Description

TECHNICAL FIELD

[0001] The application relates to the technical field of curved rail processing, in particular to a curved rail manufacturing method and system, an intelligent terminal and a storage medium. BACKGROUND

[0002] The curved rail refers to a track with a certain curvature radius laid for changing direction. The curved rail is connected with a straight track and is usually used in combination with the straight track.

[0003] In related technology, first steel and second steel are obtained by cutting raw steel according to a curved rail cutting size. First original curved rails and second original curved rails are obtained by bending the first steel and the second steel. First sheared curved rails and second sheared curved rails are obtained by shearing the first original curved rails and the second original curved rails according to a curved rail design size. The curved rails are obtained by combining the first sheared curved rails and the second sheared curved rails.

[0004] In the related technology, the two sides of the curved rail are subjected to different resistances, resulting in different degrees of wear on the two sides of the curved rail, which affects the service life of the curved rail. SUMMARY

[0005] In order to improve the service life of the curved rail, the application provides a curved rail manufacturing method, system, intelligent terminal and storage medium.

[0006] In the first aspect, the application provides a curved rail manufacturing method, which adopts the following technical scheme: A curved rail manufacturing method comprises the following steps: cutting raw steel according to a curved rail cutting size to obtain first steel and second steel, the length of the first steel being less than the length of the second steel; bending the first steel and the second steel to obtain first original curved rails and second original curved rails; shearing the first original curved rails and the second original curved rails according to a curved rail design size to obtain first sheared curved rails and second sheared curved rails; fixing an inner lining piece on the outer side of the bending of the first sheared curved rail; polishing the inner lining piece; combining and fixing the first sheared curved rail and the second sheared curved rail through a positioning piece to obtain a curved rail.

[0007] By adopting the technical scheme, the inner lining piece is fixed at the bending outer side of the first shearing bent rail, and the core effect is to significantly enhance the structural rigidity and anti-deformation ability of the bent rail at the bending key stress position. The bending outer side is most prone to elongation and fatigue damage under stress, and the inner lining piece as a reinforcing component effectively disperses the stress borne by the area and suppresses the deformation tendency of the rail. Subsequently, the inner lining piece is polished to eliminate surface burrs and unevenness, which not only reduces friction and interference when assembling with subsequent positioning pieces or other components, but also ensures the tightness of the bent rail assembly, thereby improving the overall structural stability and service life of the final product.

[0008] Optionally, a positioning hole is formed in the inner lining piece. Obtain the current curvature of the first shearing bent rail; Calculate the difference between the current curvature and the preset curvature to obtain the lining processing curvature; Bend the inner lining piece according to the lining processing curvature; Weld the inner lining piece to the bending outer side of the first shearing bent rail; Form a screw hole in the first shearing bent rail through the positioning hole in the inner lining piece; Use a fixing screw to pass through the positioning hole and the screw hole to fix the inner lining piece on the bending outer side of the first shearing bent rail.

[0009] By adopting the technical scheme, a positioning hole is formed in the inner lining piece, which greatly optimizes the fixing effect and precision of the inner lining piece. First, based on the current curvature of the bent rail, the lining processing curvature is calculated and the inner lining piece is pre-bent to ensure that the inner lining piece can tightly fit the profile of the bending outer side, laying a foundation for effective reinforcement. Then, a screw hole is formed in the bent rail through the positioning hole, and a fixing screw is used for mechanical fastening, which forms a firm "weld-screw" double fixing mechanism. This design not only enables the inner lining piece to resist long-term vibration load and prevent falling off, but also provides accurate guidance for installation, ensuring the accuracy of the inner lining piece reinforcing position, thereby more reliably improving the local strength of the bent rail.

[0010] Optionally, the inner lining piece is placed on the bending outer side of the first shearing bent rail; Obtain the center position and two end positions of the inner lining piece; Form a first welding point at the center position; Form a second welding point at the edge position of the inner lining piece according to the path from the center position to the two end positions; Form a third welding point at the two end positions.

