Description

Technical Field

[0001] The utility model relates to the technical field of tensile strength detection, in particular to a tensile strength detection device for the production of new stainless steel wires. Background Technique

[0002] Steel wires are mainly used in occasions such as lifting and traction, and the working conditions are relatively harsh. During use, frictional wear, fatigue failure, local wire breakage and deformation will occur, reducing the tensile strength of the steel wires. To ensure the reliability of repeated use of the steel wires, tensile tests need to be carried out in accordance with relevant national standards.

[0003] A patent with the publication number of CN219284872U discloses a tensile strength detection device for the production of stainless steel wires. In this patent, by rotating the knob, the rotating rod is synchronously driven to rotate. The rotating rod synchronously drives the second bevel gear to rotate, the second bevel gear synchronously drives the bevel gear to rotate, and the bevel gear synchronously drives the threaded rod. At the same time, since the cavity restricts the movement trajectory of the lifting plate, when the threaded rod rotates, the lifting plate will be synchronously driven to move up and down. The movement of the lifting plate synchronously drives the fixed plate to move up and down, and the movement of the fixed plate bends and fixes the stainless steel wire in the through hole. When it is necessary to move the fixed block for testing, by rotating the operating disk, the bidirectional threaded rod is synchronously driven to rotate. At the same time, since the connecting plate is restricted by the sliding groove in its movement trajectory, and the connecting plate is respectively fixedly connected to the fixed block and the threaded sleeve, when the bidirectional threaded rod rotates, the threaded sleeve, the connecting plate and the fixed block will be synchronously driven to move horizontally. Through the above structure, it can enable the staff to fix the stainless steel wire more easily. By bending the steel wire to increase the contact area and fix it at the same time, it avoids the process that the staff needs to wind the steel wire multiple times and tie knots. While improving the overall work efficiency, it also synchronously reduces the work intensity of the staff.

[0004] The above device still has some problems in actual use. By passing the stainless steel wire through the through hole, then pressing and fixing the stainless steel wire in the inner cavity of the through hole through the fixing structure, and then driving the fixed block to pull the stainless steel wire for tensile strength testing. However, when installing a thicker steel wire, due to the limitation of the size of the through hole, the steel wire cannot be quickly inserted into the inner cavity of the through hole and pressed and fixed. Moreover, if the diameter of the steel wire exceeds the diameter of the through hole, the steel wire cannot be inserted into the inner cavity of the through hole for fixing, resulting in the problem that the tensile strength of the steel wire cannot be quickly detected.

[0005] Based on this, the utility model designs a tensile strength detection device for the production of new stainless steel wires to solve the above-mentioned problems. Content of the Utility Model

[0009] And the steel wire clamping and fastening assembly includes a cross-shaped sliding groove opened inside the U-shaped sliding frame, a fixed sliding column is fixedly connected to the inner cavity of the cross-shaped sliding groove, two clamping blocks are symmetrically slidably connected to the outer part of the fixed sliding column, and a steel wire fastening groove is arranged between the two clamping blocks, and fastening teeth are uniformly arranged in the inner cavity of the steel wire fastening groove.

[0010] Preferably, a bidirectional screw rod is rotatably connected to the inner cavity of the cross-shaped sliding groove, the bidirectional screw rod is threadedly connected to the two clamping blocks, and a crank is fixedly connected to one end of the bidirectional screw rod passing through the U-shaped sliding frame.

[0011] Preferably, worm wheels are fixedly connected to the outer parts of the first bidirectional screw rods, the worm wheels are meshed with a worm, a rotating column is fixedly connected to the inside of the worm, and the rotating column is installed on the upper wall of the inner cavity of the workbench.

[0012] Preferably, two mounting brackets are symmetrically installed on the upper wall of the inner cavity of the workbench, a servo motor is installed between the two mounting brackets, a driving bevel gear is fixedly connected to the output shaft end of the servo motor, the driving bevel gear is meshed with a driven bevel gear, and the inside of the driven bevel gear is fixedly connected to the rotating column.

[0013] Preferably, a pressure application and detection assembly is arranged in the middle of the upper end of the workbench, and the pressure application and detection assembly includes a sliding groove opened in the middle of the upper end of the workbench, a second bidirectional screw rod is rotatably connected to the inner cavity of the sliding groove, a driving motor is arranged on the inner wall of the sliding groove, and the output shaft end of the driving motor is fixedly connected to the second bidirectional screw rod.

