Description
Technical Field
[0001] The present application relates to the technical field of aging detection of rubber parts for doors and windows, and in particular to a device for simulating aging testing of rubber parts. Background Art
[0002] With the development of modern industry, the application of various materials is becoming increasingly widespread across various industries. In the transportation sector, rubber parts are particularly used in vehicle doors, windows, seals, and other components. The durability and stability of these rubber parts are directly related to the product's service life and safety. Therefore, testing the aging performance of rubber parts is a crucial step in ensuring product quality.
[0003] Traditional aging testing for rubber parts typically utilizes aging chambers to simulate the environmental conditions experienced by rubber parts during long-term use. This is particularly true through hot air aging and heat resistance testing to assess performance changes. These chambers primarily rely on heating elements to simulate temperature fluctuations in the environment, which in turn triggers aging in rubber parts. However, existing aging chambers have limitations, primarily due to poor internal airflow, which results in uneven heat distribution during the heating process. This uneven heating results in significant variations in the aging process across different parts of the rubber part, making it difficult to accurately reflect the aging behavior of the rubber part in actual use, thus compromising the accuracy and reliability of the test results.
[0004] Especially in subway vehicles, the sealing performance of door and window rubber components is crucial to maintaining a safe interior environment. The operating environment of subway vehicles differs significantly from laboratory aging testing conditions. For example, temperature, humidity, and external factors (such as UV rays and vibration) can accelerate the aging of rubber components. Therefore, traditional aging chambers cannot effectively simulate the aging process of subway vehicle rubber components under actual operating conditions, resulting in significant deviations in rubber component aging assessments.
[0005] In order to overcome the above problems, it is necessary to design a new detection device that can more accurately simulate the aging process of rubber parts in complex environments such as subways, more realistically reproduce the aging conditions of rubber parts, and provide more accurate test data, thereby more effectively evaluating the service life and replacement cycle of rubber parts. Summary of the Invention

[0014] By adopting the above technical solution, the motor drives the lead screw to rotate, causing the two fans to reciprocate in opposite directions, ensuring that the airflow is evenly distributed in the aging chamber. The staggered reciprocating motion of the fans effectively avoids airflow unevenness and improves test accuracy. In addition, the reciprocating motion of the fans, combined with ultraviolet light and thermal airflow to simulate a variety of aging conditions, can adapt to the testing needs of different types of rubber parts.

[0017] In a specific possible implementation manner, the ultraviolet lamp group includes a plurality of ultraviolet lamps, and the plurality of ultraviolet lamps are evenly distributed along the height direction of the aging chamber and are slidably connected to the aging chamber.
[0018] By adopting the above technical solution, the required ultraviolet irradiation intensity is determined according to the needs of the item to be tested. By adjusting the number of ultraviolet lamps, the irradiation intensity can be increased or decreased. After the number is determined, the ultraviolet lamps are installed in the aging chamber through a sliding connection. The sliding connection design and the adjustable number of ultraviolet lamps make the adjustment of the ultraviolet lamps more flexible and convenient, allowing the tester to accurately control the ultraviolet irradiation conditions according to different needs and item characteristics to achieve the most suitable aging test effect.

DETAILED DESCRIPTION
[0039] The rubber aging simulation test device of the present application improves the accuracy and practicality of the test by optimizing the heating, ultraviolet simulation and airflow disturbance mechanisms. The structure and working principle of the present invention are described in detail below with reference to the accompanying drawings and specific implementation schemes.
