Description

Technical Field

[0001] The invention relates to the field of tensile testing equipment, in particular to a tensile testing device with a constant temperature working environment. Background Art

[0002] Tensile testing with a constant temperature working environment means that during the tensile test, the temperature of the test environment is controlled to ensure stable test conditions in order to obtain accurate and reliable test data. This test method is usually used in applications where the mechanical properties of materials need to be evaluated under specific temperature conditions.

[0003] In existing devices of this type, the tensile testing machine is usually set in a constant temperature control chamber, and the tensile test space is moved to the constant temperature chamber to realize the operation of performing the tensile test in a constant temperature working environment. However, at the beginning of the test or during the experiment, the operator is usually required to open the sealed door of the constant temperature chamber, set the test sample (set the sample at the beginning and replace the sample during the process), and then close the sealed door after the setting is completed. The sample setting is inconvenient, resulting in a long time for the sealed door to be opened, and the internal temperature of the constant temperature chamber affects the ambient temperature. In subsequent tests, it is necessary to wait for the temperature in the constant temperature chamber to return to the specific range required for the test, which affects the test efficiency. In addition, the temperature in the constant temperature chamber is disturbed, which will inevitably lead to errors in the test data and affect the accuracy of the test data.

[0004] Therefore, a tensile testing device with a constant temperature working environment has been developed, which can reduce the opening time of the sealed door in a constant temperature working environment and ensure the temperature stability of the constant temperature working environment to the greatest extent.

An isolation furnace 5 is connected to the lower part of the loading system 2. A temperature control module 501 is provided on the right side of the isolation furnace 5. The front and rear sides of the isolation furnace 5 are rotatably connected to a sealing door 6. A handle is provided on the sealing door 6 for grasping and opening and closing the sealing door 6. A fixed column 7 is connected to the bottom of the isolation furnace 5. A lock 8 is connected to the bottom of the tension detection component 301 and the top of the fixed column 7. A lock is slidably provided on the lock 8. Pin 801, the lock 8 controls the lock pin 801 to move, the left side of the isolation furnace 5 is rotatably connected to the rotating wheel 9, the upper left part of the isolation furnace 5 is connected to the motor 10, the output shaft of the motor 10 is connected to the rotating wheel 9, the rotating wheel 9 is connected to the electric push rod 15, the telescopic end of the electric push rod 15 is connected to the docking frame 16, the docking frame 16 is clamped with the lower docking piece 13, the top of the lower docking piece 13 is clamped with the upper docking piece 14, the upper docking piece 14 and the lower docking piece 13 are both connected with a clamp 12, the clamp 12 is connected with a locking seat 11, the locking seat 11 is clamped with the lock 8, a magnetic stone 1601 is arranged inside the docking frame 16, the magnetic stone 1601 is magnetically matched with the lower docking piece 13, and the pull A fixed frame 17 is connected to the force detection component 301 and the fixed column 7, and a pushing column 18 is slidably connected to the fixed frame 17. A spring 19 is provided between the pushing column 18 and the fixed frame 17, and the pushing column 18 is squeezed and matched with the clamp 12 under the action of the tensioning force of the spring 19. A winder 20 is connected to the upper side of the interior of the isolation furnace 5, and an isolation curtain 21 is provided on the winder 20. The inner sides of the front and rear parts of the isolation furnace 5 are connected to limit strips 22, and the limit strips 22 are slidably connected to the isolation curtain 21. A vertical frame 23 is connected to the top of the isolation furnace 5, and the front and rear parts of the vertical frame 23 are connected to dampers 24. A protective cover 25 is connected between the telescopic ends of the damper 24, and a cooling fan 26 is connected to the protective cover 25.

[0031] When the present invention is in use, the temperature inside the isolation furnace 5 is regulated by the temperature control module 501 to control the temperature within the specific range required for the test. During the temperature adjustment process inside the isolation furnace 5, the test operator slides the protective cover 25 upward to expose the lower docking piece 13 and the upper docking piece 14, and then clamps the sample to be tested between the fixtures 12. After the operation is completed, the protective cover 25 is reset downward, and then the motor 10 is started. The output shaft of the motor 10 controls the rotation of the rotating wheel 9, and the rotating wheel 9 rotates 180 degrees to move the fixture 12 holding the test sample to align with the lock 8. Then the electric push rod 15 is started, and the telescopic end of the electric push rod 15 pushes the lower docking piece 13 to cooperate with the upper docking piece 14 to move the fixture 12 to engage with the lock 8 and lock it. When the device 8 is docked with the fixture 12, the locking pin 801 is controlled to retract. When the fixture 12 is in place, the locking device 8 controls the locking pin 801 to extend to fix the fixture 12 on the locking device 8. During the installation of the fixture 12 on the locking device 8, the pushing column 18 will be squeezed and the spring 19 will be compressed. After the installation of the fixture 12 is completed, the electric push rod 15 controls the docking frame 16 to disengage from the lower docking member 13. Then the loading system 2 controls the crossbeam 3 to move upward. The upward movement of the crossbeam 3 drives the tension detection component 301 to move upward. The tension detection component 301 moves upward and pulls the fixture 12 through the locking device 8 to move, so that the upper and lower fixtures 12 are separated from each other, and a tension test is performed on the sample. The test data is displayed on the display 4. When the fixtures 12 are separated from each other, the lower docking is performed. The upper and lower docking parts 13 and 14 will gradually separate. After the test is completed, the sealing door 6 can be directly opened to take out the sample. If the sample needs to be replaced for another test, the tension detection component 301 can be controlled to reset downward through the crossbeam 3 to re-dock the lower docking part 13 and the upper docking part 14. Then the telescopic end of the electric push rod 15 controls the docking frame 16 to re-dock with the lower docking part 13. Then the locker 8 controls the locking pin to unlock. Under the action of the rebound force of the spring 19, the push column 18 will be controlled to reset. The push column 18 resets to generate thrust, and the electric push rod 15 controls the docking frame 16 to gradually shrink, so that the docking frame 16 and the push column 18 cooperate with each other to gradually remove the clamp 12 from the locker 8. After the docking frame 16 is reset, the motor 10 is turned on again. The control wheel 9 rotates to move the clamp 12 to the initial position. The operator slides the protective cover 25 upward to replace the test sample. The electric push rod 15 and the docking frame 16 control the clamp 12 to load and unload. The winder 20 adapts to the loading and unloading state of the clamp 12 and controls the isolation curtain 21. During the rotation of the clamp 12, the isolation curtain 21 remains closed to keep the isolation furnace 5 sealed. When the clamp 12 completes its rotation and moves under the control of the electric push rod 15, the winder 20 controls the isolation curtain 21 to move upward so that the clamp 12 can move to the desired position. After the adjustment of the clamp 12 is completed, the winder 20 releases the control isolation curtain 21. The isolation curtain 21 resets under the action of its own weight to seal the isolation furnace 5.The isolation curtain 21 can minimize the impact on the temperature environment inside the isolation furnace 5 when the wheel 9 is working. If the internal environment of the isolation furnace 5 is at a high temperature, when the wheel 9 takes out the fixture 12 and the test sample, the protective cover 25 and the cooling fan 26 can quickly cool the fixture 12 to avoid the high temperature environment from affecting the test operator.
