Description

Technical Field

[0001] This invention relates to the field of cutting device technology, and more specifically, to a cutting device and method for producing thermal insulation aluminum composite materials. Background Technology

[0002] Thermally insulated aluminum composite materials have wide applications in construction, transportation, aerospace, and other fields. Precise cutting is typically required during the production of these materials. Currently, laser cutting, as a highly efficient and precise cutting method, is widely used in the processing of thermally insulated aluminum composite materials. During laser cutting, the laser irradiation on the material generates slag and fumes, which need to be removed promptly to avoid affecting cutting quality and equipment operation.

[0003] Existing laser cutting equipment typically uses a sword grid to support the workpiece for chip removal. During use, the sword grid is inevitably subjected to ablation by the laser beam and the adhesion of molten slag. Especially when laser cutting insulated aluminum plates, the cutting area is often concentrated in the center of the sword grid, causing the damage rate in the center to be much higher than on the sides. When the center of the sword grid is severely worn, even if the sides are still intact, it is often necessary to replace the entire sword grid in the cutting area, increasing production costs and wasting undamaged sword grid material. This replacement method is not only time-consuming and labor-intensive, requiring downtime for manual disassembly and installation, reducing production efficiency, but also fails to fully utilize the overall lifespan of the sword grid, leading to material waste and increased costs. Summary of the Invention

[0004] This invention provides a cutting device and method for producing thermal insulation aluminum composite materials, which solves the technical problem in related technologies that when the middle of the blade grid is severely worn, even if the two sides of the blade grid are still intact, it is often necessary to replace the entire blade grid in the cutting area, which increases production costs and causes waste of undamaged blade grids.

[0005] The first aspect of this invention provides a cutting device for producing thermally insulated aluminum composite materials, characterized in that it comprises: A laser cutting machine, comprising a first base, on which a worktable is fixedly mounted, and a chip removal area extending from top to bottom is provided inside the worktable, and multiple sets of sword grid assemblies are arranged in parallel inside the chip removal area; Each set of the sword grid assembly includes two sets of individual sword grids with the same structure, and the two sets of individual sword grids are symmetrically distributed on both sides of the chip removal area; The switching unit is used to switch between two sets of individual sword grates. It includes a second base embedded inside a first base. A first support platform and a second support platform are arranged parallel to each other above the second base. The first support platform and the second support platform are detachably connected to their corresponding individual sword grates. A displacement support platform is slidably arranged at the bottom of the second support platform. A floating mechanism is arranged between the second base and the displacement support platform. The floating mechanism is used to drive the second support platform to float up and down, so that the second support platform drives the corresponding individual sword grates to pass through the bottom of the individual sword grates corresponding to the first support platform.

[0006] As a further optimization of the present invention, the floating mechanism includes sliding plates disposed on both sides below the displacement support platform, a track platform disposed below the sliding plates, a floating track being provided inside the track platform, a pulley being slidably connected inside the floating track, a connecting seat being rotatably connected to the pulley via a bearing, the connecting seat passing through the sliding plate and being fixedly connected to the displacement support platform, and a driving mechanism for driving the two sets of sliding plates to move synchronously is provided between the two sets of sliding plates.

[0007] As a further optimization of the present invention, the sliding plate has a slot inside that is adapted to the connecting seat.

[0008] As a further optimization of the present invention, the floating track includes a first horizontal groove, a second horizontal groove symmetrically arranged on both sides of the first horizontal groove, and an inclined groove connecting the first horizontal groove and the two sets of second horizontal grooves respectively. The horizontal height of the two sets of second horizontal grooves is higher than the horizontal height of the first horizontal groove. The pulley can slide along the first horizontal groove, the inclined groove and the second horizontal groove, thereby driving the displacement support platform to float up and down.

