Description

Technical Field

[0001] This utility model relates to the field of rubber anticorrosive putty performance testing technology, specifically a rubber anticorrosive putty bonding strength testing device. Background Technology

[0002] Resin mortar, also known as anti-corrosion mortar or rubber anti-corrosion mortar, is a polymer-modified waterproof and anti-corrosion material, mainly used for waterproofing, anti-corrosion, and seepage prevention in building exterior walls, underground engineering, tunnels, and other applications. Its core components include epoxy resin modified latex, chloroprene rubber latex, polyacrylate, and synthetic rubber, manufactured through a composite modification process. The main types include epoxy resin mortar, vinyl ester resin mortar, and polyester resin mortar. The main properties of resin mortar include adhesive strength, compressive strength, corrosion resistance, and water resistance. Adhesive strength is a crucial performance indicator affecting the adhesion of resin mortar; therefore, this application provides a rubber anti-corrosion mortar adhesive strength testing device. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a rubber anti-corrosion putty bonding strength testing device to address the above-mentioned shortcomings.

[0004] To solve the above technical problems, the present invention adopts the following technical solution:

[0005] A device for testing the bonding strength of rubber anti-corrosion putty includes a machine base, an indexing plate, a hexagonal plate, a fixed test head, a hydraulic telescopic cylinder, and a movable test head. The indexing plate is located in the center of the machine base, with its upper surface flush with the upper surface of the machine base. A hexagonal plate is horizontally and coaxially mounted on the indexing plate. A handle is located on the side of the indexing plate; rotating the handle rotates the indexing plate, causing the hexagonal plate to rotate horizontally. Connecting posts perpendicular to the corresponding sides are horizontally arranged radially on the six outer faces of the hexagonal plate. Fixed test heads of different shapes are mounted on multiple connecting posts. A hydraulic telescopic cylinder is mounted on the machine base, with its axis passing through the center of the indexing plate and the hexagonal plate. A connecting head is located at the telescopic end of the hydraulic telescopic cylinder, and a movable test head is detachably mounted on the connecting head. The movable test head and the opposite fixed test head are used to bond the rubber anti-corrosion putty. The hydraulic telescopic cylinder is used to move the movable test head closer to or away from the hexagonal plate.

[0006] Furthermore, the fixed test head on the side of the hexagonal disk has shapes including semi-circular blocks, triangular blocks, trapezoidal blocks, and plate-shaped blocks. The movable test head has various shapes for replacement. The movable test head installed on the hydraulic telescopic cylinder can cooperate with the corresponding fixed test head on the opposite side to form a rectangular block.

[0007] Furthermore, the indexing plate has six outer sides and a fixed plate extending to the top of the machine tool at the edge directly in front of the fixed test head. The fixed plate has a through hole at one end extending to the top of the machine tool, and the machine tool has a corresponding positioning hole directly in front of the hydraulic cylinder. A pin can be inserted through the positioning hole and the through hole to fix the indexing plate relative to the machine tool.

[0008] Furthermore, the active test head and the connector are detachably connected via a square pin.

[0009] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0010] This invention uses fixed test heads of different shapes, such as rectangles, semicircles, trapezoids, and triangles, set on the six outer surfaces of a hexagonal disk to simulate the bonding of rubber anti-corrosion putty under different real-world scenarios, comprehensively evaluate its bonding strength performance, and meet various testing needs.

[0011] A fixed plate is installed on the indexing plate, and its through hole matches the positioning hole of the machine tool with a positioning pin. This can fix the position when the fixed test head and the movable test head are connected, effectively counteracting the axial tension when the hydraulic telescopic cylinder is pulled, ensuring the stability of the test process and improving the accuracy of the test results.

[0012] The fixed test head has a U-shaped indentation on its test surface, while the movable test head has a U-shaped protrusion on its test surface. This structure prevents the anti-corrosion putty from falling off after the two are bonded together. The putty can fill the gap between the fixed and movable test heads, thus more accurately reflecting the bonding strength of the putty.

[0013] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0025] like Figure 1-7 As shown, a rubber anti-corrosion putty bonding strength testing device includes a machine base 1, an indexing plate 2, a hexagonal plate 3, a fixed test head 4, a hydraulic telescopic cylinder 5, and a movable test head 6. The indexing plate 2 is located in the center of the machine base 1, and its upper surface is flush with the upper surface of the machine base 1. The hexagonal plate 3 is horizontally and coaxially mounted on the indexing plate 2. A handle is located on the side of the indexing plate 2; rotating the handle rotates the indexing plate 2, which in turn rotates the hexagonal plate 3 in the horizontal plane. The six outer surfaces of the hexagonal plate 3 are each horizontally arranged radially with corresponding... A vertical connecting column 7 is provided on the side, and fixed test heads 4 of different shapes are respectively provided on the multiple connecting columns 7. A hydraulic telescopic cylinder 5 is provided on the machine base 1. The axis of the hydraulic telescopic cylinder 5 passes through the center of the indexing plate 2 and the hexagonal plate 3. A connecting head 8 is provided at the telescopic end of the hydraulic telescopic cylinder 5. A movable test head 6 is detachably provided on the connecting head 8. Rubber anti-corrosion putty is used to bond the movable test head 6 and the opposite fixed test head 4. The hydraulic telescopic cylinder 5 is used to drive the movable test head 6 to move closer to or away from the hexagonal plate 3.