[0040] Reference Figure 1 and Figure 2 The present application discloses a rubber part aging simulation test device, comprising: Aging chamber 1 is provided with an opening and a hinged door 101. The door 101 can be easily opened during operation to facilitate the placement or removal of the rubber part to be tested. After the test is completed, the opening is tightly sealed to ensure the stability of the internal environment of the aging chamber 1, prevent external factors such as temperature, humidity or light from interfering with the test results, and ensure the accuracy of the test data; The placement component 4 is provided inside the aging chamber 1 and is used to support and fix the rubber parts to be tested, ensuring that the rubber parts are stable and do not move during the aging process to avoid affecting the test results due to position changes. In this embodiment, the rubber parts include but are not limited to vehicle door and window rubber parts; The UV component 3 is provided in the aging chamber 1 and is arranged along the peripheral side of the placement component 4, and is used to irradiate the rubber parts to simulate the aging effect of ultraviolet rays on the rubber parts; The heating component 2 is in communication with the interior of the aging chamber 1 and is used to introduce hot air flow into the aging chamber 1 to simulate the aging of the rubber parts in a high temperature environment; The air flow disturbance mechanism is provided in the aging chamber 1. By disturbing the air flow, the hot air flow is ensured to be evenly distributed in the aging chamber 1, thereby avoiding overheating or uneven temperature in certain areas and ensuring the consistency of the test environment. The controller 102 works in conjunction with the UV component 3, the heating component 2, and the airflow disturbance mechanism through electrical connections, and can adjust parameters such as temperature, UV light, and airflow in real time, simplifying the operating steps during the test process and allowing testers to more conveniently set, monitor, and adjust test conditions; During operation, the operator opens the chamber door 101, places the vehicle door and window rubber parts on the placement component 4 through the opening, ensures that they are stable and in the designated position in the aging chamber 1, and closes the chamber door 101 to form a closed space; then, the operator sets the aging parameters such as temperature, UV intensity, airflow speed, etc. through the controller 102, and controls the UV component 3, heating component 2 and airflow disturbance mechanism to work according to the set conditions; During the aging test, the UV component 3 simulates the aging effect of ultraviolet rays on rubber parts. It accelerates the aging process of rubber by generating ultraviolet radiation, simulating the situation of long-term exposure to the vehicle's outdoor environment. During this process, the heating component 2 introduces hot air into the aging chamber 1 to simulate the performance changes of rubber parts in a high-temperature environment. The hot air flow can be transmitted through a piping system or other conduction methods. At the same time, the air flow disturbance mechanism is activated to ensure the uniform distribution of the hot air flow in the aging chamber 1 to avoid the existence of local areas with excessively high or low temperatures, thereby preventing errors in the test and ensuring consistent aging effects in various parts. After completing the above environmental simulation, various tests on the rubber parts can be carried out, including physical properties after aging, the impact of ultraviolet rays on the material, etc.
[0041] Reference Figure 2 and Figure 3 The placement assembly 4 includes a horizontally arranged movable base 401, a bracket 402 and a movable frame 404. The movable base 401 is mounted on the inner bottom wall of the aging chamber 1 and is slidably connected to the aging chamber 1 to facilitate the placement and removal of rubber parts. In this embodiment, the movable base 401 is slidably connected to the aging chamber 1 via a slide rail. Bracket 402 is fixedly mounted on movable base 401 and has a hollow structure, on which the rubber member is placed. The hollow structure allows the rubber member to be exposed to more air circulation, which helps to evenly heat or dissipate heat. This helps to maintain the uniformity of the rubber member during the aging test and prevent localized excessive temperature from interfering with the test results. The movable frame 404 is provided with a support rod and is movably mounted on the movable base 401 via the support rod. A space for accommodating the rubber member is formed between the movable frame 404 and the bracket 402. The movable frame 404 is provided with a plurality of fixing wires 405. In this embodiment, the plurality of fixing wires 405 are evenly distributed along the length of the movable frame 404. The fixing wires 405 are used to press-fit and fix the rubber member to the bracket 402. During operation, the chamber door 101 is opened, and the operator moves the movable seat 401 out of the aging chamber 1 by sliding it, and lifts the movable frame 404 to open the accommodation space between it and the bracket 402 to provide enough space for placing the rubber parts. At this time, the operator ensures that the movable frame 404 is in an operable position to facilitate the placement of the rubber parts, and places the rubber parts on the bracket 402. After the rubber parts are placed, the movable frame 404 is lowered so that the multiple fixing lines 405 of the movable frame 404 evenly press and fix the rubber parts on the bracket 402, and then the movable seat 401 is pushed back into the aging chamber 1 to ensure that the rubber parts are within the ultraviolet irradiation range in the aging chamber 1 for aging test; During this process, the operator can quickly complete the placement and fixation of the rubber parts by simply sliding the movable seat 401, lifting and lowering the movable frame 404, etc., thereby simplifying the operation process, improving work efficiency, and reducing operation time and complexity; and the rubber parts are crimped and fixed on the bracket 402 through multiple fixing lines 405, ensuring that the rubber parts will not be displaced due to other factors (such as vibration, airflow, etc.) during the aging test, thereby ensuring the accuracy and stability of the test; while fixing the rubber parts, the design of the fixing lines 405 allows the rubber parts to be exposed to a larger air circulation environment, thereby accelerating the aging process of the rubber parts, ensuring that the rubber parts are evenly exposed under ultraviolet radiation, and enhancing the comprehensiveness of the test.
