Abstract

Technical Field
[0001] This utility model relates to the field of conductor tensile strength testing technology, specifically a device for testing the tensile strength of stranded copper conductors. Background Technology
[0002] After stranded copper conductors are manufactured, they undergo a series of tests before entering the sales stage to ensure that their parameters meet national standards. This requires a tensile testing device to measure the conductor's tensile strength. However, traditional tensile testing often uses horizontal pulling, which is simple but prone to causing the conductor to shift downwards from the center during long-distance cabling due to its own weight. Traditional testing methods cannot accurately simulate the actual operating environment. Therefore, those skilled in the art have provided a tensile testing device for stranded copper conductors to address the problems mentioned in the background section. Utility Model Content

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0024] Please see Figures 1-4 This utility model provides an embodiment of a stranded copper wire tensile testing device, including a base plate 2, a display screen 1 fixedly connected to the upper end of the base plate 2, a support plate 5 embedded on the upper surface of the base plate 2, a tensile testing component disposed on the support plate 5, a set of rotating grooves 10 opened on the upper surface of the base plate 2, the rotating grooves 10 being located on both sides of the support plate 5, a wire fixing component disposed in the rotating grooves 10, and the wire fixing component working in conjunction with the tensile testing component to fix the wire to the wire fixing component, and the tensile testing component can be used to test the tensile strength of the wire to further obtain the tensile data of the wire.
[0025] In this embodiment, the wire fixing assembly includes a threaded locking rod 7, a locking nut 8, a rotating block 9, a limiting block 11, a positioning block 12, a limiting groove 13, a first locking groove 14, a first locking block 15, a second locking block 16, a third locking block 17, and a second locking groove 18. A limiting block 11 is fixedly connected inside the base plate 2 and is placed within the rotating groove 10. A positioning block 12 is fixedly connected to the upper end of the limiting block 11. A rotating block 9 is rotatably connected inside the base plate 2. A limiting groove 13 is formed at the lower end of the rotating block 9. The rotating block 9 is sleeved on the surfaces of the limiting block 11 and the positioning block 12 through the limiting groove 13. A threaded locking rod 7 is fixedly connected to the upper end of the rotating block 9. A first locking block 15 is fixedly connected to the upper end of the rotating block 9. A first locking groove 14 is formed at the upper end of the first locking block 15. A second locking block 16 is sleeved on the surface of the threaded locking rod 7. A second locking groove 16 is formed at the lower end of the second locking block 16. The locking groove 18 and the second locking groove 18 are used in conjunction with the first locking groove 14. The upper end of the second locking block 16 is provided with the first locking groove 14. The surface of the threaded locking rod 7 is fitted with a third locking block 17, which is located above the second locking block 16. The lower end of the third locking block 17 is provided with the second locking groove 18. The surface of the threaded locking rod 7 is threaded with a locking nut 8. The lower end of the locking nut 8 is tightly attached to the third locking block 17. The rotating block 9 is fitted onto the surface of the limiting block 11, thereby enabling the rotating block 9 to rotate to a certain extent. At this time, when the wire is fixed between the first locking block 15 and the second locking block 16, the lateral force is eliminated, and only the longitudinal tension is retained, further preventing the wire from detaching. When the wire is placed between the first locking groove 14 and the second locking groove 18, the wire can be better fixed due to the inclined arrangement of the first locking groove 14 and the second locking groove 18.
[0026] In this embodiment, the tensile testing assembly includes a pressure sensor 3, a threaded rod 4, a fixed rod 6, a servo motor 19, a sliding groove 20, a threaded sleeve 21, and a sliding block 22. A sliding groove 20 is formed within a support plate 5, and a sliding block 22 is slidably connected within the support plate 5, with the sliding block 22 positioned within the sliding groove 20. A servo motor 19 is fixedly connected to one end of the support plate 5, and a threaded rod 4 is provided at the output end of the servo motor 19. A threaded sleeve 21 is threadedly connected to the surface of the threaded rod 4, and the threaded sleeve 21 is fixedly connected to the sliding block 22. A fixed rod 6 is fixedly connected to the upper end of the sliding block 22, and a pressure sensor 3 is fixedly connected to the surface of the fixed rod 6. The servo motor 19 drives the threaded rod 4 to rotate, which in turn, under the connection of the threaded sleeve 21, drives the sliding block 22 to adjust. During the movement of the fixed rod 6, the pressure sensor 3 contacts the wire and causes it to deflect. Tensile data is obtained based on the degree of deflection. With the cooperation of the wire fixing assembly, the data obtained near the wire fixing assembly is the longitudinal tensile data, while the data obtained near the pressure sensor 3 is the comprehensive tensile data.
[0027] The wires are placed in the wire fixing assembly, which consists of a locking rod and multiple locking blocks, and can effectively fix the position of multiple wires. After the servo motor 19 is started, the rotation of the threaded rod 4 causes the sliding block 22 to move along the sliding groove 20. As the sliding block 22 moves, the fixing rod 6 also shifts. The pressure sensor 3 contacts the wire and generates a corresponding offset. At this time, the device can apply a pulling force to the wire. During the process of the wire being subjected to the pulling force, the pressure sensor 3 measures the force on the wire in real time to measure the degree of deformation of the wire, and then outputs this force on the display screen 1.
[0028] After the conductor is fixed to the conductor fixing component, the tensile testing component can be activated to offset the center point of the conductor. As the degree of offset increases, the overall data of the conductor in longitudinal and vertical tensile strength can be simulated to ensure that it is better adapted to the fixing environment.
[0029] The use of locking grooves can better fix the beginning of the wire between the locking blocks, ensuring better stability in subsequent tensile tests. At the same time, the locking blocks can be rotated to adjust their angle during tensile tests to prevent them from coming loose.
[0030] This specification describes embodiments, but not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
