Description

Background Art

[0002] With the development of economy, infrastructure construction is increasing. Steel, which has the advantages of high strength, light weight and environmental protection, is one of the main structural materials of infrastructure construction, and its demand is also increasing.

[0061] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] In order to solve the above problems, a steel cutting method provided in an embodiment of the present application will be introduced and explained in detail through the following specific embodiments.

[0063] Reference Figure 1 , showing a schematic flow chart of a steel cutting method provided by an embodiment of the present invention.

[0064] In one embodiment, the method is applicable to a control terminal of a steel cutting system. By controlling the cutting tool of the steel cutting system to perform cutting processing through the control terminal, errors can be reduced and cutting accuracy can be improved.

[0065] Wherein, as an example, the steel cutting method may include:

[0066] S11. Acquire process data of the steel to be processed after the steel to be processed is placed on the placement platform, wherein the process information is data on the overall size of the steel to be processed and the size of the finished product.

[0067] In one embodiment, the steel material cutting system is provided with a placement platform for placing the steel material to be processed. A clamp may be provided on the placement platform for fixing the steel material to be processed.

[0068] In one implementation, a technician may place the steel material to be processed on a placement platform, and then clamp the steel material with a clamp so that the steel material may be fixed on the placement platform.

[0069] When the steel is placed stably, the process data of the steel to be processed can be obtained, which can be data about the overall size of the steel to be processed and the size of the finished product, for example, the length, width, height and thickness of the steel to be processed, and can also include the length, width, height and thickness of the steel after cutting.

[0070] S12. After determining the cutting type based on the process data, call the corresponding cutting tool according to the cutting type to perform the first cutting on the steel to be processed and obtain a real-time image of the steel to be processed, wherein the real-time image is an image taken during the first cutting process of the steel to be processed.

[0071] Since different sizes are suitable for different cutting types, the present invention can use different types of cutting methods for different sizes, thereby reducing cutting errors and improving cutting accuracy.

[0072] After determining the cutting type, the corresponding cutting tool can be called according to the cutting type to perform the first cutting of the steel to be processed. For example, if the steel is thick, the cutting type can be flame cutting, and a flamethrower can be used to generate a high-temperature flame to cut the steel. For another example, if the steel is thin, the cutting type can be laser cutting, and the steel can be cut using the high energy generated by the focused laser beam.

[0073] During the cutting process, the steel may have position deviation due to the looseness of the tool clamp, or the steel itself may be deformed. In order to correct the deviation, a real-time image of the steel to be processed can be obtained. The real-time image is an image taken during the first cutting process of the steel to be processed. For example, when the cutting tool is called to start the first cut, the image of the steel is taken in real time. Subsequently, the real-time image can be used to determine whether the steel has deviations, and cutting adjustments and corrections can be made based on the deviations, thereby improving the cutting accuracy.

[0074] Optionally, the real-time image can be shot from different angles, such as from a frontal overlooking angle or from a side left perspective.

[0075] In an optional embodiment, the process data includes: the overall size value of the steel material and the finished product size value required after the steel material is cut.

[0076] Specifically, the overall size value of the steel material is the length, width, height and thickness of the steel material to be processed that is currently fixed on the placement platform. The finished product size value is the length, width, height and thickness of the steel block after cutting. For example, if the steel material to be processed is a rectangular parallelepiped steel material, the overall size value is the length, width, height and thickness of the rectangular parallelepiped. If the finished product after cutting is a cube, the finished product size value is the length, width, height and thickness of the cube.

[0077] In one implementation, a technician can place the steel to be processed on a placement platform and upload the overall size value and the finished product size value to a control terminal. In another optional embodiment, a camera can be called to shoot the steel to be processed, and the overall size value of the steel to be processed can be obtained by identifying the image of the steel to be processed. The specific identification can adopt a conventional recognition algorithm.

[0078] Wherein, as an example, determining the cutting type based on the process data may include the following sub-steps:

[0079] S121. If the overall size value is greater than a preset size threshold or the finished product size value is greater than a preset finished product value, it is determined that the cutting type is flame cutting.

[0080] S122: If the overall size value is smaller than a preset size threshold and the finished product size value is smaller than a preset finished product value, determine that the cutting type is laser cutting.

[0081] Specifically, the user can pre-set different thresholds to respectively determine whether the overall size value and the finished product size value are greater than the corresponding thresholds.

[0082] If the overall size value is greater than the preset size threshold, or the finished product size value is greater than the preset finished product value, it means that the steel to be processed is thicker or the steel after cutting is thicker. If laser cutting is used, it will take a long time and cost a lot. It can be determined that the cutting type is flame cutting.