[0042] Reference Figure 4 The UV assembly 3 includes two sets of UV lamps, which are located on both sides of the placement assembly 4 and are installed on two opposite inner walls of the aging chamber 1. By installing the UV lamps on both sides of the aging chamber 1, each set of lamps illuminates a different part of the object to be tested, thereby providing multi-angle UV irradiation, so that all parts of the surface of the object to be tested can be evenly irradiated. In this embodiment, the ultraviolet lamp group includes several ultraviolet lamps 301, and the several ultraviolet lamps 301 are arranged along the length direction and evenly distributed along the height direction of the aging chamber 1. The ultraviolet lamps 301 are slidably connected to the aging chamber 1. In this embodiment, the aging chamber 1 is provided with a slide groove for installing the ultraviolet lamps 301; in actual use, the required ultraviolet irradiation intensity can be determined according to the needs of the items to be tested. By adjusting the number of ultraviolet lamps 301, the irradiation intensity can be increased or decreased. After determining the number, the ultraviolet lamps 301 are installed in the aging chamber 1 by sliding connection; the sliding connection design and the adjustable number of ultraviolet lamps 301 make the adjustment of the ultraviolet lamps 301 more flexible and convenient, and have strong adaptability, so that the tester can accurately control the ultraviolet irradiation conditions according to different needs and item characteristics to achieve the most suitable aging test effect.
[0043] Reference Figure 4The UV component 3 also includes a diffusion cover 303 arranged on the outside of the UV lamp group. The diffusion cover 303 is installed vertically and completely covers the UV lamp group to evenly diffuse the UV radiation; the diffusion cover 303 is slidably connected to the aging chamber 1 through the fixing frame 302. In this embodiment, the fixing frame 302 is fixed on the inner top wall of the aging chamber 1, and the fixing frame 302 is provided with a groove. The diffusion cover 303 can slide in and out of the groove and can be abutted and fixed in the groove; the design of the diffusion cover 303 can evenly diffuse the light emitted by the UV lamp group, avoid the problem of uneven UV intensity, and ensure that all areas on the surface of the object to be tested can be uniformly irradiated with UV rays, thereby better simulating the aging process of the object in a long-term UV exposure environment; and the diffusion cover 303 is slidably connected to the aging chamber 1 through the fixing frame 302, and the diffusion cover 303 can be easily installed and removed, so that the user can quickly replace or maintain it, thereby improving the convenience and maintenance efficiency of the diffusion cover 303.
[0044] Reference Figure 5 The heating assembly 2 includes a heater 201 and an air duct 202. The heater 201 is installed on the outer top wall of the aging chamber 1, and the air duct 202 is installed on the inner top wall of the aging chamber 1. The air duct 202 is arranged horizontally and extends along the length direction of the aging chamber 1. The heater 201 is connected to the air duct 202 through a connecting pipe; the hot air flow is transported into the aging chamber 1 through the heater 201 and the air duct 202, and the hot air flow diffuses along the length direction of the air duct 202 to ensure that the temperature in the entire aging chamber 1 is uniform. The heater 201 can quickly heat the external air to a preset temperature, and transport the hot air flow into the aging chamber 1 through the air duct 202, so that the surface of the rubber part is evenly heated; ensure that the aging chamber 1 can quickly reach the set temperature, thereby speeding up the test process, shortening the aging time of the rubber part, and improving the test efficiency.
