Description

Technical Field

[0001] This invention relates to the field of laser cutting machine technology, and in particular to a laser cutting device and method for stainless steel honeycomb core panels. Background Technology

[0002] Stainless steel honeycomb panels are products made by laminating brushed or mirror-finish stainless steel sheets for the surface, galvanized steel sheets for the back, and aluminum honeycomb core with a special adhesive. Laser cutting machines are typically used to process the stainless steel honeycomb core substrate. During the cutting process, the laser beam is focused into a very small focal point by the lens of the cutting head, achieving high power density at the focal point. The material is quickly heated to its melting and vaporization temperature. Simultaneously, a high-speed airflow blows the molten and vaporized material out from the coaxial or non-coaxial side, creating holes in the material. With the relative movement of the focal point and the material, continuous, narrow kerfs are formed, completing the cutting process.

[0003] Existing laser cutting machine operating tables use multiple rows of support teeth plates to support the workpiece to be cut. The support teeth plates usually have a serrated design. This design can reduce the contact area between the material and the support plate, thereby reducing laser reflection and heat accumulation. However, the iron slag and debris accumulated on the support teeth plates can cause the workpiece to be placed unevenly, resulting in vibration during cutting. In addition, the surface of the serrated support structure is relatively difficult to clean. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a laser cutting device and method for stainless steel honeycomb core panels. By incorporating a scraper, the surface and ends of the support columns can be cleaned, thereby resolving the problems in the prior art.

[0005] To achieve the above-mentioned technical objectives, the specific technical solution of the present invention is as follows: The present invention proposes a laser cutting device for stainless steel honeycomb core panels, comprising: a frame, an X-axis moving mechanism, a Y-axis moving mechanism, a support device, a laser cutting box, and a laser cutting head mounted on the laser cutting box; the laser cutting box is connected to the Y-axis moving mechanism, and the Y-axis moving mechanism has moving seats connected to both ends, which are connected to the X-axis moving mechanism; the support device includes a support frame, which is fixedly connected to the frame, and multiple sets of support components are connected inside the support frame for supporting the stainless steel honeycomb core panels; the support components include a semi-circular waste tube, with a pair of connecting seats fixedly connected to both ends of the waste tube, the connecting seats being fixedly connected to the support frame, and a scraper plate rotatably connected to the connecting seats and eccentrically disposed on the waste tube, with multiple support columns movably connected to the scraper plate; a drive mechanism for rotating the scraper plate is installed on the support frame.

[0006] As a preferred embodiment of the present invention, a support frame is provided inside the waste pipe. The support frame is fixedly connected to the support column, and multiple support wheels are installed on the support frame. The support wheels are in contact with the inner wall of the waste pipe, and an elastic element is fixedly connected between the support frame and the scraper.

[0007] As a preferred embodiment of the present invention, the driving mechanism includes a movable frame, a track that is slidably connected to the movable frame and fixedly connected to the support frame, a rotating shaft that is fixedly connected to the scraper plate, a fixed rod that is fixedly connected to the rotating shaft, and a connecting rod that is hinged between the fixed rod and the movable frame.

[0008] As a preferred embodiment of the present invention, the driving mechanism further includes a lead screw frame, a transmission lead screw, and a servo motor. A threaded block that is slidably connected to the lead screw frame is fixedly connected to the moving frame, and the threaded block is threadedly connected to the transmission lead screw.

[0009] As a preferred embodiment of the present invention, a semi-circular sealing tube is rotatably connected to the periphery of the waste pipe, and the sealing tube is rotatably connected to the connecting seat. When the scraper plate rotates, it drives the sealing tube to rotate.

[0010] As a preferred embodiment of the present invention, one end of the waste pipe is provided with a discharge port, and the other end of the waste pipe is connected to an air pipe for blowing the waste in the waste pipe toward the discharge port. An air inlet pipe is installed at one end of the support frame and is connected to each air pipe.

[0011] As a preferred embodiment of the present invention, a first bracket is fixedly connected to the sealing tube, a second bracket is fixedly connected to the scraper plate, a slider is fixedly connected to the second bracket, and the slider is slidably connected to the first bracket; and the waste tube is provided with an avoidance groove that cooperates with the first bracket.

[0012] As a preferred embodiment of the present invention, the inner wall of the waste pipe is provided with a cleaning section for cleaning the end of the support column.

