Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and specifically relates to a laser cutting device for aluminum profiles. Background Art

[0002] Aluminum profiles are aluminum tubes with different cross-sectional shapes obtained by melting and extruding aluminum rods. The forming process mainly includes melting and casting, extrusion, cutting, CNC milling and cutting, surface pretreatment, and coloring. They are mainly used in industrial production and manufacturing, such as automated mechanical equipment, frameworks, etc.

[0003] However, when cutting an H-shaped aluminum tube into sections, due to the high reflectivity of the aluminum profile surface, especially polished aluminum materials, part of the laser beam will be reflected, resulting in energy loss and reduced cutting efficiency. This reflection phenomenon may also damage the optical components of the laser equipment. Therefore, it is necessary to spray an antireflection film or deposit a thin film in vacuum on the surface of the H-shaped aluminum tube to reduce the reflection of laser energy and improve the cutting efficiency. However, it is not convenient to rotate the H-shaped aluminum tube during spraying, and if it is not fixed firmly, it is easy to cause cutting errors. Moreover, due to the softness and thermal properties of aluminum, burrs and residues on the bottom surface of the cut are likely to be generated during the cutting process, and additional post-treatment may be required. For this reason, we propose a laser cutting device for aluminum profiles. Summary of the Invention

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] Please refer to Figure 1 - Figure 9 , a laser cutting device for aluminum profiles, including a base 1, an outer shell 2 is installed at the upper end of the base 1, a laser cutting head 3 is installed inside the outer shell 2, a transfer mechanism 4 for moving the cut H-shaped aluminum tubes in sections is arranged on one side of the laser cutting head 3, a flipping mechanism 5 for rotating the H-shaped aluminum tubes is arranged on the other side of the laser cutting head 3, the transfer mechanism 4 includes a first motor 41, the first motor 41 is installed inside the outer shell 2, the output end of the first motor 41 is fixedly connected to a rotating rod 42, the outer side of the rotating rod 42 is rotatably connected to a first fixing plate 43, the lower end of the first fixing plate 43 is fixedly connected to the base 1, the outer side of the rotating rod 42 is fixedly connected to a first belt pulley 44, the front end of the rotating rod 42 is fixedly connected to an adapter 45, and clamping assemblies 46 are arranged at both ends of the adapter 45.

[0020] In this embodiment, the clamping assembly 46 includes a connecting plate 461. One side of the connecting plate 461 is fixedly connected with a rotating block 462. The rotating block 462 is rotatably connected with a rotating joint 45. The other side of the connecting plate 461 is fixedly connected with an ear 463. Electric push rods 464 are arranged at both the front and rear ends of the ear 463. The output end of the electric push rod 464 is fixedly connected with a clamping plate 465.

[0021] Specifically, when the other end of the H-shaped aluminum tube extends between the two clamping plates 465 and contacts the support block 466 at its lower end, the two electric push rods 464 closer to the laser cutting head 3 will be activated to contract upon receiving an instruction. This causes the two clamping plates 465 to approach the H-shaped aluminum tube, and the clamping rods 467 are inserted into the holes formed on both sides of the H-shaped aluminum tube, enabling the fixation of the H-shaped aluminum tube.

[0022] In this embodiment, the two clamping plates 465 are symmetric with each other. The clamping plate 465 is slidably connected with the connecting plate 461. The lower end of the clamping plate 465 is fixedly connected with a support block 466. Two clamping rods 467 are fixedly connected to the front end of the clamping plate 465.

The upper end of the second grinding plate 48 is fixedly connected with the housing 2.

[0023] Specifically, during the process of the clamping assembly 46 flipping and transferring the cut H-shaped aluminum tube, the cross-sections at both ends of the H-shaped aluminum tube will respectively come into frictional contact with the first grinding plate 47 and the second grinding plate 48, thereby removing the burrs on the cross-section of the H-shaped aluminum tube section.