[0009] As a further optimization of the present invention, both sides of the second base are vertically fixed with upright plates, and both sets of upright plates are rotatably connected to a wheel disk through bearings. A synchronous belt is sleeved on both sets of wheel disks. The synchronous belt has a closed-loop structure and is divided into an upper parallel section and a lower parallel section. Both sides of the first support platform are fixedly connected to the upper parallel section of the synchronous belt, and the sides of the two sets of sliding plates that are far apart are fixedly connected to the lower parallel section of the synchronous belt. When the sliding plates move, the synchronous belt can drive the first support platform and the sliding plates to move synchronously in opposite directions.

[0010] As a further optimization of the present invention, the driving mechanism includes screws rotatably connected to both sides of the second base via bearings. Screw sleeves are threaded onto the screws, and the screw sleeves are fixedly connected to the sliding plate. The two sets of screws are connected by a belt pulley transmission mechanism. A motor is also installed on the second base, and the output shaft of the motor is fixedly connected to one of the sets of screws to drive the screws to rotate.

[0011] As a further optimization of the present invention, a displacement mechanism is provided between the second support platform and the displacement support platform. The displacement mechanism is used to drive the second support platform to move the corresponding single sword grid horizontally, so that the two sets of single sword grids are staggered and avoid obstruction and jamming during switching. The displacement mechanism includes a first through-hole opened in the displacement support platform. A first sliding block is slidably connected inside the first through-hole, and the first sliding block is fixedly connected to the second support platform. A cylinder is installed on the displacement support platform. The telescopic end of the cylinder is fixedly connected to the first sliding block and is used to drive the first sliding block to slide along the first through-hole.

[0012] As a further optimization of the present invention, an assembly unit is provided between the first support platform and the corresponding single sword grating, and between the second support platform and the corresponding single sword grating. The assembly unit is used to realize the rapid assembly and disassembly of the support platform and the single sword grating. The assembly unit includes a mounting seat installed on the first support platform and the second support platform respectively. The mounting seat has a mounting groove adapted to the single sword grating inside. Multiple sets of single sword gratings are respectively assembled in the corresponding mounting groove.

[0013] As a further optimization of the present invention, a slot is provided on one side of the mounting groove, and a locking block is movably disposed inside the slot. The side of the locking block away from the slot abuts against the side wall of the single sword grid.

[0014] A second aspect of the present invention provides a cutting method for producing thermal insulation aluminum composite materials, comprising the following steps: S1. Place the thermal insulation aluminum composite material workpiece to be cut on the worktable and support it with multiple sets of sword grid assemblies; S2. Start the laser cutting machine to laser cut the workpiece. The waste generated by the cutting falls into the chip removal area through the gap between the sword grid assembly. S3. When cutting is complete or it is necessary to switch the individual sword grid that carries the waste, perform the individual sword grid exchange operation, which specifically includes: S31. Start the drive mechanism to drive the sliding plate to move horizontally; S32. When the sliding plate moves, the first support platform moves synchronously in the opposite direction to the sliding plate via a synchronous belt; S33. At the same time, the sliding plate drives the displacement support platform and the second bearing platform set on it to float up and down through the cooperation of its internal pulley and the floating track fixed on the second base, so that the second bearing platform passes under the first bearing platform, thereby realizing the left and right exchange of the two sets of single sword grids. S4. After the exchange is completed, step S2 can be executed to cut the new workpiece.

[0015] The beneficial effects of this invention are as follows: 1. This invention enables the left-right switching of two sets of individual sword grates through an exchange unit. When the center of an individual sword grating is rapidly damaged due to laser cutting, the exchange unit swaps the entire set of individual sword grates on both sides. This moves the damaged individual sword grating from the center to the sides, while the intact individual sword gratings from the sides are moved to the center, allowing them to continue to be used. This greatly extends the overall service life of the sword grating, avoids the waste of replacing the entire set due to partial damage, and directly reduces consumable costs.

[0016] 2. By setting up an exchange unit and utilizing the synergistic effect of the floating mechanism and the drive mechanism, this invention can achieve rapid and automated switching between two sets of individual sword grids. When the effective cutting area of ​​one set of individual sword grids is worn, there is no need to stop the machine for manual replacement. Instead, the exchange unit can quickly switch another set of standby individual sword grids to the working position, thereby shortening downtime and improving equipment utilization and production efficiency.

