Method and apparatus for the continuous production of

Wire rope

The invention relates to a method and a device for continuously producing a twisted wire rope from a plurality of strands.

It is known to produce a twisted wire rope, using as many wires as the starting material the wire rope should have strands and the wires should be wound up are wound up. The wires run through a guide or a so-called perforated disk or drawing iron with a number of grooves or drawing holes corresponding to the number of wire strands which the wires are guided individually, presented to a nipple and united therein. The wire strands are then twisted by a relative rotational movement between the discharged wire rope and the perforated disc. This Helativdreb movement is through either Rotation of all the wire reels and the perforated disc that feed the starting material, or it is produced by rotating the winding drum onto which the finished wire rope is wound.

grand of both the raw material feed rollers and the large drum wound with the finished wire rope Mass must keep the speed of these devices low so that the latter is not stressed too much during rotation will. The speed thus limits the manufacturing speed in a decisive manner for the wire rope and therefore such a method is relatively expensive, since it is per unit of time only a short length of wire rope can be produced. In addition to the low production speed, this method still has the disadvantage that it has to be interrupted each time a Wire roll has run empty so that a full wire roll is attached and the new wire end can be spliced to that of the previous boll. Of course, production has to be stopped and the costs are additionally increased. Since a variety of reels of wire are usually used and these If possible, they should not be replaced at the same time, because otherwise the strength of the rope due to weak splices would suffer, many such machine downtimes have to be accepted.

The aim of the invention is to overcome the disadvantages of the known methods turn off. This is achieved according to the features of the method and the device described in the claims Invention causes.

Other advantages; Details and features of the invention emerge from the following description. On the drawing is the invention shown for example, namely show

With the device according to the invention according to FIG a continuous production of a twisted wire rope is possible. From a stationary wire feed 10 wire 13 is continuously withdrawn via guide rollers 11, 12, which is first between two superposed rollers 14, 15 passes through, between where the wire is rolled into a strip 16 wide. The tape 16 then runs through one of the rollers 14, 15 directly downstream- ' te scissors or cutting device 17, 18, in which it is divided into as many strands 19 as the finished drill rope should have. The scissors arrangement can be of any known type, e.g. as described in SW-IS 76 361, which relates to a method for the production of wire from a strip or sheet in a single operation. The various strands 19 that are already are brought into the desired shape in the cutting device 17, 18 are then through a one hole per Perforated disc 20 having stranded wire and then guided to a nipple 21, in which they are united. The finished wire rope 22 then runs between a pair for shaping and / or guiding Rolls 23, 24 through and is wound up on a take-up drum 25. To achieve the twist, either the run-up must: drum 25 on which the finished wire rope is wound, and the Rollers 23, 24 are rotated with respect to the perforated disk 20, or but the unit, consisting of the rollers 14, 15, the cutting device 17, 18 and the perforated disc 20, in relation to the overrun drum 25. The ability to keep the cylinder 25 stationary and instead the rollers, the cutting device and the To set the perforated disk in rotation is given by using a single wire 13 as the starting material for the wire rope is, whereby the rotation between the fixed Drahtzufüh-. tion 10 with the guide rollers 11, 12 and the rollers 14, 15 through. Torsion in the wire is achieved. So it doesn't do this this way: necessary to rotate the entire output wire feed roller so

3098Ü9 / 0776

that the mass to be set in rotation is reduced, but only the rollers, the cutting device and the perforated disc need to be set in rotation. Overall, the problems occurring in twisting are essentially the same as before, but the method according to the invention offers the great advantage that the wire feed 10 can be continuously supplemented, since it is stationary, namely by welding of a new wire to the end of an expired wire roll without having to interrupt the process. Since the Splice point is then rolled by the rollers 14, 15, every weak point in the finished wire rope is largely eliminated because a number of wire strands are connected to one another almost simultaneously. The rollers 14, 15 and the Cutting devices 17, 18 are provided with a device 26, 27 or 28, 29 for their respective drive. The main method of manufacturing wire ropes described above according to the invention, that is, the use of a single wire as the starting material, the rolling of this wire into a strip that Cutting the tethered tape into a multitude of strands and that Twisting the different strands to form a wire rope offers a great advantage over the known methods because the manufacturing process can take place continuously and thus results in higher production and is cheaper.

The method according to Fig. 1 has the additional advantage that through a further development, a substantial reduction in the masses to be set in rotation is possible. Fig. 2 shows an example of a further development of the method shown in Fig. 1, wherein the rollers 14, 15, the cutting device 17 · and the perforated disk 20 are introduced into a stationary fork carrier 26 and consequently do not take part in the rotation. Instead, only one loop of the supplied wire 13 and j a loop of the wire rope 22 together with certain brackets!

gen twisted for these loops, whereby the total mass to be set in rotation can be largely reduced, so that; the speed can be kept lower and, in turn, a higher production speed can be achieved. _;

