Description

Technical Field

[0001] This invention relates to a double-twist cable forming machine, belonging to the field of cable forming machine technology. Background Technology

[0002] With the rapid development of my country's power construction, the wire and cable industry has also experienced rapid growth, with its demand continuing to increase. Cable production involves pulling different cables onto a stranding structure and then stranding them. Currently, some cable-forming machines lack an effective tension adjustment structure when pulling the cable onto the stranding line. As the cable passes through the stranding line, insufficient tension can easily occur. Conventional cable-forming machines cannot flexibly change the cable tension according to actual tension requirements, causing the cable to be in a slack state during the cable-forming process. This makes it impossible to achieve effective and stable stranding in subsequent stranding, affecting the stability of the cable quality. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a double-twist cable forming machine, which solves the problem that the existing forming machine cannot flexibly change the tension of the cable according to the actual tension requirements, which makes the cable easy to be in a loose state during the forming process, and cannot achieve effective and stable stranding in the subsequent stranding, thus affecting the stability of the forming quality.

[0004] The technical problem to be solved by the present invention is achieved by the following technical solution: A double-twist cable forming machine includes a base, a fixing block fixedly mounted on the base, a first mounting plate disposed on one side of the fixing block, a cable cradle rotatably mounted on one side of the first mounting plate, a first inlet hole penetrating the cable cradle, a second mounting plate disposed on one side of the cable cradle, a second inlet hole penetrating the second mounting plate, a traction plate disposed on one side of the second mounting plate, a traction hole penetrating the traction plate, and a main shaft rotatably mounted on the base, passing through the first and second mounting plates, and the main shaft is fixed to the first and second mounting plates. The main shaft is equipped with a fixed shaft at one end, which is fixedly mounted to the traction disc. The base is equipped with a drive structure for driving the main shaft and the cable cradle basket. The traction disc has two sliding grooves extending radially along the fixed shaft. Sliding plates are slidably mounted inside the two sliding grooves. A tensioning shaft is rotatably mounted between the sliding plates. The fixed shaft has a connecting groove. A connecting rod is fixedly mounted at the end of the sliding plate facing the fixed shaft. The end of the connecting rod away from the sliding plate extends into the connecting groove. The fixed shaft is equipped with a push structure for pushing the connecting rod. A first spring is fixedly mounted between the side of the sliding plate facing the fixed shaft and the inner wall of the sliding groove.

[0005] By adopting the above technical solution, the base is first placed in a suitable position so that the cable cradle can complete the cable loading. Then, one end of the cable is passed through the first inlet hole on the cable cradle and the second inlet hole on the second mounting plate in sequence. Subsequently, the cable is passed between the tensioning shafts and finally led out through the traction hole on the traction plate. When the cable tension is insufficient after passing through the traction hole, the connecting rod is moved inside the connecting groove by the pushing structure. The connecting rod pushes the sliding plate to slide inside the sliding groove. During the sliding process, the sliding plate compresses the first spring. Simultaneously, the sliding plate drives the tensioning shaft to move, so that the tensioning shaft drives the cable to be tensioned. This achieves effective adjustment of the cable tension, ensures that the cable maintains a suitable tension during the cabling process, and improves the cabling quality.

[0006] The present invention is further configured such that: the drive structure includes a motor, a first rotating shaft, a driving wheel, a driven wheel, and a second rotating shaft; the motor is fixedly mounted on the base; the first rotating shaft is poweredly connected to the motor; one end of the first rotating shaft away from the motor extends toward the first mounting plate and is fixedly mounted to the main shaft; the driving wheel is sleeved on the outer surface of the main shaft; the driven wheel is rotatably mounted on the side of the first mounting plate away from the cable cradle basket; the driving wheel meshes with the driven wheel; the second rotating shaft is fixedly connected to the driven wheel; one end of the second rotating shaft passes through the first mounting plate and is fixedly connected to the cable cradle basket.

[0007] By adopting the above technical solution, the starting motor drives the first rotating shaft to rotate, which in turn drives the main shaft to move. The main shaft drives the first mounting plate and the second mounting plate to rotate. At the same time, the main shaft drives the driving wheel to rotate. Under the action of the meshing structure, the driving wheel drives the driven wheel to rotate. Then, the driven wheel drives the second rotating shaft to rotate, which in turn drives the cable cradle basket to move.

