Description

Technical Field

[0001] The invention relates to the technical field of cable manufacturing, and in particular to a cable supporting device for cable manufacturing equipment. Background Art

[0002] In the cable production process, stranding is a key link. Stranding is to twist multiple single wires together according to certain rules to form the conductor core of the cable. This process is crucial to the performance of the cable, because the twisted core wire can not only improve the conductivity of the cable, but also enhance its flexibility and tensile strength. In the stranding process, it is necessary to accurately control the parameters such as the twisting pitch, single wire tension and twisting direction to ensure that the quality of the core wire meets the strict requirements of cable production. The stranding machine, as the core equipment, is responsible for driving the single wire to twist, and its performance directly affects the quality and production efficiency of the stranding. The take-up device collects the finished cables in an orderly manner after the stranding is completed. The take-up speed and tension control play a key role in the winding quality and storage convenience of the cable. The support device between the re-twisting machine and the take-up device also plays an important role. It needs to provide stable support during the cable transmission process to ensure that the cable maintains a suitable position and posture, and at the same time adapt to various dynamic changes in the cable production process.

[0003] However, during the stranding process, if the take-up device gets stuck, rotates inflexibly, or the motor fails, the tension on the cable will be instantly unbalanced. The instantaneous imbalance of tension makes the cable very easy to fall off the support roller. During the falling process, the cable may be scratched, stretched, twisted, etc., which will damage the physical structure of the cable and reduce its electrical performance, thereby greatly increasing the scrap rate and directly leading to a significant increase in production costs. At the same time, if the speed of the take-up device is too fast, the cable will be continuously tightened. For the stranding machine, the increasing reverse tension will cause tremendous pressure on its transmission system, twisting components, etc. The belts and chains in the transmission system may break due to overload, and the gears may be damaged by wear, tooth breakage, etc.

[0004] Based on the above viewpoints, the present invention provides a cable support device for cable production and manufacturing equipment. Summary of the invention

[0017] 3. After the cutting is completed, one end of the cable is still clamped in the movable roller at the stranding machine.

At the same time, this method allows the staff to have a longer buffer time to adjust related equipment.

[0018] 4. When cutting the cable, the side limit plate moves upward together. At this time, the clamping block will be stuck in the bottom of the fixed chuck so that the cable connected to the take-up device is clamped by the fixed chuck and the clamping block. At this time, the cable connected to the take-up device is connected to the limit steel rope through the fixed chuck, the clamping block, and when the cable comes off the movable roller, the limit steel rope will limit the cable within a safe range, effectively avoiding the rebound phenomenon caused by the internal residual stress or inertia at the moment of cutting. This rebound cable may cause harm to the operator or damage the surrounding equipment. The limit steel rope can effectively limit the rebound range of the cable and control the movement of the cable within a safe area, thereby ensuring the personal safety of the operator and the integrity of the equipment.

[0037] like Figure 2 , Figure 3 , Figure 4 , Fig.10 and Fig.11As shown, the bottom of the center connecting plate 22 is also fixedly connected to the bottom drive wedge block 24, and the outer wall of the spring mounting frame 113 is also fixedly connected to the main drive wedge block 115 that cooperates with the bottom drive wedge block 24 through a bracket.

The active bevel gear 52 is arranged inside the outer fixed shell 57. One end of the active bevel gear 52 is fixedly connected to the gear mounting frame 51, and the other end of the outer fixed shell 57 is internally connected to the limiting sleeve 56 through a spring limit sliding connection, and the inner part of the limiting sleeve 56 is connected to the movable frame 53 through a spring, and a plurality of fixed rods 54 are fixedly connected to the front side wall of the movable frame 53, and the plurality of fixed rods 54 penetrate the limiting sleeve 56, and the other end surface of the gear mounting frame 51 is provided with A plurality of driving convex teeth 510 are distributed in a circular array, and a movable gear 55 is fixedly connected to the outer wall of the movable frame 53.

