Description

Technical Field

[0001] This utility model relates to the field of round steel testing technology, specifically to a rapid testing platform for round steel bending. Background Technology

[0002] In the steel processing and manufacturing industry, round steel bars or pipes are crucial raw materials, and their quality directly impacts the operating efficiency of subsequent processing equipment and the quality of finished products. However, during the transportation, handling, and storage of raw materials, round steel bars may bend due to various factors. When the bending degree of the round steel exceeds a certain range, the processing equipment will malfunction, leading not only to decreased production efficiency but also potential equipment damage and increased production costs.

[0003] To ensure the proper functioning of processing equipment, round steel bars with curvature exceeding the specified range must be screened and rejected. However, when producing large batches of round steel bars, the workload of inspecting and screening each bar individually is enormous. Traditional manual inspection methods are not only time-consuming and labor-intensive, but also lack accuracy and efficiency. Therefore, how to quickly and accurately detect the curvature of round steel bars has become an urgent problem to be solved.

[0004] To address the aforementioned issues, there is currently no equipment on the market that can both meet the needs of rapid testing and guarantee testing accuracy for round steel bending. Traditional testing methods often require complex measuring tools, which are not only cumbersome to operate but also difficult to adapt to the needs of batch testing. Therefore, developing a testing device that can quickly and in batches identify round steel bending values ​​exceeding the specified values ​​is of great significance for improving production efficiency and reducing production costs.

[0005] Based on the above background, this utility model proposes a rapid testing station for round steel bending, which aims to achieve rapid and accurate testing of the bending degree of round steel through a simple and practical design, meeting the needs of batch feeding production lines and batch inspection upon arrival. Utility Model Content

[0006] To address the aforementioned issues, this utility model provides a rapid testing station for round steel bending. This rapid testing station and method for round steel bending offer fast and intuitive testing, are simple and practical, and have low manufacturing and maintenance costs. They can be applied to production lines with batch material supply, batch testing, and other scenarios.

[0007] The technical solution of this utility model is as follows:

[0008] A rapid testing table for round steel bending includes two parallel guide rails, with the support surfaces at the top of the two guide rails respectively used to support the two ends of the round steel, and the support surfaces are inclined surfaces.

[0009] The two ends of the guide rail are fixed to the ground by support leg I and support leg II, respectively.

[0010] One end of the guide rail is hinged to the top of support leg I, and the other end of the guide rail overlaps the top of support leg II.

[0011] The height of outrigger II is adjustable.

[0012] Specifically, outrigger II is a telescopic push rod.

[0013] The guide rail is hinged to support leg I via a connecting shaft.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model discloses a rapid testing station for round steel bending. The rapid testing station and testing method for round steel bending realize the rapid detection and screening of the bending degree of round steel. Compared with the traditional method, this method does not require additional measuring tools, which greatly saves the testing time and improves the work efficiency.

[0016] 2. The present invention discloses a rapid testing table for round steel bending. The rapid testing table and testing method for round steel bending are intuitive and easy to judge: during the testing process, the rolling state of the round steel on the support surface directly reflects its bending degree; the continuous rolling of the round steel indicates that the bending degree is within the qualified range, while stopping after rolling indicates that the bending degree exceeds the standard. This intuitive testing method is easy to operate and understand.

[0017] 3. The present invention discloses a rapid testing table for round steel bending, which is flexible and adjustable in terms of both the testing table and the testing method: the angle between the support surface and the horizontal plane is adjustable, so that the testing table can adapt to the needs of different bending degree testing standards; by adjusting the angle, different bending degree testing thresholds can be easily set to meet the requirements of different quality standards.

[0018] 4. The present invention discloses a round steel bending rapid testing table. The testing principle of the round steel bending rapid testing table and testing method is based on the principle of mechanics. The rolling state of the round steel on the support surface is affected by gravity, support force and bending degree. By reasonably designing the included angle of the support surface and the testing method, the bending degree of the round steel can be scientifically and accurately determined.

