Description

Technical Field

[0001] This utility model relates to the field of water-cooled structure technology, specifically to a circulating water-cooled fixed column structure based on high-temperature tensile testing of metal specimens. Background Technology

[0002] The high-temperature tensile testing fixture for metal specimens is a mechanical property test tool for metallic materials in a high-temperature environment. It measures the mechanical properties of the metal under high-temperature conditions, such as yield strength, tensile strength, and elongation, by placing the metal specimen in a specific high-temperature furnace and applying a uniaxial tensile load until the specimen breaks. This test can simulate the performance of metallic materials under actual high-temperature conditions and provide an important basis for the high-temperature strength assessment, engineering design, and quality control of materials. In high-temperature environments, the fixture material can also deform due to thermal expansion, affecting the accuracy and reliability of the test. Cooling can effectively control the temperature at the end of the fixture, reduce thermal expansion, and thus maintain the shape and size stability of the fixture, ensuring the centering and clamping stability of the specimen during the test. In high-temperature tensile testing of metal specimens, in order to avoid burns to personnel from the end of the fixture after the test, the existing technology usually uses water pipes for cooling. Although water cooling can effectively cool the end of the fixture, if we want to improve the uniformity of cooling, a large amount of water will be used, which will increase the waste of water resources. Therefore, to address the above problems, a circulating water-cooled fixed column structure based on high-temperature tensile testing of metal specimens is proposed. Utility Model Content

A clamp assembly 2 is fixedly connected to the bottom of the tensile driving device 1. A water inlet hose 3 is fixedly connected to the front end of the clamp assembly 2.

[0017] As a further implementation of this solution, the solenoid valve 23 is located at the front end near the water passage 25, the valve port of the solenoid valve 23 is aligned with the front end of the water passage 25, and the front end of the solenoid valve 23 is fixedly connected to the inlet hose 3. It should be noted that the position design of the solenoid valve 23 and its alignment with the water passage 25 ensure precise control and guidance of the water flow, thereby improving the efficiency and reliability of the cooling system. Furthermore, this design allows water to enter the cooling zone more directly and evenly, optimizing the cooling effect while reducing water waste and enhancing the energy efficiency of the entire system. As a further implementation of this solution, a channel is provided on the clamp fixing post 21 near the fixed pipe sleeve 29, and the arc-shaped groove 28 of the clamp fixing post 21 is connected to the fixed pipe sleeve 29 through the through hole. The rear end of the fixed pipe sleeve 29 is fixedly connected to the water outlet hose 4, and the inner side of the fixed pipe sleeve 29 is connected to the inner side of the water outlet hose 4. It should be noted that: the channel design of the clamp fixing column 21 and its communication with the fixed pipe sleeve 29 ensure the flow of the cooling medium, making the cooling more uniform and effective. The fixed connection between the fixed pipe sleeve 29 and the outlet hose 4 and the internal communication ensure the flow and uniform distribution of the cooling medium throughout the system. Furthermore, this design helps improve cooling efficiency, reduces the risk of localized overheating, thereby protecting the fixtures and specimens, improving the accuracy and reliability of the test, helping to improve the cooling effect, reducing thermal stress caused by uneven cooling, thereby extending the service life of the equipment and improving the safety of the test; As a further implementation of this solution, the dual channel 26 and the arc-shaped groove 28 are connected. The dual channel 26 is located near the lower end of the arc-shaped groove 28, and the front end of the dual channel 26 is aligned with the air outlet of the fan 24. The water passage 25 is connected to the dual channel 26 and is located at the rear end of the duckbill valve 27. It should be noted that the connection and position design of the dual channel 26 and the arc-shaped groove 28 ensure the flow and uniform distribution of the cooling medium. The duckbill valve 27 can prevent water from flowing out of the dual channel 26 and the arc-shaped groove 28 and causing damage to the fan 24. Furthermore, this design helps improve cooling efficiency, reduces thermal stress caused by uneven cooling, thereby protecting the fixture and specimen, improving the accuracy and reliability of the test, and reducing the risk of local overheating, thus protecting the fixture and specimen and improving the safety and accuracy of the test. As a further implementation of this solution, the limiting base 5 is fixedly connected to the lower end of the clamp fixing column 21 by bolts, and the upper and lower protrusions of the limiting base 5 extend into the assembly groove 22. It should be noted that the fixed connection and protrusion design of the limiting base 5 ensure the stability of the fixture and the limiting of the sample. Furthermore, this design helps improve the accuracy and reliability of the test, reduces errors caused by fixture instability, and thus improves the accuracy of the test results. At the same time, this design also helps protect the safety of operators and prevents burns during operation.

[0018] Workflow: During the high-temperature tensile test of the metal specimen, the metal specimen is heated to the required high temperature, the end of the metal specimen is fixed to the bracket, the bracket is slid into the assembly groove 22, the protrusion of the limiting base 5 is inserted into the assembly groove 22 from bottom to top, and the limiting base 5 is fixedly connected to the clamp fixing column 21 by bolts. The other end of the metal specimen is fixed to the foundation by the bracket. By controlling the contraction of the tensile drive device 1, the clamp fixing column 21 drives the metal specimen to apply tensile force. When cooling the clamp assembly 2, the fixed sleeve 29 is removed, and the waterproof temperature sensor is installed inside the clamp fixing post 21 through the channel of the clamp fixing post 21. The waterproof temperature sensor is electrically connected to the battery and controller and transmits signals via existing Bluetooth technology. The fixed sleeve 29 is then fixed to the clamp fixing post 21 with sealant. The temperature inside the arc-shaped groove 28 is detected by a thermometer. When the temperature is below 25 degrees Celsius, the solenoid valve 23 is closed. At this time, the fan 24 is started to blow air into the dual channel 26. Under the action of air pressure, the rear end of the duckbill valve 27 opens. The duckbill valve 27 acts as a flow limiter to prevent water from damaging the fan 24. At this time, external air is blown into the arc-shaped groove 28 through the dual channel 26, thereby fixing the clamp. The column 21 is used for air cooling. When the temperature exceeds 25 degrees Celsius in the water passage, the solenoid valve 23 opens. The water tank is located at the upper end of the clamp fixing column 21. The water inside the water tank enters the water passage 25 through the water inlet hose 3 and the solenoid valve 23, and then enters the arc-shaped groove 28 through the dual channels 26. The water is blown into the arc-shaped groove 28 by the wind, and the water is dispersed by the collision with the clamp fixing column 21, thus forming water mist. This helps the water mist to be evenly distributed inside the arc-shaped groove 28, reduces water consumption, and improves the cooling effect of the clamp fixing column 21. This not only protects the clamp fixing column 21, but also prevents the operator from being burned when operating the clamp fixing column 21. Based on the above principles, the device changes the traditional method of simply using water cooling. It can achieve air cooling and air-water mixed cooling according to the working conditions. This cooling method can convert liquid water into mist, which not only reduces water utilization but also improves the uniformity of cooling, ensuring the safety of the device and the operators.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