[0038] like Fig.10 , Fig.11 and Fig.12As shown, the interior of the support rail 1 is connected to a driving plate 14 through a spring, and a spring plate 13 is fixedly connected to the inner wall of the driving plate 14, and the top of the spring plate 13 abuts against the outer wall of the limiting sleeve 56.

[0039] like Figure 5 and Figure 7As shown, this embodiment provides another technical solution based on the first and second embodiments. A clamping assembly 8 is installed at the top position of the front side walls of the two fixing frames 43. The clamping assembly 8 includes a sliding rod 81. The other ends of the two sliding rods 81 are connected to sleeves 82 through springs. A magnetic suction cup 83 is fixedly connected between the two sleeves 82. A fixed chuck 84 is attracted to the bottom of the magnetic suction cup 83. A cable guard 7 is fixedly connected to the middle position of the front side wall of the cable cutting assembly 2. The cable guard 7 includes a roller bracket 71. The inner part of the roller bracket 71 is rotatably connected to a steel rope roller 72. The outer part of the steel rope roller 72 is wound with a limiting steel rope 73. The upper side wall of the roller bracket 71 is fixedly connected to a lifting frame 74. A clamping block 75 is placed on the top of the lifting frame 74. The clamping block 75 cooperates with the fixed chuck 84. The top of the limiting steel rope 73 It is fixedly connected with the clamping block 75. When cutting the cable, the side limit plate 21 moves upward together. At this time, the clamping block 75 will be clamped into the bottom of the fixed clamping disk 84 so that the cable connected to the take-up device is clamped by the fixed clamping disk 84 and the clamping block 75. At this time, the cable connected to the take-up device is connected to the limiting steel rope 73 through the fixed clamping disk 84 and the clamping block 75. When the cable comes off the movable roller 41, the limiting steel rope 73 will limit the cable within a safe range, effectively avoiding the rebound phenomenon caused by the internal residual stress or inertia at the moment of being cut. This rebounding cable may cause harm to the operator or damage the surrounding equipment. The limiting steel rope 73 can effectively limit the rebound range of the cable and control the movement of the cable within a safe area, thereby ensuring the personal safety of the operator and the integrity of the equipment.

[0040] Working principle: After the stranding machine completes the stranding process, the stranded wire is led out from the outlet of the stranding machine, and the wire harness is supported by the auxiliary tension roller 3 and the movable rollers 41 on both sides and collected on the wire-taking device, and the auxiliary tension roller 3 is connected to the cable cutting assembly 2 through an air spring, so the auxiliary tension roller 3 can select different support angles by rotating, thereby providing a certain tension for the wire harness, and in the process of wire harness collection, the driving motor 101 drives the driving bevel gear 102 to rotate, and then drives the driven bevel gear 44 and the active bevel gear 52 to rotate together, and in the process of rotation of the driven bevel gear 44, the two movable rollers 41 and the limiting cylinder 42 in the middle of them rotate together, and the active rotation of the movable roller 41 can avoid the friction between the wire harness and the movable roller 41 to cause wear of the wire harness, and when the active bevel gear 52 rotates, it will drive the gear mounting frame 51 and the gear mounting frame 52 to rotate. Several driving convex teeth 510 on the outside of the frame 51 rotate together, and when the driving convex teeth 510 rotate at a high speed, they will continuously drive the fixed rod 54 and the movable frame 53 connected to the fixed rod 54 to extend and retract forward and backward. In the process of the fixed rod 54 extending and retracting forward and backward, the push rod 59 will also be driven to extend and retract forward and backward, thereby driving the driving lever 9 to rotate. In the process of the driving lever 9 rotating, the centering driving rod 12 at the bottom of the driving lever 9 drives the bottom driving block 45 to move, and then uses the active tooth plate 46 to drive the driving gear 48 to rotate. In the process of the driving gear 48 rotating, it will drive the driven tooth plate 47 to slide, thereby driving the two bottom driving blocks 45 to approach each other. When the two bottom driving blocks 45 approach each other, the two movable rollers 41 are driven to approach each other through the fixed frame 43, thereby aligning the wiring harness between the two movable rollers 41 to prevent the wiring harness from being completely separated from the supporting device due to the deviation of the wiring harness.

