Description

Technical Field

[0001] This utility model relates to the technical field of basic performance testing equipment for automotive coating materials. Background Technology

[0002] In recent years, with the rapid development of the domestic automobile industry, consumers not only need to consider the appearance of the interior and exterior trim, such as novel designs, color matching and soft touch, but they also pay great attention to the durability and fatigue resistance of the exterior trim, such as the durability of the upholstery materials of car seats (fabric, genuine leather, synthetic leather, leather, PVC surface, etc.).

[0003] When a car is in motion or undergoes emergency braking, the flexible materials of the seat that come into contact with the person will exhibit noticeable movement, twisting, and arching. These are all visual characteristics that appear during use. Especially under different operating conditions, such as cold winters, hot summers, high temperature and humidity, and dry environments, the lifespan of these flexible materials can be significantly affected, thus impacting the lifespan of the seat.

[0004] Each material can withstand a certain number of repeated uses and maintain its durability while meeting the basic properties of flexible materials, as determined by testing these properties. Currently, there are no official standards, either domestically or internationally, for simulating the durability of automotive flexible materials, and therefore, there is no standardized testing equipment for this type of testing.

[0005] However, the reciprocating extrusion of automotive coating materials to meet the durability test requirements of these materials is also a necessity for OEMs. Therefore, it is necessary to develop a dedicated testing device and corresponding testing standards for the reciprocating extrusion performance of coating materials to provide reliable research basis for manufacturers. Utility Model Content

[0006] The purpose of this invention is to provide a device for testing the reciprocating extrusion performance of automotive coating materials, in order to effectively evaluate the quality of automotive coating materials, addressing the aforementioned limitations of the prior art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A testing device for the reciprocating extrusion performance of automotive coating materials includes a test bench, dual synchronous rails, a servo motor, a left fixed seat, a left fixed rod, a right fixed seat, a right fixed rod, a middle fixed seat, a middle fixed rod, a slide plate, a first support frame, a first movable rod, a second support frame, and a second movable rod. The dual synchronous rails are arranged laterally parallel to each other on the test bench, and the servo motor is the drive mechanism for the dual synchronous rails. The left fixed seat is fixed to the test bench near the beginning of the dual synchronous rails, and the left fixed rod is arranged laterally on the left fixed seat. The right fixed seat is fixed to the test bench near the end of the dual synchronous rails, and the right fixed rod is arranged laterally on the left fixed seat. The middle fixed seat is fixed on the right side; the middle fixed seat is fixed on the test platform, spanning the middle of the dual synchronous rails, and the middle fixed rod is horizontally set on the middle fixed seat; the middle of the slide plate is hollowed out, and the middle fixed seat is located in the hollowed-out space; the left and right ends of the lower panel of the slide plate are respectively connected to the sliders of the dual synchronous rails; the first support frame and the second support frame are respectively fixed on the left and right ends of the upper panel of the slide plate; the first movable rod is horizontally set on the first support frame, and the second movable rod is horizontally set on the second support frame; the axial center lines of the left fixed rod, the right fixed rod, the middle fixed rod, the first movable rod, and the second movable rod overlap, and there is a gap between adjacent ones.

[0009] The aforementioned reciprocating extrusion performance testing device for automotive coating materials also includes an environmental chamber for adjusting the temperature, humidity, and light during testing to simulate test data under actual working conditions.

[0010] Furthermore, multiple sets of fixed rods and movable rods, identical to the left fixed seat, left fixed rod, right fixed seat, right fixed rod, middle fixed seat, middle fixed rod, first support frame, and first movable rod, are sequentially arranged between the two synchronous rails, which can be used to test large-area samples.

[0011] Furthermore, it also includes multiple clamps used to hold the sample during testing.

[0022] The specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosed technical solutions. It should also be noted that, for ease of description, the accompanying drawings show only the parts relevant to the technical solutions of this application, not the entire structure.

