Description

Technical Field

[0001] This utility model relates to the field of tensile strength testing equipment, specifically a tensile strength testing device for high-toughness steel wire. Background Technology

[0002] Steel wire is widely used in critical applications such as lifting and traction where high strength and reliability are required. In actual operation, it faces extremely harsh working conditions. It not only has to withstand huge tensile loads, but also suffers from frequent friction and wear. Long-term repeated stress can easily lead to fatigue failure, resulting in local wire breakage. It may also be accompanied by deformation problems. All these conditions will significantly reduce the original tensile strength of the steel wire and greatly affect its safety performance.

[0003] To ensure the reliability of steel wire during repeated use and to avoid safety accidents caused by insufficient strength, in accordance with the strict provisions of relevant national standards, the steel wire must undergo comprehensive and accurate tensile testing. Existing steel wire tensile strength testing devices usually require the steel wire to be wrapped around the surface of a fixing block multiple times during the testing process, and then the end of the steel wire is fixed with a fixing device.

[0004] The fixing method of this steel wire tensile strength testing equipment is quite cumbersome, which leads to a lot of time spent by the staff in fixing the steel wire, increasing the workload of the staff and resulting in low working efficiency of the testing equipment. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a tensile strength testing device for high-toughness steel wire, so as to solve the technical problem that the method of fixing steel wire in the tensile strength testing device is relatively cumbersome.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tensile strength testing device for high-toughness steel wire, comprising a testing device, a testing groove being formed at the top of the testing device, a first detector being fixed at the end of the testing groove, a second detector being movably installed inside the testing groove, a fixing ring being fixed inside the first detector, a compression ring being installed at the top of the fixing ring, a limit post being provided at the end of the compression ring, a lead screw being connected to the top of the compression ring, a connecting block being fixed to the outer wall of the compression ring, a compression block being connected to the end of the connecting block, a fixing post being fixed to the bottom of the compression block, a fixing hole being formed inside the first detector, and a steel wire being installed inside the fixing hole.

[0007] By adopting the above technical solution, the technical problem of the cumbersome method of fixing the steel wire in the steel wire tensile strength testing equipment is solved. The steel wire is inserted into the interior of the first detector through the fixing hole. The screw drives the extrusion ring to move in the vertical direction through the rotating block, so that the extrusion ring fixes the end of the steel wire through the extrusion and cooperation with the fixing ring. During the up and down movement of the extrusion ring, the extrusion ring drives the extrusion block to move in the vertical direction through the connecting block. The extrusion block extrudes and fixes the steel wire located inside the fixing hole through the fixing column.

[0008] The present invention is further configured such that the internal structure of the second detector is the same as that of the first detector, a driving block is fixed at the bottom of the second detector, and a moving groove is provided inside the detection device.

[0009] By adopting the above technical solution, the moving slot limits the movement of the second detector through the driving block, thereby reducing the positional deviation of the second detector during movement.

[0010] The present invention is further configured such that a hydraulic cylinder is installed at one end of the detection device, a hydraulic rod is connected to the end of the hydraulic cylinder, and a drive block is connected to the end of the hydraulic rod.

[0011] By adopting the above technical solution, the hydraulic cylinder pulls the drive block horizontally in the moving groove through the hydraulic rod, providing tension for the second detector to detect the tensile strength of the steel wire.

[0012] The present invention is further configured such that a handle is connected to one end of the lead screw, and a rotating block is fixed to the end of the lead screw.

[0013] By adopting the above technical solution, the handle is manually rotated, which drives the lead screw to rotate. The lead screw drives the extrusion ring to move in the vertical direction through the rotating block.

[0014] The present invention is further configured such that a control button is provided on one side of the detection device, a display screen is installed on the outer wall of the detection device, and a groove is provided on one side of the detection device.

[0015] By adopting the above technical solution, the testing device displays the test results of the steel wire tensile strength on the screen, and the groove on one side of the testing device facilitates the installation and fixing of the steel wire by the staff.

[0016] The present invention is further configured such that a limiting groove is provided inside the first detector, and multiple sets of limiting blocks are fixed to the outer wall of the extrusion block.

