Description

Technical Field

[0001] This invention relates to the field of thermal spraying technology, and in particular to a device and a method for detecting the impact force of high-speed gas jets during high-frequency focused explosive spraying (hereinafter referred to as explosive spraying), specifically to a device and method for detecting the impact force of high-speed jets in explosive spraying. Background Technology

[0002] Explosive spraying, as an advanced thermal spraying process, is widely used in aerospace, petrochemical, and machinery manufacturing industries due to its ability to produce coatings with high bonding strength and low porosity. It is used to improve the wear resistance, corrosion resistance, high-temperature resistance, electrical conductivity, thermal conductivity, and insulation properties of workpiece surfaces. In explosive spraying, the key technical parameters of the high-speed jet are its velocity and temperature, which are critical factors affecting coating quality. The jet velocity directly affects core performance indicators such as the bonding strength between the coating and the substrate, and the coating density (porosity). The velocity of the high-speed gas jet is influenced by the spray gun structure, the mixed gas components (including coating materials), and the distance between the spray gun and the workpiece. Traditional methods for detecting jet velocity include laser Doppler velocimetry (LDV) and particle image velocimetry (PIV), which are costly, time-consuming, and cannot be integrated into the explosive spraying process.

[0003] Therefore, developing a detection device and method that can directly, in real time, and at low cost detect the energy of explosive spraying gas jets is an urgent problem to be solved by those skilled in the art. This would reduce costs, shorten production and research cycles, and enable explosive spraying technology to be more widely applied to the industries in need. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device and method for detecting the impact force of high-speed jets in explosive spraying, so as to solve the technical problem that existing detection methods cannot detect the impact energy of high-speed jets in explosive spraying in real time, quickly and at low cost.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-speed jet impact force detection device for explosive spraying, comprising: a force sensor, a force sensor mounting bracket, and a data acquisition and processing system; The force sensor is used to detect the impact force of the high-speed gas jet during the explosive spraying process; The force sensor mounting bracket is used to install, protect, and transmit impact force of the force sensor. It includes a mounting base plate, a sensor transition plate, studs, a first locking nut, a hollow round tube, a top panel, a cover plate, a second locking nut, and an impact force bearing cylinder. The force sensor is fixed to the mounting base plate, with its lower surface in contact with the upper surface of the mounting base plate. The sensor transition plate is fixedly connected to the force-measuring end of the force sensor. The stud is connected to the sensor transition plate via a central threaded hole and locked in place by a first locking nut. The upper panel is fixed to the mounting base plate via a hollow tube, and the upper panel and the mounting base plate are parallel, with the distance between them defined by the hollow tube. A gap A is left between the sensor transition plate and the upper panel. The cover plate is fixed to the upper surface of the upper panel, with its central hole coaxially mounted with the stud. A gap C is left between the first locking nut and the cover plate. The impact-bearing cylinder is threaded to the stud via its central threaded hole and locked in place by a second locking nut. A gap B is left between the second locking nut and the cover plate. The data acquisition and processing system is electrically connected to the force sensor and is used to acquire, transmit, process and analyze the impact force signal output by the force sensor.

[0006] Furthermore, the force sensor is fixed to the mounting base plate by three first hexagon socket bolts; the sensor transition plate is fixedly connected to the force measuring end of the force sensor by three second hexagon socket bolts; the upper panel is fixed to the mounting base plate by four hollow round tubes and corresponding third hexagon socket bolts; and the cover plate is fixed to the upper surface of the upper panel by two fourth hexagon socket bolts.

[0007] Furthermore, the sensor transition plate has a threaded hole at its center, and the center of the threaded hole is coaxially mounted with the center of the force sensor.

[0008] Furthermore, the gaps A and B are ≥3mm, and the gap C is ≥3mm.

[0009] Furthermore, the outer diameter of the impact-bearing cylinder is 3-5 mm larger than the diameter of the coating spot (the main effective range / area of ​​the gas jet) and more than 10 mm larger than the inner diameter of the cover plate.

[0010] Furthermore, the force sensor is a high-frequency dynamic force detection sensor, which can withstand temperatures of not less than 100℃, has a range of 0-50kgf, and a response frequency of not less than 1kHz. It can quickly respond to changes in jet impact force and ensure real-time detection.

[0011] Furthermore, the data acquisition and processing system includes a data acquisition card, a computer, and dedicated data processing software. The input end of the data acquisition card is connected to the force sensor via a shielded cable, and the output end is connected to the computer via a USB data cable. The data acquisition card is powered by a power adapter.

[0012] Furthermore, the sampling frequency of the data acquisition card can be set by computer software, with a setting range of 1000Hz-156000Hz. The sampling frequency can be flexibly adjusted according to actual detection needs to meet different detection accuracy requirements. The dedicated data processing software has functions such as real-time data display, data storage, signal filtering, peak impact force extraction, and impact force-time correlation curve plotting.

