Description

Technical Field

[0001] This invention belongs to the technical field of circumferential cutting equipment, specifically a circumferential cutting device for cable processing and its working method. Background Technology

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information, and realize the conversion of electromagnetic energy. In a broad sense, wires and cables are also simply referred to as cables. In a narrow sense, a cable refers to an insulated cable, which can be defined as: an assembly consisting of one or more insulated conductors, and their respective possible covering layers, overall protective layer, and outer sheath. Cables may also have additional uninsulated conductors. For cable processing, it is usually necessary to circumferentially cut the insulation layer on the outer surface of the cable to expose the internal wires and facilitate subsequent cable connection and other processing.

[0003] Existing cable circumferential cutting devices typically involve fixing the cable securely and then using two sets of cutting blades distributed front and back to approach and contact the cable. As the cable rotates, the approaching blades create a circumferential cut. However, in practice, this process is cumbersome due to the need for constant cable rotation and the need to adjust the movement of the two sets of cutting blades. It requires frequent and repetitive operations, and the processing time is long when circumferentially cutting multiple points on the cable, resulting in low efficiency and poor performance.

[0004] Furthermore, in the existing cable processing circumferential cutting device, after completing the circumferential cutting of a set of cable insulation jackets, when it is necessary to separate the circumferentially cut insulation jackets, manual peeling is usually used. The actual peeling process is quite laborious. When the length of the circumferentially cut insulation jacket is long, the frictional resistance in the actual peeling process is large, making it too difficult to separate the circumferentially cut insulation jackets and resulting in poor peeling effect. Summary of the Invention

[0005] The purpose of this invention is to provide a circumferential cutting device for cable processing and its working method, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a circumferential cutting device for cable processing and its working method, comprising a base, a vertical plate fixedly connected to the top surface of the base, a clamping rod threadedly sleeved on the top surface of the vertical plate, two vertical plates, a cable sleeved between the two vertical plates, a movable mechanism movably mounted on the top surface of the base, a mounting ring fixedly connected to the top surface of the movable mechanism, an annular cavity formed inside the mounting ring, a movable ring movably sleeved on the inner surface of the annular cavity, a communicating sleeve fixedly connected to the inner surface of the movable ring, a push plate movably sleeved on the inner surface of the communicating sleeve, a sleeve rod fixedly connected to the outer side of the push plate, and the outer end face of the sleeve rod... A cutter holder is fixedly connected, and a ring cutter is fixedly installed on the end face of the cutter holder. One end of a No. 1 spring is fixedly connected to the inner side of the push plate, and the other end of the No. 1 spring is fixedly connected to a movable ring. A power mechanism is fixedly installed on the top surface of the mounting ring. A fixed ring is fixedly installed on the side of the movable ring. A No. 1 gear is fixedly sleeved on the outer surface of the fixed ring, and the No. 1 gear meshes with the power mechanism. An inner cavity is opened inside the movable ring, and a side groove is opened on the outer surface of the movable ring, which communicates with the inner cavity. A control mechanism and an oil tank are provided on the top surface of the movable mechanism. The control mechanism is connected to the mounting ring, and an intermediate pipe is fixedly connected between the control mechanism and the oil tank.

[0007] Furthermore, by fixing and keeping the cable horizontal, and adjusting the actual circumferential cutting position during the actual circumferential cutting, and further adjusting the required circumferential cutting length after adjustment, convenient circumferential cutting at the fixed cable location is achieved through the movable installation of the movable mechanism and the base. Convenient circumferential cutting adjustment is achieved for different circumferential cutting requirements. Combined with the convenience of rotating the circumferential cutter, it has good adaptability for circumferential cutting of multiple sets of cables and multiple circumferential cutting of a single set of cables. Moreover, through the effect of symmetrical hydraulic extrusion, different circumferential cutting depths are adjustable for cable insulation jackets of different diameters, resulting in higher actual circumferential cutting accuracy and better performance.

