[0002] In modern industrial manufacturing, H-beams are widely used in building structures, machinery manufacturing, bridge engineering, and many other fields due to their reasonable cross-sectional shape and strong load-bearing capacity. The processing accuracy and efficiency of H-beams directly affect the quality and production progress of subsequent products. Among them, laser cutting, as a high-precision and high-efficiency processing method, has gradually become the mainstream technology for H-beam processing. In practical applications, most existing H-beam laser cutting equipment only has a single cutting function. After the H-beam is cut, it needs to be transferred to an independent laser marking workbench for marking processing by manual handling or additional conveying equipment. This segmented operation mode not only increases the process connection time but also reduces the overall production efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies. In practical applications, most existing H-beam laser cutting devices only have a single cutting function. After the H-beam is cut, it needs to be manually transported or transferred to an independent laser marking workbench for marking processing using additional conveying equipment. This segmented operation mode not only increases the process connection time but also reduces the overall production efficiency. This invention provides an H-beam laser cutting device.

The moving table of the supporting structure can be adjusted in position via moving wheels, and the supporting plate can slide along a sliding groove to adapt to the support requirements of H-beams of different lengths. The fixing component, through the cooperation of the pushing plate and the longitudinal moving plate, achieves stable fixation after the moving table is adjusted into position, preventing the supporting structure from shaking during processing and affecting accuracy. Overall, this improves the efficiency and processing quality of H-beam laser cutting. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] like Figure 1-4As shown, this utility model provides a technical solution: an H-beam laser cutting device, including a cutting body 1, a conveying structure 2 at the bottom of the cutting body 1, a supporting structure 3 on one side of the conveying structure 2, a crossbeam 11, a first lifting stop 12 movably connected to one side of the crossbeam 11, a first flexible moving plate 13 fixedly connected to the other side of the crossbeam 11, a laser cutting device 14 slidably connected to the outer surface of the first flexible moving plate 13, a lifting electromagnetic chuck 15 on one side of the first flexible moving plate 13, a second flexible moving plate 16 on one side of the first flexible moving plate 13, and a laser cutting device 14 slidably connected to the outer surface of the crossbeam 11 on one side of the second flexible moving plate 16. A laser marking device 17 is slidably connected to the outer surface of the flexible moving plate 16. A second lifting baffle 18 is provided on one side of the second flexible moving plate 16. One side of the second lifting baffle 18 is movably connected to the outer surface of the cross frame 11. The conveying structure 2 includes a conveying bracket 21. A conveying roller 22 is rotatably connected to the inner wall of the conveying bracket 21. A feeding plate 23 is provided on one side of the conveying bracket 21. The support structure 3 includes a moving table 31. A moving wheel 32 is fixedly connected to the bottom of the moving table 31. A sliding groove 33 is opened on the top of the moving table 31. A support plate 34 is slidably connected to the inner wall of the sliding groove 33. The moving table 31 is located on one side of the conveying bracket 21. A fixing component 35 is provided at the bottom of the moving table 31.

[0028] In this embodiment, a conveying structure 2 is provided to facilitate the conveying of H-beams to the laser cutting equipment 14 and the laser marking device 17 via a conveying roller 22. The conveying roller 22 is driven to rotate by a drive motor. Specifically, the steel material moves from right to left, triggering a sensor. The first lifting baffle 12 descends, and the lifting electromagnetic chuck 15 descends simultaneously and is energized. After the steel material reaches the position of the first lifting baffle 12, the left wing plate of the steel material is attracted by the lifting electromagnetic chuck 15, and the generated signal is fed back to the PLC. The PLC feeds back a signal to the laser cutting equipment 14 to cut the steel. After cutting is completed, a signal is sent to the PLC, and the PLC sends a signal to the first lifting baffle 12. The lowering bar 12 rises, simultaneously demagnetizing and raising the lifting electromagnetic chuck 15. The cut steel continues to move forward, while the second lifting bar 18 descends. After the cut steel is blocked by the second lifting bar 18, it waits for the cutting to be completed before being grouped and sequentially laser-marked by the laser marking device 17. After the laser marking is completed, the signal is fed back to the PLC, which sends a signal to the second lifting bar 18 to extend, allowing the steel to continue moving forward. The above operation is continuously repeated. The lifting structure, the two flexible moving plates, the laser cutting equipment 14, and the laser marking device 17 are all existing technologies and will not be described in detail here.

