Description

Technical Field

[0001] The invention relates to the technical field of thin-wall aluminum profile frame detection, in particular to a pressure bearing test tool for a thin-wall aluminum profile frame. Background Art

[0002] Thin-walled aluminum profile frames are widely used in many fields such as building doors and windows, curtain walls, protective fences and frame structures of industrial equipment due to their light weight, high strength, beautiful appearance and easy processing and installation. For example, in large glass curtain walls of modern buildings, thin-walled aluminum profile frames, as key components for supporting and fixing glass, need to withstand a variety of complex external forces such as wind loads, deadweight and possible accidental impact. In terms of industrial equipment protection, they must be able to withstand a certain degree of collision and vibration. These application scenarios place strict requirements on the pressure bearing capacity of thin-walled aluminum profile frames. Therefore, accurately testing their pressure bearing performance has become a key link in ensuring safety and reliability.

[0003] In conjunction with the above, it should be noted that: Chinese patent with announcement number CN115326578A discloses a photovoltaic module aluminum frame strength testing device, which adaptively clamps and fixes frames of different sizes, and performs extrusion detection on multiple sides of the frame through a detection plate; however, during the actual detection, due to the influence of the main structure of the aluminum profile frame, the internal frame is squeezed and damaged, and simple observation is not easy to detect frame abnormalities in time.

[0025] Embodiment 2: This embodiment is a pressure bearing test tool for a thin-walled aluminum profile frame, including a movable end cover 204 arranged on the top of a fixed end cover 2, an observation cover 3 arranged between the movable end covers 204, an upper supporting guide rail 302 arranged on the inner wall of the observation cover 3, an upper extrusion mechanism 8 is slidably sleeved on the surface of the upper supporting guide rail 302, and the upper extrusion mechanism 8 includes an upper movable base 801 and an outer arc frame 802.

[0026] A lifting guide column 201 is embedded on the top of the fixed end cover 2 and is sleeved with the movable end cover 204. A lifting motor 203 is provided on the outer wall of the end of the movable end cover 204 away from the observation cover 3, and the lifting motor 203 is in transmission connection with the lifting guide column 201. A water outlet valve 202 is provided on the inner wall of the end of the fixed end cover 2 facing the clamping mechanism 5. The water pump is started through the control panel. The water pump is installed inside the fixed end cover 2, and the water pump is connected to the liquid storage tank 6 and the water outlet valve 202 through pipe fittings, and forms a water delivery route with the connecting hose 503 and the water outlet 505; The water pump draws test water through the water delivery route and pours it into one end of the thin-walled aluminum profile frame until it is filled up, and guides the air in the thin-walled aluminum profile frame along the water delivery route at the other end to the liquid storage tank 6, so that the interior of the thin-walled aluminum profile frame is completely filled with test water, which constitutes the preparation before the test. It should be noted that the test water is pure water mixed with dye and fluorescent agent, which causes the thin-walled aluminum profile frame to overflow along the rupture after it is damaged by test extrusion, and the rupture area is marked.

[0027] A movable cover plate 301 is hinged on the side of the observation cover 3, and the upper support guide rail 302 is fixedly installed at the center of the top inner wall of the observation cover 3, and the upper support guide rail 302 and the lower support guide rail 103 are symmetrically arranged up and down, and the lower support guide rail 103 is fixed at the center of the bottom inner wall of the inner arc cover 101. When the observation cover 3 is closed with the measuring platform base 1, the lifting motor 203 drives the movable end cover 204 to slide down along the lifting guide column 201 through related accessories until the movable end cover 204 is connected to the fixed end cover 2, which simultaneously drives the observation cover 3 to slide down until the upper extrusion mechanism 8 inside the observation cover 3 is close to the lower extrusion mechanism 4.

[0028] The top of the upper movable base 801 is slidably sleeved with the upper support rail 302, and the bottom of the upper movable base 801 is provided with an inner telescopic frame 805 connected to the outer arc frame 802, and the center of the bottom frame of the outer arc frame 802 is provided with an outer telescopic frame 803 connected to the inner telescopic frame 805, and the bottom of the outer telescopic frame 803 is provided with an upper extrusion plate 804, and the upper movable base 801 moves along the surface of the upper support rail 302, thereby driving the upper extrusion mechanism 8 and the lower extrusion mechanism 4 to keep moving synchronously, and the inner telescopic frame 805 drives the outer arc frame 802 to slide down synchronously, and the inner telescopic frame 1 401 drives the arc bracket 1 402 to slide upward synchronously, so as to achieve upper and lower docking, so as to promote the temporary splicing of the lower extrusion mechanism 4 and the upper extrusion mechanism 8 to form a circular pressure-bearing mechanism, which is used to perform multi-region synchronous extrusion test processing on the outer peripheral wall of the thin-walled aluminum profile frame; Among them, the outer telescopic frame 803 drives the upper extrusion plate 804 to slide down, and it keeps synchronization with the movement of the lower extrusion plate 409 to achieve the upper and lower coordinated pressure-bearing test of the thin-walled aluminum profile frame. When the side extrusion plate 408 is moved close to the thin-walled aluminum profile frame, the side telescopic frame 407 is used to drive them close to each other to perform the left and right coordinated pressure-bearing test on both sides of the thin-walled aluminum profile frame.

