Description

Technical Field

[0001] This invention relates to the field of cable manufacturing technology, and more specifically, to a device for separating PVC wrapping tape from cable conductors and its usage method. Background Technology

[0002] In the cable manufacturing process, conductor splicing, terminal crimping, and intermediate joint fabrication are core procedures for ensuring the reliability of cable electrical connections. To tighten and shape the multi-strand stranded conductors and enhance the inner insulation performance, the outer layer of the cable conductor is generally tightly wrapped with PVC wrapping tape in a spiral overlapping manner. This wrapping process typically sets an overlap rate of 30%–50% to ensure tightness and structural stability, but it also directly results in the thickness of the wrapping tape overlap being twice the thickness of the single layer, causing the overall wrapping layer thickness to be periodically uneven along the circumference of the cable.

[0003] Currently, traditional separation devices often use conventional single-blade cutting tools for circumferential cutting when peeling off the ends of PVC wrapping tape. Due to the periodic variations in the thickness of the wrapping tape, a single cut can easily result in excessive cutting depth in a single layer, damaging the internal metal conductor, while the cutting depth in overlapping areas is insufficient, failing to completely cut through. This ultimately leads to incomplete tape peeling, leaving localized residue and preventing effective separation of the wrapping tape from the cable conductor. This directly affects the contact conductivity and mechanical connection strength of subsequent welding and crimping processes.

[0004] Meanwhile, PVC wrapping tape itself has a certain degree of material resilience. After being peeled off, the tape easily wraps back onto the conductor surface or gets stuck in the cutter gaps, causing jamming during the peeling process and tape breakage. This necessitates manual intervention to stop the machine midway for cleaning, severely impacting the automated continuous operation capability of the equipment and restricting the production efficiency and quality stability of cable end processing. Therefore, there is an urgent need for a cable conductor PVC wrapping tape separation device and its usage method to solve the above problems. Summary of the Invention

[0015] A method for separating PVC wrapping tape from cable conductors, applied to the cable conductor PVC wrapping tape separation device described in the above embodiments, includes the following steps: S1: Place the cable conductor with the PVC wrapping tape to be peeled between the two sets of clamps, start the first motor to drive the second threaded screw to rotate, and drive the two clamps to move towards each other along the through groove. The cable conductor is clamped and fixed through the diamond clamping area, so that the cable and the separation cylinder remain coaxial. S2: Start the fourth motor to drive the first threaded screw to rotate, which will move the mounting plate and the entire rotary cutting assembly along the first guide rod axially to the preset peeling start position. Then start the third motor, which will drive all the racks to feed radially synchronously through gear transmission, so that the blades abut against the PVC wrapping tape on the surface of the cable. S3: Start the second motor to drive the separation cylinder to rotate around the cable axis. Multiple sets of blades perform circumferential cutting on the PVC wrapping tape. At the same time, control the third motor to continue rotating at a small angle, drive the blades to feed a second time to cut through the overlapping area of ​​the wrapping tape. At the same time, the linkage push plate pushes the extension block forward, so that the rubber block tightens the wrapping tape. The second rotating column drives the fan blade to generate airflow, which blows away the stripping waste through the air duct. The displacement component feeds axially in sync to complete the stripping of the wrapping tape of the set length. S4: After the stripping is completed, the second and fourth motors stop in sequence, the third motor rotates in the opposite direction to drive the blade to retract radially, the extension block is reset under the action of the spring, and at the same time the fourth motor drives the rotary cutting assembly to return to the initial position in the opposite direction, the first motor rotates in the opposite direction to open the clamp and take out the cable conductor that has been separated from the wrapping tape.

[0016] The beneficial effects of this invention are: This invention provides a cable conductor PVC wrapping tape separation device and method. Through a multi-blade synchronous rotary cutting and secondary micro-feed structure, it can adapt to working conditions with uneven circumferential thickness of the PVC wrapping tape. This effectively solves the problems of overcutting and scratching the conductor in single-layer areas and incomplete cutting through overlapping layers during traditional single-blade cutting. Simultaneously, multiple sets of blades are evenly distributed along the ring and feed synchronously radially, resulting in high consistency in cutting depth. Coaxiality can be guaranteed without individual blade calibration. A single ring cut can form a flat ring-shaped reference cut, and the secondary micro-feed can accurately cut through the double-layer overlapping area, avoiding scratching the internal metal conductor and ensuring complete and residue-free stripping of the wrapping tape, significantly improving the flatness of the cut and the quality of the stripping.