[0014] Preferably, two sliders are threadedly connected to the outer part of the second bidirectional screw rod, and push rods are rotatably connected to both ends of the two sliders. One end of the push rod is rotatably connected to a pulley, and the pulley slides and supports in the inner cavity of the sliding groove. One end of the push rod is rotatably connected to a U-shaped fixing block, a supporting block is fixedly connected to the upper end of the U-shaped fixing block, and a pressure sensor is arranged inside the upper end of the supporting block.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. In the present utility model, the steel wire is installed between two clamping blocks. Meanwhile, the steel wire clamping and fastening assembly is driven to clamp and limit the steel wire. Then, the fastening tooth block is used to bite the steel wire to increase the friction between the clamping block and the steel wire, preventing the steel wire from detaching from the clamping block when pulling the steel wire for tensile strength testing. Then, by driving the first bidirectional threaded rod to rotate, the U-shaped sliding frames are driven to move away from each other through threaded transmission, and then the two ends of the steel wire are pulled, so as to perform tensile strength testing on the steel wire. Thus, it solves the problem that when the tensile strength testing equipment for the production of new stainless steel wires installs a relatively thick steel wire, due to the limitation of the size of the through hole, the steel wire cannot be quickly inserted into the inner cavity of the through hole and pressed and fixed. Moreover, if the diameter of the steel wire exceeds the diameter of the through hole, the steel wire cannot be inserted into the inner cavity of the through hole for fixing, resulting in the inability to quickly perform tensile strength testing on the steel wire.

[0017] 2. In the present utility model, when performing tensile strength testing on a relatively thick steel wire, the steel wire is pulled straight by two U-shaped sliding frames. Then, the driving pressure application and testing assembly's support block slides out of the chute and moves upward to apply pressure to the steel wire. During the process of the support block applying pressure to the steel wire, the pressure sensor is used to real-time detect the pressure applied to the steel wire, and then it is displayed through the console, so as to facilitate observing the tensile strength data of the steel wire, avoiding that when performing tensile strength testing on a relatively thick steel wire, it is difficult to apply a large pressure to perform tensile strength testing on the steel wire by using the U-shaped sliding frame to pull the steel wire for testing. Thus, it solves the problem that when the existing tensile strength testing equipment for the production of new stainless steel wires performs tensile strength testing on a relatively thick steel wire, since the operator manually rotates the crank to drive the bidirectional threaded rod to operate, the support frame will be subject to a large pulling resistance, and it is difficult for the operator to drive it to move away from each other through the bidirectional threaded rod, resulting in the inability to accurately perform tensile strength testing on the steel wire.

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] To facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the relevant accompanying drawings. Several embodiments of the present invention are given in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0029] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0030] A tensile strength detection device for the production of new stainless steel wires, including a workbench 1, one end of the upper end surface of the workbench 1 is provided with a control console 2, four grooves 4 are symmetrically opened on the upper end surface of the workbench 1, and two grooves 4 are in a group and communicate with each other. A first bidirectional threaded rod 18 is rotatably connected to the inner cavity of each group of grooves 4, and two U-shaped sliding frames 5 are threadedly connected to the outside of the first bidirectional threaded rod 18, and a wire clamping and fastening assembly is arranged inside the two U-shaped sliding frames 5;

[0031] And the wire clamping and fastening assembly includes a cross chute 7 opened inside the U-shaped sliding frame 5, a fixed sliding column 8 is fixedly connected to the inner cavity of the cross chute 7, two clamping blocks 9 are symmetrically slidably connected to the outside of the fixed sliding column 8, and a wire fastening groove is arranged between the two clamping blocks 9, and fastening tooth blocks are uniformly arranged in the inner cavity of the wire fastening groove.

[0032] Specifically, in the prior art, a stainless steel wire is passed through a through hole, and then the stainless steel wire in the inner cavity of the through hole is pressed and fixed by a fixing structure. Subsequently, the stainless steel wire is pulled by driving a fixing block to perform a tensile strength test. However, when installing a thicker steel wire, due to the limitation of the size of the through hole, the steel wire cannot be quickly inserted into the inner cavity of the through hole and pressed and fixed. Moreover, if the diameter of the steel wire exceeds the diameter of the through hole, the steel wire cannot be inserted into the inner cavity of the through hole for fixing, resulting in the problem that the tensile strength of the steel wire cannot be quickly detected;

