Description

Technical Field

[0001] The invention relates to the field of galvanized wire testing, and in particular to a finished galvanized wire tensile strength detection device and a control method thereof. Background Art

[0002] Galvanized wire is made of high-quality low-carbon steel wire rod. It is made of high-quality low-carbon steel through drawing, pickling and rust removal, high-temperature annealing, hot-dip galvanizing, cooling and other process processes. Galvanized wire is divided into hot-dip galvanized wire and cold-dip galvanized wire.

[0003] In current technical practice, after the production of galvanized wire, it is an essential step to test its strength to verify whether it meets the specified performance standards. However, in the process of using testing equipment to evaluate the strength of galvanized wire, some samples may suddenly break when subjected to high tension due to substandard quality or other factors. If the galvanized wire breaks under high tension, it may instantly release high-speed flying fragments, which may easily pose a safety threat to surrounding operators and also damage the integrity of laboratory equipment. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a finished galvanized wire tensile strength detection device and a control method thereof.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a finished galvanized wire tensile strength testing device, comprising a mobile frame, and further comprising:

[0006] Two frames, the two frames are fixedly mounted on the top of the mobile frame;

[0007] A first clamp, disposed between the two frames;

[0008] A second clamp is disposed between the two frames, and the second clamp is located below the first clamp;

[0009] A protection component is detachably installed between the two frames, and the protection component includes two movable and combined shielding members. After the two shielding members are close to each other and combined and assembled, the two shielding members form a shielding space. If the galvanized wire is suddenly broken during the test of the first clamp and the second clamp, the shielding space is used to shield the fragments of the galvanized wire when it breaks;

[0010] Among them, if a sudden break occurs during the test, the shielding space formed by the shielding piece will block and intercept the flying fragments, thereby helping to reduce the potential threat posed by the flying fragments to operators and surrounding equipment. The design of the shielding piece is not only to immediately prevent the spread of fragments, but more importantly, it helps to ensure that even at the moment of galvanized wire breaking, the scattered fragments and galvanized wire will not easily escape from the constraints of the shielding space, thereby helping to improve the overall safety of the test environment.

[0011] Preferably, the shielding member comprises:

[0012] A fixing frame, detachably fixed on the side wall of the frame;

[0013] An electric push rod is fixedly mounted on a side of the fixing bracket away from the frame;

[0014] A shielding box is fixedly mounted on the telescopic end of the electric push rod, and the upper and lower sides of the shielding box are provided with a slot having a diameter greater than the diameter of the galvanized wire;

[0015] Two semi-conical cylinders are respectively fixedly installed inside the shielding box and are respectively communicated with the two card slots.

[0016] Preferably, two sets of bias rubbing components are arranged inside the two shielding boxes, and the bias rubbing components include:

[0017] Two first electric push cylinders, the fixing parts of the two first electric push cylinders are respectively fixedly connected to the inner walls of the two shielding boxes;

[0018] Two elastic telescopic rods are respectively fixedly connected to the outer walls of the telescopic ends of the two first electric push cylinders;

[0019] Two slide rails are fixedly connected to two elastic telescopic rods respectively;

[0020] Two eccentric rubbing blocks are respectively fixedly connected to the slide rails at corresponding positions, and the eccentric rubbing blocks are provided with a flat surface and an inclined surface;

[0021] Monitoring components, used to obtain vibration information and pressure information;

[0022] When the monitoring component obtains vibration information or pressure information, the two first electric push cylinders are controlled to drive the two eccentric rubbing blocks to approach each other, so as to complete the eccentric rubbing limiting of the galvanized wire.

[0023] Preferably: the monitoring component comprises:

[0024] A plurality of vibration sensors are fixedly mounted on the inner wall of the semi-conical cylinder;

[0025] A plurality of pressure sensors are fixedly mounted on the inner wall of the semi-conical cylinder;

[0026] Wherein, the vibration sensor and the pressure sensor are cross-distributed on the inner wall of the semi-conical cylinder.

[0027] Preferably: also include:

[0028] Two second electric push cylinders, the fixing parts of the two second electric push cylinders are respectively fixedly connected to the inside of the shielding box;

[0029] Two push blocks, respectively fixedly connected to the telescopic ends of the two second electric push cylinders;

[0030] Two slide plates are respectively slidably connected to the sides of the two eccentric rubbing blocks close to each other;

[0031] Two inclined grooves are respectively provided on the two slide plates;

[0032] Two slide bars are respectively fixedly connected to the two push blocks, and the two slide bars are slidably connected to the inside of the inclined groove.

