Description

Technical Field

[0001] This invention belongs to the field of wire and cable conductor manufacturing technology, specifically a device for stranding conical and trapezoidal conductors. Background Technology

[0002] With the rapid development of high-voltage power transmission, new energy power generation, rail transit and other fields, the industry's demand for cable conductors with high current carrying capacity and high structural stability continues to increase. The circular trapezoidal stranded conductor is composed of a central circular conductor and an outer trapezoidal conductor. With its advantages such as high fill factor, small conductor outer diameter, large current carrying capacity and strong resistance to deformation, it is widely used in high-voltage power cables, special cables for new energy equipment and other scenarios. The guiding and limiting accuracy and operational stability of the conductor stranding equipment directly determine the forming quality, structural consistency and electrical performance of the circular trapezoidal stranded conductor.

[0003] A cage-type stranding machine is a core piece of equipment for conductor stranding. A search revealed Chinese Patent Publication No. CN206758188U, which discloses a novel cage-type stranding machine. This machine includes a frame, a wire feeding mechanism, a tension guide wheel, a wire feeding motor, a synchronous belt, and a precision guide rail. A motor is mounted on the left side of the frame and connected to a reduction mechanism. The rear of the wire feeding mechanism is connected to a wire distributor via a main shaft, and the wire distributor is mounted on the upper surface of the support base. The wire feeding motor is mounted on the lower surface of the cradle, and a servo driver is mounted at the rear of the motor. A servo motor is mounted on the upper end of the servo driver. The servo motor is connected to the tension guide wheel via a synchronous belt, and a precision guide rail is mounted inside the tension guide wheel. This novel cage-type stranding machine employs a servo closed-loop tension control system with a servo motor as the actuator, integrating mechanical, electrical, and computer technologies. It boasts advantages such as intelligent equipment, high-speed wire feeding, high-quality wire feeding, and automated control technology. It can stably control wire feeding and adjust the tension upon startup.

[0004] While the above-mentioned technical solutions can meet the stable batch stranding requirements of conventional circular cross-section conductors through a servo closed-loop tension control system, they lack dedicated circumferential attitude constraints and limiting capabilities for trapezoidal cross-section conductors used in circular-trapezoidal stranded conductors. They cannot restrict the degree of freedom of rotation of the conductor around its own axis. During the stranding and conveying process, the trapezoidal conductor is easily affected by factors such as equipment operation vibration, tension fluctuations, and residual internal stress, which can lead to defects such as loose wire bonding, loose structure, substandard filling coefficient, and excessive outer diameter fluctuation in the stranded conductor. It is difficult to guarantee the structural stability and electrical performance of the finished conductor. Summary of the Invention

[0007] In the above technical solution, preferably, the clamping and pressing component includes a vertical frame disposed on the right side of the dual-axis electric cylinder. The bottom of the vertical frame is fixedly installed on the top of the base. An adjustment plate is disposed on the inner side of the vertical frame. The left side of the adjustment plate is fixedly installed on the output end of the right side of the dual-axis electric cylinder. A pressing shaft is slidably connected to the top and bottom of the adjustment plate. The front and rear sides of the pressing shaft are slidably connected to the inside of the vertical frame.

[0008] In the above technical solution, preferably, the guide includes a guide rod, the guide rod is slidably connected inside the moving block, the surface of the guide rod is fixedly installed on the surface of the reference block, and a second spring is sleeved on the surface of the guide rod, the surface of the second spring being in contact with the surfaces of the reference block and the moving block.

[0009] In the above technical solution, preferably, protective plates are fixedly installed on the left side of both the top and bottom of the guide sleeve, and the guide rod is located inside the protective plate.

[0010] In the above technical solution, preferably, a limiting plate is fixedly installed on the surface of the protective plate, the surface of the limiting plate is fixedly installed on the surface of the guide sleeve, and the right side of the limiting plate is in contact with the left side of the push frame.

[0011] In the above technical solution, preferably, the top and bottom of the positioning sleeve are fixedly connected with reinforcing rods, and the surface of the reinforcing rods is fixedly installed inside the push frame.

[0012] In the above technical solution, preferably, two inclined blocks are fixedly installed on the surface of the U-shaped movable frame.

[0013] In the above technical solution, preferably, a stabilizing block is fixedly installed on the surface of the deburring blade, and the surface of the stabilizing block is fixedly installed inside the fixing ring and the adjusting ring, and the number of stabilizing blocks is the same as the number of deburring blades.

