Description

Technical Field

[0001] The present invention relates to the technical field of steel structures, and in particular to a laser cutting method, device, electronic equipment and medium for three-dimensional five-axis steel sections. Background Art

[0002] Currently, steel structure production typically relies on manual and mechanical cutting. Manual cutting is time-consuming and unsafe, resulting in unstable slopes and requiring subsequent polishing. Mechanical processing typically involves plasma, laser, and sawing. Plasma cutting consumes a lot of energy and has limited slopes. Saws process a single component and are inefficient, leading to the use of laser processing.

[0003] Laser processing involves thermal processing. At the corners of steel sections, the typical processing method involves moving the web toward the flange, with the axis of rotation near the corner. This increases the wall thickness due to the axis of rotation, and the flanges are often cut in the same area at the corners. Due to current equipment calibration and laser power limitations, this can result in steps or textures at the corners. Summary of the Invention

[0004] In view of this, it is necessary to provide a three-dimensional five-axis laser cutting method, device, electronic equipment and medium for steel sections to solve the technical problem of steps or textures appearing at the corners when the existing laser processing method is used to process steel sections.

Based on the processing file, the laser cutting machine is controlled to perform U-groove tool path cutting on the inner side of the web of the three-dimensional five-axis steel section, and to cut the wing plate by half-side processing according to the target angle.

[0017] In one possible implementation, based on the processing file, a laser cutting machine is controlled to perform a U-groove tool path cutting on the inner side of the web of the three-dimensional five-axis steel section, and to perform half-side processing on the flange according to the target angle, including:

[0018] Based on the processing file, control the laser cutting machine to cut the inner side of the web of the three-dimensional five-axis steel section in the direction from the inner side of the upper edge of the flange to the inner side of the middle of the flange as a first tool path, and cut according to a mirror image tool path of the first tool path;

[0019] Based on the processing file, the laser cutting machine is controlled to cut the wing panel of the three-dimensional five-axis steel section in the direction from the outer side surface of the middle part of the wing panel to the outer side surface of the lower edge of the wing panel as the second tool path, and to cut according to the mirror tool path of the second tool path.

[0020] In a possible implementation, cutting from the inner side of the upper edge of the wing panel to the inner side of the middle of the wing panel is performed as the first tool path, including:

[0021] The direction from the inner side of the upper edge of the wing panel to the inner side of the middle of the wing panel is used as the first tool path for cutting, and the corner position between the inner side of the upper edge of the wing panel and the inner side of the middle of the wing panel is cut according to a quarter arc.

By controlling the laser cutting machine to perform a U-groove tool path on the inner side of the web and half-side machining of the flange at an angle, the present invention avoids the gradual swing axis and the repeated machining of the flange at the corner of the web, thereby achieving the effect of removing steps and smoothing the slope texture. In addition, when laser machining the flange, a certain angle is formed between the cutting gun of the laser cutting machine and the flange, allowing the molten iron of the steel to flow away, avoiding the accumulation and solidification of the molten iron at the corner to form steps, thereby solving the technical problem of steps or textures at the corner when machining steel using existing laser machining methods. Compared to other laser processing paths, the present invention offers superior and more ideal processing results. It eliminates the need for subsequent polishing and other processing steps, enabling rapid production and possessing significant practical significance in the field of steel structures. Furthermore, while conventional laser processing paths are horizontal, the present invention's path is angled downward, preventing the laser from pointing directly at people, making the laser processing process safer.

[0050] S104. Based on the spatial position of the machining tool path, the machining posture and the safety point, control the laser cutting machine to perform U-groove tool path cutting on the inner side of the web of the three-dimensional five-axis steel section, and to perform half-side machining on the wing plate according to the target angle.

[0051] It is understood that the three-dimensional five-axis laser cutting method for steel sections provided by the present invention is a method for automatically generating a vertical machining path for the steel section based on the geometric dimensions of the drawing. By performing U-groove machining on the inner side of the web and half-side machining of the wing with an angle, it avoids the repeated machining of the gradual swing axis and wing at the corner of the web, thereby removing steps and achieving a smooth slope texture.

[0056] (5) The calculated machining tool path is converted into a machining file that can be recognized by the machine. The machining file contains information such as machining tool path, process settings (laser power and other processes), automatic positioning, etc.

[0057] (6) Import the converted processing files into the equipment system and drive the equipment to perform automated production and processing.

