Description

Technical Field

[0001] This invention relates to the field of laser cutting equipment technology, specifically to a universal laser cutting equipment for adaptive clamping of steel profiles and pipes. Background Technology

[0002] The general-purpose laser cutting equipment for steel pipes is an integrated fiber laser cutting processing equipment that is compatible with round steel pipes. It is mainly used for precision blanking of pipes and profiles in industries such as steel structures, engineering machinery, power transmission towers, and prefabricated buildings. It can replace multiple processes such as traditional sawing, drilling, and beveling, and realize one-time clamping and forming of profiles.

[0003] Traditional processing methods require the combined operation of multiple machines such as sawing machines, drilling machines, beveling machines, and special pipe cutting machines, which results in cumbersome procedures, large transfer errors, large footprint, and high production costs. Meanwhile, the clamping structure of conventional laser cutting equipment has obvious technical defects, making it difficult to meet the needs of profile generalization, high precision, and high efficiency processing.

[0004] Existing laser cutting clamping structures suffer from extremely poor versatility. Traditional three-jaw chucks are only suitable for round tubes, and when clamping irregularly shaped profiles such as angle steel and H-beams, they only achieve single-point contact. During high-speed cutting and rotation, slippage and wobble are prone to occur, resulting in problems such as dimensional deviations and uneven bevels. Specialized steel tooling is mostly a fixed limiting structure, which cannot rotate and cannot achieve three-dimensional intersecting cutting of tubes. It also requires manual adjustment and changeover, which is time-consuming and seriously affects the production efficiency of multi-variety, small-batch orders. At the same time, traditional clamping uses a rigid fixed pressure clamping mode, which easily damages and deforms thin-walled profiles, while heavy thick-walled profiles are prone to shifting due to insufficient clamping force. Furthermore, there is no adaptive follow-up support structure, and long profiles are prone to sagging and shaking during processing, making it difficult to guarantee processing accuracy. In addition, hot-rolled profiles generally have bending and twisting deformations, and traditional rigid clamping cannot adaptively correct or compensate for the cutting trajectory in real time, which can easily lead to finished product assembly deviations. Moreover, the equipment has high waste material and low automation, which restricts production efficiency. Summary of the Invention

[0009] The positioning mechanism includes a mounting block mounted on the multi-row adaptive clamping frame, a positioning roller mounted on the mounting block, a positioning block mounted on the lower pressure frame, a round rod mounted inside the positioning block, and a positioning wheel mounted on the round rod.

[0010] The circumferential surface of the positioning roller is an arc-shaped groove, and a spring is provided between the round rod and the positioning block.

[0011] The general-purpose laser cutting equipment for steel profiles and pipes also includes an anti-collision mechanism installed on the laser device to protect the laser end of the laser device;

[0012] The anti-collision mechanism includes a guide block mounted on the adjusting bracket, a limiting rod mounted on the laser device, an L-shaped rod mounted on the limiting rod, an inclined block mounted on the L-shaped rod, and a protective shell mounted on the side of the L-shaped rod away from the inclined block.

[0013] The L-shaped rod contacts the outer wall of the laser device, a spring is provided between the L-shaped rod and the laser device, the inclined block has an inclined surface, the guide block has an inclined surface, and the inclined block contacts the outer wall of the guide block.

[0014] The general-purpose laser cutting equipment for steel pipes also includes a lifting mechanism installed on the multi-row adaptive clamping frame, which is used to lift the round pipe after processing;

[0015] The lifting mechanism includes a rotating rod mounted on the multi-row adaptive clamping frame, a lifting plate mounted on the rotating rod, a fixing block mounted on the lowering frame, and a pull rod mounted on the fixing block. The rotating rod and the pull rod are hinged together.

[0016] The impurity cleaning mechanism installed on the multi-row adaptive clamping frame of the general-purpose laser cutting equipment for steel profiles and pipes is used to clean impurities in the gaps of the machine tool.

[0017] The impurity cleaning mechanism includes a base plate mounted on the multi-row adaptive clamping frame, a rotating rod mounted inside the base plate, a flipping plate mounted on the rotating rod, a gear mounted on the rotating rod, and a rack mounted on the cutting machine tool.

[0018] The gear meshes with the rack, the flipping plate contacts the outer wall of the cutting machine tool, and the base plate contacts the outer wall of the gear.

[0019] The air-cooling mechanism of the general-purpose laser cutting equipment for steel pipes is installed on the adjusting bracket and is used to air-cool the welded parts when cutting the welded parts.