[0013] A method of using a laser cutting device for stainless steel honeycomb core panels includes:

[0014] Laser cutting: The stainless steel honeycomb core panel is placed on the support device, and the movement trajectory of the laser cutting head is controlled by the X-axis moving mechanism and the Y-axis moving mechanism to cut the stainless steel honeycomb core panel;

[0015] Support column cleaning: The scraper is driven to rotate by the drive mechanism. When the scraper rotates, it causes the support column to retract. During the retraction process, the scraper cleans the waste residue on the surface of the support column. At the same time, the end of the support column rubs against the inner wall of the cleaning part while the scraper rotates, cleaning the waste residue at the end of the support column.

[0016] Waste pipe cleaning: The scraper is rotated 180° by the drive mechanism, and the sealing pipe is rotated to the top of the waste pipe to seal the waste pipe. Then, air is introduced into the air inlet pipe by the blower. The high-speed airflow passes through each waste pipe and blows the waste residue in the waste pipe to the outlet for discharge.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This invention features a waste pipe and a scraper. Multiple support columns are connected to the scraper. When the scraper rotates, it causes the support columns to retract, cleaning the waste residue on the surface of the support columns and dropping it into the waste pipe. This achieves the purpose of quickly cleaning the surface of the support columns and prevents the waste residue on the support columns from affecting the level and stability of the stainless steel honeycomb core panel.

[0019] 2. This invention connects a sealing pipe to the outside of the waste pipe. When the scraper rotates, it drives the sealing pipe to rotate, thus sealing the waste pipe. Then, by conveying high-pressure airflow into the waste pipe, the waste residue inside the waste pipe is cleaned out, thereby quickly cleaning the waste pipe. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Example 1: This example discloses a laser cutting device for stainless steel honeycomb core panels, such as... Figures 1-8 As shown, it includes: a frame 1, an X-axis moving mechanism 3, a Y-axis moving mechanism 4, a support device 2, a laser cutting box 5, and a laser cutting head 51 mounted on the laser cutting box 5. The laser cutting head 51 can be raised and lowered. The laser cutting box 5 is connected to the Y-axis moving mechanism 4, which can drive the laser cutting box 5 to move. The Y-axis moving mechanism 4 has moving seats 6 connected to both ends, and the moving seats 6 are connected to the X-axis moving mechanism 3. The movement trajectory of the laser cutting head 51 can be controlled through the X-axis moving mechanism 3 and the Y-axis moving mechanism 4 to cut the stainless steel honeycomb core panel.

[0031] like Figures 2-6As shown, the support device 2 includes a support frame 21, which is fixedly connected to the frame 1. Multiple sets of support components 22 are connected within the support frame 21 for supporting the stainless steel honeycomb core panel. Each support component 22 includes a semi-circular waste pipe 222 with its opening facing upwards. A pair of connecting seats 225 are fixedly connected to both ends of the waste pipe 222. The connecting seats 225 are fixedly connected to the support frame 21. A scraper plate 223 is rotatably connected to the connecting seat 225, eccentrically positioned relative to the waste pipe 222. That is, the rotation center of the scraper plate 223 is not directly opposite to the center of the waste pipe 222. At the same point, multiple support columns 224 are movably connected to the scraper 223, supporting the stainless steel honeycomb core panel; a support frame 226 is also provided inside the waste pipe 222, which is fixedly connected to the support columns 224, and multiple support wheels 227 are installed on the support frame 226. The support wheels 227 contact the inner wall of the waste pipe 222, and an elastic element 2210 is fixedly connected between the support frame 226 and the scraper 223. The elastic element 2210 applies elastic force to the support frame 226, causing the support wheels 227 to contact the inner wall of the waste pipe 222; during cleaning, if Figure 4 As shown, by rotating the scraper 223 counterclockwise, the support column 224 retracts towards the scraper 223 under the elastic force of the elastic element 2210 during the rotation of the scraper 223. During the retraction, the scraper 223 scrapes off the waste residue on the surface of the support column 224. During the rotation of the scraper 223, the waste tube 222 rubs against the end of the support column 224, cleaning off the waste residue at the end of the support column 224. The cleaned waste residue falls into the waste tube 222, thereby achieving the purpose of quickly cleaning the support assembly 22. Compared with the sawtooth support structure in the existing laser cutting machine, this embodiment, by adopting the waste tube 222, scraper 223 and support column 224, can quickly clean the waste residue on the support column 224, solving the problem of inconvenient cleaning of the sawtooth support structure in the existing laser cutting machine.

