Description

Technical Field

[0002] Tensile strength testers typically test tensile strength, breaking strength, stress at a given elongation, adhesive force, bending test, and pressure test. They are suitable for testing various physical and mechanical properties of materials such as plastic sheets, pipes, profiles, plastic films, rubber, wires and cables. They are key equipment in material development, physical property testing, teaching and research, and quality control.

[0003] Most existing tensile testing devices clamp the two ends of an object using fixtures, and then pull the object using a drive device, such as a motor or hydraulic cylinder. The tensile force is detected by measuring the applied force and the distance moved. However, during measurement, the clamping force may affect the tensile force detection, thus affecting the accuracy of the test data and easily introducing certain errors. Furthermore, the directly fixed structure of the fixture is not convenient to adjust according to the shape of the object, thus affecting the flexibility of the device's use.

[0021] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0022] like Figures 1 to 11 As shown in the embodiment of this disclosure, a tensile force testing device for mechanical measurement is proposed, comprising a base 101, a support frame 102 fixed on the base 101, a distance monitoring structure mounted on the top of the support frame 102, a hydraulic oil conveying structure installed inside the base 101, a sliding structure installed inside the support frame 102, the sliding structure corresponding to the hydraulic oil conveying structure and the distance monitoring structure, a heat dissipation structure installed inside the base 101, the heat dissipation structure corresponding to the hydraulic oil conveying structure; a pulling structure, the pulling structure corresponding to the sliding structure, the pulling structure containing a tensile force testing structure, and an adjustment structure mounted on the lower side of the pulling structure; and a placement structure, the placement structure being rotatably connected to the base 101, the placement structure being equipped with an auxiliary testing structure, and the base 101 being equipped with a positioning structure, the positioning structure corresponding to the placement structure and the hydraulic oil conveying structure.

[0023] In this embodiment, the distance monitoring structure includes an infrared distance sensor 201, which is fixed to the top of the support frame 102. The sliding structure includes a sliding frame 203 that is slidably fitted into the support frame 102. Sliding grooves 202 are provided on both sides of the support frame 102, and the sliding frame 203 corresponds to the sliding grooves 202. The infrared distance sensor 201 corresponds to the sliding frame 203. The position and sliding distance of the sliding frame 203 are detected by the infrared distance sensor 201.

[0024] Specifically, the position of the sliding frame 203 can be monitored by the infrared distance sensor 201. The applied tension and the deformation of the object can be determined by the position of the sliding frame 203. This allows the device to measure not only the tension but also the deformation of the object, thus expanding the applicability of the device. Furthermore, the detection results of the infrared distance sensor 201 can be compared with the detection results of the tension detection structure, thereby expanding the applicability of the device.

[0025] The hydraulic oil delivery structure includes: a hydraulic oil chamber 301, which is located within the base 101. A mounting frame 302 is fixed in the center of the hydraulic oil chamber 301. A cavity 303 is formed between the bottom of the mounting frame 302 and the hydraulic oil chamber 301. Multiple filter screens 304 are fixed around the periphery of the cavity 303. A hydraulic oil pump 305 is fixed inside the mounting frame 302. The mounting frame 302 has a U-shaped cross-section, and the inner side of the mounting frame 302 is connected to the outside. The oil inlet of the hydraulic oil pump 305 is connected to the cavity 303. A pushing structure is installed inside the support frame 102, and the pushing structure corresponds to the oil outlet of the hydraulic oil pump 305.

[0026] Specifically, hydraulic oil can be drawn out by the hydraulic pump 305 and sent into the telescopic rod 505 to push the sliding frame 203 to slide and generate tension. The hydraulic oil can be simply filtered by the filter screen 304, thereby preventing internal metal particles from entering the hydraulic pump 305 and damaging it due to prolonged use, thus extending the service life of the hydraulic pump 305. In addition, the U-shaped mounting bracket 302 is directly connected to the outside, which facilitates the maintenance of the hydraulic pump 305 and facilitates ventilation and heat dissipation of the hydraulic pump 305, preventing the hydraulic pump 305 from overheating and extending its service life. This ensures that the hydraulic pump 305 can work normally to draw out hydraulic oil to drive the sliding frame 203 to generate tension, thereby ensuring the effectiveness of tension detection.

