Description

Technical Field

[0001] This utility model belongs to the field of liquefied natural gas and relates to the vertical tensile performance testing technology of adhesives, specifically to a tooling for preparing adhesive vertical tensile performance test samples. Background Technology

[0002] LNG (liquefied natural gas) ships are vessels specifically designed for the storage and transportation of liquefied natural gas. They store liquefied natural gas in storage tanks, which are constructed by assembling various modules (such as insulating blocks and shielding blocks) in two stages. The modules are bonded and fixed together using adhesives. Due to the special properties of liquefied natural gas, the requirements for the sealing and connection strength between the modules are very high. Therefore, it is necessary to conduct vertical tensile performance tests on the adhesives used to ensure that the adhesives meet the performance standards.

[0003] Existing methods for testing vertical tensile properties involve bonding two test modules of a specified structure together with an adhesive to form a test sample, which is then connected to a testing machine to test the adhesive's vertical tensile properties. During the bonding process, the two test modules need to be pressed together to cure the adhesive. However, in actual pressing, the two test modules are difficult to fix and position effectively, the accuracy of their mating position cannot be guaranteed, and relative sliding between the modules is prone to occur, leading to positional shifts and affecting the accuracy of the final vertical tensile property test. Summary of the Invention

[0004] Purpose of the invention: In order to overcome the shortcomings of the existing technology, a tooling for preparing test samples for the vertical tensile properties of adhesives is provided. This tooling can effectively fix and position the test sample, ensuring the relative positional accuracy and precision of the two test modules in the test sample, and thus guaranteeing the accuracy of subsequent vertical tensile property tests.

[0005] Technical Solution: To achieve the above objectives, this utility model provides a tooling for preparing a test sample for the vertical tensile properties of adhesives, including a base plate and a plurality of positioning strips evenly arranged on the base plate. Adjacent positioning strips form positioning grooves on the base plate. An mounting plate and a limiting plate are respectively provided on both sides of the base plate. A plurality of lifting cylinders are provided on the mounting plate. A pushing block is provided on the lifting rod of the lifting cylinder. The pushing block corresponds one-to-one with the positioning groove. The positioning groove matches the test sample. The pushing block is used to push the test sample. The limiting plate is used to limit the test sample.

[0006] Furthermore, a 7-shaped positioning block is provided on the base plate at the positioning groove, and the 7-shaped positioning block is used to limit the side and top of the test sample.

[0007] Furthermore, the lifting cylinder includes an actuator and an air inlet, the air inlet being used to supply air to the actuator, and the actuator being used to push the lifting rod.

[0008] Furthermore, the air intake is equipped with air supply branch pipes, and all air supply branch pipes are connected to the main air supply pipe.

[0009] Furthermore, a limit block is provided on the positioning strip located on the side of the base plate.

[0017] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0018] like Figure 1 and Figure 2As shown, this utility model provides a tooling for preparing samples for testing the vertical tensile properties of adhesives. It includes a base plate 1 and 11 positioning strips 2 arranged at equal intervals on the base plate 1. Adjacent positioning strips 2 form positioning grooves 3 on the base plate 1. In this embodiment, the number of positioning grooves 3 is 10. Mounting plates 5 and limiting plates 4 are respectively provided on both sides of the base plate 1. Ten lifting cylinders are provided on the mounting plate 5. Each lifting cylinder includes an actuator 7 and an air inlet 10. A lifting rod 8 is provided on the actuator 7, and a pushing block 9 is provided on the lifting rod 8. The actuator 7 and the air inlet 10 are mounted on the mounting plate 5. The 10 pushing blocks 9 correspond one-to-one with the 10 positioning grooves 3. The air inlet 10 supplies air to the actuator 7, which in turn pushes the lifting rod 8. A gas supply branch pipe 11 is provided, and all gas supply branch pipes 11 are connected to the gas supply main pipe 12. The positioning groove 3 matches the test sample 100. A 7-shaped positioning block 13 is provided on the base plate 1 at the positioning groove 3. The 7-shaped positioning block 13 is used to limit the side and top of the test sample 100. A limit block 6 is provided on the positioning strip 2 on the side of the base plate 1. A slot 15 matching the 7-shaped positioning block 13 is provided on the positioning strip 2. The 7-shaped positioning block 13 is snapped and fixed on the slot 15. Bolt fasteners 14 are provided on the positioning strip 2 on the two sides of the base plate 1. The bolt fasteners 14 are used to fix the 7-shaped positioning block 2 on the side. The pushing block 9 is used to push the test sample 100. The limit plate 4 is used to limit the test sample 100.

[0019] In this embodiment, the above-mentioned preparation fixture is used for the pressing preparation of test sample 100. Test sample 100 consists of two test modules 101. The specific pressing preparation process is as follows:

[0020] First, apply adhesive to the mating surfaces of the two test modules 101. Then, place the two test modules 101 sequentially into the positioning groove 3. Next, insert the L-shaped positioning blocks 13 in the middle into the corresponding slots 15, ensuring a tight fit between the L-shaped positioning blocks 13 and the adjacent test modules 101 for fixation. The L-shaped positioning blocks 2 on the sides are tightened and fixed using bolts 14. Under the action of the positioning groove 3 and the L-shaped positioning blocks 13, the two test modules 101 can accurately align. Then, activate the lifting cylinder, using the lifting rod 8... Push the pressing block 9 toward the test module 101. After the pressing block 9 contacts the test module 101, it continues to push the two test modules 101. Under the limiting action of the limiting plate 4, the two test modules 101 continue to be pressed together. During this process, due to the role of the positioning groove 3 and the 7-shaped positioning block 13, the relative position of the two test modules 101 will not shift. After the pressing time is reached, the test sample 100 is formed. Close the lifting cylinder, retract the pressing block 9, and remove all the 7-shaped positioning blocks 13. Finally, remove the test sample 100.

[0021] The extracted test sample 100 can be used for vertical tensile property testing of adhesives.