[0014] In the above technical solution, preferably, a positioning guide rail is fixedly installed on the surface of the adjustment plate, the positioning guide rail is slidably connected inside the vertical frame, and reinforcing frames are fixedly installed on both sides of the vertical frame, with the bottom of the reinforcing frame fixedly installed on the top of the base.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention achieves axial pre-positioning by simultaneously inserting the central circular wire to be twisted and the outer trapezoidal wire output from the winch into the guide sleeve. Then, a dual-axis electric cylinder synchronously drives the left output end to move the push frame axially along the guide sleeve. The push frame, in conjunction with the U-shaped moving frame, moves the clamping ring synchronously into the guide sleeve, applying radial clamping force to multiple outer trapezoidal wires simultaneously. At the same time, the pressure sensor on the connecting plate collects the clamping force data in real time and feeds it back to the control system. This effectively solves the problem that traditional equipment cannot accurately limit the positioning of trapezoidal wires by clamping and constraining the radial movement and circumferential deflection of the trapezoidal wires.

[0016] Furthermore, when the dual-axis electric cylinder drives the push frame to move to the right to press the wire, the L-shaped pull rod inside the push frame moves to the right simultaneously, pushing the adjusting ring to rotate circumferentially through the arc-shaped inclined plate. This causes the deburring blades inside the fixed ring and adjusting ring to close, removing burrs from the passing trapezoidal wire. At the same time, the ring blade structure provides secondary auxiliary positioning for the trapezoidal wire, constraining its movement and deflection. When the push frame resets, the spring and the spring plate drive all components to automatically return to their original positions, which not only avoids finished product defects caused by burrs but also enhances the limiting accuracy of the trapezoidal wire.

[0017] Furthermore, when the dual-axis electric cylinder starts operation, the right output shaft synchronously drives the clamping mechanism, and the right output shaft synchronously pushes the adjusting plate to move to the left. Under the guidance of the positioning guide rail, the adjusting plate feeds along the vertical frame. The inclined slide groove inside drives the top and bottom pressing shafts to move towards the center synchronously along the vertical slide groove of the vertical frame, and synchronously clamps the rear end of the conductor that has just been stranded. After the operation is completed, the dual-axis electric cylinder resets, and the adjusting plate moves to the left to drive the pressing shaft to release synchronously, which greatly improves the stability of stranding and the finished product qualification rate.

An arc-shaped inclined plate 1110 is fixedly installed on the front and rear sides of the left side of the adjusting ring 112. The surface of the L-shaped pull rod 118 is in contact with the inclined surface of the arc-shaped inclined plate 1110.

[0024] Specifically, the deburring blade 113 uses commercially available Kyocera standard high-speed steel deburring blades, with sharp and wear-resistant cutting edges, which can stably remove burrs from the surface of copper wires without scratching the wire substrate, and is suitable for processing wires of different specifications; the arc-shaped inclined plate 1110, with its guide inclined surface, can smoothly realize the conversion of axial to circumferential force; the L-shaped pull rod 118, through contact with the guide inclined surface of the arc-shaped inclined plate 1110, can push the adjusting ring 112 to rotate through the arc-shaped inclined plate 1110; the spring piece 116 can drive the adjusting ring 112 to quickly reset, and at the same time buffer the rotational impact force of the adjusting ring 112 to avoid impact damage to the components; the spring 119 can accurately provide the reset force of the L-shaped pull rod 118, ensuring the accuracy and stability of the reset action; the reference block 114 and the moving block 115 provide a stable installation reference for the spring piece 116; the positioning sleeve 117 can accurately guide the sliding of the L-shaped pull rod 118, avoiding the deviation of the L-shaped pull rod 118 during the sliding process.

[0025] like Figures 1 to 2 As shown, the clamping and pressing component 12 includes a vertical frame 121 disposed on the right side of the dual-axis electric cylinder 5. The bottom of the vertical frame 121 is fixedly installed on the top of the base 1. An adjusting plate 122 is disposed on the inner side of the vertical frame 121. The left side of the adjusting plate 122 is fixedly installed on the output end of the right side of the dual-axis electric cylinder 5. A pressing shaft 123 is slidably connected to the top and bottom of the adjusting plate 122. The front and rear sides of the pressing shaft 123 are slidably connected to the inside of the vertical frame 121.

[0026] Specifically, the vertical frame 121 provides a stable installation reference for the entire clamping and pressing component 12, ensuring the stability of the clamping action; the inclined groove inside the adjusting plate 122 is precision ground, which can accurately drive the pressing shaft 123 to move synchronously; the surface of the pressing shaft 123 is covered with a 1 mm thick polyurethane elastic layer, which not only has sufficient clamping friction to prevent conductor movement, but also avoids scratching the surface of the copper conductor, and can also adapt to the clamping requirements of conductors of different specifications; the positioning guide rail 20 adopts a high-precision linear guide rail to ensure the smoothness of the movement and positioning accuracy of the adjusting plate 122, and avoid skewing during the clamping process.

