Abstract

PROBLEM TO BE SOLVED: To implement the stable pickling of a coil so that the coil is not toppled when the coil is placed on a rotating device by providing an uneven lining on a coil receiving part of the rotating device disposed outside a tank. SOLUTION: A wire coil 1 placed on a C-hook is automatically placed on a wire rotating device 4 while carried. An uneven lining 6 is provided on a coil receiving part 5 of this wire rotating device 4, the wire coil 1 is allowed to bite in the undulation so as not to be toppled when the wire coil 1 is placed on the wire rotating device 4 from the C-hook, and the wire rotating device 4 is rotated. The uneven lining 6 is formed by joining, for example, a resin material. Facility troubles that the wire coil 1 is detached from the hook, or the packing style is deformed can be eliminated, and generation of the irregular pickling can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire rotating device for pickling coils.

[0002]

2. Description of the Related Art Conventionally, in a pickling operation of a wire rod, an overlapped portion of wire rods is generated, and the overlapped portion is not pickled, and the uncontacted portion is not pickled because the hook contact portion of the wire is not pickled. Inferior quality due to washing parts. In order to prevent this, a method has been adopted in which the contact portion is shifted by rotating a wire coil during pickling. In addition, in the existing continuous pickling line, as shown in FIG. 6, the swash plate 2 is provided with the wire coil 1 in a bath, and the wire coil 1 is rolled on the swash plate 2 in the pickling bath to solve the above problem. What they are doing is the reality.

[0003]

However, as shown in FIG. 6, when pickling is performed in a conventional pickling bath provided with a swash plate in a tank, the C hook contact portion moves by rolling. When rolling, there is a problem in that twisting occurs in the coil, and there is a problem of small bending and tangling, and the coil may come off the hook in the tank. Further, there are various problems such that equipment troubles occur frequently because an eccentric load is applied to the transfer device.

[0004]

Means for Solving the Problems In order to solve the above-mentioned problems, the present inventors have intensively developed and as a result, a rotating device is provided outside the tank to rotate the wire coil, and the coil is hooked up by a C hook. The present invention provides a pickling coil rotating device in which a coil receiving portion is provided with an uneven lining so that the coil receiving portion does not fall when placed on the rotating device. The gist of the invention is that, in the pickling coil rotating device, a rotating device is provided outside the tank, and the wire coil is placed on the coil receiving portion so as not to fall when the wire coil is placed on the wire rotating device from the C hook. A wire rotating device characterized by providing a lining having irregularities and pickling a wire coil while rotating the wire rotating device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. FIG. 1 shows an automatic conveying device for a wire coil according to the present invention. As shown in FIG. 1, this shows a state in which the wire coil 1 is automatically conveyed while being placed on the C hook 3. Automatic loading. That is, FIG. 2 is a schematic diagram of the wire rod rotating device according to the present invention. As shown in FIG. 3, the wire rod rotating device 4 is provided with a lining 6 having an uneven shape on the coil receiving portion 5 so that the wire coil does not fall back and forth when the wire coil is placed on the wire rod rotating device 4 from the C hook 3. By providing the unevenness of the lining 6 of the coil receiving portion 5, the wire rod 1 is made to bite into the unevenness of the wire, and then the wire rotating device 4 is rotated.

FIG. 4 is a view showing a state in which the wire rotating device according to the present invention is rotated. As shown in FIG. 4, if the lining 6 having the uneven shape is made of, for example, a resin material and is formed by joining the resin material, the wire rod coil 1 is used as the lining 6 having the uneven shape.
When the wire coil 1 rotates the wire rotating device 4 by a cylinder (not shown) in a state where the wire coil 1 bites into the undulation, the C hook contact portion 7 can be shifted as shown in FIG. The hook contact portion can be displaced and pickling can be performed, and uneven pickling due to the hook contact portion can be prevented. In addition, the wire rod rotating device enables smooth rotation acceleration by, for example, rotating with an air-hydro (pneumatic-to-hydraulic-conversion) type cylinder, and can rotate while alleviating the impact due to inertia at the time of starting and stopping.

[0007]

As described above, by disposing the rotating device outside the pickling tank according to the present invention and rotating the wire coil, the wire material comes off from the hook, the packing is distorted, and the crane is displaced. The problem of rust due to improper loading on the wire is eliminated, and the problem of rust caused by long-term exposure in the air is solved by installing it before the final finishing hydrochloric acid. This is a very excellent effect that can be performed.
