Description

  The present invention relates to a processing apparatus for a coiled metal wire (in particular, a coiled steel wire). The treatment apparatus according to the present invention is, for example, in a state where a steel wire wound in a coil shape is suspended from a C-shaped hook and suspended, and is successively conveyed to various immersion baths by a traveling hoist for surface treatment. In particular, when immersed in a pickling bath, it can be effectively used in a technique in which vibration is applied by a vibrating body in a suspended state suspended by a C-shaped hook, and the coiled steel wire is vibrated and pickled.

When pickling this type of coiled steel wire rod, the steel wire rod is suspended in a C-shaped hook and immersed in a washing tank, and the C-shaped hook is subjected to pickling by applying vertical vibration. . This is because the coiled steel wire is wound in a spiral shape and the adjacent surfaces of the steel wire are in contact with each other, so that the adjacent contact surface does not come into contact with the treatment liquid simply by dipping. . That is, by applying vertical movement vibration to the C-shaped hook, the treatment liquid is infiltrated between the spiral contact surfaces, and the entire surface of the steel wire is efficiently brought into contact with the treatment liquid.
However, when picking up by applying vertical vibration to the C-shaped hook, the contact surface between the coiled steel wire and the C-shaped hook is in vertical contact, so that the vertical vibration is applied to the C-shaped hook. Even if given, it is difficult to effectively infiltrate the treatment liquid.

Various methods for exposing the surface of the coiled steel wire in contact with the carrying surface of the C-shaped hook to contact the treatment liquid have been proposed. For example, the bottom of the bathtub is inclined, and at first, in the state where the bottom of the coiled steel wire does not contact the inclined surface of the bottom of the bathtub, vibrations are applied to the C-shaped hooks to treat adjacent surfaces of the steel wires. After that, stop the vibration. Subsequently, when the C-shaped hook is lowered and the bottom of the coiled steel wire is brought into contact with the inclined surface of the bottom of the bathtub, the coiled steel wire rolls against the C-shaped hook and comes into contact with the surface of the C-shaped hook. The surface of the coiled steel wire that has been moved moves relative to the C-shaped hook and is exposed. In this state, a method has been proposed in which the C-shaped hook is lifted upward and the vertical vibration is again applied to the C-shaped hook (Patent Document 1).
However, in this method, it is necessary to interrupt the vibration processing and raise and lower the C-shaped hook to expose the contact surface, which is not satisfactory in terms of processing time. Moreover, it was necessary to provide an inclined surface at the bottom of the bathtub.

Also, reversing means is provided at the bottom of the bathtub, and at first, in the state where the bottom of the coiled steel wire does not contact the reversing means of the bottom of the bathtub, the C-shaped hook is subjected to vertical motion vibration and adjacent to each other. After the surface is treated and vibration is stopped, the C-shaped hook is lowered and the bottom of the coiled steel wire is brought into contact with the reversing means at the bottom of the bathtub. The surface of the coiled steel wire that has been in contact with the surface of the C-shaped hook moves and is exposed to the C-shaped hook. In this state, a method has also been proposed in which the C-shaped hook is lifted upward and the vertical vibration is applied to the C-shaped hook again (Patent Document 2).
However, even with this method, it is necessary to interrupt the vibration processing and move the C-shaped hook up and down to expose the contact surface, which is not satisfactory in terms of processing time. Moreover, it was necessary to provide a reversing means at the bottom of the bathtub.

  Furthermore, a method of providing a vibrator on a base plate that suspends and holds the C-shaped hook and a method of providing a vibrator on the suspension shaft of the C-shaped hook have been proposed (Patent Document 3). In the method of providing a vibration exciter on the base plate holding the C-shaped hook, by providing the vibration exciter so that the vibration acting line of the vibration exciter is in a vertical direction shifted from the gravity line of the coiled steel wire, It is said that not only the coiled steel wire is subjected to vertical vibration, but the coiled steel wire can be rotated at the same time. Moreover, in the method of providing a vibrator on the suspension shaft of the C-shaped hook, the vibrator is vibrated obliquely in the vertical direction, whereby not only the coiled steel wire is vibrated in the vertical direction, but also the coil shape. It is said that the steel wire can be rotated.

  In this method, it is necessary to provide a vibrator for every C-shaped hook. However, some treatment baths for coiled steel wires do not need to be vibrated, which is not preferable in terms of cost. . Furthermore, when changing the type of coiled steel wire to be processed, it is necessary to change the vibration conditions by the vibrator, but it is necessary to adjust the vibration conditions for all the individual vibrators. It was cumbersome. In addition, there are various treatment baths, such as a bath that is exposed to acid vapor, such as a pickling bath, or a bath that is simply exposed to water vapor. Cover means for protecting the vibrator is required, which is not preferable in terms of cost. When there are baths that require different vibration conditions, it is necessary to control the vibration conditions for each of the baths, which is complicated.

