Description

Technical Field

[0001] The invention relates to the field of test technology, and in particular to a rubber sealing strip tensile test device capable of simulating different temperature environments. Background Art

[0002] Rubber sealing strips are strip-shaped rubber sealing products, mostly used in railway locomotives, automobiles, airplanes, high-rise buildings, refrigerators and various industrial parts. After the rubber sealing strips are processed and produced, in order to know the durability of the rubber sealing strips, it is necessary to use a tensile test device to perform tensile testing on the rubber sealing strips.

[0003] During use of the existing rubber sealing strip tensile test device, in order to know the strength of the sealing strip at different temperatures, the sealing strip is usually placed in a temperature-adjustable sealing chamber for tensile test. However, after the high-temperature test on the sealing strip in the sealing chamber, the staff needs to put their hands into the sealing chamber to take out the sealing strip after the tensile test.

[0031] Please refer to Figures 1 to 10 :

[0032] Embodiment 1:

[0034] By placing the sealing strip 27 to be tested inside the clamping portion 26 in the pop-up state, and then rotating the opening and closing screw rod 6 counterclockwise, the opening and closing screw rod 6 moves the opening and closing slide plate 8 and the opening and closing slide post 9 backward, so that the opening and closing slide post 9 on the opening and closing slide plate 8 slides from the limiting groove 4 into the opening and closing inclined groove 3, and the inclined structure of the opening and closing inclined groove 3 drives the two sealing slide frames 2 to dock, so that the two sealing slide frames 2 seal the test body 1, and in the process of the opening and closing slide block 7 moving backward, the opening and closing slide post 9 will cancel the push on the front end of the transition groove 21, so that the disengagement slide plate 20 and the disengagement slide rail 22 are under the action of the spring C36. The stretching slider 25 and the sealing strip 27 to be tested are moved backward with the stretching slider 25 and the sealing strip 27 to be tested, so that the stretching slider 25 and the sealing strip 27 to be tested slide into the test body 1 to wait for the stretching test before the sealing slide frame 2 is docked and closed. When the stretching slider 25 moves backward and is stored in the interior of the test body 1, the driven column 30 slides from the interior of the lifting groove 18 into the interior of the holding groove 17, so that the driven column 30 utilizes the inclined structure of the lifting groove 18 to convert the backward movement force into a downward pressure and provides it to the holding piece 28. At the same time, the connecting column 35 also slides into the interior of the retaining groove 19, so that the holding piece 28 can realize the compression and positioning of the sealing strip 27 to be tested by moving downward.

[0035] Embodiment 2, on the basis of embodiment 1, the left end of the connecting pipe 14 is connected to the external heating pipeline; a plurality of heating pipes 15 are fixedly installed on the top of the connecting pipe 14; the top of the heating pipe 15 is inserted into the interior of the test body 1; a transmission plate 16 is fixedly installed on the bottom end of the interior of the test body 1 in a bilaterally symmetrical arrangement; a holding groove 17 is provided on the outer side of the transmission plate 16; a lifting groove 18 with an inclined structure is provided on the outer front end of the transmission plate 16; the bottom end of the lifting groove 18 is connected to the front end of the holding groove 17; two lifting grooves are also provided on the rear side of the interior of the test body 1 Retaining groove 19; a disengagement slide 20 is slidably installed on the left and right sides of the interior of the test body 1; a transition groove 21 is provided at the outer rear end of the disengagement slide 20; the inner end of the opening and closing slider 7 is also slidably installed inside the transition groove 21; a disengagement slide rail 22 is fixedly installed between the two disengagement slides 20; a clamping groove 23 is provided at the bottom of the disengagement slide rail 22; a conversion groove 24 with an inclined structure is also provided at the bottom of the disengagement slide rail 22; the inner end of the clamping groove 23 at the rear end of the conversion groove 24 is connected; one end of a spring C36 is embedded in the rear side of the disengagement slide rail 22.