[0020] The air-cooling mechanism includes an air valve installed on the adjusting bracket, a delivery pipe installed at the output end of the air valve, and an exhaust head installed on the adjusting bracket. The side of the delivery pipe away from the air valve is fixedly installed with the exhaust head.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. In this invention, during the initial stage of operation, multiple rows of round tubes can be placed side by side and enter the interior of a multi-row adaptive clamping frame. At this time, the downward pressure frame moves down to adaptively fix the multiple rows of round tubes on the multi-row adaptive clamping frame, automatically adjusting the clamping distance and clamping force. It flexibly locks the tubes according to the structural characteristics of different profiles, which can not only fix the workpiece to avoid cutting vibration, but also prevent rigid clamping from causing profile deformation. Before adaptive clamping, the positioning roller guides the round tube into the interior of the multi-row adaptive clamping frame. At this time, the downward pressure frame drives the positioning wheel to contact the outer wall of the workpiece, thereby adaptively positioning the workpiece. Through flexible pre-alignment, it automatically corrects the workpiece placement deviation and slight deformation, accurately determines the processing datum, and the flexible buffer positioning method avoids rigid pressure causing workpiece deformation and scratches, while making the subsequent clamping force more uniform.

[0023] 2. In this invention, after the laser device finishes its operation, it rises and resets, causing the limit rod to reset. The inclined block drives the L-shaped rod to retract, and the L-shaped rod moves the protective shell closer to the laser emitting end of the laser device. Thus, the two protective shells are close to protect the laser emitting end of the laser device, extending its service life. This ensures stable laser output and consistent cutting quality, reduces equipment failure rate and maintenance costs, and prevents accidental collisions that could damage the laser head, improving the safety and reliability of continuous operation. After clamping ends, the lower pressure frame pulls the pull rod upward, which in turn moves the rotating rod upward. The rotating rod then moves the lifting plate upward, allowing the lifting plate to support the processed round tube, ensuring the stability of the cutting axis, improving cutting accuracy, preventing tube end wobbling and swinging, reducing vibration, improving cutting quality and safety, ensuring smooth material feeding, preventing workpiece jamming, bumps, and scratches, and improving yield and output efficiency.

[0024] 3. In this invention, after the laser device completes the welding of the workpiece, the multi-row adaptive clamping frame drives the rotating rod to move, and the rotating rod drives the flipping plate to rotate to clean and unclog the internal gaps of the cutting machine tool. This can prevent the accumulation and blockage of molten slag and iron filings, ensure the smooth discharge of smoke and waste, prevent the table from overheating and deforming, ensure the stable operation of subsequent processing, and extend the service life of the equipment. While the laser device is performing laser cutting, the air valve will deliver compressed cold air to the inside of the exhaust head through the delivery pipe. The exhaust head will open the cooling port and aim it at the workpiece being welded for air cooling, which will improve the welding strength and toughness. At the same time, it will prevent the workpiece from overheating and burning, oxidizing and discoloring, improve the appearance quality of the weld, reduce welding stress, reduce the risk of cracking, and improve the stability of the joint.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1:

[0037] Please see Figures 1-4 One embodiment of the present invention is: a universal laser cutting device for adaptive clamping of steel profiles and steel pipes, including a cutting machine tool 1, an electric slide rail 2 fixedly installed on the cutting machine tool 1, an adjusting bracket 3 fixedly installed at the output end of the electric slide rail 2, a laser device 4 fixedly installed on the adjusting bracket 3, and the universal laser cutting device for adaptive clamping of steel profiles and steel pipes further includes an adaptive multi-row clamping mechanism installed on the cutting machine tool 1.

[0038] The adaptive multi-row clamping mechanism includes an electric slide rail 2 5 mounted on the cutting machine tool 1, a multi-row adaptive clamping frame 6 mounted on the output end of the electric slide rail 2 5, a sliding rod 7 mounted on the multi-row adaptive clamping frame 6, a lower pressure frame 8 mounted on the sliding rod 7, a pulley 9 mounted on the lower pressure frame 8, and a guide plate 10 mounted on the cutting machine tool 1. The multi-row adaptive clamping frame 6 contacts the outer wall of the cutting machine tool 1. A guide groove is provided on the guide plate 10. The circumferential surface of the pulley 9 contacts the guide groove of the guide plate 10. The lower pressure frame 8 contacts the outer wall of the multi-row adaptive clamping frame 6, which is used to adaptively clamp multiple rows of round tubes.