[0032] Preferably, the inner wall of the waste pipe 222 is provided with a cleaning part 2215 for cleaning the end of the support column 224. During the rotation of the scraper 223, the surface of the cleaning part 2215 contacts the end of the support column 224 to clean away the waste residue at the end of the support column 224.

[0033] like Figure 8As shown, a drive mechanism 23 for rotating the scraper 223 is installed on the support frame 21. The drive mechanism 23 includes a movable frame 234. A track 237 is fixedly connected to the support frame 21 and slidably connected to the movable frame 234. The track 237 supports both ends of the movable frame 234. A rotating shaft 2216 is fixedly connected to the scraper 223. A fixed rod 2217 is fixedly connected to the rotating shaft 2216. A connecting rod 235 is hinged between the fixed rod 2217 and the movable frame 234. The drive mechanism 23 also includes a lead screw frame 231, a transmission lead screw 232, and a servo motor 233. The lead screw frame 231 is fixedly connected to the support frame 21. A threaded block 236 is fixedly connected to the movable frame 234 and slidably connected to the lead screw frame 231. The threaded block 236 is threadedly connected to the transmission lead screw 232. The servo motor 233 drives the transmission lead screw 232 to rotate, which drives the movable frame 234 to move horizontally, thereby driving the scraper 223 to rotate.

[0034] Example 2: Based on the structure of Example 1 above, to facilitate the cleaning of waste residue inside the waste pipe 222, as follows: Figure 4 As shown, in this embodiment, a semi-circular sealing pipe 221 is rotatably connected to the periphery of the waste pipe 222. The sealing pipe 221 is rotatably connected to the connecting seat 225. The opening of the sealing pipe 221 faces upward, and the sealing pipe 221 can seal the waste pipe 222 when rotated 180°. When the scraper plate 223 rotates, it drives the sealing pipe 221 to rotate. One end of the waste pipe 222 is provided with a discharge port 229, and the other end of the waste pipe 222 is connected to an air pipe 228, which is used to blow the waste in the waste pipe 222 toward the discharge port 229. The waste residue is finally discharged from the discharge port 229. One end of the support frame 21 is equipped with an air inlet pipe 24, which is connected to each air pipe 228. The air inlet pipe 24 is connected to an external fan, and the fan delivers high-pressure airflow into the air inlet pipe 24.

[0035] like Figure 7 As shown, a first bracket 2211 is fixedly connected to the sealing tube 221, a second bracket 2212 is fixedly connected to the scraper 223, and a slider 2213 is fixedly connected to the second bracket 2212. The slider 2213 is slidably connected to the first bracket 2211. When the scraper 223 rotates, it drives the sealing tube 221 to rotate, and at the same time, the slider 2213 slides on the first bracket 2211. The waste tube 222 is provided with an avoidance groove 2214 that cooperates with the first bracket 2211, so that the sealing tube 221 can seal the waste tube 222.

[0036] In practice: when it is necessary to clean the waste pipe 222, the drive mechanism 23 drives the scraper 223 to rotate counterclockwise, the scraper 223 drives the sealing pipe 221 to rotate counterclockwise 180°, the sealing pipe 221 seals the waste pipe 222, and then the blower delivers high-pressure airflow into each waste pipe 222 to blow the waste residue to the discharge port 229 and discharge it from the discharge port 229, thereby quickly cleaning the waste residue in the waste pipe 222.

[0037] This embodiment also discloses a method of using a laser cutting device for stainless steel honeycomb core panels, which, based on the above-mentioned cutting device, includes:

[0038] Laser cutting: The stainless steel honeycomb core panel is placed on the support device 2, and the movement trajectory of the laser cutting head 51 is controlled by the X-axis moving mechanism 3 and the Y-axis moving mechanism 4 to cut the stainless steel honeycomb core panel.

[0039] Cleaning of support column 224: The scraper 223 is driven to rotate by the drive mechanism 23. When the scraper 223 rotates, it causes the support column 224 to retract. During the retraction process, the scraper 223 cleans the waste residue on the surface of the support column 224. At the same time as the scraper 223 rotates, the end of the support column 224 rubs against the inner wall of the cleaning part 2215 to clean the waste residue at the end of the support column 224.

[0040] Waste pipe 222 cleaning: The scraper 223 is rotated 180° by the drive mechanism 23, and the sealing pipe 221 rotates to the top of the waste pipe 222 to seal the waste pipe 222. Then, air is introduced into the air inlet pipe 24 by the blower. The high-speed airflow passes through each waste pipe 222 and blows the waste residue in the waste pipe 222 to the discharge port 229 for discharge.