[0027] This utility model comprises: 1. support frame, 1-1. connecting shaft, 1-2. guide rail, 1-3. support leg I, 1-4. support leg II, 1-5. support surface, 2. round steel, 3. ground. Detailed Implementation

[0028] Example 1 Figure 1 , Figure 2 and Figure 3 As shown, the round steel bending rapid testing table includes two parallel guide rails 1-2. The top of the two guide rails 1-2 is provided with a support surface 1-5 for supporting the two ends of the round steel 2. The support surface 1-5 is an inclined surface that forms a certain angle with the horizontal plane.

[0029] Furthermore, both ends of the guide rail 1-2 are fixedly mounted on the ground 3 via support legs I1-3 and II1-4, respectively; one end of the guide rail 1-2 is hinged to the top of support leg I1-3 via connecting shaft 1-1, so that the guide rail 1-2 can rotate around the hinge point, and the other end of the guide rail 1-2 overlaps or is hinged to the top of support leg II1-4, forming a reliable connection with support leg II1-4.

[0030] Preferably, the height of the outrigger II 1-4 is adjustable to accommodate different angle requirements. Specifically, the outrigger II 1-4 can be in the form of a telescopic push rod, and its height can be changed by adjusting the length of the telescopic push rod, thereby adjusting the angle between the support surface 1-5 of the guide rail 1-2 and the horizontal plane; the telescopic push rod can be a hydraulic push rod, an electric push rod, or other telescopic lifting method.

[0031] The rapid detection method for round steel bending includes the following steps:

[0032] Step 1: Adjust the angle of the testing platform. Based on the pre-calculated values, adjust the height of the support leg II 1-4 so that the support surface 1-5 of the guide rail 1-2 forms a predetermined angle with the horizontal plane. This step can be achieved through observation or measurement to ensure the accuracy of the angle.

[0033] Step 2: Place the round steel. Place both ends of the round steel 2 to be tested on two parallel support surfaces 1-5 that are at an angle to the horizontal plane. Ensure that the round steel 2 is perpendicular to the support frame 1 and that its length is less than the distance between the two support frames 1 to ensure that the round steel 2 can be stably placed on the support surfaces 1-5.

[0034] Step 3: Observe the rolling of the round steel. When the actual curvature of round steel 2 does not exceed the curvature detection value corresponding to the included angle of support surfaces 1-5, round steel 2 will continuously roll towards the lower end along support surfaces 1-5 under the action of gravity. This is because when round steel 2 is placed on the inclined plane, its gravity G and the inclined plane support force F form a resultant force F1, causing round steel 2 to have a tendency to roll towards the lower position. Figure 4 As shown. However, when the actual curvature of round steel 2 is greater than the curvature detection value corresponding to the included angle of support surfaces 1-5, round steel 2 will stop rolling on the inclined plane after rolling a certain angle. This is because after round steel 2 bends, its center of gravity is not on the same straight line as the geometric center of the cross-section of the two round steels at the support surface position, and there is a certain deviation. The greater the curvature, the greater the deviation. As round steel 2 rolls, its center of gravity position changes continuously, causing the torque M2 generated at the relative contact point O to gradually increase. When M2 is greater than the torque M1 that makes the round steel continue to roll, round steel 2 will stop rolling, as shown. Figure 5 As shown.

[0035] Step 4: Determine the curvature of the round steel. By observing the rolling of round steel 2 on support surfaces 1-5, it can be determined whether its curvature exceeds the standard. If round steel 2 can continuously roll to the lower end of support surfaces 1-5, it indicates that its curvature is within the acceptable range; if round steel 2 stops rolling after rolling a certain angle, it indicates that its curvature exceeds the standard and it is an unqualified material.

[0036] Step 5: Adjust the angle and repeat the test. If necessary, the angle between the support surface 1-5 and the horizontal plane can be changed by adjusting the height of the outriggers II1-4, thereby adjusting the bending range of the defective round steel. Then, repeat steps two through four to test the next batch of round steel.

