Description

Technical Field

[0001] The invention relates to the field of glue curing technology, and more specifically, to an experimental device for testing colloid curing. Background Art

[0002] With the adoption of lightweighting technology in the rail transit industry, more and more components are being bonded. To ensure the reliability of the bonding process, the corresponding adhesive process parameters require rigorous measurement. Rail transit window bonding typically uses single-component moisture-curing adhesives. Pre-application testing of their cure rate is essential to accurately determine the post-bonding and transport time of the window, preventing joint failure caused by window movement during vehicle transport. Currently, cure rate data for single-component moisture-curing adhesives used by OEMs is generally provided by the manufacturer. Testing is typically conducted at a temperature of (23±2)°C and a relative humidity of (50±5)%, with a limited number of measurement points, making it of limited reference value for field applications. Field use often involves significantly different temperature and relative humidity conditions than laboratory conditions, particularly in hot summer weather and cold winter weather. Consequently, adhesive cure rates can vary significantly. Manufacturer-provided test data alone is insufficient to meet field production requirements. Users must test the cure rate of adhesives under specific field conditions to ensure effective guidance. However, current single-component moisture-curing adhesives are generally obtained by making a large number of samples and measuring them one by one. There is a lack of a quick, simple and efficient measurement device that can continuously measure multiple curing rate points according to the on-site environment. It can even be used as a vehicle accompanying sample to monitor the curing status of the vehicle's bonding joints in real time. Summary of the Invention

[0033] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0034] Reference Figures 1 to 4 A device for testing colloid curing experiments includes a fixed frame 1, the fixed frame 1 includes a base plate 11, and a partition 12 arranged on the base plate 11, left and right glue limiting plates 13 and 14 are fixedly installed on the base plate 11, the left and right glue limiting plates 13 and 14 are installed close to the partition 12, and the left and right glue limiting plates 13 and 14 and the partition 12 form a glue injection space.

[0035] Reference Figure 5 The partition 12 of this device is divided into two parts, left and right, forming a space between them for the tool self-locking device 5. The base plate 11 is provided with mounting slots 111 for the left and right glue limiting plates 13 and 14. These mounting slots 111 are dovetail grooves, facilitating the installation of the left and right glue limiting plates 13 and 14. When the left and right glue limiting plates 13 and 14 are close to the partition 12, they are fixed to the base plate 11 via fixing bolts. When cleaning after use, the left and right glue limiting plates 13 and 14 can be slid out by loosening the fixing bolts.

[0036] In addition, the left and right glue limiting plates 13 and 14 are inclined plates, so that the glue has different thicknesses after the glue injection space is filled with glue, resulting in different curing times, thereby meeting the needs of subsequent cutting.

[0037] Fixed blocks 2 are provided on both sides of the fixed frame 1. The fixed blocks 2 can be divided into three parts: front, middle and rear. A sliding bar 3 is slidably installed in the fixed block 2. A rubber cutting device 4 is fixedly installed on the sliding bar 3. The rubber cutting device 4 includes a door-shaped bracket 41 fixed on the sliding bar 3. A pressing tool 45 is installed on the column 42 of the door-shaped bracket 41. A compression spring 43 is connected to the column 42. The two ends of the compression spring 43 press against the lower part of the column 42 and the bottom of the pressing tool 45 respectively. The rubber cutting device 4 is divided into two groups, which are respectively located on both sides of the partition 12. In order to make the installation more stable, the door-shaped bracket 41 is fixed to the sliding bar 3 by a support 44. The rubber cutting device 4 can be moved forward and backward relative to the fixed frame 1 by sliding the sliding bar 3. The rubber cutting position of the rubber cutting device 4 can be determined by the scale of the sliding bar 3.

[0038] Reference Figure 3 A tool self-locking device 5 is hingedly installed on the fixed frame 1, and the tool self-locking device 5 includes a turntable 51, and a handle 512 is fixedly installed at the center of the turntable 51. Two cylinders 52 are symmetrically arranged on the turntable 51, and locking blocks 53 are respectively provided at both ends of the turntable 51. A column 54 is provided on each locking block 53, and an arc rod 55 is respectively hingedly installed between the two columns 54 and the two cylinders 52. The two locking blocks 53 are connected by a tension spring 56. The two locking blocks 53 can be pressed on the sliding bar 3 under the push of the arc rod 55 to fix the position of the sliding bar 3; the tension springs 56 are two front and back ones, so that the locking block 53 can be reset more smoothly.

[0039] Reference Figure 7 A fixing block 57 and a spring piece 58 are fixedly installed in the fixing frame 1, and an arc-shaped groove 511 is provided on the side of the turntable 51. A locking bead 59 is placed in the space formed by the arc-shaped groove 511, the spring piece 58 and the fixing block 57. When the turntable 51 rotates clockwise, the locking bead 59 is locked in the space between the arc-shaped groove 511 and the fixing block 57 under the pressure of the spring piece 58.

[0040] Reference Figure 8 A cover plate 6 is installed on the partition 12, and an unlocking rod 7 is installed on the cover plate 6. The lower end of the unlocking rod 7 is a slope 71, and the slope 71 is in contact with the locking bead 59. A spring 72 is installed on the unlocking rod 7, and the two ends of the spring 72 are in contact with the upper surface of the cover plate 6 and the head of the unlocking rod 7 respectively.

[0041] The working principle of the present invention is as follows: During the experiment, glue is injected into the glue injection space formed by the left and right glue injection limiting plates 13 and 14 and the partition 12, and then cooled. Because the left and right glue injection limiting plates 13 and 14 are inclined panels, the glue thickness varies after the glue injection space is filled, resulting in different curing times. The sliding bar 3 can be used to move the glue cutting device 4 forward and backward relative to the fixed frame 1, and the scale of the sliding bar 3 can be used to determine the position of the glue cutting device 4. This experimental device can continuously measure multiple curing rate points, which is quick, simple and efficient.

[0042] When the rubber cutting device 4 moves to the corresponding position, the tool self-locking device 5 is required to lock the rubber cutting device 4 from moving forward or backward. Specifically, after the rubber cutting device 4 moves to the rubber cutting position, the handle 512 is rotated counterclockwise. The turntable 51 pushes the locking block 53 against the sliding bar 3 via the arc-shaped rod 55, thereby fixing the sliding bar 3 in place. When the handle 512 is released, the locking bead 59, under the pressure of the spring 58, locks in the space between the arc-shaped groove 511 and the fixing block 57, thereby preventing the rubber cutting device 4 from moving forward or backward relative to the frame when the handle 512 is released.

[0043] A cover plate 6 is installed on the partition 12, and an unlocking rod 7 is installed on the cover plate 6. The lower end of the unlocking rod 7 is a slope 71, and the slope 71 is in contact with the locking bead 59. A spring 72 is installed on the unlocking rod 7, and the two ends of the spring 72 are in contact with the upper surface of the cover plate 6 and the head of the unlocking rod 7 respectively.

[0044] When cutting rubber, the pressing tool 45 is pressed, and the pressing tool 45 moves downward along the column 42 of the gate-shaped bracket 41 to cut the rubber. After the rubber is cut, the compression spring 43 automatically resets the rubber. In addition, when the unlocking lever 7 is pressed, the lower end of the inclined surface 71 impacts the locking bead 59, thereby allowing the turntable 51 to rotate clockwise. Under the action of the tension spring 56, the turntable 51 rotates clockwise, and the locking block 53 automatically resets.

[0045] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solution that can be derived by those skilled in the art through logical analysis, reasoning, or limited experimentation based on the concepts of the present invention and the prior art should be within the scope of protection defined by the claims.
