Description

Technical Field

[0001] This invention relates to the field of rubber seal strength testing technology, specifically to a rubber seal strength testing device. Background Technology

[0002] In modern industry, rubber seals are widely used in various fields such as automobiles, aerospace, petrochemicals, and machinery manufacturing. They play a crucial role in sealing systems, preventing the leakage of liquids and gases and ensuring the normal operation and efficiency of equipment. However, the performance and quality of rubber seals directly affect the sealing effect. Strength, as one of the key performance indicators of rubber seals, is particularly important to test. Among them, tensile length and elongation at break are key indicators reflecting the strength of rubber seals. By testing tensile length and elongation at break, we can understand the basic mechanical properties of the material and determine whether it meets the requirements of a specific application.

[0003] Utility model patent CN216718032U discloses a rubber sealing ring strength testing device. By fitting the rubber sealing ring to be tested onto two placement rods and then activating a telescopic drive, a moving block is moved to the right. This allows the right placement rod to pull the rubber sealing ring, and vice versa. A pressure detection device can then detect the pressure generated by the left placement rod through a fixed block, thus detecting the tensile force on the rubber sealing ring and consequently its strength. However, this patent has the following problems in practical use: While this rubber seal strength testing equipment can detect the tensile force on a rubber seal to determine its strength, it faces challenges when testing its tensile properties. Rubber seals are typically made of elastomers (such as NBR, FKM, VMQ, etc.), and their internal components may contain microscopically uneven distributions of fillers, plasticizers, etc., leading to differences in local modulus and stress response. Furthermore, during stretching, the seal's cross-section shrinks (stretching by one percent reduces the cross-sectional diameter by approximately 0.5%), resulting in changes in cross-sectional area and uneven stress distribution along the length. Therefore, relying solely on transverse stretching cannot accurately determine the tensile properties of the rubber seal, thus affecting the accuracy of the test data.

[0004] Therefore, a rubber sealing ring strength testing device is proposed to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a rubber sealing ring strength testing device to solve the problem mentioned in the background art: when testing the tensile properties of rubber sealing rings, since rubber sealing rings are usually made of elastomers, there may be microscopic non-uniform distribution of fillers, plasticizers, and other components inside, leading to differences in local modulus and stress response. At the same time, during the stretching process, the sealing ring cross-section will shrink, resulting in changes in cross-sectional area, which in turn causes uneven stress distribution along the length direction. Therefore, it is impossible to accurately determine the tensile properties of rubber sealing rings by transverse stretching alone, thus affecting the accuracy of the test data.

[0018] 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.

[0019] Please see Figures 1-5 , Figure 9 A rubber sealing ring strength testing device includes a uniform testing mechanism 1 and a stabilizing tension mechanism 2, wherein the stabilizing tension mechanism 2 is disposed at the bottom of the uniform testing mechanism 1.

[0020] The uniformity detection mechanism 1 includes two sliding supports 101. Each sliding support 101 has a limiting sliding rod 102 fixedly installed inside it. Each limiting sliding rod 102 has a limiting sliding sleeve 103 slidably connected to its outer side. Each limiting sliding sleeve 103 has a limiting plate 104 fixedly installed on its top. One limiting plate 104 has a first roller bracket 105 fixedly installed on its top, and the other limiting plate 104 has a second roller bracket 104 fixedly installed on its top. The first roller bracket 105 has a drive motor 106 fixedly installed on its top. The output end of the drive motor 106 is fixedly connected to a first drive roller 107, which is rotatably connected to the first roller bracket 101. Inside 5, the second roller bracket 111 is rotatably connected to the second drive roller 112. The outer sides of the first drive roller 107 and the second drive roller 112 are both provided with limiting rotation grooves 108. The rubber sealing ring 126 is sleeved in the limiting rotation grooves 108 of the first drive roller 107 and the second drive roller 112. The limiting rotation grooves 108 can limit the rubber sealing ring 126 when it is stretched, so that the rubber sealing ring 126 always maintains a horizontal position when stretched, improving the accuracy of the stretching test. When the rubber sealing ring 126 is stretched, the first roller bracket 105 and the second roller bracket 111 are limited and slid under the action of the limiting sliding rod 102 and the limiting sliding sleeve 103.

