Embodiment 1
[0037] When unwinding a wire wound in a coil shape, use figure 1 The uncoiling auxiliary device 10 for the wire is shown to guide the uncoiled wire. As the five rotating bodies 1a to 1e, HRA88 was used, and the surface roughness Ra of the part contacting the wire rod was 0.2, and the material was made of cemented carbide, and the depth of the groove portion 1A was set to 10 mm. In addition, only one non-rotating member 2 is provided, and it is provided near the rotating body 1a. As the wire material, a hard steel wire is used.
Embodiment 2
[0039] The uncoiled wire rod was guided using the same uncoiling assisting device as in Example 1 except that the ring member 4 was not provided.
Embodiment 3
[0041] The uncoiled wire rod was guided using the same unwinding assisting device as in Example 1 except that the guide portion 3 and the ring member 4 were not provided.

To provide a wire unwinding auxiliary device capable of, compared to a conventional device, effectively preventing an unwound wire material from getting twisted, entangled or flawed. A wire unwinding auxiliary device used for guiding an unwound wire material when unwinding the wire material which is wound in a coiled shape. The device comprises a plurality of rotation members 1a-1e on which the unwound wire material is set to run therethrough, and a non-rotation member 2 provided adjacent to at least a rotation member 1a through which the wire material passes first in the plurality of rotation members 1a-1e, thereby a running path of the wire material is stabilized between the non-rotation member 2 and the rotation member 1a.
Description
technical field [0001] The present invention relates to a wire uncoiling assisting device (hereinafter also simply referred to as "uncoiling assisting device"). An auxiliary device for uncoiling wire rods used for finished wire rods. Background technique [0002] When unwinding a wire wound in a coil shape for processing, etc., it is important that the uncoiled wire does not twist, tangle, and prevent damage to the uncoiled wire as the semi-finished product quality of the wire. If the wire rod is twisted, tangled, damaged, etc., coiling failures, wire breakage, etc. due to these will frequently occur, making it difficult to mass-produce and process the wire rod. [0003] As a technique for preventing the twisting and entanglement of the wire, there is known an uncoiling assisting device that has a plurality of straightening rotating bodies for running the uncoiled wire and advancing the wire, and a device for pulling the uncoiled wire forward. A wire supply guide that guid...