[0013] This invention also provides a method for detecting the impact force of high-speed jets in explosive spraying, comprising the following steps: S1: Equipment installation and debugging: Fix the force sensor to the force sensor mounting bracket, then fix the force sensor mounting bracket to the explosion spraying workbench, cover and protect the sensor cable and connect it to the data acquisition card, connect the data acquisition card to the computer and power it on; S2: Parameter setting: Set the acquisition frequency and sensor range through the data acquisition and processing system, set the mixed gas composition parameters of the explosive spraying equipment, and adjust the relative position of the explosive spray gun and the force sensor. S3: Zero-point calibration: The force sensor is zeroed through the data acquisition and processing system; S4: Impact force detection: Start data acquisition, control the explosive spraying equipment to move above the sensor, stay for 2-3 seconds, then move it away, and then stop data acquisition; S5: Data and Performance Analysis: Check the collected data and generated curves, detect the bonding strength and porosity of the explosive sprayed samples, and establish the correspondence between the mixed gas components, the distance between the spray gun and the sensor, the jet impact force and the coating quality (sample bonding strength and porosity).

[0014] Furthermore, fixing the force sensor to the force sensor mounting bracket specifically includes: The force sensor is fixed to the mounting base plate by three first hex socket bolts, with the force sensor terminals facing the long axis of the mounting base plate. The transition plate is fixed to the force measuring end of the force sensor by three second hex bolts. The stud is screwed into the center screw hole of the transition plate and the first locking nut is tightened. The top panel is fixed to the mounting base plate using four hollow round tubes and corresponding third hex bolts, ensuring they remain parallel. The cover plate is fixed to the top plate with two fourth hex bolts, ensuring that the center hole of the cover plate is coaxial with the stud. Finally, the second locking nut and the impact bearing cylinder are connected to the stud by threads and locked.

[0015] Furthermore, the jet impact force transmission process is as follows: the gas jet acts directly on the impact force bearing cylinder, is transmitted to the sensor transition plate through the stud, is then transmitted to the force measuring end of the force sensor, and finally to the sensor fixing end and the mounting base plate.

[0016] Furthermore, the mixed gas component parameters are the volume ratio of propane to oxygen, and the relative position of the explosion spray gun and the force sensor is specifically as follows: the height of the spray gun head from the sensor is 60-120mm, and the center of the spray gun is aligned with the center of the impact force bearing cylinder.

[0017] Furthermore, step S4 includes: if there are abnormalities in the collected data, analyze the cause of the abnormality and resolve it, and repeat steps S2-S4; the correspondence established in step S5 is used for optimization of explosive spraying process parameters and coating quality control.

[0018] Compared with the prior art, the present invention has the following beneficial effects: This invention is based on the principle of momentum conservation (ΔM*V=F*t), and replaces the detection of jet velocity V by detecting the impact force F of the high-speed gas jet during explosive spraying. The explosive spraying high-speed jet impact force detection equipment and method of this invention can directly detect the impact force of the high-speed gas jet during explosive spraying, eliminating the need for indirect detection and calculation to obtain impact energy data, resulting in more intuitive and accurate detection results. Simultaneously, it can collect, display, and analyze impact force data in real time, promptly reflecting the dynamic changes in jet impact force and avoiding the lag in detection results. Furthermore, the detection equipment has a simple structure and low cost, significantly reducing the quality control cost of explosive spraying technology, shortening production and research cycles, and enabling more widespread application of explosive spraying technology to the required industries, possessing broad application prospects and high practical value.

[0027] The force sensor 1 is fixed to the mounting base plate 2, with its lower surface in contact with the upper surface of the mounting base plate 2. The sensor transition plate 4 is fixedly connected to the force measuring end of the force sensor 1.

[0030] The data acquisition and processing system is electrically connected to the force sensor 1 and is used to acquire, transmit, process and analyze the impact force signal output by the force sensor 1.

[0031] In a preferred embodiment, the data acquisition and processing system includes a data acquisition card, a computer, and dedicated data processing software, such as... Figure 3 As shown in Figures b and c, the input end of the data acquisition card is connected to the force sensor 1 via a shielded cable, which can effectively reduce external electromagnetic interference and ensure the accuracy and reliability of the acquired impact force signal. The data acquisition card is used to acquire the impact force signal output by the force sensor 1. The output end is connected to the computer via a USB data cable, and the data acquisition card is powered by a power adapter. The computer is connected to the output end of the data acquisition card via a data cable to receive the data transmitted by the data acquisition card, providing hardware support for subsequent data processing and analysis.

[0032] The sampling frequency of the data acquisition card can be set by computer software, with a setting range of 1000Hz-156000Hz.

[0033] The dedicated data processing software features real-time data display, data storage, signal filtering, peak impact force extraction, and impact force-time correlation curve plotting. In terms of data display, it can display the collected impact force data in real time, allowing operators to intuitively understand the changes in jet impact force.

It can also extract peak values ​​to obtain peak impact force data and establish a correlation curve between impact force and time, intuitively reflecting the dynamic changes in high-speed jet impact force, providing strong data support for analyzing the explosive spraying process.

