[0009] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0010] The embodiments of the present invention will now be described.

[0011] Example 1 like Figures 1-4 As shown in the figure, this embodiment discloses a high-voltage conductor bending device, which aims to solve the problems of existing devices being unable to achieve multi-angle bending, cumbersome operation, and poor accuracy. Its specific structure and working process are as follows: The high-voltage conductor bending device of this embodiment includes a main body 1 and a bending mechanism 2 mounted on the main body 1, wherein: The main body 1 is provided with an arc-shaped groove 101, and a fixed wheel 214 is rotatably installed in the arc-shaped groove 101. At the same time, a limit wheel 211 and a positioning component are also installed on the main body 1. The positioning component consists of a positioning cylinder 212 and a positioning rod 213. The bending mechanism 2 is fixedly connected to the main body 1 through a fixed frame 201. The fixed frame 201 is provided with a longitudinal guide rod 204 and a longitudinal push cylinder 202. A longitudinal sliding frame 203 is slidably sleeved on the longitudinal guide rod 204. The output end of the longitudinal push cylinder 202 is fixedly connected to the longitudinal sliding frame 203. The longitudinal sliding frame 203 is provided with a transverse guide rod 207 and a transverse push cylinder 205. A transverse sliding frame 208 is slidably sleeved on the transverse guide rod 207. The output end of the transverse push cylinder 205 is fixedly connected to the transverse sliding frame 208 through a push rod 206. The top of the transverse sliding frame 208 is fixed with a fixed rod 209 extending above the main body 1. A bending roller 210 is installed on the outside of the fixed rod 209, and the fixed rod 209 is adapted to the arc groove 101 on the main body 1. The longitudinal pushing cylinder 202 and the transverse pushing cylinder 205 are both equipped with stroke sensors, which are electrically connected with an external control system, the guide hole inner wall matched with the longitudinal guide rod 204 on the longitudinal sliding frame 203 is provided with a wear-resistant coating, and the sliding hole inner wall matched with the transverse guide rod 207 on the transverse sliding frame 208 is provided with a lubricating layer, and the outer wall of the bending roller 210 is wrapped with an elastic buffer layer made of rubber material.

[0012] The working principle of the present application is as follows: when in use, the high-voltage wire to be bent is placed between the two groups of bending rollers 210 and the limiting wheels 211, and specifically, the bending position of the high-voltage wire is aligned with the middle position of the limiting wheels 211. Then start the equipment, first, the positioning cylinder 212 runs, the output end of the positioning cylinder 212 drives the positioning rod 213 to first press the high-voltage wire against the outer wall of the limiting wheel 212, thereby playing a positioning and fixing operation on the high-voltage wire. Then the output end of the longitudinal pushing cylinder 202 drives the longitudinal sliding frame 203 to move longitudinally along the longitudinal guide rod 204, and the longitudinal sliding frame 203 drives the two groups of transverse sliding frames 208 to move longitudinally through the two groups of transverse guide rods 207, wherein each group of transverse sliding frames 208 and a group of bending rollers 210 are fixedly connected through the fixed rod 209. That is, at this time, the two groups of bending rollers 210 move under the action of the longitudinal pushing cylinder 202 to bend the high-voltage wire. At the same time, the two groups of transverse pushing cylinders 205 fixed on the two sides of the longitudinal sliding frame 203 run, and the two groups of transverse sliding frames 208 are synchronously pushed to move transversely through the two groups of pushing rods 206. Under the above composite action, the two groups of bending rollers 210 can bend the high-voltage wire, and at the same time, the extension distance of the longitudinal pushing cylinder 202 and the transverse pushing cylinder 205 can be controlled to adjust the bending angle of the high-voltage wire. At the same time, when the extension distance of the longitudinal pushing cylinder 202 and the transverse pushing cylinder 205 reaches the maximum limit, at this time, the two groups of bending rollers 210 will also move to the farthest distance from the initial position, and under the action of the fixed wheel 214, the high-voltage wire can be bent into a circle. In general, compared with the existing device which needs to frequently replace the mold and adjust the structure to realize the operation mode of different angle bending, the present application can complete multi-angle bending and bending into a circle through cylinder driving and parameter adjustment, greatly simplifying the operation process, without the need for professional personnel to repeatedly debug the equipment, ordinary operators can operate after simple training, significantly shortening the processing time of a single wire, especially suitable for batch wire processing scenes in power engineering, helping to improve the overall construction progress. The accurate locking of the positioning structure and the stable force of the composite drive avoid the problems of local extrusion deformation and wrinkles of the conductor in the processing due to uneven stress, ensure that the bending angle error is controlled in a very small range, and meet the strict requirements of the conductor precision in the scenes of substation high-voltage cabinet connection and transmission tower line arrangement; The uniform force and smooth forming effect in the bending process reduce the fatigue damage of the conductor caused by unreasonable bending, ensure the stability of the electrical performance of the high-voltage conductor, prolong the service life of the conductor, and reduce the maintenance cost of the power engineering in the later period. The device can realize bending at different angles and bending circle at different radii by parameter adjustment without replacing core components, and is suitable for processing requirements of high-voltage conductors of various specifications and different cross-sectional sizes. Whether it is outdoor line laying in power engineering construction, conductor replacement in power equipment maintenance, or internal conductor integration in power supporting facility installation, the device can complete the processing, break through the limitation of single application scene of the existing device, and provide a multifunctional and highly adaptive conductor processing solution for the power industry.