[0017] This invention provides a cable conductor PVC wrapping tape separation device and its usage method. Through the setting of a diamond-shaped clamping component and a follow-up tensioning rubber block structure, it can achieve precise centering and clamping of the cable conductor and tape tensioning protection during the cutting process. The diamond-shaped clamping cavity can adapt to cables with different outer diameters, with high clamping and centering accuracy, ensuring that the cable and the separation cylinder always remain strictly coaxial, thus avoiding the problems of overcutting or incomplete cutting on one side caused by eccentric cutting. At the same time, the rubber block and the blade feed synchronously to press down the tape, which can flatten the tape and prevent it from warping during cutting. During the second feed, they extend synchronously to pull and tension the tape, counteracting the rebound force of the PVC material and preventing the tape from tearing, fraying, or getting stuck in the cutter slit, ensuring a stable and smooth cutting process.

[0018] This invention provides a cable conductor PVC wrapping tape separation device and its usage method. Through the setting of a coaxial linkage air duct blowing structure and axial displacement component, it can realize automatic material removal and continuous operation in the peeling process. That is, the air duct fan blades and the rotary cutting drive shaft are coaxially linked, and a directional airflow can be generated without the need for an additional power source. After being guided by the air duct, the PVC waste material that has been peeled off is blown away in real time, avoiding the waste material from getting stuck on the cutter and conductor surface, eliminating the need for manual shutdown and cleaning. It can also work with the displacement component to drive the rotary cutting mechanism to feed smoothly axially, and can automatically complete the peeling of the wrapping tape of a set length. The whole process has a high degree of automation, effectively improving the production efficiency and quality stability of cable end processing. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0031] Please see Figures 1-9 A cable conductor PVC wrapping tape separation device includes a workbench 1, a clamping assembly on the top of the workbench 1 for ensuring stable separation of the cable conductor 3 surface wrapping tape 4, and a rotary cutting assembly on the top of the workbench 1 for quickly separating the cable conductor 3 surface wrapping tape 4. The top of the worktable 1 is equipped with a displacement component for adjusting the position of the rotary cutting component; The rotary cutting assembly includes a mounting plate 14 mounted on the top of the workbench 1. A second motor 15 is fixedly connected to one outer wall of the mounting plate 14. A second rotating column 43 is fixedly connected to the output end of the second motor 15. A fixed cylinder 19 is fixedly connected to the outer circumference of the second rotating column 43. A rotating disk 11 is fixedly connected to one end of the fixed cylinder 19. Reinforcing columns 12 are evenly spaced and circularly distributed on one outer wall of the rotating disk 11. A separating cylinder 10 is fixedly connected to the other end of the reinforcing columns 12. Blades 39 are evenly spaced and circularly distributed inside the separating cylinder 10. The second motor 15 can drive the second rotating column 43, the rotating disk 11, and the separating cylinder 10 to rotate coaxially. The evenly distributed circular blades 39 inside the separating cylinder 10 synchronously complete the circumferential rotary cutting operation. With the cooperation of the clamping and displacement assembly of the workbench 1, stable and efficient circumferential cutting and separation of PVC wrapping tape of cables can be achieved.

[0032] Furthermore, the clamping assembly includes an adjustment box 5 fixedly connected to the outer wall of the top of the worktable 1. A first motor 6 is fixedly connected to one side of the outer wall of the adjustment box 5. A second threaded screw 21 is fixedly connected to the output end of the first motor 6. A second threaded sleeve 20 is threadedly connected to the outer circumference of the second threaded screw 21. A first sliding column 22 is fixedly connected to the top outer wall of the second threaded sleeve 20. A through groove 8 is provided on the top of the adjustment box 5. A clamping device 7 is fixedly connected to one end of the first sliding column 22 that passes through the through groove 8. The clamping area formed between the two is... The adjustment box 5 is rhomboid in shape. The inner walls of both sides are fixedly connected with second guide posts 24. The outer circumference of the second guide post 24 is slidably connected with a second guide cylinder 23. The second guide cylinder 23 is fixedly connected to the second threaded sleeve 20 through a cross post. The first motor 6 drives the second threaded screw 21 to drive the two sets of clamps 7 to move synchronously in opposite directions. The rhomboid clamping cavity can adapt to cables of different outer diameters. The combination of the second guide post 24 and the second guide cylinder 23 achieves stable limiting and guiding. After clamping, the cable has high coaxiality, which effectively prevents the cable from shifting and eccentric cutting during the stripping process.