[0027] like Figures 5 to 8 As shown, a guide is mounted on the surface of the reference block 114. The guide includes a guide rod 13. The guide rod 13 is slidably connected inside the movable block 115. The surface of the guide rod 13 is fixedly mounted on the surface of the reference block 114. A second spring 14 is sleeved on the surface of the guide rod 13. The surface of the second spring 14 is in contact with the surfaces of the reference block 114 and the movable block 115.

[0028] Specifically, the guide rod 13 serves as the sliding guide reference for the moving block 115, ensuring the long-term sliding accuracy of the moving block 115 and preventing wear gaps. The guide hole inside the moving block 115 is precision ground, and its cooperation with the guide rod 13 ensures smooth sliding. The second spring 14 has stable elastic deformation capability and ultra-long fatigue life, and can accurately provide reset force and buffer force, ensuring the reset accuracy of the adjusting ring 112. The reference block 114 provides a stable fixed reference for the guide rod 13, ensuring the coaxiality of the guide rod 13 during installation.

[0029] like Figures 3 to 4 As shown, protective plates 15 are fixedly installed on the top and bottom left sides of the guide sleeve 4. The guide rod 13 is located inside the protective plate 15. A limiting plate 16 is fixedly installed on the surface of the protective plate 15. The surface of the limiting plate 16 is fixedly installed on the surface of the guide sleeve 4. The right side of the limiting plate 16 is in contact with the left side of the push frame 6.

[0030] Specifically, the protective plate 15 can protect the internal guide rod 13 and spring 14 and other precision moving parts in the complex environment of the workshop for a long time, avoiding jamming and wear caused by foreign object intrusion; the limiting plate 16 can stably withstand the extreme impact force of the push frame 6. The end face of the plate that contacts the push frame 6 is pasted with a 5 mm thick polyurethane buffer pad, which can absorb the impact force and avoid vibration and component damage caused by hard collision. At the same time, the limiting plate 16 and the guide sleeve 4 are fixed with precision bolts, which has high installation accuracy and can accurately control the left limit stroke of the push frame 6, ensuring the consistency of the clamping amplitude in each operation.

[0031] like Figures 3 to 9 As shown, the top and bottom of the positioning sleeve 117 are fixedly connected with reinforcing rods 17. The surface of the reinforcing rods 17 is fixedly installed inside the push frame 6. The surface of the U-shaped moving frame 7 is fixedly installed with inclined blocks 18. There are two inclined blocks 18. The surface of the deburring blade 113 is fixedly installed with stabilizing blocks 19. The surface of the stabilizing blocks 19 is fixedly installed inside the fixing ring 111 and the adjusting ring 112. The number of stabilizing blocks 19 is the same as the number of deburring blades 113.

[0032] Specifically, the reinforcing rod 17, positioning sleeve 117, and push frame 6 are all fixed by welding to prevent loosening under long-term stress; the guide slope of the inclined block 18 is precision ground to ensure the smooth sliding of the U-shaped moving frame 7, while dispersing the pressing reaction force to prevent deformation of the U-shaped moving frame 7; the stabilizing block 19 is integrally machined with the ring body, and each stabilizing block 19 corresponds to a deburring blade 113, which can accurately position and reinforce the deburring blade 113 to prevent shaking during operation, and at the same time, it will not add extra weight to the ring body, ensuring the flexibility of the adjustment ring 112 rotation.

[0033] like Figures 1 to 2 As shown, a positioning guide rail 20 is fixedly installed on the surface of the adjustment plate 122. The positioning guide rail 20 is slidably connected inside the vertical frame 121. A reinforcing frame 21 is fixedly installed on both sides of the vertical frame 121. The bottom of the reinforcing frame 21 is fixedly installed on the top of the base 1.

[0034] Specifically, the positioning guide rail 20 adopts a high-precision linear guide rail, which can ensure the smoothness of the movement of the adjustment plate 122 and the positioning accuracy, and avoid the deviation during the clamping process; the reinforcing frame 21 is welded and is fixed to the vertical frame 121 and the base 1 with high-strength bolts, which can evenly transmit the reaction force of the clamping operation to the base 1, greatly improving the installation stability of the vertical frame 121 and avoiding the tilting and loosening of the vertical frame 121 caused by long-term clamping operation.