[0017] By adopting the above technical solution, when the extrusion block moves inside the first detector, the limiting groove inside the first detector limits the movement of the extrusion block through the limiting block, ensuring that the extrusion block can move in the vertical direction.

[0018] The present invention is further configured such that a first protrusion is provided on the outer wall of the fixing column, and a second protrusion is installed on the inner wall of the fixing hole.

[0019] By adopting the above technical solution, since the diameters at both ends of the fixing hole are larger than the diameter in the middle, the steel wire will bend slightly when the fixing post squeezes the steel wire. Furthermore, the first protrusion on the outer wall of the fixing post cooperates with the second protrusion on the inner wall of the fixing hole to squeeze and fix the wire, thereby reducing the slippage of the steel wire located inside the fixing hole.

[0020] The present invention is further configured such that a washer is installed at the end of the inner wall of the extrusion ring, and a third protrusion is provided on the inner wall of the extrusion ring and the fixing ring.

[0021] By adopting the above technical solution, the extrusion ring and the fixing ring are squeezed together by the third protrusion on the inner wall to fix the end of the steel wire, and the washer has a certain elasticity. The washer elastically fixes the outer wall of the steel wire, increasing the fixing contact area of ​​the extrusion ring on the steel wire.

[0022] In summary, the present invention has the following main advantages:

[0023] This invention solves the technical problem of the cumbersome method of fixing steel wire in steel wire tensile strength testing equipment by setting up a detection device, a first detector, a compression block, a fixing hole, a compression ring, and a fixing ring. The steel wire is inserted into the first detector through the fixing hole, and the screw drives the compression ring to move vertically through the rotating block. The compression ring fixes the end of the steel wire by compression with the fixing ring. During the up and down movement of the compression ring, the compression ring drives the compression block to move vertically together through the connecting block. The compression block compresses and fixes the steel wire located inside the fixing hole through the fixing post.

[0024] This utility model, by setting a fixing post, a fixing hole, a first protrusion and a second protrusion, ensures that the diameter of the two ends of the fixing hole is larger than the diameter of the middle part, so that the steel wire will be slightly bent when the fixing post squeezes the steel wire. Furthermore, the first protrusion on the outer wall of the fixing post cooperates with the second protrusion on the inner wall of the fixing hole to squeeze and fix the steel wire, thereby reducing the slippage of the steel wire located inside the fixing hole.

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] A tensile strength testing device for high-toughness steel wire, such as Figure 1 - Figure 5As shown, the device includes a detection device 1. A detection groove 2 is formed on the top of the detection device 1. A first detector 3 is fixed to the end of the detection groove 2. A second detector 8 is movably installed inside the detection groove 2. A fixing ring 601 is fixed inside the first detector 3. A compression ring 6 is installed on the top of the fixing ring 601. A limit post 605 is provided at the end of the compression ring 6. A lead screw 602 is connected to the top of the compression ring 6. A connecting block 403 is fixed to the outer wall of the compression ring 6. A compression block 4 is connected to the end of the connecting block 403. A fixing post 404 is fixed to the bottom of the compression block 4. A fixing hole 406 is formed inside the first detector 3. A steel wire 7 is installed inside the hole 406, which solves the technical problem of the cumbersome method of fixing the steel wire in the steel wire tensile strength testing equipment. The steel wire 7 is inserted into the first detector 3 through the fixing hole 406. The screw 602 drives the extrusion ring 6 to move in the vertical direction through the rotating block 604, so that the extrusion ring 6 fixes the end of the steel wire 7 through the extrusion engagement with the fixing ring 601. During the up and down movement of the extrusion ring 6, the extrusion ring 6 drives the extrusion block 4 to move in the vertical direction together through the connecting block 403. The extrusion block 4 extrudes and fixes the steel wire 7 located inside the fixing hole 406 through the fixing post 404.

[0034] Please see Figure 1 and Figure 2 The internal structure of the second detector 8 is the same as that of the first detector 3. A drive block 502 is fixed at the bottom of the second detector 8. A moving groove 503 is provided inside the detection device 1. The moving groove 503 limits the movement of the second detector 8 through the drive block 502, thereby reducing the positional deviation of the second detector 8 during the movement.