[0083] If the overall size value is smaller than the preset size threshold, and the finished product size value is smaller than the preset finished product value, it means that the steel to be processed is thin and the finished product after cutting is small, laser cutting can be used, and the cutting type can be determined to be laser cutting.

[0084] In another optional embodiment, the process data may also include: a finished product error value or a finished product precision value, which may specifically be an acceptable deviation value of the finished steel product after cutting.

[0085] It can be determined whether the error value of the finished product is greater than the preset error value. If the error value of the finished product is greater than the preset error value, the cutting type is determined to be flame cutting. Conversely, if the error value of the finished product is less than the preset error value, the cutting type is determined to be laser cutting. The preset error value is the average error value of flame cutting.

[0086] S13. Determine a cutting offset value of the steel to be processed according to the real-time image, wherein the cutting offset value is a value of deviation generated during the first cutting process of the steel to be processed.

[0087] When starting the first cut, the real-time image can be identified. By identifying the position and shape of the steel to be processed in the real-time image, it can be determined whether the steel to be processed has been deformed or offset. If the steel to be processed has been deformed or offset, the offset value caused by the deformation or position deviation can be calculated based on its position and deformed shape to obtain the cutting offset value. Subsequently, it can be determined whether the cutting method needs to be modified or the cutting size needs to be adjusted based on the cutting offset value, so that the finished product after cutting can meet the requirements, thereby reducing deviations and improving accuracy.

[0088] In one embodiment, the step of determining the cutting offset value of the steel material to be processed according to the real-time image may include the following sub-steps:

[0089] S21. If the real-time image is an image taken from the front, extract a plurality of first image frames from the real-time image at a preset first time interval.

[0090] S22, respectively obtaining the coordinates of the two first endpoints of the steel material to be processed in each of the first image frames, and determining the position connection line corresponding to each of the first image frames using the coordinates of the two first endpoints.

[0091] S23, calculating the angle between the position line of each of the first image frames and a preset initial line to obtain a cutting offset value related to the position change, wherein the preset initial line is a line connecting two end points detected after the steel to be processed is placed on the placement platform.

[0092] In one embodiment, the real-time image may be taken from a frontal overlooking angle, and the steel material photographed from the frontal overlooking angle can be used to determine whether the steel material has position deviations due to flame jetting during the cutting process.

[0093] Since the real-time image has multiple image frames, it takes a long time to process each image frame. When the real-time image is a frontal image, several first image frames can be extracted from the real-time image according to a preset first time interval. The several first image frames are identified to determine whether the position of the steel is deviated.

[0094] Optionally, the preset first time interval may be 1 millisecond or 0.5 millisecond, and may be adjusted according to actual needs.

[0095] Next, the coordinates corresponding to the two endpoints of the steel material to be processed in each first image frame can be obtained respectively to obtain the coordinates of the two first endpoints.

[0096] For example, if the steel material to be processed is a rectangular parallelepiped steel material, the coordinates of the lower left corner and the lower right corner of the steel material to be processed can be obtained to obtain the coordinates of the two first endpoints.

[0097] For another example, the coordinates of the upper left corner and the upper right corner of the steel material to be processed may be acquired to obtain the coordinates of the two first endpoints.

[0098] For another example, the coordinates of the upper right corner and the lower right corner of the steel material to be processed may be acquired to obtain the coordinates of the two first endpoints.

[0099] Optionally, if the steel material to be processed is a polygon, the coordinates of any two endpoints of the steel material to be processed may be acquired to obtain the coordinates of two first endpoints.

[0100] Next, the position line corresponding to each first image frame can be determined using the two first endpoint coordinates. Specifically, the two endpoint coordinates can be used to construct a line to obtain the position line.

[0101] After calculating the position line, the position line of each first image frame can be obtained. Then, the angle between the position line of each first image frame and the preset initial line can be calculated to obtain the cutting offset value related to the position change, wherein the preset initial line is the line of the two end points detected after the steel to be processed is placed on the placement platform.

[0102] For example, if the steel material to be processed is a rectangular parallelepiped steel material, the preset initial connection line is a connection line formed by the coordinates of the upper left corner and the upper right corner of the steel material to be processed. Similarly, the position connection line of each first image frame is a connection line formed by the coordinates of the upper left corner and the upper right corner of the steel material to be processed.

[0103] Then, calculations can be made one by one in the order of extracting the first image frames. First, the angle between the position line of the first first image frame and the preset initial line is calculated to obtain the cutting offset value corresponding to the first first image frame; then the angle between the position line of the second first image frame and the preset initial line is calculated to obtain the cutting offset value corresponding to the second first image frame.

