Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and more specifically, to a laser cutting device for processing aluminum alloy profiles. Background Technology

[0002] Aluminum alloy profiles refer to aluminum alloy extruded profiles in a specified shape. Due to their excellent properties such as light weight, high strength, and corrosion resistance, aluminum alloys are widely used in aerospace, automobile manufacturing, building decoration and many other fields.

[0003] Chinese patent application CN119260217A discloses a CNC laser cutting device for processing aluminum alloy profiles. The device includes a processing table with several sets of support columns fixedly connected to it, and a top plate fixedly connected to the top of each set of support columns. A processing assembly is fixedly connected to the output end of a telescopic cylinder. The processing assembly includes a top block with a first motor mounted at its bottom. A cutting mechanism is connected to the output end of the first motor. The device can rotate a first electric slide to a preset angle via the first motor, and the first electric slide can move a laser cutting blade horizontally to perform a linear cut on the aluminum alloy profile at a preset angle. Alternatively, the first electric slide can move the laser cutting blade horizontally to a preset position, and the first electric slide can rotate via the first motor to perform a circular cut on the aluminum alloy profile with a preset inner diameter.

[0004] Although the above patent uses the first electric slide to drive the laser cutting blade to move horizontally to perform straight cutting at a preset angle and circular cutting with a preset inner diameter on the profile, considering that aluminum alloy is used in many scenarios and the shape of the profile is diverse, when it is necessary to cut aluminum alloy profiles with curved angles, the shape cut by the flat cutting is much larger than the expected shape of the curved cutting, that is, it is necessary to adapt to the shape of the curved aluminum alloy profile for cutting.

[0005] In view of this, we propose a laser cutting device for processing aluminum alloy profiles. Summary of the Invention

[0034] Example 1

[0035] Please see Figures 1-8As shown, this embodiment provides a laser cutting device for processing aluminum alloy profiles, including a guard plate 1 and a guide base 2. Electric slide rails 11 are fixedly connected to both sides of the guard plate 1. A sliding frame 111 is slidably connected to the outer side of the electric slide rails 11. A sliding block 112 is slidably connected to the top outer wall of the sliding frame 111. A cutting head 113 is telescopically connected to the bottom of the sliding block 112. The guide base 2 is fixedly connected to the inner wall of the guard plate 1. A rotating frame 3 is slidably connected to the top of the guide base 2. A grid plate 31 is fixedly connected to the top of the rotating frame 3. A rack 32 is fixedly connected to the bottom of the outer wall of the rotating frame 3. A motor 21 is fixedly connected to the top of the guide base 2. A rotating rod 23 is rotatably connected to the top of the guide base 2. Side plates 24 are fixedly connected to both outer walls of the guide base 2. A limiting slider 25 is slidably connected to the top of the side plate 24. A limiting component 27 is provided on the inner side of the limiting slider 25.

[0036] like Figures 2-5 As shown, a first limiting post 114 is fixedly connected to both sides of the upper bottom of the sliding frame 111. A telescopic post 26 is fixedly connected to the outer wall of the limiting slider 25. The telescopic post 26 and the first limiting post 114 are on the same vertical plane. A transmission roller 211 is fixedly connected to the output end of the motor 21. A transmission belt 22 is sleeved on the outer wall of the transmission roller 211. The other end of the transmission belt 22 is sleeved on the outer wall of the rotating rod 23. A threaded protrusion 231 is fixedly connected to the outer wall of the rotating rod 23. The threaded protrusion 231 is meshed with the rack 32.

[0037] Among them, such as Figure 4 As shown, the upper end of the telescopic column 26 is bent at a 90-degree angle. When the aluminum alloy profile is transported to the telescopic column 26, the side of the bent part of the telescopic column 26 in the extended state will block the input end of the arc-shaped profile to a certain extent. The telescopic column 26 here is electrically telescopic.

[0038] like Figures 2-7As shown, a crossbar 241 is fixedly connected to the top of the side plate 24. An irregular groove 242 is formed on the top of the side plate 24, and a touch sensor is installed on the top of the irregular groove 242. A groove 2411 is formed at the bottom of the middle end of the crossbar 241. A limiting slider 25 is slidably connected between the top of the side plate 24 and the bottom of the crossbar 241. The limiting slider 25 is internally hollow. The limiting assembly 27 includes a first sliding member 271, which is U-shaped and slidably connected to the inner side of the limiting slider 25. A sliding post 2713 is fixedly connected to the top end of the first sliding member 271. The sliding post 2713 is slidably connected to the inner side of the limiting slider 25. A square groove 2711 is opened on the inner side of both sides of the first sliding member 271. A spring 2714 is provided on the top of the first sliding member 271. An extension plate 2712 is fixedly connected to the outer walls of both sides of the first sliding member 271. A second spring 272 is provided on the top of the extension plate 2712. The two ends of the second spring 272 abut against the top inner wall of the limiting slider 25 and the top of the extension plate 2712, respectively.