[0033] Furthermore, the displacement assembly includes a fourth motor 41 fixedly connected to the inner wall of one side of the control box 2. The output end of the fourth motor 41 is fixedly connected to a first threaded screw 13. The first threaded screw 13 is threadedly connected to one side of the mounting plate 14. The top outer wall of the adjustment box 5 is fixedly connected to a first connecting plate 9. One side outer wall of the first connecting plate 9 is fixedly connected to a first guide rod 16. One end of the first guide rod 16 passes through the other side of the mounting plate 14. The fourth motor 41 drives the first threaded screw 13 to move the mounting plate 14 and the entire rotary cutting assembly smoothly along the first guide rod 16, accurately adjusting the working position of the rotary cutting mechanism. The guide rod can limit the offset of the mounting plate 14, ensuring coaxial and smooth feed movement, and achieving precise and controllable peeling length.

[0034] Furthermore, an annular cover 25 is fixedly connected to the inner circumference of the separating cylinder 10. A third motor 26 is fixedly connected to one outer wall of the annular cover 25. A first rotating column 27 is fixedly connected to the output end of the third motor 26. A driving gear column 28 is fixedly connected to the outer circumference of the first rotating column 27. A gear ring plate 29 and a gear rod 50 are respectively meshed on the outer circumference of the driving gear column 28. The gear rod 50 is located above the gear ring plate 29. A driven gear column 49 is rotatably connected to one inner wall of the annular cover 25. The gear rod 50 and the driven gear column 49 mesh with each other. The driven gear column 49 and another gear rod 50 mesh with each other. The gears mesh with each other. One end of the rack 50 passes through the inside of the annular cover 25. The end of the rack 50 extending to the outer wall of the annular cover 25 is fixedly connected to the second connecting plate 32. The blade 39 is fixedly connected to the outer wall of one side of the second connecting plate 32. The third motor 26 drives the drive gear column 28, which drives multiple racks 50 to move radially synchronously through the gear ring plate 29 and the driven gear column 49. This uniformly drives each second connecting plate 32 and the blade 39 to feed or retract synchronously, ensuring that the cutting depth of all the circumferentially distributed blades 39 is completely consistent, adapting to cables of different diameters and avoiding coaxiality errors caused by single blade adjustment.

[0035] Furthermore, an extension block 40 is provided on one side of the second connecting plate 32, and a second sliding column 37 is inserted into the outer wall of one side of the extension block 40. A second spring 38 is sleeved on the outer circumference of the second sliding column 37. A second rubber block 36 is fixedly connected to one end of the second sliding column 37, and a first rubber block 35 is fixedly connected to the outer wall of one side of the second rubber block 36. The cross-section of the second rubber block 36 is rectangular, and the cross-section of the first rubber block 35 is arc-shaped. The ends of the second rubber block 36 and the first rubber block 35 are both located on the same horizontal plane as the end of the blade 39. The end of the first rotating column 27 extending to the outside of the annular cover 25 is fixedly connected to the first... A first gear disk 30 has a second gear disk 31 meshing with its outer circumference. The diameter of the first gear disk 30 is larger than that of the second gear disk 31. A third threaded screw 44 is fixedly connected to the inner circumference of the second gear disk 31. A third threaded sleeve 45 is threadedly connected to the outer circumference of the third threaded screw 44. A push plate for applying thrust to the extension block 40 is fixedly connected to one side of the outer wall of the third threaded sleeve 45. During the secondary feeding process, the first gear disk 30 at the end of the first rotating column 27 also rotates synchronously with the shaft. The meshing of the large-diameter first gear disk 30 with the small-diameter second gear disk 31... The speed-increasing transmission drives the third threaded screw 44 to rotate synchronously, which in turn drives the third threaded sleeve 45 to move forward axially. The pusher plate pushes the extension block 40 to slide forward along the third guide post 33, causing the second rubber block 36 at the front end of the extension block 40 to extend synchronously with the first rubber block 35. At this time, both the first rubber block 35 and the second rubber block 36 are pressed against the surface of the wrapping tape 4. When subjected to the pushing force of the pusher plate, a tensile force is applied to the single-layer area of ​​the wrapping tape 4 after one circumferential cut. This tensile force eliminates the loose and wrinkled state of the single-layer tape, maintaining a flat and taut cutting condition, allowing the cutting edge of the secondary cut to be subjected to... The force is uniform and stable, avoiding problems such as skewed cuts, tearing, and stringing caused by loose strip material. It further improves the flatness of the cut in the overlapping area. At the same time, the double-layer overlapping structure under tension is more fully stressed, and the blade can cut through the overlapping layer neatly in one go. There will be no situation where the strip material slips with the blade and does not break, ensuring that the peeling of the overlapping area is thorough and without residue. Moreover, the pulling direction is consistent with the peeling feed direction, which can naturally pull and guide the cut strip material to the end side, counteracting the rebound force of the PVC strip material itself. This reduces the probability of the strip material wrapping inward and getting stuck in the blade seam from the root. Combined with the subsequent air duct 17 blowing structure, it further improves the smoothness of material removal.