[0033] Preferably, the two push blocks on the left are provided with grooves, the interior of the grooves is provided with card slots, and the two push blocks on the right are fixedly connected with pointed blocks.

[0034] Preferably: also include:

[0035] Two sliding rods are symmetrically slidably connected to the groove;

[0036] An extrusion piece, fixedly connected to the ends of the two sliding rods close to each other;

[0037] Two springs are respectively fixedly connected between the extrusion pieces at corresponding positions and the grooves, and the springs are sleeved on the outer wall of the sliding rod;

[0038] The restoring force exerted by the extrusion helps ensure that they are tightly attached to and press the outer surface of the galvanized wire. This continuous contact and pressure application is essentially a reshaping process for the galvanized wire. Through repeated and uniform extrusion, it helps promote the formation of shape memory of the galvanized wire, ensuring that it can maintain the established bending shape after the tip block is withdrawn.

[0039] In a second aspect, the present invention provides a control method for a finished galvanized wire tensile strength detection device, the control method comprising the following steps:

[0040] Obtaining first parameter information;

[0041] Generate first control information according to the parameter information, the first control information is used to control the first electric push cylinder to start pushing out;

[0042] The first control information is sent to the first electric push cylinder to control the first electric push cylinder to push the eccentric rubbing block to move.

[0043] Preferably: the first parameter information includes vibration information and pressure information and vibration information or pressure information.

[0044] Preferably: also include:

[0045] When the first control information is generated, the second control information is also generated;

[0046] The second control information is sent to the second electric push cylinder to control the second electric push cylinder to start pushing out.

[0047] Compared with the prior art, the present invention has the following beneficial effects:

[0048] 1. The present invention provides a protective component. If a sudden break occurs during the test, the shielding space formed by the shielding member will shield and intercept the flying fragments, thereby helping to reduce the potential threat posed by the flying fragments to operators and peripheral equipment. The shielding member is designed not only to immediately prevent the spread of fragments, but more importantly, it helps to ensure that even at the moment of galvanized wire breakage, the scattered fragments and galvanized wire will not easily escape from the constraints of the shielding space, thereby helping to improve the overall safety of the test environment.

[0049] 2. Through the setting of the slide plate of the present invention, the slide plate will move downward under the guidance of the inclined groove, and the slide plate will drive the eccentric rubbing block to compress the elastic telescopic rod and move downward. The downward movement of the eccentric rubbing block will drive the clamped and limited galvanized wire to move downward, thereby helping to further avoid the probability of the galvanized wire flying out by pulling the galvanized wire downward for a certain distance.

[0050] 3. The present invention continuously applies restoring force to the extrusion parts through the setting of the extrusion parts through the spring, ensuring that they are tightly attached to and press the outer surface of the galvanized wire. This continuous contact and pressure application is essentially a process of reshaping the galvanized wire. Through repeated and uniform extrusion, it helps to promote the formation of shape memory of the galvanized wire, ensuring that it can still maintain a predetermined bending shape after the tip block withdraws, and after the tip block withdraws from the inside of the groove, the extrusion part that loses support will bend the galvanized wire again, and then through multiple bending, the galvanized wire can stably maintain the desired geometric shape and will not easily return to its original state.

DETAILED DESCRIPTION

[0064] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0065] Application scenario: In current technical practice, after the production of galvanized wire, strength testing is an essential step to verify whether it meets the specified performance standards. However, in the process of using test equipment to evaluate the strength of galvanized wire, some samples may suddenly break when subjected to high tension due to substandard quality or other factors. If the galvanized wire breaks under high tension, it may instantly release high-speed flying fragments, which may easily pose a safety threat to surrounding operators and damage the integrity of laboratory equipment.

[0066] like Figures 2 to 12 A finished galvanized wire tensile strength testing device shown includes a mobile frame 1 and also includes:

[0067] Two frames 2, the two frames 2 are fixedly installed on the top of the mobile frame 1;

[0068] A first clamp 3 is arranged between the two frames 2;

[0069] The second clamp 4 is disposed between the two frames 2, and the second clamp 4 is located below the first clamp 3;

[0070] The protection component is detachably installed between the two frames 2. The protection component includes two movable and combined shielding members. After the two shielding members are close to each other and combined and assembled, the two shielding members form a shielding space. If the galvanized wire is suddenly broken during the test of the first clamp 3 and the second clamp 4, the shielding space is used to shield the fragments of the galvanized wire when it breaks;

