Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically to a sheet metal laser cutting worktable with integrated dust removal function. Background Technology

[0002] In the field of sheet metal processing, laser cutting has become the core cutting process for sheet metal forming due to its advantages such as high cutting precision, small heat-affected zone, and high processing efficiency. The laser cutting worktable, as a key component supporting the sheet metal parts and cooperating with the cutting head, directly determines the processing quality and the workshop working environment. Currently, most mainstream sheet metal laser cutting worktables on the market adopt a split design of "worktable body + external dust removal equipment" to achieve dust removal during the laser cutting process.

[0003] For example, utility model patent with publication number CN222902936U discloses a laser cutting worktable, including a body.

A collection device for collecting the workpiece is slid into the bottom of the rear end of the body. Dust collection devices are installed on both the left and right sides of the body. The dust collection devices cooperate with the collection devices. A pusher device that cooperates with the support structure is installed on the top of the body.

[0004] The laser cutting worktable provided by the aforementioned patent can adsorb particles and fumes generated during the cutting process. However, this type of worktable is designed for large laser cutting equipment, and its dust collection device is not suitable for small laser cutting equipment. This results in small laser cutting equipment worktables often lacking dust collection mechanisms, leading to a significant amount of dust and fumes being released into the air during operation, which is detrimental to the health of workers.

[0036] like Figure 1 and Figure 2 As shown, it also includes a guide rod 7. The top of both sides of the worktable body 1 are provided with mounting grooves 13. The mounting grooves 13 are provided with multiple mounting holes 14. The two ends of the guide rod 7 are fixed inside the mounting grooves 13 by bolts.

[0038] Working principle: The worktable body 1 is connected to the laser cutting head of the laser cutting equipment. The laser cutting head is adjusted to move on the worktable body 1, and then the workpiece to be cut is placed on the worktable body 1. Then, the laser cutting head is controlled to perform laser cutting on the workpiece. At the same time, the tray 3 and the protective plate 4 form a double protection structure. The conical shape 41 on the surface of the protective plate 4 can enhance the protection effect. The ceramic coating can quickly disperse the heat generated by cutting due to its high thermal conductivity to avoid local overheating. The spring 42 on the bottom surface can also absorb the mechanical stress brought by the laser impact and extend the service life of the protective plate 4. The tray 3 can be easily installed and removed through the pull-out port 10 at the front of the worktable body 1 for easy handling of cutting waste. The support legs 16 and reinforcing rods 17 at the bottom of the worktable body 1 work together to ensure overall stability. The guide rods 7 at the top of both sides are fixed by the mounting grooves 13, mounting holes 14 and bolts, providing auxiliary stability for operation. The dust removal system uses a fan 5 at the bottom of the workbench body 1 as its power source. The fan 5 is fixed to the reinforcing rod 17 by bolts and bottom fixing feet 53. Its suction end is connected to the sleeve 61 of the filter assembly 6 via a suction pipe 52. The filter element 63 in the filter assembly 6 is threadedly connected to the cover 62 via a top connecting ring 631 and inserted into the sleeve 61.

The top of the cover 62 is connected to the dust suction pipe 15 on the back of the workbench body 1 via an outer pipe 622, an outer cap 623, and a connecting pipe 151. The dust suction pipe 15 is also connected to the workbench body. The dust collection ports 11 on both sides of the main body 1 are connected. The air distribution plate 2 at the dust collection port 11 is engaged in the slot 12 by the clamping edge 23. The air distribution holes 22 on the surface can make the dust collection airflow uniform. When the fan 5 is started, a negative pressure will be formed at the dust collection port 11. The dust and smoke generated by laser cutting are drawn into the dust collection port 11. After being evenly distributed by the air distribution plate 2, they enter the filter assembly 6 through the dust collection pipe 15. The dust is intercepted and filtered by the filter element 63. The filtered clean air is finally discharged from the exhaust port 51 at the rear end of the fan 5, thus realizing the efficient removal of sheet metal laser cutting operations and dust and smoke at the same time.

[0039] In summary, compared with the prior art, this application provides a tray 3 inside the workbench body 1, and a protective plate 4 inside the tray 3. The protective plate 4 can hold the laser damage tray 3, and the tray 3, together with the protective plate 4, can collect the waste generated by laser cutting, making it convenient for centralized treatment of the waste generated by cutting. At the same time, dust suction ports 11 are provided on both sides of the workbench body 1, which, together with the fan 5 and the filter assembly 6, can suck the dust and smoke generated by cutting into the filter assembly 6 for filtration, thereby achieving the purpose of dust collection and avoiding the problem of dust and smoke spreading into the air during the cutting process of small laser cutting equipment.
