Description

Technical Field

[0001] This utility model relates to the technical field of strength testing equipment, specifically a tire production strength testing device. Background Technology

[0002] In tire manufacturing, tire cord fabric is a key material constituting the tire skeleton. Its tensile strength, fatigue resistance, and other mechanical properties directly determine the tire's load-bearing capacity, durability, and safety. Therefore, rigorous and accurate strength testing of the cord fabric material during production is a crucial quality control step. Currently, common tensile testing machines typically employ a uniaxial tensile testing method on a single specimen. Each test can only process one sample, resulting in low testing efficiency. This makes it difficult to meet the needs of rapid sampling inspection of batches of samples on production lines, and it is also inconvenient to compare test results across the same batch of samples, making the test results unintuitive.

[0003] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a tire production strength testing device, which improves the efficiency of sample testing and facilitates cross-sectional comparison of test results for samples from the same batch.

[0005] This utility model is achieved through the following technical solution: a tire production strength testing device, including a base and a sample, a gantry frame is installed on the base, and a control panel is installed on the side of the gantry frame, characterized in that: a tension structure is installed on the top beam of the gantry frame, and clamps are installed on the lower end of the tension structure and on the base, and the sample is movably installed in an n-shape on two of the clamps, and the two clamps are installed symmetrically to each other;

[0006] Each of the fixtures includes a column, a rectangular base is mounted on one end of the column, and two rectangular clamping cavities are symmetrically opened on the rectangular base. Each rectangular clamping cavity is provided with a clamping plate. The clamping plate is adjusted for locking position by a locking component on the rectangular base. The sample is movably inserted into the two rectangular clamping cavities in an n-shape.

[0007] The locking assembly includes a screw, which is threadedly inserted into the side wall of the rectangular seat and extends into the rectangular clamping cavity. A connecting seat is movably fitted at one end of the screw inside the rectangular clamping cavity. The connecting seat is fixedly inserted into the clamping plate. A first guide rod is fixedly installed on the clamping plate and is movably inserted into the side wall of the rectangular seat.

[0008] In the above scheme: the tensioning structure includes a hydraulic cylinder, which is fixedly inserted into the top beam of the portal frame. A tension sensor is installed at the telescopic end of the hydraulic cylinder, and a crossbeam is installed at one end of the tension sensor. The two clamps are respectively installed on the lower wall of the crossbeam and the upper wall of the base.

[0009] In the above scheme: a second guide rod is installed between the base and the top beam of the portal frame, and the cross frame is movably fitted onto the second guide rod.

[0010] The tire production strength testing equipment provided by this utility model has the following advantages compared with the prior art: by passing the sample through the upper and lower symmetrical double clamps in an n-shaped path, a continuous sample is transformed into two samples with the same stress state for synchronous testing, which improves the efficiency of sample testing, facilitates the horizontal comparison of test results of samples in the same batch, and makes the test results intuitive.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example 1

[0018] like Figure 1-4 As shown, a tire production strength testing device includes a base 1 and a sample 9. A gantry frame 2 is installed on the base 1, and a control panel 3 is installed on the side of the gantry frame 2. A tension structure is installed on the top beam of the gantry frame 2. Fixtures 4 are installed on both the tension structure and the base 1. The sample 9 is movably installed in an n-shape on two fixtures 4, and the two fixtures 4 are installed symmetrically to each other.

[0019] The device is set at the target location via base 1 and connected to a power source. The control panel 3 has a built-in microcontroller that can be programmed with software. By writing the control program, the device can be controlled. Since this is existing technology, it will not be described in detail here.

[0020] Specifically, each fixture 4 includes a column 401, with a rectangular base 402 mounted at one end of the column 401. The rectangular base 402 is supported on the upper surface of the base 1 or on the tension structure via the column 401. There is a gap between the lower end of the lower rectangular base and the upper surface of the base 1, and a gap between the top surface of the upper rectangular base and the tension structure. Figure 1 As shown, two rectangular clamping cavities 403 are symmetrically formed on the rectangular base 402. Each rectangular clamping cavity 403 is equipped with a clamping plate 404. The clamping plate 404 is adjusted in a locking position by a locking assembly installed on the rectangular base 402. The sample 9 is n-shaped and movably inserted into the two rectangular clamping cavities 403.