[0071] In the specific implementation, a section of galvanized wire to be tested is cut, and the two ends of the galvanized wire are clamped by the first clamp 3 and the second clamp 4 respectively, and the galvanized wire is straightened by adjusting the distance between the first clamp 3 and the second clamp 4. After the preparation is completed, the two shielding members are first controlled to approach each other and merge, so that the galvanized wire is located in the shielding space formed by the two shielding members, and then the first clamp 3 and the second clamp 4 are controlled to apply tension to the galvanized wire to test whether the production of the galvanized wire meets the standards;

[0072] If a sudden break occurs during the test, the shielding space formed by the shielding piece will block and intercept the flying debris, thereby helping to reduce the potential threat posed by the flying debris to operators and surrounding equipment. The design of the shielding piece is not only to immediately prevent the spread of debris, but more importantly, it helps to ensure that even at the moment of galvanized wire breaking, the scattered debris and galvanized wire will not easily escape the constraints of the shielding space, thereby helping to improve the overall safety of the test environment.

[0073] It should be noted that the first clamp 3 and the second clamp 4 are both existing technologies and are used in tests in various industries, so they will not be elaborated in detail here.

[0074] As a technical optimization solution of the present invention: the shielding member includes:

[0075] A fixing frame 5 is detachably fixed on the side wall of the frame 2;

[0076] The electric push rod 6 is fixedly mounted on a side of the fixing frame 5 away from the frame 2;

[0077] The shielding box 7 is fixedly mounted on the telescopic end of the electric push rod 6, and the upper and lower sides of the shielding box 7 are provided with a slot 19 with a diameter larger than the diameter of the galvanized wire;

[0078] Two semi-conical cylinders 8 are respectively fixedly installed inside the shielding box 7 and are respectively connected to the two card slots 19;

[0079] In the specific implementation, the electric push rod 6 is controlled to start pushing out, and the electric push rod 6 pushes the shielding boxes 7 at the corresponding positions to approach each other. When the two shielding boxes 7 approach each other and close, because the diameter of the card slot 19 on each shielding box 7 is slightly larger than the diameter of the galvanized wire, it is ensured that after the two card slots 19 are docked to form a complete channel, even if the galvanized wire is in a tensioned state, it will not contact the inner wall of the card slot 19. Through this design detail, it effectively avoids the potential interference of the card slot 19 on the test results of the mechanical properties of the galvanized wire, and ensures the accuracy and reliability of the test data;

[0080] Furthermore, in the process of merging the two semi-conical cylinders 8 into a complete conical cylinder, the principle of a diameter larger than the diameter of the galvanized wire is also followed, especially the narrowest end of the conical cylinder, which also maintains sufficient space to avoid direct contact with the galvanized wire. Such a structure not only ensures the free movement of the galvanized wire during the test, but also is not affected by the friction of the conical cylinder wall;

[0081] During the test, once the galvanized wire breaks accidentally, the resulting flying debris will be effectively intercepted and collected by the shielding box 7, significantly reducing the potential harm of the debris to the operating environment and personnel. In order to further enhance safety protection, a semi-conical cylinder 8 structure is specially added to the design, and the diameter of its narrowest end is smaller than the diameter of the slot 19. This ingenious conception ensures that even at the moment of breakage, on the one hand, it helps to prevent debris from flying out through the gap and reduce the probability of debris flying out. On the other hand, the galvanized wire will not escape from the shielding box 7 due to inertia. The semi-conical cylinder 8 will intercept the galvanized wire at the moment of breakage, which helps to steadily control the galvanized wire after breakage and prevent it from accidentally flying out of the shielding box 7, thereby greatly improving the safety factor of the entire test process.

[0082] As a technical optimization solution of the present invention: two sets of bias rubbing components are arranged inside the two shielding boxes 7, and the bias rubbing components include:

[0083] Two first electric push cylinders 9, the fixed parts of the two first electric push cylinders 9 are respectively fixedly connected to the inner walls of the two shielding boxes 7;

[0084] Two elastic telescopic rods 10 are respectively fixedly connected to the outer walls of the telescopic ends of the two first electric push cylinders 9;

[0085] Two slide rails 11 are fixedly connected to two elastic telescopic rods 10 respectively;

[0086] Two rubbing blocks 12 are respectively fixedly connected to the slide rails 11 at corresponding positions, and the rubbing blocks 12 are provided with a flat surface and an inclined surface;

[0087] Monitoring components, used to obtain vibration information and pressure information;

[0088] When the monitoring component obtains vibration information or pressure information, the two first electric push cylinders 9 are controlled to drive the two eccentric rubbing blocks 12 to approach each other, so as to complete the eccentric rubbing limit of the galvanized wire;

