DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0023] See also Figure 1-2 The present invention provides a technical solution for a steel core aluminum stranded wire bending device: Embodiment 1: according to Figure 1 and Figure 2 As shown, it includes a base 1, a driving assembly, a bending mechanism and a supporting mechanism. A handle 3 is fixedly installed on the top of the base 1. The bending mechanism includes a U-shaped plate 41 and a fixing rod 45 installed in the U-shaped plate 41. A bending head 43 is mounted on the fixing rod 45.

[0024] The driving assembly includes a U-shaped seat 25 and a nut 21 fixedly installed on the top of the base 1. The left end of the U-shaped seat 25 is fixedly connected to the right side surface of the U-shaped plate 41. The inner thread of the nut 21 is connected to a screw 22. One end of the screw 22 is fixedly installed with a rotating disk 23, and the other end thereof passes through a through hole opened on the right side wall of the U-shaped seat 25 and is fixedly connected to a limit ring 24. The limit ring 24 is arranged in the U-shaped seat 25.

[0025] By rotating the screw 22 forward, under the action of the limit ring 24 and the U-shaped seat 25, the screw 22 drives the U-shaped plate 41 to move laterally, so that the bending head 43 moves toward the steel-core aluminum stranded wire to bend the steel-core aluminum stranded wire. Using the screw 22 to drive, a larger linear push-pull force can be generated through a smaller rotational torque, thereby achieving a force amplification effect, which is more labor-saving to a certain extent, and the screw 22 can accurately control the position and moving speed of the bending head 43 through rotation, thereby achieving fine bending angle and force control, reducing damage to the steel-core aluminum stranded wire during the bending process, and improving the operation quality.

[0026] The supporting mechanism includes a shell 52, an adjustment assembly and two high-strength gear rods 71. The top surface of the shell 52 is lower than the bottom surface of the U-shaped plate 41 to prevent the U-shaped plate 41 from colliding with the shell 52 during movement. The shell 52 is fixedly connected to the base 1 through two connecting arms 51, and a slot is opened on the top of the shell 52.

[0027] Two high-strength levers 71 are symmetrically arranged in the slots. Two retaining rings 72 are mounted on the upper section of the high-strength lever 71. A gap is provided between the two retaining rings 72 for placing the aluminum stranded wire. The steel-core aluminum stranded wire is supported by the lower retaining ring 72 so that the steel-core aluminum stranded wire will not fall off during the bending process.

[0028] The adjustment component includes a double-section threaded rod 62, the two sections of the thread of the double-section threaded rod 62 are in opposite directions, and the optical axes at both ends of the double-section threaded rod 62 are respectively provided with bearings, and the two bearings are respectively installed on the front side and the rear side of the inner wall of the shell 52, so that the double-section threaded rod 62 can rotate stably. One end of the double-section threaded rod 62 passes through the bearing and is installed with a rotating disk 2 63. Of course, in order to save effort, a drive motor can also be installed.

[0029] The two sections of the thread of the double-section threaded rod 62 are respectively threadedly connected with an internal thread block 61, and the two internal thread blocks 61 are respectively fixedly connected to the two high-strength gear rods 71. The rotation of the double-section threaded rod 62 is driven by rotating the rotating disk 2 63. The double-section threaded rod 62 adjusts the distance between the two high-strength gear rods 71 ​​during the rotation process, and is used in conjunction with the bending head 43 to ensure the accuracy and quality of the bending.

[0030] During specific use, the present invention provides a steel-core aluminum stranded wire bending device. First, the rotating disk 2 63 is rotated to drive the rotation of the double-section threaded rod 62. The double-section threaded rod 62 adjusts the spacing between the two high-strength gear rods 71 ​​during the rotation process. Then, the steel-core aluminum stranded wire is placed between the upper and lower retaining rings 72. At the same time, the part to be bent is aligned with the bending head 43. Then, the rotating disk 1 23 is rotated forward to drive the rotation of the lead screw 22. Under the action of the limit ring 24 and the U-shaped seat 25, the lead screw 22 drives the U-shaped plate 41 to move laterally, so that the bending head 43 moves toward the steel-core aluminum stranded wire to bend the steel-core aluminum stranded wire. Finally, after the steel-core aluminum stranded wire is bent, the rotating disk 1 23 is rotated in the reverse direction to keep the bending head 43 away from the steel-core aluminum stranded wire and remove the steel-core aluminum stranded wire.

[0031] Embodiment 2: Based on the first embodiment, the differences are as follows: Figure 1 and Figure 2 As shown, the U-shaped plate 41 is made of ordinary steel containing iron components, and the bending head 43 is made of iron.

[0032] The upper and lower sections of the fixing rod 45 are respectively sleeved with a large bending ring 42 and a middle bending ring 44, the inner diameter of the middle bending ring 44 is the same as the outer diameter of the bending head 43, the inner diameter of the large bending ring 42 is the same as the outer diameter of the middle bending ring 44, the inner circles of the large bending ring 42 and the inner circles of the middle bending ring 44 are surrounded by a plurality of magnetic strips, so that the middle bending ring 44 can be adsorbed on the U-shaped plate 41 or the bending head 43, and the large bending ring 42 can be adsorbed on the U-shaped plate 41 or the middle bending ring 44. By arranging the large bending ring 42, the bending head 43 and the middle bending ring 44, the large bending ring 42, the bending head 43 and the middle bending ring 44 can be split or used in combination according to the diameter of the steel-core aluminum stranded wire, so as to bend the steel-core aluminum stranded wires of different diameters, thereby improving the versatility of the device and making it more convenient to use.