[0011] By adopting the above technical scheme, by stipulating a specific welding path from the center to the two ends, it is ensured that the inner lining sheet can be fixed flat and without warping on the outer side of the bent rail, which is crucial for realizing the best reinforcing effect. First, a first welding point is formed at the center position, which plays a role of preliminary positioning and "centering", preventing the inner lining sheet from sliding in subsequent operations. Then welding is performed from the center to the two end edges, which can orderly release welding stress, avoiding deformation of the inner lining sheet due to local overheating or generation of a gap with the rail surface, and ensuring close fitting between the two. Finally, a third welding point is applied at the two ends, completely eliminating the risk of end warping, so that the inner lining sheet uniformly reinforces the outer side of the bent rail as a whole, greatly improving the reliability of the reinforcing effect.

[0012] Optionally, the width information of the inner lining sheet is acquired; According to the width information and a preset welding point size, the number of welding points is obtained; According to the ratio of the width information and the number of welding points, the welding point spacing is obtained; According to the number of welding points and the welding point spacing, micro-welding treatment is performed at the two end positions to obtain the third welding point.

[0013] By adopting the above technical scheme, by fine processing of the third welding points at the two ends, the edge fixing quality of the inner lining sheet is optimized. According to the width information of the inner lining sheet, the number of welding points and the spacing are accurately calculated, and micro-welding is performed, which can ensure firm fixation of the end of the inner lining sheet while protecting the mechanical properties of the material, so that the inner lining sheet can more durably and stably play its role of reinforcing the anti-deformation ability of the bent rail. Moreover, the third welding point serves as a transition, allowing the roller to pass through the third welding point into the bent rail, so that the running effect of the bent rail is better.

[0014] Optionally, a morphological image of the third welding point is acquired; According to the morphological image, morphological information of the third welding point is acquired, including position information and contour information of the third welding point; According to the morphological information, an S-shaped polishing path is set; According to the S-shaped polishing path, polishing treatment is performed on the third welding point.

[0015] By adopting the technical scheme, an intelligent polishing scheme is provided for the third welding spot on the inner lining sheet. By acquiring the shape image of the welding spot and setting an S-shaped polishing path according to the shape image, efficient and accurate processing of the welding spot shape is realized. Such fine polishing can completely eliminate the sharp protrusions and burrs of the welding spot and form a smooth transition. The direct benefit is to avoid stress concentration at the welding spot position, and stress concentration is the root cause of the initiation of fatigue cracks when the curved rail is subjected to alternating loads. Therefore, the scheme not only improves the aesthetic appearance of the inner lining sheet area, but also essentially reduces the risk of early failure of the curved rail due to stress concentration at the inner lining sheet welding spot, prolonging the overall service life of the curved rail after strengthening.

[0016] Optionally, the actual curvature of the inner lining sheet is detected. In a case where the actual curvature is greater than the preset curvature and a difference between the actual curvature and the preset curvature is greater than a preset curvature difference value, after the first welding spot is formed at the center position, a temporary welding spot is determined on the inner lining sheet, and a distance from the temporary welding spot to the center position is a preset distance. A fourth welding spot is formed at the temporary welding spot. The fitting degree of the inner lining sheet and the first sheared curved rail is detected. In a case where the fitting degree meets a preset standard, the step of forming a second welding spot at an edge position of the inner lining sheet is continued to be executed according to the path from the center position to the two end positions.

[0017] By adopting the technical scheme, when it is detected that the actual curvature of the inner lining sheet deviates greatly from the preset value, a fourth welding spot is added after the center welding spot to actively and locally correct the shape of the inner lining sheet, so that the inner lining sheet better fits the outside of the curved rail. After confirming that the fitting degree meets the standard, subsequent welding is continued, which ensures that there is no internal stress caused by forced assembly between the inner lining sheet and the curved rail. This enables the inner lining sheet to be finally fixed in the most ideal contact state, thereby maximizing the load bearing efficiency of the inner lining sheet as a reinforcing component and ensuring the consistency and reliability of the reinforcing effect of the inner lining sheet in each curved rail.

[0018] Optionally, current size information of the curved rail is acquired. Historical size information of a previous curved rail is acquired. A difference between the current size information and the historical size information is calculated to obtain a size difference. If the size difference is greater than a preset size difference threshold, a manufacturing parameter of a next curved rail is adjusted according to the size difference.