[0039] The positioning mechanism of the general-purpose laser cutting equipment for steel sections and pipes, installed on the multi-row adaptive clamping frame 6, is used to position and guide the incoming round steel.

[0040] The positioning mechanism includes a mounting block 11 mounted on a multi-row adaptive clamping frame 6, a positioning roller 12 mounted on the mounting block 11, a positioning block 13 mounted on a lower pressure frame 8, a round rod 14 mounted inside the positioning block 13, and a positioning wheel 15 mounted on the round rod 14.

[0041] The circumferential surface of the positioning roller 12 is an arc-shaped groove, and a spring is provided between the round rod 14 and the positioning block 13.

[0042] In this embodiment, during operation: Initially, the operator imports a specific code into the cutting program via the control terminal according to processing requirements, thus setting the required dimensions, openings, beveling, and other process parameters. After equipment debugging, the operator prepares the profiles. Subsequently, the equipment starts automatic or manual feeding, smoothly conveying the steel pipes to the processing station. To improve cutting efficiency, multiple rows of round pipes can be placed side-by-side. These multiple rows of pipes enter the interior of the multi-row adaptive clamping frame 6. At this time, the control terminal activates the electric slide rail 2 5. The electric slide rail 2 5 moves the multi-row adaptive clamping frame 6 via its moving end. The multi-row adaptive clamping frame 6 moves the sliding rod 7, which in turn moves the lower pressure frame 8. The lower pressure frame 8 and the multi-row adaptive clamping frame 6 synchronously move the round pipes. As the lower pressure frame 8 moves with the multi-row adaptive clamping frame 6, it moves the pulley 9. The pulley 9 slides along the internal guide groove of the guide plate 10. The pulley 9 moves along the guide groove inside the guide plate 10. As the pulley 9 moves downward, it drives the pressure frame 8 downward. The downward movement of the pressure frame 8 adaptively fixes the multiple rows of round tubes on the multi-row adaptive clamping frame 6, automatically adjusting the clamping distance and clamping force. It flexibly locks the profile according to the structural characteristics of different profiles, which can not only fix the workpiece to avoid cutting vibration, but also prevent the profile from being deformed by rigid clamping. At the same time, it completes automatic centering calibration to ensure the accuracy of the processing benchmark. Entering the core clamping and positioning stage, the equipment automatically identifies the cross-sectional specifications, shape deviation and placement position of the profile through the sensor detection module. After the positioning is completed, the terminal system starts the electric slide rail 2 to work. The operation of the electric slide rail 2 will drive the adjustment bracket 3 to adjust through the moving end. The adjustment bracket 3 will drive the laser device 4 to make lateral adjustments during cutting. After the laser device 4 is adjusted to the correct position, it will move downward to improve the alignment accuracy. After the overall adjustment is completed, the laser device 4 will emit laser through the output end to perform laser cutting on the workpiece. Through the servo linkage module, the profile is cut, holed, beveled and other precision processing according to the preset trajectory. During the cutting process, the clamping system provides real-time dynamic compensation to adapt to minute deformations and processing vibrations of the profile, ensuring cutting accuracy. After multiple rows of processing are completed, the follow-up electric slide rail 5 will drive the multi-row adaptive clamping frame 6 to automatically push the profile out through the output end. The multi-row adaptive clamping frame 6 will drive the sliding rod 7 to reset, the sliding rod 7 will drive the lower pressure frame 8 to reset, the lower pressure frame 8 will drive the pulley 9 to reset, and the pulley 9 will reset along with the internal guide groove of the guide plate 10. The pulley 9 will drive the lower pressure frame 8 to automatically open the clamp and perform feeding and cutting again, thereby completing continuous segmented cutting operations. Simultaneously, it completes the cleaning of residue and dust, and operates in a fully automated manner, effectively adapting to the processing of various profiles and significantly improving cutting accuracy and production efficiency.