  Accordingly, an object of the present invention is to provide a surface treatment by transferring a metal wire material such as a coiled steel wire material to various immersion baths one after another by a traveling hoist in a state where the metal wire material is suspended from a C-shaped hook and suspended. An object of the present invention is to provide a new means that eliminates the above-mentioned drawbacks of the prior art when rotating a coiled steel wire while giving vertical vibration to the shaped hook.

The above problems are solved by the present invention.

A coil-shaped metal wire suspension device including a C-shaped hook portion that is fixed to the suspension beam portion and can suspend the coil-shaped metal wire material, and (d) a hanging portion provided on the suspension beam portion. A coiled metal wire processing apparatus capable of immersing a coiled metal wire suspended from a C-shaped hook portion in a treatment liquid in an immersion treatment bath while being detached from the traveling hoist and held detachably. And

(4) A base that supports the excitation unit via the buffer unit,
(5) A deflection part provided in contact with the excitation part, and (6) a vibrating body capable of transmitting vibration to the excitation part via the deviation part. This can be solved by a processing device for a metal wire rod.

  The present invention also immerses the coiled metal wire suspended from the C-shaped hook portion of the coiled metal wire suspension device in the treatment liquid in the immersion treatment bath and simultaneously vibrates the coiled metal wire vertically. The present invention also relates to a method in which the entire surface of the coiled metal wire is brought into contact with a treatment liquid by rotating with respect to a C-shaped hook portion.

According to the apparatus of the present invention, when the coiled metal wire suspended from the C-shaped hook part (particularly, the coiled steel wire) is immersed in the treatment liquid in the immersion treatment bath, the suspension direction of the coiled metal wire ( Since the coiled metal wire is vibrated in a direction obliquely shifted with respect to the vertical direction), the coiled metal wire is not only swung up and down, but at the same time, the coiled metal wire is rotated with respect to the C-shaped hook part. Will do. Therefore, not only can the processing liquid efficiently enter between the spiral adjacent contact surfaces between the coiled metal wires, but the contact surface between the coiled metal wires and the C-shaped hook can be continuously exposed. Can be brought into contact with the treatment liquid. For this reason, in order to process the coil-shaped metal wire surface which contacts a C-shaped hook, it is not necessary to interrupt vibration processing. Moreover, the stable rotational motion can be provided with respect to the coil-shaped metal wire suspended by the C-shaped hook part.
The apparatus of the present invention does not need to provide a vibrating body for each C-shaped hook, and can be provided only in a treatment bath that requires vibration treatment, so that the number of necessary vibrators to be installed is reduced. The apparatus of the present invention can be integrated with the treatment bath as well as the treatment bath. In addition, it is possible not only to set appropriate vibration conditions for each treatment bath, but also to change the vibration conditions for changing the type of coiled metal wire to be treated. Furthermore, it becomes possible to protect the vibrating body corresponding to the difference in the use environment for each treatment bath. In other words, when it is attached to a treatment bath that is exposed to acid vapor, such as a pickling bath, a protective cover that is not affected by the acid vapor is provided, and it is attached to a treatment bath that is simply exposed to water vapor. It can be a simple protective cover.

FIG. 1 shows an immersion treatment bath 6 (a part of a wall surface 61) of a coiled metal wire 5 suspended from a C-shaped hook 33 in a state where a coiled metal wire suspension device 3 is placed on the device 1 of the present invention. It is a typical perspective view which shows the state immersed in the process liquid 7 of notching and showing. A typical example of the coiled metal wire is a coiled steel wire, and a typical example of the immersion treatment bath is a pickling bath.
The coiled metal wire suspension device 3 used together with the device 1 of the present invention includes a rod-shaped suspension beam portion 31, a locking portion 32 (32a, 32b) provided on the suspension beam portion 31, and a lower portion from the suspension beam portion 31. A C-shaped hook portion 33 fixed to the hanging beam portion 31 in a suspended state, and a hanging portion 34 (34a, 34b) provided at both ends of the hanging beam portion 31.

  The locking portions 32a and 32b provided on the upper surface of the hanging beam portion 31 can be detachably attached to a traveling hoist (not shown). FIG. 1 shows a state where a coiled metal wire suspension device 3 is removed from a traveling hoist and placed on the device 1 of the present invention. When the treatment in the immersion treatment bath 6 shown in FIG. 1 is completed, the coiled metal wire suspension device 3 is attached to the traveling hoist by the engaging portions 32a and 32b, and is lifted upward to be moved to another treatment bath. it can.

