Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for expanding a converged coil wire or for converging the expanded coil wire.

[0002]

2. Description of the Related Art Generally, after hot-rolling or heat-treating a coil wire material such as steel, the coil wire material is bound by a steel wire or a steel strip for convenience of transportation, storage and the like. afterwards,
When pickling this coil wire, it is desirable to unwind the steel wire or steel strip that bundles the coil wire, and deploy this coil wire in the axial direction of the coil so that the surface of the coil wire is sufficiently exposed to the pickling solution. . In addition, when the coil wire is developed and processed in this way, and then transported or stored,
It is desirable to reduce the apparent volume by converging the coil wire in the coil axial direction.

Conventionally, when expanding or converging a coil wire, in particular, to expand a coil wire having a large wire diameter or a coil wire having a large weight, the coil is voluntarily expanded,
In order to converge the coil wire, a compression plate or a worker manually applies a compressive force from both ends of the coil wire in the coil axial direction.

[0004]

However, according to the conventional method, when the coil wire rod is unfolded, the coil cannot be sufficiently expanded, and when the coil wire rod is converged, a large force is applied to the coil wire rod. However, there was a problem in that the coil wire rod was damaged due to the addition of The present invention has been made in view of the above situation, and an object thereof is to develop a converged coil wire or to converge the expanded coil wire without forming a flaw in the coil wire. It is to provide an efficient and economical device capable of converging and expanding.

[0005]

In order to achieve the above-mentioned object, a coil wire rod unfolding and converging device of the present invention comprises: (1) a threaded rod having a threaded portion whose thread pitch monotonically increases from one end to the other end. And a bearing that rotatably supports both ends of the screw rod, and a support base that supports the bearing and has one end supported by a pillar provided on a base and the other end that allows the wire rod coil to move in and out. And a screw rod rotating means for rotating the screw rod.

(2) In the device for converging and expanding a coil wire according to the above (1), instead of the screw rod, the winding direction of the screw is opposite to the switching portion at the center, and the switching portion is provided at both ends. It is characterized in that the threaded rod has a threaded portion whose screw pitch increases monotonically. (3) In the apparatus for deploying and converging a coil wire rod according to (1) or (2), the screw rods are two screw rods, which are provided in parallel with each other and the winding directions of the screws are provided in mutually opposite directions. At the same time, the two screw rods are rotated in opposite directions.

[0007]

Operation: The unwound coil wire is carried by the carrier device, and the screw rod is passed through the hollow portion of the coil wire. At this position, the conveying device is lowered or the screw rod is raised to support the coil wire only with the screw rod. In this state, the screw rod is rotated by the screw rod rotating means. By supporting both ends of the screw rod by bearings, the rotation of the screw rod is made smooth. The bearing is supported by a support base. One end of this support base is supported by a column that is erected on the base, and the other end of the support base is a free end, allowing the coil wire to enter and exit.

In the apparatus for converging and expanding a coil wire according to claim 1 of the present invention, since the thread pitch of the screw rod is monotonically increased in one direction, when the screw rod is rotated while the coil wire is supported. The wire rod portion inside the coil wire rod, which is in contact with the screw rod, slides on the screw thread of the screw rod, and the wire rod portion is guided by the screw thread as the screw rod rotates and the shaft of the screw rod is guided. Move in the direction. The wire rod that slides on the side of the threaded rod having the larger thread pitch moves in the axial direction of the screw rod faster than the wire rod that slides on the side of the smaller thread pitch. The coil wire rod expands or converges in the axial direction of the coil due to the difference in the moving speed of the wire rod.

That is, when the screw rod whose screw pitch monotonously increases from the root to the tip of the screw rod is rotated in the same direction as the winding direction of the screw, the coil wire rod wound around the screw rod converges. Further, if the same screw rod is rotated in the direction opposite to the winding direction of the screw, the coil wire rod wound around this screw rod is expanded in the coil axial direction. According to a second aspect of the present invention, there is provided a coil wire rod spreading and converging device having a screw switching portion substantially at the center of the length of the threaded rod, and the screw winding direction is opposite with the switching portion as a boundary, and A threaded rod having a threaded portion whose thread pitch monotonically increases toward both ends of the rod is used. When the screw rod is rotated while the coil wire rod is wound over the screw switching portion of the screw rod, both ends of the coil wire rod move in opposite directions along the coil axis. The wire rod coil can be expanded or converged more effectively than the described coil wire rod expansion and convergence device.

According to a third aspect of the present invention, there is provided two coil rods for the coil wire rod deploying and converging device.
The two screw rods are provided in parallel with each other, and the winding directions of the screws of these two screw rods are provided in mutually opposite directions. Then, the two screw rods are rotated in opposite directions while supporting the coil wire. As a result, the wire coil can be expanded or converged without the coil wire rotating together with the rotation of the screw rod.
