Description

Technical Field

[0001] This utility model belongs to the technical field of preparation of wear test specimens for rotating bottles of slurry mixtures, and specifically relates to an apparatus for preparing wear test specimens for rotating bottles of slurry mixtures. Background Technology

[0002] Slurry mixtures are an important material widely used in road engineering, waterproofing engineering and other fields. Their compatibility and abrasion resistance are directly related to the quality and durability of the project. The rotating bottle abrasion test of slurry mixtures is a key means of evaluating its performance. By simulating the wear conditions in actual use, the mass loss rate is used as an indicator to judge the durability of the mixture and provide a scientific basis for engineering applications. However, the accuracy of the test results is highly dependent on the integrity and standardization of the specimen preparation.

[0003] In the existing process of preparing wear specimens for rotary bottles of slurry mixtures, a short pressure head, a mold sleeve, and a mold table are usually used in conjunction with a traditional electronic universal testing machine for molding. The specific operation is as follows: the short pressure head moves downward under the drive of the electronic universal testing machine to press the slurry mixture in the mold sleeve into a cylindrical block specimen.

[0004] However, after the specimen is formed, due to the adhesion between the mold and the specimen and the limitations of the mold structure, the specimen is difficult to remove smoothly from the mold. If the specimen is forcibly demolded with external force, it is very easy to cause damage to the edge of the specimen, surface scratches or internal structure damage, which will affect the integrity and dimensional accuracy of the specimen. This non-standard demolding process will directly cause the test results to deviate from the actual performance of the mixture, reduce the reliability of the compatibility and wear resistance performance evaluation, and may even cause hidden dangers in engineering quality. Therefore, this utility model proposes a device for preparing wear specimens of slurry mixture in a rotating bottle. Utility Model Content

[0026] 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.

[0027] Example 1

[0028] Please see Figures 1 to 6 This is the first embodiment of the present invention, which provides the following technical solution: an apparatus for preparing abrasion test specimens of a slurry mixture in a rotating bottle, comprising...

[0029] The lower support plate 1 is installed on the bottom inner side of the electronic universal testing machine 6, and the cylindrical stripping table 2 is installed on the top surface of the lower support plate 1 for placing the existing mold sleeve 4. The top surface of the stripping table 2 is provided with an adapter groove 21. The electronic universal testing machine 6 can be a common electronic universal testing machine on the market, such as the WDW-200 / 300 microcomputer-controlled electronic universal testing machine. The working principle and structural composition of such common electronic universal testing machines on the market are common knowledge to those in the technical field, and will not be elaborated here.

[0030] The upper pressure plate 3 installed at the bottom of the drive seat 61 inside the electronic universal testing machine 6, and the long pressure head 5 installed at the bottom of the upper pressure plate 3 and adapted to the existing mold sleeve 4, are used in actual use. After the existing mold sleeve 4 completes the molding and pressing of the internal slurry mixture rotating bottle wear specimen, the operator can place the existing mold sleeve 4 on the top of the unloading table 2, and then start the electronic universal testing machine 6, so that the drive seat 61 moves down with the upper pressure plate 3 and the long pressure head 5, so that the long pressure head 5 is stably inserted into the inside of the existing mold sleeve 4 based on the constant pressure characteristics of the existing electronic universal testing machine 6, and gradually pushes the slurry mixture rotating bottle wear specimen in the existing mold sleeve 4 from the bottom to the inside of the unloading table 2 with constant pressure, avoiding damage to the specimen caused by direct external force, ensuring that the specimen edges are smooth, the surface is free of defects, and the original molding state is completely preserved, providing high-precision samples for wear tests;

[0031] And the connecting structure set between the unloading table 2 and the lower support plate 1.

