Description

Technical Field

[0001] This invention relates to the field of power fittings processing technology, and in particular to a digital forming equipment for vehicle-mounted wedge clamps. Background Technology

[0002] Wedge clamps are electrical fittings used in power transmission lines. Through the self-locking principle of the wedge structure, they firmly fix steel or aluminum stranded wires between poles, insulators, or fittings, realizing the mechanical connection and tension transmission of conductors / ground wires. Their wedge design can automatically adapt to changes in wire diameter, ensuring stable locking force. They are characterized by convenient installation, maintenance-free operation, and high reliability, and are widely used in conductor fixing, ground wire anchoring, and fitting connection scenarios in overhead power transmission lines. The production of traditional wedge clamps mainly relies on manual operation, which has the following technical drawbacks: Low feed accuracy: Manual feeding can easily lead to errors in the length of the steel strand (more than ±5mm), affecting installation compatibility; Safety hazards: Mechanical injuries can easily occur during manual shearing and shaping processes; Quality fluctuations: The tightness of the wedge clamps depends on workers tapping them, and there is a lack of real-time monitoring methods, resulting in a finished product qualification rate of less than 85%. Traceability difficulties: Production parameters are not digitally recorded, making it impossible to trace the source of faults, which is detrimental to quality improvement; Therefore, this invention proposes a vehicle-mounted wedge-shaped wire clamp digital forming device to solve the problems existing in the prior art. Summary of the Invention

[0003] To address the aforementioned issues, this invention proposes a vehicle-mounted wedge wire clamp digital forming device. This device improves the precision of steel strand processing through a closed-loop control system, reducing the cutting length error from the traditional ±5mm to ≤±0.1mm and the angle control precision to ±0.1°. The servo motor-driven multi-roller wire feeding mechanism, combined with a laser rangefinder, dynamically compensates for steel strand vibration, ensuring tension control precision.

[0004] To achieve the objectives of this invention, the invention is implemented through the following technical solution: a vehicle-mounted wedge-shaped wire clamp digital forming equipment, comprising a vehicle-mounted mobile platform, an automatic wire feeding module, an intelligent cutting unit, an angle monitoring system, a hydraulic forming system, and a central controller. The vehicle-mounted mobile platform is used to stabilize the equipment and provide a working platform under complex terrain conditions; the automatic wire feeding module is used to realize closed-loop control of steel strand tension; and the intelligent cutting unit is used for fixed-length cutting of steel strands and end-face quality inspection. The angle monitoring system is used to monitor the forming angle of the wedge clamp in real time and record surface defects; the hydraulic forming system is used for the hydraulic forming and pressure data acquisition of the wedge clamp; the central controller is used to coordinate the operation of each module, store production data, and realize human-machine interaction through the HMI interface.

[0005] A further improvement is that the vehicle-mounted mobile platform includes a heavy-duty truck chassis and hydraulic outriggers, the hydraulic outriggers being equipped with slope sensors to ensure that the equipment maintains a level operation on terrain with a slope of ≤15°.

[0006] Further improvements are made in that the automatic wire feeding module includes a servo motor-driven multi-roller wire feeding mechanism and a laser rangefinder. The tension control accuracy of the multi-roller wire feeding mechanism is ±0.3N, and the resolution of the laser rangefinder is 0.1mm, realizing closed-loop control of the steel strand feeding. Specifically, the following tension closed-loop control algorithm is adopted: Among them, F t For tension control output, L d For the target feed line length, L m For real-time length measurement, K p K i K d These are the proportional, integral, and derivative coefficients, respectively, to ensure tension control accuracy reaches ±0.3N and achieve dynamic error compensation for steel strand feeding.

[0007] Further improvements include: the intelligent cutting unit comprises a hydraulic shearing blade and an AI visual positioning module. The hydraulic shearing blade has a repeatability accuracy of ±0.05mm and a cutting length range of 300-1500mm. Multiple sets of parameters are preset through the HMI interface, and the following adaptive cutting control algorithm is adopted: Where Pc is the real-time cutting pressure, P0 is the base pressure value, K is the pressure fluctuation coefficient, and λ is the attenuation coefficient. Let w be the cutting speed, w be the vibration frequency, and t be the time. The phase angle ensures that the cutting length error is ≤ ±0.1mm and the repeatability accuracy reaches ±0.05mm.