[0043] Before adaptive clamping, when the multi-row adaptive clamping frame 6 is loaded, the round tube will be guided into the interior of the multi-row adaptive clamping frame 6 by the positioning roller 12. At this time, when the pressing frame 8 presses down, the movement of the pressing frame 8 will drive the positioning block 13 to move. The movement of the positioning block 13 will drive the round rod 14 to move. The movement of the round rod 14 will drive the positioning wheel 15 to contact the outer wall of the workpiece. The positioning wheel 15 will be squeezed and contracted by the workpiece for positioning. The contraction of the positioning wheel 15 will drive the round rod 14 to move. The movement of the round rod 14 will compress the spring between the positioning blocks 13, thereby adaptively positioning the workpiece. After the operation is completed, the pressing frame 8 will reset and drive the positioning block 13 to leave. The positioning block 13 will drive the round rod 14 to leave. The departure of the round rod 14 will drive the positioning wheel 15 to leave. The round rod 14 will reset through the elasticity between it and the positioning block 13. The round rod 14 will drive the positioning wheel 15 to reset elastically. Through flexible pre-alignment, the workpiece placement deviation and slight deformation are automatically corrected, and the processing datum is accurately determined. The elastic buffer positioning method avoids workpiece deformation and scratches caused by rigid pressure, while making the subsequent clamping force more uniform, effectively preventing workpiece movement and vibration during the cutting process, greatly improving cutting accuracy and finished product qualification rate, and shortening changeover and debugging time.

[0044] Example 2:

[0045] Please see Figures 5-6 Based on the above embodiments, in another embodiment of the present invention, the general-purpose laser cutting equipment for steel profiles and steel pipes further includes an anti-collision mechanism 16 installed on the laser device 4 for protecting the laser end of the laser device 4.

[0046] The anti-collision mechanism 16 includes a guide block 161 mounted on the adjustment bracket 3, a limiting rod 164 mounted on the laser device 4, an L-shaped rod 162 mounted on the limiting rod 164, an inclined block 163 mounted on the L-shaped rod 162, and a protective shell 165 mounted on the side of the L-shaped rod 162 away from the inclined block 163.

[0047] The L-shaped rod 162 contacts the outer wall of the laser device 4. A spring is provided between the L-shaped rod 162 and the laser device 4. An inclined surface is provided on the inclined block 163 and the guide block 161. The inclined block 163 contacts the outer wall of the guide block 161.

[0048] The general-purpose laser cutting equipment for steel profiles and pipes also includes a lifting mechanism installed on the multi-row adaptive clamping frame 6, which is used to lift the round pipe after processing;

[0049] The lifting mechanism includes a rotating rod 168 mounted on a multi-row adaptive clamping frame 6, a lifting plate 169 mounted on the rotating rod 168, a fixing block 166 mounted on a lower pressure frame 8, and a pull rod 167 mounted on the fixing block 166. The rotating rod 168 and the pull rod 167 are hinged together.

[0050] In this embodiment, during operation: When the laser device 4 is working, it will initiate a downward movement. This movement will cause the limiting rod 164 to move, which in turn causes the L-shaped rod 162 to shift. This shift in the L-shaped rod 162 will then cause the protective shell 165 to move. Simultaneously, the L-shaped rod 162 will cause the inclined block 163 to move away from the guide surface of the guide block 161. At this time, the L-shaped rod 162 will extend due to its elasticity with the laser device 4, and will simultaneously cause the protective shell 165 to open. After the protective shell 165 moves away, the laser emission end of the laser device 4 opens, thus initiating the laser device 4 to weld the workpiece. After welding, the laser device 4 will rise and reset. The movement of the laser device 4 will cause the limiting rod 164 to reset, and the limiting rod 164 will cause the L-shaped rod 162 to rise. The L-shaped rod 162 will then cause the inclined block 163 to move along the guide block 161. As the inclined block 163 rises, it will contact the inclined surface of the guide block 161, thereby squeezing the inclined surface of the inclined block 163. The squeezing of the inclined block 163 will cause it to move, and the movement of the inclined block 163 will drive the L-shaped rod 162 to retract. The retraction of the L-shaped rod 162 will compress the spring between the L-shaped rod and the laser device 4. At the same time, the L-shaped rod 162 will drive the protective shell 165 to approach the laser emitting end of the laser device 4. Thus, the two protective shells 165 approach the laser emitting end of the laser device 4 to protect it. This can effectively block the high-temperature molten slag, splashing smoke and dust generated during cutting from adhering to or hitting the laser head lens and nozzle, avoiding the burning and clogging of optical components, extending the service life, ensuring stable laser output and consistent cutting quality, reducing equipment failure rate and maintenance costs, and preventing accidental collision damage to the laser head, thus improving the safety and reliability of continuous operation of the equipment.