[0021] Prepare a tire cord of sufficient length as sample 9. When the tensioning structure lowers the clamp 4 on it to its lowest position, sample 9 can be movably inserted into the two rectangular clamping cavities 403 of the upper and lower clamps 4 in an n-shape. Figure 4 As stated above, and the width of sample 9 is not greater than the width of rectangular clamping cavity 403, after sample 9 passes through the two clamps 4, the locking assembly of clamp 4 on base 1 is operated first.

[0022] The locking assembly includes a screw 405, which is threadedly inserted into the side wall of the rectangular seat 402 and extends into the rectangular clamping cavity 403. One end of the screw 405 located inside the rectangular clamping cavity 403 is movably fitted with a connecting seat 406, which is fixedly inserted into the clamping plate 404. A first guide rod 407 is fixedly installed on the clamping plate 404 and is movably inserted into the side wall of the rectangular seat 402.

[0023] Rotate the screws 405 on both sides. The screws 405 are screwed into the rectangular clamping cavity 403 under the connection of the threads. One end of the screw 405 may not be threaded, so that it can rotate in the connecting seat 406. Under the limit of the first guide rod 407, push the clamping plate 404 to move towards the sample 9, so that both ends of the sample 9 are clamped.

[0024] Preferably, and further, a handle 408 is installed at one end of the screw 405 outside the rectangular base 402 to facilitate the rotation of the screw 405;

[0025] As a preferred and further option, the side wall of the clamping plate 404 facing away from the screw 405 is provided with a first anti-slip texture 409; the side wall of the rectangular clamping cavity 403 facing the clamping plate 404 is provided with a second anti-slip texture 410; these are used to increase the friction between the sample 9 and the clamping plate 404 and the rectangular clamping cavity 403.

[0026] The tensioning structure includes a hydraulic cylinder 5, which is fixedly inserted into the portal frame 2. A tension sensor 6 is installed at the telescopic end of the hydraulic cylinder 5, and a crossbeam 7 is installed at one end of the tension sensor 6. Two clamps 4 are respectively installed on the lower wall of the crossbeam 7 and the upper wall of the base 1. A second guide rod 8 is installed between the base 1 and the portal frame 2. The crossbeam 7 is movably fitted onto the second guide rod 8 to support and guide the crossbeam 7 and protect the tension sensor 6.

[0027] The operator starts the tensioning structure via control panel 3, causing the extension end of hydraulic cylinder 5 to retract, driving the crossbeam 7 and the clamp 4 mounted on it upwards. Since the top of sample 9 passes through the two rectangular clamping cavities 403 of the upper clamp 4 but is not locked, sample 9 is tensioned as the upper clamp 4 moves upwards, and the overall tension of sample 9 is the same. When the tension sensor 6 detects that the tension value has reached the set value, hydraulic cylinder 5 stops retracting. Then, the locking assembly of clamp 4 on the tensioning structure is operated to lock the top of sample 9, turning what was originally one sample 9 into two samples with the same initial tension, both rigidly fixed at both ends. Hydraulic cylinder 5 then continues to retract, continuing the strength test. (The last sentence appears to be incomplete and possibly refers to a separate process.) Two cameras are installed to record the tensile force value displayed on the control panel 3 and the deformation process of sample 9. The video can be reviewed to see the tensile force value when one sample breaks. When both samples break, the tensile force value changes abruptly, at which point the hydraulic cylinder 5 stops extending. The control panel 3 records the tensile force value at this time. Normally, since the two samples 9 are tire cord fabrics produced under the same conditions, both samples 9 will break at the same time. This is the ultimate tensile strength of sample 9. If breakage occurs sequentially, it indicates an abnormality in the tire cord fabric production process, prompting staff to inspect the tire cord fabric production steps. This improves the efficiency of sample 9 testing and facilitates horizontal comparison of test results for samples 9 in the same batch. The test results are intuitive.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
