[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coiled steel wire suspended from a C-shaped hook and conveyed, immersed in an acid pickling tank, and vibrated by a vibrating body while being suspended by the C-shaped hook. The present invention relates to an apparatus for pickling a vibrating steel wire by vibration pickling.

[0002]

2. Description of the Related Art Conventionally, when pickling this kind of coiled steel wire, the steel wire is hung on a C-shaped hook and immersed in a cleaning tank, and the C-shaped hook is vibrated to give an acid. It was to be washed.

[0003]

However, this C
When pickling is performed by applying vibration to the hook, the contact surface between the receiving surface of the C-shaped hook and the steel wire inside the coil is in close contact with the cleaning liquid, and the cleaning liquid cannot be sufficiently cleaned. Since a problem occurs in the post-treatment step, the treatment time and the number of treatments in the pickling step are increased, and there is a problem that the efficiency is reduced.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and the position of the receiving surface of the C-shaped hook and the contact surface of the steel wire inside the coil can be displaced for efficient pickling. It is an object of the present invention to provide a pickling apparatus capable of performing the above-described steps.

[0005]

In order to solve the above-mentioned technical problem, the present invention supports an upper end of a C-shaped hook for suspending a workpiece on a lifting frame suspended from a traveling hoist so as to be able to move up and down. A pedestal mechanism comprising a pair of movable pedestals for receiving the elevating frame is provided above the washing tub, and the movable pedestal is provided with a vibrating body on a gantry frame supported by a buffer member such as an air spring. On the upper surface of the frame, a connecting member for forcibly connecting with the mounted elevating frame is provided, and the movable base is provided so that the elevating frame can be moved forward and backward below the movable base, and further, the pickling tank is The pickling device has a configuration in which a reversing device for reversing the work is provided at the bottom, and the reversing device is provided so as to be able to ascend and descend at a position where the work is pickled and a position where the work is reversed by the advancing and retreating operation of the receiving table mechanism.

[0006]

According to the above construction, picking can be performed by applying vibration to the C-shaped hook by the receiving mechanism, and from this pickling state, the receiving mechanism is retracted from the holding position by the opening / closing mechanism and moved up and down. The coil reversing mechanism formed at the bottom of the washing tank, which allows the frame to pass through, inherits the coil steel wire, displaces the position of the contact portion between the coil and the C-shaped hook, suspends the coil steel wire again, and opens and closes the mechanism. Is returned and placed on the receiving table mechanism to pickle the displaced contact portion.

When the outer periphery of the bar member 43a is brought into contact with the center bar member 43a, the radius R at which the bar members 43a and 43b are disposed is formed in a relation of R <r from the radius r of the coil steel wire W.
Since there is an interval h between the left and right reversing receiving bars 43b and 43c and the outer periphery of the coil steel wire W, the coil steel wire W comes into contact with the central bar member 43a, and further, the C-shaped hook 18 is slightly lowered and supported. When the point is removed, the coil steel wire rod W rolls to the left or right to roll, and the reversing receiving bar member 43b,
43c.

A case where the coil steel wire W is pickled by the pickling apparatus constructed as described above will be described. First, the coil steel wire W is hooked on the C-shaped hook 18 and the pulley device 8 shown in FIG. Pickling tank 20 along running rail 1
Is stopped at a predetermined position between the support beam portions 24 on the upper side of the support.
In this state, the elevating frame 10 is positioned above the support beam portion 24, and the coil steel wire W is positioned below the support beam portion 24 at the position a above the pickling tank 20. When the traveling hoist 2 is stopped in this way, the left and right working cylinders 38 on the support beam portion 24 are extended, the movable pedestal 27 is moved to oppose, and the elevating frame 10 is supported and is on standby.

In this state, the pulley device 8 is lowered, and the lifting frame 10, the C-shaped hook 18, and the coil steel wire W
Is lowered together. By this descent, the lifting frame 10

Since there is an interval h between the center bar member 43b and the center bar member 43a, the center bar member 43a rolls in the left or right direction and is received by the reverse receiving bar member 43b or 43c.
Due to this rolling, the engaging contact portion A of the coil steel wire W is displaced by a predetermined angle α from the center bar member 43a, that is, from the center line C.

When the pulley device is raised again in this state, the C-shaped hook 18 is hung around the pickled position B of the coiled steel wire W and lifted to the position a. The movable frame 27 is advanced by being extended, and stands by at the support position.
0 is lowered and forcibly connected to the movable base 27. Thereafter, the vibrating body 35 is operated again, and the initial engaging contact portion A
Is pickled. When the pickling of the initial engaging contact portion A is completed, the elevating frame 10 is raised, and when the coil steel wire W is hung at the position a, the operating cylinder 38 is shortened and the movable pedestal 27 retreats. Then, the traveling hoist 2 is operated, and the coil steel wire W is carried out. Thereafter, the coil steel wire W is sequentially pickled by the above operation.