[0036] Furthermore, a third guide post 33 is fixedly connected to one side of the outer wall of the second connecting plate 32. The extension block 40 is slidably connected to the third guide post 33. A first spring 34 is sleeved on the outer circumference of the third guide post 33 to facilitate the quick reset of the extension block 40. The extension block 40 can slide smoothly along the third guide post 33. After cutting, the first spring 34 can quickly pull the extension block 40 back to reset, releasing the tension constraint of the rubber block on the PVC wrapping tape, without affecting the retraction action of the blade 39. The structure linkage is stable and reliable.

[0037] Furthermore, the outer walls at both ends of the annular cover 25 are fixedly connected to a fourth guide post 47, and the outer circumferential wall of the fourth guide post 47 is slidably connected to a third guide cylinder 48. Another push plate is fixedly connected to one side of the outer wall of the third guide cylinder 48, and the outer walls on both sides of the third guide cylinder 48 are fixedly connected to an arc rod 46. Two adjacent third guide cylinders 48 are fixedly connected to each other through the arc rod 46. The third guide cylinder 48 and the third threaded sleeve 45 are also fixedly connected through the arc rod 46. This allows all push plates to move axially synchronously with the third threaded sleeve 45, ensuring that the feed amount of the extension blocks 40 in all circumferential directions is consistent, so that the tension pressure of the rubber block on the wrapping tape is evenly distributed, and it is precisely coordinated with the radial feed action of the blade 39.

[0038] Furthermore, a duct 17 is fixedly connected to one side of the outer wall of the rotating disk 11. The outer circumference of the duct 17 has evenly spaced, circularly distributed air inlets. Inside the duct 17 is a bushing fixedly connected to one end of the second rotating column 43. A fan blade 42 is fixedly connected to the outer circumference of the bushing. An air guide duct 18 is eccentrically fixed to one end of the duct 17. The clamp 7 is connected to the air guide duct 18. The cross-section of the air guide duct 18 is wavy. The end of the second rotating column 43 is synchronously... The shaft sleeve and fan blade 42 inside the air duct 17 rotate at high speed. Outside air continuously enters the air duct 17 through the air inlet on the side wall of the air duct 17 to form a stable airflow. After the airflow is guided by the eccentrically set wave-shaped air guide duct 18, it is blown in a direction towards the cable stripping operation area, blowing the stripped PVC wrapping tape waste away from the conductor surface and the gap of the blade in real time. The eccentrically set wave-shaped air guide duct 18 can expand the cleaning area of ​​the airflow and avoid the residue of wrapping tape 4 waste in the separation cylinder 10.