[0019] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0020] Example 1: According to the appendix Figure 1 To be continued Figure 4 As shown, this invention provides a cutting device for the production of thermally insulated aluminum composite materials. This cutting device is mainly used for high-precision laser cutting of thermally insulated aluminum composite materials in industrial production, and for realizing rapid and automated left-right exchange of the waste material carrier grid during the cutting process. The cutting device includes a laser cutting machine 100 and an exchange unit 200.

[0021] The laser cutting machine 100 includes a first base 110, a worktable 120 mounted on the first base 110, a gantry frame 130 above the worktable 120, a sliding table 140 mounted on the gantry frame 130, and a laser cutter 150 mounted on the sliding table 140. The laser cutter 150 can be a high-power fiber laser or a CO2 laser, depending on the specific cutting requirements. The worktable 120 has a through-type chip removal area inside to collect and remove waste generated during the cutting process.

[0022] Multiple sets of sword guard assemblies 160 are arranged in parallel inside the chip removal zone. The sword guard assemblies 160 are used to support the workpiece to be cut and allow waste to fall into the chip removal zone. Each set of sword guard assemblies 160 includes two sets of individual sword guards with the same structure, and the two sets of individual sword guards are symmetrically distributed on both sides of the chip removal zone.

[0023] The movement control section of the laser cutting machine 100 includes a first base 110 and a gantry 130 connected by a Y-axis drive assembly, which drives the gantry 130 to move along the Y-axis direction, thereby controlling the positioning of the laser cutter 150 in the Y-axis direction; the gantry 130 and a sliding table 140 are connected by an X-axis drive assembly, which drives the sliding table 140 to move along the X-axis direction, thereby controlling the positioning of the laser cutter 150 in the X-axis direction; the sliding table 140 and the laser cutter 150 are connected by a Z-axis drive assembly, which drives the laser cutter 150 to move along the Z-axis direction, thereby controlling the focal position and cutting depth of the laser beam.

[0024] According to the appendix Figure 5 and attached Figure 6 As shown, the exchange unit 200 is used to realize the left-right exchange of two sets of individual sword grates. The exchange unit 200 includes a second base 210 embedded inside the first base 110. A first support platform 220 and a second support platform 230 are arranged parallel above the second base 210. The first support platform 220 and the second support platform 230 are respectively used to support the corresponding individual sword grates and are detachably connected to the individual sword grates through the assembly unit 300. A displacement support platform 260 is slidably arranged at the bottom of the second support platform 230.

[0025] The floating mechanism 240 is located between the second base 210 and the displacement support platform 260. Its core function is to drive the second support platform 230 to float up and down. Through floating, the second support platform 230 can drive the corresponding single sword grid to pass through the bottom of the corresponding single sword grid on the first support platform 220, thereby realizing unobstructed relative switching of the left and right single sword grids.

[0026] According to the appendix Figure 6 and attached Figure 7 As shown, the floating mechanism 240 includes sliding plates 241 disposed on both sides below the displacement support platform 260. A track platform 242 is correspondingly disposed below the sliding plates 241, and the track platform 242 is fixedly connected to the second base 210. A floating track 243 is formed inside the track platform 242, and a pulley 244 is slidably connected inside the floating track 243. A connecting seat 245 is rotatably connected to the pulley 244 via a bearing. The top end of the connecting seat 245 passes through the sliding plate 241 and is fixedly connected to the displacement support platform 260. A guide rail is mounted on the second base 210, and a guide rail sleeve is slidably connected to the guide rail, and the guide rail sleeve is fixedly connected to the sliding plate 241.

[0027] When the cutting device is running, a drive mechanism 250 is provided between the two sets of sliding plates 241 to drive the two sets of sliding plates 241 to move synchronously. The sliding plate 241 has a slot inside that is adapted to the connecting seat 245. The slot allows the connecting seat 245 to slide in the floating track 243 with the pulley 244, thereby driving the displacement support platform 260 to move up and down.