[0029] During the pressure test of the thin-walled aluminum profile frame, the external tester can record and observe the test process in real time through the observation cover 3. The process of the thin-walled aluminum profile frame being squeezed can be directly seen through the observation cover 3 and the transparent acrylic material of the movable cover plate 301, which is used to record the changes in its squeezed shape; When the outer wall of the thin-walled aluminum profile frame is squeezed and deformed, the inside of the frame remains filled with test water. The test water is compressed as the size of the load environment changes. When the surface of the thin-walled aluminum profile frame is locally compressed, there is a rupture phenomenon, which causes the test water to overflow along the rupture area. The test water produces a mark after contacting the rupture area. At the same time, the test water falls onto the test paper 7 laid in the liquid collecting tank 102 below, causing the test paper 7 to be contaminated and change color, which helps to record the pressure state, deformation process and damage state after pressure of the thin-walled aluminum profile frame. A pipe for connecting to a liquid storage tank is set at the bottom of the liquid collecting tank 101 for recycling the dripping test water.

[0030] Embodiment three: This embodiment is a pressure bearing test tool for a thin-walled aluminum profile frame, including a test supervision system, a control panel is arranged on the outer wall of the test bench base 1, and high-definition recording sensors are arranged on the inner walls of the test bench base 1 and the observation cover 3 adjacent to each other, for collecting frame change reference values ​​generated by the test of the thin-walled aluminum profile frame, a pressure sensor is arranged inside the limit extrusion disk 502, for collecting frame pressure internal variable values ​​generated by the test of the thin-walled aluminum profile frame, an integrated sensor is arranged on the inner wall of the bottom of the test bench base 1, for collecting abnormal leakage data values ​​generated by the test of the thin-walled aluminum profile frame, and the collected frame change reference values, frame pressure internal variable values ​​and abnormal leakage data values ​​are sent to the cloud database via the control panel.

[0031] The test monitoring system is used to collect, record, analyze and give test results of the pressure test process of thin-walled aluminum profile frames inside the test fixture, such as Fig.10 As shown, the test supervision system firstly sets high-definition recording sensors on the inner walls adjacent to the test platform base 1 and the observation cover 3. The high-definition recording sensors in the test platform base 1 are located on the inner walls on both sides of the top of the inner arc cover 101. The high-definition recording sensors are used to collect the frame change reference values ​​generated by the thin-walled aluminum profile frame under test; The frame change reference value is expressed as the value of the thin-walled aluminum profile frame being squeezed and shrunk after being squeezed. A pressure sensor is provided inside the limit squeeze plate 502, and the pressure sensor is connected to the water port 505. A regulating valve is provided inside the water port 505 to adjust the injection of test water and detect and prevent backflow due to pressure. It is used to collect the frame pressure internal change value generated by the thin-walled aluminum profile frame being tested. The frame pressure internal change value indicates the thin-walled aluminum profile frame body being deformed after being subjected to pressure. After the internal filling test water is synchronously squeezed, the pressure change caused by the contact valve inside the water outlet 505 is measured. An integrated sensor is arranged on the inner wall at the bottom of the test platform base 1. The integrated sensor is composed of a humidity sensor and an industrial camera. The humidity sensor is installed inside the liquid collecting tank 102 and affixed with the detection paper 7. The industrial camera is installed on the inner wall at the bottom of both sides of the inner arc cover 101, and is used to face the detection paper 7 to collect the abnormal leakage data value generated by the thin-walled aluminum profile frame being tested. The abnormal leakage data value is represented by the number of times the internal test water drips on the test paper after the thin-walled aluminum profile frame is squeezed and cracked; The collected frame variable reference values, frame pressure internal variable values ​​and abnormal missing data values ​​are marked as KBi, KCi and YLi respectively, and sent to the cloud database via the control panel. The above data is only the current test data. The relevant data needs to be readjusted for subsequent position change or re-test.