[0027] The heat dissipation structure includes: a cooling chip 401, which is fixed inside a mounting bracket 302. Multiple heat dissipation plates 402 are fixed to the inner side of the mounting bracket 302. A connecting box 501 is fixed inside the hydraulic oil chamber 301. Multiple heat-conducting rods 403 are fixed between the connecting box 501 and the mounting bracket 302. Multiple first heat-conducting plates 404 are fixed to the inner side of the connecting box 501, and multiple second heat-conducting plates 405 are fixed to the outer side of the connecting box 501. The connecting box 501 is connected to the oil outlet of the hydraulic oil pump 305. The cooling chip 401 cools the hydraulic oil, while the heat-conducting rods 403, the first heat-conducting plates 404, and the second heat-conducting plates 405 assist in heat exchange with the hydraulic oil. The heat dissipation plates 402 assist in heat dissipation from the cooling chip 401.

[0028] Specifically, an external fan can be installed to blow air directly into the mounting bracket 302, cooling the inside through the cooling plate 401. The heating surface of the cooling plate 401 generates heat and transfers it to the heat sink 402. The external fan can blow air directly into the mounting bracket 302, cooling both the hydraulic oil pump 305 and the heat sink 402, thus ensuring the cooling effect of the cooling plate 401 and maintaining its stable quality. The cooling surface of the cooling plate 401 generates a lower temperature, which then exchanges heat with the hydraulic oil through the heat-conducting rod 403, the first heat-conducting plate 404, and the second heat-conducting plate 405, thereby cooling the hydraulic oil and preventing it from overheating. This ensures the hydraulic oil can provide normal pressure to push the sliding bracket 203, thus guaranteeing the stability of the detection.

[0029] The pushing structure includes a telescopic rod 505, which is fixed in a sliding groove 202. The sliding groove 202 includes a first rod body 506 and a second rod body 507. The first rod body 506 and the second rod body 507 are slidably connected. The second rod body 507 is fixedly connected to a sliding frame 203. The first rod body 506 is connected to a connecting box 501. The connecting box 501 has a connecting port 503 and an oil outlet 502. An electric valve 504 is fixed in the connecting box 501. The electric valve 504 corresponds to the connecting port 503, and the connecting port 503 is connected to the first rod body 506.

[0030] Specifically, hydraulic oil is pumped into the connecting box 501 by the hydraulic oil pump 305, and then enters the first rod 506 through the connecting port 503. At this time, the greater pressure can push the second rod 507 upward, causing the second rod 507 to drive the sliding frame 203 to slide upward. The sliding frame 203 can then be used to pull, thereby measuring the tension. After the measurement is completed, the electric valve 504 is opened, allowing the hydraulic oil to flow back into the hydraulic oil chamber 301 through the electric valve 504, thus realizing the recycling of hydraulic oil and reducing the waste of hydraulic oil. Furthermore, during the pushing process, the opening and closing of the electric valve 504 can be controlled to ensure that the hydraulic oil can provide better pressure, thereby enabling the device to perform long-term and fixed tension detection, making the device more flexible in use and expanding its application range.

[0031] The positioning structure includes: multiple positioning seats 701, each fixed to a base 101 and connected to a communicating box 501. A sliding cavity 702 is provided within each positioning seat 701, and a sliding plate 703, which has a T-shaped structure, is slidably fitted within the sliding cavity 702. A rotating shaft 706 is rotatably fitted within each positioning seat 701, and friction plates 705 and push plates 707 are fixed to both sides of the rotating shaft 706, with the push plate 707 corresponding to the sliding plate 703. Hydraulic oil pushes the sliding plate 703 upwards, and the sliding plate 703 pushes the push plate 707, causing the friction plate 705 to rotate.

[0032] Specifically, hydraulic oil can be pumped into the connecting box 501 by the hydraulic oil pump 305, and then the hydraulic oil enters the positioning seat 701, causing the hydraulic oil to push the sliding plate 703 upward. The sliding plate 703 pushes the push plate 707, thereby driving the rotating shaft 706 to rotate until the friction plate 705 contacts the rotating plate 601. This generates significant friction between the friction plate 705 and the rotating plate 601, which fixes the position of the rotating plate 601, thus ensuring the stability of the object during measurement, improving the accuracy of the test results, and preventing errors caused by object shaking.

[0033] The placement structure includes: a rotating plate 601, which is rotatably connected to the base 101; a friction plate 705 in contact with the rotating plate 601; and an auxiliary detection structure mounted on the rotating plate 601. The rotating plate 601 is positioned by the friction generated by the rotation of the friction plate 705. The auxiliary detection includes: a clamping seat 602, which is fixed to the rotating plate 601. A screw 603 is threaded into the clamping seat 602, and a lower pressure plate 604 is rotatably fitted to the end of the screw 603. A first pressure sensor 605 is fixed on the lower pressure plate 604, and the lower pressure plate 604 is slidably connected to the clamping seat 602. Rotating the screw 603 causes the lower pressure plate 604 to slide downwards, pressing and fixing the object to be detected.

