Description
Technical Field
[0001] This utility model relates to the field of iron wire strength testing technology, and in particular to iron wire elongation strength testing equipment. Background Technology
[0002] Wire elongation refers to the stretching and deformation of iron wire under stress. Strength testing equipment is needed because, from a product quality perspective, it can determine whether the iron wire meets industry standards and helps control production quality and establish a traceability system; from a safety perspective, it can identify potential safety hazards in advance, provide reliable data for engineering design to ensure structural safety and reliability; and from a technological innovation perspective, it can both guide the research and development of new materials and help companies improve production processes, increase efficiency, and reduce costs.
[0003] In existing technologies, some strength testing equipment involves placing both ends of an iron wire on the bottom of two pressure plates, then tightening the pressure plates by turning a screw. The two pressure plates are then spaced apart to stretch the iron wire. While the tensile test can reveal the strength and ductility of the iron wire under axial tension, it is difficult to verify the wire's performance under stress in different directions. This leads to inaccurate assessments of the iron wire's actual application performance, affecting product quality and safety. Therefore, to address these shortcomings, an iron wire ductility strength testing device has been proposed. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wire elongation strength testing device. This device aims to improve the existing technology, which makes it difficult to test the performance of iron wire under stress in different directions, thus leading to inaccurate evaluation of the actual application performance of iron wire and affecting product quality and safety.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire elongation strength testing device, comprising a workbench, a control block provided on the front side of the workbench, a support assembly for carrying objects fixedly connected to the bottom end of the workbench, a work plate fixedly connected to the top end of the workbench, cylinders fixedly connected to both the left and right sides of the workbench, a moving block fixedly connected to the driving end of the cylinder, limit blocks fixedly connected to both the front and rear sides of the moving block, a sliding block fixedly connected to the top end of the moving block, a support base fixedly connected to the top end of the sliding block, a motor fixedly connected to one side of the support base, a rotating plate fixedly connected to the driving end of the motor, fixed columns fixedly connected to adjacent sides of the two rotating plates, a rotating disk rotatably connected inside the support base, an arc-shaped groove formed on the outside of the rotating disk, and mounting seats fixedly connected to adjacent sides of the two arc-shaped grooves.
[0006] Furthermore, a fixing block is fixedly connected to each of the two mounting bases on their adjacent sides. An electric push rod is fixedly connected inside the fixing block. A force transmission block is fixedly connected to the drive end of the electric push rod. A connecting block is rotatably connected to the upper and lower ends of one side of the force transmission block. A connecting rod is rotatably connected to the outside of each pair of connecting blocks on their distant sides. A clamping plate is fixedly connected to the distant sides of the multiple connecting rods. Multiple friction blocks are fixedly connected to the adjacent sides of each pair of clamping plates.
[0007] Furthermore, the support assembly includes multiple support legs, the top ends of which are fixedly connected to the four corners of the bottom of the workbench, and suction cups are fixedly connected to the bottom of the support legs.
[0008] Furthermore, the external part of the movable block is slidably connected to the inside of the top end of the worktable, and two limiting holes are opened at the top end of the movable block, with the external part of the limiting block slidably connected to the inside of the limiting holes.
[0009] Furthermore, a sliding hole is provided at the top of the working plate, and the outside of the sliding block is slidably connected to the inside of the sliding hole.
[0010] Furthermore, the bottom end of the support base is slidably connected to the top end of the working plate, and the outside of the fixing column is slidably connected to the inside of the arc-shaped groove.
[0011] Furthermore, the two rotating plates are rotatably connected to the inner side of the two support seats on opposite sides, and the two mounting seats are rotatably connected to the adjacent side of the two support seats on opposite sides. A measuring plate is fixedly connected to the rear top of the working plate.
[0012] Furthermore, the interior of the distant sides of the plurality of connecting rods are respectively rotatably connected to the exterior of the adjacent sides of the two fixed blocks, and the friction blocks are made of rubber.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, not only can the iron wire be stretched, but the fixed column can also be rotated into the arc groove by starting the motor, which drives the rotating disk to rotate. Then, the two motors move in opposite directions, causing the iron wire to twist. This can simulate the different directional force conditions encountered by the iron wire in actual use, and is no longer limited to a single axial tensile force test. This makes the performance evaluation of the iron wire closer to the actual working conditions, thereby improving the accuracy of the performance evaluation of the iron wire in actual application and improving the product quality control level.
[0015] 2. In this utility model, by activating the electric push rod, the force transmission block drives the connecting block, causing the connecting rod to rotate outside the fixed block, thereby enabling the clamping plate to quickly clamp the iron wire. Furthermore, the rubber friction block increases the friction between the clamping plate and the iron wire, which helps to improve the stability of the clamping and prevents the iron wire from sliding or shifting during the test.

