Definitions

  • the invention relates to a device for SZ stranding with the aid of a fixed guide perforated disk and a reversing driven stranding disk, the stranding elements being arranged along a tubular guide and storage body (tubular spider) of the stranding disk arranged concentrically to the stranding axis and extending from the perforated guide disk to the stranding disk are fed.
  • a tubular guide and storage body tubular spider
  • SZ stranding devices in which the processes and the fume cupboards are firmly in the room, are becoming increasingly important in cable manufacturing technology for a number of reasons.
  • a device for SZ stranding as described in DE-PS 682 267, is still proving itself today.
  • the machine known from this publication which is also referred to as a tube storage stranding machine, works with a reversing driven stranding disk, to which the stranding elements are fed via a tube store.
  • the individual elements When stranding with a tube storage machine of this type, the individual elements are partially applied in a spiral shape to the outer surface of the tube storage unit and are pulled off from there again with the aid of a trigger.
  • the lowest possible coefficient of friction is aimed for in order to keep the tensile stress on the stranding elements low.
  • the tube storage SZ method it is customary to design the tube storage in front of the alternating rotating stranding disk either non-rotatable or freely rotatable or to rotate it around the longitudinal axis at the speed of the stranding disk (DE-OS 24 11 151).
  • the tube store is left stationary or driven at the speed of the stranding disk, so that no uncontrolled relative movements of the stranding elements with respect to the tube store result under the influence of inertia and frictional forces.
  • the tube store usually has a considerable mass, which makes it difficult to change direction, for example, in the case of rigid coupling with the stranding disk.
  • this change of direction must be carried out quickly in order to make the swirl change points as short as possible.
  • the invention has for its object to reduce the aforementioned difficulties.
  • the drive for stranding disk and tube accumulator is designed in such a way that the tube accumulator can be driven at a speed which differs from the rotational speed of the stranding disc.
  • the stranding elements when they have laid themselves around the tube storage, exert a "dignity effect" on this body and thus increase the friction even more.
  • the speed of the tube storage device which differs from the speed of the stranding disk, can be effected in different ways.
  • a gear can be arranged between the drive for the stranding disk and the tubular accumulator and this gear can optionally be configured in several stages or as an adjusting gear. But you can also assign your own drive to the pipe storage.
  • a tube store driven at approximately half the speed has the advantage that at both ends of the tube store the stranded material only has half the speed difference compared to the tube store and in the middle of the store the speed of the stranded material and the tube store even match.
  • the arrangement of the guide perforated disk rigidly connected to the tube store need only be arranged approximately in its center and can deviate from this central position by approximately + 20% depending on the size of the speed of the tube store.
  • the tubular storage device which is provided with a guide perforated disk firmly connected to it in the middle, is preferably stored in the area of this perforated guide disk in a fixed frame.
  • the drive for the pipe storage can also be advantageously arranged in the area of the bearing block.
  • the device for SZ stranding consists of a stranding disk 10 which is driven in a reversing manner by the drive 11 and of a tube store 20 which extends approximately between the stranding disk 10 and a perforated guide disk 15.
  • the tubular accumulator is driven by the drive 11 of the stranding disk with the interposition of a gear 23, which can be designed as a stepped or variable gear.
  • the stranding elements 8 belonging to the core layer are guided through the tube store, while the stranding elements 9 to be newly applied are fed from the guide perforated disk 15 along the outer surface of the tube store 20 to the stranding disk 10.
  • the direction of manufacture is indicated by arrow 12.
  • the device for SZ stranding consists of a stranding disk 10 which is driven in a reversing manner by the drive 11 and of a tube store 20 which extends from the stranding disk 10 to a fixed guide perforated disk 15.
  • a separate drive 21 is assigned to the tube store.
  • the low-mass stranding disk 10 can thus be reversed very quickly by its own drive, while the tube accumulator with a large mass has a much more robust drive that does not need to be reversed with the same speed.
  • the core layer 8 is guided through the tube storage device, while the stranding elements 9 (only one element shown) belonging to the layer to be newly applied are fed through the guide perforated disk 15 along the outer surface to the tube storage device 20 of the stranding disk 10.
  • Fig. 3 shows a tubular storage SZ stranding device with the corresponding structure in Figures 1 and 2 from stranding disk 10, tubular storage 20 and guide perforated disk 15.
  • the drives are not shown. It is assumed that the stranding disk 10 is operated at a speed n 1 , while the tubular accumulator is operated at a different speed n 2 , which is approximately equal to 1/2 n 1 . These speed ratios result in a particularly uniform distribution of the wraps of the stranding elements 9 over the entire length of the tube store.
  • a guide perforated disk 25 is rigidly connected to it. This guide perforated disk ensures that the number of wraps in front of or behind the perforated disk of the stranding elements 9 per unit length of the tube store are the same.
  • the area of the tube store 20 with the perforated guide disk 25 is shown enlarged in a detailed representation of FIG. 3.
  • the tube store 20 is mounted on the guide disk 25 by means of the bearings 26 and the bearing block 27. In this area, the separate drive 21 for the tube store 20 is also provided.
  • the tube storage SZ stranding machine shown in Fig. 5 (stranding elements not shown for the sake of clarity) consists in the usual way of a stranding disk 10 which is reversibly operated by a drive 11, a tube storage 20 provided with a separate drive 21 and a guide perforated disk 15 fixed guide hole disc 15 and with the rotating with a different from the tube storage speed stranding sleeve 10 are fixed sleeves 18 and 13, the tube storage over part of its length grab and thus form different speed ranges of the pipe storage.
  • the sleeve connected to the guide perforated disk 15 forms a tubular storage section 51 with zero speed, which is followed by a section 52 with the rotating speed of the tubular storage device 20. This is followed by a further section 53, which has the rotational speed of the stranding disk.
  • the ratios can be changed slightly, for example the sleeve 18 can be made so long that it overlaps almost half of the tube store 20, so that half the length of the tube store has zero speed.
  • the subsequent area of the tube store will be operated at perhaps 75% of the speed of the stranding disk 10. In any case, particularly uniform wrapping of the stranding elements along the entire tube store is achieved with such devices.
