Definitions

  • the present invention relates to a method for hardening a clothing wire for processing textile fibers and an installation therefor, wherein the clothing wire has a series of teeth arranged in its longitudinal direction, and wherein the clothing wire for contact with at least one open flame through a heating area in a passage direction is passed, wherein connect to the heating region, a quenching bath with a quenching liquid and a subsequent starting device.
  • Garnish wires have a sawtooth profile and are mounted on cylindrical drums or rollers to form a card.
  • the cards are provided with a toothed mantle surface, and the use of a garniture wire can be used, for example, to form a spool or pick-up and can be several kilometers in length.
  • methods for curing the clothing wire are known, which are based in particular on a flame hardening.
  • the hardening process preferably uses an open flame to form a heating region, through which the clothing wire is guided in its longitudinal direction.
  • the heating region can be preceded by a rinsing chamber, which enables at least partial cleaning of the clothing wire.
  • the clothing wire After passing through the heating zone, the clothing wire must be quenched by passing the clothing wire into a quench bath filled with a quench liquid. Subsequently, the clothing wire can be passed through a starting device and by a subsequent cooling device to the starting device.
  • Roller can be at a verzunderten surface of the clothing wire
  • a method for curing a clothing wire in which it is proposed to carry out the curing process itself with the exclusion of oxygen.
  • protective gas is to be entered into the heating area, wherein only enough oxygen is added to form the open flame, as required for the reaction with a fuel gas.
  • a mixing device is proposed, so that the fuel-air mixture burns so that no unburned oxygen reaches the clothing wire.
  • the atmosphere in the heating area should be kept free of oxygen, for which purpose the protective gas is thus additionally introduced into the heating area.
  • the object of the invention is the development of a method for curing a clothing wire for the processing of textile fibers, which allows a scale-free surface of the clothing wire despite a simple construction of a system for curing the clothing wire.
  • the expensive rinsing of the heating area should be avoided with a protective gas.
  • the invention includes the technical teaching that the clothing wire moving in the wire running direction is in a transfer area between the contact area with the open flame and the inlet to the quenching liquid is washed with a protective medium.
  • the invention is based on the idea that the clothing wire between the open flame and the immersion in the quenching liquid is washed with a protective medium to avoid contact of the clothing wire with oxygen even after passing through the Garniturdrahtes by the heating area. Investigations have shown that even after the clothing wire has come out of the heating region, the temperature of the clothing wire is still so high that reaction of the material of the clothing wire with oxygen can subsequently also lead to scaling of the surface of the clothing wire. The scaling of the clothing wire is not carried out in the heating area itself but only after leaving the heating area, which is effectively avoided by the inventive washing around the clothing wire with a protective medium.
  • the method according to the invention for hardening a clothing wire makes it possible to provide a scaling-free clothing wire in a simple manner.
  • the prior art can be dispensed with an elaborate heating chamber or oven, within which the flames are generated, and the invention must not be kept free of oxygen.
  • the clothing wire in the transfer region between the heating region and the quenching bath, can be lapped with nitrogen, which forms the protective medium, whereby alternative protective media can also be used, in particular inert gases.
  • nitrogen which forms the protective medium
  • alternative protective media in particular inert gases.
  • Important in the formation of the transfer area is the immediate transfer of Garniturdrahtes from the open flame in the transfer area to immediately wash around the clothing wire with nitrogen. Equally important is the direct transfer of the clothing wire from the nitrogen atmosphere into the quench liquid.
  • the transfer area is therefore designed such that the clothing wire is transferred from the open flame directly into the protective medium, and from the transfer area of the clothing wire must be transferred directly from the protective medium in the quench liquid.
  • the transfer area can be enclosed, for example, with a protective chamber into which the protective medium is introduced.
  • the transfer area must be minimized in the wire running direction to provide a sufficient distance of the quench bath from the heating area so that the quench liquid in the quench bath does not heat up through the open flame of the heating area.
  • the protective chamber may be box-shaped or, for example, also rohrformig, and the introduction of a protective medium can take place via a control valve.
  • the introduction of the protective medium into the protective chamber can be carried out so that the protective medium flows through the protective chamber counter to the wire running direction.
  • the protective chamber may be under pressure by the introduction of the protective medium, and wherein the protective chamber may have an inlet opening through which the clothing wire enters the protective chamber and through the inlet opening can simultaneously escape the protective medium from the protective chamber against the wire running direction, for example in the heating region.
  • the protective medium can be entrained by the open flames, and be sucked through a hood.
  • the protective medium can not or not exclusively by a gas but by a liquid, for example by the quenching liquid from the quenching bath, are formed.
  • it may be provided to bring the quenching liquid for bridging the transfer region counter to the wire running direction in the direction of the heating region and preferably substantially up to the heating region.
  • the quenching liquid can bridge the transfer area without the quenching bath itself projecting up to the heating area.
  • the quench liquid can be brought to the heating region with a flow movement in a flow direction from the quench bath, the flow direction being opposite to the wire feed direction of the clothing wire.
  • the bridging region can be formed by a wire feed pipe or by a wire feed trough, through which or through which the quenching liquid runs counter to the wire running direction.
  • the inlet opening to the inlet of the clothing wire in the wire tube or in the wire trough can zoom down to the heating range, and the outgoing quenching liquid can be collected via a collecting device and returned to the quench. Due to the flow in the quench liquid is achieved that they are not significantly heated by the hot, incoming Garniturdraht or by the flames due to their constant exchange.
  • the clothing wire can be passed through the heating area such that the tooth structure of the clothing wire points in the direction of the open flame.
  • the open flame in the heating range can be brought from above or from below to the clothing wire.
  • the transfer area has a wire tube through which the Quenching liquid is fed to a pipe inlet opening, so the open flame can burn up and the clothing wire is located at a distance above the open flame.
  • the transfer area has a wire runner, the open flame can alternatively also be directed downwards and can be brought up to the gutter or even cover it slightly, so that the clothing wire from the open flame runs directly into the wire runner filled with quench liquid. In particular, this can produce an overlap between the open flame and the wire runner, which is preferably minimized, but the transition of the clothing wire from the open flame into the quench liquid is made possible without the use of inert gas safely in the absence of oxygen.
  • the clothing wire may also be arranged in the unwound direction, i. one side surface of the clothing wire points to the open flame, the opposite side surface away from it.

  • the wire trough may for example be designed to be open at the top, and the upper flame of the heating region may extend to the end, in particular with a slight overlap, over the wire trough so that the clothing wire can enter the quench liquid directly from the open flame.
