Description

Technical Field

[0001] This utility model relates to the technical field of rubber testing, and in particular to a thermal aging test device for rubber testing. Background Technology

[0002] In the research and development and quality inspection of rubber materials, heat aging testing is a crucial method for evaluating rubber performance. Traditional rubber heat aging testing equipment typically only provides a single heat aging temperature environment. If it is necessary to test the heat aging performance of rubber under different temperature conditions, it is necessary to change testing equipment multiple times or conduct tests in batches. This not only consumes a significant amount of time and effort, but also, due to inconsistent testing conditions, may affect the accuracy and comparability of the test results. Furthermore, when testing different types of rubber, traditional equipment struggles to avoid potential mutual interference between different rubbers, such as the influence of odors and volatile substances, thus affecting the reliability of the test results. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a heat aging test device for rubber testing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A heat aging test apparatus for rubber testing includes a housing with multiple cavities inside. Multiple threaded sleeves are connected to the housing, each threaded sleeve communicating with a corresponding cavity. Each threaded sleeve is threaded with an electric heating tube. Each cavity contains a matching drawer. Multiple partitions are fixed to the inner walls of each drawer, forming multiple independent spaces with the corresponding drawers. Each drawer contains multiple mesh panels, each mesh panel connected to both the corresponding drawer and the corresponding partition.

[0006] Preferably, the enclosure is equipped with multiple temperature controllers.

[0007] Preferably, a thermometer is installed in each of the multiple drawers.

[0008] Preferably, each of the drawers is equipped with a handle.

[0009] Preferably, each of the multiple sets of cavities is connected to a slide rail at one end and the other end, and each of the multiple sets of drawers is provided with a slide groove at one end and the other end, and the multiple sets of slide grooves are slidably connected to the corresponding slide rails.

[0010] Preferably, the enclosure is made of stainless steel and its inner wall is coated with a heat insulation layer, which can effectively reduce heat loss, improve energy utilization efficiency, and prevent the outside of the enclosure from overheating, thus ensuring the safety of the operators.

[0011] Preferably, the drawers, partitions, and mesh panels are all made of corrosion-resistant and thermally conductive aluminum alloy. This ensures that different types of rubber do not interfere with each other in their independent spaces, and that heat is transferred evenly, ensuring that the rubber is heated consistently during the thermal aging process and improving the accuracy of the experimental results.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Through the coordinated design of the enclosure, cavities, threaded sleeves, electric heating tubes, drawers, partitions, and mesh panels, the multiple cavities within the enclosure are each equipped with electric heating tubes and contain independent drawers. The drawers themselves, with multiple independent spaces created by partitions, can hold various types of rubber. The spaces formed by the partitions and mesh panels can also hold water. Compared to traditional methods, this eliminates the need for multiple equipment changes or batch testing, significantly saving time and effort. For example, previously testing the aging performance of rubber at three different temperatures in batches took a week; the new design can complete this within a day, greatly improving testing efficiency. Simultaneously, the multiple independent spaces within the drawers, created by partitions to hold different types of rubber, and the spaces formed by the partitions and mesh panels to hold water, effectively absorb or block volatile odors and substances from the rubber, reducing interference between different types of rubber. For instance, when testing natural rubber and nitrile rubber, this avoids mutual influence of their odors and volatile substances, improving the reliability of the test results.

[0014] 2. The electric heating element is installed in the housing by means of a threaded sleeve and a threaded connection between the sleeve and the heating element. This threaded connection facilitates installation and disassembly. When the heating element malfunctions and needs replacement, technicians can easily remove the damaged element and replace it with a new one simply by rotating the heating element, saving maintenance time and improving equipment maintenance efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figures 1 to 5 A heat aging test device for rubber testing includes a housing 1, within which multiple cavities 2 are formed. Multiple threaded sleeves 3 are connected to the housing 1, each threaded sleeve 3 communicating with a corresponding cavity 2. Each threaded sleeve 3 is threadedly connected to an electric heating tube 4. This threaded connection not only ensures the stability of the electric heating tube 4 installation but also greatly facilitates subsequent maintenance and replacement. When the electric heating tube 4 malfunctions and needs repair or replacement, technicians can easily remove it from the threaded sleeve 3 by simply rotating it, and replace it with a new electric heating tube 4. The entire process is simple, greatly saving maintenance time and improving equipment maintenance efficiency. Each cavity 2 contains a matching drawer 5. Multiple partitions 6 are fixed to the inner walls of each drawer 5, forming multiple independent spaces. These independent spaces are key areas for placing different types of rubber, effectively preventing interference between different types of rubber. In actual testing, the volatile odors and substances emitted by different types of rubber, such as natural rubber and nitrile rubber, may affect the accuracy of test results. By setting up these independent spaces, each type of rubber can undergo heat aging testing in its own space without interference. Multiple drawers 5 contain multiple sets of mesh panels 7, which are connected to corresponding drawers 5 and corresponding partitions 6. Water can be placed in the space formed by the partitions 6 and the mesh panels 7. The water can absorb or block the volatile odors and substances emitted by the rubber, further reducing mutual interference between different rubbers and improving the reliability of test results.

