Description

Technical Field

[0001] The present invention relates to the technical field of round steel detection, and particularly relates to a rapid round steel bending detection table and a detection method. Background Art

[0002] In the steel processing and manufacturing industry, round steel bars or round steel pipes, as important raw materials, their quality directly affects the operating efficiency of subsequent processing equipment and the quality of finished products. However, during the transportation, handling, and storage of raw materials, due to the influence of various factors, round steel may be bent. When the bending degree of round steel exceeds a certain range, the processing equipment will not be able to work properly, which will not only lead to a decrease in production efficiency, but may also cause equipment damage and increase production costs.

[0003] In order to ensure the normal operation of processing equipment, it is necessary to screen and remove round steel with a bending degree exceeding the specified range. However, when the quantity of round steel is large, the workload of detecting and screening one by one is huge. The traditional manual detection method is not only time-consuming and laborious, but also difficult to guarantee the detection accuracy and efficiency. Therefore, how to quickly and accurately detect the bending degree of round steel has become an urgent problem to be solved.

[0004] In response to the above problems, there is currently no round steel bending detection equipment on the market that can both meet the requirements of rapid detection and ensure the detection accuracy. Traditional detection methods often require the use of complex measuring tools, which are not only cumbersome to operate, but also difficult to adapt to the needs of batch detection. Therefore, developing a detection equipment that can quickly and batch identify round steel with a bending degree exceeding the specified value is of great significance for improving production efficiency and reducing production costs.

[0005] Based on the above background, the present invention proposes a rapid round steel bending detection table and a detection method, aiming to achieve rapid and accurate detection of the bending degree of round steel through a simple and practical design, and meet the requirements of scenarios such as batch feeding production lines and arrival batch detection. Summary of the Invention

[0006] In order to solve the above problems, the present invention provides a rapid round steel bending detection table and a detection method. The rapid round steel bending detection table and the detection method are rapid, intuitive, simple and practical, with low manufacturing and maintenance costs of finished products, and can be applied to scenarios such as batch feeding production lines and batch detection.

[0007] The technical solution of the present invention is as follows: A rapid round steel bending detection table includes two parallel guide rails. The supporting surfaces at the tops of the two guide rails are respectively used to support the two ends of the round steel, and the supporting surfaces are inclined surfaces.

[0008] Both ends of the guide rails are fixedly arranged on the ground through leg Ⅰ and leg Ⅱ respectively.

[0009] One end of the guide rail is hinged to the top of the leg Ⅰ, and the other end of the guide rail is lapped on the top of the leg Ⅱ.

[0010] The height of the leg Ⅱ is adjustable.

[0011] Specifically, the leg Ⅱ is a telescopic push rod.

[0012] The guide rail is hinged to the leg Ⅰ through a connecting shaft.

[0013] A rapid detection method for the bending of round steel. The two ends of the round steel are respectively placed on two parallel supporting surfaces that form an angle with the horizontal plane. When the actual bending degree of the round steel does not exceed the bending degree detection value corresponding to the angle of the supporting surface, the round steel continuously rolls towards the lower end along the supporting surface. When the actual bending degree of the round steel is greater than the bending degree detection value corresponding to the angle of the supporting surface, the round steel cannot continuously roll along the supporting surface and finally stops rolling.

[0014] By setting the angle between the supporting surface and the horizontal plane to different angles, the bending degree detection value changes with the change of the angle.

[0015] The beneficial effects of the present invention are as follows: 1. A rapid detection table and detection method for the bending of round steel disclosed by the present invention. The rapid detection table and detection method for the bending of round steel achieve rapid detection and screening of the bending degree of round steel; compared with the traditional method, this method does not require additional measuring tools, greatly saves the detection time, and improves the work efficiency.

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

[0017] 3. A rapid detection table and detection method for the bending of round steel disclosed by the present invention. The rapid detection table and detection method for the bending of round steel are flexibly adjustable: the angle between the supporting surface and the horizontal plane is adjustable, enabling the detection table to meet the requirements of different bending degree detection standards; by adjusting the angle, different bending degree detection thresholds can be conveniently set to meet the requirements of different quality standards.