[0104] A subsequent judgment is then performed based on the cutting offset value corresponding to each first image frame to determine whether cutting adjustment is required.

[0105] Optionally, after calculating a plurality of cutting offset values, they may be summed and averaged, and then subsequent judgment may be performed based on the average value of the cutting offset values.

[0106] For example, the number is set to 10. After 10 cutting offset values ​​are calculated continuously, the 10 cutting offset values ​​are summed and averaged to obtain the average value of the cutting offset value, and then subsequent judgment is made based on the average value of the cutting offset value to determine whether cutting adjustment is required.

[0107] In one embodiment, the step of determining the cutting offset value of the steel material to be processed according to the real-time image may include the following sub-steps:

[0108] S31: If the real-time image is an image taken from the side, extract a plurality of second image frames from the real-time image at a preset second time interval.

[0109] S32, obtaining the coordinates of the tail end of the steel material to be processed in each of the second image frames to obtain the second endpoint coordinates.

[0110] S33, using each of the second endpoint coordinates to calculate the height between the steel material to be processed and the placement platform, to obtain a cutting offset value related to the shape change.

[0111] In one embodiment, the real-time image may be taken from a side left perspective, and whether the steel is bent or deformed can be observed from the side. For example, the steel to be processed is a rectangular parallelepiped steel, and when the left end of the steel is cut, the right side of the steel is tilted and deformed.

[0112] Since the real-time image has multiple image frames, it will take a long time to process each image frame. Referring to the above analysis, in one embodiment, when the real-time image is an image taken from the side, several image frames can be extracted from the real-time image according to a preset second time interval to obtain several second image frames. Then, the several second image frames are identified to determine whether the steel is deformed.

[0113] Optionally, the preset second time interval may be 1 millisecond or 0.5 millisecond, and may be adjusted according to actual needs.

[0114] The deformation of steel is generally bending deformation, and the coordinates of the tail end of the steel to be processed in each second image frame can be obtained to obtain the coordinates of the second endpoint. For example, the steel to be processed is a rectangular steel, which is cut from left to right to be cut into multiple cubic steel blocks. When cutting on the left side, the coordinates of the endpoint on the right side can be detected to obtain the coordinates of the second endpoint.

[0115] Then, the second endpoint coordinates can be used to calculate the spacing height between the steel material to be processed and the placement platform to obtain a cutting offset value related to the shape change.

[0116] If the steel to be processed is bent or warped, its tail end will rise when one end is fixed, so that the tail of the steel will be separated from the flat placement platform. The height of the separation can be calculated to obtain the cutting offset value related to the change in the shape of the steel to be processed.

[0117] S14: When the cutting offset value is greater than a preset offset threshold, performing a second cutting based on the cutting offset value.

[0118] After obtaining the cutting offset value related to the shape change of the steel material to be processed or the cutting offset value related to the position change of the steel material to be processed, it can be determined whether the cutting offset value is greater than the preset offset threshold. If the cutting offset value is greater than the preset offset threshold, it means that the shape change or position change of the steel material to be processed is large. At this time, it needs to be adjusted, and the current first cutting can be terminated, and then the second cutting can be performed again.

[0119] Similarly, if the cutting offset value is less than the preset offset threshold, it means that the shape or position change of the steel to be processed is small, and the error caused by the change is acceptable. At this time, no adjustment is made and the first cutting can be continued.

[0120] It should be noted that if a second cutting is required, the current first cutting can be stopped, and then the second cutting can be performed according to the cutting offset value to reduce the cutting error and improve the cutting accuracy.

[0121] In one embodiment, the cutting offset value is a value related to the position change of the steel to be processed. In order to adjust for the position change of the steel, as an example, the second cutting based on the cutting offset value may include the following sub-steps:

[0122] S41. If the cutting offset value is a cutting offset value related to position change, determine the distance value from the current cutting coordinate point of the steel to be processed to the edge of the steel to be processed, and the edge of the steel to be processed is the edge in the direction of the angle value corresponding to the cutting offset value.

[0123] S42. If the distance value is greater than the finished product size value, the current cutting coordinate point is used as the first cutting starting point, and the corresponding cutting tool is called according to the cutting type to perform a second cutting on the steel to be processed at the first cutting starting point.

[0124] If the cutting offset value is the cutting offset value related to the position change, it means that the steel may have a deviation in position due to vibration or looseness during cutting. If cutting is continued at this time, the finished product will have a large deviation, and resources and time will be wasted. In order to make adjustments in time, the cutting position of the cutting tool on the steel to be processed can be determined at this time to obtain the current cutting coordinate point.