[0008] The present invention is further configured such that: the pushing structure includes a first adjusting rod, a rotating block, a connecting block, an adjusting block and an assembly plate, the connecting block is slidably disposed inside the connecting groove, the first adjusting rod is rotatably disposed on the fixed shaft, one end of the first adjusting rod extends into the interior of the connecting groove and is threadedly connected to the connecting block, the adjusting block is disposed on the connecting block and can abut against the connecting rod, the other end of the first adjusting rod extends to the outside of the fixed shaft and is fixedly connected to the rotating block, and the assembly plate is fixedly disposed at the end of the first adjusting rod located inside the connecting groove.

[0009] The present invention is further configured such that: a guide groove is provided on the connecting block, a guide block is slidably disposed inside the guide groove, one end of the guide block extends to the outside of the guide groove and is fixedly connected to the adjusting block, a second adjusting rod is rotatably disposed on the connecting block, one end of the second adjusting rod extends to the inside of the guide groove and is threadedly connected to the guide block, the other end of the second adjusting rod passes through the connecting block and extends to the outside of the fixed shaft, and the second adjusting rod can slide against the fixed shaft.

[0010] By adopting the above technical solution, the rotating block drives the first adjusting rod to rotate. Under the action of the threaded structure, the first adjusting rod drives the connecting block to slide inside the connecting groove, so that the connecting block moves in the direction of the connecting rod. At the same time, the connecting block drives the adjusting block to move. When the adjusting block abuts against the connecting rod, the connecting rod can be moved by the adjusting block.

[0011] The present invention is further configured such that: a limiting groove is formed inside the connecting groove, and a limiting block is fixedly provided at one end of the adjusting block away from the connecting block, and the limiting block is slidably connected to the limiting groove.

[0012] By adopting the above technical solution, the adjusting block will simultaneously drive the limiting block to slide in the limiting groove when it moves. Through the cooperation between the limiting block and the limiting groove, the adjusting block is prevented from shifting when it moves.

[0013] The invention is further configured such that: a circular groove communicating with a connecting groove is provided on a fixed shaft; a threaded rod is provided on one side of the fixed shaft; one end of the threaded rod extends into the interior of the circular groove and is fixedly provided with a disc; the disc is slidably connected to the inner wall of the circular groove; a threaded hole is provided at one end of the main shaft facing the fixed shaft; and the end of the threaded rod away from the fixed shaft extends into the interior of the threaded hole and is threadedly connected to the threaded hole.

[0014] The invention is further configured such that: a slot is provided at the end of the assembly plate away from the first adjusting rod; an inner groove is provided on the disc; a push plate is slidably arranged inside the inner groove; a locking block is fixedly provided at one end of the push plate; the end of the locking block away from the push plate can extend to the outside of the disc and be inserted into the slot; a telescopic rod is fixedly provided between the end of the push plate away from the locking block and the inner wall of the inner groove; a second spring is sleeved on the outside of the telescopic rod; and the two ends of the second spring are fixedly connected to the inner wall of the inner groove and the push plate, respectively.

[0015] The invention is further configured such that: an installation channel communicating with the connecting groove is provided on the fixed shaft, a baffle is provided inside the installation channel, one end of the baffle can abut against the locking block, and a lever is fixedly provided on the outer surface of the baffle, one end of the lever extending to the outside of the fixed shaft.

[0016] By adopting the above technical solution, pulling the lever moves the baffle away from the fixed shaft within the installation channel, separating the baffle from the fixed shaft. This cancels the baffle's contact limit on the locking block. At this time, the second spring resets and pushes the push plate to slide within the inner groove, causing the push plate to move the locking block towards the slot. As the push plate moves, it simultaneously moves the telescopic rod, allowing the locking block to insert into the slot, thus completing the locking limit on the disc. Then, rotating the fixed shaft, under the locking action of the locking block and the slot, synchronously drives the disc to rotate, causing the disc to drive the threaded rod to rotate. Under the action of the threaded structure, the threaded rod moves away from the main shaft, achieving separation of the fixed shaft from the main shaft, thereby disassembling the traction disc. When dealing with cables of different diameters, a suitable traction disc can be replaced according to actual needs, thereby better meeting the cabling requirements of cables of different diameters and improving the equipment's adaptability to diverse cable processing.

[0017] The invention is further configured such that: a threaded rod has an insertion hole, and the main shaft has an insertion channel communicating with the threaded hole; an insertion rod is slidably disposed inside the insertion channel; one end of the insertion rod can extend into the inside of the threaded hole and be inserted into the insertion hole; and the other end of the insertion rod extends to the outside of the main shaft.

