Description

Technical Field

[0001] The invention relates to the technical field of testing equipment, in particular to a microcomputer-controlled wire rope net bursting tester and a system working method thereof. Background Art

[0002] In the existing material mechanical properties testing technology, the bursting performance test of materials such as wire rope mesh is a key step in evaluating their structural strength and durability. However, the traditional bursting test machine has obvious shortcomings in technology and application.

[0003] First, traditional testing machines usually use a step-by-step control method for load application, that is, the gear position needs to be manually adjusted according to the load size during the test. This method is not only cumbersome to operate, but also because the load may fluctuate at the moment of gear switching, thus affecting the accuracy and reliability of the test results. Especially when conducting high-precision tests, even a slight change in load may have a significant impact on the final result.

[0004] Secondly, traditional testing machines also have limitations in control methods. Most traditional testing machines can only achieve a single closed-loop control, such as load closed-loop or displacement closed-loop, and cannot simultaneously meet the requirements of load, deformation, and displacement closed-loop control. This limits the application of testing machines in complex testing scenarios and also affects the comprehensiveness and accuracy of test results.

[0005] In addition, traditional testing machines also have obvious deficiencies in terms of safety assurance. Due to the lack of a complete protection mechanism, once an abnormal situation occurs during the test, such as overload, limit, overtemperature or overvoltage, the testing machine may not be able to respond in time and take corresponding protective measures, resulting in damage to operators and equipment.

[0006] Therefore, a microcomputer-controlled wire rope net bursting test machine and a system working method thereof are proposed to solve the above technical problems. Summary of the invention

[0060] The present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0061] like Figure 1-4 As shown, the present invention is a microcomputer-controlled wire rope net bursting tester, comprising:

[0062] Control host 1, used to control the operation of the entire test machine, including starting, stopping, adjusting test parameters and other functions;

[0063] The pin support frame 2, as the main structure of the testing machine, is used to support and fix other components;

[0064] The test base column 3 is connected to the control host 1 and installed below the pin support frame 2, and is used to carry and break the test sample;

[0065] A number of sample clamps 4 are evenly spaced and horizontally distributed on the pin support frame 2, and are used to clamp the test sample to ensure that the sample is stable and motionless during the test, and the clamping direction is inward to facilitate the punch to perform a burst test.

[0066] By adopting the above technical solution, through the integrated control of the control host 1, the start, stop and test parameter adjustment of the test machine can be automated, greatly improving the efficiency and accuracy of the test. The control host can accurately control various parameters in the test process, such as load application speed, bursting force, etc., to ensure the stability of the test results. The number of sample clamps 4 is evenly distributed on the pin support frame 2. This design allows the test samples to be evenly distributed and each sample can be stably clamped.

[0067] Test base column 3 includes:

[0068] The punch 31 is controlled by the control host 1 to move up and down during the test, and is used to directly break the test sample;

[0069] The guide light bars 32 are arranged on both sides of the top punch 31 to ensure that the top punch 31 moves in a straight line during the test and maintain the stability and accuracy of the movement direction;

[0070] The punch cylinder 33 is installed in the middle of the guide light bar 32 to provide punching power for the punch head 31 to ensure that it can perform the bursting test according to the preset force and speed.

[0071] By adopting the above technical scheme, the top punch 31 is precisely controlled by the control host 1, and can move up and down according to the preset force and speed to directly break the test sample. The guide light rods 32 are arranged on both sides of the top punch 31, which play a role in guiding and stabilizing the movement direction of the top punch. The top punch cylinder 33 is installed in the middle of the guide light rod 32, which provides a stable and controllable top punching power for the top punch 31. The top punch cylinder 33 can adjust the movement speed and breaking force of the top punch according to the instructions of the control host to ensure that the test process meets the preset test parameters.

[0072] The pin support frame 2 comprises:

[0074] The transverse welding beam 22 and the longitudinal welding beam 23 are both installed on the fixing seat 21 for elevation and support. There are two of them and they are arranged in parallel in a rectangular shape to provide a platform for installing and fixing the sample fixture 4 .

[0075] By adopting the above technical solution, the fixing base 21 serves as the basic part of the support frame, and its solid design ensures the stable installation of the entire support frame.

[0076] Pin holes 5 are provided on the transverse welding beam 22 and the longitudinal welding beam 23 for installing and fixing the sample fixture 4 to ensure that the sample fixture 4 will not loosen or shift during the test.

[0077] By adopting the above technical solution, the design of the pin hole 5 allows the sample fixture 4 to be firmly mounted on the beam by pinning. This fixing method is more stable than traditional bolt or buckle fixing, and can effectively prevent the fixture from loosening or shifting due to excessive force during the test. Installation and removal become simpler and faster, without the need for complicated bolt tightening or buckle operation, which greatly improves work efficiency.

[0078] The sample holder 4 includes:

[0079] The clamp joint 41 is mounted on the pin hole 5 through a high-strength screw 42 to ensure a firm connection between the clamp and the support frame;

[0081] The fixing rod 412 is used to further fix the test sample and increase the stability and reliability of the clamping.

[0082] By adopting the above technical solution, the clamp joint 41 is installed on the pin hole 5 through the high-strength screw 42 to ensure a firm connection between the clamp and the support frame. The coordinated use of the clamp groove 411 and the fixing rod 412 enables the sample clamp 4 to clamp test samples of different sizes and shapes. The clamp groove 411 is appropriately adjusted according to the shape of the sample, and the fixing rod 412 can further fix the sample.

[0083] The sample fixture 4 also includes a tensioning plate 43, which is installed on the sample fixture 4 on the transverse welded beam 22 and the longitudinal welded beam 23. The tensioning plate 43 is connected to the tail of the high-strength screw 42 of the sample fixture 4 on the transverse welded beam 22 and the longitudinal welded beam 23 to maintain the balance and uniformity of the clamping force and ensure the accuracy and reliability of the test results.