[0035] The working principle and usage process of this invention are as follows: During use, the central circular wire and the outer trapezoidal wire to be twisted are passed sequentially through the fixing ring 111 and the adjusting ring 112, and then through the guide sleeve 4 to complete axial pre-positioning. After starting the equipment, the dual-axis electric cylinder 5 synchronously drives the left output shaft to drive the right transmission to push the pusher frame 6, and the right output shaft synchronously pushes the adjusting plate 122 to the left. During the left-side operation, the pusher frame 6, in conjunction with four sets of U-shaped moving frames 7, drives the clamping ring 10 to synchronously apply radial clamping force to multiple outer trapezoidal wires. The pressure sensor 9 collects the clamping force data in real time to achieve closed-loop adjustment, constraining the radial movement and circumferential deflection of the trapezoidal wires. Simultaneously, the L-shaped pull rod 118 inside the pusher frame 6 moves synchronously to the right. The L-shaped pull rod 118 pushes the adjusting ring 112 to rotate circumferentially through the guide slope of the arc-shaped inclined plate 1110. When the adjusting ring 112 rotates, the deburring blade inside it... The deburring blade 113 inside the fixed ring 111 closes with the plate 113, so that the two sides of the trapezoidal conductor come into contact with the deburring blade 113, removing burrs from the trapezoidal conductor and forming a secondary auxiliary positioning. The moving block 115 on the adjusting ring 112 slides along the guide rod 13 to compress the second spring 14. The guide rod 13 ensures the coaxiality of the rotation of the adjusting ring 112. During the right-side operation, the adjusting plate 122 is fed along the vertical frame 121 under the guidance of the positioning guide rail 20, driving the upper and lower pressing shafts 123 to move towards the center synchronously, clamping the rear end of the stranded conductor synchronously. The winch 2 starts and works with the above components to complete the stranding of the trapezoidal mixed conductor. After the operation is completed, the dual-axis electric cylinder 5 resets, and all moving parts automatically return to their positions under the elastic force of the first spring 119, the second spring 14, and the spring plate 116, which greatly improves the forming accuracy and production efficiency of the mixed conductor.

[0036] like Figure 10 As shown, this equipment is equipped with a closed-loop control system based on a programmable logic controller (PLC) for precise adjustment of the clamping force of the dual-axis electric cylinder 5. The system uses a pressure sensor 9 as a feedback element and the dual-axis electric cylinder 5 as an actuator to achieve closed-loop control of the radial clamping force of the trapezoidal conductor, ensuring that the clamping force is always maintained within the preset target range, thereby effectively constraining the radial movement and circumferential deflection of the conductor.

[0037] The control process is as follows: 1. Parameter preset: The operator presets the target clamping force value in the human-machine interface (HMI) according to the specifications, material and process requirements of the wire to be stranded. and allowable deviation range .

[0038] 2. Signal Acquisition: During equipment operation, pressure sensor 9 detects the force between push frame 6 and connecting plate 8 in real time. This force is equivalent to the radial clamping force of clamping ring 10 on trapezoidal wire. The sensor converts the force signal into an analog electrical signal (such as 4–20 mA or 0–10 V) and transmits it to the analog input module of PLC.

[0039] 3. Comparison and Calculation: The PLC will collect the actual clamping force. With target value Comparison: like If the clamping force is insufficient, there is a risk of wire movement. like The system then determines that the clamping force is too large, which may damage the wires or cause the drive mechanism to overload. like exist[ , If the value is within the specified range, the current control value remains unchanged.

[0040] 4. Control Output: The PLC controls the output based on the deviation value. Proportional-integral-derivative (PID) calculations are performed to generate corresponding control signals, which are then sent to the servo driver of the dual-axis electric cylinder 5 via an analog output module or bus communication (such as EtherCAT) to adjust the feed displacement and thrust at the left output end of the electric cylinder in real time.

[0041] 5. Dynamic adjustment: During the stranding process, if the clamping force deviates from the set range due to disturbances such as conductor cross-section fluctuations, changes in wire tension, and mechanical vibration, the system can automatically adjust the output of the electric cylinder within milliseconds to achieve real-time correction of the clamping force, ensuring that the clamping ring 10 pairs of multiple trapezoidal conductors always maintain stable and uniform radial constraint.

[0042] 6. Dual-end independent control: The left and right outputs of the dual-axis electric cylinder 5 are independently controlled by the PLC. The left output terminal controls the clamping force between the auxiliary positioning deburring part 11 and the clamping ring 10 according to the above closed-loop logic; The output terminal on the right side drives the clamping and pressing component 12 to complete the pressing and releasing of the conductor according to the stroke control logic. The two work together without interfering with each other.