  The C-shaped hook portion 33 is fixed to the bottom surface of the suspension beam portion 31 by the connecting portion 35, and the steel wire 5 as a coiled metal wire can be suspended from the horizontal bar portion 36. As shown in FIG. 1, with the coiled metal wire suspension device 3 mounted on the device 1 of the present invention, the entire steel wire 5 is completely in the treatment liquid 7 (for example, sulfuric acid aqueous solution) in the immersion treatment bath 6. The liquid level of the treatment liquid 7 is adjusted so as to be immersed.

The device 1 of the present invention includes a vibration unit 11 provided with a placement unit 18, a coil spring 12 as a buffer unit, a base 15 that supports the vibration unit 11, a deflection unit 13, and a vibration body. Vibration motor 14. The present invention device 1 shown in FIG. 1 has a pair of vibration units 1A and 1B, that is,
[1] Excitation unit 1A including an excitation unit 11a provided with a placement unit 18a, a coil spring 12a as a buffer unit, a base 15a, a deflection unit 13a, and a vibration motor 14a as a vibrating body; ,
[2] Excitation unit 1B including an excitation unit 11b provided with a placement unit 18b, a coil spring 12b as a buffer unit, a base 15b, a displacement unit 13b, and a vibration motor 14b as a vibrating body.
Consists of.

  The placement portions 18a and 18b are provided at the center of the upper surface of the plate-like excitation portions 11a and 11b, and the placement portions 34a and 34b can be placed thereon. If necessary, it is possible to have means for fixing the suspended beam portion 31 to the excitation portions 11a and 11b. Excitation parts 11a and 11b are held by bases 15a and 15b via coil springs 12a and 12b. The bases 15a, 15b include a vibration support frame 16 (16a, 16b) and a support 17 (17a, 17b) that supports the vibration support frame 16 (16a, 16b).

  The vibration parts 11a and 11b are provided with vibration motors 14a and 14b on the bottom surfaces via the displacement parts 13a and 13b. In the device 1 of the present invention shown in FIG. 1, a triangular prism displacement portion having a triangular cross section is used as the displacement portion 13, and a vibration motor 14 is attached to the slope of the triangular prism body. The deflection unit 13 has an action of shifting the vibration direction transmitted from the vibration motor 14 to the excitation unit 11 from a parallel direction or a vertical direction with respect to the excitation unit 11. The device 1 of the present invention is shown by an arrow L in FIG. 1 on a coiled steel wire 5 suspended from a C-shaped hook portion 33 by providing a displacement portion 13 between the vibration motor 14 and the vibration portion 11. Thus, the coiled steel wire 5 can be rotated as shown by the arrow R in FIG.

The operation of the deflection portion 13 used in the device 1 of the present invention will be described with reference to FIGS. 2 to 5 (schematic partial enlarged views).
2 and 3 show a case in which the vibration motor 14 is directly attached to the excitation unit 11 without using the deflection unit. As shown in FIG. 2, the vibration motor 14 is arranged so that the rotation axis of the vibration motor 14 is parallel to the bottom surface of the plate-like excitation portion 11 and parallel to the horizontal bar portion 36 of the C-shaped hook portion 33. When the vibration unit 11 is attached, the vibration unit 11 vibrates in the vertical direction with respect to the base 15 as indicated by an arrow V in FIG. Therefore, the suspended beam part 31 placed on the vibration part 11 vibrates in the vertical direction, and only the vertical vibration is given to the coiled steel wire, and it does not rotate. Further, as shown in FIG. 3, the vibration motor 14 is arranged such that the rotation shaft of the vibration motor 14 is parallel to the bottom surface of the plate-like vibration portion 11 and perpendicular to the horizontal bar portion 36 of the C-shaped hook portion 33. Even if 14 is attached to the vibration unit 11, the vibration unit 11 vibrates in the vertical direction with respect to the base 15 as indicated by an arrow V in FIG. 3. Therefore, the suspended beam part 31 placed on the vibration part 11 vibrates in the vertical direction, and only the vertical vibration is given to the coiled steel wire, and it does not rotate.

On the other hand, FIGS. 4 and 5 show a case where the triangular prism deviation portion 13 is provided between the vibration motor 14 and the excitation portion 11.
As shown in FIG. 4, the direction of the rotation axis of the vibration motor 14 is parallel to the inclined surface 13A of the triangular prism deviating portion 13 and is perpendicular to the inclined direction, and the horizontal bar portion 36 of the C-shaped hook portion 33 extends. When the vibration motor 14 is attached to the inclined surface 13A of the triangular prism deviation portion 13 so as to be parallel to the vertical axis, the vibration motor 14 is perpendicular to the inclined surface 13A of the triangular prism displacement portion 13 as shown by an arrow S in FIG. Since vibration is applied in the direction, the excitation unit 11 also vibrates in the same direction. When this vibration is decomposed into vibration components, it consists of a horizontal vibration component indicated by an arrow H and a vertical vibration component indicated by an arrow V with respect to the base 15, and such vibration is given to the excitation unit 11.