[0089] In the specific implementation, the above example illustrates that the fragments generated by the broken galvanized wire are intercepted by the shielding box 7 and the semi-conical cylinder 8. However, at the moment when the galvanized wire breaks, the two sections of galvanized wire may be thrown out directly from the inside of the shielding box 7 due to the inertia generated, thereby affecting the safety of the operator because the force of the galvanized wire is not fully released;

[0090] Therefore, after the galvanized wire breaks under stress, the monitoring component will obtain pressure information or vibration information, or both. No matter which situation occurs, the two first electric push cylinders 9 will be immediately controlled to start and push out. The two first electric push cylinders 9 drive the two eccentric rubbing blocks 12 to approach each other. When the two eccentric rubbing blocks 12 gradually approach each other, they will perform a unique rubbing action on the galvanized wire and play a positioning role at the same time. Considering that the galvanized wire is actually composed of many thin metal wire bundles tightly woven together, once the galvanized wire is broken, these tiny wire bundles will lose their constraints and are very likely to break in a sudden way. Spreading to the surroundings, this sudden release of energy may pose a potential threat to the surrounding semi-conical cylinder 8 or shielding box 7. However, it is precisely because of the fine kneading of the galvanized wire by the two rubbing blocks 12 during the gradual approach that they can not only exert precise force on the galvanized wire, effectively suppressing the dissipation tendency of those small wire bundles that are about to break, but also effectively control and position these wire bundles while kneading, which not only helps to reduce the risk of disorderly scattering of wire bundles at the moment of breakage, but also effectively prevents the possibility of the galvanized wire being accidentally ejected from the inside of the protective box under extreme circumstances.

[0091] It should be further explained that in the process of the two rubbing blocks 12 approaching each other, the inclined surfaces on the two rubbing blocks 12 will contact the outer wall of the galvanized wire, and the outer wall of the galvanized wire will be rubbed in the process of the two inclined surfaces approaching each other, which helps to suppress the divergence of the galvanized wire bundle, and because of the existence of the two inclined surfaces, extrusion force will be applied to the galvanized wire piece by piece in the process of approaching each other, which helps to limit the galvanized wire and prevent it from being thrown out.

[0092] As a technical optimization solution of the present invention: the monitoring component includes:

[0093] A plurality of vibration sensors are fixedly mounted on the inner wall of the semi-conical cylinder 8;

[0094] A plurality of pressure sensors are fixedly mounted on the inner wall of the semi-conical cylinder 8;

[0095] Among them, the vibration sensor and the pressure sensor are cross-distributed on the inner wall of the semi-conical cylinder 8;

[0096] In the specific implementation, vibration information is obtained by a vibration sensor, and pressure information is obtained by a pressure sensor. When the galvanized wire is not broken, the galvanized wire is in a straight state and has no contact with the semi-conical tube 8. However, after the galvanized wire is broken under force, the galvanized wire will inevitably contact with the semi-conical tube 8 due to the uncontrollability of the galvanized wire. Therefore, in theory, at least one of the vibration sensor and the pressure sensor will obtain relevant information, which will help the subsequent work.

[0097] As a technical optimization solution of the present invention: it also includes:

[0098] Two second electric push cylinders 13, the fixing parts of the two second electric push cylinders 13 are respectively fixedly connected to the inside of the shielding box 7;

[0099] Two push blocks 14 are respectively fixedly connected to the telescopic ends of the two second electric push cylinders 13;

[0100] Two slide plates 15 are respectively slidably connected to the sides of the two rubbing blocks 12 that are close to each other;

[0101] Two inclined grooves 16 are respectively provided on the two slide plates 15;

[0102] Two slide bars 17 are fixedly connected to the two push blocks 14 respectively, and the two slide bars 17 are slidably connected to the inside of the inclined groove 16;

[0103] In the specific implementation, when the first electric push cylinder 9 pushes the rubbing block 12 to move, a relative displacement will be generated between the slide plate 15 and the rubbing block 12. After the first electric push cylinder 9 is pushed out, the second electric push cylinder 13 will push the push block 14 to move. The push block 14 will first drive the slide plate 15 to slide at the bottom of the rubbing block 12. After sliding to the maximum moving distance, as the push block 14 continues to move, the push block 14 will drive the slide bar 17 to slide inside the inclined groove 16. Under the guidance of the inclined groove 16, the slide plate 15 will move downward. The slide plate 15 will drive the rubbing block 12 to compress the elastic telescopic rod 10 to move downward. The downward movement of the rubbing block 12 will drive the clamped limited galvanized wire to move downward, thereby helping to further avoid the probability of the galvanized wire flying out by pulling the galvanized wire downward for a certain distance.