[0051] After clamping ends, the lower pressure frame 8 opens, causing the fixed block 166 to shift. This shift in the fixed block 166, through the hinge point, pulls the pull rod 167 upward. The pull rod 167 is hinged to the center point of the rotating rod 168, causing the pull rod 167 to rotate and move upward. This upward movement of the rotating rod 168 then causes the lifting plate 169 to rotate and move upward, thus lifting the processed round tube. When the lower pressure frame 8 closes, its downward movement causes the fixed block 166 to reset. The fixed block 166, through the pull rod 167, drives the rotating rod 168 to rotate and reset, which in turn drives the lifting plate 169 to reset. This facilitates continuous lifting of the processed workpiece, preventing the long round tube from sagging and deforming, ensuring the stability of the cutting axis, improving cutting accuracy, and preventing the tube end from shaking or swinging, reducing vibration, improving cutting quality and safety, ensuring smooth material feeding, preventing workpiece jamming, bumps, and scratches, and improving yield and output efficiency.

[0052] Example 3:

[0053] Please see Figures 7-8 Based on the above embodiments, in another embodiment of the present invention, the impurity cleaning mechanism 17 of the general-purpose laser cutting equipment for steel profiles and steel pipes is installed on the multi-row adaptive clamping frame 6 for cleaning impurities in the gaps of the machine tool.

[0054] The impurity cleaning mechanism 17 includes a base plate 171 mounted on a multi-row adaptive clamping frame 6, a rotating rod 172 mounted inside the base plate 171, a flipping plate 173 mounted on the rotating rod 172, a gear 174 mounted on the rotating rod 172, and a rack 175 mounted on the cutting machine tool 1.

[0055] Gear 174 meshes with rack 175, flipping plate 173 contacts the outer wall of cutting machine tool 1, and base plate 171 contacts the outer wall of gear 174.

[0056] The air-cooling mechanism of the general-purpose laser cutting equipment for steel sections and pipes is installed on the adjusting bracket 3 and is used to air-cool the welded parts when cutting the welded parts;

[0057] The air-cooling mechanism includes an air valve 176 installed on the adjusting bracket 3, a delivery pipe 177 installed at the output end of the air valve 176, and an exhaust head 178 installed on the adjusting bracket 3. The side of the delivery pipe 177 away from the air valve 176 is fixedly installed with the exhaust head 178.

[0058] In this embodiment, after the laser device 4 completes the welding of the workpiece, the multi-row adaptive clamping frame 6 resets and discharges the material, which simultaneously drives the base plate 171 to reset. The base plate 171 moves along the movement trajectory of the multi-row adaptive clamping frame 6, and the base plate 171 simultaneously drives the rotating rod 172 to move. The movement of the rotating rod 172 drives the flipping plate 173 to move. At the same time, the rotating rod 172 drives the gear 174 to move. The movement of the gear 174 moves along the teeth of the rack 175. The gear 174 meshes with the rack 175, so the gear 174 rotates while moving. The rotation of the gear 174 drives the rotating rod 172 to rotate. The rotation of the rotating rod 172 drives the flipping plate 173 to rotate. The rotation of the flipping plate 173 cleans and unblocks the internal gaps and impurities of the cutting machine tool 1, which can prevent the accumulation and blockage of molten slag and iron filings, ensure the smooth discharge of smoke and waste, and prevent the table from overheating and deforming. It can also reduce debris from jamming moving parts of the equipment, reduce the failure rate, keep the cutting environment clean, ensure stable subsequent processing, and extend the service life of the equipment.

[0059] While the laser device 4 is performing laser cutting, the downward movement of the laser device 4 will align the laser end with the workpiece. At this time, the sensor on the adjusting bracket 3 will adjust the light source to the laser device 4. The downward movement of the laser device 4 will activate the air valve 176. The operation of the air valve 176 will allow compressed air to enter the body, and then the compressed cold air will be delivered to the interior of the exhaust head 178 through the delivery pipe 177. The exhaust head 178 will open the cooling port and aim it at the workpiece being welded for air cooling. The exhaust head 178 will quickly reduce the temperature of the welding area, reduce the thermal deformation of the workpiece, ensure dimensional accuracy, suppress grain coarsening, improve the microstructure of the weld and heat-affected zone, and enhance the welding strength and toughness. At the same time, it will prevent the workpiece from overheating and burning, oxidizing and discoloring, improve the appearance quality of the weld, reduce welding stress, reduce the risk of cracking, and improve the stability of the joint.