[0037] The working principle of this invention is based on the rolling characteristics of round steel on an inclined plane. For example... Figure 4 and Figure 5As shown, when a round steel bar is placed on an inclined plane, its weight G and the supporting force F of the inclined plane form a resultant force F1, causing the round steel bar to tend to roll towards the lower position. Relative to the contact point O, this generates a torque M1 = G × L1. However, when the round steel bar bends, its center of gravity is not collinear with the geometric center of the cross-section of the two round steel bars at the supporting surface; there is a certain deviation. As the round steel bar rolls, its center of gravity position continuously changes, causing the torque M2 generated relative to the contact point O to gradually increase, M2 = G × L2. When M2 exceeds the torque M1 required for the round steel bar to continue rolling, the round steel bar will stop rolling. By observing the rolling behavior of the round steel bar on the inclined plane, it is possible to determine whether its bending degree exceeds the standard.

[0038] In Example 2, the spacing between support legs I1-3 and support legs II1-4 is set to be adjustable to accommodate round steel bars 2 of different lengths. Specifically, the bottoms of support legs I1-3 and support legs II1-4 are mounted on the ground 3 via linear guide rail modules and are equipped with motor drive devices. The spacing between support legs I1-3 and support legs II1-4 can be adjusted along the linear guide rail modules by the drive device. By adjusting the spacing between support legs I1-3 and support legs II1-4, the spacing between the two guide rails 1-2 can be adjusted, thereby adapting to the detection requirements of round steel bars 2 of different lengths.

[0039] In Example 3, the specific values ​​of the bending degree detection can be obtained through experimental measurement. That is, a batch of round steel bars 2 with different bending degrees, lengths, diameters, or materials are obtained through other detection methods. Through reverse experiments using this batch of round steel bars 2, a database of bending degree detection values ​​for round steel bars of different lengths, bending degrees, diameters, or materials corresponding to each specific included angle is obtained. Preferably, the telescopic push rod is a product with a telescopic length display, such as a servo electric push rod, and is connected to a PLC with a touch screen. The bending degree detection value database is stored in the PLC. The length, diameter, material, and other parameters of the round steel bars 2 are input into the PLC. The telescopic push rod telescopic length can be input through the touch screen, and the included angle between the support surface and the horizontal plane can be displayed intuitively, thus displaying the corresponding bending degree detection value intuitively.

[0040] In Example 4, the guide rail 1-2 is configured as a segmented structure. Each segment is hinged and its tilt angle can be adjusted by individual support legs II1-4. Different tilt angles of different segments can be set with multiple bending detection values ​​at the same time, so that round steel with different bending degrees can be detected simultaneously by the round steel bending rapid detection table.

[0041] Example 5: To ensure consistent rolling conditions during long-term use and to avoid detection deviations caused by oil contamination, support surfaces 1-5 are coated with a superhydrophobic nano-coating, and grooves are designed on their surfaces to guide oil or debris to slide off automatically.

[0042] This invention determines whether the curvature of a round steel bar exceeds the standard by observing its rolling motion on an inclined plane, eliminating the need for specialized measuring tools and providing a quick and intuitive testing process. Adjusting the height of the support legs II1-4 changes the tilt angle of the guide rails 1-2, adapting to different testing requirements. This makes the invention widely applicable, meeting the testing needs of round steel bars of various specifications and requirements. The invention's simple and clear structure makes it easy to operate; users only need to follow the steps in the instruction manual to complete the testing task, without requiring complex training or guidance. The relatively low manufacturing and maintenance costs of this invention give it a strong competitive edge in the market. Furthermore, its high testing efficiency and accuracy save users significant time and labor costs.

[0043] This invention can be applied to production lines with batch feeding and batch testing scenarios, providing an effective solution for the rapid detection of the curvature of round steel bars. Furthermore, this invention can also be applied to fields such as the measurement of the roundness of round steel bars, and has broad application prospects.