[0039] A method for separating PVC wrapping tape from cable conductors, applied to a PVC wrapping tape separation device for cable conductors in the above embodiments, includes the following steps: Step 1: Place the cable conductor with the PVC wrapping tape to be stripped between the two sets of clamps 7, start the first motor 6 to drive the second threaded screw 21 to rotate, and drive the two clamps 7 to move towards each other along the through groove 8, clamping and fixing the cable conductor through the diamond clamping area, so that the cable and the separation cylinder 10 remain coaxial. Step 2: Start the fourth motor 41 to drive the first threaded screw 13 to rotate, which will drive the mounting plate 14 and the entire rotary cutting assembly to move axially along the first guide rod 16 to the preset peeling start position. Then start the third motor 26, which will drive all the racks 50 to feed radially synchronously through gear transmission, so that the blade 39 abuts against the PVC wrapping tape on the surface of the cable. Step 3: Start the second motor 15 to drive the separation cylinder 10 to rotate around the cable axis. Multiple sets of blades 39 perform circumferential cutting on the PVC wrapping tape. At the same time, control the third motor 26 to continue rotating at a small angle, drive the blades 39 to feed a second time to cut through the overlapping area of ​​the wrapping tape. At the same time, the linkage push plate pushes the extension block 40 forward, so that the rubber block tightens the wrapping tape. The second rotating column 43 drives the fan blade 42 to generate airflow, which blows away the stripping waste through the air duct 18. The displacement component feeds axially in sync to complete the stripping of the wrapping tape of the set length. Step 4: After the stripping is completed, the second motor 15 and the fourth motor 41 stop in sequence, the third motor 26 rotates in the opposite direction to drive the blade 39 to retract radially, the extension block 40 is reset under the action of the spring, at the same time the fourth motor 41 drives the rotary cutting assembly to return to the initial position in the opposite direction, the first motor 6 rotates in the opposite direction to make the clamp 7 open, and the cable conductor that has been separated from the wrapping tape is taken out.