[0023] In this embodiment, multiple temperature controllers 12 are installed on the housing 1, which can control the temperature of the corresponding electric heating tube 4. Experimenters can flexibly set various temperature values ​​through the temperature controllers 12 according to different testing needs to simulate various complex thermal aging environments. This operation is existing technology and will not be elaborated further. Temperature gauges 11 are installed in each of the multiple drawers 5, enabling real-time monitoring of the temperature in the corresponding cavity 2. During the experiment, experimenters can observe the data displayed on the temperature gauges 11 at any time to promptly grasp temperature changes. If abnormal temperature fluctuations occur, the parameters of the temperature controllers 12 can be quickly adjusted to ensure the temperature remains within the set range, providing a stable temperature environment for the rubber thermal aging test. Handles 10 are connected to each of the multiple drawers 5, and slide rails 8 are connected to one and the other ends of each of the multiple cavities 2. Slide grooves 9 are opened on one and the other ends of each of the multiple drawers 5, and these slide grooves 9 are slidably connected to the corresponding slide rails 8. This design of the slide rails 8 and slide grooves 9 makes the insertion and removal of the drawers 5 smoother, reducing friction and jamming, and further improving the efficiency of the drawers 5 within the cavity 2. Stability is ensured so that drawer 5 will not shake or shift during the heat aging test, thus affecting the test results. The cabinet 1 is made of stainless steel and its inner wall is coated with a heat insulation layer, which can effectively reduce heat loss and improve energy utilization efficiency. At the same time, it can prevent the outside of cabinet 1 from overheating and ensure the safety of operators. Multiple drawers 5, partitions 6 and mesh panels 7 are made of corrosion-resistant and thermally conductive aluminum alloy. This can ensure that different types of rubber do not interfere with each other in independent spaces and can also make heat evenly transferred, ensuring that the rubber is heated evenly during the heat aging process and improving the accuracy of the test results.

[0024] The working principle of this embodiment is as follows: Before conducting the rubber thermal aging test, multiple drawers 5 are removed sequentially, and an appropriate amount of water is poured into each drawer 5, ensuring the water does not overflow the mesh plate 7. After pouring the water, different types of rubber are placed sequentially into the independent spaces formed by multiple partitions 6 within the multiple drawers 5 according to the experimental plan. Each type of rubber corresponds to a specific position to ensure accurate recording and analysis of experimental data. After the rubber is properly placed, the drawer 5 is inserted into the corresponding cavity 2. Next, the electric heating tube 4 is connected to an external power source to provide heat for the entire test. At this time, the temperature controller 12 is used to precisely control the temperature of the corresponding electric heating tube 4, setting different temperature values ​​according to the experimental requirements to simulate various thermal aging environments. Simultaneously, the temperature gauge 11 installed at the drawer 5 will monitor the temperature in the corresponding cavity 2 in real time, allowing the experimenter to observe temperature changes at any time. During the experiment, the experimenter needs to record the data displayed by the temperature gauge 11 regularly to ensure that the temperature remains within the set range. If abnormal temperature fluctuations occur, the parameters of the temperature controller 12 should be adjusted promptly. Every so often, remove drawer 5 and observe the changes in the rubber's appearance, such as color changes or surface cracks, and record these observations in detail. Once the predetermined heat aging time has been reached, turn off the power, remove the rubber, and conduct subsequent performance tests, such as tensile strength and hardness tests. By comparing the rubber's performance with that before aging, accurately assess the changes in the rubber's performance under different heat aging conditions.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