[0019] By adopting the technical scheme, the consistency of the reinforcing effect of the inner lining is indirectly but systematically ensured by monitoring and adjusting the size information of the bent rail. Fluctuation of the size of the bent rail will directly affect the curvature and shape of the bent outer side, thereby causing the prefabricated inner lining to fail to achieve optimal fitting. By calculating the difference between the current and historical sizes and automatically adjusting the subsequent manufacturing parameters when the threshold is exceeded, the scheme can control the machining precision of the bent rail body from the source. This ensures that the bent outer side geometry of each bent rail is stable within the expected range, thereby creating a prerequisite for the accurate and effective fixation of the inner lining and ensuring the repeatability of the inner lining reinforcement process and the quality uniformity of the final product as a whole.

[0020] In a second aspect, the present application provides a bent rail manufacturing system, which adopts the following technical scheme: A bent rail manufacturing system comprises: An acquisition module is configured to acquire a cutting size of the bent rail and a design size of the bent rail. A memory is configured to store a program of the bent rail manufacturing method. A processor, and the program in the memory can be loaded and executed by the processor and implement the bent rail manufacturing method.

[0021] By adopting the technical scheme, the structure rigidity and anti-deformation ability of the bent rail at the key stress position of bending are significantly enhanced by fixing the inner lining on the bent outer side of the first sheared bent rail. The bent outer side is most prone to elongation and fatigue damage under stress, and the inner lining as a reinforcing component effectively disperses the stress borne by the area and suppresses the deformation tendency of the rail. Subsequent polishing of the inner lining eliminates surface burrs and unevenness, which not only reduces friction and interference when assembling with subsequent positioning pieces or other components, but also ensures the tightness of the bent rail assembly, thereby improving the overall structural stability and service life of the final product.

[0022] In a third aspect, the present application provides an intelligent terminal, which adopts the following technical scheme: An intelligent terminal comprises a memory and a processor, and the memory stores a computer program capable of being loaded and executed by the processor to implement the method of any one of the above.

[0023] In a fourth aspect, the present application provides a computer storage medium capable of storing a corresponding program, which has the characteristics of facilitating the improvement of the service life of the bent rail, and adopts the following technical scheme: A computer readable storage medium stores a computer program capable of being loaded and executed by a processor to implement any of the above bent rail manufacturing methods.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. By fixing the inner lining sheet on the outside of the first sheared and bent rail, the core function is to significantly enhance the structural rigidity and anti-deformation ability of the bent rail at the bending key stress position. The outside of the bending is most prone to elongation and fatigue damage under stress, and the inner lining sheet as a reinforcing component effectively disperses the stress in this area and suppresses the deformation tendency of the rail. Subsequent polishing of the inner lining sheet eliminates surface burrs and unevenness, which not only reduces friction and interference when assembling with subsequent positioning sheets or other components, but also ensures the tightness of the bent rail assembly, thereby improving the overall structural stability and service life of the final product. 2. By opening positioning holes in the inner lining sheet, the fixing effect and precision of the inner lining sheet are greatly optimized. First, based on the current curvature of the bent rail, the lining sheet processing curvature is calculated and the inner lining sheet is pre-bent to ensure that the inner lining sheet can closely fit the profile of the outside of the bending, laying the foundation for effective reinforcement. Then, screw holes are opened on the bent rail through the positioning holes, and mechanical fastening is performed using fixing screws, forming a firm "weld-screw" double fixation mechanism. This design not only enables the inner lining sheet to resist long-term vibration loads and prevent it from falling off, but also provides accurate guidance for installation, ensuring the accuracy of the inner lining sheet reinforcement position, thereby more reliably improving the local strength of the bent rail. 3. When the actual curvature of the inner lining sheet deviates significantly from the preset value, by adding a fourth welding point after the center welding point, the shape of the inner lining sheet can be actively and locally corrected to better fit the outside of the bent rail. After confirming that the fit meets the standards, continue with subsequent welding, which ensures that there is no internal stress caused by forced assembly between the inner lining sheet and the bent rail. This allows the inner lining sheet to be fixed in the most ideal contact state, thereby maximizing its load-bearing efficiency as a reinforcing component and ensuring the consistency and reliability of the inner lining sheet reinforcement effect in each bent rail.