[0008] A further improvement is made in that the AI ​​visual positioning module uses an AI visual positioning algorithm to identify the end face of the steel strand. Where S is the end face flatness score, and I i denoted as pixel grayscale value, μ as average grayscale value of the region, and N as the number of sampling points.

[0009] A further improvement is made in that: the angle monitoring system includes a multi-axis gyroscope and an industrial camera. The multi-axis gyroscope has a range of 0-90° and an accuracy of ±0.1°. The industrial camera has a built-in surface defect detection algorithm for real-time identification of surface defects in the wire clamp. The surface defect detection algorithm is as follows: D=max(∣∇I∣)−σ Where D is the degree of defect, ∇I is the image gradient, and σ is the noise threshold.

[0010] A further improvement lies in the fact that the angle monitoring system employs a multi-sensor fusion angle monitoring algorithm. Where θ is the fused angle value, θ g For measuring angles using a multi-axis gyroscope, θ v For measuring angles, θ, in industrial cameras c To calculate the angle for the pressure data distribution, w g w v w c These are the weighting coefficients for the corresponding sensors, achieving an angle measurement accuracy of ±0.1° within the 0-90° range.

[0011] A further improvement is made in the following: The hydraulic forming system includes a main pressure cylinder, a mold assembly, and a pressure sensor. The mold assembly includes an upper mold and a lower mold. The main pressure cylinder drives the upper mold to cooperate with the lower mold to hydraulically form the wedge-shaped wire clamp. The pressure range of the main pressure cylinder is 0-50 MPa. The pressure sensor is used to record the pressure curve in real time. When the pressure is over-pressurized, the pressure relief protection is automatically triggered. Specifically, the pressure relief protection is triggered by the following formula: Among them, P threshold P is the pressure relief threshold. max The rated maximum pressure is δ, which is the safety factor (default 0.1).

[0012] Further improvements include: the central controller stores production data, including cutting length, forming angle, pressure curve, and defect records, and supports data export and remote transmission.

[0013] A further improvement is that the central controller uses a data association analysis algorithm to manage production data. Among them, R xy Let x be the correlation coefficient of the parameters. i y i For sample values ​​of different production parameters, n represents the number of samples. The corresponding parameter averages are used to analyze the correlation between cutting length, forming angle, and pressure curve parameters, supporting quality traceability and process optimization.

[0014] The beneficial effects of this invention are as follows: 1. This invention improves the precision of steel strand processing through a closed-loop control system, reducing the cutting length error from the traditional ±5mm to ≤±0.1mm, and the angle control precision to ±0.1°. The servo motor-driven multi-roller wire feeding mechanism, combined with a laser rangefinder, dynamically compensates for steel strand vibration, ensuring tension control precision. The AI ​​vision positioning module works in conjunction with the hydraulic shearing blade to reduce the workload of manual re-inspection. In summary, this invention improves the mechanical performance of the forming clamp.

[0015] 2. This invention completely eliminates the risks of manual operation through automated design: the hydraulic shearing blade has a repeatability accuracy of ±0.05mm, avoiding finger entanglement accidents; the pressure sensor monitors the main pressure cylinder in real time, and automatically triggers pressure relief protection when overpressure occurs, eliminating the hidden danger of mold bursting; equipped with hydraulic outriggers and slope sensors, it can be quickly leveled on a 15° slope, improving deployment efficiency and making it suitable for emergency repair operations.

[0019] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0020] Example 1 according to Figure 1 As shown, this embodiment proposes a vehicle-mounted wedge clamp digital forming equipment, including a vehicle-mounted mobile platform, an automatic wire feeding module, an intelligent cutting unit, an angle monitoring system, a hydraulic forming system, and a central controller 10. The vehicle-mounted mobile platform is used to stabilize the equipment and provide a working platform under complex terrain conditions; the automatic wire feeding module is used to realize closed-loop control of steel strand tension; and the intelligent cutting unit is used for fixed-length cutting of steel strands and end-face quality inspection. The angle monitoring system is used to monitor the forming angle of the wedge clamp in real time and record surface defects; the hydraulic forming system is used for the hydraulic forming and pressure data acquisition of the wedge clamp; the central controller 10 is used to coordinate the operation of each module, store production data, and realize human-machine interaction through the HMI interface. The closed-loop control system improves the precision of steel strand processing, reducing the cutting length error from the traditional ±5mm to ≤±0.1mm, and the angle control precision to ±0.1°. The servo motor-driven multi-roller wire feeding mechanism 9, combined with the laser rangefinder 3, dynamically compensates for steel strand vibration, ensuring tension control precision. The AI ​​vision positioning module works in conjunction with the hydraulic shearing blade 12 to reduce manual re-inspection workload. In summary, this improves the mechanical performance of the formed clamp.

