[0006] Preferably, the wire threading and guiding mechanism includes a housing fixedly arranged on the upper surface of the workbench. Inside the housing, a cable conveying roller machine is arranged. The operation box is located at one side edge of the housing. At one end of the upper surface of the workbench far from the operation box, a wire threading cylinder is arranged. At a position corresponding to the axis of the wire threading cylinder on one side inside the operation box, a cylinder shell is arranged.

[0007] Preferably, the wire cutting mechanism includes a hydraulic cylinder arranged on one side inside the operation box. Above the hydraulic cylinder, an L-shaped frame is arranged. The L-shaped frame is fixedly connected to the workbench. The telescopic end of the hydraulic cylinder is provided with an upper cutting knife. On one side of the inner wall of the operation box and below the upper cutting knife, a lower cutting knife is arranged in a staggered manner. The bottom of the lower cutting knife is installed inside the operation box through a fixed plate arranged. Below the operation box, an inclined guiding table is arranged.

[0011] Preferably, a second motor is provided at one end inside the U-shaped frame, a connecting shaft is provided at the output end of the second motor, the connecting shaft is rotatably connected to the U-shaped frame, synchronous wheels are provided outside the rotating shaft and one end of the connecting shaft, the two synchronous wheels are connected outside by a commonly provided synchronous belt, a U-shaped rod is provided on the outer side of the two groups of sliders, a first motor is provided at one end inside the support frame and corresponding to the U-shaped rod, and the output shaft of the first motor is fixedly connected to the U-shaped rod.

[0012] A cable processing method, using the above-mentioned cable processing device, includes the following use methods:

[0013] S1: Pull one end of the cable through the threading drum, pass it through the inside of the cable conveying roller machine in turn, and then guide it to the upper cutter and the lower cutter through the drum shell;

[0014] S2: The first cylinder drives the carriage to move to the outside of one end of the cable, and the electric telescopic rod drives the clamping rod and the arc shell to press down, so that the arc shell presses the cable to the positioning shell. At this time, the hydraulic cylinder drives the upper cutter to move downward and displace with the lower cutter to cut the cable;

[0015] S3: Under the pressing of the arc-shaped shell and the positioning shell, the cut cable is conveyed into the inner part of the C-shaped ring frame through the first cylinder until the cut is located between the two clamping shells.

The second motor rotates to drive the connecting shaft to rotate, causing the synchronous belt to drive the corresponding synchronous wheels to rotate, transmitting to the lower rotating shaft, causing the spiral rod outside the rotating shaft to rotate. The balls at the ends of the corresponding connecting columns roll on the outer surface of the flat-headed cable for multi-point rolling extrusion. Through the continuous conversion of mechanical energy into plastic deformation energy, the flat part is gradually rolled into a circle.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] Through the provided wire threading and guiding mechanism, the cable can be automatically positioned, and together with the wire clamping and moving mechanism, the cable is conveyed to the tangent mechanism to complete the cutting operation of the cable, improving the efficiency of single-cable processing.

[0018] Through the provided wire clamping and moving mechanism, cables of multiple calibers can be supported for operation. The arc-shaped shell wraps the cable from above to the positioning shell, and it is relatively stable both when clamping the cable and positioning the cable later.

[0019] Through the provided wire rolling and rounding mechanism, using a spiral rolling design, the flat head can be quickly restored to a circle, and the rolling contact of the balls also reduces the scratching of the cable skin. The symmetrically arranged wire rolling and restoring mechanisms above and below can stably attach the cable between the two spiral rods when rounding the end of a shorter cable. Moreover, the first motor can drive the U-shaped rod to rotate, cooperating with the telescopic adjustment of the second cylinder to adjust the attachment angle on the outer surface of the cable, and the deformed cable can be repaired.

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

[0047] The second motor 28 drives the connecting shaft 26 to rotate, and causes the rotating shaft 25 to rotate through the synchronous wheel 27 and the synchronous belt, prompting the spiral rod 30 to rotate, and the spirally arranged multi-point balls 29 roll along the spiral track to 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.

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

[0051] S1: Pull one end of the cable through the wire threading cylinder 9, sequentially pass through the inside of the cable conveying roller machine 8, and then introduce it to the upper cutter 13 and the lower cutter 14 through the cylinder shell 7;

[0052] S2: The first cylinder 17 drives the carriage 15 to move to the outside of one end of the cable. The electric telescopic rod 34 drives the clamping rod 35 and the arc-shaped shell 32 to press down, prompting the arc-shaped shell 32 to press against the cable to the positioning shell 36. At this time, the hydraulic cylinder 4 drives the upper cutter 13 to move down and be misaligned with the lower cutter 14 to cut the cable;

[0053] S3: The cut cable is pressed by the arc-shaped shell 32 and the positioning shell 36 and is conveyed to the inside of the C-shaped ring frame 11 by the first cylinder 17 until the cut is located between the two clamping shells 22. The second cylinder 24 drives the U-shaped frames 23 to approach each other until they adhere to the outer surfaces on the upper and lower sides of the cable. The second motor 28 rotates to drive the connecting shaft 26 to rotate, causing the synchronous belt to drive the corresponding synchronous wheels 27 to rotate, driving the lower rotating shaft 25, so that the screw rod 30 outside the rotating shaft 25 rotates, and the balls 29 at the ends of the corresponding connecting columns 31 roll on the outer surface of the flat-headed cable for multi-point rolling extrusion. Through continuous conversion of mechanical energy into plastic deformation energy, the flat part is gradually rolled into a circular shape.

[0054] Working principle: When in use, the cable is inserted from the wire threading cylinder 9, pulled by the cable conveying roller machine 8 to the cylinder shell 7, and finally positioned between the upper cutter 13 and the lower cutter 14. The first cylinder 17 pushes the carriage 15 to move to the end of the cable, and the electric telescopic rod 34 drives the arc-shaped shell 32 to press down, cooperating with the friction resistance rod 37 at the bottom to clamp the cable;

[0055] The hydraulic cylinder 4 drives the upper cutter 13 to move down, shear misaligned with the fixed lower cutter 14, a flat head is formed at the cut, and the wire clamping mechanism then transfers the cut cable to the inside of the C-shaped ring frame 11, making the cut located between the two wire rolling and roundness restoring mechanisms;

[0056] The second cylinder 24 pushes the U-shaped frames 23 to approach the cable, making the balls 29 closely adhere to the surface of the flat head. The second motor 28 drives the rotating shaft 25 to rotate through the synchronous wheels 27 and the synchronous belt, driving the multiple connecting columns 31 on the screw rod 30 to revolve. The balls 29 at the ends of the connecting columns 31 roll on the surface of the cable flat head in a spiral trajectory. Through continuous conversion of mechanical energy into plastic deformation energy, the flat part is gradually rolled and restored to a circular shape. After the roundness restoration is completed, the wire rolling mechanism resets, the wire clamping mechanism releases the cable, and the cut cable slides out through the inclined guiding platform 2, and the device is ready for the next processing.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