[0024] In this embodiment, the other side of the housing 2 is fixedly connected with a mounting plate 6. An opening 7 is formed inside the mounting plate 6. The flipping mechanism 5 includes a second motor 51. The second motor 51 is installed inside the housing 2. The output end of the second motor 51 is fixedly connected with a first gear 52. The first gear 52 meshes with an external gear ring 53. The inner side of the external gear ring 53 is fixedly connected with a first ring plate 54. The other side of the first ring plate 54 is rotatably connected with the mounting plate 6. Two support assemblies 55 are arranged on one side of the first ring plate 54. The support assembly 55 includes two connecting rods 551. The other ends of the two connecting rods 551 are fixedly connected with the first ring plate 54 together. A second fixing plate 552 is fixedly connected between the two connecting rods 551. Two symmetric L-shaped plates 553 are fixedly connected to the rear end of the second fixing plate 552. The outer side of the connecting rod 551 is movably connected with a second ring plate 56. A clamping groove 57 is formed inside the second ring plate 56. The clamping groove 57 fits the surface of the connecting rod 551.

[0025] Specifically, start the second motor 51 to drive the first gear 52 to rotate. The first gear 52 meshes with the external tooth ring 53, thereby promoting the rotation of the first ring plate 54. At the same time, it will drive a plurality of connecting rods 551 to rotate with the first ring plate 54. Then, supported by the L-shaped plate 553, the H-shaped aluminum tube can be driven to flip.

[0026] In this embodiment, a third fixing plate 58 is fixedly connected to the inner side of the second ring plate 56. A push plate 59 is movably connected to the inner side of the third fixing plate 58. An arc plate 510 is fixedly connected to the upper end of the push plate 59. A ring groove 511 is formed on the outer side of the second ring plate 56. A clamping plate 512 is movably connected to the inner side of the ring groove 511. An extension plate 513 is fixedly connected to the lower end of the clamping plate 512. A sliding plate 514 is fixedly connected to the rear end of the extension plate 513. The lower end of the sliding plate 514 is slidably connected to a rail groove 515. The lower end of the rail groove 515 is fixedly connected to the base 1. A toothed plate 516 is fixedly connected to the rear end of the sliding plate 514. A second gear 517 meshes with the lower end of the toothed plate 516. A second belt pulley 518 is fixedly connected to the rear end of the second gear 517. The rear end of the second belt pulley 518 is rotatably connected to the first fixing plate 43. A belt 519 is rotatably connected to the outer sides of the second belt pulley 518 and the first belt pulley 44.

[0027] Specifically, the first belt pulley 44 and the belt 519 drive the second belt pulley 518 to rotate, thereby causing the second gear 517 to rotate simultaneously. Then, the second gear 517 meshes with the toothed plate 516 to move it in the direction of the conveyor belt 11. Then, through the connection between the sliding plate 514 and the extension plate 513, the clamping plate 512 and the second ring plate 56 move together, and under the connection of the push plate 59, the H-shaped aluminum tube can be pushed in the direction of the laser cutting head 3.

[0028] In this embodiment, a third ring plate 520 is fixedly connected to one end of the connecting rod 551. Two support frames 521 are fixedly connected to the inner side of the third ring plate 520. A coating tank 8 is arranged on the outer side of the housing 2. A spray head 9 is installed at the lower end of the coating tank 8. The lower end of the spray head 9 extends to the inner side of the housing 2. A stopper 522 is movably connected to the lower end of the spray head 9. A fixing rod 523 is fixedly connected to one side of the stopper 522. The fixing rod 523 is fixedly connected to the third ring plate 520.

[0029] Specifically, during the flipping process of the H-shaped aluminum tube, since the third ring plate 520 is fixed to the connecting rod 551, the third ring plate 520 will also rotate with the H-shaped aluminum tube. Thus, the stopper 522 rotates and moves away from the lower end of the spray head 9, enabling the antireflection film agent in the coating tank 8 to be sprayed on the surface of the H-shaped aluminum tube through the spray head 9.

[0030] In this embodiment, two groups of vertical rods 10 are fixedly connected to the lower end of the first grinding plate 47. The lower ends of the two groups of vertical rods 10 are jointly fixedly connected to the base 1, and a conveyor belt 11 is rotatably connected between the two groups of vertical rods 10.