[0008] Preferably, the power mechanism includes a support ring, a mounting bracket, a motor, and a second gear. The support ring is fixedly connected to the side of the mounting ring, the mounting bracket is fixedly mounted on the top surface of the support ring, the motor is fixedly mounted inside the mounting bracket, and the second gear is fixedly sleeved on the motor shaft. The second gear meshes with the first gear. By utilizing the motor in the power mechanism to provide rotational power, and cooperating with the meshing of the first and second gears, the movable ring is rotated, thereby causing the ring cutters on both sides to rotate and perform ring cutting.

[0009] Preferably, the movable mechanism includes a movable plate, a support plate, a sleeve plate, and a locking plate. The movable plate is located above the base. The support plate is fixedly installed on the top surface of the movable plate and is fixedly sleeved with the mounting ring. The sleeve plate is fixedly connected to the bottom surface of the movable plate. The locking plate is fixedly connected to the side of the sleeve plate. By using the movable mechanism to support the mounting ring and the power mechanism, stable movement and adjustment along the top surface of the base can be achieved, facilitating the switching of the ring cutting position.

[0010] Preferably, the control mechanism includes an oil pump, a control valve, and a curved pipe. The control valve is fixedly connected to the output end of the oil pump. The oil pump is fixedly mounted on the top surface of the movable plate. The curved pipe is fixedly connected between the control valve and the mounting ring. The input end of the oil pump is fixedly connected to the intermediate pipe. The control mechanism draws pressurized oil from the oil tank and feeds the pressurized oil into the mounting ring through the control valve and the curved pipes on both sides. The pressurization method drives the movement of the ring cutter, thereby controlling the movement of the ring cutter and thus controlling the actual ring cutting depth.

[0011] Preferably, the end face of the connecting sleeve is provided with a sleeve hole, the inner diameter of the sleeve hole is smaller than the diameter of the push plate, and the inner surface of the sleeve hole is movably sleeved with the sleeve rod. By controlling the size of the sleeve hole and the push plate, the push plate, whose diameter is slightly smaller than the inner diameter of the connecting sleeve, has good sealing and limiting when moving, ensuring that there is no leakage when the pressure oil is introduced.

[0012] Preferably, the top surface of the upright plate is provided with a threaded hole, and the inner surface of the threaded hole is threadedly connected to the clamping rod. By utilizing the threaded hole, the threaded clamping rod can clamp and fix the cable, ensuring good stability during circumferential cutting.

[0013] Preferably, the top surface of the base is provided with a movable groove, and the side of the movable groove is provided with a connected slot. The inner surface of the movable groove is movably sleeved with the sleeve plate, and the inner surface of the slot is movably sleeved with the slot plate. By utilizing the movable sleeve of the slot and the slot plate, the movable mechanism can be stably slid along the top surface of the base.

[0014] Preferably, a dividing mechanism is fixedly installed on the inner side of one of the upright plates. The dividing mechanism is located above the cable and is used to separate and peel off the cable insulation sleeve after circumferential cutting.

[0015] Preferably, the dividing mechanism includes a side plate, a movable rod, a dividing blade, a top plate, and a second spring. The side plate is fixedly connected to the side of the upright plate, the movable rod is movably sleeved inside the side plate, the dividing blade is fixedly installed on the bottom surface of the movable rod, the top plate is fixedly connected to the top surface of the movable rod, and the second spring is fixedly connected between the top plate and the side plate. By using the downward dividing mechanism, the dividing blade is inserted into the annular groove formed at the circumferential cutting point, and the separation of the cable insulation sleeve after circumferential cutting is completed during the pulling of the cable, improving the ease of peeling. Furthermore, the second spring facilitates quick reset after the downward pressure is released.