[0036] After the stretching slider 25 and the sealing strip 27 to be tested are received into the interior of the test body 1, the driving motor 5 is started so that the driving motor 5 rotates with the stretching screw 11 under the action of the sprocket and the chain, so that the stretching screw 11 rotates with the two stretching sliders 25 and the connecting slide 13 to slide relatively outward along the two stretching slide grooves 10. During the sliding process, since the connecting slide 13 is also slidably connected to the stretching slider 25, the connecting slide 13 will provide an outward movement force to the stretching slider 25, so that the stretching slider 25 moves outward with the clamping portion 26 and the outer end of the sealing strip 27 to be tested, and a tensile test is performed on the sealing strip 27 to be tested. At the same time, the clamping slide column 32 will slide from the interior of the conversion groove 24 into the interior of the clamping groove 23, so that the clamping slide column 32 uses the inclined structure of the conversion groove 24 to move the clamping slide 31 and the clamping member 34 backward, so that the clamping member 34 can achieve further clamping of the two ends of the sealing strip 27 to be tested by moving backward, thereby improving the stability of the sealing strip 27 to be tested during the tensile test.

[0037] Embodiment 3, on the basis of embodiment 2, the other end of the spring C36 is embedded and installed on the inner rear side wall of the test body 1; a stretching slider 25 is slidably installed on the disengagement slide rail 22; a clamping portion 26 is fixedly installed on the front side of the stretching slider 25; the stretching slider 25 is also slidably connected to the connecting slide 13; a sealing strip 27 to be tested is also clamped on the clamping portion 26; a pressing member 28 is also slidably installed on the stretching slider 25; one end of the spring A29 is embedded and installed on the inner top of the pressing member 28; the other end of the spring A29 is embedded and installed on the top of the stretching slider 25; a driven column 30 of a cylindrical structure is fixedly installed on the bottom of the pressing member 28; the stretching slider 25 is in a non-stretched state In the state, the driven column 30 can be slidably installed inside the pressing groove 17 and the lifting groove 18; the front side of the stretching slider 25 is slidably installed with an L-shaped clamping slide plate 31; the top rear end of the clamping slide plate 31 is fixedly installed with a clamping slide column 32 with a cylindrical structure; one end of the spring B33 is embedded in the clamping slide plate 31; the other end of the spring B33 is embedded in the front side of the clamping portion 26; the clamping member 34 is also fixedly installed on the clamping slide plate 31; the clamping member 34 is also slidably installed on the clamping portion 26; the rear side of the driven column 30 is fixedly installed with a connecting column 35; when the detached slide rail 22 is stored inside the test body 1, the connecting column 35 should be slidably installed inside the retaining groove 19.

[0038] After the tensile test is completed, the driving motor 5 is reversed so that it can restore with the tensile slider 25 under the action of the tensile screw rod 11, so that the inner end of the driven column 30 slides into the interior of the pressure holding groove 17. At this time, the clamping slide 32 will also slide into the front end of the conversion groove 24, so that the clamping slide 31 and the clamping member 34 cancel the clamping of the sealing strip by moving forward, and then the opening and closing screw rod 6 is rotated clockwise to move forward with the opening and closing slider 7, the opening and closing slide 8 and the opening and closing slide column 9. At this time, the inner end of the opening and closing slide column 9 will temporarily slide inside the transition groove 21. At the same time, the opening and closing slide column 9 will preferentially use the inclined structure of the opening and closing inclined groove 3 to move the two sealing slide frames 2 up and down relative to each other, and open the sealing slide frame 2. In the process of the opening and closing slide block 7 continuing to move forward, the opening The closing slide column 9 will slide along the limiting groove 4 to keep the sealing slide frame 2 in the open state. At the same time, the opening and closing slide block 7 will push the front end of the transition groove 21, so that the transition groove 21 is forced to move forward with the disengagement slide plate 20, the disengagement slide rail 22 and the stretching slide block 25, so that the tested sealing strip on the stretching slide block 25 slides out from the inside of the test body 1. During the sliding out process, the driven column 30 will also slide from the inside of the holding groove 17 into the inside of the lifting groove 18, so that the driven column 30 uses the inclined structure of the lifting groove 18 to lift the holding piece 28, so that the holding piece 28 no longer presses the sealing strip tightly. In this way, the limitation on the sealing strip is completely cancelled, which is convenient for canceling the tested sealing strip and placing the sealing strip 27 to be tested on the clamping part 26 for testing.

