Description

Technical Field

[0001] This invention belongs to the field of materials testing technology, specifically a toughness testing device for industrial wires. Background Technology

[0002] Industrial yarn toughness testing equipment is a specialized testing instrument used to determine the ability of industrial yarns such as polyester, nylon, and aramid to resist breakage or deformation under mechanical forces such as tension, bending, and impact. By accurately collecting key parameters such as force, elongation, and breaking work, it quantifies and evaluates the toughness index of industrial yarns to meet their quality control needs in high-end application scenarios such as tire cord, conveyor belts, and aerospace.

[0003] A search revealed a rapid testing device for industrial yarn toughness, disclosed in publication number CN219475206U. This device includes a base, two adjusting sliders housed within the base, and a pressure block assembly mounted on the adjusting sliders. The base contains a guide rod and a bidirectional lead screw, which pass through the adjusting sliders and are rotatably mounted within the base. This invention enables rapid testing of industrial yarn toughness, provides excellent clamping effect during testing, effectively reduces errors, improves the accuracy of test results, and features a simple overall structure and easy operation.

[0004] Although the above-mentioned device enables rapid testing of the toughness of industrial yarn, in actual testing, after the two ends of the industrial yarn are fixed, it is necessary to rotate the bidirectional lead screw for a long time to drive the two side adjustment sliders to move to both sides for tensile testing. Rotating the bidirectional lead screw is cumbersome, time-consuming and laborious, and can also cause hand fatigue for operators. Therefore, a toughness testing device for industrial yarn is proposed to address the above problems. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: an industrial yarn toughness testing device, comprising a base, and further comprising: a connecting block, which is disposed in the inner wall of the top end of the base via a tensioning mechanism; a pressing module is fixedly connected to the outer wall of the top end of the connecting block; a wire groove is formed on the outer wall of the connecting block; a crossbar is fixedly connected to the outer wall of the pressing module; a moving mechanism, which is disposed on the crossbar; a rubber block is disposed on the outer wall of the moving mechanism; and a reinforcing mechanism, which is disposed on the outer wall of the top end of the base. The tensioning mechanism includes a pull rod, the outer wall of which is hinged to a slider via a hinge rod, the inner wall of which is slidably connected to a pressure rod, the inner wall of which is elastically connected to a protrusion via a connecting spring, and the inner wall of which is slidably connected to a trapezoidal block.

[0007] Preferably, the inner wall of the pull rod is slidably connected to a slide rod, one end of which is slidably connected to the outer wall of the trapezoidal block, and the other end of which is fixedly connected to the outer wall of the protrusion.

[0008] Preferably, the pull rod is slidably connected to the inner wall of the base, the two ends of the hinge rod are respectively hinged to the outer walls of the pull rod and the slider, and the slider is fixedly connected to the bottom outer wall of the connecting block.

[0009] Preferably, the pressure rod is fixedly connected to the outer wall of the trapezoidal block, one end of the connecting spring is fixedly connected to the outer wall of the protrusion, the other end of the connecting spring is fixedly connected to the inner wall of the pull rod, the protrusion is slidably connected to the inner wall of the pull rod, and the protrusion is engaged with the groove on the inner wall of the base.

[0010] Preferably, the moving mechanism includes a moving block, a handle is fixedly connected to the outer wall of the top of the moving block, a partition is slidably connected to the outer wall of the handle, an insert is elastically connected to the inner wall of the moving block by a telescopic spring, a wheel is rotatably connected to the inner wall of the moving block, a pull rope is wound around the outer wall of the wheel, and a slot is opened on the inner wall of the crossbar.

[0011] Preferably, the movable block is engaged in the inner wall of the crossbar, the two ends of the pull rope are fixedly connected to the outer wall of the partition and the insert block respectively, and the insert block is engaged in the slot.

[0012] Preferably, one end of the telescopic spring is fixedly connected to the outer wall of the insert block, and the other end of the telescopic spring is fixedly connected to the inner wall of the movable block, and the insert block is slidably connected to the inner wall of the movable block.

[0013] Preferably, the reinforcement mechanism includes a fixing plate, the outer wall of which has a sliding groove, the inner wall of which is slidably connected to a sliding block, the inner wall of which has a square groove, the inner wall of which is elastically connected to a moving ring via a return spring, the outer wall of which is fixedly connected to a control ring, the inner wall of which is slidably connected to two sets of square blocks, the two sets of square blocks being elastically connected to each other via a spring, and the outer wall of which is fixedly connected to an inclined block.