[0034] In a preferred embodiment, the present invention also employs the aforementioned equipment for detecting the impact force of high-speed jets used in explosive spraying. The force sensor is a high-frequency dynamic force sensor of a certain brand, with a temperature tolerance of not less than 100℃, a measurement range of 0-50 kgf, and a response frequency of 1 kHz. The data acquisition card is a certain model, with a sampling frequency set to 13 kHz. It is connected to the force sensor via a shielded cable and to a computer via a USB data cable. The dedicated data processing software is self-developed and has functions for real-time data display, storage, filtering, peak extraction, and impact force-time curve plotting. The steps are as follows: (1) Fix the installed sensor and mounting bracket on the explosion spraying workbench. When fixing, ensure that the bracket is stable to avoid displacement during the detection process. At the same time, cover and protect the sensor cable to prevent the cable from being damaged by high temperature, splashes, etc. during the explosion spraying process. Then connect the other end of the sensor cable to the corresponding interface of the data acquisition card to ensure reliable connection.

[0035] (2) Connect the communication cable to the corresponding interface of the data acquisition card and the computer to establish a communication connection between the data acquisition card and the computer, and prepare for data transmission.

[0036] (3) Turn on the computer, power the data acquisition card, and after the device starts up and stabilizes, enter the computer data acquisition and processing platform system to ensure that the system runs normally.

[0037] (4) On the data acquisition and processing system platform, set parameters such as data acquisition frequency and sensor range according to actual detection needs. The parameter settings must be accurate and reasonable to ensure the effectiveness and accuracy of the detection data.

[0038] (5) Before sampling begins, the sensor must be reset to "0" through the platform interface to eliminate the initial error of the sensor and ensure that the detection starting point is accurate.

[0039] (6) According to the process requirements of explosive spraying, set the relevant parameters of the explosive spraying equipment. After the parameters are set, set the relative positions between the explosive spraying equipment and the sensor, that is, determine the height of the explosive spray gun head from the sensor and the position of the sensor measurement center, so as to ensure that the high-speed jet sprayed by the spray gun can accurately act on the detection part of the sensor.

[0040] (7) After completing the above preparations, manually start the test equipment to begin sampling, and the data acquisition system enters the data acquisition state.

[0041] (8) Start the explosive spraying equipment, control the explosive spraying equipment to move above the sensor, and stay above the sensor for 2-3 seconds to allow the high-speed jet to fully act on the sensor, and then move the explosive spraying equipment away.

[0042] (9) After the explosive spraying equipment is removed, the sampling operation is ended and the explosive spraying equipment is turned off.

[0043] (10) On the data acquisition and processing system platform, check the acquired data and generated charts to determine whether the data is complete and reasonable. If there are any abnormalities in the data, the reasons need to be analyzed and the test needs to be repeated.

[0044] (11) Test various properties of the explosive sprayed sample, including the performance indicators such as bonding strength and porosity, and obtain relevant data on coating quality.

[0045] (12) Based on the collected data on mixed gas components, distance between the spray gun and the workpiece, jet impact force, and coating quality inspection data, establish the correspondence between mixed gas components, distance between the spray gun and the workpiece, jet impact force, and coating quality (bonding strength, porosity). This correspondence can be used to guide the optimization of explosive spraying process parameters, improve coating quality, and provide a basis for quality control of explosive spraying process.

[0046] (13) Example of high-speed jet impact force test for explosive spraying: A WC-12Co (15-45μm) coating was prepared on a TC4 substrate. All parameters were kept constant, and only the distance between the spray gun and the workpiece was changed. Three sets of test pieces were made for comparative analysis. The detailed parameters are shown in Table 1. The impact force was the largest at a distance of 60mm, while the coating performance was the best at a distance of 90mm. It can be seen that the best performance does not correspond to the maximum impact force. The jet impact force gradually decreased with the increase of distance, indicating that the maximum impact force was near the nozzle. After the gas mixture exploded, it was fully accelerated in the gun barrel and the nozzle exit velocity reached the fastest. After exiting the nozzle, the air resistance forced the gas jet velocity to gradually decrease until it reached "0" (if the free range is long enough). The acceleration and heating process of the coating material particles in the gun barrel did not make its velocity and temperature reach the optimal level. After exiting the nozzle, the acceleration and heating of the coating material continued until 90mm was the optimal level (only for WC-12Co (15-45μm) material). Therefore, the results in Table 1 are as follows.

[0047] Table 1: Test results of WC-12Co (15-45 μm) coatings prepared on TC4 substrate Note: The bonding strength value is not the actual coating bonding strength, but the value of the bonded surface detachment in the tensile test specimen.

[0048] As can be seen from the above embodiments, the detection equipment and detection method of the present invention can effectively detect the impact force of high-speed jets in explosive spraying, and can establish the correspondence between process parameters, impact force and coating quality, providing a reliable basis for the optimization and quality control of explosive spraying process.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