[0024] Reference Figures 1 to 3This utility model provides an embodiment of a wire elongation strength testing device, including a workbench 1. A control block 2 is carefully arranged on the front side of the workbench 1, which can conveniently start the entire testing process. A support component for carrying objects is firmly fixedly connected to the bottom of the workbench 1. This support component consists of multiple support legs 3, the tops of which are tightly fixedly connected to the four corners of the bottom of the workbench 1, providing stable support for the workbench 1. Suction cups 4 are carefully fixedly connected to the bottom of the support legs 3, which can firmly adhere to the ground, ensuring that the entire device is stable and does not shake during the testing process. A work plate 5 is firmly fixedly connected to the top of the workbench 1, providing a flat base for subsequent testing operations. Cylinders 6 are fixedly connected to both the left and right sides of the workbench 1. The driving end of the cylinder 6 is powerfully fixedly connected to a moving block 7, the outside of which can smoothly slide and connect to the inside of the top of the workbench 1. Limiting blocks 8 are fixedly connected to both the front and rear sides of the movable block 7. Two limiting holes 11 are carefully opened at the top of the movable block 7. The outside of the limiting block 8 can be precisely slidably connected to the inside of the limiting holes 11 to ensure the stability of the movement of the movable block 7. A sliding block 9 is also fixedly connected to the top of the movable block 7. A support base 10 is firmly fixedly connected to the top of the sliding block 9. The bottom end of the support base 10 can be smoothly slidably connected to the top of the work plate 5. A sliding hole 12 is opened at the top of the work plate 5. The outside of the sliding block 9 can be smoothly slidably connected to the inside of the sliding hole 12, which can adjust the distance between the two support bases 10 to accommodate iron wires of different lengths.
[0025] Reference Figures 3 to 5 A motor 13 is securely fixed to one side of the support base 10. A rotating plate 14 is stably fixed to the drive end of the motor 13. The distant sides of the two rotating plates 14 are flexibly rotatably connected to the inner sides of the two support bases 10. A fixing column 15 is fixedly connected to the adjacent sides of the two rotating plates 14. The outer side of the fixing column 15 can smoothly slide within the arc-shaped groove 17. A rotating disk 16 is rotatably connected inside the support base 10. The outer side of the rotating disk 16 is carefully formed with an arc-shaped groove 17. A mounting base 18 is fixedly connected to the adjacent sides of the two arc-shaped grooves 17. The distant sides of the two mounting bases 18 are rotatably connected to the adjacent sides of the two support bases 10. A fixing block 19 is fixedly connected to the adjacent sides of the two mounting bases 18.
[0026] An electric push rod 20 is securely connected inside the fixed block 19. A force transmission block 21 is forcefully connected to the drive end of the electric push rod 20. Connecting blocks 22 are rotatably connected to both ends of one side of the force transmission block 21. Connecting rods 23 are rotatably connected to the outer sides of the distant ends of every two connecting blocks 22. Multiple connecting rods 23 are rotatably connected to the outer sides of the adjacent ends of two fixed blocks 19. Clamping plates 24 are fixedly connected to the distant ends of the multiple connecting rods 23. Multiple friction blocks 25 are fixedly connected to the adjacent ends of every two clamping plates 24. The friction blocks 25 are made of rubber, increasing the friction between the clamping plates 24 and the iron wire, enabling rapid clamping of the iron wire and preventing slippage or displacement during testing. A measuring plate 26 is fixedly connected to the rear top of the working plate 5, allowing measurement of parameters such as the length change of the iron wire during stretching and twisting during testing, in order to evaluate the elongation strength of the iron wire.
[0027] Working Principle: First, the entire testing process is initiated via the control block 2 on the front side of the workbench 1. The support legs 3 at the four corners of the bottom of the workbench 1 provide support, and the suction cups 4 at the bottom of the support legs 3 firmly adhere to the ground, ensuring the equipment remains stable and does not shake during testing. Next, the cylinders 6 on the left and right sides of the workbench 1 are activated. The drive end of the cylinders 6 drives the moving block 7 to slide inside the top of the workbench 1. Simultaneously, the limiting blocks 8 on the front and rear sides of the moving block 7 slide within the limiting holes 11 at the top of the moving block 7, ensuring the stability of the moving block 7. The sliding block 9 at the top of the moving block 7 also slides within the sliding hole 12 at the top of the work plate 5, thereby driving the support seat 10 at the top of the sliding block 9 to slide on the top of the work plate 5. The distance between the two support seats 10 is adjusted to accommodate iron wires of different lengths.
[0028] Then, the iron wire is placed between the two clamping plates 24. The electric push rod 20 inside the fixing block 19 is activated, and its drive end pushes the force transmission block 21 to move. The force transmission block 21 drives the connecting block 22 to move, causing the connecting rod 23 to rotate outside the fixing block 19, thereby moving the clamping plates 24 closer to the iron wire. The friction block 25 on the clamping plate 24 contacts the iron wire. Because the friction block 25 is made of rubber, it increases the friction between the clamping plate 24 and the iron wire, achieving rapid clamping of the iron wire and preventing it from slipping or shifting during the test.
[0029] Next, the motor 13 on one side of the support base 10 is started, and the drive end of the motor 13 drives the rotating plate 14 to rotate. The fixed column 15 on the rotating plate 14 slides in the arc groove 17, thereby driving the rotating disk 16 to rotate. The two motors 13 move in opposite directions, causing the iron wire to twist, simulating the different directional force conditions encountered by the iron wire in actual use. During the test, the measuring plate 26 on the rear side of the top of the working plate 5 can measure parameters such as the length change of the iron wire during the stretching and twisting process, so as to evaluate the elongation strength of the iron wire.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