[0018] 4. A rapid detection table and detection method for the bending of round steel disclosed by the present invention. The detection principle of the rapid detection table and detection method for the bending of round steel is based on the mechanical principle. The rolling state of the round steel on the supporting surface is affected by gravity, supporting force, and bending degree; by reasonably designing the angle of the supporting surface and the detection method, the bending degree of the round steel can be scientifically and accurately judged.

[0019] By reading the detailed description of the preferred embodiments below, the solutions and advantages of the present application will become clear to those of ordinary skill in the art. The drawings are only for the purpose of showing the preferred embodiments and are not considered to be a limitation of the present invention.

[0020] In the drawings: Figure 1 is a schematic structural diagram of a rapid detection table for bending round steel according to an embodiment of the present invention; Figure 2 is Figure 1 the top view of Figure 3 is a schematic structural diagram of a support frame of a rapid detection table for bending round steel according to an embodiment of the present invention; Figure 4 is a schematic diagram of the force on the support surface when the round steel is not bent; Figure 5 is a schematic diagram of the force on the support surface after the round steel is bent; The components represented by the reference numerals in the drawings are: The present invention: 1. Support frame, 1-1. Connecting shaft, 1-2. Guide rail, 1-3. Leg Ⅰ, 1-4. Leg Ⅱ, 1-5. Support surface, 2. Round steel, 3. Ground. Specific embodiments

[0021] Embodiment 1 As Figure 1 , Figure 2 and Figure 3 shown, the rapid detection table for bending round steel includes two parallel guide rails 1-2. A support surface 1-5 is provided at the top of the two guide rails 1-2 for supporting both ends of the round steel 2; the support surface 1-5 is an inclined surface and forms a certain angle with the horizontal plane.

[0022] Furthermore, both ends of the guide rail 1-2 are fixedly arranged on the ground 3 through leg Ⅰ 1-3 and leg Ⅱ 1-4 respectively; wherein, one end of the guide rail 1-2 is hinged to the top of leg Ⅰ 1-3 through a 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 is lapped or hinged to the top of leg Ⅱ 1-4 and forms a reliable connection with leg Ⅱ 1-4.

[0023] Preferably, the height of the leg Ⅱ 1-4 is adjustable to meet the requirements of different angles. Specifically, the leg Ⅱ 1-4 can be in the form of a telescopic push rod, and the height is changed by adjusting the length of the telescopic push rod, so as to adjust 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 methods.

[0024] The rapid detection method for bending round steel includes the following steps: Step 1: Adjust the angle of the detection table. According to the pre-measured values, adjust the height of the second leg 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 by observation or measurement to ensure the accuracy of the angle.

[0025] Step 2: Place the round steel. Place the two ends of the round steel 2 to be detected on two parallel support surfaces 1-5 that form an angle with the horizontal plane. Ensure that the round steel 2 is perpendicular to the support frame 1 and 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 surface 1-5.

[0026] Step 3: Observe the rolling situation of the round steel. When the actual bending degree of the round steel 2 does not exceed the bending degree detection value corresponding to the angle of the support surface 1-5, the round steel 2 will continuously roll towards the lower end along the support surface 1-5 under the action of gravity. This is because when the 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 the round steel 2 to have a tendency to roll towards the lower position, as Figure 4 shown. However, when the actual bending degree of the round steel 2 is greater than the bending degree detection value corresponding to the angle of the support surface 1-5, the round steel 2 will stop rolling on the inclined plane after rolling a certain angle. This is because after the round steel 2 is bent, its center of gravity is not on the same straight line as the geometric center of the cross-section of the two round steel positions on the support surface, with a certain deviation. The greater the bending, the greater the deviation. As the round steel 2 rolls, the position of its center of gravity continuously changes, resulting in the moment M2 generated relative to the contact point O gradually increasing. When M2 is greater than the moment M1 that enables the round steel to continue rolling, the round steel 2 will stop rolling, as Figure 5 shown.

[0027] Step 4: Judge the bending degree of the round steel. By observing the rolling situation of the round steel 2 on the support surface 1-5, it can be judged whether its bending degree exceeds the standard. If the round steel 2 can continuously roll to the lower end of the support surface 1-5, it means that its bending degree is within the qualified range; if the round steel 2 stops rolling after rolling a certain angle, it means that its bending degree exceeds the standard and it is unqualified material.