[0058] This invention utilizes a U-groove process on the web and lower half of the flange of a three-dimensional, five-axis steel profile, achieving vertical processing of the steel, resulting in step-free corners and smooth textures. Compared to other laser processing paths, this method offers superior and more ideal results, eliminating the need for subsequent polishing and other processing steps, enabling rapid production and significant practical significance in the steel structure industry.

[0061] The geometric information of the three-dimensional five-axis steel section in the plane image is identified to obtain the geometric information of the three-dimensional five-axis steel section.

[0062] It is understandable that the drawings are standard three-dimensional five-axis steel drawings, which generally support NC1 files under TEKLA, STEP, and DXF three-view plane drawings.

[0063] In some embodiments, the geometric information includes: width, height, flange thickness, web thickness, and corner radius of the three-dimensional five-axis steel section.

[0064] In some embodiments, based on the spatial position of the machining tool path, the machining posture, and the safety point, controlling the laser cutting machine to perform a U-groove tool path cutting on the inner side of the web of the three-dimensional five-axis steel section, and performing half-side machining on the wing panel according to the target angle, includes:

[0065] Determining a machining path for a three-dimensional five-axis steel section based on the spatial position of the machining path, the machining posture, and the safety point;

[0066] The processing tool path is converted into a processing file that can be recognized by the laser cutting machine. Based on the processing file, the laser cutting machine is controlled to perform U-groove tool path cutting on the inner side of the web of the three-dimensional five-axis steel section, and to cut the wing plate by half-side processing according to the target angle.

[0067] It can be understood that based on the processing file, the laser cutting machine is controlled to perform U-groove tool path cutting on the inner side of the web of the three-dimensional five-axis steel section, and to perform half-side processing on the wing plate according to the target angle. The web plate can be cut first and then the wing plate, or the wing plate can be cut first and then the web plate.

[0068] In some embodiments, controlling a laser cutting machine to perform a U-groove tool path cutting on the inner side of the web of a three-dimensional five-axis steel section based on the processing file, and cutting the flange in a half-side processing manner according to a target angle, includes:

[0069] Based on the processing file, control the laser cutting machine to cut the inner side of the web of the three-dimensional five-axis steel section in the direction from the inner side of the upper edge of the flange to the inner side of the middle of the flange as a first tool path, and cut according to a mirror image tool path of the first tool path;

[0070] Based on the processing file, the laser cutting machine is controlled to cut the wing panel of the three-dimensional five-axis steel section in the direction from the outer side surface of the middle part of the wing panel to the outer side surface of the lower edge of the wing panel as the second tool path, and to cut according to the mirror tool path of the second tool path.

[0071] It can be understood that the zero point position is based on the center of the steel boxbound as the reference, the spatial position (x, y, z).

[0072] refer to Figure 2 The long direction of the steel section is the X direction, the wide direction of the steel section is the Y direction, the high position of the steel section is the Z direction, and Y+ is defined as the positive direction of the Y axis, and Y- is defined as the negative direction of the Y axis.

[0073] Wing plate Y+ tool path: the outer side of the middle of the wing plate P1 = (0, w 0.5,wt), the height direction of P1 can be set, and it can be fine-tuned up and down at the current position. The outer side of the lower edge of the wing plate P2=(0,w 0.5,-h 0.5). The cutting gun posture is adjustable, and the general gun angle is 45 degrees. P1 and P2 are connected to form a wing plate processing tool path.

[0074] Wing plate Y-path: outer side of the middle of the wing plate P3 = (0, -w 0.5, wt), the height direction of P3 can be set, and fine adjustment can be made up and down at the current position. The outer side of the lower edge of the wing plate P4 = (0, -w 0.5,-h 0.5). The cutting gun posture is adjustable, and the general gun angle is 45 degrees. P3 and P4 are connected to form a wing plate processing tool path.

[0075] Web Y+ tool path: inner side of the upper edge of the wing plate P5=(0,w 0.5-t,h 0.5), the inner side of the middle of the wing plate P6=(0,w 0.5-t,wt 0.5 + r); the corner position is realized according to the standard arc, and the points on the arc are obtained to form continuous processing points Pyps. At the same time, the posture is fixed; the middle position of the web P7 = (0, 0, wt*0.5), the cutting gun posture is opposite to the outer side of the wing plate, and these points P5, P6, Pyps, P7 are connected to form a processing tool path.