[0045] Reference Figure 5 The air flow disturbance mechanism includes a reciprocating moving part and two fans 206. The reciprocating moving part includes a motor 205 and two lead screws 203. The motor 205 is installed outside the aging chamber 1. The two lead screws 203 are respectively arranged on both sides of the air duct 202 and are arranged along the setting direction (length direction) of the air duct 202. The two lead screws 203 are rotatably arranged in the aging chamber 1. One end of the two lead screws 203 passes through the aging chamber 1, and one of the lead screws 203 is connected to the motor 205. The two lead screws 203 are connected through a pulley 204. The fans 206 are respectively installed on the two lead screws 203 and move along the axial direction of the lead screws 203. The two fans 206 reciprocate in opposite directions on the lead screws 203. During operation, the motor 205 is started, and the motor 205 drives a screw 203 connected thereto to rotate, and the screw 203 drives another screw 203 to rotate through the pulley 204. Due to the structural characteristics of the screw 203, the fan 206 installed on the screw 203 reciprocates along the axis direction of the screw 203. The two fans 206 reciprocate in opposite directions. The staggered reciprocating motion of the fans 206 promotes air flow, so that the hot air flow is evenly distributed in the aging chamber 1, thereby ensuring that the rubber parts are affected by a balanced temperature and air flow. During this process, the motor 205 drives the lead screw 203 to rotate, causing the two fans 206 to reciprocate in opposite directions, ensuring that the airflow is evenly distributed in the aging chamber 1. The staggered reciprocating motion of the fans 206 effectively avoids the unevenness of the airflow, thereby ensuring that the rubber parts are subjected to balanced airflow and temperature effects during the aging process, thereby improving the accuracy of the test; and, through the reciprocating motion of the fans 206, combined with ultraviolet rays and hot air flow to simulate a variety of aging conditions, it is possible to adapt to the testing requirements of different types of rubber parts. Users can adjust the movement cycle, wind speed and ambient temperature of the fans 206 according to actual needs, making the equipment more applicable and capable of conducting more comprehensive aging tests.
[0046] The implementation principle of the embodiment of the present application is as follows: during operation, the operator opens the chamber door 101, slides the movable seat 401 out of the aging chamber 1, lifts the movable frame 404, and opens the accommodation space between it and the bracket 402 to provide sufficient space for placing the rubber parts. The vehicle door and window rubber parts to be tested are placed on the hollow structure of the bracket 402 to ensure that the rubber parts are stable and in the specified position. The movable frame 404 is lowered to ensure that multiple fixing lines 405 are evenly pressed and fixed to the bracket 402 to prevent the rubber parts from shifting during the aging process. During the aging test, the operator adjusts the relevant parameters of the aging chamber 1, such as temperature, UV intensity, air flow rate, etc., through the controller 102. According to the test requirements, the operator selects the appropriate UV irradiation intensity and time, as well as the appropriate temperature and air flow rate to ensure that the aging process meets the standards; Start the ultraviolet component 3, and the ultraviolet lamp group begins to irradiate the rubber parts, simulating the aging effect of ultraviolet rays on the rubber parts, ensuring that all parts of the rubber parts are evenly irradiated, and avoiding errors caused by uneven irradiation; start the heating component 2, and deliver hot air to the aging chamber 1 through the heating machine 201 and the air duct 202, simulating the effect of a high temperature environment on the rubber parts, and ensuring that the temperature of the entire aging chamber 1 is evenly distributed; at the same time, start the air flow disturbance mechanism, and the two fans 206 start to move back and forth in opposite directions driven by the lead screw 203. The staggered reciprocating motion of the fans 206 promotes air flow, ensuring that the hot air flow is evenly distributed in the aging chamber 1, and avoiding interference of local temperature unevenness on the test results; during the aging test process, the operator can monitor the temperature, ultraviolet intensity and airflow status in the aging chamber 1 in real time, and adjust the parameters through the controller 102 to ensure a stable aging environment; After the test is completed, the operator turns off the ultraviolet component 3 and the heating component 2, stops the airflow disturbance mechanism, and ends the aging test; opens the door 101 of the aging chamber 1, uses the moving seat 401 to move the rubber part under test out of the aging chamber 1, and the operator carefully removes the rubber part for subsequent physical property and ultraviolet aging effect testing.
[0047] The aging simulation test device of the present application effectively improves the uniformity and stability of the test environment by optimizing the heating, UV simulation, and airflow disturbance mechanisms, ensuring the accuracy of the rubber part aging test. The closed design of the aging chamber 1 can prevent interference from external factors, simulate the aging effects of long-term UV exposure and high temperature environment on rubber parts, and greatly improve the reliability of the test results. In addition, the innovative combination of placement component 4, UV lamp group and heating component 2 allows the rubber parts to be evenly heated and exposed to UV radiation, thereby effectively accelerating the rubber aging process; the airflow disturbance mechanism ensures uniform airflow distribution in the aging chamber 1 through the staggered reciprocating movement of fans 206, avoiding testing errors caused by uneven temperatures; the overall design simplifies the operating process, improves work efficiency, and provides a more comprehensive and accurate solution for aging testing of various rubber parts.