[0032] In this embodiment, preferably, the length of the long pressure head 5 is the same as the length of the existing mold sleeve 4, so that after the long pressure head 5 is pushed into the inside of the existing mold sleeve 4 by the upper pressure plate 3, it can smoothly push the already formed slurry mixture rotating bottle wear test piece into the inside of the existing mold sleeve 4 to the inside of the unloading platform 2. The outer edge of the bottom end of the long pressure head 5 is designed with a rounded chamfer, so that the bottom end of the long pressure head 5 can be easily inserted into the inside of the existing mold sleeve 4.

[0033] In this embodiment, preferably, the size of the adapter slot 21 is adapted to the size of the existing mold sleeve 4, so that the bottom end of the existing mold sleeve 4 can be stably placed in the adapter slot 21.

[0034] In this embodiment, preferably, the connecting structure includes an annular positioning seat 11 fixed to the top surface of the lower support plate 1, and the bottom end of the unloading platform 2 is inserted into the inner side of the annular positioning seat 11, so that the unloading platform 2 can be stably limited and prevent horizontal displacement during subsequent use. Multiple L-shaped rubber brackets 12 are glued to the top surface of the annular positioning seat 11, and the L-shaped rubber brackets 12 surround the unloading platform 2. The inner side of the L-shaped rubber brackets 12 is provided with an integral hemispherical block 121. Both are made of rubber material and will undergo elastic deformation when squeezed. The surface of the unloading platform 2 is provided with an annular groove 22 for the hemispherical block 121 to be inserted into. When the bottom end of the unloading platform 2 is inserted into the inner side of the annular positioning seat 11, the hemispherical block 121 will be squeezed into the annular groove 22, thereby limiting the unloading platform 2 in a certain vertical direction, playing an auxiliary limiting role, and further ensuring the installation stability of the unloading platform 2.

[0035] In this embodiment, preferably, the top surface of the long pressure head 5 is provided with an integrated top seat 51, and the top of the top seat 51 is provided with an integrated threaded post 53. The bottom surface of the upper pressure plate 3 is welded and fixed with a connecting seat 31, and the bottom surface of the connecting seat 31 is provided with a threaded connecting pad 32 for the threaded post 53 to be screwed into. This allows the long pressure head 5 to be screwed into the threaded connecting pad 32 during installation, thus completing the stable installation of the long pressure head 5 at the bottom of the upper pressure plate 3. It also facilitates subsequent disassembly and replacement. The surface of the top seat 51 is fixed with multiple protrusions 52, which facilitates the rotation and twisting of the top seat 51 by the operator during subsequent disassembly and assembly.

[0036] Example 2

[0037] Please see Figures 1 to 7 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that a circular bottom groove 13 is also provided on the top surface of the lower support plate 1 relative to the inner side of the annular positioning seat 11, and a rubber buffer pad 14 is installed on the inner side of the circular bottom groove 13. The rubber buffer pad 14 is a hollow structure and is made of rubber. This allows the slurry mixture rotating bottle wear test specimen in the existing mold sleeve 4 to fall on the top of the rubber buffer pad 14 when the subsequent long pressure head 5 pushes it out from the bottom of the existing mold sleeve 4. Under the action of the rubber buffer pad 14, the slurry mixture rotating bottle wear test specimen will be buffered to a certain extent, avoiding unnecessary bumps during the ejection, and further ensuring the integrity of the slurry mixture rotating bottle wear test specimen.

[0038] In this embodiment, preferably, the bottom surface of the rubber buffer pad 14 is provided with an integrated U-shaped insert 141, and both sides of the U-shaped insert 141 are provided with integrated side locking blocks 142. Both are made of rubber material and will undergo elastic deformation when squeezed. The inner wall of the bottom end of the circular bottom groove 13 is provided with a rectangular slot 131 for inserting the U-shaped insert 141, and both sides of the inner wall of the rectangular slot 131 are provided with side locking grooves 132 for the side locking blocks 142 to be inserted, so that the rubber buffer pad 14 can be stably installed in the circular bottom groove 13, ensuring its own installation stability.

[0039] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