[0023] Before discussing the exemplary embodiments in more detail, it should be mentioned that the structure of the device components and / or modules mentioned in the embodiments, unless otherwise described in detail, is something that can be understood by those skilled in the art based on existing public technologies or is a commercially available product.

[0024] refer to Figure 1This embodiment provides a testing device for the reciprocating extrusion performance of automotive coating materials, including a test bench 1, dual synchronous rails 2, a servo motor 3, a left fixed seat 4, a left fixed rod 5, a right fixed seat 6, a right fixed rod 7, a middle fixed seat 8, a middle fixed rod 9, a slide plate 10, a first support frame 11, a first movable rod 12, a second support frame 13, and a second movable rod 14. The dual synchronous rails 2 are arranged horizontally parallel to each other on the test bench 1, and the servo motor 3 is the driving mechanism for the dual synchronous rails 2. The left fixed seat 4 is fixed to the test bench 1 near the beginning of the dual synchronous rails 2, and the left fixed rod 5 is arranged horizontally on the left fixed seat 4. The right fixed seat 6 is fixed to the test bench 1 near the end of the dual synchronous rails 2, and the right fixed rod 7 is arranged horizontally on the right fixed seat 4. The intermediate fixed seat 8 is fixed on the test platform 1, spanning the middle of the dual synchronous rail 2. The intermediate fixed rod 9 is horizontally arranged on the intermediate fixed seat 8. The middle of the slide plate 10 is hollowed out, and the intermediate fixed seat 8 passes through the receiving space formed by the hollowed-out structure. The left and right ends of the lower panel of the slide plate 10 are respectively connected to the slider of the dual synchronous rail 2. The first support frame 11 and the second support frame 13 are respectively fixed on the left and right ends of the upper panel of the slide plate 10. The first movable rod 12 is horizontally arranged on the first support frame 11, and the second movable rod 14 is horizontally arranged on the second support frame 13. The axial center lines of the left fixed rod 5, the right fixed rod 7, the intermediate fixed rod 9, the first movable rod 12 and the second movable rod 14 overlap and are the same horizontal line, with gaps between adjacent ones.

[0025] The dual synchronous linear guide 2 can be selected from existing synchronous belts or chain belts, and is connected to the servo motor 3 through a belt module or sprocket module.

[0026] During testing, samples can be secured using specially configured or existing clamps.

[0027] To accommodate large-area sample testing, multiple sets of fixed rods and movable rods, identical to the left fixed seat 4, left fixed rod 5, right fixed seat 6, right fixed rod 7, middle fixed seat 8, middle fixed rod 9, first support frame 11, and first movable rod 12, can be sequentially set between the dual synchronous rails 2 to facilitate clamping large-sized sample parts and to achieve relatively uniform extrusion.

[0028] For example, by adjusting the temperature, humidity, and light during testing to simulate test data under actual working conditions, the entire device can be placed inside an environmental chamber to operate.

[0029] During testing, the sample is fixed to the rod and the movable rod respectively by clamps. The motor is turned on, and the middle slide moves left and right, driving the movable rod to move back and forth to squeeze and pull the sample. After reaching the preset number of times, the machine is stopped, the sample is removed, and the basic properties of the flexible material are tested.

[0030] Because reciprocating compression directly affects the lifespan of seat materials, especially under different working conditions, such as cold winters, hot summers, high temperature and humidity, and dry environments, the lifespan of flexible materials can be further affected. If it is necessary to simulate different working conditions, testing can be conducted in an environmental chamber to provide a basis for OEM research on the performance of automotive covering materials.

[0031] Simulated reciprocating compression tests can shorten the time, especially under different working conditions, to predict the failure time limit and complete fatigue analysis. It is a relatively accurate, simple, fast and cost-effective method.

[0032] It should be noted that although exemplary embodiments of the technical solution of this patent have been described above, these descriptions should not be interpreted in a limiting sense. On the contrary, those skilled in the art can make various changes and modifications without departing from the scope of the technical solution claimed by this patent as defined in the appended claims.