[0032] After receiving the frame variable reference value KBi, frame pressure internal variable value KCi and missing data value YLi, the cloud database analyzes the test results of the test tooling step by step, and analyzes the current test results with this group of data. Obtain the pressure bearing coefficient; Among them, q, w and e are the proportional coefficients of the frame variable reference value KBi, the frame pressure internal variable value KCi and the abnormal leakage data value YLi respectively, q>w>e>0, R represents the pressure coefficient, the proportional coefficient is a parameter used to measure the contribution of the frame variable reference value KBi, the frame pressure internal variable value KCi and the abnormal leakage data value YLi to the pressure coefficient, and the proportional coefficient represents the relative weight of each variable in the comprehensive result of calculating the pressure coefficient, and is not limited to this. It is adjusted according to the actual test, and the preset pressure coefficient YR is retrieved from the cloud database for comparison and analysis with the pressure coefficient R: If the pressure coefficient R>the preset pressure coefficient YR, it is judged that there is an abnormality in the test, and the thin-walled aluminum profile frame tested is marked as unqualified, and a poor signal is generated. The poor signal is sent to the display screen of the control panel, and the text in the format of "Test number 0013 / Poor quality / Data record / Unqualified mark" is used to remind the tester who operates the testing tooling to verify the test results, record the data, and promptly remove the group of thin-walled aluminum profile frames and clean the testing tooling for the next group of thin-walled aluminum profile frames to be tested and processed.

[0033] If the pressure coefficient R is less than the preset pressure coefficient YR, the group of tests is judged to be normal, and the thin-walled aluminum profile frame tested is marked as qualified. At the same time, a high-quality signal is generated and sent to the control panel with text in the format of "Test number 0013 / Quality qualified / Data retained / Whether to conduct a second test" to remind the tester to take the next step according to the test results.

[0034] When a poor signal is generated, the cloud database simultaneously marks the frame variation reference value KBi, frame pressure internal variation value KCi and abnormal leakage data value YLi that generate the poor signal, and retrieves the pre-stored frame variation sample value, frame pressure sample value and abnormal leakage sample value from the cloud database for comparison and analysis with the frame variation reference value KBi, frame pressure internal variation value KCi and abnormal leakage data value YLi: If the frame variation reference value KBi is not within the range of the frame variation sample value, and the frame pressure internal variable value KCi is within the range of the frame pressure sample value, and the abnormal leakage data value YLi is less than the abnormal leakage sample value, then the thin-walled aluminum profile frame bearing pressure is judged to be unqualified, and a first-level signal is generated and sent to the display of the control panel, and the "Test number 0013 / Frame pressure is small / Specific parameters are retained" style text is displayed simultaneously, so that testers can quickly know the abnormal points of this group of thin-walled aluminum profile frames.

[0035] If the frame variation reference value KBi is within the range of the frame variation sample value, and the frame bearing pressure internal variation value KCi is not within the range of the frame bearing sample value, and the abnormal leakage data value YLi is less than the abnormal leakage sample value, then it is determined that the thin-walled aluminum profile frame material is defective and the internal bearing pressure is insufficient. A secondary signal is generated and sent to the display of the control panel, and the "Detection No. 0013 / Material Difference / Specific Parameters Retained" style text is displayed simultaneously, so that testers can quickly know the abnormal points of this group of thin-walled aluminum profile frames.

[0036] If the frame variation reference value KBi is within the range of the frame variation sample value, and the frame bearing internal variable value KCi is within the range of the frame bearing sample value, and the abnormal leakage data value YLi is greater than the abnormal leakage sample value, then it is determined that the thin-walled aluminum profile frame is easily damaged, and a three-level signal is generated and sent to the display of the control panel, and the "Detection serial number 0013 / Frame is easy to be damaged / Specific parameters are retained" style text is displayed simultaneously, so that testers can quickly know the abnormal points of this group of thin-walled aluminum profile frames.

[0037] Combining the first, second and third embodiments, it can be seen that the thin-walled aluminum profile frame is stably clamped and initially limited in the test platform base 1 by the cooperation of the clamping mechanism 5 and the lower extrusion mechanism 4, ensuring accurate position during the test. The observation cover 3 and the movable cover plate 301 are made of acrylic material, and the changes in the shape of the frame during the test can be observed in real time. The detection paper 7 in the liquid collection tank 102 can display the overflow of the test water to determine whether the frame is damaged. Multiple components cooperate to perform synchronous extrusion tests on multiple areas of the frame.

[0038] The test supervision system provides a basis for analysis under the coordination of multiple sensors, judges the test results by comparing the pressure coefficient with the preset value, generates signals and feeds them back to the control panel, generates different levels of signals for abnormalities and provides parameters. The test data is sent to the cloud database for storage and traceability, and its pre-stored parameters provide a benchmark for comparison and analysis.