[0104] As a technical optimization solution of the present invention: a groove 18 is formed on the two push blocks 14 on the left side, a clamping slot 19 is formed inside the groove 18, and a pointed block 20 is fixedly connected to the two push blocks 14 on the right side;

[0105] In a specific implementation, when the push blocks 14 located in different shielding boxes 7 approach each other, the pointed blocks 20 push the galvanized wire into the groove 18, so that the galvanized wire is bent in the groove 18, thereby helping to prevent the galvanized wire from escaping from the inside of the shielding box 7, and by bending the galvanized wire, it helps to bend the divergent wire bundle, thereby helping to prevent the wire bundle from flying again after losing the restriction;

[0106] In a more advanced operation stage, in order to enable the pointed block 20 to effectively guide the galvanized wire into the slot 19, the pre-set condition is that a section of the galvanized wire needs to be located below the pointed block 20. In this way, when the rubbing block 12 drives the galvanized wire to move downward, it can ensure that the galvanized wire is naturally placed under the pointed block 20, thereby laying the foundation for the next step - that is, the pointed block 20 works together with the preset groove 18 and the slot 19 to complete the precise bending of the galvanized wire, so as to help prevent the linear speed of the galvanized wire from diverging.

[0107] As a technical optimization solution of the present invention: it also includes:

[0108] Two sliding rods 21 are symmetrically slidably connected to the groove 18;

[0109] The extrusion members 22 are respectively fixedly connected to the ends of the two sliding rods 21 that are close to each other;

[0110] Two springs 23 are respectively fixedly connected between the extrusion member 22 and the groove 18 at corresponding positions, and the springs 23 are sleeved on the outer wall of the sliding rod 21;

[0111] In specific implementation, when the pointed block 20 moves toward the depth of the slot 19, it not only pushes forward itself, but also drives the extrusion pieces 22 on both sides to expand in opposite directions. During this process, the spring 23 is always in an active state, continuously applying a restoring force to the extrusion pieces 22 to ensure that they are closely attached to and press the outer surface of the galvanized wire. This continuous contact and pressure application is essentially a reshaping process for the galvanized wire. Through repeated and uniform extrusion, it helps to promote the formation of shape memory of the galvanized wire, ensuring that it can still maintain a predetermined bending shape after the pointed block 20 withdraws.

[0112] After the pointed block 20 withdraws from the groove 18, the extruded part 22 which loses its support will bend the galvanized wire again, and multiple bendings will help the galvanized wire to stably maintain the desired geometric shape without easily returning to its original state.

[0113] like Figure 1 A control method for a finished galvanized wire tensile strength detection device is shown, and the control method comprises the following steps:

[0114] Obtaining first parameter information;

[0115] Generate first control information according to the parameter information, the first control information is used to control the first electric push cylinder 9 to start pushing out;

[0116] The first control information is sent to the first electric push cylinder 9 to control the first electric push cylinder 9 to push the rubbing block 12 to move.

[0117] As a technical optimization solution of the present invention: the first parameter information includes vibration information and pressure information as well as vibration information or pressure information.

[0118] As a technical optimization solution of the present invention: it also includes:

[0119] When the first control information is generated, the second control information is also generated;

[0120] The second control information is sent to the second electric push cylinder 13 to control the second electric push cylinder 13 to start pushing out.

[0121] Working principle of the present invention:

[0122] Cut a section of galvanized wire to be tested, clamp the two ends of the galvanized wire by the first clamp 3 and the second clamp 4 respectively, and straighten the galvanized wire by adjusting the distance between the first clamp 3 and the second clamp 4. After the preparation is completed, first control the two shielding members to approach each other and merge, so that the galvanized wire is located in the shielding space formed by the two shielding members, and then control the first clamp 3 and the second clamp 4 to apply tension to the galvanized wire to test whether the production of the galvanized wire meets the standards;

[0123] If a sudden break occurs during the test, the shielding space formed by the shielding piece will block and intercept the flying fragments, thereby helping to reduce the potential threat posed by the flying fragments to operators and surrounding equipment. The design of the shielding piece is not only to immediately prevent the spread of fragments, but more importantly, it helps to ensure that even at the moment of galvanized wire breaking, the scattered fragments and galvanized wire will not easily escape from the constraints of the shielding space, thereby helping to improve the overall safety of the test environment.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