[0034] Specifically, an object, such as a steel bar structure, can be placed on the rotating plate 601, with both ends of the steel bar passing through the clamping seats 602. Then, the screw 603 is manually rotated, causing the screw 603 to drive the lower pressure plate 604 to slide downwards, thereby squeezing and fixing the steel bar. This ensures the stability of the ends of the steel bar during tensile measurement, thus guaranteeing the accuracy of the measurement results. Furthermore, during measurement, the downward pressure can be measured by the first pressure sensor 605. When pulling, the data from the first pressure sensor 605 changes, which can be compared with the change in tensile force. This prevents the clamping force from affecting the tensile force measurement of the device, ensuring the accuracy of the test results.

[0035] The pulling structure includes: a mounting base 801, which corresponds to the sliding frame 203; a screw 802 is fixed on the mounting base 801; a first nut 803 is installed at the end of the screw 802; the screw 802 passes through the sliding frame 203 and is connected to the first nut 803; a support rod 804 is fixed inside the mounting base 801; a tension detection structure includes a second pressure sensor 806 fixed on the support rod 804; a pulling frame 805 is installed inside the mounting base 801, which corresponds to the support rod 804; and an adjustment structure includes: a pull rod 807, which includes a third rod body 808 and a fourth rod body 809, which are slidably connected; a second nut 810 is rotatably fitted at the bottom of the third rod body 808; the second nut 810 is threadedly fitted to the fourth rod body 809; and a pull rope 811 is fixed at the end of the fourth rod body 809.

[0036] Specifically, the pull rope 811 is tied to the periphery of the object or directly bound to the object. The pull rope 811 can be a steel wire rope. When the sliding frame 203 slides upward, the sliding frame 203 can pull the mounting base 801, thereby driving the pull rod 807 to pull upward, thus pulling the object upward for tension detection. At this time, the magnitude of the tension is detected by the second pressure sensor 806 to ensure the accuracy of the detection results. When the object is tall, such as a C-shaped object, the second nut 810 can be manually turned to adjust the position of the fourth rod 809 upward, thereby ensuring that the pull rope 811 can be properly fixed to the object, thus ensuring that objects of different shapes and sizes can be detected, making the device more flexible to use and expanding the scope of application of the device.

[0037] Workflow: Place the steel bar structure on the rotating plate 601, with both ends of the steel bar passing through the clamping seats 602. Then, manually rotate the screw 603, causing the screw 603 to drive the lower pressure plate 604 to slide downwards, thereby squeezing and fixing the steel bar. Tie the pull rope 811 around the object or directly tie it to the object. Then, start the hydraulic oil pump 305, which sends hydraulic oil into the connecting box 501. The hydraulic oil then enters the first rod 506 through the connecting port 503. At this time, the greater pressure can push the second rod 507 upwards, causing the second rod 507 to slide. The frame 203 slides upwards, allowing for pulling. Simultaneously, hydraulic oil enters the positioning seat 701, pushing the sliding plate 703 upwards. The sliding plate 703 then pushes the push plate 707, causing the rotating shaft 706 to rotate until the friction plate 705 contacts the rotating plate 601. This generates significant friction between the friction plate 705 and the rotating plate 601, fixing the position of the rotating plate 601. At this point, the second pressure sensor 806 detects the pulling force, and the first pressure sensor 605 measures the downward pressure. When the object is pulled, the data from the first pressure sensor 605 changes. The position of the sliding frame 203 can be monitored by the infrared distance sensor 201. The applied tension and the deformation of the object can be determined by the position of the sliding frame 203. After the measurement is completed, the electric valve 504 is opened, allowing the hydraulic oil to flow back into the hydraulic oil chamber 301, thus realizing the recycling of the hydraulic oil. During the measurement, an external fan can be installed to blow air directly into the mounting bracket 302, which is cooled by the cooling plate 401. At this time, the heating surface of the cooling plate 401 generates heat and dissipates the heat. The heat is transferred to the heat sink 402, and the external fan can blow air directly into the mounting bracket 302. This not only cools the hydraulic oil pump 305 but also the heat sink 402, thus ensuring the cooling effect of the cooling chip 401 and its stable quality. At this time, the cooling surface of the cooling chip 401 can generate a lower temperature, which then exchanges heat with the hydraulic oil through the heat-conducting rod 403, the first heat-conducting plate 404, and the second heat-conducting plate 405, thereby cooling the hydraulic oil and preventing it from overheating, thus ensuring the accuracy of the measurement results.