[0039] Working principle:

[0040] During the tensile test, the sealing strip 27 to be tested is placed inside the clamping portion 26 in the pop-up state, and then the opening and closing screw rod 6 is rotated counterclockwise to move the opening and closing screw rod 6 with the opening and closing slide plate 8 and the opening and closing slide column 9 backward, so that the opening and closing slide column 9 on the opening and closing slide plate 8 slides from the limiting groove 4 into the interior of the opening and closing inclined groove 3, and the inclined structure of the opening and closing inclined groove 3 is used to drive the two sealing slide frames 2 to dock, so that the two sealing slide frames 2 seal the test body 1, and in the process of the opening and closing slide block 7 moving backward, the opening and closing slide column 9 will cancel the push on the front end of the transition groove 21, so that the disengagement slide plate 20 and the disengagement slide rail 22 move backward with the tensile slide block 25 and the sealing strip 27 to be tested under the action of the spring C36, so that the tensile slide block 25 and the sealing strip 27 to be tested are 27 slides into the test body 1 before the sealing slide frame 2 is docked and closed to wait for the tensile test, and when the tensile slider 25 moves backward and is stored in the interior of the test body 1, the driven column 30 slides from the inside of the lifting groove 18 into the inside of the pressure holding groove 17, so that the driven column 30 uses the inclined structure of the lifting groove 18 to convert the backward movement force into a downward force to provide it to the pressure holding member 28, and at the same time, the connecting column 35 also slides into the inside of the holding groove 19, so that the pressure holding member 28 can realize the compression and positioning of the sealing strip 27 to be tested by moving downward. After the tensile slider 25 and the sealing strip 27 to be tested are stored in the interior of the test body 1, the hot air is transported into the interior of the test body 1 through the external heating pipeline using the connecting pipe 14 and the heating pipe 15, so as to adjust the temperature inside the test body 1 The modification is convenient for simulating the tensile strength of the sealing strip 27 to be tested under different temperature environments. After the temperature reaches the requirement, the driving motor 5 is started to rotate the stretching screw rod 11 under the action of the corresponding sprocket and chain, so that the stretching screw rod 11 rotates with the two stretching sliders 25 and the connecting slider 13 along the two stretching slide grooves 10 to slide relatively outward. During the sliding process, since the connecting slider 13 is also slidably connected to the stretching slider 25, the connecting slider 13 will provide an outward movement force to the stretching slider 25, so that the stretching slider 25 moves outward with the clamping portion 26 and the outer end of the sealing strip 27 to be tested, and a tensile test is performed on the sealing strip 27 to be tested. At the same time, the clamping slide column 32 will slide from the inside of the conversion groove 24 into the inside of the clamping groove 23, so that The clamping slide column 32 uses the inclined structure of the conversion groove 24 to move the clamping slide plate 31 and the clamping member 34 backward, so that the clamping member 34 can further clamp the two ends of the sealing strip 27 to be tested by moving backward, thereby improving the stability of the sealing strip 27 to be tested during the tensile test. After the tensile test is completed, the driving motor 5 is reversed to restore the stretching slide block 25 under the action of the stretching screw rod 11, so that the inner end of the driven column 30 slides into the interior of the pressure holding groove 17. At this time, the clamping slide column 32 will also slide into the front end of the conversion groove 24, so that the clamping slide plate 31 and the clamping member 34 cancel the clamping of the sealing strip by moving forward, and then the opening and closing screw rod 6 is rotated clockwise to move forward with the opening and closing slide block 7, the opening and closing slide plate 8 and the opening and closing slide column 9.At this time, the inner end of the opening and closing slide post 9 will temporarily slide inside the transition groove 21, and at the same time, the opening and closing slide post 9 will preferentially use the inclined structure of the opening and closing inclined groove 3 to move the two sealing slide frames 2 up and down relative to each other, so that the sealing slide frame 2 is opened, so that when the opening and closing slider 7 continues to move forward, the opening and closing slide post 9 will slide along the limiting groove 4 to keep the sealing slide frame 2 in the open state, and at the same time, the opening and closing slider 7 will push the front end of the transition groove 21, so that the transition groove 21 is forced to drive the detachment slide plate 20, the detachment slide rail 22 and the stretching slider 25 moves forward, so that the tested sealing strip on the stretching slide block 25 slides out from the inside of the test body 1. During the sliding out process, the driven column 30 also slides from the inside of the pressing groove 17 into the inside of the lifting groove 18, so that the driven column 30 uses the inclined structure of the lifting groove 18 to lift the pressing member 28, so that the pressing member 28 no longer presses the sealing strip tightly, so that the limitation on the sealing strip is completely eliminated, which is convenient for removing the tested sealing strip and placing the sealing strip 27 to be tested on the clamping part 26 for testing.
