[0002] As a type of metal wire, cable can be roughly divided into insulated cables with an insulating sheath and a built-in metal cable core and pure metal high-voltage cables according to different application fields. During the production process, cables need to be cut into cables of a certain length using a cable cutting machine according to actual needs.

[0003] Patent No. CN107891106B discloses a cable cutting production line, which solves the problem that the cable production line needs to be stopped and restarted when the cutter is replaced in the existing process, affecting its production efficiency. The cable cutting production line includes a wire-paying device, a driving device and a cutting device arranged in sequence, and a buffer device is arranged between the wire-paying device and the cutting device. The buffer device includes a frame, a driving wheel and a driven wheel arranged in sequence along the length direction of the frame, the driving wheel is rotatably connected to one end of the frame and driven to rotate by a driving member, the driven wheel is rotatably connected to a sliding frame, and the sliding frame is driven by a traction mechanism to slide back and forth along the length direction of the frame, the cable is wound back and forth on the driving wheel and the driven wheel and transported to the cutting device via the driving device. When the cutter is replaced, the production line continues to operate, thereby reducing resource waste and improving production efficiency.

[0004] Although the above technical solution can improve the automation efficiency of cable cutting, it still has the following defects when cutting insulated cables: when the insulated cables cut by the above technical solution are connected and used later, the staff still needs to use a machine to peel off the outer insulation skin, which is not only time-consuming and labor-intensive, but also cannot guarantee the size of the exposed cable core.

[0005] Therefore, existing cable cutting machines still have the problem of being unable to accurately cut the cable and being unable to expose the cable cores of equal lengths at both ends of each cable segment after cutting. Summary of the Invention

[0055] A cutting method for a cable cutting machine that facilitates precise positioning, comprising:

[0056] S100, using the feed wheel assembly 3 to move the cable 8 to the position of the circular cutting knife group 43 at a constant speed, and stop the feed wheel assembly 3 after the end of the cable 8 exceeds a certain distance directly below the circular cutting knife group 43;

[0057] S200, use the second telescopic member 721 to move the horizontal plate 722 to above the first rack 411, at this time the second through hole 724 is aligned with the upper end of the second rack 511, and the first telescopic member 711 is used to control the lifting shell 712 and the horizontal plate 722 to perform a lifting movement with a stroke of H1cm, and the first rack 411 that follows the lifting movement of the horizontal plate 722 achieves the purpose of controlling the rotation of the first gear ring 42 by means of a transmission connection with the first gear ring 42, and the rotating first gear ring 42 controls the first movable pin 432 to move radially along the first radial guide rail 141 through the first arc guide rail 421, and the plurality of radially moving annular cutting blades 431 cut the first annular incision 81 on the surface of the cable 8, and the first reset spring 413 controls the plurality of annular cutting blades 431 to reset by driving the first rack 411 to rise;

[0058] S300, use the feed wheel assembly 3 to continue moving the cable 8, after T1s, the first annular incision 81 on the surface of the cable 8 moves to the bottom of the stripping knife group 53 and then the feed wheel assembly 3 is stopped. At the same time, the second telescopic member 721 is used to move the horizontal plate 722 to above the first rack 411 and the second rack 511. At this time, the upper end of the second rack 511 is distributed between the first through hole 723 and the second through hole 724. The first telescopic member 711 is used to control the lifting shell 712 and the horizontal plate 722 to perform a descending motion with a stroke of H1cm. The first rack 411 that is performing the descending motion controls the annular cutter group 43 to cut the second annular incision 83 on the surface of the cable 8 by means of a transmission connection with the first gear ring 42. The second rack 511 that follows the horizontal plate 722 to perform the descending motion The second gear ring 52 is controlled to rotate by means of a transmission connection with the second gear ring 52. The rotating second gear ring 52 controls the second movable pin 532 to move along the second radial guide rail 151 through the second arc guide rail 521, and the two radially moving stripping knife bodies 531 move into the first annular incision 81. During this process, the fixed ring 51 first slides into contact with the limit rod 542. When the fixed ring 51 is aligned with the limit rod 542, the elastic force of the third return spring 544 drives the limit rod 542 into the fixed ring 51 to fix the position of the stripping knife group 53. When the lifting assembly 71 controls the horizontal plate 722 to perform an upward movement with a stroke of H1 cm, the first return spring 413 drives the annular cutter group 43 to reset, and the stripping knife group 53 remains stationary in the first annular incision 81.

[0059] S400, use the feed wheel assembly 3 to continue moving the cable 8, and the stripping knife group 53 is used to strip the cable 8 axially. After T1s, the second annular incision 83 on the surface of the cable 8 moves to the position of the cutting knife body 62. At this time, the stripping knife group 53 cuts the stripping incision 82 between the first annular incision 81 and the second annular incision 83, thereby removing or stripping the insulation skin on the surface of the cable 8. The stripped insulation skin is scattered into the fixed shell 12. At the same time, the second telescopic member 721 is used to move the horizontal plate 722 to above the bent rod 61 and the second rack 511. At this time, the first through hole 723 is aligned with the second rack 511. The first telescopic member 711 is used to control the lifting shell 712 and the horizontal plate 722 to move. The lifting motion is H1cm. The cutting blade body 62 that follows the horizontal plate 722 and the curved rod 61 to do the lifting motion is used to cut the cable 8 between the first ring incision 81 and the second ring incision 83, so as to accurately cut off the excess part of the end of the cable 8, and continue to cut the remaining part. The pressure rod 65 that follows the curved rod 61 to do the lifting motion controls the limit rod 542 to separate from the fixed ring 513 by sliding contact with the surface of the pressure rod 543. After the lifting housing 712 and the horizontal plate 722 are controlled to rise and reset by the first telescopic member 711, the elastic force of the second reset spring 514 and the fourth reset spring 64 controls the stripping blade group 53 and the cutting blade body 62 to reset by driving the second rack 511 and the curved rod 61 to rise;

[0060] S500, continue to move the cable 8 using the feed wheel assembly 3, stop the feed wheel assembly 3 after T2s, T2>T1, for accurately controlling the length of the cable 8, complete the first annular incision 81 on the surface of the cable 8 using step S200, cut the second annular incision 83 on the surface of the cable 8 using step S300, and adjust the stripping knife group 53 to the first annular incision 81 and keep it stationary, and cut the cable 8 between the first annular incision 81 and the second annular incision 83 using step S400;

[0061] S600, repeating step S500, not only can the cable 8 be accurately cut into several sections of equal length, but also the two ends of each section of cable 8 can be accurately cut into cable cores of equal length.

[0062] It should be noted that when the cutting machine needs to be used to cut the cable 8 without insulation, it is only necessary to use the second telescopic member 721 to move the horizontal plate 722 to above the bending rod 61 and the second rack 511. Since the first through hole 723 is aligned with the top of the second rack 511 at this time, the first telescopic member 711 can independently control the lifting shell 712, the horizontal plate 722 and the cutting blade 62 to cut the cable 8. In addition, the present application is also suitable for precise cutting of other metal wires.
