Description

Technical Field

[0001] This utility model relates to the field of materials testing technology, and in particular to a device for testing the tensile strength of copper alloy stranded wire. Background Technology

[0002] Copper alloy stranded wire, as an important conductive material, plays a vital role in various fields such as power transmission, communications, and aerospace. It is formed by stranding multiple fine copper alloy wires together in a specific manner to create a conductive core with high flexibility and strength. This stranded wire not only improves conductivity but also enhances its resistance to external mechanical stress. Therefore, tensile strength testing is a crucial step in ensuring the quality and performance of copper alloy stranded wire during production. However, existing copper alloy stranded wire tensile strength testing equipment has gradually revealed significant limitations in clamping, positioning, and actual testing processes.

[0003] Specifically, existing testing equipment can only clamp and position the stranded wire at a single point on the end, resulting in poor clamping capability. This poses a risk of the stranded wire falling off during testing. This unstable clamping method not only reduces the reliability of test results but also increases operational complexity and makes it difficult to meet the requirements of high-precision and high-standard quality inspection.

[0004] Therefore, to address the shortcomings of existing technologies, we urgently need a testing device for the tensile strength of copper alloy stranded wires. This testing device would not only effectively prevent the stranded wire from detaching during testing, improving the accuracy and reliability of test data, but also enhance the ease of operation and durability of the equipment, thereby significantly improving work efficiency and product quality. Utility Model Content

[0005] The purpose of this invention is to provide a copper alloy stranded wire extension tensile testing device, which solves the problem that existing testing devices can only clamp and position the stranded wire at a single point on the end, resulting in poor clamping ability and the risk of the stranded wire falling off during the test.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for testing the tensile strength of copper alloy stranded wire includes a support base and two upright plates disposed on top of the support base.

[0008] A movable block is provided on one side of the top of the support base. The movable block is movably connected to the top of the support base through a horizontal pushing structure. A pressure sensor is connected inside the movable block.

[0009] One side of the upright plate is fixedly connected to the top of the support base, and the other side of the upright plate is connected to the pressure sensor inside the moving block;

[0010] Each of the upright plates has a vertical plate on one side, and a number of clamping plates are provided between the vertical plate and the upright plate. Each clamping plate is rotatably connected to one side of an adjusting screw with one end threaded through the vertical plate.

[0011] Preferably, a horizontal plate is provided at the bottom of the vertical plate, one end of which is fixedly connected to the vertical plate, and the other end is fixedly connected to the side wall of the vertical plate with bolts.

[0012] Preferably, the top of the support base is provided with a movable groove, and both sides of the bottom are fixedly connected with support frames.

[0013] Preferably, a rubber pad is fixedly connected to one side of the clamping plate, and a plurality of anti-slip grooves are provided on one side of the rubber pad.

[0014] Preferably, the horizontal pushing structure includes a sliding block that is slidably connected to the inside of the moving groove and a lead screw that is rotatably connected to the inside of the moving groove, wherein the sliding block and the lead screw are in sliding engagement.

[0015] Preferably, a drive motor is installed at one end of the support base, and the output shaft of the drive motor is connected to the end of the lead screw.

[0016] This utility model has at least the following beneficial effects:

[0017] By incorporating multiple clamping plates and adjusting screws, the copper alloy stranded wire is securely clamped at multiple points, significantly enhancing clamping stability and reliability. This effectively prevents the wire from detaching during testing and improves the accuracy and reliability of test data. Secondly, the design of the moving block and horizontal pushing structure allows for flexible adjustment of the wire's stress state, enabling tensile testing to be conducted under different conditions and adapting to diverse testing needs.

In addition, the overall ease of operation of the device is improved, reducing operational complexity caused by the equipment's complexity and making the testing process more efficient and safer.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Example 1

[0027] Please see Figure 1-5 As shown, a copper alloy stranded wire extension tensile testing device according to this embodiment includes a support base 1 and two upright plates 2 disposed on the top of the support base 1;

[0028] A movable block 3 is provided on one side of the top of the support base 1. The movable block 3 is movably connected to the top of the support base 1 through a horizontal pushing structure. A pressure sensor is connected inside the movable block 3.

[0029] One side of the upright plate 2 is fixedly connected to the top of the support base 1, and the other side of the upright plate 2 is connected to the pressure sensor inside the moving block 3.

[0030] Each upright plate 2 has a vertical plate 7 on one side, and several clamping plates 9 are arranged between the vertical plate 7 and the upright plate 2. Each clamping plate 9 has an adjusting screw 6 with one end threaded through the vertical plate 7 rotatably connected to one side.

