Description
Technical Field
[0001] This invention relates to the field of rubber production equipment technology, specifically to a multi-angle rubber tensile testing device. Background Technology
[0002] Rubber, a crucial material widely used in industrial manufacturing, transportation, medical equipment, and daily life, directly impacts the reliability, durability, and safety of final products through the stability of its quality and performance. During the production of rubber products, every step, from raw material selection to molding, can affect the final product's performance. Therefore, after production, rubber must undergo a series of rigorous testing methods to evaluate its physicochemical and mechanical properties, including key indicators such as tensile strength, elongation at break, hardness, abrasion resistance, aging resistance, and chemical corrosion resistance. These tests not only verify whether the rubber material meets design standards but also ensure that each batch of products exhibits highly consistent strength and performance, effectively guaranteeing product quality, meeting the stringent requirements of different application scenarios, and simultaneously improving production efficiency and reducing quality risks.
[0003] A rubber tensile testing device is a high-precision professional instrument specifically designed for testing the mechanical properties of rubber materials. It is widely used in key areas such as rubber product manufacturing, technology research and development, and product quality control. The core function of this device is to simulate the tensile, compression, and complex deformation processes experienced by rubber materials in real-world applications, thereby accurately measuring a series of important mechanical parameters, including elastic modulus, tensile strength, and elongation at break. Accurate acquisition of these parameters provides reliable experimental evidence and scientific support for the performance evaluation, quality verification, and subsequent material improvement of rubber materials. In the specific testing process, the rubber sample is firmly clamped between specialized fixtures on the device. As the tensile mechanism is activated, the sample is gradually stretched and elongated under controlled conditions until it breaks. The data recorded during the test comprehensively reflects the tensile properties and deformation behavior of the rubber. The results can not only be used to optimize material formulations and improve production processes, but also effectively verify whether products meet relevant national or industry technical standards.
[0004] However, traditional rubber tensile testing devices typically only possess a single bidirectional tensile function, with their structural design primarily focusing on vertical mechanical testing. This results in a significant deficiency in detecting tensile deformation in the transverse (horizontal) direction. This structural limitation not only restricts the overall applicability of the device but also prevents a comprehensive and accurate assessment of the actual performance of rubber materials under complex multi-directional stress states. Particularly in applications requiring high transverse tensile strength, such as high-performance seals and rubber components under complex stress environments, traditional devices struggle to meet precise testing needs, thus affecting the integrity and reliability of material performance data. To address this issue, a multi-angle rubber tensile testing device is proposed. Summary of the Invention

[0018] The technical solutions of the embodiments 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.
[0019] The embodiments of the present invention will now be described.
[0020] A multi-angle rubber tensile testing device, such as Figures 1 to 8 As shown, it includes a support component 100, a rotating component 200 is mounted on the top of the support component 100, a moving component 300 is connected to the top of the rotating component 200, a lower limit component 400 is provided on the top of the moving component 300, an upper limit component 500 is mounted on the top of the lower limit component 400, and a clamping component 600 is mounted on the top of the upper limit component 500. The clamping components 600 are in multiple sets, and the multiple sets of clamping components 600 are arranged in an array along the circumferential direction of the bearing component 100; During operation, the operator places the rubber product to be tested onto the clamping assembly 600. The equipment is equipped with a total of 10 clamping assemblies 600. The operator can flexibly adjust the placement and angle of the rubber product on the clamping assembly 600 according to its specific shape and the tensile testing direction specified in the testing requirements, ensuring the accuracy and relevance of the test. After the position adjustment is completed, the operator releases the mechanical limit of the bearing assembly 100 on the rotating assembly 200, allowing the rotating assembly 200 to freely perform circular motion along a preset trajectory. The circular motion of the rotating assembly 200 further drives the moving assembly 300 to generate a corresponding horizontal displacement. Under the dual guidance and restriction of the upper limit assembly 400 and the lower limit assembly 500, this series of movements ultimately drives all the clamping assemblies 600 to simultaneously perform a stable and uniform clamping operation on the rubber product, applying a continuous tensile force after clamping, thus achieving multi-directional and multi-angle tensile testing of the rubber product. Since the ten clamping components 600 have completely identical structural designs, and their movement trajectories and applied clamping forces are highly synchronized and consistent, they can effectively and reliably test the tensile force values of rubber products at different angles and directions, providing comprehensive and accurate data support for material performance evaluation.