[0028] Preferably, according to the appendix Figure 7 and attached Figure 8 As shown, the floating track 243 includes a horizontally arranged first flat groove 2431, second flat grooves 2432 symmetrically arranged on both sides of the first flat groove 2431, and inclined grooves 2433 connecting the first flat groove 2431 and the two sets of second flat grooves 2432 respectively; the horizontal height of the two sets of second flat grooves 2432 is higher than the horizontal height of the first flat groove 2431. During the switching of the single sword grid, the pulley 244 can slide along the first flat groove 2431, the inclined groove 2433 and the second flat groove 2432.

[0029] When the pulley 244 is in the first flat groove 2431, the second support platform 230 is in a lower position; when the pulley 244 moves to the second flat groove 2432 through the inclined groove 2433, the second support platform 230 is driven to rise to a higher position, thereby causing the displacement support platform 260 to float up and down to cooperate with the switching action of the single sword grid.

[0030] More preferably, in order to guide and limit the floating of the displacement support platform 260, guide sleeves 246 are embedded and fixed around the inside of the sliding plate 241. Guide rods 247 are slidably inserted inside the guide sleeves 246 and are fixedly connected to the displacement support platform 260. The cooperation between the guide sleeves 246 and the guide rods 247 is like a linear guide rail, ensuring that the movement of the displacement support platform 260 in the vertical direction is smooth and precise, avoiding tilting or jamming.

[0031] Preferably, both sides of the second base 210 are vertically fixed with upright plates, and both sets of upright plates are rotatably connected with wheel disks 248 through bearings. Synchronous belts 249 are sleeved on the two sets of wheel disks 248. The synchronous belts 249 have a closed-loop structure and are divided into an upper parallel section and a lower parallel section. Both sides of the first support platform 220 are fixedly connected to the upper parallel section of the synchronous belt 249, and the sides of the two sets of sliding plates 241 that are far apart are fixedly connected to the lower parallel section of the synchronous belt 249.

[0032] When the sliding plate 241 moves under the action of the drive mechanism 250, the synchronous belt 249 will drive the first support platform 220 to move synchronously in the opposite direction to the sliding plate 241, ensuring the coordinated movement of the two sets of individual sword grids during the switching process and realizing the exchange of left and right positions.

[0033] According to the appendix Figure 6As shown, the drive mechanism 250 includes screws 251 rotatably connected to both sides of the second base 210 via bearings. Screw sleeves 252 are threaded onto the screws 251, and the screw sleeves 252 are fixedly connected to the sliding plate 241. The two sets of screws 251 are connected by a belt pulley transmission mechanism 253 to ensure that the two screws 251 rotate synchronously. A motor 254 is also installed on the second base 210. The output shaft of the motor 254 is fixedly connected to one of the sets of screws 251 to drive the screws 251 to rotate and precisely control the displacement of the sliding plate 241.

[0034] To further avoid obstruction and jamming during switching, especially when the two sets of individual sword grids pass through alternately, a displacement mechanism 270 is provided between the second support platform 230 and the displacement support platform 260. This mechanism drives the second support platform 230 to move the corresponding individual sword grid horizontally, so that the two sets of individual sword grids can be staggered, thereby avoiding hard collisions or jamming during switching.

[0035] According to the appendix Figure 9 As shown, the displacement mechanism 270 includes a first opening 271 on the displacement support platform 260. A first sliding block 272 is slidably connected inside the first opening 271, and the first sliding block 272 is fixedly connected to the second support platform 230. A cylinder 273 is installed on the displacement support platform 260. The telescopic end of the cylinder 273 is fixedly connected to the first sliding block 272, and is used to drive the first sliding block 272 to slide along the first opening 271, thereby driving the second support platform 230 to move horizontally.