[0035] In order to make the objectives, technical solutions and advantages of the present application clearer, the following further describes the present application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application. Figures 1 to 10 and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0036] An embodiment of the present application discloses a curved rail manufacturing method. Referring to Figure 1 , the method comprises: Step S101: according to a curved rail cutting size, performing cutting processing on raw steel material to obtain first steel material and second steel material, the length of the first steel material being less than the length of the second steel material.

[0037] The raw steel material is a C-shaped steel.

[0038] The curved rail cutting size refers to the length of the steel material cut from the raw steel material. Optionally, the curved rail cutting size comprises a first size and a second size. The first size is the cutting length of the first steel material, and the second size is the cutting length of the second steel material. The length of the first steel material and the length of the second steel material are both greater than the design size of the curved rail, so as to reserve sufficient redundancy.

[0039] Step S102: performing bending processing on the first steel material and the second steel material to obtain a first original curved rail and a second original curved rail.

[0040] The bending direction of the first steel material is away from the opening direction of the C-shaped steel, and the bending direction of the second steel material is toward the opening direction of the C-shaped steel.

[0041] Optionally, the angle of the bending processing is related to the design size of the curved rail.

[0042] Step S103: Shearing the first original curved rail and the second original curved rail according to the curved rail design size to obtain a first sheared curved rail and a second sheared curved rail.

[0043] The length of the first sheared curved rail and the second sheared curved rail meets the curved rail design size. After the first steel material and the second steel material are cut from the raw steel material, a redundant amount is reserved, and therefore the first original curved rail and the second original curved rail need to be sheared to ensure that their sizes meet the requirements.

[0044] For example, the first sheared curved rail is placed in the curved rail mold, and the part of the first sheared curved rail exposed from the curved rail mold is cut off.

[0045] Step S104: Fixing an inner lining sheet on the bending outer side of the first sheared curved rail.

[0046] The bending outer side refers to the convex surface of the first sheared curved rail. When the first sheared curved rail and the second sheared curved rail are assembled, the convex surface of the first sheared curved rail is arranged opposite to the concave surface of the second sheared curved rail.

[0047] The size of the inner lining sheet is matched with the bending outer side of the first sheared curved rail. It should be noted that the inner lining sheet is arranged only on the bending outer side of the first sheared curved rail. In the use process of the curved rail, the first sheared curved rail needs to bear the pressure from the roller, so that the first sheared curved rail is more easily worn than the second sheared curved rail, and therefore the inner lining sheet is fixed on the bending outer side of the first sheared curved rail.

[0048] Step S105: Polishing the inner lining sheet.

[0049] The polishing is used to remove the protrusions or burrs on the inner lining sheet, so that the roller can pass through the inner lining sheet more smoothly. For example, the inner lining sheet is polished by using a polishing device.

[0050] Step S106: Combining and fixing the first sheared curved rail and the second sheared curved rail by using a positioning sheet to obtain a curved rail.

[0051] The positioning sheet is used to fix the first sheared curved rail and the second sheared curved rail. For example, the first end of the first sheared curved rail and the first end of the second sheared curved rail are abutted on the fixing sheet. The first end of the first sheared curved rail and the first end of the second sheared curved rail are fixed on the fixing sheet by using a welding technique.

[0052] For example, please refer to Figure 2 The curved rail 21 is composed of the first sheared curved rail 211 and the second sheared curved rail 212, and the inner lining sheet 22 is further arranged on the inner wall of the first sheared curved rail 211.

[0053] By adopting the technical scheme, the inner lining piece is fixed at the bending outer side of the first shearing bent rail, and the core effect is to significantly enhance the structural rigidity and anti-deformation capability of the bent rail at the key stress position of bending. The bending outer side is most prone to elongation and fatigue damage under stress, and the inner lining piece as a reinforcing component effectively disperses the stress borne by the area and suppresses the deformation tendency of the rail. Subsequent polishing of the inner lining piece eliminates surface burrs and unevenness, which not only reduces friction and interference when assembling with subsequent positioning pieces or other components, but also ensures the tightness of the bent rail assembly, thereby improving the overall structural stability and service life of the final product.