[0016] A method for operating a circumferential cutting device for cable processing includes the following steps: Step 1: Connect the cable between the two sets of upright plates, and when connecting, make sure that one end of the cable passes through the mounting ring. Then, tighten the clamping rod by turning it down to press the cable. Push the movable mechanism to move the mounting ring to the position to be ring cut, and start the control mechanism to pump the oil from the oil tank into the ring cavity of the mounting ring. The pressurized oil enters the connecting sleeve through the movable ring and pushes the ring cutters on both sides to cut the insulation sleeve of the cable. Then, start the power mechanism to complete the rotation ring cut. Step 2: After this circumferential cutting is completed, according to the actual length of the cable insulation jacket to be cut, push the movable mechanism to move the installation ring to another circumferential cutting point, and start the control mechanism and power mechanism to complete the circumferential cutting on the other side, so as to realize the circumferential cutting of the entire cable insulation jacket. Step 3: After completing a set of ring cuts, pull the cable while it is under the pressure of the upper clamping rod, so that the ring cut point moves to the bottom of the cutting mechanism. Press down on the cutting mechanism so that the cutting blade in the cutting mechanism is inserted into the ring cut groove. Keep pressing and continue to pull the cable so that the ring cut insulation jacket on the cable is separated from the top. Pull the insulation jacket down to complete the stripping after ring cut.

[0017] The beneficial effects of this invention are as follows: 1. This invention utilizes a movable mechanism to install an mounting ring, allowing the cable to be circumcised to pass through the mounting ring and be fixed to the upright plates on both sides. While maintaining the cable's horizontal stability, the control mechanism on the movable mechanism is activated, using hydraulic pressure to simultaneously push the circumcising blades on both sides of the cable to a certain depth. After the cut is made, the power mechanism drives the movable ring to rotate, enabling the circumcising blades on both sides to rotate and circumcise along the cable. In practice, after the cable is fixed, it can quickly achieve precise and stable circumcising, greatly improving the actual circumcising effect and efficiency. The actual circumcising process requires fewer operations, reducing the difficulty of circumcising the cable while improving its convenience, resulting in good performance.

[0018] 2. This invention fixes and keeps the cable horizontal, and during actual circumferential cutting, it allows for sliding adjustment based on the actual circumferential cutting position. After adjustment, further adjustments are made according to the required circumferential cutting length. Utilizing the movable installation of the movable mechanism and the base, convenient circumferential cutting at the fixed cable location is achieved. It enables convenient circumferential cutting adjustment for different requirements. Combined with the convenience of rotational circumferential cutting, it has good adaptability for circumferential cutting of multiple sets of cables and multiple circumferential cutting of a single set of cables. Furthermore, through the effect of symmetrical hydraulic extrusion, it allows for adjustment of different circumferential cutting depths for cable insulation jackets of different diameters, resulting in higher actual circumferential cutting accuracy and better performance.

[0019] 3. This invention utilizes a transverse dividing blade in the dividing mechanism. After circumferentially cutting the cable insulation sleeve, the position of the circumferential cut is adjusted by pulling the cable, so that the circumferential groove formed is located below the dividing blade. Pressing the top plate compresses the second spring, causing the dividing blade to insert into the circumferential groove. While maintaining the downward pressure of the dividing mechanism, the cable is pulled outward, causing the top of the circumferentially cut cable insulation sleeve to split open. This allows the cable insulation sleeve to be pulled out from below, facilitating the peeling after circumferential cutting and making the operation convenient. Attached Figure Description