[0026] In one embodiment, the fixed test head 4 on the side of the hexagonal disk has the shape of a semi-circular block, a triangular block, a trapezoidal block, and a plate-shaped block. The movable test head 6 has various shapes for replacement. The movable test head 6 installed on the hydraulic telescopic cylinder 5 can be joined with the corresponding fixed test head 4 on the opposite side to form a rectangular block.

[0027] In one embodiment, the indexing plate 2 is provided with six outer sides and a fixing plate 9 extending to the top of the machine base 1 at the edge directly in front of the fixed test head 4. The end of the fixing plate 9 extending to the top of the machine base 1 is provided with a through hole. The machine base 1 is provided with a corresponding positioning hole located directly in front of the hydraulic cylinder. A pin can be inserted through the positioning hole and the through hole to fix the indexing plate 2 relative to the machine base 1.

[0028] In one implementation, the active test head 6 and the connector head 8 are detachably connected via a square pin.

[0029] In this utility model, the shape of the fixed test head 4 also includes a corrugated block and a wave block, the hydraulic telescopic cylinder 5 is an axial foot type cylinder, the test surface of the fixed test plate 4 is provided with a U-shaped recess along the edge line, and the test surface of the movable test head 6 is provided with a U-shaped protrusion along the edge line.

[0030] The working process of this utility model is as follows: Select the fixed test head 4 of the required shape according to the test requirements. For example, when it is necessary to test the bonding strength of the putty on a plane, select the plate-shaped fixed test head 4, rotate the indexing plate 2, drive the hexagonal plate 3 to rotate, so that the plate-shaped fixed test head 4 rotates to the position opposite the hydraulic telescopic cylinder 5. The through hole on the indexing plate 2 corresponding to the fixed plate 9 is aligned with the positioning hole on the machine base 1, and the fixed test head 4 is accurately connected with the movable test head 6 on the hydraulic telescopic cylinder 5.

[0031] After the plate-shaped fixed test head 4 is rotated into position, the positioning pin is inserted to fix the position of the hexagonal plate 3 and the fixed test head 4, so as to prevent axial displacement caused by the hydraulic telescopic cylinder 5 during subsequent testing and ensure test stability.

[0032] Select the movable test head 6 that matches the plate-shaped fixed test head 4, and detachably install it onto the connector 8 at the telescopic end of the hydraulic telescopic cylinder 5 using a square pin, ensuring a secure installation.

[0033] Apply rubber anti-corrosion putty evenly to the test surfaces of the fixed test head 4 and the movable test head 6. Then, start the hydraulic telescopic cylinder 5. The hydraulic telescopic cylinder 5 extends and pushes the movable test head 6 toward the fixed test head 4, so that the two are tightly attached and the putty is fully bonded to form a rectangular block of bonded sample. Stop the hydraulic telescopic cylinder 5 and let it stand for a period of time to allow the putty to reach the appropriate bonding strength.

[0034] Start the hydraulic telescopic cylinder 5, causing its telescopic end to slowly retract, applying a pulling force to the movable test head 6. As the pulling force gradually increases, observe the adhesion of the rubber anti-corrosion putty between the fixed test head 4 and the movable test head 6, and record the pulling force value applied by the hydraulic telescopic cylinder 5 when the putty begins to show signs of damage such as cracking or falling off.

[0035] If the adhesion strength of the putty on the curved surface needs to be tested next time, pull out the square pin, remove the movable test head 6 corresponding to the plate-shaped fixed test head 4, replace it with the movable test head 6 corresponding to the semi-circular fixed test plate 4 and fix it with the square pin, then rotate the indexing plate 2 so that the semi-circular fixed test head 4 is rotated to the position opposite the hydraulic telescopic cylinder 5, the through hole on the indexing plate 2 corresponding to the fixed plate 9 is aligned with the positioning hole on the machine base 1, and the fixed test head 4 and the movable test head 6 on the hydraulic telescopic cylinder 5 are accurately connected.

[0036] After the semi-circular fixed test head 4 is rotated into position, insert the positioning pin to fix the position of the hexagonal disk 3 and the fixed test head 4.

[0037] The bonding and testing process for the putty is the same as that for the plate-shaped fixed test head.

[0038] The switching procedure for other shapes of fixed test heads 4 is the same as the procedure described above.

[0039] After the test is completed, the final tensile force data is recorded, which is the bonding strength index of the rubber anti-corrosion putty under this test condition.

[0040] The above description provides examples of the preferred embodiments of this utility model. Any aspects not detailed herein are common knowledge to those skilled in the art. The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