[0021] The vehicle-mounted mobile platform includes a heavy-duty truck chassis 1 and hydraulic outriggers 4. The hydraulic outriggers 4 are equipped with slope sensors to ensure that the equipment maintains a level operation on terrain with a slope of ≤15°.

[0022] The automatic wire feeding module includes a servo motor-driven multi-roller wire feeding mechanism 9 and a laser rangefinder 3. The tension control accuracy of the multi-roller wire feeding mechanism 9 is ±0.3N, and the resolution of the laser rangefinder 3 is 0.1mm, realizing closed-loop control of the steel strand feeding. Specifically, the following tension closed-loop control algorithm is adopted: Among them, F t For tension control output, L d For the target feed line length, L m For real-time length measurement, K p K i K d These are the proportional, integral, and derivative coefficients, respectively, to ensure tension control accuracy reaches ±0.3N and achieve dynamic error compensation for steel strand feeding.

[0023] The intelligent cutting unit includes a hydraulic shearing blade 12 and an AI vision positioning module. The hydraulic shearing blade 12 has a repeatability of ±0.05mm and a cutting length range of 300-1500mm. Multiple sets of parameters are preset through the HMI interface, and the following adaptive cutting control algorithm is adopted: Where Pc is the real-time cutting pressure, P0 is the base pressure value, K is the pressure fluctuation coefficient, and λ is the attenuation coefficient. Let w be the cutting speed, w be the vibration frequency, and t be the time. The phase angle ensures that the cutting length error is ≤ ±0.1mm and the repeatability accuracy reaches ±0.05mm.

[0024] The AI ​​visual positioning module uses an AI visual positioning algorithm to identify the end face of the steel strand: Where S is the end face flatness score, and I i denoted as pixel grayscale value, μ as average grayscale value of the region, and N as the number of sampling points.

[0025] The angle monitoring system includes a multi-axis gyroscope 7 and an industrial camera 2. The multi-axis gyroscope 7 has a range of 0-90° and an accuracy of ±0.1°. The industrial camera 2 has a built-in surface defect detection algorithm for real-time identification of surface defects in the wire clamp. The surface defect detection algorithm is as follows: D=max(∣∇I∣)−σ Where D is the degree of defect, ∇I is the image gradient, and σ is the noise threshold.

[0026] The angle monitoring system employs a multi-sensor fusion angle monitoring algorithm. Where θ is the fused angle value, θ g For measuring angles, θ using a multi-axis gyroscope 7 v To measure the angle θ of industrial camera 2 c To calculate the angle for the pressure data distribution, w g w v w c These are the weighting coefficients for the corresponding sensors, achieving an angle measurement accuracy of ±0.1° within the 0-90° range.

[0027] An array of pressure sensors 11 is deployed in key contact areas of the mold assembly (such as the wedge-shaped surface contact area) to collect pressure values ​​Pij (where i is the mold partition number and j is the time series) at different locations during the wire clamp forming process in real time, forming a two-dimensional pressure distribution matrix [P]. Based on the geometric characteristics of the wedge-shaped wire clamp, a mathematical mapping relationship between the pressure distribution and the actual forming angle is established: Where: k is the calibration coefficient (determined by mold design parameters); S represents the average pressure distribution. i,j The weighted area of ​​the corresponding pressure point (proportional to the unit area of ​​the mold contact area).

[0028] Based on the elasto-plastic properties of the clamp material, the mapping model parameters are corrected in real time by the central controller 10. When an asymmetric deviation occurs in the pressure distribution (such as an abnormal increase in pressure on one side), the angle calculation value is automatically compensated to ensure θ. c It can reflect the angular deviation caused by uneven material deformation.

[0029] This angle value serves as a supplementary parameter to the multi-sensor fusion algorithm, effectively compensating for the measurement drift of the multi-axis gyroscope 7 in high-frequency vibration scenarios, as well as the visual blind spots caused by oil stains / obstructions in the industrial camera 2, ultimately improving the reliability of the fusion angle θ.