[0022] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1 to 8 As shown, this embodiment of the invention provides a circumferential cutting device for cable processing and its working method, including a base 1, a vertical plate 2 fixedly connected to the top surface of the base 1, a clamping rod 4 threadedly sleeved on the top surface of the vertical plate 2, two vertical plates 2, a cable 3 sleeved between the two vertical plates 2, a movable mechanism 5 movably mounted on the top surface of the base 1, an installation ring 6 fixedly connected to the top surface of the movable mechanism 5, an annular cavity 7 opened inside the installation ring 6, a movable ring 8 movably sleeved on the inner surface of the annular cavity 7, a connecting sleeve 9 fixedly connected to the inner surface of the movable ring 8, a push plate 25 movably sleeved on the inner surface of the connecting sleeve 9, a sleeve rod 11 fixedly connected to the outer side of the push plate 25, a tool holder 12 fixedly connected to the outer end face of the sleeve rod 11, and a tool holder 12... A ring cutter 13 is fixedly installed on the end face. One end of a spring 14 is fixedly connected to the inner side of the push plate 25. The other end of the spring 14 is fixedly connected to the movable ring 8. A power mechanism 19 is fixedly installed on the top surface of the mounting ring 6. A fixed ring 17 is fixedly installed on the side of the movable ring 8. A gear 18 is fixedly sleeved on the outer surface of the fixed ring 17. The gear 18 meshes with the power mechanism 19. An inner cavity 15 is opened inside the movable ring 8. A side groove 16 is opened on the outer surface of the movable ring 8. The side groove 16 communicates with the inner cavity 15. A control mechanism 20 and an oil tank 26 are provided on the top surface of the movable mechanism 5. The control mechanism 20 is connected to the mounting ring 6. An intermediate pipe 27 is fixedly connected between the control mechanism 20 and the oil tank 26.

[0024] First embodiment: as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, cable 3 is sleeved between the two sets of upright plates 2, and when sleeved, one end of cable 3 passes through the mounting ring 6. The clamping rod 4 is screwed down to press the cable 3, pushing the movable mechanism 5, so that the mounting ring 6 moves along the movable groove 22 to the position to be ring-cut, and the control mechanism 20 is activated, so that the control mechanism 20 pumps the oil from the oil tank 26 to the curved pipe 203 through the intermediate pipe 27, and then delivers it to the annular cavity 7 of the mounting ring 6 through the curved pipe 203. The pressurized oil entering the annular cavity 7 enters the inner cavity 15 of the movable ring 8 through the side groove 16 on the side of the movable ring 8, so that the pressurized oil enters the two sets of connecting sleeves 9 from both sides through the inner cavity 15, and pushes the push plate 25 in the two connecting sleeves 9 to move. With the stretching of the first spring 14, the sleeve rod 11 slides and drives the ring-cutting blade 13 to move. This causes the circumferential cutting blades 13 on both sides to cut open the side of the insulation sheath of the cable 3 from both sides. Then, the power mechanism 19 is activated, which drives the second gear 194 to rotate through the motor 193, thereby causing the meshing first gear 18 to rotate. This, in turn, drives the movable ring 8 to rotate through the fixed ring 17, causing the circumferential cutting blades 13 on both sides to rotate and cut along the outer insulation sheath of the cable 3, completing the rotational circumferential cutting. After this circumferential cutting is completed, according to the actual length of the insulation sheath of the cable 3 to be removed, the movable mechanism 5 is pushed, causing the sleeve plate 53 in the movable mechanism 5 to move along the movable groove 22, so that the mounting ring 6 moves to another target circumferential cutting point. Then, the control mechanism 20 and the power mechanism 19 are activated to complete the circumferential cutting on the other side again, realizing the circumferential cutting of the insulation sheath of the entire cable 3.

[0025] First, by using the mounting ring 6 installed by the movable mechanism 5, the cable 3 to be circumcised is fixed to the upright plates 2 on both sides after passing through the mounting ring 6. While keeping the cable 3 horizontal and stable, the control mechanism 20 on the movable mechanism 5 is activated. The hydraulic pressure simultaneously pushes the circumcising blades 13 on both sides of the cable 3 to cut to a certain depth. After the cut is made, the power mechanism 19 drives the movable ring 8 to rotate, so that the circumcising blades 13 on both sides rotate and circumcise along the cable 3. In practice, after the cable 3 is fixed, a fast, accurate and stable circumcising can be achieved, which greatly improves the actual circumcising effect and efficiency of the cable 3. The actual operation in the circumcising process is less, which reduces the difficulty of circumcising the cable 3 and improves the convenience of circumcising the cable 3. The effect of use is good.