[0084] By adopting the above technical solution, the tensioning plate 43 further enhances the clamping stability of the sample clamp 4 on the test sample, and can provide additional support force during the test to prevent the sample from falling off or shifting due to excessive force, thereby ensuring the smooth progress of the test and reducing errors during the test.

[0085] The pin support frame 2 also includes:

[0086] The protective column 24 is installed above the transverse welded beam 22 and the longitudinal welded beam 23 to increase the height and stability of the support frame and prevent sample fragments from splashing and injuring people during the test;

[0087] The protective door 25 is installed on the front side of the protective column 24 to protect the operator from injury during the test and to facilitate observation and recording of test results.

[0088] By adopting the above technical solution, the protective column 24 increases the overall height of the support frame and significantly improves its stability. During the test, even if the sample is subjected to a strong bursting force, the support frame can remain stable. The protective column 24 can also block the splashing of sample fragments. The protective door 25 can block the splashing sample fragments and possible debris, protect the operator from injury, and improve safety.

[0089] The pin support frame 2 also includes a limiting beam 26, including a longitudinal limiting beam and a transverse limiting beam, both of which are 2 in number and are arranged in parallel to limit the punching position of the top punch 31, ensuring that the top punch 31 will not exceed the preset test range during the test, thereby ensuring the accuracy and safety of the test results.

[0090] By adopting the above-mentioned technical scheme, the limiting beam 26 can accurately limit the punching position of the top punch 31, ensuring that it will not exceed the preset test range during the test process, ensuring the accuracy and consistency of the test results, and making each test carried out according to the same standards and conditions, making the test process more controllable and stable, reducing the test interruption and readjustment time caused by loss of control of the top punch, and improving efficiency.

[0091] The control host 1 includes:

[0092] The general menu module 11 is used to manage file information and equipment hardware settings, including hand controller, PI14, test standards, definition rounding, parameter units, etc. Figure 5-8 , the file menu is used to edit the various states of the file, the setting interface menu is used to set and adjust the hardware and hardware parameters, the communication menu is the setting of the device selection in the online and offline states, and the test management menu is used to edit and save the test plan (basic parameters, number settings, thinning, user parameters, result parameters);

[0093] The numerical display module 12 is used to clearly and intuitively display the numerical values ​​of each parameter change;

[0094] The test control module 13 is used to adjust the moving speed of the crossbeam. The moving speed is displayed in mm / min. The test running speed can be dynamically changed during loading and unloading of samples or test operation. It has the function keys of upward movement - running upward at the set speed, downward movement - running downward at the set speed, stop - stop the test or stop the movement of the crossbeam, run - start the test, return to zero - return to force zero point, return to position zero point, clear - current display value is set to zero, and remove the extensometer - remove the extensometer during the small deformation test;

[0095] The interface display module 14 includes a user parameter interface, a single graph interface, a multi-graph interface and a query interface, which is used to display the test plan, brief information, basic information of the test sample, view a single or multiple coordinate curve graphs, and query, analyze and issue reports on historical test data, such as Fig. 9 , in the user parameter interface, area A is the edited test plan, area B is the brief information of the selected test plan, and area C is the basic information of the test sample;

[0096] like Fig.10 and Fig.11 In the single-graph interface, area A is the single-graph curve display area. Right-clicking areas C and D can change the X and Y axis coordinates. Area B is the result display area, which displays the "user parameters" and "result parameters" pre-programmed in the test plan. Area E contains the "Generate Report" and "Curve Analysis" buttons. You can also double-click anywhere in area A with the left mouse button to switch between the test result and curve analysis interfaces.

[0097] like Fig.12 In the multi-graph interface, you can see 3 arbitrary coordinate curve graphs at the same time. If you need to change the coordinates of multiple graphs, right-click below the horizontal axis or to the left of the vertical axis and select Change Coordinates.

[0098] like Fig.13 It is a query interface that can query based on file name, date, scheme or other conditions.

The working method applied to the microcomputer-controlled wire rope net bursting tester system is characterized in that: The specific steps include: Step 1: First, firmly fix the position of the pin support frame (2), adjust and determine the number and precise position of the sample fixtures (4) required on the pin support frame (2) according to the specific shape and size of the sample to be tested, and use the tensioning plate (43) to further reinforce and precisely adjust the installation position of the sample fixture (4) to ensure stability; Step 2: Place the sample to be tested in an appropriate position so that its four sides are centered within the range of the sample clamp (4) on the transverse welding beam (22) and the longitudinal welding beam (23), respectively, ensuring that the sample is within the clamping range; Step 3: After the sample is placed, connect and turn on the power supply, start the control host (1), the test software and the driving motor of the punch cylinder (33) on the pin support frame (2) in sequence, and ensure that the system is in a standby state; Step 4: Enter the experimental window interface of the test system, set the specific test plan and various test parameters in the test control module (13) according to the test requirements, adjust the top punch (31) to the specified position, and clear the force value on the numerical display module (12) to prepare for the start of the test; Step 5: Clamp the sample, connect and fix the sample to the sample fixture (4) on the transverse welding beam (22) and the longitudinal welding beam (23), install the extensometer on the top punch (31), click the start button on the test control module (13), and officially start the test. The system will operate according to the preset test plan and parameters. The test curve graph and data will be displayed on the interface display module (14) until the test is completed. After the test is completed, remove the extensometer and the system will automatically save the test data; Step 6: Remove the currently tested sample, replace it with a new sample, repeat the above steps 2 to 5, and proceed to the next round of testing.