[0035] Please see Figure 2 A hydraulic cylinder 5 is installed at one end of the detection device 1. A hydraulic rod 501 is connected to the end of the hydraulic cylinder 5. A drive block 502 is connected to the end of the hydraulic rod 501. The hydraulic cylinder 5 pulls the drive block 502 horizontally in the moving groove 503 through the hydraulic rod 501, so as to provide tension for the second detector 8 to detect the tensile strength of the steel wire 7.

[0036] Please see Figure 3 One end of the lead screw 602 is connected to a handle 603, and a rotating block 604 is fixed to the end of the lead screw 602. When the handle 603 is rotated manually, the handle 603 drives the lead screw 602 to rotate, and the lead screw 602 drives the extrusion ring 6 to move in the vertical direction through the rotating block 604.

[0037] Please see Figure 1The detection device 1 has a control button 101 on one side, a display screen 102 installed on the outer wall of the detection device 1, and a groove 103 on one side of the detection device 1. The detection device 1 displays the test results of the tensile strength of the steel wire 7 on the display screen 102, and the groove 103 on one side of the detection device 1 facilitates the installation and fixing of the steel wire 7 by the staff.

[0038] Please see Figure 3 The first detector 3 has a limiting groove 402 inside, and the outer wall of the extrusion block 4 is fixed with multiple sets of limiting blocks 401. When the extrusion block 4 moves inside the first detector 3, the limiting groove 402 inside the first detector 3 limits the movement of the extrusion block 4 through the limiting blocks 401, so as to ensure that the extrusion block 4 can move in the vertical direction.

[0039] Please see Figure 4 The outer wall of the fixing post 404 is provided with a first protrusion 405, and the inner wall of the fixing hole 406 is provided with a second protrusion 407. Since the diameters at both ends of the fixing hole 406 are larger than the diameter in the middle, the steel wire 7 will be slightly bent when the fixing post 404 squeezes the steel wire 7. Furthermore, the first protrusion 405 on the outer wall of the fixing post 404 cooperates with the second protrusion 407 on the inner wall of the fixing hole 406 to squeeze and fix the steel wire 7, thereby reducing the slippage of the steel wire 7 located inside the fixing hole 406.

[0040] Please see Figure 3 A washer 606 is installed at the end of the inner wall of the extrusion ring 6. A third protrusion 607 is provided on the inner wall of the extrusion ring 6 and the fixing ring 601. The extrusion ring 6 and the fixing ring 601 are squeezed together by the third protrusion 607 on the inner wall to fix the end of the steel wire 7. The washer 606 has a certain elasticity and elastically fixes the outer wall of the steel wire 7, increasing the contact area between the extrusion ring 6 and the steel wire 7.

[0041] The working principle of this utility model is as follows: First, the steel wire 7 is inserted into the first detector 3 through the fixing hole 406, and the end of the steel wire 7 is inserted into the end of the fixing ring 601. Then, the handle 603 is manually rotated, and the handle 603 drives the lead screw 602 to rotate. The lead screw 602 drives the extrusion ring 6 to move vertically through the rotating block 604, so that the extrusion ring 6 fixes the end of the steel wire 7 through the extrusion fit with the fixing ring 601. During the up and down movement of the extrusion ring 6, the extrusion ring 6 drives the extrusion block 4 to move vertically together through the connecting block 403. The extrusion block 4 fixes the end of the steel wire 7 through the fixing post 404. The steel wire 7 located inside the fixing hole 406 is compressed. Since the diameter at both ends of the fixing hole 406 is larger than the diameter in the middle, the steel wire 7 will be slightly bent when the fixing post 404 compresses it, thereby reducing the slippage of the steel wire 7 located in the fixing hole 406. Then, the other end of the steel wire 7 is fixed inside the second detector 8 using the same operation. Subsequently, the hydraulic cylinder 5 is operated by controlling the control button 101. The hydraulic cylinder 5 pulls the drive block 502 to move horizontally in the moving groove 503 through the hydraulic rod 501. The detection device 1 displays the detection result of the tensile strength of the steel wire 7 on the display screen 102.