[0026] Furthermore, by fixing and keeping the cable 3 horizontal, and adjusting it according to the actual circumferential cutting position during actual circumferential cutting, and further adjusting it according to the required circumferential cutting length after adjustment, convenient circumferential cutting at the fixed cable 3 can be achieved by utilizing the movable installation of the movable mechanism 5 and the base 1. Convenient circumferential cutting adjustment can be achieved for different circumferential cutting requirements. Combined with the convenience of rotating circumferential cutting, it has good adaptability for circumferential cutting of multiple sets of cables 3 and multiple circumferential cutting of a set of cables 3. Moreover, through the effect of hydraulic symmetrical extrusion, different circumferential cutting depths can be adjusted for cable insulation jackets of different diameters, resulting in higher actual circumferential cutting accuracy and better performance.

[0027] The power mechanism 19 includes a support ring 191, a mounting bracket 192, a motor 193, and a second gear 194. The support ring 191 is fixedly connected to the side of the mounting ring 6. The mounting bracket 192 is fixedly installed on the top surface of the support ring 191. The motor 193 is fixedly installed inside the mounting bracket 192. The second gear 194 is fixedly sleeved on the rotating shaft of the motor 193. The second gear 194 meshes with the first gear 18. By using the motor 193 in the power mechanism 19 to provide rotational power, and cooperating with the meshing of the first gear 18 and the second gear 194, the movable ring 8 is rotated, thereby causing the ring cutters 13 on both sides to rotate and perform ring cutting.

[0028] The movable mechanism 5 includes a movable plate 51, a support plate 52, a sleeve plate 53, and a locking plate 54. The movable plate 51 is located above the base 1. The support plate 52 is fixedly installed on the top surface of the movable plate 51 and is fixedly sleeved with the mounting ring 6. The sleeve plate 53 is fixedly connected to the bottom surface of the movable plate 51, and the locking plate 54 is fixedly connected to the side of the sleeve plate 53. By using the movable mechanism 5 to support the mounting ring 6 and the power mechanism 19, stable movement and adjustment along the top surface of the base 1 can be achieved, making it convenient to switch the ring cutting position.

[0029] The control mechanism 20 includes an oil pump 201, a control valve 202, and a curved pipe 203. The control valve 202 is fixedly connected to the output end of the oil pump 201. The oil pump 201 is fixedly mounted on the top surface of the movable plate 51. The curved pipe 203 is fixedly connected between the control valve 202 and the mounting ring 6. The input end of the oil pump 201 is fixedly connected to the intermediate pipe 27. The control mechanism 20 draws pressure oil from the oil tank 26 and feeds the pressure oil into the mounting ring 6 through the control valve 202 and the curved pipes 203 on both sides. The pressure is used to drive the movement of the ring cutter 13, thereby controlling the movement of the ring cutter 13 and thus controlling the actual ring cutting depth.

[0030] The end face of the connecting sleeve 9 is provided with a sleeve hole 10. The inner diameter of the sleeve hole 10 is smaller than the diameter of the push plate 25. The inner surface of the sleeve hole 10 is movably sleeved with the sleeve rod 11. By controlling the size of the sleeve hole 10 and the push plate 25, the push plate 25, whose diameter is slightly smaller than the inner diameter of the connecting sleeve 9, has good sealing and limiting when moving, ensuring that there is no leakage when the pressure oil is introduced.

[0031] The top surface of the upright plate 2 is provided with a threaded hole 24. The inner surface of the threaded hole 24 is threadedly connected to the clamping rod 4. By using the threaded hole 24, the threaded clamping rod 4 can clamp and fix the connected cable 3, ensuring good stability during circumferential cutting.

[0032] The base 1 has a movable groove 22 on its top surface and a connected slot 23 on its side. The inner surface of the movable groove 22 is movably connected to the sleeve plate 53, and the inner surface of the slot 23 is movably connected to the slot plate 54. By utilizing the movable connection between the slot 23 and the slot plate 54, the movable mechanism 5 can be stably slid along the top surface of the base 1.