[0021] Please refer to this carefully. Figures 1 to 3The supporting component 100 includes a base 110 placed on the ground. A scale 120 is connected to the top of the base 110. A scale ruler 130 is opened at the top of the scale 120. A limiting hole 140 is opened inside the scale ruler 130 and extends to the bottom of the scale 120. A limiting rod 150 is installed inside the limiting hole 140. A limiting plate 160 is fixedly connected to the top of the limiting rod 150. A dome block 170 is assembled at the center of the top of the scale 120. A number label is affixed inside the scale ruler 130. There are eighty sets of scale rulers 130. The eighty sets of scale rulers 130 are arranged in a row along the circumference of the scale 120. The dome block 170 is a conical cylinder with a larger bottom and a smaller top. A support arm is assembled on the side wall of the base 110 to fix the lower limiting component 400 and the upper limiting component 500. The rotating assembly 200 includes a rotating disk 210 that fits against the outer wall of the dome block 170. The top of the rotating disk 210 is provided with a first guide groove 220 that extends to its bottom. There are ten sets of first guide grooves 220, which are arranged in an array along the circumference of the rotating disk 210. The outer wall of the rotating disk 210 is fitted with a limiting block 230. The top of the limiting block 230 is provided with a through hole that extends to its bottom. The through hole matches the outer wall of the limiting rod 150. In the specific operational process of the above structural design, the operator first fully pulls the limiting rod 150 out of the limiting block 230 to release the original mechanical limiting state of the rotating disk 210. Then, according to the specific tensile force requirements specified in the rubber product testing items, the operator manually controls the rotating disk 210 to rotate smoothly in the circumferential direction. During this rotation, the operator must closely observe the scale 130 marked on the dial 120 and compare the correspondence between the rotation angle and the tensile force in real time. When the value displayed on the scale 130 gradually approaches and eventually matches the required tensile force, the operator must accurately insert the limiting rod 150 into the through hole inside the limiting block 230 and continue to apply downward force until the outer wall of the limiting rod 150 completely matches the inner wall of the limiting hole 140. At this time, the bottom end of the limiting plate 160 also fits tightly against the top end of the limiting block 230, thereby achieving precise locking of the rotating disk 210. In this state, the entire equipment remains stationary, and staff can conduct stable monitoring of the tensile force on the rubber product according to the duration specified in the testing standards, while observing its deformation characteristics and other related performance in detail, and recording the experimental data in real time.
[0022] Please refer to this carefully. Figures 1 to 5The moving component 300 includes a sliding shaft 310 that fits against the inner wall of the first guide groove 220. A sliding piece 320 is rotatably connected to the top of the sliding shaft 310. A connecting shaft 330 is assembled at the top of the sliding piece 320. There are ten sets of moving components 300. The ten sets of moving components 300 are equidistantly arranged along the circumference of the rotating disk 210. The sliding piece 320 is generally in the shape of a fan-shaped block. The lower limit assembly 400 includes a first limit plate 410 that fits against the top of the sliding piece 320. The top of the first limit plate 410 is provided with a second guide groove 420 that extends through to its bottom. There are ten sets of second guide grooves 420. The ten sets of second guide grooves 420 are equidistantly arranged along the circumferential direction of the first limit plate 410. The inner wall of the second guide groove 420 matches the outer wall of the connecting shaft 330. The upper limit assembly 500 includes a second limit plate 510 that fits against the outer wall of the clamping assembly 600. The top of the second limit plate 510 is provided with a third guide groove 520 that extends through to its bottom. The third guide groove 520 is arranged parallel to the second guide groove 420. In the aforementioned mechanical structure, the rotational motion of the rotating component 200 precisely drives the sliding shaft 310 to move; the movement of the sliding shaft 310 further pushes the sliding piece 320 to produce a corresponding displacement; the movement of the sliding piece 320 in turn causes the connecting shaft 330 to translate; the displacement of the connecting shaft 330 is ultimately transmitted to the clamping component 600, driving it to move accordingly. Since the outer walls of the lower limit component 400 and the upper limit component 500 are firmly connected to the outer wall of the bearing component 100, forming a stable support structure, and the bottom end of the clamping component 600 is directly connected to the top end of the connecting shaft 330, the connecting shaft 330 and the clamping component 600 are precisely guided and limited by the second guide groove 420 and the third guide groove 520 provided inside the lower limit component 400 and the upper limit component 500 during the movement, thereby ensuring that they move smoothly and accurately along the preset trajectory.
