Description

Technical Field

[0001] This utility model belongs to the field of testing equipment and relates to a hydraulic system tensile testing bench. Background Technology

[0002] In many fields of material performance testing and industrial product quality control, tensile testing, as a fundamental and crucial testing method, is widely used to evaluate the mechanical properties of various materials and products under tensile loads. The hydraulic tensile testing bench, as the core equipment for performing tensile testing, directly affects the accuracy and reliability of the test results.

[0003] Ambient temperature has a significant impact on the mechanical properties of materials.

Traditional test benches cannot accurately simulate different temperature conditions, resulting in test results that cannot fully reflect the performance of materials in actual service environments. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a hydraulic system tensile testing bench that allows for testing in more variable environments.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0021] like Figure 1 As shown in Figure 3, the hydraulic system tensile testing bench includes an equipment platform 1. A testing chamber 2 is fixedly connected to the upper end of the equipment platform 1. Side platform plates 3 are symmetrically fixedly connected to the left and right ends of the testing chamber 2. A heat pump 4 is fixedly connected to the upper end of the side platform plate 3 on the left side, and a cold pump 17 is fixedly connected to the upper end of the side platform plate 3 on the right side. Connecting air outlet plates 5 are symmetrically fixedly connected to the left and right inner walls of the testing chamber 2. The two connecting air outlet plates 5 are respectively connected to the output ends of the heat pump 4 and the cold pump 17. A flexible hose 6 is fixedly connected to the end of the connecting air outlet plate 5 away from the testing chamber 2. A square corrugated sleeve 8 is fixedly connected to the lower end of the equipment platform 1 on the upper side, and a magnetic base plate 9 is fixedly connected to the lower end of the square corrugated sleeve 8.

[0022] A hydraulic actuator 10 is fixedly connected to the upper inner wall of the detection chamber 2, and a pair of symmetrical vertical poles 14 are fixedly connected to the inner end of the detection chamber 2.

[0023] Two vertical poles 14 are symmetrically provided with load-bearing plates 11 on their upper and lower sides at their outer ends, and electrical clamps 12 are fixedly connected to the ends of the two load-bearing plates 11 that are close to each other.

[0024] The magnetic base plate 9 and the load-bearing plate 11 located at the lower end are magnetically connected, and the square corrugated sleeve 8 is located on the outside of the two electrical clamps 12.

[0025] Both hoses 6 extend into the square corrugated sleeve 8, and multiple one-way solenoid valves 7 are fixedly connected to the end of the one-way solenoid valve 7 away from the air outlet plate 5.

[0026] The multiple one-way solenoid valves 7 are equidistantly distributed, and an electrical control panel 15 is fixedly connected to the front end of the equipment platform 1.

[0027] The electrical control panel 15 is electrically connected to multiple one-way solenoid valves 7 via wires, and a transparent door panel 16 is hinged to the front end of the detection chamber 2.

[0028] Before conducting the tensile test, the material to be tested must first be placed between two electrical clamps 12. The output end of the hydraulic actuator 10 moves downward, thereby driving the connected upper load-bearing plate 11 and its electrical clamps 12 to move downward. Under the action of tension, the material to be tested begins to undergo tensile deformation. The tester can observe the deformation of the material and the data recorded by relevant external testing instruments. During the tensile test, in order to simulate the effect of different ambient temperatures on the material's performance, the temperature inside the test chamber 2 needs to be adjusted. The tester controls the heat pump 4 and the cold pump through the electrical control panel 15. 17 sends a start signal. Upon receiving the signal, the heat pump 4 on the left side platform 3 and the cold pump 17 on the right side platform 3 begin to work. The heat pump 4 generates high-temperature, high-pressure gas through refrigerant compression, while the cold pump 17 generates low-temperature, low-pressure gas through a refrigeration cycle. The output ends of the heat pump 4 and the cold pump 17 are connected to the connecting air outlet plates 5 on the left and right inner walls of the detection chamber 2, respectively. The hot and cold gases enter the flexible hoses 6 through the connecting air outlet plates 5. Both flexible hoses 6 extend into the square corrugated sleeves 8. The upper end of the square corrugated sleeves 8 is fixed to the lower end of the equipment platform 1, and the lower end is connected to the load-bearing structure located at the lower end through the magnetic base plate 9. The plate 11 is magnetically connected. When the load-bearing plate 11 moves up and down with the drive of the hydraulic actuator 10, the square corrugated sleeve 8 can move in tandem, always maintaining the enclosure of the two electrical clamps 12 and the space around the material to be tested. This design allows the hot and cold gases output by the heat pump 4 and the cold pump 17 to circulate within the small space defined by the square corrugated sleeve 8, thereby changing the ambient temperature around the material to be tested more quickly to reach the set detection temperature. At the same time, multiple one-way solenoid valves 7 are installed at the end of the hose 6 away from the air outlet plate 5 and are equidistantly distributed. Multiple one-way solenoid valves 7 can be controlled sequentially through the electrical control panel 15. The opening and closing states of the solenoid valve 7 are controlled by the sequential opening of one-way solenoid valves 7 at different positions. Hot and cold gases enter the square corrugated sleeve 8 from different positions, so that the temperature inside the square corrugated sleeve 8 can exhibit different temperature levels within the same equipment start-up time. This simulates a more complex and diverse temperature environment, meeting the tensile testing requirements of the material to be tested under different temperature conditions. The front end of the testing chamber 2 is hinged with a transparent door panel 16. During the entire testing process, the testing personnel can directly observe the deformation, color change, and other physical phenomena of the material to be tested under tensile force and different temperature environments through the transparent door panel 16.

[0029] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
