Description

Technical Field

[0001] This invention relates to the field of steel plate laser cutting technology, specifically to a cutting device for building steel structure panels. Background Technology

[0002] In steel structures, steel plates need to be cut before they can be used. Due to the large size of the steel plates, laser cutting machines are usually used to meet the cutting requirements.

[0003] Currently, there are many technical bottlenecks when using existing laser cutting machine tools to cut steel plates. The worktable of traditional laser cutting machine tools is generally a fixed structure, and it is mostly composed of multiple parallel racks. Although this structural design can reduce the contact area between the steel plate and the worktable to a certain extent and reduce the impact of thermal deformation during the cutting process, it also brings difficulties in subsequent part removal.

[0004] In actual production, the cut steel plates are laid directly on the workbench. Because the workbench is typically large (common sizes can reach 3m x 6m or even larger), and there is friction between the cut product and the toothed rack, slight adhesion may occur in some cases due to the high temperature of the cutting process. Workers cannot remove the products by hand and must use auxiliary equipment such as magnetic tools and vacuum suction cups. During operation, the magnetic suction points or vacuum adsorption areas must be accurately located first, and then the products must be gradually separated. This entire process not only consumes a significant amount of manpower and time but also carries the risk of scratching or deforming the product surface due to improper operation.

[0005] Furthermore, the existing work mode strictly follows the "part-loading" sequence; only after the cut product has been completely removed can a new plate to be processed be placed on the worktable. This single-operation process results in a significant amount of idle waiting time for the machine tool, severely impacting overall production efficiency. According to industry statistics, when using traditional laser cutting machine tools for steel plate processing, the idle time caused by part-loading and loading can account for more than 30%. At the same time, frequent part-loading operations can introduce human error, leading to a decrease in product qualification rate of approximately 5%-8%.

[0006] Furthermore, to meet the cutting needs of longer steel plates, existing laser cutting machines are typically equipped with large-area worktables to fully support the steel plates to be cut. While this design ensures the feasibility of cutting longer steel plates to some extent, it significantly increases the purchase cost of laser cutting machines, increasing the upfront investment pressure on enterprises. At the same time, the inspection and maintenance of large-area worktables are more complex and cumbersome during equipment maintenance, further increasing the operating costs of enterprises.

Detailed Implementation In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: Example 1 like Figure 1-3 As shown, to facilitate the unloading of products after steel plate cutting, this embodiment provides a new device for steel plate cutting. The device includes a frame 1, a laser cutting mechanism 2, a conveying and supporting mechanism 3, and an unloading mechanism 6. The laser cutting mechanism 2 is adjustablely positioned above the frame 1, meaning it can move along the length of the frame 1 as needed and control the laser cutting head 27 to move in three-dimensional space, providing support for the steel plate cutting process. The conveying and supporting mechanism 3 is located inside the frame 1, and its upper side is flush with the upper sides of both ends of the frame 1. After the steel plate is placed on the conveying and supporting mechanism 3, it can be cut by the laser cutting mechanism 2. After removing the skeleton from the cut steel plate, the conveying and supporting mechanism 3 can transport multiple cut products to the unloading mechanism 6. The unloading mechanism 6 then transports the cut products to the outside of the device, facilitating collection and organization by staff.

[0026] like Figure 5 As shown, to enable laser cutting of steel plates, the laser cutting mechanism 2 includes a laser generator 23 and a laser cutting head 27, both of which are publicly disclosed and connected. The laser generator 23 is the power source for generating laser beam energy to cut the material and is the core component of the laser cutting machine. The laser cutting head 27 includes components such as a focusing lens, a lens, a sensor, and a nozzle. The laser beam is irradiated onto the material surface through the cutting head for processing. The laser generator 23 and the laser cutting head 27 are located on opposite sides of a support frame 24 composed of two parallel plates, and the laser generator 23 is directly connected to the support frame 24. The laser cutting head 27 is directly mounted on a vertical rail. The vertical rail is located between multiple guide wheels 26 on the same side of the support frame 24, and a second lead screw mounted on the side of the vertical rail is threaded through a threaded sleeve mounted on the support frame 24. The end of the second lead screw is connected to the power output shaft of a third motor 28.