[0033] In the present invention, the steel wire is installed between two clamping blocks 9. At the same time, the two clamping blocks 9 are driven to slide and move closer to each other outside the fixed sliding column 8. A steel wire fastening groove is provided between the two clamping blocks 9, and fastening teeth are uniformly arranged in the inner cavity of the steel wire fastening groove. Therefore, the steel wire can be clamped and limited by the steel wire fastening groove, and at the same time, the steel wire is bitten by the fastening teeth to increase the friction between the clamping block 9 and the steel wire, preventing the steel wire from detaching from the clamping block 9 when pulling the steel wire for tensile strength detection. Then, by driving the first bidirectional threaded rod 18 to rotate and making the first bidirectional threaded rod 18 threadedly drive the U-shaped sliding frame 5 to move away from each other, the clamping block 9 drives the two ends of the steel wire to be pulled, thereby performing a tensile strength test on the steel wire. During the tensile strength test of the steel wire, the console 2 is used to display the tensile force of the clamping block 9 pulling the steel wire, and the weight that the steel wire can withstand is calculated and displayed, thus solving the problem that in the tensile strength detection device for the production of new stainless steel wires, the stainless steel wire is passed through the through hole, and then the stainless steel wire in the inner cavity of the through hole is pressed and fixed by a fixing structure. Subsequently, the stainless steel wire is pulled by driving a fixing block to perform a tensile strength test. However, when installing a thicker steel wire, due to the limitation of the size of the through hole, the steel wire cannot be quickly inserted into the inner cavity of the through hole and pressed and fixed. Moreover, if the diameter of the steel wire exceeds the diameter of the through hole, the steel wire cannot be inserted into the inner cavity of the through hole for fixing, resulting in the problem that the tensile strength of the steel wire cannot be quickly detected.

[0034] As Figure 1 、 Figure 2 and Figure 4 shown, a bidirectional lead screw 10 is rotatably connected to the inner cavity of the cross-shaped sliding groove 7. The bidirectional lead screw 10 is threadedly connected to the two clamping blocks 9, and one end of the bidirectional lead screw 10 penetrates through the U-shaped sliding frame 5 and is fixedly connected to a crank 6.

[0035] As Figure 2 and Figure 3 shown, worm wheels 17 are fixedly connected to the outside of the first bidirectional threaded rod 18. The worm wheels 17 are meshed with a worm 16. A rotating column 15 is fixedly connected to the inside of the worm 16. The rotating column 15 is installed on the upper wall of the inner cavity of the workbench 1.

[0036] As Figure 2And Figure 3 As shown in the figure, two mounting brackets 11 are symmetrically installed on the upper wall of the inner cavity of the workbench 1, and a servo motor 12 is installed between the two mounting brackets 11. A transmission bevel gear 13 is fixedly connected to the output shaft end of the servo motor 12. The transmission bevel gear 13 is meshed and connected with a driven bevel gear 14, and the inner part of the driven bevel gear 14 is fixedly connected with a rotating column 15.

[0037] Specifically, when detecting the tensile strength of the steel wire, the servo motor 12 is started to drive the transmission bevel gear 13 to rotate, and the transmission bevel gear 13 meshes and drives the driven bevel gear 14 to rotate. At the same time, the driven bevel gear 14 drives the rotating column 15 to rotate, and then drives the two worm gears 16 to rotate. During the rotation of the worm gears 16, the worm gears 17 will be driven to rotate, and at the same time, the first double-threaded rod 18 will be driven to rotate, and then the two U-shaped sliding frames 5 are driven to move away from each other by screw transmission. At the same time, the two U-shaped sliding frames 5 are used to pull the steel wire to move synchronously, so as to detect the tensile strength of the steel wire. Thus, it solves the problem that when the existing tensile strength detection equipment for the production of new stainless steel wires detects the tensile strength of thicker steel wires, since the operator manually rotates the crank to drive the double-threaded rod to operate, the support frame will be subjected to a large pulling resistance, and it is difficult for the operator to drive it to move away from each other through the double-threaded rod, resulting in the inability to accurately detect the tensile strength of the steel wire.

[0038] As Figure 1 And Figure 5 As shown in the figure, a pressure application and detection component 3 is arranged in the middle of the upper end of the workbench 1. The pressure application and detection component 3 includes a chute 31 opened in the middle of the upper end of the workbench 1. A second double-threaded rod 32 is rotatably connected in the inner cavity of the chute 31. A drive motor 36 is arranged on the inner wall of the chute 31, and the output shaft end of the drive motor 36 is fixedly connected with the second double-threaded rod 32.

[0039] As Figure 3 And Figure 5 As shown in the figure, two sliders 33 are threadedly connected to the outside of the second double-threaded rod 32. Both ends of the two sliders 33 are rotatably connected with a push rod 34. One end of the push rod 34 is rotatably connected with a pulley 37, and the pulley 37 slides and supports in the inner cavity of the chute 31. One end of the push rod 34 is rotatably connected with a U-shaped fixing block 38. A support block 35 is fixedly connected to the upper end of the U-shaped fixing block 38, and a pressure sensor is arranged inside the upper end of the support block 35.