[0014] Preferably, the fixing plate is fixedly connected to the top outer wall of the base, the square block is engaged with the square groove, the moving ring is slidably connected to the inner wall of the sliding block, and the control ring is slidably connected to the outer wall of the sliding block.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention utilizes a combination of a pull rod and a slider. By pressing the pull rod, the trapezoidal block causes the protrusion to disengage from the groove on the inner wall of the base, allowing the pull rod to be pushed inward. The hinge rod then flips, causing the connecting blocks on both sides to move to the sides. This allows for convenient and quick testing of the toughness of the industrial wire fixed on the connecting blocks, eliminating the need for prolonged operation by rotating the bidirectional threaded rod, making it more convenient and efficient. This invention, through the combination of partitions and insert blocks, allows the insert blocks to move into the inner wall of the moving block by pulling a rope when the partition is pulled. When the insert blocks disengage from the slot, the limiting position of the moving block is released, allowing it to move laterally in the crossbar. The position of the rubber block can be adjusted to correspond to the appropriate groove. It is simple to use and saves time and effort. This invention utilizes a combination of sliding blocks and square blocks. After the sliding block is fixed to the rubber block, when the connecting block moves to both sides, the sliding block will guide the rubber block to continue pressing down under the guidance of the sliding groove. The rubber block deforms and increases the pressure on the industrial wire, thereby improving the stability of the fixed ends of the industrial wire and preventing the industrial wire from separating from the rubber block during the stretching process, which would affect the detection.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 9 As shown, the present invention provides an industrial yarn toughness testing device, including a base 100, and further including: a connecting block 500, which is disposed in the inner wall of the top end of the base 100 via a tensioning mechanism 200; a pressing module 600 is fixedly connected to the outer wall of the top end of the connecting block 500; a wire groove 700 is formed on the outer wall of the connecting block 500; a crossbar 900 is fixedly connected to the outer wall of the pressing module 600; a moving mechanism 300, which is disposed on the crossbar 900; a rubber block 800 is disposed on the outer wall of the moving mechanism 300; and a reinforcing mechanism 400, which is disposed on the outer wall of the top end of the base 100. The tensioning mechanism 200 includes a pull rod 201, a slider 203 hinged to the outer wall of the pull rod 201 via a hinge rod 202, a pressure rod 204 slidably connected to the inner wall of the pull rod 201, a protrusion 207 elastically connected to the inner wall of the pull rod 201 via a connecting spring 206, and a trapezoidal block 205 slidably connected to the inner wall of the pull rod 201.

[0021] Using the above scheme: the two ends of the industrial wire to be tested for toughness and tensile strength can be pressed and fixed on the grooves 700 of the connecting blocks 500 on both sides by the pressing module 600. The industrial wire is fixed by the pressure generated by the rubber block 800. The bottom outer wall of the rubber block 800 has a horizontal groove perpendicular to the direction of the industrial wire, which can improve the friction of the industrial wire and prevent it from sliding during the stretching process. The stretching mechanism 200 can easily and quickly drive the connecting blocks 500 on both sides to move in the same or opposite directions to perform toughness testing. It does not require the rotation of the bidirectional threaded rod for testing, making it more convenient to use.

[0022] like Figures 2 to 3 As shown, a slide rod 208 is slidably connected to the inner wall of the pull rod 201. One end of the slide rod 208 is slidably connected to the outer wall of the trapezoidal block 205, and the other end of the slide rod 208 is fixedly connected to the outer wall of the protrusion 207. The pull rod 201 is slidably connected to the inner wall of the base 100. The two ends of the hinge rod 202 are respectively hinged to the outer walls of the pull rod 201 and the slider 203. The slider 203 is fixedly connected to the bottom outer wall of the connecting block 500. The pressure rod 204 is fixedly connected to the outer wall of the trapezoidal block 205. One end of the connecting spring 206 is fixedly connected to the outer wall of the protrusion 207, and the other end of the connecting spring 206 is fixedly connected to the inner wall of the pull rod 201. The protrusion 207 is slidably connected to the inner wall of the pull rod 201 and is engaged with the groove on the inner wall of the base 100.

[0023] Using the above scheme: the pull rod 201 can slide back and forth in the inner wall of the base 100. When it moves, it drives the connecting end of the hinge rod 202 to move synchronously. The other end of the hinge rod 202 drives the slider 203 to move. Since the slider 203 can only move laterally synchronously with the connecting block 500, the hinge rod 202 will flip and drive the slider 203 and the connecting block 500 to move to the sides or the middle at the same time. Under normal conditions, the protrusion 207 on the inner wall of the pull rod 201 is kept in an upward pop-out state due to the elastic force of the connecting spring 206. The rod 201 is fixed by engaging with the groove on the inner wall of the base 100, thereby fixing the initial position of the slider 203 and the connecting block 500. At this time, the slider 208 contacts the top of the inclined surface of the trapezoidal block 205. When the pressing rod 204 is pressed, the trapezoidal block 205 will move accordingly. Since the slider 208 can only move vertically, it will move downward along the inclined surface of the trapezoidal block 205 and drive the protrusion 207 to move downward synchronously, compressing the connecting spring 206, thereby releasing the limit of the rod 201, and it can be pulled back and forth.