[0028] Step 5: Adjust the angle and repeat the detection. As needed, the angle between the support surface 1-5 and the horizontal plane can be changed by adjusting the height of the second leg 1-4, so as to adjust the bending range of the unqualified round steel. Then, repeat steps 2 to 4 to detect the next batch of round steel.

[0029] The working principle of the present invention is based on the rolling characteristics of round steel on an inclined plane. As Figure 4 and Figure 5As shown in the figure, when the round steel is placed on the inclined plane, its gravity G and the supporting force F of the inclined plane form a resultant force F1, causing the round steel to have a tendency to roll towards the lower position. Relative to the contact point O, a moment M1 = G × L1 is generated. However, when the round steel is bent, 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 supporting surface position, with a certain deviation. As the round steel rolls, the position of its center of gravity continuously changes, resulting in a gradual increase in the moment M2 generated relative to the contact point O, M2 = G × L2. When M2 is greater than the moment M1 that enables the round steel to continue rolling, the round steel will stop rolling. By observing the rolling situation of the round steel on the inclined plane, it is possible to determine whether its degree of bending exceeds the standard.

[0030] In Embodiment 2, the distance between the supporting legs Ⅰ1-3 and the supporting legs Ⅱ1-4 is set to an adjustable structure to adapt to round steels 2 of different lengths. Specifically, the bottoms of the supporting legs Ⅰ1-3 and the supporting legs Ⅱ1-4 are installed on the ground 3 through a linear guide rail module, and a motor driving device is provided. The distance between the supporting legs Ⅰ1-3 and the supporting legs Ⅱ1-4 can be adjusted along the linear guide rail module by driving the driving device. By adjusting the distance between the supporting legs Ⅰ1-3 and the supporting legs Ⅱ1-4, the distance between the two guide rails 1-2 can be adjusted, so as to meet the detection requirements of round steels 2 of different lengths.

[0031] In Embodiment 3, the specific values of the bending degree detection values can be obtained through actual measurement in experiments, that is, a batch of round steels 2 with different bending degrees, different lengths, different diameters or different materials are obtained through other detection means, and a database of bending degree detection values of round steels with different lengths, different bending degrees, different diameters or different materials corresponding to each specific angle is obtained through reverse experiments on this batch of round steels 2; preferably, the telescopic push rod is selected as a product with a display of the telescopic length, such as a servo electric push rod, and is connected to a PLC with a touch screen. The database of bending degree detection values is stored in the PLC. The parameters such as the length, diameter, and material of the round steel 2 are input into the PLC, and the telescopic length of the telescopic push rod can be input through the touch screen, and the angle between the supporting surface and the horizontal plane can be intuitively displayed, and the corresponding bending degree detection value can be intuitively displayed.

[0032] In Embodiment 4, the guide rail 1-2 is set as a segmented structure, and each segment is hinged and the inclination angle of each segment can be adjusted through a separate supporting leg Ⅱ1-4. Different inclination degrees of different segments can set multiple bending degree detection values at the same time, so as to detect round steels with different bending degrees simultaneously through this round steel bending rapid detection platform.

[0033] In Embodiment 5, to ensure consistent rolling conditions during long-term use and avoid detection deviations caused by oil stains, the supporting surface 1-5 adopts a superhydrophobic nano-coating, and a groove design is made on its surface to guide the automatic sliding of oil stains or debris.

[0034] The present invention determines whether the degree of bending of round steel exceeds the standard by observing the rolling condition of the round steel on an inclined plane, without the need to use professional measuring tools, and the detection process is fast and intuitive; by adjusting the height of the second leg 1-4, the inclination angle of the guide rail 1-2 can be changed, so as to adapt to different detection requirements. This makes the present invention have wide applicability and can meet the detection requirements of round steel of different specifications and requirements; the structure of the present invention is simple and clear, the operation is convenient and easy to understand, and the user only needs to operate according to the steps in the instruction manual to complete the detection task, without the need for complex training and guidance; the manufacturing cost and maintenance cost of the present invention are relatively low, which makes it have great competitiveness in the market. At the same time, due to its high detection efficiency and high accuracy, it can save a large amount of time and labor costs for users.

[0035] The present invention can be applied to scenarios such as production lines with batch feeding and batch detection, providing an effective solution for the rapid detection of the degree of bending of round steel. In addition, the present invention can also be applied to fields such as the measurement of the roundness of round steel, and has broad application prospects.