[0027] like Figure 5 As shown, a guide rail 25 is provided through multiple guide wheels 26 inside the support frame 24. A first lead screw 22 is provided on the side of the guide rail 25. The end of the first lead screw 22 is connected to the power output shaft of the second motor 21, and the first lead screw 22 is threaded through another threaded sleeve installed on the support frame 24. With the cooperation of the first lead screw 22 and the second lead screw, the laser cutting head 27 can be controlled to move in two-dimensional space.

[0028] like Figure 4 , Figure 5As shown, to further increase the movement range of the laser cutting head 27, both ends of the guide rail 25 are connected to the movable plate 12 mounted on the frame 1. The bottom of the movable plate 12 is movably connected to the frame 1, which can be set with reference to the connection method of the support frame 24 and the guide rail 25, or a linear guide rail can be used to connect the movable plate 12 and the frame 1. A third lead screw is threaded through the threaded sleeve at the bottom of the movable plate 12, and the end of the third lead screw is connected to the power output shaft of the first motor 11. With the third lead screw present, it can cooperate with the first lead screw 22 and the second lead screw to control the movement of the laser cutting head 27 in three-dimensional space, providing support for steel plate cutting.

[0029] To improve cutting quality and ensure equipment safety, auxiliary gas supply systems, cooling systems, and dust and fume extraction systems can be installed. The auxiliary gas supply system includes gas cylinders (oxygen, nitrogen, compressed air), a gas purifier, and a pressure regulating valve. The gas type is selected based on the material being cut (e.g., oxygen for combustion when cutting metal, nitrogen for protective cutting of stainless steel). The cooling system includes a chiller (water circulation cooling) to reduce the temperature of the laser and cutting head, preventing overheating damage (e.g., the discharge tube of a CO2 laser requires strict temperature control). The dust and fume extraction system includes a vacuum cleaner and exhaust ducts to collect smoke and exhaust gases generated during the cutting process, ensuring a safe working environment.

[0030] like Figure 6 , Figure 7 As shown, in order to support the steel plate and realize the unloading of the cut product, the conveying and supporting mechanism 3 includes multiple central shafts 32 and multiple turntables 31. Each central shaft 32 is arranged along the width direction of the frame 1, and the multiple central shafts 32 are evenly distributed along the length direction of the frame 1. The multiple turntables 31 are evenly fitted on the multiple central shafts 32, and the distance between two adjacent central shafts 32 is less than the diameter of the turntable 31. Therefore, the turntables 31 of two adjacent central shafts 32 are staggered, and when viewed along the axial direction of the central shaft 32, the turntables 31 of two adjacent central shafts 32 partially overlap. This arrangement not only allows the steel plate to be stably placed by the cooperation of multiple turntables 31, but also allows the movement of the cut product to be controlled by the rotation of the turntables 31.

[0031] like Figure 8 , Figure 9 As shown, to ensure stable installation of the turntable 31 relative to the central shaft 32, a groove 321 is provided on the central shaft 32 along its length, and the end of the groove 321 is open. A through hole 311 is provided at the center of the turntable 31, and a protruding post is fixedly provided on the inner side wall of the through hole 311. When the turntable 31 is fitted onto the central shaft 32, the protruding post is located in the groove 321. This arrangement allows the central shaft 32 and the turntable 31 to rotate synchronously during assembly.

[0032] like Figure 8 , Figure 10, Figure 11 As shown, furthermore, through holes 322 are provided at both ends of the central shaft 32, and a stop ring plate 36 and an adjusting device 33 are sleeved at the end of the central shaft 32. The adjusting device 33 includes a fixed ring plate 335 and an adjustable ring plate 331. A threaded rod 332 provided on the adjustable ring plate 331 passes through the connecting hole 333 of the fixed ring plate 335, and a nut is threaded on the threaded rod 332. The fixed ring plate 335 and the stop ring plate 36 are respectively sleeved on the central shaft 32 by a first connecting bolt 334 and a second connecting bolt 361, and the multiple turntables 31 are located between the adjustable ring plate 331 and the stop ring plate 36. Therefore, by rotating the nut, the position of the adjustable ring plate 331 can be adjusted so that it cooperates with the stop ring plate 36 to press the multiple turntables 31 to remain stationary relative to the central shaft 32.

