Description

Technical Field

[0001] This invention belongs to the field of vulcanization temperature monitoring technology for giant engineering radial tires. Specifically, it relates to a three-dimensional precise positioning and temperature measurement wiring method for continuously wound tire treads. It is applicable to the whole-process vulcanization temperature monitoring of giant tire treads in various continuous winding processes. It can be applied to the production quality control of giant tires used in mines, ports, and engineering machinery, providing measured data support for the optimization of vulcanization process parameters and the prediction of vulcanization defects, thereby improving the stability of giant tire production quality and service reliability. Background Technology

[0002] Giant radial engineering tires are core load-bearing components for heavy equipment operating under extreme conditions. Their treads typically employ a multi-layer continuous winding process, where layers of rubber are stacked to form a pre-defined rubber layer structure. The tread thickness and structural strength directly determine the load-bearing capacity and service performance of the giant tire. The vulcanization process is the core process in giant tire production. The uniformity, stability, and temperature control precision of the temperature field during vulcanization directly determine the degree of cross-linking, mechanical properties, wear resistance, and aging resistance of the tire body, thus affecting the safety and service life of the giant tire.

[0003] Vulcanization temperature measurement is a core technical means for vulcanization quality control. It can accurately capture the real-time temperature changes of the rubber compound in each winding layer, providing data support for optimizing vulcanization process parameters and avoiding under-vulcanization / over-vulcanization defects. It is a key link to ensure the consistency of production quality of giant tires.

[0004] The existing method for wrapping the tread with wires for temperature measurement in giant tires has the following technical defects: Poor reliability of lead wires: Traditional temperature measuring leads are exposed or interwoven across layers. Under conditions of tire tread winding, mold extrusion, and high temperature and high pressure vulcanization, they are prone to shearing, extrusion, and pulling, resulting in wire breakage and disconnection. The temperature measurement success rate is less than 85%, affecting the continuity of the test and the integrity of the data. Insufficient positioning accuracy: Temperature measurement points rely on manual experience for estimation, lack standardized three-dimensional spatial reference, and the positioning deviation is greater than 20mm. This makes it impossible to ensure that the temperature measurement points fall on the target winding layer, resulting in distorted temperature data and difficulty in supporting process optimization. Poor adaptability and consistency: The positioning and wiring methods are not compatible with different single-layer thicknesses, number of winding layers and winding trajectories. There is a lack of standardized processes, poor consistency of wiring between different batches and different personnel, and low repeatability of temperature measurement data. Data validation is lacking: the measured temperature data is disconnected from the vulcanization simulation model, making it impossible to verify the data from both sides. The accuracy of the measured data and the precision of the simulation model cannot be verified, and the process optimization lacks scientific support. Control and traceability are difficult: The temperature measuring line lacks a centralized control design, making it prone to tangling, displacement, and misalignment, which exacerbates the risk of temperature measurement deviation and line breakage; after temperature measurement, there is no dissection and traceability benchmark, making it impossible to accurately match the temperature measurement point with the actual floor level, and making data traceability difficult.

[0005] Existing technologies have not developed a closed-loop solution for the entire process of positioning, wiring, temperature measurement, verification, and traceability specifically for the characteristics of the giant tire tread winding process, making it difficult to meet the high-precision production quality control requirements of giant tires. Summary of the Invention

[0006] The technical problem to be solved by the present invention is that the existing methods for temperature measurement wiring of giant tires with tread winding have problems such as high lead wire breakage rate, large temperature measurement point positioning deviation, poor scene adaptability, insufficient data reliability, and difficulty in dissection and traceability. In order to solve the above problems, a three-dimensional precise positioning temperature measurement wiring method for giant tires with tread winding is provided.

[0007] The object of this invention is achieved in the following manner: A method for precise three-dimensional positioning and temperature measurement wiring around a giant tire tread includes the following steps: (1) Preliminary preparation: Determine the number of winding layers, thickness of single layer rubber and winding process according to the design parameters of giant tire tread, plan the number of temperature measuring points, spatial distribution and preset three-dimensional coordinates, and select thermocouples and high-temperature resistant leads connected to the thermocouples. (2) Pre-positioning of bottom layer adhesive lead wires: When the bottom layer adhesive of the tire blank is formed, multiple sets of high temperature resistant lead wires with different lengths are attached to the surface of the bottom layer adhesive and laid out smoothly, and the ends of each lead wire are concentrated in the preset convergence area. The beginning of each lead wire is reserved as the temperature measuring end to be laid to the target winding layer later. (3) Construction of three-dimensional coordinate system: A three-dimensional rectangular coordinate system is established on the upper surface of the bottom rubber. The tread pattern feature line is used as the X-axis reference, the axial extension line of the tire blank is used as the Y-axis reference, and the upper surface of the bottom rubber is used as the Z-axis origin. The Z-axis coordinates of the temperature measurement points of each winding layer are calculated based on the number of winding layers and the thickness of a single layer, so as to determine the preset three-dimensional coordinates of each temperature measurement point. (4) Layered placement and coordinate verification of temperature measuring points: During the continuous winding of the tread, the temperature measuring ends of the corresponding lead wires are placed layer by layer to the preset three-dimensional coordinate position of the target winding layer so that the temperature measuring ends are completely covered inside the rubber material of that layer; at the same time, a high-precision positioning tool is used to verify and calibrate the XY coordinates of the temperature measuring ends in real time to control the actual positioning deviation. (5) Feature line linkage alignment: During the continuous winding process, the tread pattern feature line is moved up to the tread surface layer along with the winding layer, and the feature line is aligned with the tread positioning reference line and the positioning reference of the pot mold to establish a reference for subsequent dissection and traceability. (6) Lead wire lead-out and sealing: The ends of each lead wire after the convergence area is brought out to the outside of the mold through the lead wire hole reserved on the vulcanizing mold, and the lead wire hole is sealed with sealing material. Then the lead wire is connected to the signal input terminal of the intelligent vulcanizing temperature measuring instrument. (7) Vulcanization temperature measurement and data acquisition: The tire blank is vulcanized according to the preset vulcanization process, and the temperature data of each temperature measurement point is collected throughout the process by an intelligent vulcanization temperature measuring instrument. (8) Two-way calibration verification: Import the collected measured temperature data into the pre-established sulfurization simulation model, analyze the fitting degree between the measured temperature rise curve and the simulated temperature rise curve, and when the fitting degree reaches the preset threshold, determine that the measured data and the simulation model have achieved two-way verification, and use the measured data to calibrate the simulation model. (9) Dissection and process optimization: After vulcanization, the characteristic line moved up to the surface of the tread in step (5) is used as the dissection baseline to verify the consistency between the actual position of the temperature measurement point and the preset three-dimensional coordinates. The vulcanization process parameters are optimized by combining the measured temperature data and simulation results.

