Description

Technical Field

[0001] This utility model relates to the field of fire door testing technology, specifically a pressure testing device for fire door production and processing. Background Technology

[0002] In the production and processing of fire doors, pressure testing is a crucial step to ensure their performance meets standards and guarantees safe use. As an important facility for fire-resistant partitioning in buildings, fire doors need to have sufficient compressive strength to withstand the impact force and high-temperature deformation pressure during a fire. Therefore, they must undergo rigorous pressure testing before leaving the factory.

[0003] Existing fire door pressure testing equipment has many shortcomings in practical applications. In the pre-test loading stage, it mostly relies on manual handling or simple mechanical assistance, which is not only labor-intensive but also makes it difficult to ensure the fire door is placed accurately and stably in the test position. Placement deviations can easily affect the accuracy of test results. The test platform, as the core load-bearing component of the equipment, inevitably suffers wear or failure after long-term use. Traditional equipment often uses a fixed connection for the platform, making disassembly and maintenance cumbersome and time-consuming, severely impacting the continuity and efficiency of testing. The clamping mechanism is mostly unidirectional or manually adjustable, making it difficult to adapt to fire doors of different sizes and specifications. Uneven clamping force can also cause the fire door to shift during testing, affecting the reliability of pressure test data. After testing, the transfer of fire doors usually requires additional equipment or manual intervention, failing to form a continuous automated operation with the testing process. Overall testing efficiency is low and cannot meet the needs of modern mass production. Summary of the Invention

A pair of second threaded rods 20 are fixedly connected to the output ends of the pair of bidirectional drive motors 19 on the front and rear sides. The outer wall of the pair of second threaded rods 20 is threaded. The device has a pair of connecting rings 21, a pair of fixing rods 22 fixedly connected to one side of the pair of connecting rings 21, and a movable plate 23 fixedly connected to one side of the pair of fixing rods 22. The movable plate 23 is located inside the first groove 17, and a pair of mounting blocks 24 are fixedly connected to the upper surface of the pair of movable plates 23. The second threaded rod 20 is rotated by the first bidirectional drive motor 19, so that the connecting rings 21 and the second threaded rod 20 are threadedly driven. The connecting rings 21 and the fixing rods 22 are connected to each other, so that the movable plate 23 moves back and forth, thereby driving the mounting blocks 24 and the clamping plate 25 to move, thereby clamping the material.

[0022] Preferred, such as Figure 3As shown, the transport mechanism includes a clamping plate 25, a mounting groove 26, a second drive motor 27, a rotating shaft 28, and a conveyor belt 29. The transport mechanism includes a clamping plate 25 fixedly connected to the upper surface of the mounting block 24. A pair of clamping plates 25 are fixedly connected to the upper surface of a pair of mounting blocks 24. Each pair of clamping plates 25 has a mounting groove 26 inside. A second drive motor 27 is fixedly connected to the right side of the upper surface of the pair of clamping plates 25. A rotating shaft 28 is fixedly connected to the output end of the lower surface of the second drive motor 27. A conveyor belt 29 is driven to the outer wall of the rotating shaft 28. The rotating shaft 28 is located inside the mounting groove 26. The outer wall of the rotating shaft 28 is driven to the outer wall of the rotating shaft 28. While the clamping plate 25 moves the plate 23, it clamps the material. After the test, the second drive motor 27 drives the rotating shaft 28 to rotate, thereby driving the conveyor belt 29 to rotate, so that the material is removed from the placement table 32, thereby unloading the material.

[0023] Preferred, such as Figure 1 As shown, adjustable support bases 2 are movably connected to both the front and rear sides of the mounting bracket 1. A hydraulic rod 30 is fixedly connected to the lower surface of the hydraulic tank 3. A hydraulic plate 31 is fixedly connected to the output end of the lower surface of the hydraulic rod 30. The hydraulic tank 3 controls the extension and retraction of the hydraulic rod 30, thereby driving the hydraulic plate 31 to perform pressure testing on the material on the placement platform 32, thereby detecting the quality of the material.

[0024] In use, firstly, during the loading stage, the fire door to be tested is placed on the lifting plate 8, and the first drive motor 6 is started. Its output end drives the first threaded rod 7 to rotate. Under the limiting action of the guide groove 5, the lifting plate 8 is smoothly lifted and lowered along the mounting frame 4 to the height of the placement platform 32. Then, the telescopic rod 10 extends and pushes the pusher plate 11 to smoothly push the fire door on the lifting plate 8 into the placement platform 32, thus completing the automatic loading. Next, during the clamping and fixing stage, after the fire door is placed in place, the bidirectional drive motor 19 starts, driving the second threaded rod 20 to rotate, causing the connecting ring 21 threaded on the second threaded rod 20 to move towards each other along the rod body. The connecting ring 21 drives the moving plate 23 to move synchronously in the first groove 17 through the fixing rod 22, thereby causing the clamping plate 25 on the mounting block 24 to move closer to the center, firmly clamping the fire door and ensuring that no displacement occurs during the test. Then, during the pressure test phase, after clamping is completed, the hydraulic tank 3 controls the hydraulic rod 30 to extend downward, driving the hydraulic plate 31 to slowly press against the surface of the fire door. The preset pressure is applied through the hydraulic system to test the pressure resistance of the fire door. During the test, the pressure data and the deformation of the fire door can be recorded through relevant detection elements. Finally, during the material unloading and transportation phase, after the test is completed, the hydraulic rod 30 drives the hydraulic plate 31 to reset, and the bidirectional drive motor 19 rotates in the opposite direction to make the clamping plate 25 release the fire door. Subsequently, the second drive motor 27 starts, drives the rotating shaft 28 to rotate, and makes the conveyor belt 29 run, transporting the fire door on the placement table 32 out of the test area, thus completing the entire test process.