[0040] In summary, with the help of the above-mentioned technical solution of the present invention, when in use, the operator first places the cable conductor with the PVC wrapping tape to be stripped on the end in the clamping area between the two sets of clamps 7, and then starts the first motor 6 of the clamping assembly. The first motor 6 drives the second threaded screw 21 to rotate, and drives the two second threaded sleeves 20 to move in opposite directions in a straight line along the screw under the lateral guidance limit of the second guide post 24 and the second guide cylinder 23. Then, through the first sliding post 22, the two clamps 7 move synchronously along the through groove 8 at the top of the adjusting box 5, and finally the cable conductor is stably clamped in the enclosed diamond-shaped clamping cavity. The diamond-shaped clamping structure can adapt to cables with different outer diameters and has high centering accuracy, which can ensure that the cable always keeps strictly coaxial with the separating cylinder 10, effectively avoiding the cable from moving or deflecting radially during the stripping process, thereby avoiding the problems of unilateral overcutting and scratching of the conductor and unilateral incomplete cutting and residual wrapping tape caused by eccentric cutting, and ensuring uniform circumferential cutting depth. After the cable clamping and positioning are completed, the operator starts the fourth motor 41. The fourth motor 41 drives the first threaded screw 13 to rotate at a constant speed, causing the mounting plate 14 and its entire set of rotary cutting components to move smoothly along the first guide rod 16 towards the cable end. After the separating cylinder 10 reaches the preset peeling start position, the fourth motor 41 stops. At this time, the operator starts the third motor 26 to drive the first rotating column 27 to rotate. The first rotating column 27 drives the driving gear column 28 to rotate synchronously. Through the step-by-step meshing transmission between the driving gear column 28, the gear ring plate 29, and multiple sets of driven gear columns 49, all the gear rods 50 are driven to feed radially synchronously towards the center of the cable. Then, through the second connecting plate 32, multiple sets of evenly distributed ring-shaped blades 39 are pushed synchronously towards the cable surface. The synchronous feeding of multiple blades can ensure that the radial cutting depth of each blade 39 is completely consistent, without the need for individual calibration of each blade. It can accurately adapt to cable specifications with different wire diameters and different wrapping tape thicknesses, and also avoids the coaxiality error caused by independent adjustment of a single blade. When the blade 39 moves When the blade 39 moves, the first rubber block 35 and the second rubber block 36 on one side will also move together. After the blade 39 moves to the position of contact with the wrapping tape 4, the first rubber block 35 and the second rubber block 36 will also press lightly against the surface of the PVC wrapping tape on one side of the blade 39. This can flatten the tape and prevent the wrapping tape from lifting and tearing due to cutting force during cutting, ensuring that the cut end face is flat and burr-free. After the position of the blade 39 is adjusted, the second motor 15 is started. The second motor 15 drives the rotating disk 11 to rotate at a constant speed through the second rotating column 43 and the fixed cylinder 19. The rotating disk 11 drives the separation cylinder 10 to rotate coaxially around the cable axis through multiple annularly distributed reinforcing columns 12, so that multiple sets of blades 39 perform a circumferential cut on the PVC wrapping tape. First, a flat annular reference cut perpendicular to the cable axis is cut at the peeling start position. The multiple blades cut circumferentially at the same time with uniform force, and the cut is not skewed or chipped. This provides a regular starting section for subsequent axial peeling and can avoid the problems of tape tearing and edge residue caused by single-sided cutting. Because some areas of the wrapping tape 4 on the conductor surface overlap, the blade 39 cannot cut the entire wrapping tape 4 in one circumferential cut. At this time, the staff restarts the third motor 26 to make a second micro-adjustment to the position of the blade 39. The third motor 26 continues to drive the first rotating column 27 to rotate at a small angle. Through the precise transmission of the driving gear column 28, the gear ring plate 29 and the driven gear column 49, all the gear rods 50 are driven to make a micro-feed radially toward the center of the cable, pushing the blade 39 to cut into the wrapping tape further until the blade depth just penetrates the total thickness of the double-layer overlap area. During the second feeding process, the first gear disk 30 at the end of the first rotating column 27 will also rotate synchronously with the shaft. Through the meshing of the large-diameter first gear disk 30 and the small-diameter second gear disk 31, the speed-increasing transmission is achieved, which drives the third threaded screw 44 to rotate synchronously, thereby driving the third threaded sleeve 45 to move forward axially. Through the push plate, the extension block 40 is pushed to slide forward along the third guide column 33, so that the second rubber block 36 at the front end of the extension block 40 and the first rubber block 35 extend synchronously. At this time, the first rubber block 35 and the second rubber block 36 are pressed against the surface of the wrapping tape 4. When pushed by the push plate, they can apply a pulling force to the single-layer area of ​​the wrapping tape 4 after one ring cut. This pulling force can eliminate the loose and wrinkled state of the single-layer tape, keep the tape flat and taut during the cutting process, and make the blade of the second cut evenly and stably stressed. This avoids the problem of skewed cuts, tearing and stringing caused by loose tape, further improving the flatness of the cut in the overlapping area. At the same time, the double-layer overlapping structure under tension is more fully stressed, and the blade can cut through the overlapping layer neatly in one go. There will be no situation where the tape slips with the blade and is cut but not broken. This ensures that the overlapping area is completely peeled off without residue. Moreover, the pulling direction is consistent with the peeling feed direction, which can pull and guide the cut tape to the end side to counteract the rebound force of the PVC tape itself. This reduces the probability of the tape wrapping back inward and getting stuck in the blade seam from the root. Combined with the subsequent blowing structure of the air duct 17, it further improves the smoothness of the unloading. At the same time, the end of the second rotating column 43 synchronously drives the bushing and fan blade 42 inside the air duct 17 to rotate at high speed. Outside air continuously enters the air duct 17 from the air inlet on the side wall of the air duct 17 to form a stable airflow. After the airflow is guided by the eccentrically set wave-shaped air guide pipe 18, it is blown in a direction to the cable stripping operation area, and blows the stripped PVC wrapping tape waste away from the conductor surface and the gap of the tool in real time. After the axial feed reaches the preset stripping length, the fourth motor 41 and the second motor 15 stop operating in sequence, and the third motor 26 rotates in the opposite direction. Through the gear transmission system, all the racks 50 are driven to retract radially in sync. The blade 39 and the rubber block retract radially in sync and detach from the conductor surface. The extension block 40 is reset synchronously under the rebound action of the first spring 34 on the third guide post 33. Then, the fourth motor 41 drives the first threaded screw 13 to rotate in the opposite direction, driving the entire rotary cutting assembly to retract to the initial standby position along the first guide rod 16. The first motor 6 of the clamping assembly rotates in the opposite direction, driving the two sets of second threaded sleeves 20 to move in opposite directions, driving the two clamps 7 to open synchronously. The operator can then take out the cable conductor with the PVC wrapping tape separated at the end and directly proceed to the subsequent welding or crimping process.
