Description

Technical Field

[0001] This utility model relates to the field of compressive strength testing technology for nano-insulation boards, and in particular to a device for testing the compressive strength performance of nano-insulation boards. Background Technology

[0002] Nano-insulation panels are a new type of refractory and thermal insulation material made using nanoscale heat transfer technology. They possess characteristics such as inhibiting the thermal movement of gas molecules. They are made primarily from nanoscale silica powder, along with fibers and other additives, through pressing, followed by sintering or the use of binders to form the final product. During the production of nano-insulation panels, it is necessary to test their compressive strength.

[0003] The current practice is as follows: the sample of the nano-insulation board to be tested is placed in the workpiece placement area (flatness less than 0.5 mm) on the worktable of a compression testing machine (hydraulic pressure machine). Then, the compression testing machine is started and the sample is pressed down at a specified rate until it breaks, and the load is recorded. However, this practice has the following drawbacks: 1. The workpiece placement area and pressing area of ​​the compression testing machine are often subjected to large uneven forces, resulting in reduced flatness (pitting), which affects the subsequent test results; 2. The broken sample is scattered on the worktable of the compression testing machine, requiring staff to clean it up with an air gun or broom. This not only wastes a lot of staff time, but also easily causes dust from the breakage to fly around during the cleaning process, affecting the indoor environment.

[0004] To address this, we provide a device for testing the compressive strength of nano-insulation panels. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model discloses a device for testing the compressive strength of nano-insulation panels.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for testing the compressive strength of a nano-insulation board includes a main body of a compressive testing machine. The workpiece placement area of ​​the main body of the compressive testing machine is equipped with a replaceable feeding platform and a slag receiving tray around the periphery of the replaceable feeding platform. The outer edge of the slag receiving tray is provided with an upward-turned edge.

[0008] The bottom of the lower pressure column of the main body of the compression testing machine is equipped with a replaceable pressure head.

[0009] Furthermore, an annular magnetic block is adsorbed in the center of the workpiece placement area, and an insertion hole is provided on the inner side of the annular magnetic block;

[0010] The lower section of the replaceable feeding platform is matched and plugged into the socket.

[0011] Furthermore, the replaceable discharge platform has a stepped surface in the middle, which is pressed against the inner edge of the slag receiving tray.

[0012] Furthermore, the insertion socket is higher than the annular magnetic block, and its upper end is provided with a tapered edge, which contacts the bottom surface of the slag receiving tray to maintain the horizontal stability of the slag receiving tray.

[0013] Furthermore, the replaceable feeding platform has a lower prism section and an upper cylindrical section.

[0014] Furthermore, the bottom of the pressure column is provided with a slant, and a conical annular groove is provided above the slant. An inner conical flange plate is fitted into the conical annular groove. A threaded sleeve is provided at the bottom of the inner conical flange plate. The upper part of the replaceable pressure head is provided with an internal thread that mates with the threaded sleeve.

[0015] Furthermore, the inner conical flange plate is composed of two spliced ​​sections, both of which are connected to the top of the threaded sleeve by bolts. By rotating the threaded sleeve, the replaceable pressure head can be driven to move axially, thus completing the disassembly or installation of the replaceable pressure head.

[0016] Furthermore, the top of the upper flange is higher than the replaceable feeding platform.

[0017] Furthermore, the outer edge of the inner cavity of the slag receiving tray is provided with a recessed portion for collecting slag fragments.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The interchangeable feeding platform and interchangeable pressure head allow for replacement when pits or unevenness appear on the working surface, ensuring the accuracy of test results. The interchangeable feeding platform achieves quick fixation through a combination of annular magnetic blocks and insertion sockets. The interchangeable pressure head achieves axial adjustment through the cooperation of a threaded sleeve and an inner tapered flange plate, enabling quick replacement.

[0020] 2. The slag receiving tray completely surrounds the sample area, preventing debris from splashing. The recessed design on the outer edge of the inner cavity of the slag receiving tray can concentrate and collect the crushed debris. Cleaning can be completed simply by removing the slag receiving tray, greatly reducing manual cleaning time and preventing dust diffusion, thus improving the working environment. At the same time, the conical edge of the insertion seat contacts the bottom surface of the slag receiving tray, distributing the force, and the replacement feeding platform presses the slag receiving tray together, improving the stability of the slag receiving tray.

Further, its lower section is a prism section, its upper section is a cylinder section, and a stepped surface 21 is provided in the middle. Specifically, the stepped surface 21 faces downwards and presses against the inner edge of the slag receiving tray 3 to ensure the stability of the slag receiving tray 3. Depending on the needs, the lower section of the replaceable feeding platform 2 can be a quadrangular or hexagonal prism.

[0032] The replaceable feeding platform 2 is designed as a prism section. When pits appear on the top surface of the replaceable feeding platform 2, the lower section of the replaceable feeding platform 2 can be clamped by a vise, and the top surface of the replaceable feeding platform 2 can be milled by a milling machine to repair and reuse the replaceable feeding platform 2.

[0033] Slag receiving tray 3: It is arranged around the replaceable feeding platform 2, with an upward-turned edge 31 on the outer edge and a top height higher than the replaceable feeding platform 2, and is used to collect the slag after the sample is crushed. The outer edge of the inner cavity of the slag receiving tray 3 has a recessed part, which can gather the slag and prevent the slag from falling out of the central hole of the slag receiving tray 3 during the process of picking up the slag receiving tray 3.

This mounting hole is fitted into the bottom of the lower pressure column 4, with the bottom surface of the mounting hole fitting against the bottom surface of the lower pressure column 4. That is, by rotating the threaded sleeve 9, the replaceable pressure head 5 can be driven to move axially, realizing the quick disassembly or installation of the pressure head.

[0035] Furthermore, the inner tapered flange plate 8 is composed of two spliced ​​sections, which are connected to the top of the threaded sleeve 9 by bolts.
