The first motor can drive the U-shaped rod to rotate, and cooperate with the telescopic adjustment of the second cylinder to adjust the attachment angle on the outer surface of the cable, thereby repairing deformed cables.

[0037] The upper cutter 13 is mounted on the telescopic end of the hydraulic cylinder 4 and presses downward vertically.

[0038] The lower cutter 14 is fixed to the inner wall of the operating box 3 and is designed to be offset and non-overlapping with the upper cutter 13 to generate a shearing force.

[0039] Offset cutting can reduce tool wear and avoid excessive deformation of the cable due to squeezing.

[0040] The inclined guide platform 2 inside the operation box 3 automatically guides the cut wires into the collection box, reducing the frequency of manual cleaning.

[0046] The ball 29 is embedded in the end of the connecting column 31 and directly contacts the cable surface to reduce friction;

[0047] The second motor 28 drives the connecting shaft 26 to rotate, which causes the rotating shaft 25 to rotate through the synchronous wheel 27 and the synchronous belt, prompting the spiral rod 30 to rotate. The spirally arranged multi-point balls 29 roll along the spiral trajectory and crush the flat head, causing the metal wire core to plastically deform and gradually restore the circular cross-section.

[0048] A second motor 28 is provided at one end of the U-shaped frame 23, and a connecting shaft 26 is provided at the output end of the second motor 28. The connecting shaft 26 is rotatably connected to the U-shaped frame 23. A synchronous wheel 27 is provided on the outside of each end of the rotating shaft 25 and the connecting shaft 26. The two synchronous wheels 27 are connected on the outside by a commonly provided synchronous belt. A U-shaped rod 18 is provided on the outside of the two sets of sliders 21. A first motor 19 is provided at one end of the support frame 10 corresponding to the U-shaped rod 18. The output shaft of the first motor 19 is fixedly connected to the U-shaped rod 18.

[0049] The first motor 19 drives the U-shaped rod 18 to rotate, and the slider 21 connected to the U-shaped rod 18 can slide in the C-shaped ring frame 11, so that the contact angles of the two sets of card shells 22 and balls 29 with the cable are continuously adjusted, and the two card shells 22 are symmetrically arranged to ensure that the rolling angles are relatively symmetrical.

[0050] A cable processing method, using the above-mentioned cable processing device, includes the following methods:

[0051] S1: One end of the cable is pulled through the threading drum 9, passed through the interior of the cable conveyor roller 8, and then guided to the upper cutter 13 and the lower cutter 14 through the drum shell 7;

[0052] S2: The first cylinder 17 drives the carriage 15 to the outside of one end of the cable. The electric telescopic rod 34 drives the clamping rod 35 and the arc shell 32 downward, causing the arc shell 32 to press the cable to the positioning shell 36. At this time, the hydraulic cylinder 4 drives the upper cutter 13 downward to offset the lower cutter 14 and cut the cable.

[0053] S3: The cut cable is pressed by the arc shell 32 and the positioning shell 36 and transported to the inside of the C-shaped ring frame 11 through the first cylinder 17 until the incision is located between the two card shells 22. The second cylinder 24 drives the U-shaped frame 23 to approach each other until it is attached to the upper and lower outer surfaces of the cable. The second motor 28 rotates the driving connecting shaft 26, causing the synchronous belt to drive the corresponding synchronous wheel 27 to rotate, and the transmission shaft 25 below causes the external screw rod 30 of the rotating shaft 25 to rotate. The ball 29 at the end of the corresponding connecting column 31 rolls over the outer surface of the flat head cable to perform multi-point rolling extrusion. By continuously converting mechanical energy into plastic deformation energy, the flat part is gradually rolled into a round shape.

[0054] Working principle: When in use, the cable is passed through the threading drum 9, pulled to the drum shell 7 by the cable conveyor roller 8, and finally positioned between the upper cutter 13 and the lower cutter 14. The first cylinder 17 pushes the slide 15 to move to the end of the cable, and the electric telescopic rod 34 drives the arc shell 32 downward to cooperate with the friction rod 37 at the bottom to clamp the cable;

[0055] The hydraulic cylinder 4 drives the upper cutter 13 to move downward, and the fixed lower cutter 14 is offset to cut, forming a flat head at the incision. The wire clamping mechanism then transfers the cut wire to the inside of the C-shaped ring frame 11, so that the incision is located between the two sets of wire rolling and rounding mechanisms.

[0056] The second cylinder 24 pushes the U-shaped frame 23 toward the cable, so that the ball bearings 29 are in close contact with the surface of the flat head. The second motor 28 drives the rotating shaft 25 to rotate through the synchronous wheel 27 and the synchronous belt, driving the multiple connecting columns 31 on the screw rod 30 to revolve. The ball bearings 29 at the ends of the connecting columns 31 roll the surface of the flat head of the cable in a spiral trajectory. By continuously converting mechanical energy into plastic deformation energy, the flat part is gradually rolled back to a round shape. After the rounding is completed, the wire rolling mechanism is reset, the wire clamping mechanism releases the cable, and the cut cable slides out through the inclined guide table 2, and the device is ready for the next processing.

[0057] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the invention as claimed.