[0054] In the following embodiments, it is necessary to firmly fix the inner lining piece on the first shearing bent rail to prevent the inner lining piece from falling off the first shearing bent rail. Therefore, the embodiments of the present application disclose a fixing method of an inner lining piece. Referring to Figure 3 , the method comprises: Step S301: A positioning hole is formed on the inner lining piece.

[0055] The positioning holes are uniformly distributed on the inner lining piece. For example, the inner lining piece is in a strip shape, the positioning holes are located on the symmetry axis of the inner lining piece, and the distance between adjacent positioning holes is the same.

[0056] For example, the inner lining piece is placed on a punching device. The positioning hole is formed on the inner lining piece by the punching device.

[0057] Step S302: Obtain the current curvature of the first shearing bent rail.

[0058] The current curvature is used to describe the bending degree of the first shearing bent rail.

[0059] For example, the first shearing bent rail is measured by using a curvature meter to obtain the current curvature. For example, the first shearing bent rail is scanned by using a three-dimensional scanner to obtain a digital model of the first shearing bent rail. The current curvature is obtained by the digital model.

[0060] In the embodiments of the present application, the curvature refers to the curvature of a curve, which can be considered as the curvature obtained by measuring the line after the first shearing bent rail is abstracted as a line along the side surface.

[0061] Step S303: Calculate the difference between the current curvature and the preset curvature to obtain the lining processing curvature.

[0062] The preset curvature is a preset empirical value, which can be considered as the processing error of the inner lining piece in curvature.

[0063] It should be noted that the lining processing curvature is less than the current curvature of the first shearing bent rail. Therefore, the bending degree of the inner lining piece after bending treatment is weaker than the bending degree of the first shearing bent rail.

[0064] Step S304: according to the liner processing curvature, the inner liner is subjected to bending treatment.

[0065] The curvature difference between the inner liner after bending treatment and the liner processing curvature is less than the curvature error value. Illustratively, the inner liner is subjected to bending treatment using a bending device.

[0066] Step S305: the inner liner is welded on the bending outer side of the first shear bending rail.

[0067] Illustratively, by micro welding technology, the welding points are formed on the inner liner and the first shear bending rail, so that the inner liner is fixed on the bending outer side of the first shear bending rail.

[0068] Step S306: a screw hole is formed on the first shear bending rail through the positioning hole on the inner liner.

[0069] Illustratively, the positioning hole on the inner liner is aligned using a drilling device. The drilling device is started to form a screw hole on the first shear bending rail, and the position of the screw hole is opposite to the positioning hole on the inner liner.

[0070] Further, the positioning hole on the inner liner is located on both sides of the inner liner, so that the roller does not pass above the positioning hole when passing through the inner liner.

[0071] Step S307: the inner liner is fixed on the bending outer side of the first shear bending rail by the positioning hole and the screw hole using a fixing screw.

[0072] By adopting the above technical solution, the fixing effect and precision of the inner liner are greatly optimized by forming the positioning hole on the inner liner. First, the liner processing curvature is calculated based on the current curvature of the bending rail, and the inner liner is pre-bent to ensure that the inner liner can closely fit the contour of the bending outer side, laying a foundation for effective strengthening. Then, the screw hole is formed on the bending rail through the positioning hole, and the mechanical fastening is performed using the fixing screw, which forms a firm "weld-screw" double fixing mechanism with the welding method. This design makes the inner liner not only resist long-term vibration load and prevent falling off, but also more reliably improve the local strength of the bending rail.

[0073] In the following embodiments, when forming the welding point, attention should be paid to the position of the welding point to reduce the difficulty of welding. Therefore, the present application discloses a welding point generation method. Referring to Figure 4 , the method comprises: Step S401: placing the inner liner on the bending outer side of the first shear bending rail.

[0074] The inner liner is placed on the bending outer side of the first shear bending rail for subsequent processing of the inner liner.

[0075] Step S402: Obtain the center position and the two end positions of the inner liner sheet.

[0076] The center position refers to the position of the center part of the inner liner sheet. For example, the center point of the inner liner sheet is taken as the center position.

[0077] The two end positions refer to the positions of the two ends of the inner liner sheet.

[0078] Step S403: Form a first welding point at the center position.

[0079] The first welding point refers to the welding point formed at the center position of the inner liner sheet.

