Description

Technical Field

[0001] This invention relates to the field of laser cutting equipment technology, and specifically to a novel cutting platform for a high-power optical fiber laser cutting machine. Background Technology

[0002] A laser cutting machine is a processing device that uses a high-power-density laser beam to irradiate the surface of a workpiece, causing the material to melt, vaporize, or reach its ignition point rapidly. Simultaneously, a high-speed airflow removes the molten material, thus achieving the cutting of the workpiece. The laser cutting platform, as an important component of the laser cutting machine, primarily functions to support the workpiece to be cut, provide a path for the laser beam to pass through the workpiece during the cutting process, and support the workpiece to maintain its flatness.

[0003] Existing laser cutting platforms typically use welded steel or cast iron structures for their beds, with several parallel support bars or support saw blades on top for direct contact and support of the material to be cut. However, the following technical problems exist in practical use:

[0004] Uneven wear in certain areas: Due to the nature of the processing tasks, operators often habitually perform cutting operations in a fixed area of ​​the platform. This causes the support saw blade in that area to be directly ablated by the laser beam for a long time, while the support saw blades in other areas of the platform are almost unaffected. This concentrated use in certain areas leads to severely uneven wear on the support saw blades.

[0005] Replacement costs are high: When a local support saw blade fails due to excessive ablation, the entire machine bed needs to be replaced. However, the underutilized areas of the replaced machine bed remain intact, resulting in significant resource waste. For large laser cutting equipment, the overall replacement cost can reach tens to hundreds of thousands of yuan.

[0006] Short maintenance cycle: Frequent complete replacements lead to long equipment downtime, affecting production efficiency and increasing the company's operating costs.

[0007] High-power cutting presents significant challenges: As the power of fiber lasers continues to increase, the ablation effect of the laser beam on the supporting saw blade becomes more pronounced, and the aforementioned problems are particularly prominent in high-power laser cutting machines.

[0008] Therefore, developing a new type of cutting platform that can achieve localized maintenance, reduce replacement costs, and extend overall service life has significant engineering application value. Summary of the Invention

[0009] The purpose of this invention is to provide a novel cutting platform for a high-power optical fiber laser cutting machine, so as to solve the technical problem that existing laser cutting platforms need to be completely replaced due to severe local support saw blade ablation, resulting in resource waste.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a novel cutting platform for a high-power optical fiber laser cutting machine, comprising a bed body, the bed body comprising multiple horizontally spaced crossbeams and multiple main beams horizontally arranged on top of the crossbeams; further comprising several support saw blades spaced on top of the main beams; the top of the support saw blades is provided with a saw tooth structure; the bottom of the support saw blades and the top of the main beams are provided with a detachable plug-in structure that cooperates with each other; each support saw blade is independently installed on the main beam through the detachable plug-in structure and is configured to be individually removed or replaced from the main beam.

[0011] Preferably, the detachable plug-in structure includes an upper slot disposed at the bottom of the supporting saw blade, and a lower slot disposed at the top of the main beam and cooperating with the upper slot.

[0012] Preferably, the upper slot is a through slot or a non-through slot extending along the length direction of the supporting saw blade; the lower slot is a through slot or a non-through slot extending along the length direction of the main beam.

[0013] Preferably, the tooth tips of the sawtooth structure are inverted V-shaped or arc-shaped, the groove depth between adjacent tooth tips is 15-25mm, and the tooth spacing is 30-50mm.

[0014] Preferably, the supporting saw blade is made of a wear-resistant and heat-resistant material, specifically selected from any one of high-chromium cast iron, heat-resistant cast steel, or copper alloy.

[0015] Preferably, the crossbeams and the main beams are arranged in a grid pattern, with a spacing of 400-600mm between adjacent crossbeams and a spacing of 200-400mm between adjacent main beams.

[0016] Preferably, the spacing between the plurality of support saw blades on the main beam is 50-90mm.

[0017] The beneficial effects of this invention are as follows:

[0018] First, it achieves partial maintainability. By replacing the traditional integrated support structure with multiple independent and detachable support saw blades, when a local support saw blade is damaged by laser ablation, only the damaged support saw blade needs to be replaced or its position swapped with that of a good support saw blade. There is no need to replace the entire machine bed, which greatly reduces maintenance costs.

[0019] Secondly, it significantly extends the overall service life of the platform. Because the support saw blades can be interchanged, support saw blades in areas with low utilization can be reassigned to areas with frequent cutting for continued use, making the wear of all support saw blades more uniform, and extending the overall service life of the platform by 3-5 times.