[0018] The beneficial effects of this invention are as follows: First, the base is placed in a suitable position so that the cable cradle completes the cable loading. Then, one end of the cable passes through the first inlet hole on the cable cradle and the second inlet hole on the second mounting plate in sequence. Subsequently, the cable is passed between the tensioning shafts and finally led out through the traction hole on the traction plate. When the cable passes through the traction hole and the tension is insufficient, the connecting rod is moved inside the connecting groove by the pushing structure. The connecting rod pushes the sliding plate to slide inside the sliding groove. During the sliding process, the sliding plate compresses the first spring. Simultaneously, the sliding plate drives the tensioning shaft to move, so that the tensioning shaft drives the cable to be tensioned. This achieves effective adjustment of the cable tension, ensuring that the cable maintains a suitable tension during the cabling process and improving the cabling quality.

[0033] like Figure 2 As shown, the drive structure includes a motor 1011, a first rotating shaft 1012, a drive wheel 1013, a driven wheel 1014, and a second rotating shaft 1015. The motor 1011 is fixedly mounted on the base 1 and is connected to an external power source, which provides power to the motor 1011. The first rotating shaft 1012 is poweredly connected to the motor 1011.

The drive wheel 1013 is sleeved on the outer surface of the main shaft 10. The driven wheel 1014 is rotatably mounted on the side of the first mounting plate 3 away from the cable cradle 4. The drive wheel 1013 meshes with the driven wheel 1014. The second rotating shaft 1015 is fixedly connected to the driven wheel 1014. One end of the second rotating shaft 1015 passes through the first mounting plate 3 and is fixedly connected to the cable cradle 4.

[0034] like Figure 4 , Figure 5 and Figure 7 As shown, the pushing structure includes a first adjusting rod 1021, a rotating block 1022, a connecting block 1023, an adjusting block 1024, and an assembly plate 1025. The connecting block 1023 is slidably disposed inside the connecting groove 15. The first adjusting rod 1021 is rotatably disposed on the fixed shaft 11. One end of the first adjusting rod 1021 extends into the interior of the connecting groove 15 and is threadedly connected to the connecting block 1023. The adjusting block 1024 is disposed on the connecting block 1023 and can abut against the connecting rod 16. The other end of the first adjusting rod 1021 extends to the outside of the fixed shaft 11 and is fixedly connected to the rotating block 1022. The assembly plate 1025 is fixedly disposed at one end of the first adjusting rod 1021 located inside the connecting groove 15. A guide groove 1031 is provided on the connecting block 1023. The opening direction of the guide groove 1031 is the same as that of the connecting groove 15. A guide block 1032 is slidably arranged inside the guide groove 1031. One end of the guide block 1032 extends to the outside of the guide groove 1031 and is fixedly connected to the adjusting block 1024. A second adjusting rod 1033 is rotatably arranged on the connecting block 1023. One end of the second adjusting rod 1033 extends to the inside of the guide groove 1031 and is threadedly connected to the guide block 1032. The other end of the second adjusting rod 1033 passes through the connecting block 1023 and extends to the outside of the fixed shaft 11. The second adjusting rod 1033 can slide against the fixed shaft 11.

[0035] like Figure 5As shown, a limiting groove 1041 is provided inside the connecting groove 15. The opening direction of the limiting groove 1041 is the same as that of the guide groove 1031. A limiting block 1042 is fixedly provided at one end of the adjusting block 1024 away from the connecting block 1023. The limiting block 1042 moves synchronously with the adjusting block 1024. The limiting block 1042 is slidably connected to the limiting groove 1041. The limiting block 1042 slides along the opening direction of the limiting groove 1041.

