Definitions
- the invention relates to an arrangement for cooling heat-treated wires with the features specified in the preamble of claim 1.
- Such an arrangement is known from DE 100 58 369 Cl. It contains a cooling nozzle through which a wire guide channel is fed, through which a coolant is fed through a lateral inlet channel, which passes through a tapering coolant channel in the nozzle and emerges from the nozzle as a current directed obliquely against the wire against its direction of travel and is discharged through a lateral outlet channel ,
- the invention has for its object to provide a particularly suitable for cooling flat wires cooling device that provides good cooling performance even with a compact structure, easy to manufacture, easy to install and easy to use. This object is achieved by the features specified in claim 1. Developments of the invention are characterized in the subclaims.
- the construction according to the invention provides for the formation of all essential parts such as nozzles, wire guide channels and coolant channels in a single, relatively flat, cuboid-shaped part, into which they are either machined from one side or preferably formed as openings in this flat part, for which a wire erosion process is particularly suitable.
- cutting out with a laser beam would also be conceivable.
- On this flat part plates can be attached on both sides, one of which is provided with openings for supply and discharge of the coolant, which lead to the corresponding recesses in the cuboid part and are expediently provided with connecting threads for the coolant hoses, while the other plate can only be a cover plate which, for example can be made removable with the aid of a suitable closure for inserting the wire.
- the coolant flows in and out from one side, for example from the rear, while the wire is inserted from the front without hoses interfering with handling.
- the coolant inlets and outlets can also run as upward and downward bores in the nozzle body and open into the corresponding channels in the interior of the nozzle body, so that the connecting hoses are not connected from behind, but from above or below. With a different orientation (rotation of the entire arrangement by 90 °), the directions change accordingly.
- the coolant is expediently fed from both sides onto the wire over its full width.
- a corresponding double nozzle contains two coolant channels, which taper towards the wire to increase the flow velocity and feed it obliquely, so that the two coolant flows impinge on the wire at a flat angle.
- double coolant inflow channels are provided on each side according to the invention, which are fed in parallel and each open into a common chamber, which continue in the form of the tapered channels which are directed obliquely towards the wire. Accordingly, two channels are also provided for removing the coolant, which run outwards from a coolant collecting chamber through which the wire guide channel passes.
- flow brakes are expediently provided in the vicinity of these points, in the region of which flow vortices arise which reduce the pressure at the entry and exit points of the wire in order to counteract leaks there.
- additional drainage channels can be provided as "overflows" for pressure relief between these flow brakes and the ends of the cooling device.
- a special embodiment of the invention is to precede the nozzle working in countercurrent to the wire guide as a pre-cooling nozzle in order to prevent coated, for example tinned wires, from the coating which is still liquid due to the heat treatment due to the heat treatment Wire which is opposite to the coolant flow can be wavy.
- the coolant flowing here with the wire builds up a counter pressure and cools the coating to such an extent that it solidifies and is no longer deformed by the subsequent counterflow from the other nozzle.
- Such a combination of co-current and counterflow nozzles together with the associated coolant channels can be easily formed in one and the same nozzle body in the invention, especially if this is formed with a central part covered with plates on both sides, in which even complicated perforation patterns can be produced relatively easily.
- this central part is also possible to adapt the thickness of this central part to the width of the flat wires to be cooled, i.e. to provide central parts of different widths depending on the wire width and then to replace them accordingly, the rear plate being retained with the hose connections and the front cover plate also remaining the same can.
- FIG. 1 shows an embodiment of the invention with a counterflow nozzle in a schematic plan view (FIG. 1 a) and a schematic cross section (FIG. 1 b);
- FIG. 2 shows individual part views of an embodiment with a co-current and counterflow nozzle, FIGS. 2a and 2b being a top view and a side view of a cover plate, FIG. 2c a top view of the central part with two end pieces, FIG. 2d the second cover plate and FIG. 2e one Illustrate top view of the central part with the recesses.
- the top view of a first embodiment of the invention according to FIG. 1 a shows a relatively narrow central part 2, which widens in a T-shape at the ends and to which side plates 4 and 6 are attached on both sides, which are closed off by the T-shaped widenings 8 ,
- the indicated screw connections 10 hold the three parts together. End pieces 12 on both sides complete the device, which can be screwed onto a mounting part via fastening bores 14.