[0031] Specifically, after the H-shaped aluminum pipe section is placed on the conveyor belt 11, the electric push rod 464 is started again to push the clamping plate 465 so that the clamping rod 467 is removed from the hole of the H-shaped aluminum pipe section, and the H-shaped aluminum pipe section can be removed from the housing 2 under the transportation of the conveyor belt 11.

[0032] During use, first place the H-shaped aluminum pipe with holes on both sides in the inner area of the opening 7, and then place both sides of the H-shaped aluminum pipe into the L-shaped plate 553. During the pushing process, the cross beam of the H-shaped aluminum pipe will squeeze the arc plate 510, causing the push plate 59 to move downward to the inner side of the third fixing plate 58. After the entire H-shaped aluminum pipe is placed inside the housing 2, the arc plate 510 is no longer subjected to the extrusion force, and the push plate 59 pops out from the inner side of the third fixing plate 58 and blocks one end of the H-shaped aluminum pipe. At this time, the other end of the H-shaped aluminum pipe is already below the paint can 8 and the nozzle 9, and then the second motor 51 can be started to drive the first gear 52 to rotate. The first gear 52 meshes with the external tooth ring 53, thereby promoting the rotation of the first ring plate 54. At the same time, it will drive a plurality of connecting rods 551 to rotate along with the first ring plate 54. Then, under the support of the L-shaped plate 553, the H-shaped aluminum pipe is driven to flip together. During the flipping process, since the third ring plate 520 is fixed to the connecting rod 551, the third ring plate 520 will also rotate along with the H-shaped aluminum pipe, so that the stopper 522 rotates and moves away from the lower end of the nozzle 9, and the anti-reflection film agent in the paint can 8 is sprayed on the surface of the H-shaped aluminum pipe through the nozzle 9. Subsequently, the second motor 51 stops output, and then the first motor 41 is started to make the rotating rod 42 rotate. During the rotation of the rotating rod 42, on the one hand, two clamping assemblies 46 are driven to flip through the connection of the rotary joint 45, and on the other hand, the second pulley 518 is driven to rotate through the first pulley 44 and the belt 519, so that the second gear 517 rotates simultaneously. Then, the second gear 517 meshes with the toothed plate 516 to make it move in the direction of the conveyor belt 11. Then, through the connection of the sliding plate 514 and the extension plate 513, the clamping plate 512 and the second ring plate 56 move together, and under the connection of the push plate 59, the H-shaped aluminum pipe is pushed to move in the direction of the laser cutting head 3 until the other end of the H-shaped aluminum pipe extends between the two clamping plates 465 and contacts the support block 466 at its lower end. Then, the first motor 41 stops output. Then, two electric push rods 464 closer to the laser cutting head 3 are instructed to start contracting, so that the two clamping plates 465 approach the H-shaped aluminum pipe, and the clamping rods 467 are inserted into the holes opened on both sides of the H-shaped aluminum pipe. After the H-shaped aluminum pipe is fixed, the second motor 51 is started again to flip the H-shaped aluminum pipe. At this time, the laser cutting head 3 starts to perform laser cutting while the H-shaped aluminum pipe is rotating, and the nozzle 9 will spray the surface of the next cutting area of the H-shaped aluminum pipe. The first cut section of the H-shaped aluminum pipe is directly fixed between the two clamping plates 465. Subsequently, the first motor 41 is started again to make the two clamping assemblies 46 continue to flip, so that the clamping assembly 46 with the H-shaped aluminum pipe section is flipped above the conveyor belt 11. During the process, the cross section of the cut H-shaped aluminum pipe section will contact the first grinding plate 47 and the second grinding plate 48 for grinding. After the H-shaped aluminum pipe section is placed on the conveyor belt 11, the electric push rod 464 is started again to push the clamping plate 465 to move the clamping rod 467 out of the hole of the H-shaped aluminum pipe section.The H-shaped aluminum pipe section is then transported by the conveyor belt 11 for the next operation. At this time, the other set of clamping components 46 that have been turned over will do the same as above, and will fix the next H-shaped aluminum pipe section to be cut again, and then the operation is as above, continuing to cut and spray until the H-shaped aluminum pipe material is completely cut into sections.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
