[0002] As the name implies, a copper-clad steel single wire is a wire with a copper layer wrapped around a steel wire. It utilizes the skin effect of low-voltage high-frequency signals. In the high-frequency region, the signal mainly travels along the surface. Therefore, as long as the thickness of the copper layer reaches a certain range, the signal in a certain frequency band can be ensured to be transmitted.

[0003] In order to ensure the quality control and quality inspection of copper-clad steel single wires, they are mostly evaluated through tensile tests. At present, although traditional testing institutions can meet the basic testing requirements, in the actual use process, the clamping mechanism of traditional testing institutions is relatively weak, the clamping is uneven, and due to the special material of copper-clad steel, it is easy to slip or break at the fixture during the process of clamping the specimen. Therefore, a tensile test structure for copper-clad steel single wires is urgently needed. Summary of the Utility Model

Detailed Embodiment

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Refer to Figures 1-5 , the copper-clad steel single-wire tensile test structure includes a tensile testing machine body 1. A clamping table 5 is installed in the middle of the tensile testing machine body 1 through a fixed table 4. Bottom chutes 11 and side chutes 12 are respectively opened at the bottom and side of the clamping table 5 for limiting the clamping cylinder one 7 and the clamping cylinder two 8. A locking block 9 is arranged on one side away from the clamping cylinder two 8. One side of the locking block 9 is connected to a screw 13. One end of the screw 13 is connected to an adjusting disk 6 through a connecting cylinder 61;

[0024] Further, rubber rings 15 are installed on the upper and lower ends of the inner walls of the clamping cylinder one 7 and the clamping cylinder two 8, and limiting blocks 81 are installed on one side of the clamping cylinder one 7 and the clamping cylinder two 8 for limiting and sliding installation in the side chute 12.

[0025] Further, the tensile testing machine body 1 is installed with a test fixture 3 through a lifting table 2. Among them, the test fixture 3 and the clamping mechanism arranged in the clamping table 5 are the same mechanism, both for the purpose of clamping wire materials.

[0026] Further, a connecting cylinder 61 is fixedly installed on one side of the clamping table 5. A screw 13 is installed in the middle of the connecting cylinder 61 by screw connection. One end of the screw 13 is fixedly installed with an adjusting disk 6, and the other end is fixedly installed with a rotating connection head 131. The rotating connection head 13 is embedded and installed on one side of the inner wall of the clamping table 5.

[0027] Further, one end of the rotating connection head 13 is rotatably installed at one end of the locking block 9, and the bottom end of the locking block 9 is limited and slidably installed in the bottom chute 11.

[0028] Further, a wedge-shaped clamping block 10 is installed in the middle of the locking block 9. The wedge-shaped clamping block 10 protrudes from the upper and lower walls of the locking block 9. During the test, the wedge-shaped clamping block 10 squeezes and contacts the outer wall of the wire material, and the wedge-shaped setting can effectively avoid the situation of wire material sliding.

[0029] Further, an extension block 71 is arranged on one side of the bottom of the clamping cylinder one 7. One end of the extension block 71 is embedded in the notch opened at one end of the bottom chute 11, and a spring 14 is installed in the notch. The spring 14 is connected to the extension block 71.

[0030] Further, the upper and lower ends of one side of the clamping cylinder two 8 protrude outward and fit with the locking block 9.

[0031] In this embodiment, the copper-clad steel single-wire to be detected is inserted between the clamping cylinder 7 and the clamping cylinder 8 arranged inside the clamping table 5. The clamping cylinder 7 is adaptively telescoped through the spring 14 under the extrusion of the wire. At the same time, the clamping cylinder 7 and the clamping cylinder 8 are closed and the outer wall of the wire is pre-clamped. At the same time, by rotating the adjusting disk 6, the screw 13 rotates and the locking block 9 is displaced through screw rotation. The locking block 9 moves towards the clamping cylinder 7 under the rotation of the adjusting disk 6. At the same time, the locking block 9 pushes the clamping cylinder 8 on one side to move in the bottom sliding groove 11. And as the clamping cylinder 7 and the clamping cylinder 8 are gradually clamped, the outer wall of the wire is squeezed and locked by the rubber ring 15 arranged inside the cylinder wall. At the same time, due to the setting of the wedge-shaped clamping block 10, the wedge-shaped clamping block 10 extends into the inner sides of the clamping cylinder 7 and the clamping cylinder 8 under the pushing action and squeezes the outer wall of the wire, thus completing the locking operation.

[0032] At the same time, the top end of the wire is connected to the test fixture 3 arranged on the lifting table 2, and the tensile testing machine body 1 is controlled to perform the test operation.

[0033] Among them, in the actual use process, the wedge-shaped piece of the wedge-shaped clamping block 10 inclines downward, and can effectively lock and limit the outer wall of the wire during the stretching process.

[0034] Among them, in the actual use process, wedge-shaped clamping blocks 10 are also arranged on the inner wall of the clamping table 5 on the side of the clamping cylinder 7 to clamp the wire.

[0035] Among them, in the actual use process, the settings of the bottom sliding groove 11 and the side sliding groove 12 can effectively improve the moving stability of the clamping cylinder 7 and the clamping cylinder 8, and ensure the clamping efficiency.

[0036] In the present utility model, by rotating the adjusting disk 6, the locking block 9 and the wedge-shaped clamping block 10 are driven to move inwards, and the clamping cylinder 8 is pushed to move towards the clamping cylinder 7 to clamp the wire placed inside. At the same time, with the cooperation of the rubber ring 15 and the wedge-shaped clamping block 10, the wire can be effectively clamped. And due to the wedge-shaped setting, the loosening of the wire can be effectively avoided. And through the rubber ring 15, the clamping stability and uniformity of the wire can be improved, effectively avoiding the situations of falling off and breaking during the clamping process of the traditional test mechanism, and further improving the test accuracy.

[0037] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