[0031] First, the two ends of the copper alloy stranded wire to be tested are placed on clamping plates 9 between two upright plates 2. Each clamping plate 9 is adjusted by an adjusting screw 6 with one end threaded through the upright plate 7, ensuring that the stranded wire is firmly clamped at multiple points, avoiding the instability and risk of detachment caused by traditional single-point clamping. One upright plate 2 is fixedly connected to the top of the support base 1, while the other upright plate 2 is connected to a pressure sensor inside the moving block 3. The moving block 3 is movably connected to the top of the support base 1 through a horizontal pushing structure, allowing it to move along the surface of the support base 1 to accommodate copper alloy stranded wires of different lengths. When the test begins, the clamping force at both ends of the stranded wire is further strengthened by adjusting the screw 6, and the horizontal pushing structure is activated to gradually move the moving block 3 away from the fixed upright plate 2, thereby applying a uniform tension to the copper alloy stranded wire. Throughout the process, the pressure sensor monitors and records the force applied to the stranded wire in real time until the predetermined maximum tension is reached or the stranded wire breaks.

[0032] Example 2

[0033] Please see Figure 1-5 As shown in this embodiment, a copper alloy stranded wire extension tensile testing device has a horizontal plate 8 at the bottom of a vertical plate 7. One end of the horizontal plate 8 is fixedly connected to the vertical plate 7, and the other end is fixedly connected to the side wall of the vertical plate 2 with bolts. Specifically, the design of having a horizontal plate 8 at the bottom of the vertical plate 7, with one end fixedly connected to the vertical plate 7 and the other end fixedly connected to the side wall of the vertical plate 2 with bolts, enhances the stability of the entire clamping system. During the operation, when clamping and testing the copper alloy stranded wire, the horizontal plate 8 provides additional support, ensuring the structural strength between the vertical plate 7 and the vertical plate 2, preventing deformation or damage to the equipment due to excessive force, and achieving the effect of enhancing the overall structural stability.

[0034] A rubber pad is fixedly connected to one side of the clamping plate 9. Several anti-slip grooves 10 are formed on one side of the rubber pad. Specifically, the design of the rubber pad fixedly connected to one side of the clamping plate 9 and having several anti-slip grooves 10 increases the friction between the clamping plate 9 and the copper alloy stranded wire. During the working process, when the position of the clamping plate 9 is adjusted using the adjusting screw 6, the rubber pad and its anti-slip grooves 10 can better grip the surface of the stranded wire, preventing it from sliding or falling off during testing, thus improving clamping stability and testing accuracy.

[0035] Example 3

[0036] Please see Figure 1-5As shown in this embodiment, a copper alloy stranded wire extension tensile testing device has a movable groove 11 on the top of the support base 1, and support frames 4 are fixedly connected to both sides of the bottom. Specifically, the design of the movable groove 11 on the top of the support base 1 and the support frames 4 fixedly connected to both sides of the bottom improves the stability and load-bearing capacity of the support base 1. During the operation, the movable block 3 slides in the movable groove 11 through a horizontal pushing structure, and the support frames 4 provide a solid support foundation for the entire device, ensuring that there will be no shaking or tilting during the application of tensile force, thus improving the stability and reliability of the equipment.

[0037] The horizontal pushing structure includes a sliding block 12 slidably connected to the inside of the moving groove 11 and a lead screw 13 rotatably connected to the inside of the moving groove 11. The sliding block 12 and the lead screw 13 are in sliding engagement. Specifically, through the design of the horizontal pushing structure including the sliding block 12 slidably connected to the inside of the moving groove 11 and the lead screw 13 rotatably connected to the inside of the moving groove 11, the sliding block 12 and the lead screw 13 are in sliding engagement, thus achieving precise control of the moving block 3. In the working process, the drive motor 5 drives the lead screw 13 to rotate through the output shaft, causing the sliding block 12 to translate along the moving groove 11, thereby driving the moving block 3 to move. This design not only improves the accuracy of operation but also simplifies the operation steps, achieving the effect of improving operational convenience and testing efficiency.