[0021] Please see Figures 2-7 A smart pressure detection device 109 is fixedly installed on one side of the first roller bracket 105 and the second roller bracket 111. The end of the smart pressure detection device 109 closest to the first roller bracket 105 and the second roller bracket 111 is the pressure sensing end. The end of the smart pressure detection device 109 furthest from the first roller bracket 105 and the second roller bracket 111 is fixedly installed with a support plate 110. The support plate 110 and the sliding bracket 101 are both fixedly installed on the top of the detection chassis 127.

[0022] Adjustable brackets 113 are fixedly installed on the side of each of the two detection chassis 127 away from the sliding bracket 101. An adjusting knob 114 is rotatably connected to the end of each adjusting bracket 113. An adjusting threaded rod 115 is fixedly connected to the end of each adjusting knob 114. An adjusting threaded sleeve 116 is threadedly connected to the outer side of the adjusting threaded rod 115. An adjusting limit plate 117 is fixedly installed on the top of the adjusting threaded sleeve 116. A clamping bracket 118 is fixedly installed on the top of the adjusting limit plate 117. Horizontal limit plates 118 are symmetrically installed on one side of the clamping bracket 118. 19. A limiting inclined plate 120 is fixedly installed at the end of the horizontal limiting plate 119. A limiting inclined groove 121 is opened at the end of the limiting inclined plate 120. A clamping bolt 122 is threadedly connected to the center of the clamping bracket 118. A clamping spring 123 is rotatably connected to the end of the clamping bolt 122. A clamping friction plate 124 is fixedly installed on one side of the clamping spring 123. A clamping limiting rod 125 is symmetrically installed on the side of the clamping friction plate 124 near the clamping bracket 118. The clamping limiting rod 125 is slidably connected to the clamping bracket 118.

[0023] During the stretching of the rubber sealing ring 126, rotating the adjusting knob 114 drives the adjusting threaded rod 115 to rotate, causing the adjusting threaded sleeve 116 to move the adjusting limiting plate 117, the clamping bracket 118, and the horizontal limiting plate 119. This moves the limiting inclined plate 120 to the outside of the end of the rubber sealing ring 126 without contacting it. The limiting inclined groove 121 can limit the rubber sealing ring 126, effectively preventing it from breaking under tension. The mechanism of the clamping bolt 122 reduces the spring force of the rubber seal 126 upon breakage and rebound, preventing the rubber seal 126 from flying out. By rotating the clamping bolt 122, the clamping spring 123 and the clamping friction plate 124 are moved. The clamping friction plate 124 can rub the surface of the rubber seal 126, thereby testing the friction performance of the rubber seal 126. At the same time, the clamping friction plate 124 can clamp and fix the rubber seal 126, facilitating the measurement of the elongation at break of the rubber seal 126.

[0024] Please see Figures 1-2 , Figure 8 Figure 9The stabilizing tension mechanism 2 includes a detection base 201. A tension motor 207 is fixedly installed at one end of the detection base 201. A tension bidirectional threaded rod 208 is fixedly connected to the output end of the tension motor 207. A tension threaded sleeve 209 is symmetrically threaded to the outer side of the tension bidirectional threaded rod 208. A first tension limiting plate 210 is fixedly installed on the top of the tension threaded sleeve 209. A first support block 211 is fixedly installed on the top of the first tension limiting plate 210. The first support block 211 is fixedly installed at the bottom of the detection chassis 127. A detection scale 206 is fixedly installed on one side of the top of the detection base 201. A pointer 228 is fixedly installed on the outer side of the first tension limiting plate 210, and the pointer 228 points to the detection scale 206.

[0025] Support legs 202 are fixedly installed around the bottom of the testing base 201. Connecting hinges 203 are symmetrically installed on one side of the testing base 201. The two connecting hinges 203 are rotatably connected to the testing protective cover 204. A handle 205 is fixedly installed on the outside of the testing protective cover 204. The connecting hinges 203 and the handle 205 are used to realize the rotation of the testing protective cover 204. When performing tensile testing on the rubber sealing ring 126, the testing protective cover 204 can provide testing protection and improve the safety of the testing. At the same time, the tensile motor 207 is started to drive the tensile bidirectional threaded rod 208 to rotate, so that the tensile threaded sleeves 209 on both sides drive the first tensile limiting plate 210 and the first support block 211 to move relative to each other. Under the sliding action of the tensile sliding rod 212 and the tensile sliding sleeve 213, the two testing bases 127 can move stably, thereby realizing the stable tensile testing of the rubber sealing ring 126. The tensile length of the rubber sealing ring 126 can be measured by the test scale 206 corresponding to the pointer 228 on the outside of the first tensile limiting plate 210.

