Definitions
- the present invention relates to a method and a device for manufacturing a bead wire embedded in a bead portion of a tire of an automobile, a motorcycle, a field aircraft, or the like to increase a joining force between the tire and a wheel.
- a bead wire that fits into a bead portion of a predetermined wheel and that is attached to a bead portion of the tire to tighten the wheel in a circumferential direction and improve a joining force between the wheel and the tire is provided.
- This bead wire can exert an effect of suppressing deformation of a tire at the time of cornering or the like and increasing running stability in an automobile, for example. For this reason, there is a demand for a material that can exhibit a stable and high joining force due to the increase in weight due to the recent increase in the size of vehicles and the improvement in vehicle speed due to maintenance of expressways and the like.

- the steel wire is wound around the annular core while twisting the cross section of the steel wire so as to always contact the steel core. Therefore, in order to wind the steel wire, a large torsional force equal to or more than the torsional yield stress of the steel wire and a large bending force equal to or more than the bending yield stress of the steel wire are required. Then, such torsion force and bending force are accumulated as residual stress in the steel wire, and the residual stress acts to repel the state wound around the annular cored bar.

Without generating a force that repels the ring. Since it can be integrated very naturally so as to follow the metal core 2, the desired twisted bead wire 1 can be easily and appropriately manufactured.
- the stranded bead wire 1 manufactured in this manner is embedded in an automobile tire to enhance the bondability between the tire and the wheel, exhibiting excellent running stability and high strength and durability. Will do. Therefore, as described above, it is extremely difficult to wind the conventional steel wire 3, and the problem that a twisted bead wire capable of sufficiently exhibiting desired performance cannot be manufactured is solved. This can be solved by the present invention.
- the idler reel 23 around which the steel wire 3 is wound is arranged so as to be idle, and can be wound around the rotating annular core 2.
- the idle reel 23 is urged in a direction opposite to the rotation direction in which the steel wire 3 is wound, and tension is applied to the steel wire 3.
- the first embodiment there is a configuration in which an electromagnetic stone is arranged on the upper surface of the movable support base 24, and a resistance force is applied to the rotation of the idle reel 23 by this electromagnet. By applying the tension in this manner, the steel wire 3 is always wound up at a constant rate, so that a twisted wire wire with even better integration between the annular cored bar 2 and the steel wire 3 is manufactured. be able to.

- the guide rails 25, 25 of the third embodiment and the guide rails 50, 50 of the fourth embodiment can be replaced with arc-shaped guide rails.
- the core metal guide rail 74 can be changed to a shape that curves upward.
- arc-shaped guide rails 34 and 34 similar to the second embodiment described above are provided.
- the movable support table 40 for rotatably supporting the idle reel 23 is moved by the movable rod 4 1 into and out of the guide rail 3 4. , 3 4 to repeatedly move between support position A and support position B You.
- the lifting rollers 27 and 27 are moved up and down one time, and the idle reel 23 is repeatedly moved above and below the annular core 2.
- the pseudo-linear repetitive movement to be repeated is repeated.
- a desired twisted bead wire 1 similar to that of the third embodiment can be manufactured. Further, similarly to Embodiment 2 described above, during the repetitive movement of the idler reel 23, the length of the steel wire 3 wound on the annular core 2 from the idler reel 23 becomes substantially constant. However, the steel wire 3 is less likely to be loosened, and the integrity of the annular core metal 2 and the steel wire 3 can be further improved.
- the manufacturing apparatus 14 of the above-described fifth embodiment has a configuration in which the annular cored bar 2 is rotated substantially in the vertical direction in the circumferential direction.
- the annular core 2 is rotated in the circumferential direction in a substantially horizontal shape.
- the reel conversion device 72 changes the position of the idle rotation reel 23 substantially in the vertical direction.
- the rotating surface of the annular cored bar 2 can be set to be appropriately inclined according to the installation environment and the like.
- the position of the metal core moving base 73 that supports the annular metal core 2 is fixed, and the magnet support column 76 and the magnet moving device 80 are synchronized with each other, thereby It is also possible to adopt a configuration in which the metal core 2 is moved in and out of the annular core metal 2 along the plane f crossing the metal core 2. This is because, with respect to the annular core 2 rotating in the circumferential direction at the fixed position, the idle reel 23 is attached to the outer side of the annular core 2 on one side of the surface f crossing the annular core 2.
- each movement of the magnet support column 76 and the magnet mover 80 is performed by providing a guide rail, a drive cylinder, and the like, respectively. Even in such a configuration, a desired twisted bead wire 1 can be manufactured as in the fifth embodiment.
- the reel conversion device 72 configured to convert the idle rotation reel 23 to both surfaces of the annular core metal 2 by using an electromagnet and a magnetic material is provided. In addition to electromagnets and magnetic materials, it is also possible to use suction cups, air chucks and the like.
- the core metal elevating device 21, the reel moving devices 22 and 42, the seesaw moving device 52, the core metal moving device 71, and the reel converting device 72 are used.
- a hydraulic or pneumatic cylinder or the like is used as a driving device, a cam, a crank, a stepping motor, or the like can be used as a driving device instead of the cylinder.
- the steel wire 3 was temporarily fixed to the annular metal core 2, but the steel wire 3 was wound a few times in advance so as not to twist the cross section.
- the control operation of each manufacturing apparatus may be started.
- the tip and the end may be fixed around the bead wire.
- a device for temporarily fixing the steel wire 3 or a device for connecting the tip and the end may be provided to further improve the working efficiency.
- the twisted bead wire 1 having the same form is manufactured.
- other forms of the bead wire can be manufactured in the same manner. it can.
- the number of laps to be aligned can also be set variously.
- the steel wires 3 can be formed by being entangled so as to be laminated plural times. The form of such a bead wire is appropriately set according to the application.
- the present invention is not limited to the above embodiments, but can be implemented in various forms without departing from the gist of the present invention.
- the twisted bead wire 1 to be embedded in an automobile tire was manufactured.
- the above-described configuration has been exemplified, it is also possible to provide a manufacturing apparatus for manufacturing a twisted bead wire for a tire such as a pike or an aircraft with a similar configuration.
- the method for producing a twisted beader comprises: rotating a circular cored bar in a circumferential direction; and winding a steel wire bundle formed by winding a steel wire to a smaller diameter than the circular cored bar.