[0033] Among them, a dividing mechanism 21 is fixedly installed on the inner side of one of the upright plates 2. The dividing mechanism 21 is located above the cable. The cable insulation sleeve is separated and peeled off after circumferential cutting by using the dividing mechanism 21.

[0034] The dividing mechanism 21 includes a side plate 211, a movable rod 212, a dividing blade 213, a top plate 214, and a second spring 215. The side plate 211 is fixedly connected to the side of the upright plate 2. The movable rod 212 is movably sleeved inside the side plate 211. The dividing blade 213 is fixedly installed on the bottom surface of the movable rod 212. The top plate 214 is fixedly connected to the top surface of the movable rod 212. The second spring 215 is fixedly connected between the top plate 214 and the side plate 211. By using the downward dividing mechanism 21, the dividing blade 213 is inserted into the annular groove formed at the circumferential cutting point. During the pulling of the cable 3, the separation of the cable insulation sleeve after circumferential cutting is completed, improving the ease of peeling. The second spring 215 facilitates quick reset after the downward pressure is released.

[0035] Second embodiment: as follows Figure 1 , Figure 2 , Figure 3 and Figure 8As shown, after a set of ring cuts is completed, the cable 3 is pulled while bearing the pressure of the upper clamping rod 4, causing the ring cut to move to the bottom of the dividing mechanism 21. The top plate 214 in the dividing mechanism 21 is pressed down, so that the second spring 215 is kept compressed, and the movable rod 212 moves down, causing the dividing blade 213 in the dividing mechanism 21 to be inserted into the ring groove formed after the ring cut. The dividing mechanism 21 is pressed down and the cable 3 is pulled, so that the insulation jacket cut on the cable 3 is separated from the top along the dividing blade 213. The insulation jacket is pulled down and the stripping after the ring cut is completed.

[0036] First, after the cable insulation sleeve is circumcised by the transverse dividing blade 213 in the dividing mechanism 21, the position of the circumcised section is adjusted by pulling the cable 3 so that the circumcised groove is located below the dividing blade 213. Then, the top plate 214 is pressed, which compresses the second spring 215 and inserts the dividing blade 213 into the circumcised groove. While keeping the dividing mechanism 21 pressed down, the cable 3 is pulled outward, which causes the top of the circumcised cable insulation sleeve to split open, allowing the cable insulation sleeve to be pulled out from below. This makes the stripping after circumcising convenient and easy to operate.

[0037] A method for operating a circumferential cutting device for cable processing includes the following steps: Step 1: Connect cable 3 between the two sets of upright plates 2, and when connecting, make one end of cable 3 pass through the mounting ring 6, and tighten cable 3 by rotating the clamping rod 4 downwards. Push the movable mechanism 5 to move the mounting ring 6 to the position to be circumcised, and start the control mechanism 20 to pump the oil from the oil tank 26 into the annular cavity 7 of the mounting ring 6. The pressurized oil enters the connecting sleeve 9 through the movable ring 8 and pushes the two side circumcised blades 13 to cut the insulation sleeve of cable 3. Then start the power mechanism 19 to complete the rotation circumcised. Step 2: After this circumferential cutting is completed, according to the actual length of the cable 3 insulation jacket to be cut, push the movable mechanism 5 so that the mounting ring 6 moves to another circumferential cutting point, and start the control mechanism 20 and the power mechanism 19 to complete the circumferential cutting on the other side, so as to realize the circumferential cutting of the entire group of cable 3 insulation jackets. Step 3: After completing a set of ring cuts, pull the cable 3 while it is under the pressure of the upper clamping rod 4, so that the ring cut point moves to the bottom of the dividing mechanism 21, and press down on the dividing mechanism 21 so that the dividing blade 213 in the dividing mechanism 21 is inserted into the ring cut groove. Keep pressing and continue to pull the cable 3 so that the ring cut insulation jacket on the cable 3 is separated from the top, and the insulation jacket is pulled out downwards to complete the stripping after ring cut.