[0029] The additional support structure 3 places the steel material on top of the support plate 34, so that the steel material can be moved to one side of the conveyor roller 22. That is, the moving table 31 moves by the moving wheels 32 at the bottom. After moving to one side of the conveyor roller 22, the fixing component 35 is released, and the support plate 34 is pushed to slide in the sliding groove 33 until the bottom of the support plate 34 is on the surface of the conveyor roller 22. The inner wall of the sliding groove 33 is polished, making it easier to push.

[0030] Example 2

[0031] like Figure 3-4 As shown, the fixing component 35 includes a support block 351. The top of the support block 351 is fixedly connected to the inner wall of the movable table 31. A moving hole is opened on the outer surface of the support block 351. A push plate 352 is slidably connected to the inner wall of the moving hole. A push inclined surface 353 is provided at one end of the push plate 352. Lower limit openings are opened on both sides of the push plate 352. Limit blocks 354 are slidably connected to the inner wall of the limit openings. One side of the limit block 354 is fixedly connected to the outer surface of the push plate 352. A longitudinal groove is opened at the top of the moving hole. A longitudinal moving plate 355 is slidably connected to the inner wall of the longitudinal groove. The bottom of the longitudinal moving plate 355 is attached to the outer surface of the push plate 352. The longitudinal groove extends to the bottom of the support plate 34.

[0032] In this embodiment, by setting the fixing component 35, the support plate 34 can be simply positioned on the inner wall of the sliding groove 33 to prevent the support plate 34 from moving when the moving table 31 is pushed. That is, the push plate 352 is pushed forward, and its pushing inclined surface 353 is attached to the bottom of the longitudinal moving plate 355. The bottom of the longitudinal moving plate 355 is also provided with an inclined surface, which can slide in contact with the pushing inclined surface 353. Under the drive of the pushing force, the longitudinal moving plate 355 moves upward into the longitudinal groove. Continue to push until the limiting block 354 is stuck at the front end of the limiting port. The limiting block 354 prevents the push plate 352 from disengaging from the inner wall of the support block 351.

[0033] Working principle:

[0034] like Figure 1-4As shown, in practical application, after placing the H-beam to be processed on the top of the support plate 34, the push plate 352 is pushed forward, and its push inclined surface 353 is attached to the bottom of the longitudinal moving plate 355. The bottom of the longitudinal moving plate 355 is also provided with an inclined surface, which can slide in contact with the push inclined surface 353. Driven by the thrust, the longitudinal moving plate 355 moves upward into the longitudinal groove. Continue pushing until the limiting block 354 is stuck at the front end of the limiting port. The moving table 31 moves by the moving wheels 32 at the bottom. After moving to the side of the conveying roller 22, it is on the conveying roller 22 of the conveying structure 2. The conveying roller 22 is driven by the drive motor to rotate, thereby driving the H-beam to move along the conveying direction. When the H-beam moves to below the cutting body 1, the first lifting stop bar 12 descends to limit the H-beam. Simultaneously, the lifting electromagnetic chuck 15 descends and is energized to generate magnetic force, adsorbing the left wing plate of the H-beam to ensure its stability during the cutting process. Subsequently, the laser cutting equipment 14 can slide along the outer surface of the first flexible moving plate 13 to perform precise cutting of the H-beam according to the preset program. After the cutting is completed, the first lifting baffle 12 rises, the lifting electromagnetic chuck 15 is de-energized and reset, and the cut H-beam continues to move forward with the conveyor roller 22. When the H-beam moves to below the laser marking device 17, the second lifting baffle 18 descends to position it, and the laser marking device 17 slides along the second flexible moving plate 16 to complete the marking process of the cut H-beam. After the marking is completed, the second lifting baffle 18 rises, and the H-beam is finally conveyed to the designated collection area via the unloading plate 23.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
