The invention relates to a wire reel with water cooling, which has a winding plate with two or comprises several concentric rows of pins and in which the incoming, hot rolled wire about .zentrisch or spray nozzles distributed around the circumference is acted upon radially. It is known the baby changing room either from a spray head arranged centrally in the reel or from a U-shaped water pipe with spray nozzles that surrounds the reel. In both cases between the spray nozzles and the wire to be sprayed, there are pins of the winding space boundaries, the wire that has run in over its length at intervals opposite the wire emerging from the spray nozzles Cover spray cones. This means that there must be different structures over the length of the wire result. The aim, however, is to achieve a structure that is uniform over the length of the wire around the wire rod to be able to draw economically without intermediate heating.

To achieve this goal, the spray nozzles according to the invention are attached to the changing room delimiting pins arranged and the pressurized water brought in via the hollow-drilled pins.

This measure not only removes the "splash shadow" that the pens have with the previously known ones Throw wire reels with radial spray cooling, but the wire is because of the relocation of the spray nozzles in its immediate vicinity also with the maximum outflow velocity of the water particles applied so that no steam bubbles can hold on the wire, which also have a Could cover part of the wire surface. The invention also opens up the possibility of using the wire and spraying the collar from the inside and outside at the same time.

Regarding the state of the art, it should be said that it is for a reel with a circumferential, perforated wall existing winding drum is known, the wire directly from the inner wall with her To act on water that escapes through the spray nozzle openings under the action of centrifugal force. Since water-hardened wire is to be produced with this reel, this is also the long one Practiced water bath cooling. The direct application of the wire results from expedient the special design of the reel with trough-like winding drum. On the further development of reels with rows of pins to limit the winding space, the well-known reel did not have a beneficial effect, especially since -the tendency from the water bath cooling with a sharp quenching of the wire to one Wire reel with water cooling

¹ S more differentiated heat treatment, through which a martensitic structure is avoided in the wire, which is undesirable when drawing the wire.

It is also known to use the pins of a reel for guiding water, but also in connection with a water bath cooling system and for guiding the water back through overflow into the hollow pins. Here, too, there is no problem of avoiding irregularities in the structure of the wire over its length. In addition, the key feature of the invention is not the way the water is brought in via hollow pins, but the arrangement of the spray nozzles on the pins.
The wire is also sprayed in the so-called cooling sections upstream of the reel. At high end speeds of the rolling mill, this cooling is only effective if the cooling section is made very long, which is at the expense of the space required by the system. Problems can also arise when reeling if the wire has already cooled down and is thus stiffened when it shoots into the reel.

Depending on the type of nozzles used, the winding material can be cooled gently or abruptly set so that the manufacture of water wire with the device according to the invention is not excluded is. Here you will spray less to create a water mist than with a large one Squirt secondary amount of water, as is known from the known reel with trough-like winding drum is. In addition, the intensity of the cooling can be controlled by a pump or throttle control of the respective Steel grade can be adapted in a manner known per se.

For using the innovation on an Edenborn reel with a fixed winding basket the water flow to the pens is not difficult

rig. With a Garrett reel, however, certain precautions must be taken, which are explained in more detail in the description of the drawing. In the drawing, a Garrett wire reel with pressurized water cooling according to the innovation is shown as an exemplary embodiment, namely FIG. 1 shows a vertical section through the upper part of a reel with two rows of pins, FIG. 2 shows a plan view of the changing basket and FIG. 3 shows an enlarged partial section according to FIG. 1. The per se known structure of the wire reel comprises a winding plate 1 with two concentric rows of pins or pins 2, 3, a bearing 4 for the hollow shaft 5 rotatably connected to the winding part and a winding plate 6, which over the rod 7 for lifting a wound federal from the pot surrounding the winding basket 8 can be raised and lowered. According to the innovation, the pins 2, 3 are drilled hollow and provided with several superimposed spray or spray nozzles 10 (FIG. 3), to which the pressurized water via the bores 2 a, 3 α in the pins 2, 3 from radially extending pipelines 11 , which rotate with the winding plate 1, is supplied. The spray nozzles 10 are arranged at points on the circumference of the pins 2, 3 which do not come into contact with the wire to be wound, as shown in FIG. 2 can be seen. The direction of spraying is expediently opposite to the direction of rotation of the winding plate 1, as can also be seen from FIG. This reduces the absolute exit speed of the spray water so that it is not driven out of the winding space by centrifugal forces. In order to bring the pressurized water to the revolving pins 2, 3, according to the innovation, an annular distributor piece 12 running around the winding part is provided, from which the radial pipes 11 run to the bores 2 a, 3 a in the pins 2, 3. In the exemplary embodiment, the distributor piece 12 is uniform with the hollow shaft 5 and has a downwardly directed outer collar 12 a and, at a distance therefrom, a rotational surface 12 b. A fixed connection piece 13, which is fastened on the flange ring 14 for the bearing 4, works together with the rotating distributor piece 12. This connecting piece 13 has an upwardly directed collar 13 a, which fits like a piston into the cylinder formed by the collar 12 a of the manifold 12 and, together with the rotational surface 12 b of the manifold 12, forms radial boundary surfaces of an approximately rectangular annular space 15. The pressurized water supplied by a pressure pump 16 is introduced into this annular space 15 via an inlet line 17 by connecting it to the stationary connection piece 13. Since the upper part of the annular space 15 only extends into the circumferential distributor piece 12, the water can be conducted via radial bores 18 from the annular space to the radially extending distributor lines 11. The annular space 15 is sealed on the one hand by a piston seal 19 between the piston-like collar 13 a of the connecting piece 13 and the cylinder-like collar 12 a of the distributor piece 12 and on the other hand by an internal labyrinth-like seal between the two parts 12 and 13. Leakage water that escapes through the labyrinth seal is diverted through holes 21,22 in the connector, namely through openings 8 α in the bottom of the pot 8 and a drain plate 23 covering the entire drive below (Fig. 1). A throttle valve 24 in the feed line 17 can be used to control the incoming amount of pressurized water and thus the intensity of the cooling of the wire. A pressure relief valve 25 works together with the throttle valve 24 and diverts excess water into the container 26. With the pressurized water cooling according to the innovation, you can not only influence the intensity of the cooling by adjusting the manually operated throttle valve 24, but also control the beginning and the end of the cooling process at any time by switching the pump 16. With a regulating pump 16 one could also increase the amount of pressurized water exiting with the growth of the federal government. Patent claims: 1.