[0020] Third, it reduces resource waste. It avoids situations where the entire machine bed is scrapped due to partial damage, which aligns with the concepts of green manufacturing and circular economy.

[0021] Fourth, it reduces maintenance costs. As an independent component, the manufacturing cost of the support saw blade is far lower than that of the entire machine bed. Taking a 6-meter-long platform as an example, the replacement cost of the entire machine bed is about 50,000 to 80,000 yuan, while the manufacturing cost of a single support saw blade is only 200 to 500 yuan. Based on replacing 10 severely burned support saw blades every six months, the annual maintenance cost is reduced from the original 50,000 to 80,000 yuan to 4,000 to 10,000 yuan.

[0022] Fifth, it is suitable for high-power laser cutting. The serrated top structure reduces the contact area between the support saw blade and the sheet metal, thus reducing heat conduction; at the same time, the detachable structure allows the support saw blade to be made of high-cost heat-resistant and wear-resistant materials without having to consider the material cost of the overall bed.

[0023] Sixth, installation and maintenance are convenient. The plug-in structure, combined with end fasteners, makes the replacement of the support saw blade simple and quick. The replacement time for a single support saw blade is no more than 5 minutes, which greatly reduces equipment downtime. Attached Figure Description

[0029] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] according to Figure 1 , Figure 2 , Figure 3 As shown, a new type of cutting platform for a high-power optical fiber laser cutting machine is composed of two parts: the bed body and the independent detachable support saw blade 3.

[0031] The bed body adopts a grid-like rigid frame, including crossbeams 1 and main beams 2. The crossbeams 1 are arranged in multiple horizontally at equal intervals, with the distance between adjacent crossbeams 1 being 400 to 600 mm. The main beams 2 are arranged in multiple horizontally at equal intervals on top of the crossbeams 1, intersecting the crossbeams 1 perpendicularly to form a grid, with the distance between adjacent main beams 2 being 200 to 400 mm. The support saw blades 3 are independent strip-shaped components, with several equally spaced strips arranged on top of the main beams 2, and the distance between adjacent support saw blades 3 being 50 to 90 mm. The main beam 2 has a lower slot 6 on its top along the thickness direction, and the support saw blade 3 has an upper slot 5 on its bottom along the thickness direction, forming a detachable plug-in structure with the lower slot 6 on the top of the main beam 2; each support saw blade 3 can be installed and removed independently through the plug-in structure without affecting other support saw blades 3; the top of the support saw blade 3 is provided with a saw tooth structure 4, the tooth tip is inverted V-shaped or arc-shaped, the tooth groove depth is 15 to 25 mm, and the tooth spacing is 30 to 50 mm; the support saw blade 3 is made of wear-resistant and heat-resistant material, selected from high-chromium cast iron, heat-resistant cast steel or copper alloy, with high-chromium cast iron being preferred.

[0032] During equipment setup, the crossbeam 1 and main beam 2 are first welded or bolted together to form a stable grid bed. Base plates 7 are located at the bottom of the crossbeams 1 at both ends of the bed body, and these base plates 7 are connected to the equipment frame via mounting holes. The upper slots 5 at the bottom of each support saw blade 3 are aligned with the lower slots 6 at the top of the main beam 2, and pushed in along the length direction to complete assembly. During cutting, the sheet metal is placed on the tips of the saw teeth of the support saw blade 3, and the saw tooth structure 4 reduces the contact area and heat conduction. When a local support saw blade 3 is burned or damaged, the damaged support saw blade 3 can be directly pulled out along the slot and replaced with a new one, or its position can be swapped with a support saw blade 3 from a low-wear area for continued use. This design ensures that the replacement time for a single support saw blade 3 does not exceed 5 minutes, without disassembling the bed body.

[0033] As a preferred option in terms of size and materials

[0034] Horizontal beam spacing 1: 500mm; Main beam spacing 2: 300mm;

[0035] Support saw blade spacing 3: 70mm;

[0036] Sawtooth structure 4: Inverted V-shaped tooth tip, tooth depth 20mm, tooth pitch 40mm;

[0037] Material of support saw blade 3: high chromium cast iron.

[0038] In this embodiment, the connection methods and processing techniques not described in detail all adopt conventional technical means in the field to ensure that the platform strength, heat resistance and ease of assembly and disassembly meet the requirements of high-power laser cutting conditions.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