[0024] like Figures 4 to 6 As shown, the moving mechanism 300 includes a moving block 301. A handle 303 is fixedly connected to the outer wall of the top of the moving block 301. A partition 302 is slidably connected to the outer wall of the handle 303. An insert block 305 is elastically connected to the inner wall of the moving block 301 through a telescopic spring 304. A rotating wheel 306 is rotatably connected to the inner wall of the moving block 301. A pull rope 307 is wound around the outer wall of the rotating wheel 306. A slot 308 is opened on the inner wall of the crossbar 900.

[0025] Using the above scheme: the movable block 301 can be connected and fixed to the crossbar 900 through the insert block 305 and the slot 308. The bottom end of the movable block 301 is slidably connected to the bottom outer wall of the rubber block 800, and the rubber block 800 can move up and down to a certain extent. The wire groove 700 has multiple sets to accommodate industrial wires of different thicknesses. When fixing different industrial wires, the position can be adjusted by moving the movable block 301 laterally in the crossbar 900. The adjustment operation is relatively convenient and does not require adjustment by rotating the bolt, saving time and effort.

[0026] like Figures 4 to 6 As shown, the movable block 301 is snapped into the inner wall of the crossbar 900, and the two ends of the pull rope 307 are fixedly connected to the outer walls of the partition 302 and the insert block 305, respectively. The insert block 305 is snapped into the slot 308. One end of the telescopic spring 304 is fixedly connected to the outer wall of the insert block 305, and the other end of the telescopic spring 304 is fixedly connected to the inner wall of the movable block 301. The insert block 305 is slidably connected in the inner wall of the movable block 301.

[0027] Using the above solution: Under normal conditions, the insert block 305 pops out due to the elastic force of the telescopic spring 304 and engages with the slot 308, fixing the position of the moving block 301. The operator can hold the handle 303 and pull the partition 302 upward. The partition 302 can drive one end of the pull rope 307 to move synchronously. The pull rope 307 changes the direction of the pulling force after passing through the rotating wheel 306, and the rotating wheel 306 will rotate to reduce wear. Its other end will pull the corresponding insert block 305 to move into the inner wall of the moving block 301, compressing the telescopic spring 304 and disengaging from the slot 308, thus releasing the limitation of the moving block 301 and moving it. After moving to the appropriate position, the partition 302 is released, and the telescopic spring 304 can drive the insert block 305 to pop out and engage with the slot 308 to complete the adjustment.

[0028] like Figures 7 to 9 As shown, the reinforcement mechanism 400 includes a fixing plate 401. The outer wall of the fixing plate 401 is provided with a sliding groove 402. The inner wall of the sliding groove 402 is slidably connected to a sliding block 403. The inner wall of the rubber block 800 is provided with a square groove 404. The inner wall of the sliding block 403 is elastically connected to a moving ring 406 through a return spring 405. The outer wall of the moving ring 406 is fixedly connected to a control ring 407. The inner wall of the sliding block 403 is slidably connected to two sets of square blocks 408. The two sets of square blocks 408 are elastically connected to each other through a spring. The outer wall of the square block 408 is fixedly connected to an inclined block 409.

[0029] The above scheme employs the following: Two sets of fixing plates 401 are provided, corresponding to the positions of the connecting blocks 500 on both sides. Through the reinforcement mechanism 400, when the pull rod 201 moves the connecting blocks 500 to both sides, the pressure of the rubber block 800 on the industrial wire is automatically increased, thereby further improving the stability of both ends of the industrial wire during the stretching process and preventing it from detaching from the rubber block 800 and connecting block 500, thus affecting the detection. The slide groove 402 has inclined and straight sections. The sliding block 403 can move within the inner wall of the slide groove 402, and the other end of the sliding block 403 can be fixed to the inner wall of the rubber block 800 via a square block 408 and a square groove 404. When the connecting block 500 and the rubber block 800 move, the sliding block 403 moves synchronously along the inner wall of the slide groove 402. Under normal conditions, the springs between the square blocks 408 keep the two sets of square blocks 408 in a pop-out state. The square block 408 causes the inclined surface of the inclined block 409 to contact the inner wall of the moving ring 406. The moving ring 406 and the control ring 407 are fixed by a connecting rod, which passes through the outer wall of the sliding block 403. The moving control ring 407 can then drive the moving ring 406 to move within the inner wall of the sliding block 403. When the moving ring 406 moves, it will press the inclined surface of the inclined block 409. Since the square block 408 can only move vertically, it will cause the inclined block 409 and the square block 408 to move simultaneously towards the center into the inner wall of the sliding block 403. This allows the sliding block 403 to be inserted into the rubber block 800 or removed from the inner wall of the rubber block 800. When the sliding block 403 is inserted into the position corresponding to the square block 408 and the square groove 404, the square block 408 will pop out due to the spring force and engage with the square groove 404, thus completing the fixation of the sliding block 403 and the rubber block 800.