The embodiment of the device according to FIG. 2 comprises a first and a second shaft 27, 28 which are arranged coaxially to one another and between which the fork carriage 26 is mounted in such a way that the shafts can rotate without it: turns himself. The rollers 14, 15, the cutting device 17, 18 and the perforated disk 20 are accommodated in the fork carriage 26. As a result, the perforated disc 20 is stationary and the nipple 21 is rotatable. The nipple 21 comprising the strands 19 is expediently in or on the shaft carrying the fork carriage 26 27 attached. Around the wire 13 in a loop around the fork carriage 26 around, a first and a second roller 29, 30 are provided on the first shaft 27, which participate in the rotation of the shaft and of which the second roller 30 is further away from the The center line of the shaft 27 lies as the first roller 29. The second shaft 28 is provided with a third and a fourth roller 31, 32 for the wire loops, which are arranged accordingly, participate in the rotation of this shaft and of which the third roller; 31 is further away from the center line of the shaft 28 than the fourth roller 32. In this way, both are on the first Shaft 27 and on the second shaft 28 rollers 33 to 36 for guiding the wire rope running out of the fork carriage in one Loop provided around this latter. Through these roles; 29 to 36 are consequently a wire loop as well as a wire; Rope loop is guided around one half of the circuit and at a distance from the fork carriage around this; this allows at the same time the loops and the rollers are set in rotation around the fork carriage and the devices therein. '

309809/0776

The shafts 27, 28 are provided at their two ends with axially extending central channels 37, 38 and 39, 40 which are bent at a certain distance from the ends and open onto the cylindrical surfaces of the shafts.

As shown in FIG. 2, the fed wire 13 runs away from the feed towards the channel 37 at the section lying in the region of the feed of the first shafts 27 and then runs axially through this section to the first roll 29, where the wire leaves the shaft 27 and runs around the second roll 30 of the first shaft and from there on to the third roll 31 of the second Shaft 28 and then inward to the fourth roller 32, then into the channel 39 in the section of the second shaft 28 located next to the fork carriage 26 and axially into the fork carriage, runs there between the rollers 14, 15 and then through the cutting device 17, 18, in which the various Strands 19 are formed. The individual strands 19 run through the various holes in the perforated disk 20 to the nipple 21, in which they are united and thence out in the form of one Wire rope out of the fork carriage and into the channel 38 in the section of the first shaft 27 located next to the fork carriage. The wire rope 22 is guided around the first pulley 33 of the wire rope loop and away from the shaft 27 around the second pulley 34, which is also assigned to the first shaft 27, and on to the third pulley 35 of the second shaft 28, up to the fourth is also located on the second shaft 28 roller 36 and via this in the channel 40 of the shaft and axially through its from Fork carriage distant section, away from the shaft and on to the wire rope take-up drum.

During the production of the wire rope as described, the wire loops and the wire rope loop are rotating around the stationary fork carriage offset, the torsion formed before the introduction of the wire into the fork carriage by rotation xuj

309809/0776

Wire picked up and when leaving the strands out of the nipple is used to twist the same. The wire turn results on the one hand "when inserting the wire into the rotating loop and on the other hand when inserting the wire into the stationary loop Fork carriage. The twisting of the strands of the wire rope finaet on the one hand when inserting the wire rope into the rotating one ürahtseilschleife and on the other hand when inserting the wire rope in the stationary collecting drum. In both cases the rotation in the wire loop is in the same direction and twisting of the wire rope in the same way in both cases Direction executed. The direction of rotation of wire loop and Wire rope loop, on the other hand, is the opposite.

The embodiment according to FIG. 2 consequently has the large one The advantage that only very small masses have to be set in rotation, which are in any case considerably smaller than before is the case, so that a higher production speed is achievable. If the finished wire rope has a certain number of turns per unit of length, the production speed can obviously proportional to the number of turns increased v / earth. Mt of the device according to FIG. 2 is twice the speed achievable because the twisting takes place at two points, namely both when entering and when exiting the itself rotating loop.

Of course, the invention are within the scope Abwandlun- ¹ gen possible. So the roles can be guided by other guides, for example ^! be replaced by curved tubes, and the loops need; not be arranged diametrically to one another, although a diametrical arrangement is advantageous because of the: balance. The \ rollers for the finished rope is expedient if the strands get a square cross section at the 'cutting. When the strands; but already when cutting with an essentially round; Are provided cross-section, this operation can be omitted.

309809/0776

Of course, other rolling devices can also be provided for rolling the wire, e.g. a duo rolling mill or a so-called. Inner rolling mill. Devices other than rollers can also be used to flatten the wire. In order to these rolling mills can roll out the starting wire to the maximum width, it may be necessary, for example, to use an additional rolling or; Cutting operation because narrow strips can be rolled out to a higher percentage than wide strips. Furthermore, several oppositely rotatable wire and wire rope loops can be provided within the scope of the invention, whereby the j Rotation speed can be increased by two, four, six times, etc. of the original value. :

. Since twisted wire ropes can be produced continuously with the device according to the invention, they can easily be turned into an! installed position, e.g. a wire drawing machine or the like. downstream whereby the wire feed can be reduced or completely switched off. It can also be a Plastic coating machine are arranged so that an insulated wire rope can be achieved. This process offers the possibility of extensive rationalization because there is no need for intermediate storage.

The method according to the invention is suitable for all drawable metals within a wide range of dimensions, e.g. a solid wire from 1.5 to 1t? mm diameter on the inlet side, However, the range of dimensions depends only on the type of machine from and consequently large deviations from the range given above, only as an example, are possible.