[0125] After determining the current cutting coordinate point, the angle value direction corresponding to the cutting offset value can be determined, and then the distance value from the current cutting coordinate point along the angle value direction to the edge of the steel to be processed can be determined.

[0126] After determining the current cutting coordinate point, the cutting direction of the cutting tool at this time can also be determined, and then the distance value from the current cutting coordinate point along the cutting direction of the cutting tool to the edge of the steel to be processed is determined.

[0127] If the distance value is greater than the finished product size value, it means that the current cutting coordinate point is used as the starting point and the cutting is continued in the current direction to obtain a finished product that meets the requirements. At this time, the current cutting coordinate point can be used as the first cutting starting point, and the corresponding cutting tool can be called according to the current cutting type to re-cut the steel to be processed at the first cutting starting point for the second time.

[0128] In a preferred embodiment, after determining that the distance value is greater than the finished product size value, a prompt message can be sent to the technician, and then the technician can check that the steel to be processed is re-fixed before starting the second cutting to improve the cutting accuracy.

[0129] In one embodiment, the cutting offset value is a value related to the change in the shape of the steel to be processed. In order to adjust for the deformation of the steel, as an example, the second cutting based on the cutting offset value may include the following sub-steps:

[0130] S51: If the cutting offset value is a cutting offset value related to morphological change, adjust the cutting type and determine a second cutting starting point based on the cutting offset value.

[0131] S52: Based on the adjusted cutting type, a corresponding cutting tool is called to perform a second cutting on the steel material to be processed at the second cutting starting point.

[0132] Specifically, if the cutting offset value is a cutting offset value related to deformation, it means that the steel has deformed during the cutting process and the current cutting type cannot withstand it. If you continue cutting at this time, not only will the finished product have a large deviation, but the steel will continue to deform. It may be impossible to cut due to the large deformation. The structure of the steel needs to be modified before cutting can continue, which increases the subsequent processing steps and reduces the processing efficiency. In order to make adjustments in time, the cutting type can be adjusted. For example, if the current cutting type is flame cutting, it can be changed to laser cutting; similarly, if the current cutting type is laser cutting, it can be changed to flame cutting.

[0133] After the cutting type is modified, the starting point of the cutting can be re-determined to obtain a second cutting starting point. The second cutting starting point can be determined based on the cutting offset value.

[0134] Specifically, the cutting offset value is the height value generated by the deformation. The height value can be used as a reference value, and the reference value can be horizontally moved from the end of the steel material, and this can be used as a starting point. At this time, it can be determined whether the distance between this starting point and the edge of the steel material is greater than the finished product size value. If so, this can be used as a starting point and the corresponding cutting tool can be called based on the adjusted cutting type to perform a second cut at the second cutting starting point of the steel material to be processed.

[0135] For example, the steel to be processed is a rectangular steel, and the equipment starts cutting from the left side of the steel. At this time, it is detected that the right side of the steel is tilted, and the cutting offset value related to the shape change is greater than the preset offset threshold.

[0136] The second cutting starting point can be obtained by horizontally moving the tilted height from the right end of the steel. It can be determined whether the distance between this starting point and the edge of the steel is greater than the finished product size value. If the distance between this starting point and the edge of the steel is greater than the finished product size value, the corresponding cutting tool can be used as the starting point and based on the adjusted cutting type to perform a second cut on the steel to be processed at the second cutting starting point.

[0137] Since laser or high-temperature flame may be used during the cutting process, the technicians in the background cannot directly see the cutting situation. In order to facilitate the technicians to view the cutting situation, as an example, after the step of calling the corresponding cutting tool according to the cutting type to perform the first cutting on the steel to be processed and obtaining the real-time image of the steel to be processed, the method further includes:

[0138] The management terminal of the technician is determined, and the real-time image is transmitted to the management terminal for the user to view.

[0139] In specific operations, the control terminal can be connected to the management terminals of different technicians in communication. After acquiring the real-time image, the real-time image can be transmitted to the management terminal for viewing by users or different technicians.

[0140] In this embodiment, an embodiment of the present invention provides a steel cutting method, and its beneficial effects are: the present invention can obtain data on the overall size and finished product size of the steel to be processed after the steel to be processed is placed on the placement platform, call the corresponding cutting tool based on the process data to perform the first cutting on the steel to be processed and obtain the real-time image of the steel to be processed; determine the cutting offset value of the steel to be processed according to the real-time image; when the cutting offset value is greater than the preset offset threshold, perform a second cutting based on the cutting offset value; the cutting deviation can be adjusted through the second cutting, thereby improving the cutting accuracy.
