Definitions

  • the present invention relates to rope manufacturing methods and to the construction of rope making machines.
  • a rope production method is widely known in which the round wires unwound from the coils are given a helical permanent deformation before they are wound onto the core.
  • each wire is informed of a progressive and a rotary movement about its geometric axis, whereupon the wire is bent on supports arranged one behind the other.
  • the deformed wires are wound onto the core, compressed, pulled, and a rope is wound on a drum.
  • a rope making machine that implements the method described above is also well known.
  • This machine contains one behind the other - a drum with a core wound on it; a rotor with coils, which is arranged on a hollow shaft through which the core passes; a housing which is arranged at the output part of the hollow shaft and is coaxial with it and carries the supports which are wrapped around the wires; a nozzle in which the deformed wires are wound onto the core and compressed; a pull-out device and a customer drum for rope tying.
  • each wire is simultaneously informed about an axis rotation and a continuous movement with subsequent bending on the supports.
  • each coil is arranged in the pivot bearings of a frame.
  • the frame is fixed in the rotor on its own swivel bearings.
  • the axis of rotation of the frame is perpendicular to the axis of rotation of the coil. All frames are kinematically connected to a drive for their rotation around their bearings (see for example SU-A1-1152 986 or SU-A1-703 613).
  • the rope manufacturing machine performing the well-known method described above is structurally complicated due to the arrangement of the spools in the forcibly rotating frame. This leads to an increase in the dimensions and mass of the rotor, which in turn limits its speed and the machine performance as a whole. In addition, such a machine requires a considerable amount of energy.
  • a rope manufacturing process is known in which the helical permanent deformation is imparted to each wire as follows: each wire is bent as it progresses from the spool into a loop that is rotated about the wire axis, causing the wire to plastically twist at the entrance to it the loop is imparted a required axis rotation at the exit from the loop; Furthermore, the wire is bent on supports (see SU copyright certificate 859513) as it moves and rotates about its geometric axis. The procedure is otherwise similar to that described above.
  • a rope making machine which, arranged in series, contains: a drum with a core wound thereon; a rotor with coils attached to it and arranged on a hollow shaft through which the core passes; a device for permanent deformation of wires, which is fastened to the output part of the hollow shaft and coaxial therewith; a drawing nozzle in which the deformed wires are wound onto the core and compressed; a pull-out device and a take-off drum for the rope.
  • the device for permanent deformation of wires has a housing with hollow shafts arranged on its circumference, the number of which corresponds to that of the wires to be struck, and supports for the bending of each wire.
  • the hollow shafts are kinematically connected to a drive for their rotation.
  • the entrance part each hollow shaft has a fork, in which a roller is freely rotatable on an axis offset with respect to the hollow shaft axis. This role serves to bend the moving wire, which then passes through the central bore of the hollow shaft.
  • each wire In order to impart an axis rotation to the wire, it is bent like a loop on a roll. In order to achieve the required accuracy of the helical permanent deformation, each wire is bent like a loop with the greatest possible degree of elastic deformation. This is achieved with relatively large dimensions of the roll on which the wire is bent in a loop.
  • the large dimensions of the rollers enlarge that of the housing on which these rollers and the hollow shafts are arranged, which makes the drive for the rotation of the hollow shafts and the construction of the device as a whole more complicated.
  • the large dimensions of the device for helical permanent deformation of wires accordingly increase the mass of the rotating parts of the rotor of the cable manufacturing machine. This limits the speed of the rotor and the overall performance of the rope making machine. In addition, such a construction of the rope-making machine also requires an increased expenditure of energy.
  • the invention has for its object to provide such a rope manufacturing method and such a rope manufacturing machine, in which the permanent deformation of the wires is achieved with simpler means, which makes it possible to simplify the construction of the rope manufacturing machine, to reduce the mass of the rotating parts of the rotor and so to increase the machine performance.
  • a rope manufacturing machine which, arranged one behind the other, has a drum with a core wound on it; a rotor with attached coils having a wire, which is arranged on a hollow shaft through which the core passes; a device for permanent deformation of wires arranged at the output part of the hollow shaft and coaxial with this; a drawing nozzle in which the deformed wires are wound onto the core and compressed; contains a pull-out device and a take-up drum for the rope, in which the invention the device for permanent deformation of wires has a housing on which two supports are arranged one behind the other for each wire, the first freely rotatable about its geometric axis and the second about its geometric Axis are freely rotatable and rotatably fastened about an axis perpendicular to the geometric axis of the second support.
  • the machine according to the invention has a relatively simple construction, a smaller rotor mass thanks to the smaller mass of the device for the helical permanent deformation of wires.
  • first support prefferably has a plurality of grooves and for the second to have an elongated cylindrical surface which is sufficient for the arrangement of wire spirals to be bent on the first support.
  • the rope manufacturing process and the rope manufacturing machine performing this ensure, with a relatively simple design, a considerable increase in machine performance while improving the quality of the ropes to be laid and using less energy.
  • each wire 2 progressively coming from a coil 1 (FIG. 1) is given a flat bend with a permanent deformation on a support 3 by being wrapped around it at an angle of 360 ° and a subsequent bend in one direction. which is pivoted with respect to the original flat bend.
  • the subsequent bending takes place on a support 4 by spiral winding of the wire.
  • the wires 2 are wound with the resulting helical permanent deformation on a core 5 in a drawing nozzle 6.
  • 2 shows the implementation of the flat bending of the wire 2 on two supports 3a and 3b.
