Description

Technical Field

[0001] This utility model belongs to the field of material deformation testing technology, and specifically relates to a material deformation testing device. Background Technology

[0002] With the continuous development of materials science, the research on material properties is becoming increasingly in-depth. The deformation behavior of materials under different environments and external forces is one of the key indicators for evaluating their performance. Developing accurate material deformation testing equipment helps to gain a deeper understanding of the mechanical and physical properties of materials, providing important support for the research and development and application of new materials. In industrial production, the degree of material deformation directly affects the quality and reliability of products. For example, in fields such as metal processing, automobile manufacturing, and aerospace, it is necessary to conduct strict deformation tests on materials to ensure that parts meet design requirements, improve product quality, reduce production costs, and reduce safety hazards.

[0003] Existing material deformation testing devices mostly use fixed loads to test the deformation of materials, and the test range is fixed. This cannot meet the deformation testing requirements of different materials under different load conditions, thus affecting the accuracy of material deformation testing. Therefore, we propose a material deformation testing device. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a material deformation testing device, comprising:

[0006] Fixed base plate;

[0007] A height adjustment mechanism is provided on one side of the upper end of the fixed base plate;

[0008] A load force adjustment mechanism is provided on the height adjustment mechanism and moves up and down with the height adjustment mechanism to adjust the height.

[0009] A clamping and fixing mechanism is disposed on the fixed base plate on the side away from the height adjustment mechanism, and the clamping and fixing mechanism is used to clamp and fix the test material connected to the load force adjustment mechanism;

[0010] A displacement-type deformation analysis mechanism is disposed on the fixed base plate below the material to be tested, and the displacement-type deformation analysis mechanism is used to analyze the deformation data of the material to be tested.

[0011] Preferably, the height adjustment mechanism includes a lifting chamber housing, a rotating handle wheel, a bearing seat, a threaded rod, a threaded seat, and a guide lifting block;

[0012] The lifting chamber is disposed on one side of the upper end of the fixed base plate. The threaded rod is rotatably disposed in the lifting chamber through the threaded seat. The upper end of the threaded rod passes through the lifting chamber and is connected to the rotating handle wheel through the bearing seat.

[0013] The guide lifting block is connected to the threaded seat and extends outward to connect with the load force adjustment mechanism.

[0014] Preferably, the load force adjustment mechanism includes a mounting base, a high-frequency telescopic cylinder, a fixed end, and a pressure deformation roller;

[0015] The mounting base is connected to the guide lifting block, the high-frequency telescopic cylinder is mounted on the mounting base, the fixed end is mounted on the output end of the high-frequency telescopic cylinder, and the pressure deformation roller is mounted on the fixed end.

[0016] Preferably, the fixed end has a U-shaped structure, and the pressure deformation roller is disposed on the inner side of the U-shape of the fixed end.

[0017] Preferably, the clamping and fixing mechanism includes a fixing vertical plate, a clamping seat, and a threaded pressure block;

[0018] The fixed vertical plate is disposed on the side of the fixed base plate away from the lifting cavity shell, the clamping seat is disposed on the side of the fixed vertical plate facing the lifting cavity shell, and the threaded pressure block is threadedly connected to the clamping seat.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This utility model includes a height adjustment mechanism, a load force adjustment mechanism, a clamping and fixing mechanism, and a displacement-type deformation analysis mechanism. In use, the handle wheel is manually rotated, which drives the threaded rod to rotate, causing the threaded seat and guide lifting block to move on the lifting chamber shell. This raises the load force adjustment mechanism to the same horizontal level as the clamping and fixing mechanism. Then, the high-frequency telescopic cylinder extends, pushing the fixed end and the pressure deformation roller towards the clamping and fixing mechanism. One end of the material to be tested is then fixed to the pressure deformation roller, and the other end is placed in the clamping seat. The threaded pressure block is then rotated downwards to press down on the material, which is now in a naturally straightened state. Finally, the height of the load force adjustment mechanism on the height adjustment mechanism is manually adjusted, and the high-frequency telescopic cylinder is activated. Rapid contraction causes a high-frequency telescopic cylinder to elongate the test material through a fixed end and a pressure deformation roller, resulting in upward or downward free deformation of the material. The material then contacts the pressure deformation roller, applying pressure to induce upward or downward bending deformation. A displacement slider moves along a displacement guide rail, moving an infrared deformability analyzer. The analyzer measures the deformation of the test material using infrared technology and analyzes the deformation data. Different loads can be applied to the test material using height and load adjustment mechanisms, allowing for the analysis of deformation data under different load conditions. This meets the deformation testing requirements of different materials under various load states, improving the accuracy of material deformation testing. Attached Figure Description