[0080] Step S404: Form a second welding point at the edge position of the inner liner sheet according to the path from the center position to the two end positions.

[0081] The second welding point refers to the welding point formed at the edge position of the inner liner sheet.

[0082] Step S405: Form a third welding point at the two end positions.

[0083] The third welding point refers to the welding point formed at the two end positions of the inner liner sheet. It should be noted that the first welding point, the second welding point and the third welding point are the same in formation, only the positions are different.

[0084] By adopting the above technical solution, by specifying a specific welding path from the center to the two ends, it is ensured that the inner liner sheet can be fixed flat and without warping on the outside of the bent rail, which is crucial for achieving its best strengthening effect. First, the first welding point is formed at the center position, which plays the role of preliminary positioning and "centering", preventing the inner liner sheet from sliding in subsequent operations. Then, welding is performed from the center to the edge of the two ends, which can orderly release the welding stress, avoiding the deformation of the inner liner sheet due to local overheating or the generation of gaps with the rail surface, ensuring the close fit between the two. Finally, the third welding point is applied at the two ends, completely eliminating the risk of end lifting, so that the inner liner sheet uniformly strengthens the outside of the bent rail as a whole, greatly improving the reliability of the strengthening effect.

[0085] In the following embodiments, the inner liner sheet itself has a certain thickness, and when the roller enters the inside of the bent rail, the aforementioned thickness will affect the operation of the roller, therefore, in this embodiment, when forming the third welding point, the distance between the third welding points needs to be controlled to reduce the influence of the inner liner sheet. Therefore, the present application discloses a method for forming a third welding point. Referring to Figure 5 The method comprises: Step S501: Obtain the width information of the inner liner sheet.

[0086] The width information refers to the specific numerical value of the width of the inner liner sheet. For example, the width information is a preset value.

[0087] Step S502: obtaining the number of welding points according to the width information and the preset welding point size.

[0088] The preset welding point size refers to the diameter or radius of the welding point. The preset welding point size is a preset value. For example, the preset welding point size is the diameter of the welding point obtained by micro welding.

[0089] Exemplarily, a mapping relationship table of the width information, the preset welding point size and the number of welding points is set. In the mapping relationship table, the number of welding points is obtained according to the width information and the preset welding point size.

[0090] Step S503: obtaining the welding point spacing according to the ratio of the width information to the number of welding points.

[0091] Exemplarily, the ratio of the width value corresponding to the width information to the number of welding points is calculated to obtain the welding point spacing.

[0092] Step S504: performing micro welding processing at the two end positions according to the number of welding points and the welding point spacing to obtain third welding points.

[0093] Exemplarily, the micro welding processing is performed at the two end positions according to the number of welding points and the welding point spacing, so that the number of the obtained third welding points is consistent with the number of welding points, and the distance between adjacent third welding points is the welding point spacing.

[0094] Exemplarily, please refer to Figure 6 The third welding points 601 are formed at the two end positions of the inner lining sheet 22. After the third welding points 601 are formed, the third welding points 601 can play a transition role. When the roller enters the curved rail, the roller will first contact the third welding points 601, and the number and spacing of the third welding points 601 are set to enable the roller to pass through the third welding points more smoothly.

[0095] By adopting the above technical solution, through the fine processing of the third welding points at the two ends, the edge fixing quality of the inner lining sheet is optimized. The number and spacing of the welding points are accurately calculated according to the width information of the inner lining sheet, and micro welding is performed. This method can ensure the firm fixing of the end part of the inner lining sheet while protecting the mechanical properties of the material, so that the inner lining sheet can more durably and stably play its role of enhancing the deformation resistance of the curved rail. Moreover, the third welding points play a transition role, so that the roller can pass through the third welding points to enter the curved rail, so that the running effect of the curved rail is better.

[0096] In the following embodiments, after the third welding points are formed, in order to ensure the smoothness of the bent outer side of the first sheared curved rail, the third welding points also need to be polished to ensure the smoothness. Therefore, the present embodiment discloses a polishing method of third welding points. Please refer to Figure 7 The method comprises the following steps. Step S701: obtaining a morphological image of the third welding points.

[0097] The morphological image refers to an image including the third weld points. For example, the third weld points are photographed by using a camera to obtain the morphological image.