[0038] A drive motor 5 is mounted on one end of the support base 1. The output shaft of the drive motor 5 is connected to the end of the lead screw 13. Specifically, this design, with the drive motor 5 mounted on one end of the support base 1 and its output shaft connected to the end of the lead screw 13, further enhances the precise control of the displacement of the moving block 3. During operation, the operator starts the drive motor 5, whose output shaft drives the lead screw 13 to rotate, causing the sliding block 12 to move smoothly along the moving groove 11. This achieves the process of applying uniform tension to the copper alloy stranded wire. This automated design not only improves the accuracy of the test but also reduces human error, thereby improving the reliability of test data and work efficiency. These improvements work together to significantly enhance the overall performance and reliability of the copper alloy stranded wire tensile strength testing device.

[0039] This solution includes the following workflow:

[0040] First, the two ends of the copper alloy stranded wire to be tested are placed on the clamping plates 9 between the two vertical plates 2. Each clamping plate 9 is adjusted by an adjusting screw 6 with one end threaded through the vertical plate 7 to ensure that the stranded wire is firmly clamped at multiple points. A rubber pad is fixedly connected to one side of the clamping plate 9, and several anti-slip grooves 10 are opened on one side of the rubber pad. When the adjusting screw 6 adjusts the position of the clamping plate 9, the rubber pad and its anti-slip grooves 10 can better grip the surface of the stranded wire and prevent it from sliding or falling off during the test. A horizontal plate 8 is set at the bottom of the vertical plate 7. One end of the horizontal plate 8 is fixedly connected to the vertical plate 7, and the other end is fixedly connected to the side wall of the vertical plate 2 with bolts. When clamping and tensile testing the copper alloy stranded wire, the horizontal plate 8 provides additional support, ensuring the structural strength between the vertical plate 7 and the vertical plate 2 and preventing the equipment from deforming or being damaged due to excessive force. One side of the vertical plate 2 is fixedly connected to the top of the support base 1, while the other side of the vertical plate 2 is connected to the pressure sensor inside the moving block 3. The movable block 3 is movably connected to the top of the support base 1 via a horizontal pushing structure, allowing it to slide along the surface of the support base 1 to accommodate copper alloy stranded wires of different lengths. The top of the support base 1 has a moving groove 11, and support frames 4 are fixedly connected to both sides of the bottom. The movable block 3 slides within the moving groove 11 via a sliding block 12 in the horizontal pushing structure, ensuring no swaying or tilting occurs during the application of tension. A drive motor 5 is installed at one end of the support base 1. The output shaft of the drive motor 5 is connected to the end of the lead screw 13. When the operator starts the drive motor 5, its output shaft rotates the lead screw 13, causing the sliding block 12 to move smoothly along the moving groove 11, thus gradually moving the movable block 3 away from the fixed upright plate 2 and applying a uniform tension to the copper alloy stranded wire. Throughout the process, a pressure sensor monitors and records the force applied to the stranded wire in real time until the predetermined maximum tension is reached or the stranded wire breaks.

[0041] The beneficial effects of this design are as follows: First, by setting multiple clamping plates 9 and adjusting screws 6, stable clamping of copper alloy stranded wire at multiple points is achieved. The rubber pads and anti-slip grooves 10 on the clamping plates 9 further enhance friction, avoiding the instability and risk of falling off caused by traditional single-point clamping, and improving clamping stability and testing accuracy. Second, the design of the horizontal plate 8 at the bottom of the vertical plate 7 enhances the stability of the entire clamping system, ensuring the structural strength between the vertical plate 7 and the upright plate 2, preventing equipment deformation or damage due to excessive force, and improving the overall structural stability. Third, the moving groove 11 at the top of the bearing base 1 and the support frame 4 at the bottom work together to improve the bearing base 1. The stability and load-bearing capacity ensure that there will be no shaking or tilting during the application of tensile force, enhancing the reliability and safety of the equipment. Furthermore, the cooperative design of the sliding block 12 and the lead screw 13 in the horizontal pushing structure enables precise control of the moving block 3. The drive motor 5 drives the lead screw 13 to rotate through the output shaft, causing the sliding block 12 to move smoothly along the moving groove 11. This not only improves operational accuracy but also simplifies the operation steps, reduces human error, and enhances testing efficiency and data reliability. Finally, the application of a pressure sensor can monitor and record the force applied to the stranded wire in real time, providing accurate data support for the test results and further improving the scientific rigor and reliability of the test. These improvements work together to solve the problems of unstable clamping and positioning, complex operation, and insufficient testing accuracy in existing technologies, significantly improving the overall performance and reliability of the copper alloy stranded wire extension tensile testing device, and providing strong technical support for the quality inspection and performance evaluation of copper alloy stranded wires.