[0033] like Figure 7 , Figure 12 As shown, to ensure the stable mounting of the central shaft 32 on the frame 1, a bearing seat is fitted at the end of each central shaft 32, and each bearing seat is mounted on the frame 1 via a mounting device 35. Specifically, the mounting device 35 includes a support plate 351, a mounting plate 352, and a mounting plate 353. The mounting plate 352 is fixedly mounted on the side of the support plate 351, and the mounting plate 353 is detachably mounted on the opening at the top of the mounting plate 352 by bolts. Simultaneously, the top of the mounting plate 353 is bolted into the profile that makes up the frame 1, thus ensuring the stable mounting of the central shaft 32.

[0034] like Figure 7 As shown, in order to rotate the central shaft 32, two sprockets 34 are fitted on each central shaft 32. Adjacent central shafts 32 are connected by sprockets and chains. One or more central shafts 32 are connected to the power output shaft of the motor through chains and sprockets. Under the operation of the motor, the central shaft 32 can be controlled to drive the turntable 31 to rotate. Then, with the cooperation of multiple turntables 31, products distributed in different positions are transported to the end of the frame 1.

[0035] like Figure 21 As shown, to facilitate product collection, the unloading mechanism 6 transports the products to a designated location. Specifically, the unloading mechanism 6 includes an annular belt 61 and two first supports 63. The annular belt 61 is arranged along the width direction of the frame 1, and the upper side of the annular belt 61 is lower than the upper side of the conveying and supporting mechanism 3. Support rollers 62 are provided at both ends of the inner side of the annular belt 61. The end shafts of the support rollers 62 are connected to the first supports 63 via bearing seats, and the end shaft of one of the support rollers 62 is connected to a motor via a sprocket and chain. When the motor is working, it can control the rotation of the annular belt 61, moving the products falling on the annular belt 61 to a certain position.

[0036] like Figure 21As shown, in order to support the annular belt 61 to receive steel products, the feeding mechanism 6 also includes a support plate frame 64. The support plate frame 64 is installed between the two first supports 63 and extends into the inner side of the annular belt 61. At the same time, the upper side of the support plate frame 64 contacts the upper side wall of the annular belt 61, which can enhance its ability to receive products.

[0037] like Figure 21 As shown, the first bracket 63 is installed on the bottom beam 78, and the bottom beam 78 is connected to the frame 1, so that the feeding mechanism 6 can be stably installed on the side of the frame 1.

[0038] To control the operation of this device, a corresponding control system can be provided as needed, such as a numerical control system (CNC), an operation panel, and software.

[0039] Example 2 like Figure 7 As shown, based on Example 1, in the case of laser cutting steel plate, molten material will adhere to the turntable 31. In order to facilitate cleaning of the turntable 31, a cleaning mechanism 4 is provided in parallel below each central axis 32.

[0040] like Figure 13 , Figure 14 As shown, specifically, the cleaning mechanism 4 includes two support tubes 42, two sets of bases 43, and multiple sets of cleaning devices 41. The two support tubes 42 are arranged in parallel, and the two sets of bases 43 are respectively located at both ends of the support tubes 42. The insertion rods 431 installed on the top of the bases 43 are inserted into the support tubes 42 by bolts. At the same time, the bottom of the bases 43 are bolted into the profile of the frame 1, so that the support tubes 42 are stably installed on the inner side of the frame 1. The number of cleaning devices 41 is equal to the number of turntables 31 on each central shaft 32, and each cleaning device 41 includes a cleaning plate and a sleeve 412 installed below the cleaning plate. The support tubes 42 pass through the sleeve 412, and the turntables 31 pass through the gaps in the cleaning plates. When the turntables 31 rotate and pass through the cleaning plates, the material adhering to the turntables 31 will be removed from the turntables 31 by impacting the cleaning plates.

[0041] like Figure 15 , Figure 16 As shown, the cleaning plate can be configured as either a first cleaning plate 411 or a second cleaning plate 413. The top of the first cleaning plate 411 is a flat structure, and when the first cleaning plate 411 is fitted onto the turntable 31, it only covers a small area of ​​the turntable 31. The top of the second cleaning plate 413 is a triangular structure, and when the second cleaning plate 413 is fitted onto the turntable 31, its top can be positioned close to the center of the turntable 31. Therefore, the second cleaning plate 413 can cover a larger area of ​​the turntable 31, achieving cleaning over a larger area.

