Description

Technical Field

[0001] This utility model belongs to the field of testing equipment, and specifically relates to a device for testing the dynamic explosion resistance of polymer elastomer materials. Background Technology

[0002] The dynamic explosion resistance testing device for polymer elastomer materials is used to evaluate the dynamic mechanical response and explosion resistance of polymer elastomer materials under explosive loads. Current dynamic explosion resistance testing devices for polymer elastomer materials have weaknesses in responding to the hazards of explosions. The high-intensity impact generated by an explosion can easily injure users standing outside the equipment. This is mainly due to the device's initial design not accurately predicting the propagation path and damage range of the explosion impact, and lacking corresponding buffering mechanisms. To reduce impact hazards, the conventional approach is to add cushioning materials, such as rubber pads, around critical components. However, rubber pads are prone to aging and loss of elasticity under long-term high-impact environments, significantly reducing their cushioning effect. Therefore, a new structure is needed to address the aforementioned technical problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a dynamic explosion-proof performance testing device for polymer elastomer materials, thereby solving the problems mentioned in the background section.

[0004] This utility model is achieved through the following technical solution: a dynamic explosion-proof performance testing device for polymer elastomer materials, comprising: a base assembly, an explosion assembly, and a clamping assembly. The upper surface of the base assembly is fixed with a shell assembly for shielding by screws. The upper surface of the base assembly is equipped with an explosion assembly for conducting explosion tests on polymer elastomer materials. The upper surface of the base assembly is equipped with a clamping assembly for clamping and fixing the polymer elastomer materials. The explosion assembly includes a fixing frame and an explosion cylinder. The explosion cylinder is mounted on the upper surface of the base assembly through the fixing frame.

[0005] In a preferred embodiment, the base assembly includes a base body, buffer feet, a first connecting seat, and a second connecting seat. A buffer foot is installed at each of the four corners of the lower surface of the base body. The first connecting seat is installed on the upper surface of the base body, and the second connecting seat is installed on the upper surface of the first connecting seat. The upper surfaces of the first connecting seat and the second connecting seat are recessed downward to form grooves.

[0006] In a preferred embodiment, the fixing frame has a U-shaped structure and is made of high-strength ribs. An explosive tube is installed at the center of the lower surface of the fixing frame through the high-strength ribs. The lower surface of the explosive tube has an opening design, and the opening of the explosive tube is aligned with the groove.

[0007] In a preferred embodiment, the clamping assembly includes a fixing plate, a threaded rod, and a clamping plate. A fixing plate is installed on the left and right edges of the upper surface of the base assembly, and the fixing plate is installed on the edge of the groove.

[0008] In a preferred embodiment, two threaded rods are symmetrically installed through the upper surface of the fixing plate. A knob is installed at the upper end of the threaded rod, and a clamping plate is rotatably installed at the lower end of the threaded rod.

The materials of the outer shell assembly and the base assembly match the materials of the mounting bracket. An installation plate is integrally formed on the outer edge of the lower surface of the outer shell body. The outer shell body is installed on the upper surface of the base assembly via the installation plate. In use, the outer shell assembly is fixed to the upper surface of the base assembly with screws. During testing, it can effectively shield against dangerous factors such as flying fragments and shock waves generated during the explosion test, providing a safety barrier for operators and surrounding equipment.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting a clamping component, an explosion component for conducting explosion tests on polymer elastomer materials is installed on the upper surface of the base component, and a clamping component for clamping and fixing the polymer elastomer materials is installed on the upper surface of the base component.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 3As the first embodiment of this utility model: a dynamic explosion resistance test device for polymer elastomer materials, including: a base assembly, an explosion assembly and a clamping assembly. The upper surface of the base assembly is fixed with a shell assembly for shielding by screws. The upper surface of the base assembly is equipped with an explosion assembly for conducting explosion tests on polymer elastomer materials. The upper surface of the base assembly is equipped with a clamping assembly for clamping and fixing polymer elastomer materials. The explosion assembly includes a fixing frame 300 and an explosion cylinder 310. The explosion cylinder 310 is installed on the upper surface of the base assembly through the fixing frame 300.

