According to the standard regulations, the oxygen content is not more than 0.02%, the total impurity content is not more than 0.05%, and the purity of copper is greater than 99.95%. The oxygen-free copper rod is a high-purity copper material with excellent electrical conductivity, thermal conductivity, and corrosion resistance. It is an important material for making electrical equipment such as wires, cables, transformers, generators, and motors. Its high electrical conductivity can reduce current noise and losses and improve the efficiency of electrical equipment. The process of the oxygen-free copper rod includes: melting electrolytic copper, heat preservation, cooling, crystallization, traction, and coiling, and a coiling device is required during the coiling process.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 - 5 , an oxygen-free copper rod winding device, including a winding device for double-station winding of copper rods, a guiding device for limiting and lifting and guiding the copper rod winding is arranged behind the winding device, and further includes a commutation device installed on the guiding device for bending the copper rod and swinging to change the bending direction, and a shearing device for cutting the copper rod from both sides is arranged in front of the commutation device.

[0026] In this embodiment: The winding device includes a winding frame 101, two winding discs 102 are symmetrically arranged on both sides above the winding frame 101, a winding motor 103 is installed below the winding disc 102, the winding frame 101 is made of 45# material, the shape of the winding disc 102 is circular, and the winding frame 101 supports the winding motor 103 to drive the winding disc 102 to rotate for winding the copper rod;

[0027] In this embodiment: The guiding device includes a support frame 201. An electric push rod 202 is installed on the top of the support frame 201. A lifting plate 203 is arranged at the bottom of the electric push rod 202. A guiding plate 204 is arranged in front of the lifting plate 203. Two guiding rollers 205 are symmetrically installed on both sides below the guiding plate 204. A supporting roller 206 is arranged in front of the guiding roller 205. The lifting plate 203 is slidably connected to the support frame 201, and the guiding plate 204 is welded to the lifting plate 203. The copper rod is sequentially passed between the two guiding rollers 205 and between the two supporting rollers 206, and after being bent by the reversing device, it is wound on the winding disc 102 on this side for winding. At the same time, the support frame 201 supports the electric push rod 202 to shorten, driving the guiding plate 204 to move downward through the lifting plate 203, so that the copper rod is evenly wound upward;

[0028] In this embodiment: The reversing device includes a rotating seat 301. A swing arm 302 is installed in the rotating seat 301. The swing arm 302 is hinged to the rotating seat 301. An installation plate 303 is arranged at one end of the swing arm 302 away from the rotating seat 301 below. Two bending rollers 304 are symmetrically arranged on both sides below the installation plate 303. A worm gear 305 is arranged on the top of the rotating seat 301. A worm 306 is meshed behind the worm gear 305. A reversing motor 307 is installed on one side of the worm 306. The worm gear 305 is connected to the swing arm 302 by a flat key.

The reversing motor 307 drives the worm 306 to rotate and mesh with the worm gear 305 to drive the swing arm 302 to swing to one side under the support of the rotating seat 301, so that the bending rollers 304 bend the copper rod under the support of the supporting roller 206, and make it bend and wind on the winding disc 102 on this side. After the winding on this side is completed, the shearing device cuts off the copper rod. Subsequently, repeat the above steps to make the swing arm 302 drive the bending rollers 304 to move to the other side through the installation plate 303, and bend the copper rod in the direction of the idle winding disc 102 to complete the reversing;

[0029] In this embodiment: The shearing device includes a shearing frame 401. A shearing motor 402 is arranged on one side of the shearing frame 401.

Then, drive the worm 306 to rotate by the reversing motor 307 to engage with the worm wheel 305, driving the swing arm 302 to swing to one side under the support of the rotating seat 301, so that the bending roller 304 bends the copper rod under the support of the supporting roller 206, making it bend and wind around the winding disc 102 on this side. Then, the winding frame 101 supports the winding motor 103 to drive the winding disc 102 to rotate, winding up the copper rod. At the same time, the support frame 201 supports the electric push rod 202 to shorten, driving the guide plate 204 to move downward through the lifting plate 203, so that the copper rod is evenly wound upward; after the winding on this side is completed, the shearing frame 401 supports the shearing motor 402 to drive the left and right threaded screw rod 403 to rotate, thereby pushing the two shearing blades 404 to move relatively to cut off the copper rod. Then, repeat the above steps to make the swing arm 302 drive the bending roller 304 to move towards the idle side through the mounting plate 303, bending the copper rod towards the direction of the idle winding disc 102 to complete the commutation. At the same time, the electric push rod 202 drives the guide plate 204 to move downward through the lifting plate 203, so that the copper rod starts to wind from the bottom of the winding disc 102, realizing automatic roll change.