[0076] Web Y-path: It is a mirror image of the Y+path and processes the other side.

[0077] In some embodiments, cutting in a direction from the inner side of the upper edge of the wing panel to the inner side of the middle portion of the wing panel as a first tool path includes:

[0078] The direction from the inner side of the upper edge of the wing panel to the inner side of the middle of the wing panel is used as the first tool path for cutting, and the corner position between the inner side of the upper edge of the wing panel and the inner side of the middle of the wing panel is cut according to a quarter arc.

[0079] It can be understood that the corner position is realized according to a standard arc, which is a quarter arc. Through trigonometric functions, the Y-axis coordinate and the Z-axis coordinate are calculated by multiplying the radius by the angle for every 5 degrees to obtain the points on the arc and form continuous processing points Pyps.

[0080] In some embodiments, the target angle is the angle between a cutting gun of a laser cutting machine and the wing panel, and the target angle ranges from 30 to 75 degrees.

[0081] It is understandable that the target angle may be 45 degrees, 30 degrees or 75 degrees.

[0082] In some embodiments, the present invention provides a method for laser cutting of a three-dimensional five-axis steel section, comprising:

[0083] Step 1: Using the imported drawing, use the feature recognition algorithm:

[0084] Get the geometric information of the drawing, including the width (w), height (h), flange thickness (t), web thickness (wt), and corner radius (r) of the profile.

[0085] Step 2: Calculate the machining path of the steel U-groove:

[0086] The zero point position is based on the center of the steel boxbound, spatial position (x, y, z).

[0087] refer to Figure 2 The long direction of the steel section is the X direction, the wide direction of the steel section is the Y direction, the high position of the steel section is the Z direction, and Y+ is defined as the positive direction of the Y axis, and Y- is defined as the negative direction of the Y axis.

[0088] Wing plate Y+ tool path: the outer side of the middle of the wing plate P1 = (0, w 0.5,wt), the height direction of P1 can be set, and it can be fine-tuned up and down at the current position. The outer side of the lower edge of the wing plate P2=(0,w 0.5,-h 0.5). The cutting gun posture is adjustable, and the general gun angle is 45 degrees. P1 and P2 are connected to form a wing plate processing tool path.

[0089] Wing plate Y-path: outer side of the middle of the wing plate P3 = (0, -w 0.5, wt), the height direction of P3 can be set, and fine adjustment can be made up and down at the current position. The outer side of the lower edge of the wing plate P4 = (0, -w 0.5,-h 0.5). The cutting gun posture is adjustable, and the general gun angle is 45 degrees. P3 and P4 are connected to form a wing plate processing tool path.

[0090] Web Y+ tool path: inner side of the upper edge of the wing plate P5=(0,w 0.5-t,h 0.5), the inner side of the middle of the wing plate P6=(0,w 0.5-t,wt 0.5 + r); the corner position is realized as a standard arc, which is a quarter arc. Through trigonometric functions, at every 5-degree angle, the Y-axis coordinates and Z-axis coordinates are calculated by multiplying the radius by the angle to obtain the points on the arc, forming continuous processing points Pyps. At the same time, the posture is fixed; the middle position of the web P7 = (0, 0, wt*0.5), the cutting gun posture is opposite to the outer side of the wing plate, and these points P5, P6, Pyps, and P7 are connected to form a processing tool path.

[0091] Web Y-path: It is a mirror image of the Y+path and processes the other side.

[0092] Step 3: Processing tool path sequence:

[0093] There are two types, one is to process the wing plate first and then the web plate, such as Figure 3 Another method is to process the web first and then the wing plate, as shown in Figure 4 When machining the flange, first locate the machining point on the upper half of the flange and work from top to bottom. When machining the web, first start from the inner side of the upper half of the flange and work from top to bottom until you reach the center of the web.

[0094] Step 4: Assign the machining toolpath to the nesting code and proofing code:

[0095] According to the data of step 2, the data of the tube length direction is assigned to detect whether there is a vertical cut in the part. If there is a vertical cut, the processing tool path of the vertical cut is assigned according to step 2 to realize the generation of the processing tool path.

[0096] Step 5: Output the calculated processing code as a processing file:

[0097] The system implements protocol constraints, converts the spatial coordinates and posture of the machining toolpath into a machining file, and performs data flow conversion and output. The machining file contains the planned machining toolpath and process information, which is directly placed on the 3D 5-axis machine for actual machining.