[0030] like Figures 7 to 9 As shown, the fixing plate 401 is fixedly connected to the top outer wall of the base 100, the square block 408 is engaged with the square groove 404, the moving ring 406 is slidably connected to the inner wall of the sliding block 403, and the control ring 407 is slidably connected to the outer wall of the sliding block 403; one end of the return spring 405 is fixedly connected to the outer wall of the moving ring 406, the other end of the return spring 405 is slidably connected to the inner wall of the sliding block 403, and the inclined block 409 is in contact with the inner wall of the moving ring 406.

[0031] Using the above scheme: When the connecting block 500 is in the initial position, the sliding block 403 contacts one end of the inclined segment of the slide groove 402 and is connected and fixed to the rubber block 800. The square block 408 is inserted into the square groove 404 due to the spring force. When the connecting block 500 moves to both sides, the sliding block 403 will move along the inclined segment of the slide groove 402 towards the straight segment. Since the sliding block 403 will drive the rubber block 800 to move synchronously, and the rubber block 800 can only move vertically within the inner wall of the moving block 301, when the sliding block 403 moves, the rubber block 800... 00 will continue to move downwards. Since it is already in contact with the top outer wall of the industrial filament and connecting block 500, it will undergo a certain deformation under pressure, thereby increasing the pressure on the industrial filament. When the connecting block 500 continues to move, the sliding block 403 moves into the straight section of the groove 402, keeping the position of the rubber block 800 moving. This will automatically increase and maintain the pressure on the industrial filament during the stretching process, improving the stability of the industrial filament. The end of the sliding block 403 away from the square block 408 is a telescopic rod, and its length can be freely adjusted according to the position of the moving block 301.

[0032] Working principle and usage process of this invention: Place both ends of the industrial wire to be tested into the appropriately sized wire grooves 700 of the connecting blocks 500 on both sides. Depending on the thickness of the industrial wire, hold the handle 303 and pull the partition 302 to drive the insert block 305 out of the slot 308. Move the moving block 301 and the rubber block 800 synchronously. After the rubber block 800 moves to the position corresponding to the industrial wire, release it, and the insert block 305 resets and engages with the slot 308. Then, the moving control ring 407 drives the moving ring 406 to press the inclined block 409, so that the square block 408 moves into the inner wall of the sliding block 403. Then, insert one end of the sliding block 403 into the rubber block 800, release the control ring 407, and the square block 408 pops out and engages with the square groove 404, completing the fixation of the sliding block 403 and the rubber block 800.

[0033] Next, press the pressure rod 204 to move the trapezoidal block 205. The slide rod 208 pulls the protrusion 207 down to release the engagement with the groove of the base 100 and release the movement restriction of the pull rod 201. Push the pull rod 201, and the pull rod 201 drives the hinge rod 202 to flip. The hinge rod 202 pushes the slider 203 and the connecting block 500 to move synchronously to both sides to apply tensile force to the industrial wire and perform toughness testing.

[0034] When the connecting block 500 moves, the rubber block 800 drives the sliding block 403 to move along the inclined section of the slide groove 402 of the fixed plate 401. The sliding block 403 pulls the rubber block 800 down and presses the industrial wire. The rubber block 800 deforms to increase friction and pressure. When the sliding block 403 enters the straight section of the slide groove 402, it keeps the rubber block 800 pressed and continues to stretch the industrial wire until the toughness test is completed.

[0035] After the test is completed, the pull rod 201 can be pulled in the opposite direction to return the connecting block 500 to its initial position. The protrusion 207 is reset and locked by the connecting spring 206, locking the pull rod 201. The sliding block 403 is reset to the initial end of the inclined section of the slide groove 402 along with the rubber block 800. The rubber block 800 is lifted to release the pressure and the tested industrial filament sample can be removed.