[0041] At the same time, a tension detection system is arranged on the outside of the support device, which can detect the tension of the wire harness in real time. The tension detection system can be selected as an electrical tension detection system that uses a magnetostrictive tension sensor for real-time detection. It mainly uses a sensitive element made of magnetostrictive material inside the sensor. When the tension of the wire acts on the sensor, it will cause the magnetic properties of the sensitive element to change. By detecting the change of the electromagnetic signal caused by the change of the magnetic property, the tension can be accurately measured. When the wire-winding device is stuck, rotated inflexibly, and other abnormalities occur, the tension on the cable will be much greater than the detection threshold of the magnetostrictive tension sensor. The sensor will then feed back the detection signal to the external controller, and the external controller will then control the brake cylinder 111 to pull the spring mounting bracket 113 inward. The magnetostrictive tension sensor can be selected as the MK4-S non-contact magnetostrictive linear displacement sensor.

[0042] When the brake cylinder 111 pulls the spring mounting frame 113 to move inward, the spring mounting frame 113 will drive the two bottom drive blocks 45 to move closer to each other, and then drive the two movable rollers 41 to move closer to each other, so that the cable in the middle position of the movable roller 41 is clamped. At the same time, due to the long inward movement of the movable roller 41, the driven bevel gear 44 is separated from the driving bevel gear 102, and the movable roller 41 no longer rotates, and the spring mounting frame 113 sliding inward will pull the drive plate 14 together. When the limiting sleeve 56 slides inward, it will drag the movable frame 53 inward together until the fixing rod 54 is completely inserted into the fixing groove 58. At this time, the movable frame 53 is connected with the gear mounting frame 51, and the movable gear 55 is directly above the tail gear plate 62. As the driving bevel gear 102 continues to rotate, the active bevel gear 52 will drive the fixing rod 54 to rotate together, and then drive the tension roller mounting frame 6 to slide forward.

[0043] When the tension roller mounting frame 6 moves forward, the main drive wedge block 115 squeezes the lower bottom surface of the bottom drive wedge block 24, thereby driving the center connecting plate 22 and the two side limit plates 21 to move upward, and the rising cutting blade 23 is used to cut the cable. While cutting the cable, the movable rollers 41 on both sides continue to squeeze inward, causing the cable to be squeezed and deformed. Therefore, when cutting, the cable is not easy to detach from the movable rollers 41 on both sides, and the cutting surface is also smoother, which is convenient for subsequent wiring work. After the cutting is completed, one end of the cable is still clamped in the movable roller 41 at the stranding machine, and the movable roller 41 moving forward will drag the cable line forward, ensuring that the cable line output by the stranding machine still maintains a high tension, avoiding the sudden disappearance of the tension at the rear end of the cable, and the change in the pitch of the stranded wire caused by the continuous operation of the stranding machine. At the same time, this method allows the staff to have a longer buffer time to adjust the relevant equipment.

[0044] When cutting the cable, the side limit plate 21 moves upward together. At this time, the block 75 will be stuck in the bottom of the fixed chuck 84 so that the cable connected to the take-up device is clamped by the fixed chuck 84 and the block 75. At this time, the cable connected to the take-up device is connected to the limit steel rope 73 through the fixed chuck 84 and the block 75. When the cable comes out of the movable roller 41, the limit steel rope 73 will limit the cable within a safe range, effectively avoiding the rebound phenomenon caused by the internal residual stress or inertia at the moment of being cut. This rebound cable may cause harm to the operator or damage the surrounding equipment. The limit steel rope 73 can effectively limit the rebound range of the cable and control the movement of the cable within a safe area, thereby ensuring the personal safety of the operator and the integrity of the equipment.