- 1b shows the wire guide channel 16 which extends longitudinally through the central part and through which the wire (not illustrated here) runs in the direction of the arrow 18. It passes through a nozzle 20 which flushes it with a coolant against its direction of travel.
- the coolant is supplied in the direction of the small arrows via four inflow channels 22a, b and 24a, b, of which the two channels 22a and 24a open into a flat chamber 26a and the other two channels 22b, 24b open into a further flat chamber 26b.
- These two chambers are located on both sides of the wire guide channel 16 and open into tapered coolant channels 28a and 28b which run obliquely to the wire guide channel 16.
- the flow rate of the coolant increases in the sense of an improvement in the nozzle effect.
- the wire guide channel 16 is provided with a flow brake 30, which counteracts leakage of fluid on the wire exit side.
- the coolant flow flowing against the wire finally arrives in a collecting chamber 32, from which two outflow channels 34a, 36a and 34b, 36b lead away on both sides, from which the coolant flows in the direction of the small arrows. occurs.
- the coolant channel 16 has a flow brake 38 for sealing, following the collection chamber 32.
- overflows 40a, b are provided in the form of further drainage channels.
- the central part 2 with its various channels and bores can be produced relatively easily since it is initially freely accessible and is only completed by the side plates 4 and 6 on both sides.
- FIGS. 2a to 2e Another embodiment of the invention is illustrated in FIGS. 2a to 2e.
- the coolant supply and discharge to the central part 2 does not take place here as in the first embodiment from above and below, but from the side or rear via the side plate 4, which contains corresponding bores as coolant channels.
- two nozzles are provided here, one of which works in co-current and the other in counter-current.
- the arrangement here is symmetrical, the left nozzle working as a pre-cooling nozzle in the co-current and the right counter-current when the wire running direction is again assumed in the direction of the arrow 18.
- the central part 2 is here again designed as a flat cuboid with T-shaped widenings 8 at the ends, between which the side plates 4 and 6 fit.
- the screw connections are not shown here.
- the arrangement of the individual elements is best seen in Figure 2e.
- the wire running through the device in the direction of arrow 18 in the wire guide channel 16 first passes through the co-current nozzle 42, where it is protruded from both sides. is cooled.
- the coolant enters the inlet channels 23a and 23b through the openings 23c and 23d in the side plate 4 and passes through the tapered coolant channels 28a, 28b, from which it emerges with the wire running direction.
- a flow brake 30 and overflow channels 40a, 40b are provided against coolant leakage at the inlet end, which communicate with openings 40c, 40d in the side plate 4, from which coolant can be removed.
- Pre-cooling at this nozzle is recommended for coated wires whose coating has not yet solidified due to the high wire temperature.
- the coolant flow emerging from the nozzle 42 and running in the wire running direction cools the coating to such an extent that it is no longer deformed by the nozzle 20 during the subsequent counterflow cooling.
- both nozzles and associated channels The structure of both nozzles and associated channels is mirror-symmetrical here.
- the coolant enters through the openings 22c, 22d in the side plate 4 into the inflow channels 22a, 22b on both sides and in turn passes through tapering coolant channels 28a and 28b, in order then to flow onto the wire arriving in the wire guide channel 16 on both sides and countercurrently as in the first exemplary embodiment to cool.
- only simple inlet channels are shown for the sake of clarity, but double channels can also be provided, as in the first exemplary embodiment.
- three coolant drainage channels 35a and 35b are drawn on each side, from which the coolant can exit through the openings 35c, 35d in the side plate 4 and can be returned to the circuit.
- a flow brake 30 and overflow channels 40a, 40b are also provided at the outlet end of the wire.
- the individual parts can be attached to one another in an expedient manner, so that, for example, the front side plate 6 for inserting the wire into the central part 2 can be easily removed and then reattached.
- a suitable quick fastener could be provided here.
- the attachment of the central part 2 to the side plate 4, on which the coolant connections are provided, could also be designed such that the central part can be exchanged without difficulty, for example if differently thick central parts are provided for wires of different widths.