[0036] like Figures 7 to 9 As shown, a circular groove 1051 communicating with the connecting groove 15 is horizontally opened on the fixed shaft 11. A threaded rod 1053 is provided on one side of the fixed shaft 11. One end of the threaded rod 1053 extends into the interior of the circular groove 1051 and is fixedly provided with a disc 1054. The disc 1054 is slidably disposed with the inner wall of the circular groove 1051. A threaded hole 1052 is opened at one end of the main shaft 10 facing the fixed shaft 11. The end of the threaded rod 1053 away from the fixed shaft 11 can extend into the interior of the threaded hole 1052. The threaded rod 1053 is threadedly connected to the threaded hole 1052. The assembly plate 1025 has a slot 1061 at the end away from the first adjusting rod 1021. The disc 1054 has a horizontally formed inner groove 1062 that communicates with the connecting groove 15. A push plate 1063 is slidably arranged inside the inner groove 1062. A locking block 1064 is fixedly arranged at one end of the push plate 1063. The end of the locking block 1064 away from the push plate 1063 can extend to the outside of the disc 1054 and engage with the slot 1061. A telescopic rod 1065 is fixedly arranged between the end of the push plate 1063 away from the locking block 1064 and the inner wall of the inner groove 1062. A second spring is sleeved on the outside of the telescopic rod 1065. Spring 1066, the two ends of the second spring 1066 are fixedly connected to the inner wall of the inner groove 1062 and the push plate 1063 respectively. The second spring 1066 is in a compressed state when it is not under force. At this time, the locking block 1064 is separated from the locking groove 1061. The telescopic rod 1065 is divided into two sections. The two sections of the telescopic rod 1065 are fixedly connected to the inner wall of the inner groove 1062 and the push plate 1063 respectively. The telescopic end of the telescopic rod 1065 is fixedly set to the push plate 1063. When working, the telescopic rod 1065 moves synchronously with the push plate 1063 to provide stable support for the disc 1054 and the assembly disc 1025.

[0037] like Figure 7As shown, the fixed shaft 11 has an installation channel 1071 that communicates with the connecting groove 15. A baffle 1072 is provided inside the installation channel 1071. One end of the baffle 1072 can abut against the locking block 1064. The side of the locking block 1064 facing the installation channel 1071 is designed with an inclined surface. An assembly groove 1073 is provided at the end of the baffle 1072 away from the locking block 1064. An assembly plate 1025 is located on the inner wall of the assembly groove 1073 and can be rotatably connected to the assembly groove 1073. A lever 1074 is fixedly provided on the outer surface of the baffle 1072. One end of the lever 1074 extends to the outside of the fixed shaft 11.

[0038] like Figure 5 As shown, the threaded rod 1053 has an insertion hole 1081, and the spindle 10 has an insertion channel 1082 that communicates with the threaded hole 1052. An insertion rod 1083 is slidably disposed inside the insertion channel 1082. One end of the insertion rod 1083 can extend into the inside of the threaded hole 1052 and be inserted into the insertion hole 1081. The other end of the insertion rod 1083 extends to the outside of the spindle 10. When the threaded rod 1053 abuts against the threaded hole 1052, the insertion hole 1081 is aligned with the insertion channel 1082. By inserting the insertion rod 1083 into the insertion hole 1051 on the threaded rod 1053, the threaded rod 1053 can be limited, preventing the threaded rod 1053 from rotating accidentally during operation.

[0039] First, place the base 1 in a suitable position, and place the cable to be cabled on the cable cradle frame 4. The cable is installed through the cable cradle frame 4. Then, one end of the cable is passed through the first inlet hole 5 on the cable cradle frame 4 and the second inlet hole 7 on the second mounting plate 6. The cable is then passed between the tensioning shafts 14 and finally led out through the traction hole 9 on the traction plate 8. When the cable is not tensioned enough after passing through the traction hole 9, the connecting rod 16 is moved inside the connecting groove 15 by the pushing structure. The connecting rod 16 pushes the sliding plate 13 to slide inside the sliding groove 12. During the sliding process, the sliding plate 13 compresses the first spring 17. Simultaneously, the sliding plate 13 drives the tensioning shaft 14 to move, so that the tensioning shaft 14 drives the cable to be tensioned. This effectively adjusts the tension of the cable, ensuring that the cable maintains a suitable tension during the cabling process and improving the quality of the cabling.

[0040] The starter motor 1011 drives the first rotating shaft 1012 to rotate, which in turn drives the main shaft 10 to move. The main shaft 10 drives the first mounting plate 3 and the second mounting plate 6 to rotate. At the same time, the main shaft 10 drives the drive wheel 1013 to rotate. Under the action of the meshing structure, the drive wheel 1013 drives the driven wheel 1014 to rotate. Then, the driven wheel 1014 drives the second rotating shaft 1015 to rotate, which in turn drives the cable cradle 4 to move. During the operation of the first mounting plate 3, the cable cradle 4 is kept horizontal with the first mounting plate 3 to improve the twisting accuracy. Then, the second mounting plate 6 and the traction plate 8 move synchronously under the action of the cable. The cable is led out through the traction plate 8 and then twisted through the take-up mechanism.