[0040] Specifically, in the prior art, a crank is usually used to rotate a bidirectional threaded rod, and the bidirectional threaded rod is threadedly driven to move two support frames to drive the clamping mechanisms to move away from each other. At the same time, a steel wire is installed on the support frames, and the clamping mechanisms are used to clamp and fix the steel wire. Then, the two support frames are used to pull the steel wire to achieve the tensile strength detection of the steel wire. However, when detecting the tensile strength of a relatively thick steel wire, since the operator manually rotates the crank to drive the bidirectional threaded rod to operate, the support frames will be subject to a large pulling resistance, and it is difficult for the operator to drive them to move away from each other through the bidirectional threaded rod, resulting in the problem that the tensile strength of the steel wire cannot be accurately detected.

[0041] When the present invention detects the tensile strength of a relatively thick steel wire, the steel wire is pulled straight by two U-shaped sliding frames 5. Then, the driving motor 36 is started to drive the second bidirectional threaded rod 32 to rotate. At the same time, the second bidirectional threaded rod 32 is threadedly driven to move two sliders 33 closer to each other. Then, the two sliders 33 drive the push rods 34 to move closer to each other. At the same time, the push rods 34 use the pulleys 37 to slide in the inner cavity of the chute 31 to ensure stability. Then, the push rods 34 push the U-shaped fixing block 38 to move, and the U-shaped fixing block 38 drives the supporting block 35 to slide out of the chute 31 and move upward. Furthermore, the supporting block 35 moves upward to fit with the steel wire. Then, the push rod 34 is driven to push the supporting block 35 to apply pressure to the steel wire. During the process of the supporting block 35 applying pressure to the steel wire, the pressure sensor is used to detect the pressure applied to the steel wire in real time, and then it is displayed through the console 2, so as to facilitate observing the tensile strength data of the steel wire. This avoids the problem that when detecting the tensile strength of a relatively thick steel wire, it is difficult to apply a large pressure to detect the tensile strength of the steel wire by using the U-shaped sliding frame 5 to pull the steel wire. Thus, it solves the problem that in the prior art, when the tensile strength detection device for the production of new stainless steel wires detects the tensile strength of a relatively thick steel wire, since the operator manually rotates the crank to drive the bidirectional threaded rod to operate, the support frames will be subject to a large pulling resistance, and it is difficult for the operator to drive them to move away from each other through the bidirectional threaded rod, resulting in the problem that the tensile strength of the steel wire cannot be accurately detected.

[0042] Working principle of the utility model: By installing the steel wire between two clamping blocks 9, and simultaneously driving the two clamping blocks 9 to slide and move closer to each other outside the fixed sliding column 8. There is a steel wire fastening groove between the two clamping blocks 9, and fastening teeth are evenly arranged in the inner cavity of the steel wire fastening groove. Thus, the steel wire can be clamped and limited by the steel wire fastening groove, and at the same time, the fastening teeth are used to bite the steel wire to increase the friction between the clamping block 9 and the steel wire, preventing the steel wire from detaching from the clamping block 9 when pulling the steel wire for tensile strength testing. Then, by driving the first bidirectional threaded rod 18 to rotate, and making the first bidirectional threaded rod 18 thread-drive the U-shaped sliding frame 5 to move away from each other, thus driving the two ends of the steel wire by the clamping block 9 to be pulled, so as to conduct tensile strength testing on the steel wire. During the tensile strength testing of the steel wire, the console 2 is used to display the tensile force of the clamping block 9 pulling the steel wire, and the weight that the steel wire can withstand is calculated and displayed;

[0043] When conducting tensile strength testing on a thicker steel wire, the steel wire is pulled straight by the two U-shaped sliding frames 5, and then the driving motor 36 is started to drive the second bidirectional threaded rod 32 to rotate. At the same time, the second bidirectional threaded rod 32 thread-drives the two sliders 33 to move closer to each other. Then, the two sliders 33 drive the push rods 34 to move closer to each other. At the same time, the push rods 34 use the pulleys 37 to slide stably in the inner cavity of the chute 31. Then, the push rods 34 push the U-shaped fixing block 38 to move, and the U-shaped fixing block 38 drives the supporting block 35 to slide out of the chute 31 and move upward. Thus, the supporting block 35 moves upward to fit with the steel wire. Then, by driving the push rods 34 to push the supporting block 35 to apply pressure to the steel wire. During the process of the supporting block 35 applying pressure to the steel wire, the pressure sensor is used to detect the pressure applied to the steel wire in real time, and then it is displayed through the console 2, so as to facilitate observing the tensile strength data of the steel wire and avoid that when conducting tensile strength testing on a thicker steel wire, it is difficult to apply a large pressure to the steel wire for tensile strength testing by using the U-shaped sliding frame 5 to pull the steel wire for testing.