[0036] More preferably, in order to enable the second support platform 230 to automatically reset or provide buffer when the cylinder 273 is not working, the displacement support platform 260 is symmetrically provided with second openings 274 on both sides. The second openings 274 are slidably connected with second sliding blocks 275. The second sliding blocks 275 are fixedly connected to the second support platform 230. The second sliding blocks 275 are slidably inserted with limit rods 276. Both ends of the limit rods 276 are fixedly installed with stops. The stops are fixedly connected to the displacement support platform 260 to form a structure that limits the movement range of the second sliding blocks 275. The two sides of the limit rods 276 are fitted with first springs 277. The two ends of the first springs 277 are fixedly connected to the stops and the second sliding blocks 275 respectively.

[0037] When the cylinder 273 drives the first sliding block 272 to move, the first spring 277 is compressed or stretched. When the cylinder 273 retracts, the first spring 277 can reset the second sliding block 275 to its initial position, ensuring accurate and reliable displacement and providing buffering.

[0038] To enable rapid assembly and disassembly of the support platform and the individual sword guard, in this embodiment, according to the appendix... Figure 10 and attached Figure 11As shown, an assembly unit 300 is provided between the first support platform 220 and the corresponding individual sword scabbard, and between the second support platform 230 and the corresponding individual sword scabbard. The assembly unit 300 includes a mounting base 310 respectively installed on the first support platform 220 and the second support platform 230. The mounting base 310 has a mounting groove 320 adapted to the individual sword scabbard inside. Multiple sets of individual sword scabbards are respectively assembled in the corresponding mounting groove 320.

[0039] More preferably, a slot 330 is provided on one side of the mounting groove 320, and a locking block 340 is movably disposed inside the slot 330. The side of the locking block 340 away from the slot 330 abuts against the side wall of the single sword grid to fix the single sword grid. A connecting plate 350 is installed on the locking block 340, and a connecting rod 360 is fixedly installed on both sides of the connecting plate 350. A sliding sleeve plate 370 is slidably sleeved on the outside of the connecting rod 360. The sliding sleeve plate 370 is installed on the mounting base 310. A second spring 380 is also sleeved on the outside of the connecting rod 360. The two ends of the second spring 380 are fixedly connected to the connecting plate 350 and the sliding sleeve plate 370 respectively to provide a clamping force for the locking block 340, so that the locking block 340 can always be tightly abutted against the side wall of the single sword grid to prevent the single sword grid from loosening.

[0040] Preferably, both the contact side of the slot 330 and the locking block 340 are inclined structures. This inclined structure facilitates the quick insertion of the locking block 340 into the slot 330 during installation. The side of the locking block 340 closest to the individual sword-like grid has several transverse slots. These slots increase the friction between the locking block 340 and the individual sword-like grid, further enhancing the fixing effect. The locking block 340 is made of rubber, which provides good friction while preventing scratches or damage to the surface of the individual sword-like grid when in contact with it.

[0041] Example 2: According to the appendix Figure 1 To be continued Figure 12 As shown, a cutting method for producing thermal insulation aluminum composite materials, using the above-mentioned cutting device for producing thermal insulation aluminum composite materials, includes the following steps: S1. Place the thermal insulation aluminum composite material workpiece to be cut on the worktable 120 and support it by multiple sets of sword grid assemblies 160. S2. Start the laser cutting machine 100 and control the laser cutter 150 to move through the X-axis drive assembly, Y-axis drive assembly and Z-axis drive assembly to perform laser cutting on the workpiece. The waste generated by cutting falls into the chip removal area through the gap between the sword grid assembly 160. S3. When cutting is complete or it is necessary to switch the individual sword grid that carries the waste, perform the individual sword grid exchange operation, which specifically includes: S31. Start the drive mechanism 250 to drive the sliding plate 241 to move horizontally; S32. When the sliding plate 241 moves, the first bearing platform 220 and the sliding plate 241 move synchronously in opposite directions through the synchronous belt 249. S33. At the same time, the sliding plate 241 drives the displacement support platform 260 and the second bearing platform 230 set on it to float up and down through the cooperation of its internal pulley 244 and the floating track 243 fixed on the second base 210, so that the second bearing platform 230 passes under the first bearing platform 220, thereby realizing the left and right exchange of the two sets of single sword grids. S4. After the exchange is completed, step S2 can be executed to cut the new workpiece.