[0026] Please see Figure 2 , Figures 8-11 A tension sliding rod 212 is fixedly installed on one side of the inner side of the detection base 201. A tension sliding sleeve 213 is symmetrically slidably connected to the outer side of the tension sliding rod 212. A second tension limiting plate 214 is fixedly installed on the top of the tension sliding sleeve 213. A second support block 215 is fixedly installed on the top of the second tension limiting plate 214. A connecting plate 216 is fixedly installed on the top of the second support block 215. One side of the connecting plate 216 is fixedly connected to the detection chassis 127.

[0027] A translational sliding rod 217 is fixedly installed on the side of the test base 201 away from the tension sliding rod 212. A translational sliding sleeve 218 is slidably connected to the outer side of the translational sliding rod 217. A translational sliding plate 219 is fixedly installed on the top of the translational sliding sleeve 218. An electric telescopic rod 220 is fixedly installed on the top of the translational sliding plate 219. A longitudinal support 221 is fixedly installed on the top of the electric telescopic rod 220. A longitudinal motor 222 is fixedly installed at the end of the longitudinal support 221. A longitudinal threaded rod 223 is fixedly connected to the output end of the longitudinal motor 222. A longitudinal threaded sleeve 224 is threadedly connected to the outer side of the longitudinal threaded rod 223. A longitudinal sliding plate 225 is fixedly installed on the top of the longitudinal threaded sleeve 224. An installation sleeve 226 is fixedly installed on one side of the longitudinal sliding plate 225. A marker pen 227 is engaged with the end of the installation sleeve 226.

[0028] By utilizing the sliding connection between the translational sliding rod 217 and the translational sliding sleeve 218, the horizontal movement of the marker pen 227 can be achieved. The height adjustment of the longitudinal support 221 can be achieved using the electric telescopic rod 220. At the same time, the longitudinal motor 222 is started to drive the longitudinal threaded rod 223 to rotate, causing the longitudinal threaded sleeve 224 to drive the longitudinal sliding plate 225 and the mounting sleeve 226 to move longitudinally. The marker pen 227 can be used to mark the surface of the rubber sealing ring 126, which is convenient for measuring the tensile elongation of the rubber sealing ring 126 at different positions. The intelligent pressure detection device 109 is prior art and is not the main technical point of this case. Therefore, this case does not describe the specific structure and detection method of the intelligent pressure detection device 109 in detail.

[0029] Working principle: According to Figures 1-11As shown, firstly, the rubber sealing ring 126 is fitted onto the first drive roller 107 and the second drive roller 112. The limiting rotation groove 108 limits the rubber sealing ring 126 during stretching, ensuring it remains horizontal and improving the accuracy of the stretching test. The connecting hinge 203 and handle 205 enable the rotation of the detection protective cover 204. During the stretching test of the rubber sealing ring 126, the detection protective cover 204 provides protection, enhancing safety. Simultaneously, the stretching motor 207 is activated, driving the stretching bidirectional threaded rod 208 to rotate. This causes the stretching threaded sleeves 209 on both sides to move relative to the first stretching limiting plate 210 and the first support block 211. The stretching sliding rod 212... Under the sliding action of the tension sliding sleeve 213, the two detection chassis 127 can move stably. When the two detection chassis 127 move stably, under the action of the limiting sliding rod 102 and the limiting sliding sleeve 103, the first roller bracket 105 and the second roller bracket 111 can be limited to slide, so that the first roller bracket 105 and the second roller bracket 111 abut against the pressure sensing end of the intelligent pressure detection device 109. By recording the pressure sensed by the tension sensing end, the tension of the rubber sealing ring 126 during the stretching process can be known, thereby realizing the stable stretching detection of the rubber sealing ring 126. The intelligent pressure detection device 109 is equipped with a return spring inside, which can realize the reset of the first roller bracket 105 and the second roller bracket 111 after the detection is completed. Secondly, the stretching length of the rubber sealing ring 126 can be measured by the detection scale 206 corresponding to the pointer 228 on the outside of the first stretching limit plate 210. At the same time, the horizontal movement of the marker pen 227 can be achieved by the sliding connection between the translational sliding rod 217 and the translational sliding sleeve 218. The height of the longitudinal support 221 can be adjusted by the electric telescopic rod 220. At the same time, the longitudinal motor 222 is started to drive the longitudinal threaded rod 223 to rotate, so that the longitudinal threaded sleeve 224 drives the longitudinal sliding plate 225 and the mounting sleeve 226 to move longitudinally. The marker pen 227 can be used to mark the surface of the rubber sealing ring 126, which is convenient for measuring the stretching elongation of the rubber sealing ring 126 at different positions. Finally, the drive motor 106 is started to drive the first drive roller 107 to rotate. Utilizing the characteristic of the rubber sealing ring 126 being closely connected to the first drive roller 107 and the second drive roller 112, the rubber sealing ring 126 is rotated. The rotation allows for the detection of tensile force at different parts of the rubber sealing ring 126. Typically, rotation is paused until the reading of the intelligent pressure detection device 109 stabilizes. This avoids unstable force on the rubber sealing ring 126 due to unidirectional drive during rotation, which would affect the detection accuracy of the intelligent pressure detection device 109. The rotation of the rubber sealing ring 126 allows for tensile testing of different parts of the rubber sealing ring, achieving both tensile testing and uniform stretching. The pressure data obtained from stretching different parts of the rubber sealing ring 126 can be used to determine the material uniformity, vulcanization degree, and formulation rationality of the rubber sealing ring, further improving the accuracy of the test data for the rubber sealing ring 126.