The height adjustment mechanism 2 includes a lifting chamber shell 201, a rotating handle wheel 202, a bearing seat 203, a threaded rod 204, a threaded seat 205, and a guide lifting block 206. The lifting chamber shell 201 is located on one side of the upper end of the fixed base plate 1. The threaded rod 204 is rotatably mounted in the lifting chamber shell 201 through the threaded seat 205. The upper end of the threaded rod 204 passes through the lifting chamber shell 201 and is connected to the rotating handle wheel 202 through the bearing seat 203. The guide lifting block 206 is connected to the threaded seat 205 and extends outward to connect with the load force adjustment mechanism 3.

[0034] The load force adjustment mechanism 3 is mounted on the height adjustment mechanism 2 and moves up and down with the height adjustment mechanism 2 to adjust the height. The load force adjustment mechanism 3 includes a mounting base 301, a high-frequency telescopic cylinder 302, a fixed end 303, and a pressure deformation roller 304. The mounting base 301 is connected to the guide lifting block 206. The high-frequency telescopic cylinder 302 is mounted on the mounting base 301. The fixed end 303 is located at the output end of the high-frequency telescopic cylinder 302. The pressure deformation roller 304 is located on the fixed end 303. The fixed end 303 has a U-shaped structure, and the pressure deformation roller 304 is located on the inner side of the U-shape of the fixed end 303.

[0035] The clamping and fixing mechanism 4 is located on the fixed base plate 1 on the side away from the height adjustment mechanism 2. The clamping and fixing mechanism 4 is used to clamp and fix the test material 5 connected to the load force adjustment mechanism 3. The clamping and fixing mechanism 4 includes a fixed vertical plate 401, a clamping seat 402, and a threaded pressure block 403. The fixed vertical plate 401 is located on the fixed base plate 1 on the side away from the lifting chamber shell 201. The clamping seat 402 is located on the side of the fixed vertical plate 401 facing the lifting chamber shell 201. The threaded pressure block 403 is threadedly connected to the clamping seat 402. The clamping seat 402 has a U-shaped structure. One end of the test material 5 is located on the pressure deformation roller 304, and the other end of the test material 5 is located inside the clamping seat 402 and is pressed and fixed by the threaded pressure block 403.

[0036] The displacement deformation analysis mechanism 6 is set on the fixed base plate 1 below the material 5 to be tested. The displacement deformation analysis mechanism 6 is used to analyze the deformation data of the material 5 to be tested. The displacement deformation analysis mechanism 6 includes a displacement guide rail 601, a displacement slider 602 and an infrared deformation analyzer 603. The displacement guide rail 601 is set on the fixed base plate 1 below the material 5 to be tested. The displacement slider 602 is slidably engaged with the displacement guide rail 601. The infrared deformation analyzer 603 is set on the displacement slider 602.

