an annular gap, from which an am Wiping medium (pressurized water or air) is blown onto the incoming wire.
  • an am Wiping medium pressurized water or air
  • a similar ring nozzle is known from DE-OS 24 34 109 A1.
  • the cooling water flows from a conical spray gap around a hollow truncated cone or funnel-shaped cooling nozzle body around in the form of a hollow-cone-shaped beam which is directed against the inlet cone of a wire guide nozzle is directed through which led the wire emerging from the cooling nozzle body becomes.
  • the cooling water enters through a side opening an annular space, which is in the conical spray gap continues, and flows again through a side opening in the housing from.
  • the invention is therefore based on the object of a device for effective cooling of heat-treated wires with low To create space immediately before the short-circuit role can be arranged and thus the loop resistance minimal affected.
  • cooling nozzle By integrating a cooling nozzle with a cooling chamber the cooled wire to the desired size in a small space Further processing temperature, for example for winding on a Wire roll, cool down.
  • a particularly effective cooling can be by the counterflow method, in which the cooling medium fed to the wire against its direction of advance becomes.
  • the wire runs axially through the cooling nozzle has a ring opening concentric to the wire, from which Cooling medium, for example water, emulsion or cold air, flows against the wire entering the nozzle from the cooling chamber.
  • Cooling medium for example water, emulsion or cold air
  • the cooling nozzle is expediently provided with one end tapered core and a sleeve with a corresponding Inner cone, into which the cone of the core protrudes, so that a cone-shaped annular space is created which ends in an annular gap at the inlet opening of the wire.
  • the opposite end of this annulus preferably goes in a distribution annulus for the cooling medium in the radially opens an inlet opening for this medium, resulting in a short overall length.
  • the shell thickness is slightly larger than the cone angle of the core of the conical annular space to the cone tip less and the inflowing cooling medium according to the reduction in cross section accelerated: in the case of a gaseous medium there is also a compression effect that occurs when Relax the medium emerging from the annular gap to a Cooling leads, which benefits the wire cooling.
  • the annular gap is made adjustable by for example, the core is slidable with respect to the sleeve becomes. With the help of a screw thread between the core and Sleeve can easily achieve this. To fix the desired one You can still use a lock nut on the setting Provide thread.
  • the conical sleeve can expediently be designed such that the part surrounding the cone tip protrudes into another sleeve, with which it is preferably screwable and which forms the cooling chamber.
  • the one to be cooled runs through these Wire entering from the side opposite the cone, through, and the cooling medium flows after leaving the Inject the wire into it. Through one in the cooling chamber outlet opening it can leave it again.
  • a threaded connection allowed between core and cooling chamber sleeve expediently an adjustment of the axial length of the cooling chamber, and also here a lock nut can be used for fixation.
  • the device according to the invention consists of a few, relatively easy-to-manufacture parts that simply become a compact Have unit assembled that is a highly efficient and in adjustable cooling of annealed wires. Suitable liquid or gaseous can be used as the cooling medium Media are used so that also from this point of view from versatile design options with regard to the application given are.
  • the invention contains Cooling device a nozzle, which by two conical Parts, namely by a trained with an inner cone 4 Cone sleeve 6 and one with an outer cone 8 Core 10 and an opening 2 is formed. With a dash-dotted line, a wire 12 is indicated, which runs through the opening 2 from right to left in the drawing.
  • the outer cone 8 of the core 10 is something with a smaller angle of the inner cone 4 of the conical sleeve 6, so that a conical annular space between these two cones 14 is formed, which becomes thinner towards the cone tip, so that its cross-sectional area not only due to the reduction in diameter, but also due to the thinning surface area reduced and that from the large diameter side coolant flowing in towards the cone tip is even stronger is accelerated, which increases the nozzle effect.
  • the cooling medium symbolized by arrows 16, 18 passes through an inlet opening 20 into an annular distribution chamber 22 one located between a cylindrical portion 24 of the core 10 and a cylindrical bore 26 of the conical sleeve 6 is formed becomes.
  • the cooling medium enters from this distribution chamber 22 the wide end of the annular space 14, in which it is due to the explained cross-sectional reduction is accelerated and with correspondingly higher speed from the at the narrow end of the Annular space formed 3 emerges and the opposite the flow direction entering the passage opening 2
  • Wire 12 flows around and effectively cools.
  • the cooling medium arrives then into a cooling chamber 28 through which the wire 12 passes through, and leaves the cooling chamber through an outlet opening 30, as illustrated by arrow 18.
  • the wire 12 enters the cooling chamber 28 through an inlet opening 32 a in an end wall 34 of a cooling chamber sleeve 36 is formed.
  • a drawing die 56 can be used if desired.
  • the outlet opening 30 is through a side opening of the Cooling chamber sleeve 36 formed.
  • the cooling chamber sleeve 36 is provided with an internal thread 38, in which the cone sleeve 6 with one containing its inner cone 5 Stub 40 is screwed.
  • Threaded lock nut 42 allows the two sleeves 6 and 36 in one set with the help of the thread 38 mutual position. In this way the axial length of the cooling chamber and thus the residence time of the Adjust the wire in this.
  • Another setting parameter is the conical annular space 14, by more or less deep immersion of the outer cone 8 can be set in the inner cone 4. This happens also with the help of a thread, namely an external thread 44, with which the core 10 in an internal thread 46 of the conical sleeve 6 is screwed in.
  • the desired position can also be found here fix with the help of a lock nut 48.
  • the radial inlet and Outlet openings 20 and 30 expediently for the cooling medium formed with threads, in which connection nipple for Hoses or lines can be screwed in.
  • a coolant can e.g. Liquids such as water or suitable Use emulsions that are recycled can.
  • two or more cooling nozzles can also be used in succession order if e.g. thick wires not in one Stage can be cooled sufficiently or if a slower Cooling in smaller temperature steps is required becomes. In such cases, several units would be in accordance Fig. 1 or 3 - seen in the wire running direction - one after the other provided and possibly with different coolant Temperature fed.