[0039] like Figures 2-8 As shown, a second sliding member 273 is slidably connected to the inner side of the limiting slider 25. A first spring 2714 is disposed between the first sliding member 271 and the second sliding member 273. Second square grooves 2731 are formed on both outer walls of the second sliding member 273, with the same height as the first square groove 2711. A latching strip 275 is fixedly connected to the top of the second sliding member 273, the width of which matches the width of the groove 2411. The shape of the irregular groove 242 is similar to that of the first... The bottom shape of the first slider 271 is matched. A connecting rod 274 is provided between the first slider 271 and the second slider 273. The middle end of the connecting rod 274 is rotatably connected to the inner wall of the limiting slider 25. The two ends of the connecting rod 274 are fixedly connected to the second limiting post 2741. The diameter of the second limiting post 2741 is the same as the height of the first square groove 2711 and the second square groove 2731. The two ends of the second limiting post 2741 are located inside the first square groove 2711 and the second square groove 2731, respectively.

[0040] Therefore, when cutting aluminum alloy profiles that require curved shapes, such as Figures 1-4As shown, the worker places the curved aluminum alloy profile on the top of the grid plate 31 and conveys it to the right. At this time, the telescopic column 26 in the extended state blocks the input end of the aluminum alloy profile. The aluminum alloy profile in the conveying state will drive the telescopic column 26 to slide to the right and slowly retract during the sliding process. As the height of the bent part of the telescopic column 26 decreases, it will gradually lose its obstruction of the aluminum alloy profile, allowing the aluminum alloy profile to be placed completely on the top of the grid plate 31. At this time, one side of the profile is a combination of curved surface and right angle surface. After the curved surface of the profile is placed on the grid plate 31, the cutting head 113 is used to perform a conventional cutting operation under the fixation of the telescopic column 26 and the first limiting column 114.

[0041] When the curved surface of some curved aluminum alloy profiles faces the same direction as the concave surface of the grid plate 31, the telescopic columns 26 on both sides will extend on one side and retract on the other during the conveying process. At this time, the bent part of one side of the telescopic column 26 is located at the top of the profile, and the other side is located at the bottom of the profile, and will not obstruct the profile. At this time, after the aluminum alloy profile is conveyed to the designated position, the transmission roller 211 rotates under the drive of the motor 21, and the rotating rod 23 and the threaded protrusion 231 rotate together under the drive of the transmission belt 22. The rack 32, the rotating frame 3, and the grid plate 31 will also rotate together. At this time, the aluminum alloy profile will also rotate at a certain angle under the rotation of the grid plate 31. However, under the influence of gravity and friction, if the rotation angle is too large, the aluminum alloy profile will slip, thus affecting the cutting efficiency when rotating at a large angle. At this time, the telescopic columns 26 on both sides will extend and retract with the rotation direction of the rotating frame 3. At the same time, with the restriction of the first limiting column 114, the rotation angle of the aluminum alloy profile is kept the same as the rotation angle of the rotating frame 3 during the rotation process.

[0042] Furthermore, during the sliding of the telescopic column 26, the limiting slider 25 will slide along with it. When the limiting slider 25 slides to the same vertical plane as the sliding frame 111, i.e., the initial position of the sliding frame 111, simultaneously, the first sliding member 271 moves downward under the elastic force of the first spring 2714 and enters the irregular groove 242. At this time, the first sliding member 271 contacts the touch sensor, causing the telescopic column 26 to stop its telescopic movement and reach the designated position to limit the arc-shaped aluminum alloy profile. At the same time, during the downward sliding of the first sliding member 271, the first square groove 2711 will use the middle position of the connecting rod 274 to lift the second sliding member 273, causing the second sliding member 273 to slide upward, and finally causing the second sliding member 273 to drive the latch. The buckle 275 extends into the groove 2411, limiting the position of the slider 25 and the telescopic column 26, so that the telescopic column 26 and the sliding frame 111 are on the same vertical plane. At this time, the bending position of the telescopic columns 26 on both sides and the first limiting column 114 are also on the same vertical plane. At this time, the telescopic column 26 at the top of the aluminum alloy profile will limit the height of the profile on one side, while the telescopic column 26 at the bottom of the aluminum alloy profile on the other side will fix the arc-shaped aluminum alloy profile with the first limiting column 114 (the end of the telescopic column 26 is used as the bottom support, and the first limiting column 114 is used for top fixation). Then, the rotating frame 3 is controlled to rotate, and it cooperates with the telescopic column 26 to complete some larger angle rotations, which can adapt to more angles of arc-shaped aluminum alloy profiles.

[0043] It should be noted that the initial position of the sliding frame 111 is located at the middle of the electric slide rail 11, while the initial positions of the limiting slider 25 and the telescopic column 26 are at the leftmost end. After the telescopic column 26 stops moving after reaching the middle position, it will extend and retract again when the motor 21 drives the rotating frame 3 to rotate. When the rotating frame 3 rotates, one side of the rotating frame 3 will gradually lower, while the other side will gradually rise. At this time, the telescopic column 26 on the raised side will also gradually rise, and vice versa. It is only necessary to ensure that the height of the bent part of the telescopic column 26 is consistent with the height of both sides of the rotating frame 3 after rotation.
