[0017] The structure and other aspects of the straightening device of the present invention are further described in detail below through specific implementations and with reference to the accompanying drawings.

[0018] like Figures 1 to 4 As shown, the straightening device of the utility model includes a first rotating part 11, a bracket 13 and a driving part 15. The first rotating part 11 is rotatably mounted on the bracket 13, for example, rotatably mounted on the bracket 13 through a bearing. The driving part 15 can drive the first rotating part 11 to rotate. The first rotating part 11 has a frame 114 and a tube body 115 mounted on the frame 114, and the tube body 115 is for the wire to pass through. The tube body 115 is arranged in a W shape on the frame 114. In a specific embodiment, the tube body 115 is a hollow tube body with a smooth inner wall. For example, it is a tube body made of plastic material. The tube body 115 is fixed to the frame 114 by a plurality of fixing members 116.

[0019] In a preferred embodiment, the correction device of the utility model further comprises a second rotating part 12, which is rotatably mounted on a bracket 13, and the first rotating part 11 and the second rotating part 12 are arranged side by side along the direction indicated by the arrow X. The direction indicated by the arrow X is the axial direction of the metal wire, that is, the traveling direction of the metal wire. The straightening device of the utility model is used for calibrating a straight wire.

[0020] The first rotating part 11 rotates around the axial direction X of the wire in a first direction Y. In a specific embodiment, the first rotating part 11 has a first end 111 and a second end 112, and the first end is equipped with a first bevel gear 113. The second rotating part 12 rotates around the axial direction X of the wire in a second direction Z, and the second direction Z is opposite to the first direction Y. In a specific embodiment, the second rotating part 12 has a third end 121 and a fourth end 122, and the fourth end 122 is equipped with a second bevel gear 123. The rotation center of the first bevel gear 113 is coaxial with the rotation center of the second bevel gear 123.

[0021] The driving part 15 is used to drive the first rotating part 11 and the second rotating part 12 to rotate simultaneously. In a specific embodiment, the driving part 15 includes a driving motor and a third bevel gear 151, and the third bevel gear 151 is located between the first bevel gear 113 and the second bevel gear 123, and is respectively meshed with the first bevel gear 113 and the second bevel gear 123. The tube 115 passes through the center of the first bevel gear 113 and the second bevel gear 123 so that the wire can pass through the first bevel gear 113 and the second bevel gear 123.

[0022] In a preferred embodiment, the position of the fixing member 116 can be adjusted. The fixing member 116 has a through hole 117 and planes 118 at both ends, and the tube 115 can pass through the through hole 117. The fixing member 116 is arranged at different positions of the tube body 11 and makes the tube body 115 have a W-shaped layout. After the fixing member 116 passes through the hole on the frame 114, the fixing member 116 is fixed to the frame 114 by a screw 119. One end of the screw 119 abuts against the plane 118 to tighten the fixing member 116. The structure of the second rotating part 12 is the same as that of the first rotating part 11, except that the rotation direction is different, and the structure of the second rotating part 12 is not repeated.

[0023] When the straightening device for wire of the utility model is in operation, the metal wire extends from the second end 112 of the first rotating part 11 into the tube body 115, and extends from the first end 11 of the first rotating part 11, and then enters the tube body 115 from the fourth end 122 of the second rotating part 12 until it extends from the third end 121 of the second rotating part 12. The driving part 15 drives the third bevel gear 151 to rotate, and the third bevel gear 151 simultaneously drives the first bevel gear 113 and the second bevel gear 123 to rotate in opposite directions. The metal wire taken out from the coil has deformation stress, and the stress on the metal wire can be eliminated during the rotation of the first rotating part 11 and the second rotating part 12, so that the metal wire is straightened. The straightening device of the utility model can continuously straighten the metal wire on the coil in an automated manner.