Further, as shown in FIG. 5, the direction of the rotation axis of the vibration motor 14 is parallel to the inclined surface 13A of the triangular prism deviating portion 13 and is also parallel to the inclined direction, and the horizontal bar portion 36 of the C-shaped hook portion 33 is Even if the vibration motor 14 is attached to the inclined surface 13A of the triangular prism displacement portion 13 so as to be perpendicular to the extending direction, the vibration motor 14 is applied to the inclined surface 13A of the triangular prism displacement portion 13 as shown by an arrow S in FIG. On the other hand, since the vibration is applied in the vertical direction, the excitation unit 11 also vibrates in the same direction. When this vibration is decomposed into vibration components, it consists of a horizontal vibration component indicated by an arrow H and a vertical vibration component indicated by an arrow V with respect to the base 15, and such vibration is given to the excitation unit 11.
Therefore, in both cases shown in FIG. 4 and FIG. 5, the coiled steel wire suspended from the suspension beam portion 31 placed on the excitation unit 11 is subjected to vertical vibration, and at the same time, coiled. The steel wire rotates.

  The inclination direction of the inclined surface 13A of the triangular prism deviating portion 13 is perpendicular to the direction in which the horizontal bar portion 36 of the C-shaped hook portion 33 extends (that is, the direction of the winding axis of the coiled metal wire). Most preferred. This is because the coiled metal wire can be rotated most efficiently. As long as the direction of the rotation axis of the vibration motor 14 is parallel to the inclined surface 13A of the triangular prism deviating portion 13, the inclined direction of the inclined surface 13A may be vertical (see FIG. 4) or parallel (see FIG. 5). .

  The angle θ (see FIG. 4) between the inclined surface 13A of the triangular prism deviating portion 13 and the bottom surface of the plate-like excitation portion 11 is particularly limited as long as the coiled steel wire can be rotated by a deviation in the vibration direction. Although not performed, 5 ° to 30 ° is preferable, and 10 ° to 20 ° is more preferable. As the vibrating body, for example, a cam mechanism can be used in addition to the vibration motor. As the buffer portion, any spring or air cushion can be used in addition to the coil spring.

A method for treating the surface of a coiled metal wire using the treatment apparatus according to the present invention will be described below.
First, in a state where the steel wire 5 as the coiled metal wire is suspended from the horizontal bar portion 36 of the C-shaped hook 33 provided in the coiled metal wire hanging device 3, the coiled metal is moved by a traveling hoist. The wire suspension device 3 is conveyed above the immersion treatment bath 6. Subsequently, the coiled metal wire suspension device 3 is lowered, and the hanging portions 34a and 34b provided on the suspension beam portion 31 of the coiled metal wire suspension device 3 are provided in the excitation units 1A and 1B. It is made to mount in the mounted mounting parts 18a and 18b. After this placement is completed, the connection between the locking portions 32a and 32b and the traveling hoist is removed. Thus, the coiled metal wire rod suspension device 3 is placed on the device 1 of the present invention, and the entire steel wire rod 5 is completely immersed in the treatment liquid 7 (for example, sulfuric acid aqueous solution) of the immersion treatment bath 6. If necessary, the liquid level of the treatment liquid 7 is adjusted.

  Subsequently, the vibration motors 14a and 14b provided in the vibration units 1A and 1B are operated to apply vibrations to the vibration units 11a and 11b provided in the vibration units 1A and 1B. Since the suspension beam portion 31 is given horizontal and vertical vibration components by the vibration of the excitation portions 11a and 11b, the coiled metal wire suspended from the C-shaped hook portion 33 is only vibrated in the vertical direction. Not at the same time. Thus, the treatment liquid can be brought into contact with the entire surface of the steel wire 5 while providing stable vertical movement and rotational motion to the steel wire 5 suspended from the C-shaped hook portion 33.

  After the treatment in the immersion treatment bath 6 is completed, the coiled metal wire suspension device 3 can be connected to the traveling hoist by the locking portions 32a and 32b, pulled upward, and moved to another treatment bath.

  The apparatus of the present invention is, for example, continuously transported to various immersion baths by a traveling hoist in a state where a metal wire wound in a coil shape (particularly a coiled steel wire material) is suspended from a C-shaped hook and suspended. It can be used for a surface treatment method, in particular, a technique for vibration and pickling.