[0037] This utility model is equipped with a height adjustment mechanism 2, a load force adjustment mechanism 3, a clamping and fixing mechanism 4, and a displacement-type deformation analysis mechanism 6. In use, the rotating handle wheel 202 is manually turned, which drives the threaded rod 204 to rotate, causing the threaded seat 205 and the guide lifting block 206 to move on the lifting cavity shell 201, so that the load force adjustment mechanism 3 is raised and lowered to the same level as the clamping and fixing mechanism 4. Then, the high-frequency telescopic cylinder 302 extends and outputs, pushing the fixed end 303 and the pressure deformation roller 304 to move towards the clamping and fixing mechanism 4. Then, one end of the material to be tested 5 is fixed on the pressure deformation roller 304, and the other end of the material to be tested 5 is placed in the clamping seat 402. The threaded pressure block 403 is rotated downwards to press the material to be tested 5. At this time, the material to be tested 5 is in a naturally straight state.

[0038] Then, manually adjust the height of the load force adjustment mechanism 3 on the height adjustment mechanism 2, and activate the high-frequency telescopic cylinder 302 for rapid retraction. This causes the high-frequency telescopic cylinder 302 to stretch the test material 5 through the fixed end 303 and the pressure deformation roller 304, causing the test material 5 to undergo upward or downward free deformation. The test material 5 then contacts the pressure deformation roller 304, applying pressure and causing it to undergo upward or downward bending deformation. This deformation is then caused by the displacement slider 602 moving on the displacement guide rail 601, which in turn moves the infrared deformation analyzer 603. The infrared deformation analyzer 603 then... The deformation of the material to be tested 5 is measured by infrared testing, and the deformation data of the material to be tested 5 is analyzed (the infrared deformation analyzer 603 is an existing technology for measuring and analyzing the deformation of the material to be tested 5, which is a well-known technical means in the art and will not be described in detail here). Different loads can be applied to the material to be tested 5 by the height adjustment mechanism 2 and the load force adjustment mechanism 3, thereby testing and analyzing the deformation data of the material to be tested 5 under different load conditions, meeting the deformation testing needs of different materials under different load conditions, and improving the accuracy of material deformation testing;

[0039] This invention can be used in the fields of machinery manufacturing, automobile, and rail and aerospace industries for quality control of parts production and product performance testing. It can also be used for testing building materials to ensure the safety and durability of building structures; for example, for testing the deformation of materials such as stainless steel, alloy steel, alloy aluminum, polytetrafluoroethylene, and Teflon.

[0040] In summary, the method of using the material deformation testing device provided in this embodiment is as follows: Manually rotate the rotating handle wheel 202, which drives the threaded rod 204 to rotate, causing the threaded seat 205 and the guide lifting block 206 to move on the lifting chamber shell 201, so that the load force adjustment mechanism 3 is raised to the same horizontal height as the clamping and fixing mechanism 4. Then, the high-frequency telescopic cylinder 302 extends and outputs, pushing the fixed end 303 and the pressure deformation roller 304 to move towards the clamping and fixing mechanism 4. Then, one end of the material to be tested 5 is fixed on the pressure deformation roller 304, and the other end of the material to be tested 5 is placed in the clamping seat 402. The threaded pressure block 403 is rotated downwards to press the material to be tested 5. At this time, the material to be tested 5 is in a naturally straight state.

[0041] Then, manually adjust the height of the load force adjustment mechanism 3 on the height adjustment mechanism 2, and start the high-frequency telescopic cylinder 302 to quickly retract it. This causes the high-frequency telescopic cylinder 302 to stretch the test material 5 through the fixed end 303 and the pressure deformation roller 304, causing the test material 5 to undergo upward or downward free deformation. The test material 5 then contacts the pressure deformation roller 304 to apply pressure, causing the test material 5 to undergo upward or downward bending deformation. The displacement slider 602 moves on the displacement guide rail 601, driving the infrared deformability analyzer 603 to move. The infrared deformability analyzer 603 performs infrared testing on the deformation of the test material 5 and analyzes the deformation data of the test material 5. Different load forces can be applied to the test material 5 through the height adjustment mechanism 2 and the load force adjustment mechanism 3, thereby testing and analyzing the deformation data of the test material 5 under different load conditions, meeting the deformation testing requirements of different materials under different load conditions.
