Description

Technical Field

[0001] This utility model belongs to the field of coating adhesive testing technology, and in particular relates to a tensile strength testing fixture for wear-resistant coating adhesive. Background Technology

[0002] Wear-resistant coating adhesives are wear-resistant coatings formulated with various resins and elastomers. After being applied to a metal surface and cured naturally or by heat, the resulting wear-resistant coating is also known as a chemically bonded wear-resistant coating. In the performance testing of wear-resistant coating adhesives, tensile strength is an important indicator, reflecting the strength and toughness of the coating material under tensile load. Tensile testing is a test method for determining the properties of materials under axial tensile load. The data obtained from tensile testing can determine the material's elastic limit, elongation, elastic modulus, proportional limit, reduction of area, tensile strength, yield point, yield strength, and other tensile performance indicators.

[0003] The existing announcement number CN221959852U discloses a tensile strength testing fixture for wear-resistant coated adhesive. During the coating and setting process, the air in the adhesive is removed, which improves the accuracy of the test.

[0004] The aforementioned patent removes air bubbles from the glue by vibrating it. However, vibrating the glue can easily lead to uneven distribution of the glue, resulting in different thicknesses or deformation after the glue solidifies. This affects the accuracy of the glue tensile strength test results. Furthermore, the glue has strong adhesion when set, and pushing it out can also damage the shape of the glue. Utility Model Content

The adhesive removes air bubbles by vibrating it, but vibration can easily lead to uneven distribution of the adhesive, resulting in different thicknesses or deformation after solidification, which affects the accuracy of the tensile strength test results. In addition, the adhesive has strong adhesion when set, and ejecting it can also destroy the shape of the adhesive.

[0006] This utility model is implemented as follows: a tensile strength testing fixture for wear-resistant coated adhesive, comprising:

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0035] It is understood that the terms “first” and “second” as used herein may be used to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0036] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0037] like Figures 1 to 3 As shown, a tensile strength testing fixture for wear-resistant coated adhesive provided in one embodiment of this utility model includes:

[0038] Test stand 1, which is equipped with tensile component 2 and load-bearing component 3, is used to perform tensile tests on the coated adhesive.

[0039] Moving component 5, set on test bench 1, includes:

[0040] An electric telescopic column 51 is fixedly installed on the test bench 1. A fixed frame 52 is fixedly installed on the output shaft of the electric telescopic column 51. An air outlet is provided on the fixed frame 52.

[0041] Softening mechanism 53, mounted on the fixing frame 52, is used to soften the coated adhesive. Softening mechanism 53 includes:

[0042] The fixed box 531 is fixedly installed on the fixed frame 52, and the fixed box 531 is provided with an air inlet hole;

[0044] Heating wire 534 is fixedly installed on the fixed box 531 and is used to heat the coated adhesive.

[0045] In this embodiment of the present invention, in practical application, the adhesive is applied to the bearing component 3. After the application is completed, if air bubbles appear in the adhesive, the electric telescopic column 51 is activated to move the softening mechanism 53 through the fixing frame 52. At the same time, the second motor 532 and the heating wire 534 are energized. The second motor 532 drives the fan blade 533 to rotate, blowing the heat emitted by the heating wire 534 towards the location where air bubbles appear in the adhesive. After the adhesive softens, the air bubbles can be expelled. Then, wait for the adhesive to solidify, and then perform a tensile strength test on the adhesive through the stretching component 2.

[0046] By setting up the softening mechanism 53, the air bubbles generated after the glue is applied can be heated to soften the glue and remove the air bubbles. This is more effective than removing air bubbles by vibration, prevents deformation of the glue, and avoids uneven distribution of the glue after removing air bubbles, thus improving the tensile strength test results of the glue.

[0047] like Figure 2 and Figure 3 As shown, in a further embodiment of this utility model, the moving component 5 further includes a demolding mechanism 54, which is disposed on the fixed frame 52 and is used to demold the coated adhesive. The demolding mechanism 54 includes:

[0050] The delivery pipe 543 is fixedly installed on the delivery pump 542 and is used to deliver the release agent;

[0051] Sprayer 544 is fixedly installed on delivery pipe 543 and is used to spray release agent;

[0052] In this embodiment of the present invention, in actual application, the delivery pump 542 sprays the release agent inside the storage tank 541 from the sprayer 544 onto the support platform 31 through the delivery pipe 543. The fixing frame 52 moves with the extension and retraction of the electric telescopic column 51, so that the release agent is evenly sprayed onto the support platform 31, which facilitates the subsequent demolding of the glue.

[0053] like Figure 1 and Figure 2 As shown, in a further embodiment of this utility model, the tensioning component 2 includes:

[0054] The positive and negative lead screws 21 are rotatably fitted on the test bench 1. The positive and negative lead screws 21 and the nut slider 22 form a helical pair transmission, and the nut slider 22 is slidably fitted with the test bench 1.

[0055] Support frame 23 is fixedly installed on nut slider 22;

[0056] The lower clamping plate 24 is fixedly installed on the support frame 23;

[0057] The upper clamping mechanism 25 is mounted on the support frame 23. The upper clamping mechanism 25 includes a clamping cylinder and an upper clamping plate. The clamping cylinder is fixedly mounted on the support frame 23, and the upper clamping plate is fixedly mounted on the output shaft of the clamping cylinder.

[0058] The first motor 26 is fixedly installed on the test bench 1, and the output end of the first motor 26 is connected to the positive and negative lead screws 21.

[0059] In this embodiment of the utility model, in actual application, the glue after demolding and shaping is placed on the lower clamping plate 24 and clamped and fixed by the upper clamping mechanism 25. Then, the first motor 26 outputs power to drive the positive and negative lead screws 21 to rotate. The nut slider 22 is affected by the screw pair transmission, causing the support frame 23 to move, and the glue is subjected to a tensile drive test.

[0060] like Figure 1 and Figure 2 As shown, in a further embodiment of this utility model, the supporting component 3 includes:

[0061] The support platform 31 is fixedly installed on the test platform 1, and the support platform 31 is provided with a support groove for shaping the coated adhesive.

[0062] Hydraulic rod 32 is fixedly installed on bearing platform 31. Bearing plate 33 is fixedly connected to the output shaft of hydraulic rod 32. Bearing plate 33 is slidably engaged with bearing platform 31.

[0063] Specifically, as a further embodiment of this utility model, it also includes a heat conduction component 4, which is disposed on the test bench 1 and is used to conduct heat to the support platform 31. The heat conduction component 4 includes a conduction box, an electric heating rod, a discharge plug and a sealing cover.

[0064] In this embodiment of the present invention, when the adhesive is applied to the support groove on the support platform 31, the release agent is first sprayed onto the support platform 31. After the adhesive is formed, it is then heat-conducted through the heat conduction component 4.