[0098] In step S702, morphological information of the third weld points is obtained according to the morphological image, and the morphological information includes position information and contour information of the third weld points.

[0099] The position information is used to describe the positions of the third weld points at the two ends of the inner liner.

[0100] The contour information is used to describe the edge shape of the third weld points.

[0101] For example, edge lines of the third weld points are obtained by using an edge detection algorithm. The contour information is generated based on the edge lines. Further, the center of gravity of the third weld points is generated according to the aforementioned contour information. The position information is obtained according to the position of the center of gravity.

[0102] In step S703, an S-shaped polishing path is set according to the morphological information.

[0103] For example, an initial polishing path is generated according to the position information, and the initial polishing path passes through each third weld point and is in an S shape. A polishing radius is obtained. An initial polishing area is generated according to the polishing radius and the initial polishing path, and the shortest distance from the edge of the initial polishing area to the initial polishing path is the polishing radius. The initial polishing path is adjusted according to the initial polishing area and the contour information to obtain an S-shaped polishing path, so that the S-shaped polishing path corresponds to a polishing area covering each third weld point.

[0104] In step S704, the third weld points are polished according to the S-shaped polishing path.

[0105] For example, the first shearing rail is placed on a polishing device. A polishing cutter on the polishing device is controlled to be aligned with the positions of the two ends of the inner liner. The polishing cutter is controlled to polish the third weld points along the S-shaped polishing path.

[0106] By using the above technical solution, an intelligent polishing scheme is provided for the third weld points on the inner liner. By obtaining the morphological image of the weld points and setting the S-shaped polishing path accordingly, efficient and accurate processing of the contour of the weld points is realized. This fine polishing can completely eliminate the sharp protrusions and burrs of the weld points and form a smooth transition. The direct benefit is to avoid stress concentration at the weld point position, and stress concentration is the root cause of the initiation of fatigue cracks when the rail is subjected to alternating loads. Therefore, this scheme not only improves the aesthetic appearance of the inner liner area, but also essentially reduces the risk of early failure of the rail due to stress concentration at the inner liner weld point, prolonging the overall service life of the rail after strengthening.

[0107] In the following embodiments, when fixing the inner liner, the fit degree of the inner liner and the first shear bending rail needs to be considered to determine whether the inner liner can be fixed on the first shear bending rail. If the fit degree of the inner liner and the first shear bending rail is poor, the process of welding the inner liner to the first shear bending rail will be affected, resulting in poor welding effect. Therefore, the present application discloses a detection method of an inner liner. Referring to Figure 8 The method comprises: Step S801: detecting an actual curvature of the inner liner.

[0108] For example, the curvature meter is used to measure the inner liner to obtain the actual curvature. For example, the three-dimensional scanner is used to scan the inner liner to obtain a digital model of the inner liner. The actual curvature is obtained through the digital model.

[0109] Step S802: in the case that the actual curvature is greater than the preset curvature, and the difference between the actual curvature and the preset curvature is greater than the preset curvature difference, after the first welding point is formed at the center position, a temporary welding point is determined on the inner liner, and the distance from the temporary welding point to the center position is a preset distance.

[0110] The preset curvature is a preset empirical value, which is used to represent the ideal curvature of the inner liner. For example, the ideal curvature is the liner processing curvature described above.

[0111] The distance from the temporary welding point to the center position refers to the distance value from the temporary welding point to the center position along the curved surface of the inner liner. The temporary welding point is located at the edge position of the inner liner, and the preset distance is a preset empirical value, for example, the preset distance is 30% of the length of the first shear bending rail.

[0112] Step S803: forming a fourth welding point at the temporary welding point.

[0113] For example, the first shear bending rail with the inner liner welded thereon is placed on the welding device. The welding head on the welding device is controlled to be aligned with the temporary welding point.

[0114] Step S804: detecting the fit degree of the inner liner and the first shear bending rail.

[0115] For example, a target point is determined on the surface of the inner liner close to the first shear bending rail, and the target point is located at any position on the inner liner. The shortest distance from the target point to the first shear bending rail is obtained. The target point is updated and the shortest distance is repeatedly obtained to form a set of shortest distances. The median of the shortest distances in the set of shortest distances is calculated, and the median is used to represent the fit degree.