[0030] The beneficial effects of this invention are as follows: 1. By setting a uniform detection mechanism, the rubber sealing ring can be sleeved on the first and second drive rollers. The limiting rotation groove can limit the rubber sealing ring during stretching, ensuring that the rubber sealing ring remains in a horizontal position during stretching, thus improving the accuracy of the stretching test. When the rubber sealing ring is stretched, the first and second roller supports are limited and slid under the action of the limiting sliding rod and the limiting sliding sleeve, so that the first and second roller supports slide until they abut against the pressure sensing end of the intelligent pressure detection device. The intelligent pressure detection device records the tensile force of the rubber sealing ring during stretching. The intelligent pressure detection device is equipped with a return spring, which can reset the first and second roller supports after the test is completed. 2. During the stretching of the rubber seal ring, rotating the adjustment knob drives the adjustment threaded rod to rotate, causing the adjustment threaded sleeve to move the adjustment limit plate, clamping bracket, and horizontal limit plate. The limit inclined plate is moved to the outside of the rubber seal ring end without contacting it. The limit inclined groove effectively limits the rubber seal ring, preventing it from rebounding when it breaks under tension, reducing the spring force, and avoiding the rubber seal ring flying out. This prevents the rapid calculation of the rubber seal ring's tensile strength and elongation at break. Rotating the clamping bolt moves the clamping spring and clamping friction plate, which rubs the surface of the rubber seal ring to test its friction performance and evaluate its ability to resist wear during long-term friction. Key indicators include wear amount, wear depth, and mass / volume loss. The clamping friction plate also clamps and fixes the rubber seal ring, facilitating the measurement of its elongation at break. 3. By setting up a stable tension mechanism, not only can the rotation of the inspection protective cover be achieved using the connecting hinge and handle, but the inspection protective cover can also provide protection during the tensile testing of the rubber seal ring, improving the safety of the test. At the same time, starting the tension motor drives the tension bidirectional threaded rod to rotate, causing the tension threaded sleeves on both sides to move relative to the first tension limiting plate and the first support block. Under the sliding action of the tension sliding rod and the tension sliding sleeve, the two inspection chassis can move stably, thereby achieving stable tensile testing of the rubber seal ring. The tensile length of the rubber seal ring can be measured by the inspection scale corresponding to the pointer on the outside of the first tension limiting plate. At the same time, the horizontal movement of the marker pen can be achieved by the sliding connection between the translation sliding rod and the translation sliding sleeve. The height of the longitudinal support can be adjusted by using the electric telescopic rod. At the same time, starting the longitudinal motor drives the longitudinal threaded rod to rotate, causing the longitudinal threaded sleeve to move the longitudinal sliding plate and the mounting sleeve longitudinally. The surface of the rubber seal ring can be marked with the marker pen, which is convenient for measuring the tensile elongation of different parts of the rubber seal ring.
