Description

Technical Field

[0001] This utility model relates to the field of spray technology for testing enameled wires, and in particular to a salt water spray testing device for testing the performance of enameled wires. Background Technology

[0002] Enameled wire, a crucial material widely used in electronic and electrical equipment, directly impacts product quality and stability. During its manufacturing and application, various performance tests are typically conducted to ensure excellent insulation, corrosion resistance, and long-term reliability. Among these tests, the salt spray test, a common environmental tolerance method, effectively simulates the corrosion conditions enameled wire might encounter in a salt spray environment, thereby evaluating its corrosion resistance and insulation protection capabilities.

[0003] Existing salt spray testing devices for enameled wire performance testing generally consist of a spray system, a sample support mechanism, and a control unit. The spray system atomizes salt water through nozzles and sprays it evenly onto the surface of the enameled wire sample. The sample support mechanism is used to fix the position of the enameled wire, and the control unit is used to set the spray parameters to meet different testing standards. However, existing technologies usually rely on simple clamping or suspension methods to fix the enameled wire, which can easily lead to displacement of the enameled wire during spraying, resulting in uneven spraying and affecting the accuracy and consistency of the test results. Therefore, a salt spray testing device for enameled wire performance testing is proposed to solve the above problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3This utility model provides an embodiment of a salt spray testing device for enameled wire performance testing, comprising a spray box 1, a door 2 connected to the front of the spray box 1 via a damping hinge, the door 2 being easy to open and close, and the damping hinge effectively buffering the opening and closing torque, preventing violent impacts to the door and extending the service life of the device; a wire-binding mechanism is provided inside the spray box 1 to standardize and fix the position of the enameled wire to be tested, ensuring that the wire does not move during the test, improving the accuracy and repeatability of the test; a spray assembly is provided inside the spray box 1 to uniformly spray the enameled wire with salt water, simulating corrosion conditions under harsh environments, and evaluating the corrosion resistance of the enameled wire; a filter is slidably connected inside the spray box 1. The screen 14 is used to collect and filter impurities and pollutants generated during the spraying process, ensuring the cleanliness of the brine circulation system, preventing clogging of the nozzles 13, and improving the stability and reliability of the device. A fixing mechanism is provided on the side wall of the spray box 1 to enhance the stability of the screen 14 and facilitate maintenance and adjustment. The wire bundling mechanism includes two fixing rods 3, both fixedly connected inside the spray box 1. A positioning block 4 is fixedly connected to the side wall of the front fixing rod 3, used for initial positioning of the enameled wire to prevent slippage or displacement. Fixing blocks 5 are fixedly connected to the side walls of both fixing rods 3, and a winding rod 6 is fixedly connected to the top of each fixing block 5. The winding rod 6 facilitates wire winding and fixing, and allows for flexible adjustment of the wire bundling shape. The system is designed to adapt to the testing needs of enameled wires of different specifications. The positioning block 4 has a limiting groove 7 inside to further precisely define the position of the enameled wire and prevent vibration during spraying. A rubber pad 8 is fixedly connected inside the positioning block 4 to buffer the direct impact of external forces on the enameled wire and simultaneously secure the wire. The rubber pad 8 is located inside the limiting groove 7. The fixing blocks 5 are staggered and positioned between the positioning blocks 4, effectively improving the stability of the wire bundle and preventing the wire from loosening due to water flow impact. The spray assembly includes a temporary storage box 12 and a spray nozzle 13. A water pump 9 is fixedly connected to the rear wall of the spray box 1. A water pump pipe 10 is fixedly connected to the input end of the water pump 9, and a water pump output pipe 10 is fixedly connected to the output end of the water pump 9. The spray box 12 has an outlet pipe 11 and a temporary storage box 12. The top of the temporary storage box 12 is fixedly connected to the top of the inner wall of the spray box 1. It can temporarily store the extracted and filtered brine and provide a sufficient brine source for the spraying process. The nozzle 13 is set at the bottom of the temporary storage box 12. The nozzle 13 can spray the brine evenly and finely onto the surface of the enameled wire to form an all-round coverage, simulating the salt spray corrosion in the real environment. This allows for a more accurate evaluation of the corrosion resistance and lifespan of the enameled wire in the salt spray environment. The water extraction pipe 10 passes through the side wall of the spray box 1 and extends into the interior. It is used to extract the brine from the bottom of the spray box. One end of the outlet pipe 11 passes through the top of the spray box 1 and extends into the interior of the temporary storage box 12. The outlet pipe 11 is responsible for transporting the extracted brine to the temporary storage box 12.

[0032] Reference Figures 4-5The fixing mechanism includes a limiting rod 17 and a recessed hole 15 inside the filter screen 14, which can effectively realize the positioning and limiting functions of the filter screen 14. A rotating plate 16 is rotatably connected to the side wall of the spray box 1, which improves the flexibility and operability of the equipment during use. The side wall of the limiting rod 17 is slidably connected to the inside of the rotating plate 16 and the side wall of the limiting rod 17 is slidably connected to the inside of the recessed hole 15, ensuring that the limiting rod 17 can be stably positioned and flexibly moved during operation to adapt to the needs of different working states. A pull plate 18 is fixedly connected to one end of the limiting rod 17, which is convenient for manual pulling of the limiting rod to unlock or reset. A spring 19 is sleeved on the outside of the limiting rod 17. One end of the spring 19 is fixedly connected to the side wall of the pull plate 18, and the other end of the spring 19 is fixedly connected to the side wall of the rotating plate 16. Through the elastic reset action of the spring, the limiting rod 17 can be automatically pushed back to the initial position after the external force is released, thereby realizing the rapid self-reset of the structure and improving the continuity and safety of equipment operation.

[0033] Working principle: When using this equipment, first press one end of the enameled wire into the limiting groove 7 on one side. During the pressing process, the rubber pad 8 deforms, fixing one end of the enameled wire. Then, pass the enameled wire through the fixing block 5 in sequence, and press the other end of the enameled wire into the limiting groove 7 on the other side, thus completing the fixing of the enameled wire and ensuring the uniformity of spraying. Then, start the water pump 9 to extract the brine from the spray box 1 and send it into the temporary storage box 12 through the water outlet pipe 11. Finally, spray it out through the nozzle 13, so that the enameled wire at the bottom can fully receive the brine spray. The sprayed brine will drip down and return to the bottom of the spray box 1 after being filtered by the filter screen 14, achieving the effect of recycling. After the work is completed, the filter screen 14 can be disassembled to clean the filtered particulate impurities. By pulling the pull plate 18 to stretch the spring 19, the limiting rod 17 is pulled out from the inside of the concave hole 15, releasing the lock of the filter screen 14. At this time, the filter screen 14 can be removed by the handle. The brine is then drained to ensure the flow rate of subsequent brine.