[0042] Working principle: The thermally insulated aluminum composite material workpiece to be cut is placed on the worktable 120, supported by multiple sets of blade grid assemblies 160. After the laser cutting machine 100 is started, the laser cutter 150 is precisely moved in three-dimensional space by the X-axis, Y-axis, and Z-axis drive components, so that the laser beam is focused on the surface of the workpiece for cutting. The waste generated during the cutting process falls into the chip removal area inside the worktable 120 through the gaps between the blade grid assemblies 160, realizing the automatic collection and discharge of waste.

[0043] When cutting is completed or when waste accumulated on the individual sword grid affects subsequent operations, the device initiates an automated individual sword grid exchange process: The motor 254 of the drive mechanism 250 is started, which drives two screws 251 that rotate synchronously through the belt pulley transmission mechanism 253. The rotation of the screws 251 drives the screw sleeve 252 to move horizontally, thereby causing the two sets of sliding plates 241 fixed to the screw sleeve 252 to move synchronously along the guide rail on the second base 210.

[0044] When the sliding plate 241 moves, it drives the synchronous belt 249 to run through the lower parallel section of the synchronous belt 249 fixed to its side. Since the upper parallel section of the synchronous belt 249 is fixedly connected to the first support platform 220 and the lower parallel section is fixedly connected to the sliding plate 241, the first support platform 220 and the sliding plate 241 move synchronously horizontally in opposite directions and at the same speed, so that the two sets of support platforms and the individual sword grids on them move towards each other or away from each other.

[0045] As the sliding plate 241 moves horizontally, the connecting seat 245, fixed below the displacement support platform 260, slides along the floating track 243 within the track platform 242 via pulley 244. The floating track 243 consists of a horizontal first flat groove 2431, an inclined groove 2433, and a higher second flat groove 2432. When the pulley 244 slides from the first flat groove 2431 through the inclined groove 2433 into the second flat groove 2432, the connecting seat 245 drives the displacement support platform 260 and the second support platform 230 to rise as a whole; conversely, it lowers. This floating process allows the second support platform 230 to smoothly pass under the first support platform 220, enabling the left and right positions of the two sets of individual sword grids to be exchanged. Figure 12 As shown, the damaged area A in the middle is switched to both sides, and the intact areas B on both sides are switched to the middle.

[0046] To prevent hard collisions between individual sword grids during the exchange process, the cylinder 273 of the displacement mechanism 270 drives the first sliding block 272 to move horizontally, thereby fine-tuning the horizontal position of the second support platform 230 and the individual sword grids on it, so that the two sets of individual sword grids are staggered. The first spring 277 provides cushioning when the cylinder 273 resets and assists the second sliding block 275 in returning to its original position, ensuring accurate positioning. At the same time, the guiding system formed by the guide sleeve 246 and the guide rod 247 ensures that the displacement support platform 260 is stable and tilt-free during vertical floating.

[0047] When installing a single sword guard, insert the single sword guard into the mounting slot 320 of the mounting base 310. Under the elastic force of the second spring 380, the locking block 340 of the assembly unit 300 automatically locks into the slot 330 and tightly abuts against the side wall of the sword guard, achieving quick fixation. When disassembling, the single sword guard can be pulled out by overcoming the spring force and removing the locking block 340.

[0048] After the individual sword grids are exchanged, the device can immediately continue with a new round of cutting operations. Through the above-mentioned automated cycle of cutting and exchange, efficient and interference-free switching of waste-carrying individual sword grids is achieved in continuous production, significantly improving production efficiency and equipment utilization.

[0049] The embodiments of this specific implementation have been described above. However, this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.