[0023] The base assembly includes a base body 100, buffer feet 130, connecting seat one 110 and connecting seat two 120. A buffer foot 130 is installed at each of the four corners of the lower surface of the base body 100. A connecting seat one 110 is installed on the upper surface of the base body 100. A connecting seat two 120 is installed on the upper surface of the connecting seat one 110. The upper surfaces of the connecting seat one 110 and the connecting seat two 120 are recessed downward to form grooves.

[0024] The fixing frame 300 has a U-shaped structure and is made of high-strength ribs. An explosive tube 310 is installed at the center of the lower surface of the fixing frame 300 through the high-strength ribs. The lower surface of the explosive tube 310 has an open design, and the opening of the explosive tube 310 is aligned with the groove.

[0025] The clamping assembly includes a fixing plate 200, a threaded rod, and a clamping plate 220. A fixing plate 200 is installed on the left and right edges of the upper surface of the base assembly, and the fixing plate 200 is installed on the edge of the groove.

[0026] Two threaded rods are symmetrically installed through the upper surface of the fixing plate 200. A knob 210 is installed at the upper end of the threaded rod, and a clamping plate 220 is rotatably installed at the lower end of the threaded rod. The lower surface of the clamping plate 220 abuts against the bottom of the groove through the threaded rod.

[0027] When using this device, the user first needs to prepare the high-polymer elastomer material for the explosion-resistant test. Then, the wireless sensor used for the test is bonded to the non-contact explosion-resistant surface of the high-polymer elastomer material, allowing the explosion test data to be viewed via an external computer (the sensor and connection circuit mentioned above are existing technologies, and their specific working principles and structures are not detailed here). After setting up, the user can place the high-polymer elastomer material inside the groove, and then place both sides of the high-polymer elastomer material below the fixing plates 200 on both sides. The user can then rotate the threaded rod using the knob 210, causing the threaded rod to move the clamping plate 220 downwards. The clamping plate 220 then clamps and fixes the high-polymer elastomer material below the fixing plate 200. After clamping and fixing the high-polymer elastomer material, the user can then proceed with the test. Prepare the explosives (the explosives are existing technology; their specific components, content, and detonation requirements need to be handled and prepared by professionals under actual use conditions, and will not be elaborated here). After installing the explosives inside the explosive cartridge 310, the user can then install the outer casing assembly. The user can then detonate the explosives inside the cartridge, causing the explosives to explode. The shock wave will then be discharged along the opening of the explosive cartridge 310, impacting the polymer elastomer material and thus testing its blast resistance. During use, by integrating the clamping assembly and the explosive assembly onto the base assembly, the dynamic blast resistance test of the polymer elastomer material can achieve integrated operation of stable material clamping and precise application of explosive load. This avoids deviations caused by material displacement during the test, ensuring the accuracy and reliability of the test data.

[0028] Please see Figures 1 to 3 As a second embodiment of the present utility model: based on the description in the above embodiments, further, the inner surface of the clamping plate 220 abuts against the inner surface of the fixing plate 200, and the outer shell assembly includes an outer shell body 400, a handle 430, an observation window 420 and a mounting plate 410, and the front surface of the outer shell body 400 is equipped with an observation window 420 made of explosion-proof glass.

[0029] A handle 430 is installed on the left and right surfaces of the outer shell body 400 respectively. The materials of the outer shell assembly and the base assembly are matched with the material of the fixing frame 300. A mounting plate 410 is integrally formed on the outer edge of the lower surface of the outer shell body 400. The outer shell body 400 is mounted on the upper surface of the base assembly through the mounting plate 410.

[0030] In use, after the polymer elastomer material has been clamped and fixed through the operation steps of the first embodiment, and an anti-explosion test is required, the user can lift the outer shell 400 to the top of the base assembly using the handle 430. Then, the explosive assembly on the top of the base assembly is placed inside the outer shell 400, so that the outer shell 400 is fixed to the upper surface of the base assembly by the mounting plate 410. After the outer shell assembly is fixed, the user can detonate it through the operation steps of the first embodiment, and then conduct an anti-explosion performance test on the polymer elastomer material. Since the outer shell assembly is fixed to the upper surface of the base assembly with screws during use, it can effectively shield dangerous factors such as flying fragments and shock waves generated during the explosion test, providing a safety protection barrier for operators and surrounding equipment.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