[0008] As a preferred embodiment, in step (1): the number of winding layers is 4 to 10, the thickness of a single layer of adhesive is 5 to 15 mm; each winding layer is provided with 5 to 15 evenly distributed temperature measuring points, and the lateral and longitudinal spacing between adjacent temperature measuring points is 100 to 400 mm.

[0009] Preferably, in step (1): the thermocouple is a T-type thermocouple or a K-type thermocouple; the temperature resistance range of the high-temperature resistant lead is 180~200℃, the lead diameter is 0.3~0.5mm, and the lead is provided with an insulating sheath with a thickness of 0.5~1mm.

[0010] Preferably, in step (4): the verification accuracy of the high-precision positioning tool is ≤ ±3mm, the actual positioning deviation is ≤ ±3mm; the temperature measuring end is completely placed inside the target winding layer, and the distance between the temperature measuring end and the upper and lower surfaces of the winding layer is ≥ 3mm.

[0011] Preferably, in step (7): the preset vulcanization process includes a steam preheating stage, a high-temperature superheated water stage, and a medium-temperature superheated water stage; wherein, the pressure of the steam preheating stage is 0.6~0.95MPa and the temperature is 165~182℃; the pressure of the high-temperature superheated water stage is 2.9~3.4MPa and the temperature is 165~175℃; and the pressure of the medium-temperature superheated water stage is 2.8~3.4MPa and the temperature is 140~148℃.

[0012] Preferably, in step (8): the preset threshold is a temperature rise curve fitting degree ≥ 95%, and the fitting degree between the measured temperature rise curve and the simulated temperature rise curve is analyzed using the correlation coefficient analysis method.

[0013] Preferably, the continuous winding forming process includes unidirectional continuous winding, reciprocating continuous winding, or bidirectional alternating winding.

[0014] As a preferred embodiment, in step (2): the length difference value of the multiple groups of high-temperature resistant leads with different lengths is pre-calculated and determined according to the Z-axis coordinate of the winding layer where each temperature measuring point is located and the position of the confluence area, so that there is no redundant pulling or tensioning when each lead is laid out in layers.

[0015] Preferably, in step (5): the tire tread positioning reference line is a circumferential line or axial marking line pre-engraved on the surface of the tire tread, and the positioning reference of the pot filling mold is the center line of the lead hole of the upper mold or the mold closing marking line.

[0016] The beneficial effects of this invention are as follows: The invention employs a pre-placed bottom layer adhesive surface and a centralized flow structure, preventing the temperature measuring leads from being squeezed, sheared, or pulled during winding, molding, and vulcanization, achieving a temperature measurement success rate of ≥99%. Through a three-dimensional coordinate system and real-time verification and calibration, the three-dimensional positioning deviation of the temperature measuring point is ≤±3mm, ensuring that the temperature data accurately reflects the vulcanization state of each layer, solving the problem of traditional manual estimation positioning deviations exceeding 20mm. It is compatible with different winding layers, single-layer thicknesses, and various continuous winding processes such as unidirectional continuous winding, reciprocating continuous winding, and bidirectional alternating winding. The standardized process eliminates reliance on personnel experience, ensuring consistency across different batches. By constructing a positioning-temperature measurement-dissection closed loop through feature line linkage alignment, the accuracy of dissection traceability is improved, and the temperature measuring point can be accurately matched with the actual layer after temperature measurement. The fit between measured data and the simulation model is ≥95%, enabling bidirectional verification and model calibration of measured data and vulcanization simulation models, providing scientific support for optimizing vulcanization process parameters and predicting vulcanization defects. Using conventional materials and equipment, it can be directly applied to existing production lines, balancing innovation and engineering practicality. Attached Figure Description