[0023] Please refer to this carefully. Figures 1 to 8The clamping assembly 600 includes a driven shaft 610 connected to the connecting shaft 330. A clamping housing 620 is fitted onto the outer wall of the driven shaft 610. A welding block 630 is mounted on the outer wall of the clamping housing 620. A tension spring 640 is fixedly connected to the outer wall of the welding block 630. A first limiting shaft 650 is provided at one end of the welding block 630 near the clamping housing 620. A spring 660 is fixed to the outer wall of the first limiting shaft 650. There are two sets of springs 660. A fixing member 670 is fitted at the middle position of each spring 660. A first clearance groove is formed on the outer wall of the clamping housing 620, extending through to its inner wall. The first clearance groove matches the spring 660. The outer wall of the clamping housing 620 is located... The first relief groove has a second relief groove on both sides that extends into the clamping housing 620. The fixing member 670 includes a first swing arm 671 that is rotatably connected to the outer wall of the first limiting shaft 650. The bottom end of the first swing arm 671 is equipped with a second swing arm 672. The end of the second swing arm 672 away from the first swing arm 671 is equipped with a first clamping arm 673. The top end of the first clamping arm 673 is connected to a second limiting shaft 674. The top end of the first swing arm 671 is equipped with a second clamping arm 676. The top end of the second clamping arm 676 is provided with a fourth limiting shaft 677. A third limiting shaft 675 is equipped at the intersection of the second clamping arm 676 and the first clamping arm 673. In the design process of the above mechanical structure, when the connecting shaft 330 is displaced and drives the clamping assembly 600 to move as a whole, the driven shaft 610 inside the clamping assembly 600 moves accordingly. The displacement of the driven shaft 610 further drives the clamping housing 620 to produce a corresponding action, and the movement of the clamping housing 620 causes the welding block 630 to move laterally. Since one end of the tension spring 640 is connected to the welding block 630, while the other end is fixed to the top of the upper limit assembly 500, the lateral movement of the welding block 630 will directly cause the tension spring 640 to be stretched. While the tension spring 640 is stretched, the resulting reverse force is applied to the welding block 630. This force causes the welding block 630 to push the first limiting shaft 650 downward along the first relief groove during its lateral displacement. The downward movement of the first limiting shaft 650 further compresses the spring 660, and also causes the first swing arm 671 and the second swing arm 672 to move in a fan-shaped trajectory around the first limiting shaft 650. As the first swing arm 671 and the second swing arm 672 move, under the guidance and constraint of the second clearance groove, the first clamping arm 673 and the second clamping arm 674 move in opposite arcs, exhibiting a scissor-like opening and closing motion. This motion process first achieves stable clamping of the rubber product through the first clamping arm 673 and the second clamping arm 674, thus providing a foundation for subsequent operations: when the clamping assembly 600 continues to move, a continuous tensile force can be applied through this assembly to complete the tensile performance test of the rubber material.
