Abstract

PURPOSE:To prevent a wire rod coil from being spread and deformed during its transferring operation by bundling the wire rod coil wound after the rolling, inserting a binding material into the inner hollow part of the coil during transfer to a binder and binding the coil at one or more places in a direction orthogonal to the circumferential direction of the coil. CONSTITUTION:A rolled wire rod wound in the form of a ring by a winder 1 is bundled in the form of a coil by a bundling device 2. Before the bundled coil 3 is transferred to and loaded on a transfer/loading device 6 for upsetting, transferring and loading the bundled coil, a binding material 5 is inserted into the inner hollow part of the bundled coil 3 to bind it at two places. Then, the wire rod coil 3 is transferred to a coil transferring jig 7 by the transfer/ loading device 6. According to this arrangement, the wire rod coil 3 can be prevented from being deformed and spread during its transferring operation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming a wire coil.

[0002]

2. Description of the Related Art In a manufacturing process of a wire coil, heating->rolling->winding->bunching-> bundling process, as a method for bundling while maintaining the coil shape at the time of bundling a wire coil, the steps from bundling to bundling as shown in FIG. Coil transfer jig (coil hanger) 7
There is a technique of preventing the deformation and expansion of the wire rod coil during the conveyance process by making the shape of the wave shape 8 (Japanese Utility Model Publication No. 59-5031).

[0003]

According to the conventional means, the vibration of the coil transfer jig during the coil transfer causes the wire rod to jump over the corrugated portion, resulting in the deformation of the wire rod coil or the coil transfer repair at the time of pressurizing the wire rod coil binding. There is a defect that the waveform of the tool is deformed and damaged. The present invention has been made to solve such a drawback, and an object of the present invention is to prevent coil expansion and deformation in the conveying process up to the step of binding wire coils.

[0004]

SUMMARY OF THE INVENTION The gist of the present invention is to provide a binding material in a coil inner hole portion immediately after focusing of a wire rod coil rolled after rolling the wire rod or during a coil conveying process from the bundle to the binding. A method of forming a wire rod coil, which comprises inserting and binding at least one place in a direction perpendicular to a circumferential direction.

【Example】

Example 1 As shown in FIG. 1 (a), after the wire rod is rolled, the wire rod wound into a ring shape by the winding machine 1 is a focusing device (focusing tab).
It is focused into a coil at 2. Before transferring the bundled wire rod coil 3 to a transfer machine 6 for turning and transferring, the wire rod coil was bound at two places by an iron wire (bundling material) 5. In the figure, 4 is a sail. After that, the wire rod coil 3 was transferred to the coil transfer jig 7 by the transfer device 6 and transferred, and the transfer state of the wire rod coil is as shown in FIG.
By bundling, it was possible to prevent coil deformation and spreading during wire rod coil transportation.

Embodiment 2 In FIG. 1 (a), a wire coil 3 wound in a ring shape by a winding machine 1 and focused in a coil shape by a focusing device (focusing tab) 2 is transferred by a transfer machine 6. When transferring to the coil transfer jig 7, the wire coil 3 on the transfer machine 6 is moved by the iron wire 5
I was united. The transfer state of the wire rod coil after transferring the wire rod coil 3 to the coil transfer jig 7 was able to prevent the coil deformation / spreading during the wire rod coil transfer as in the first embodiment.

Example 3 After rolling the wire rod, the wire rod wound on the ring by the winder 1 is bundled into a coil by the bundle focusing device (focusing tab) 2, and the bundled wire rod coil 3 is transferred. After being transferred to the coil transfer jig 7 by the machine 6, the wire rod coil 3 on the coil transfer jig 7 was bound at two places by the iron wire 5 (state shown in FIG. 1B). As a result, the wire coils are transported in the first and second embodiments.
In the same manner as the above, the binding by the numbered wire 5 could prevent the coil from being deformed and spread during the conveyance of the wire rod coil.

[0008]

As described above, according to the wire rod coil forming method of the present invention, the deformation and spread of the wire rod coil during conveyance can be prevented more reliably, and the coil which is a problem of the prior art. The effect that deformation and damage of the corrugated portion of the transfer jig can be eliminated by changing the corrugated portion of the coil transfer jig to a flat structure.