[0116] Step S805: in the case that the fit degree meets the preset standard, the step of forming the second welding point at the edge position of the inner liner along the path from the center position to the two end positions is continued.

[0117] In some other embodiments, in the case where the degree of fit does not meet the preset standard, the inner lining sheet needs to be removed from the first shearing bending rail and re-bent.

[0118] By adopting the above technical solution, when it is detected that the actual curvature of the inner lining sheet deviates greatly from the preset value, the fourth welding point is added behind the center welding point to actively and locally correct the shape of the inner lining sheet, so that it better fits the bending outside of the bending rail. After confirming that the degree of fit meets the standard, subsequent welding is continued, and this process ensures that there is no internal stress caused by forced assembly between the inner lining sheet and the bending rail. This enables the inner lining sheet to be finally fixed in the most ideal contact state, thereby maximizing its load-bearing efficiency as a reinforcing component and ensuring the consistency and reliability of the reinforcing effect of the inner lining sheet in each bending rail.

[0119] The embodiments of the present application disclose an adjusting method for manufacturing a bending rail. Referring to Figure 9 , the method comprises: Step S901: acquiring current size information of the bending rail.

[0120] The current size information comprises at least one of the length, the width, the weight and the bending angle of the bending rail.

[0121] Step S902: acquiring historical size information of the last bending rail.

[0122] The last bending rail refers to the bending rail obtained in the last production.

[0123] The historical size information comprises at least one of the length, the width, the weight and the bending angle of the last bending rail.

[0124] Step S903: calculating the difference between the current size information and the historical size information to obtain a size difference.

[0125] The size difference refers to the difference between the value corresponding to the current size information and the value corresponding to the historical size information.

[0126] Step S904: if the size difference is greater than a preset size difference threshold, adjusting the manufacturing parameters of the next bending rail according to the size difference.

[0127] The manufacturing parameters refer to adjustable variables used by the manufacturing execution equipment when processing the bending rail. Adjusting the manufacturing parameters can directly affect the size of the final bending rail. Exemplarily, the manufacturing parameters comprise at least one of the bending angle, the heating temperature, the heating time, the pressing pressure and the pressing rate.

[0128] The preset size difference threshold is a preset empirical value.

[0129] In some other embodiments, if the size difference is not greater than a preset size difference threshold, the manufacturing parameter is maintained unchanged.

[0130] By adopting the technical solution, the consistency of the reinforcing effect of the inner lining is indirectly but systematically ensured by monitoring and adjusting the size information of the bent rail. Fluctuation of the size of the bent rail directly affects the curvature and shape of the bent outer side, so that the prefabricated inner lining cannot achieve optimal fitting. By calculating the difference between the current and historical sizes and automatically adjusting the subsequent manufacturing parameters when the threshold is exceeded, the scheme can control the machining precision of the bent rail body from the source. This ensures that the bent outer side geometry of each bent rail is stable within the expected range, thereby creating a prerequisite for the accurate and effective fixation of the inner lining, and ensuring the repeatability of the inner lining reinforcement process and the quality uniformity of the final product as a whole.

[0131] Based on the same inventive concept, an embodiment of the present application provides a bent rail manufacturing system, please refer to Figure 10 The system comprises: An acquisition module 1001 is configured to acquire a cutting size of the bent rail and a design size of the bent rail. A memory 1002 is configured to store a program of the bent rail manufacturing method. A processor 1003, the program in the memory can be loaded and executed by the processor and implement the bent rail manufacturing method.

[0132] By adopting the technical solution, the structure rigidity and anti-deformation ability of the bent rail at the bending position, which is a key stress position, are significantly enhanced by fixing the inner lining on the bent outer side of the first cut bent rail. The bent outer side is most prone to elongation and fatigue damage under stress, and the inner lining as a reinforcing component effectively disperses the stress borne by the area and suppresses the deformation tendency of the rail. Subsequent polishing of the inner lining eliminates surface burrs and unevenness, which not only reduces friction and interference when assembling with subsequent positioning pieces or other components, but also ensures the tightness of the bent rail assembly, thereby improving the overall structural stability and service life of the final product.