[0030] The hydraulic forming system includes a main pressure cylinder 8, a mold assembly, and a pressure sensor 11. The mold assembly includes an upper mold 5 and a lower mold 6. The main pressure cylinder 8 drives the upper mold 5 to cooperate with the lower mold 6 to perform hydraulic forming of the wedge-shaped wire clamp. The pressure range of the main pressure cylinder 8 is 0-50 MPa. The pressure sensor 11 is used to record the pressure curve in real time. When the pressure is over-pressurized, the pressure relief protection is automatically triggered. Specifically, the pressure relief protection is triggered by the following formula: Among them, P threshold P is the pressure relief threshold. max The rated maximum pressure is δ, which is the safety factor (default 0.1).

[0031] The central controller 10 stores production data, including cutting length, forming angle, pressure curve and defect records, and supports data export and remote transmission.

[0032] The central controller 10 uses a data association analysis algorithm to manage production data. Among them, R xy Let x be the correlation coefficient of the parameters. i y i For sample values ​​of different production parameters, n represents the number of samples. The mean values ​​of the corresponding parameters are used to analyze the correlation between cutting length, forming angle, and pressure curve parameters, supporting quality traceability and process optimization. Each sample point i corresponds to one complete production process (such as the forming cycle of a wedge clamp). Each sample contains multiple parameter values. When the equipment continuously produces n clamps, the system records the complete parameter set for each clamp. The larger n is, the more reliable the correlation analysis results. The R-values ​​between different parameters are calculated. xy This allows for the discovery of potential patterns. The central controller 10 employs a sliding window mechanism, updating the latest n samples in real time. When the production process is adjusted, the system automatically recalculates R. xy This ensures that the analysis results reflect the current process status. The parameter design makes the algorithm adaptive, allowing it to dynamically adjust the analysis accuracy according to the actual production scale, while also supporting data association needs for small-batch customized production.

[0033] Example 2 according to Figure 1 As shown, this embodiment proposes a vehicle-mounted wedge-shaped wire clamp digital forming device, which is applied to field construction scenarios: Equipment deployment: Drive the truck to the work site, deploy the hydraulic outriggers and leveling equipment, and use the slope sensor to ensure that the horizontal error is ≤1°. Parameter settings: Input the cutting length (e.g., -00mm) and target wedge angle (e.g., 45°) via HMI. Automated processing The steel strand is fed by the multi-roller feeding mechanism 9, and the length is calibrated in real time by the laser rangefinder 3. The hydraulic shearing blade 12 completes the fixed-length cutting, and AI vision verifies the flatness of the end face. The steel strand is placed into the upper mold 5 and the lower mold 6, and the hydraulic system pressurizes it to 25MPa for forming. The multi-axis gyroscope 7 feeds back the angle data to the central controller 10. Data Records The system automatically generates reports containing timestamps, pressure curves, and angle deviations, and stores them locally or in the cloud.

[0034] Example 3 according to Figure 1 As shown, this embodiment proposes a vehicle-mounted wedge-shaped wire clamp digital forming equipment, which is applied to quality control scenarios: The molding video captured by industrial camera 2 is analyzed by AI, and the batch is automatically marked when the indentation depth exceeds the limit; Historical data can be used to compare the correlation between process parameters and fatigue strength, and optimize mold design.

[0035] Validation data: Table 1 This vehicle-mounted wedge-shaped wire clamp digital forming equipment improves the precision of steel strand processing through a closed-loop control system. The cutting length error is reduced from the traditional ±5mm to ≤±0.1mm, and the angle control accuracy reaches ±0.1°. A servo motor-driven multi-roller wire feeding mechanism 9, combined with a laser rangefinder 3, dynamically compensates for steel strand vibration, ensuring tension control accuracy. An AI vision positioning module works in conjunction with a hydraulic shearing blade 12 to reduce manual inspection workload. In summary, this improves the mechanical performance of the formed wire clamp. Furthermore, this invention completely eliminates the risks of manual operation through automated design: the hydraulic shearing blade 12 has a repeatability accuracy of ±0.05mm, preventing finger entanglement accidents; a pressure sensor 11 monitors the main pressure cylinder 8 in real time, automatically triggering pressure relief protection in case of overpressure, eliminating the risk of mold bursting; equipped with hydraulic support legs 4 and a slope sensor, it can quickly level on a 15° slope, improving deployment efficiency and making it suitable for emergency repair operations. Simultaneously, the central controller 10 integrates data management functions, recording parameters such as pressure curves, angle deviations, and defect images in real time.
