[0022] Please refer toFigures 1-5 As shown, an oil spraying traction device for steel-cored aluminum stranded conductor, comprising: a box body 1, a first drive motor 2 is installed on one side of the box body 1, a traction wheel 3 is fixedly connected to the output end of the first drive motor 2, both ends of the traction wheel 3 are rotatably connected inside the box body 1, both sides of the box body 1 are provided with a sliding groove 4, a second drive motor 5 is symmetrically installed on the upper surface of the box body 1, a bidirectional threaded rod 6 is fixedly connected to the output end of each of the two second drive motors 5, both ends of the two bidirectional threaded rods 6 are rotatably connected inside the box body 1, a first connecting frame 7 and a second connecting frame 8 are threadedly connected to the two bidirectional threaded rods 6, a compression wheel 9 is rotatably connected inside the first connecting frame 7 and the second connecting frame 8, a limiting plate 10 is fixedly connected to both ends of the compression wheel 9, the two limiting plates 10 are respectively located outside the first connecting frame 7 and the second connecting frame 8, a protective pad 11 is installed on the surface of the compression wheel 9 and the traction wheel 3, the first connecting frame 7 and the second connecting frame 8 are slidably connected inside the sliding groove 4, an oil storage cotton 12 is arranged inside the first connecting frame 7 and the second connecting frame 8, a ball 13 is rotatably connected inside the first connecting frame 7 and the second connecting frame 8, and the ball 13 is attached to the surface of both ends of the compression wheel 9;

[0023] Steel core aluminum stranded wire needs to pass through traction device for drawing forming in production process. In order to make the distance between traction wheel 3 and pressing wheel 9 in the traction device meet the placement of steel core aluminum stranded wire of different sizes, so that the device can pull the steel core aluminum stranded wire of different sizes, a steel core aluminum stranded wire oil injection traction device is provided. In actual use, one end of the steel core aluminum stranded wire is inserted between the limiting plate 10 and the traction wheel 3 from the wire inlet pipe 16. Two groups of second driving motors 5 are started by the external control box, driving two groups of bidirectional threaded rods 6 to rotate synchronously. Because the threads on the bidirectional threaded rods 6 match the internal threads of the first connecting frame 7 and the second connecting frame 8, when the bidirectional threaded rods 6 rotate, the first connecting frame 7 and the second connecting frame 8 can be driven to move synchronously, that is, the two ends of the pressing wheel 9 can be driven to move synchronously, ensuring the stability of the pressing wheel 9, thereby improving the stability of the pressing of the steel core aluminum stranded wire. The height of the pressing wheel 9 can be adjusted according to the size of the steel core aluminum stranded wire, so that the device can pull the steel core aluminum stranded wire of different sizes. During the descent of the second connecting frame 8, one end of the spring 15 is pressed by the inner wall of the box 1, and the pressure generated is transmitted into the pressure detector 14. The pressure value detected by the pressure detector 14 is transmitted into the external control box. When the pressure value reaches the pressure value that the steel core aluminum stranded wire to be pulled can bear, the two groups of second driving motors 5 are turned off by the external control box, so that the pressing wheel 9 stops descending, thereby avoiding damage to the surface of the steel core aluminum stranded wire due to excessive pressure, avoiding affecting the smoothness of traction, and avoiding the case that the steel core aluminum stranded wire is misaligned due to insufficient pressure during traction. The first driving motor 2 is started by the external control box, driving the traction wheel 3 to rotate. The traction wheel 3 is attached to the steel core aluminum stranded wire, so that the steel core aluminum stranded wire can be pulled. When the steel core aluminum stranded wire is pulled under stress, the pressing wheel 9 attached thereto rotates. When the pressing wheel 9 rotates, the friction between the two ends and the ball 13 drives the ball 13 to rotate, so that the ball 13 passes through the oil storage cotton 12, so that its surface has lubricating oil, which can improve the smoothness of the rotation of the two ends of the pressing wheel 9 inside the first connecting frame 7 and the second connecting frame 8, avoid the case that the pressing wheel 9 is stuck when rotating under stress, and connect the oil injection nozzle 19 and the external oil pump to spray oil between the traction wheel 3 and the pressing wheel 9, so that the steel core aluminum stranded wire can be treated by oil injection, reducing the friction between the steel core aluminum stranded wire and the traction wheel 3 and the pressing wheel 9, thereby reducing the problem of wear on the surface of the steel core aluminum stranded wire during traction, thereby avoiding the problems of bending and sticking of the steel core aluminum stranded wire during traction.