[0041] The rotating block 1022 drives the first adjusting rod 1021 to rotate. Under the action of the threaded structure, the first adjusting rod 1021 drives the connecting block 1023 to slide inside the connecting groove 15, causing the connecting block 1023 to move towards the connecting rod 16. Simultaneously, the connecting block 1023 drives the adjusting block 1024 to move. When the adjusting block 1024 abuts against the connecting rod 16, it can push the connecting rod 16 to move. When the connecting block 1023 moves, the second adjusting rod 1033 will move synchronously. The connecting block 1023 moves. When a cable needs to be tensioned, the corresponding second adjusting rod 1033 can be rotated to move the adjusting block 1024. The adjusting block 1024 is made to abut against the connecting rod 16 to push the connecting rod 16 to move. Then, the connecting rod 16 pushes the sliding plate 13, which drives the tensioning shaft 14 to tension the corresponding cable. This flexibly adapts to the different tensioning states of different cables and better meets the requirements for individual tensioning of different cables during the cabling process.

[0042] When the adjusting block 1024 moves away from the connecting rod 16, the adjusting block 1024 is separated from the connecting rod 16. At this time, the first spring 17 resets and pushes the sliding plate 13 to slide in the sliding groove 12, so that the sliding plate 13 moves to the initial state.

[0043] Pulling the lever 1074 causes the baffle 1072 to move away from the fixed shaft 11 within the installation channel 1071, separating the baffle 1072 from the fixed shaft 11. This cancels the baffle 1072's abutment and limiting effect on the locking block 1064. At this time, the second spring 1066 resets, pushing the push plate 1063 to slide within the inner groove 1062. The push plate 1063 then moves the locking block 1064 towards the slot 1061. Simultaneously, the push plate 1063 moves the telescopic rod 1065, inserting the locking block 1064 into the slot 1061, thus completing the locking and limiting effect on the disc 1054. Then, pulling the insertion rod 1083 moves it away from the insertion hole 1081 within the insertion slot 1082. By moving the directional rod 1083 away from the insertion hole 1081, the limiting position on the threaded rod 1053 can be removed. At this time, rotating the fixed shaft 11, under the engaging action of the locking block 1064 and the locking groove 1061, the fixed shaft 11 synchronously drives the disc 1054 to rotate, causing the disc 1054 to drive the threaded rod 1053 to rotate. Under the action of the threaded structure, the threaded rod 1053 moves away from the main shaft 10, realizing the separation of the fixed shaft 11 from the main shaft 10, thereby realizing the disassembly of the traction disc 8. When dealing with cables of different diameters, the appropriate traction disc 8 can be replaced according to actual needs, thereby better meeting the cabling requirements of cables of different diameters and improving the adaptability of the equipment to diverse cable processing.

[0044] Under the action of the locking structure between the locking block 1064 and the locking slot 1061, rotating the fixed shaft 11 will synchronously drive the threaded rod 1053 to rotate. Under the action of the threaded structure, the threaded rod 1053 drives the fixed shaft 11 to move towards the main shaft 10 within the threaded hole 1052. When the fixed shaft 11 abuts against the main shaft 10, the threaded rod 1053 abuts against the inner wall of the threaded hole 1052, and at the same time, the insertion hole 1081 aligns with the insertion through slot 1082. Then, the insertion rod 1083 is moved from the insertion through slot 1082 towards the insertion hole 1081, so that the insertion rod 1083 is inserted into the interior of the insertion hole 1081, thereby completing the limiting of the threaded rod 1053 and preventing the threaded rod 1053 from rotating accidentally during operation. Then, the baffle 1072 is inserted into the installation channel 1071, so that... The baffle 1072 moves along the mounting channel 1071 toward the connecting groove 15. When the baffle 1072 abuts against the inclined surface of the locking block 1064, the locking block 1064 drives the push plate 1063 to slide in the inner groove 1062 under the action of abutment. During the sliding process, the push plate 1063 compresses the second spring 1066, causing the locking block 1064 to move away from the locking groove 1061. At this time, the baffle 1072 drives the assembly groove 1073 to abut against the assembly plate 1025. The interface completes the separation of the locking block 1064 from the locking groove 1061, thereby eliminating the limit between the disc 1054 and the assembly plate 1025. This prevents the first adjusting rod 1021 from synchronously driving the disc 1054 and the threaded rod 1053 to rotate through the assembly plate 1025 when it moves, thus improving the stability of the device.
