Description

Technical Field

[0001] This utility model relates to the field of coil tensile testing technology, and in particular to a coil tensile testing device. Background Technology

[0002] A roll material tensile testing device is a device used to test the tensile properties of roll materials (such as waterproof rolls, polymer rolls, etc.). Its core function is to apply tensile force to the roll sample to simulate the tensile action of the material in actual application scenarios, and then measure and analyze the key mechanical properties of the material such as tensile strength, elongation at break, and yield strength. This provides a scientific basis for evaluating the quality of roll materials, designing material selection and optimizing processes, and is widely used in the material performance testing process in the building materials and other fields.

[0003] When performing tensile tests on rolled materials, the two ends of the sample need to be clamped and positioned using fixtures. Stretching can be applied to the sample when the two fixtures are far apart. Some rolled materials have high flexibility, so toothed fixtures can be used to prevent the material from sliding relative to the fixtures; other rolled materials have high hardness, and toothed fixtures can easily cause surface damage, so flat fixtures can be used. Different types of rolled materials (such as brittle materials and soft materials) require suitable fixtures (such as flat fixtures and toothed fixtures). If the fixtures are not matched and replaced in a timely manner, the sample can easily be crushed, torn, or its surface damaged, affecting the accurate reflection of tensile properties.

[0004] Therefore, it is necessary to be able to easily replace different fixtures and quickly adapt to diverse testing needs. Utility Model Content

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.

[0026] Please see Figure 1-6 The present invention provides the following technical solution:

[0027] A roll tensile testing device includes a tensile testing structure 1, a lifting structure 3 on the top of the tensile testing structure 1, a protective frame 4 on the top of the tensile testing structure 1, an electric lifting rod 5 connected to the top of the protective frame 4, a pre-assembly frame 6 connected to the front side of the lifting structure 3, a quick-assembly mechanism 2 movably connected to the inner wall of the pre-assembly frame 6, a clamping plate 7 on the front side of the quick-assembly mechanism 2, and a threaded rod 8 on the inner wall of the clamping plate 7.

[0028] The quick-installation mechanism 2 includes an installation block 201, a connecting plate 202, and a fixing plate 203. The top of the fixing plate 203 is connected to the bottom of the connecting plate 202, the top of the connecting plate 202 is connected to the bottom of the installation block 201, and the surface of the installation block 201 is movably connected to the inner wall of the pre-installation frame 6.

[0029] In this embodiment: By setting up a quick-installation mechanism 2, the installation block 201 is fixed to the position of the connecting plate 202, and the connecting plate 202 is fixed to the position of the fixing plate 203. The installation block 201 is movably connected to the inner wall of the pre-installation frame 6, realizing the quick disassembly and replacement of the clamping plate 7 and the fixing plate 203. There is no need for complicated operation procedures. Operators can quickly switch between different specifications and types of quick-installation mechanisms 2 to adapt to various roll material testing needs, simplify operation steps, and improve the convenience and efficiency of pre-test preparation and fixture maintenance. By setting up an electric lifting rod 5 and a protective frame 4, the protective frame 4 creates a safe protective space for the roll material tensile testing process. With the cooperation of the electric lifting rod 5 and the lifting structure 3, the electric lifting rod 5 can flexibly adjust the lifting of the protective frame 4, which can effectively block the danger of sample breakage and splashing, and ensure personnel safety. The lifting structure 3 can drive the quick-installation mechanism 2 and the clamping plate 7 to perform the roll material tensile testing.

[0030] Specifically, such as Figure 5 As shown, a bearing 9 is fixedly connected to the inner wall of the clamping plate 7, and the inner wall of the bearing 9 is fixedly connected to the surface of the threaded rod 8.

[0031] Specifically, such as Figure 4 , Figure 6 As shown, the front side of the connecting plate 202 is connected to the limiting frame 10, the bottom of the limiting frame 10 is connected to the limiting plate 11, and the surface of the threaded rod 8 is threadedly connected to the inner wall of the limiting plate 11.

[0032] Specifically, such as Figure 5 As shown, a rotating plate 12 is connected to the front side of the threaded rod 8, and a rotating rod 13 is connected to the surface of the rotating plate 12.

[0033] In this embodiment: By setting the bearing 9, the subsequent screw can rotate on the inner wall of the clamping plate 7 through the bearing 9, and the clamping force of the clamping plate 7 near the fixed plate 203 can be adjusted by the threaded rod 8, so as to ensure that the roll sample is uniformly stressed. The setting of the rotating plate 12 and the rotating rod 13 allows the operator to easily rotate the threaded rod 8, so as to ensure that the roll can be stably clamped, improve clamping efficiency and detection accuracy, and at the same time prevent the sample from shifting or slipping during the stretching process.

[0034] Specifically, such as Figure 3 , Figure 4 As shown, a knob 14 is movably connected to the inner wall of the pre-mounted bracket 6. The surface of the knob 14 is threadedly connected to the inner wall of the mounting block 201.

[0036] In this embodiment: By setting a knob 14, the knob 14 can be rotated on the inner wall of the pre-mounting frame 6 and the mounting block 201 during use, which makes it easy to restrict the mounting block 201 to the inner wall of the pre-mounting frame 6. The threaded hole 15 opened on the inner wall of the mounting block 201 makes it easy for the knob 14 to rotate on the inner wall of the mounting block 201 through the threaded hole 15. By setting a stabilizing rod 16, the position of the stabilizing rod 16 and the clamping plate 7 can be fixed during use, which can enhance the lateral stability of the clamping plate 7 and prevent the clamping plate 7 from shaking when moving.

[0037] Specifically, such as Figure 2 As shown, the top of the tensile testing structure 1 is connected to a slide rod 17, and the inner wall of the protective frame 4 is slidably connected to the surface of the slide rod 17.

[0038] Specifically, such as Figure 2 As shown, the top of the slide bar 17 is connected to the mounting structure 18, and the bottom of the mounting structure 18 is connected to the top of the electric lifting rod 5.

[0039] In this embodiment: by setting a slide bar 17, the slide bar 17 and the protective frame 4 are slidably engaged during use, providing stable guiding support for the lifting and lowering of the protective frame 4, avoiding deviation or shaking during the lifting and lowering of the electric lifting rod 5. The mounting structure 18 at the top of the slide bar 17 stably connects the electric lifting rod 5 and the tensile detection structure 1, making the lifting and lowering action of the protective frame 4 more stable and smooth, while improving the overall structural strength of the protective frame 4 and ensuring the stable operation of the safety protection function.

During use, the mounting block 201 is fixed to the position of the connecting plate 202, and the connecting plate 202 is fixed to the position of the fixing plate 203. The mounting block 201 is movably connected to the inner wall of the pre-installation frame 6, enabling quick disassembly and replacement of the clamping plate 7 and the fixing plate 203. No complicated operating procedures are required; operators can quickly switch between different specifications and types of quick-installation mechanisms 2 to adapt to diverse roll material testing needs, simplifying operating steps and improving the convenience and efficiency of pre-test preparation and fixture maintenance. An electric lifting rod 5 and a protective frame 4 are set up. The protective frame 4 creates a safe protective space for the roll material tensile testing process. With the cooperation of the electric lifting rod 5 and the lifting structure 3, the electric lifting rod 5 can flexibly adjust the lifting of the protective frame 4, effectively preventing dangers such as sample breakage and splashing, ensuring personnel safety. The lifting structure 3 can drive the quick-installation mechanism 2 and the clamping plate 7 to perform the roll material tensile testing.