[0042] Example 3 like Figure 1 , Figure 17 As shown, based on embodiment 1 or 2, in order to receive materials falling from above and facilitate cleaning by staff, a collection mechanism 5 is provided on the inner side of the frame 1 and below the cleaning mechanism 4. The collection mechanism 5 receives waste materials generated from steel plate cutting and impurities removed by the turntable 31. In addition, the collection mechanism 5 can be tilted under external force, so that the collected materials can be moved to the same end for staff to clean in a concentrated manner.

[0043] like Figure 18 , Figure 19 As shown, specifically, the collection mechanism 5 includes a collection plate and an intercepting plate 51. The collection plate is configured as an upward-facing U-shaped compartment, and a slot 59 is provided at the end of the inner wall of the collection plate. The edge of the intercepting plate 51 is inserted into the slot 59. When it is necessary to collect and clean up the material, the operator can lift the intercepting plate 51 to clear the end of the collection plate, thereby relieving the accumulation of material and allowing it to slide down.

[0044] To stably install the collecting plate within the frame 1, a base frame 52 is provided below the collecting plate. A connecting shaft 58, inserted at one end corner of the base frame 52, is mounted on a connecting plate 57. The bottom of the connecting plate 57 is bolted into the profile of the frame 1, allowing the collecting plate to be hinged to the frame 1 at this end. The connecting shaft 58, inserted at the other end of the base frame 52, is mounted on a top block 55. One top block 55 has an adjusting screw 56 connected through it via a bearing, while square tubes are fixedly installed below the remaining top blocks 55. Multiple connecting plates 57 are provided below the top blocks 55 and connected to the profile of the frame 1. A support plate 53 is fixedly installed on the side of each connecting plate 57, and a connecting pipe 54 is connected to the side of the support plate 53 via a connecting shaft 58. The adjusting screw 56 is threaded through a nut installed in one of the connecting pipes 54, and the square tubes pass through the remaining connecting pipes 54. With this configuration, once the base frame 52 is stably installed, the tilt angle of the base frame 52 can be adjusted by rotating the adjusting screw 56, thereby tilting the collection plate to facilitate the centralized cleaning of accumulated impurities. Of course, this configuration also allows for easy disassembly of the collection plate to adapt to different needs.

[0045] Example 4 like Figure 1-3 As shown, based on embodiments 1, 2 or 3, in order to cut longer steel plates and avoid the steel plates protruding from the frame 1, which would be detrimental to their stable placement, at least two sets of limiting mechanisms 7 can be set on the same side of the end of the frame 1. Both sets of limiting mechanisms 7 are installed on the bottom beam 78, so that the steel plates can be stably placed on the frame 1 under the action of the limiting mechanisms 7.

[0046] like Figure 20As shown, specifically, the limiting mechanism 7 includes an upper roller 73, a lower roller 72, and two second supports 71. The bottoms of the two second supports 71 are detachably mounted on the bottom beam 78. The ends of the lower roller 72 are connected to the top of the two second supports 71 via bearing seats. The ends of the upper roller 73 are connected to a support device via bearing seats. The bottom of the support device is connected to the second supports 71. Therefore, the support device is adjustable, and the relative positions of the upper roller 73 and the lower roller 72 can be adjusted as needed, thereby clamping steel plates of different thicknesses.

[0047] like Figure 20 As shown, the support device includes a second connecting plate 77 and a first connecting plate 76 distributed vertically. The first connecting plate 76 is mounted on the second bracket 71, and the second connecting plate 77 is mounted on the bearing seat of the upper roller 73. A guide rod 74 and a threaded post 75, fixedly disposed on the side of the first connecting plate 76, pass through the second connecting plate 77. Two nuts are threaded onto the threaded post 75, and the two nuts are distributed on the upper and lower sides of the second connecting plate 77. With the cooperation of the guide rod 74 and the threaded post 75, the upper roller 73 and the lower roller 72 can be relatively stably installed, and the distance between the upper roller 73 and the lower roller 72 can be adjusted by rotating the nuts.

[0048] In addition, a motor can be used in conjunction with the limiting mechanism 7, and the power output shaft of the motor can be connected to the upper roller 73 or the lower roller 72 through a sprocket and chain, so that the movement of the steel plate can be controlled according to the cutting requirements to realize the cutting process of the steel plate.

[0049] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
