Description

Technical Field

[0001] This utility model relates to the field of sheet metal cutting technology, and in particular to a slag removal device for cutting metal sheets. Background Technology

[0002] Large-scale laser cutting equipment is an industrial device that uses a high-energy laser beam to precisely cut metallic or non-metallic materials. Its core components include a laser generator, a cutting head, a control system, and a motion platform. The equipment generates high temperatures through a focused laser beam, rapidly melting or vaporizing the material. Assisted gas is used to remove molten slag, achieving high-precision cutting. Large-scale laser cutting equipment features high cutting speed, high precision, and smooth cut edges, making it suitable for cutting and processing sheet metal.

[0003] In practice, the metal sheet needs to be placed on a feed table to keep it horizontal. Then, the feed table feeds the metal sheet into the cutting area of ​​the laser cutting equipment. The feed table consists of N strips with toothed protrusions arranged side-by-side. Because slag is generated during the cutting process, after the assist gas blows it away, a small amount of slag adheres to the strips. After cooling, the slag forms metal particles that adhere to the strips. Over time, the slag gradually accumulates into spherical slag blocks at the toothed protrusions of the strips. This severely affects the flatness of the metal sheet. Therefore, manual cleaning of the slag blocks is required periodically. Although the slag blocks are not tightly adhered and manual cleaning is relatively easy, the strips are long, resulting in a relatively large amount of slag. Furthermore, due to the high density of the strips and the small gaps between adjacent strips, it is necessary to remove the strips, clean them, and then reinstall them. Therefore, manual cleaning is relatively inefficient and cumbersome. Utility Model Content

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] A slag removal device for cutting metal sheets includes: a cleaning structure 1, a transmission structure 2, a power motor 3, and an assembly housing 4. The cleaning structure 1 includes a cleaning plate 11, an assembly plate 12, and a steel brush 13. The assembly plate 12 is n-shaped and straddles a strip. A discharge trough 121 is provided on the assembly plate 12, penetrating the assembly plate 12. Sliding rails are fixedly installed on both sides of the assembly plate 12, and the sliding rails are arranged vertically.

[0019] There are two cleaning plates 11. Each cleaning plate 11 is swayably connected to the side of the assembly plate 12. A torsion spring is provided between the cleaning plates 11 and the assembly plate 12 to bring the cleaning plates 11 closer together. A guide ramp 111 is provided at the end of the cleaning plate 11 away from the assembly plate 12. The guide ramp 111 corresponds to the discharge chute 121. A steel brush 13 is arranged vertically. The steel brush 13 is slidably connected to the assembly plate 12. A positioning screw is provided on the assembly plate 12. The positioning screw passes through the assembly plate 12 and the steel brush 13.

[0020] The transmission structure 2 includes a transmission rod 21 and a transmission disc 22. The transmission rod 21 is arranged vertically. One end of the transmission rod 21 is eccentrically connected to the transmission disc 22. The other end of the transmission rod 21 is oscillatingly connected to the cleaning plate 11. The output end of the power motor 3 is connected to the transmission disc 22.

[0021] The assembly housing 4 has a cavity inside to accommodate the transmission structure 2 and the power motor 3. The cleaning plate 11 protrudes from the assembly housing 4. The assembly housing 4 is equipped with a sliding plate 41 and an operating lever 42. The sliding plate 41 is horizontally positioned and located on both sides of the assembly housing 4. The operating lever 42 is sway-connected to the assembly housing 4. Simultaneously, the assembly housing 4 also has a groove corresponding to the slide rail of the assembly plate 12, restricting the assembly plate 12 to move only vertically. It is worth noting that, in practice, the assembly housing 4 has a through hole for assembling the power supply line of the power motor 3, enabling the power motor 3 to operate normally.

[0022] In practical applications, this device is mounted on a material platform, ensuring that the sliding plate 41 is in contact with the slats of the platform. Simultaneously, the assembly plate 12 is placed across the slat to be cleaned. At this point, the two cleaning plates 11 are positioned on either side of the slat. Furthermore, because a torsion spring is provided between the cleaning plate 11 and the assembly plate 12, the end of the cleaning plate 11 with the guiding inclined surface 111 is fully in contact with the side wall of the slat under the force of the torsion spring. In this state, the steel brush 13, along with the cleaning plate 11, is in contact with the slat.

[0023] After placement, the power motor 3 is started. Driven by the power motor 3, the transmission disc 22 rotates continuously, thereby driving the transmission rod 21 to move synchronously. Since one end of the transmission rod 21 is eccentrically connected to the transmission disc 22, and the other end is oscillatingly connected to the assembly plate 12, the transmission rod 21 can push the assembly plate 12 to reciprocate vertically during the rotation of the transmission disc 22. Thus, the assembly plate 12 can drive the cleaning plate 11 to move vertically relative to the strip. During the movement of the cleaning plate 11, under the action of the torsion spring, the cleaning plate 11 maintains a tendency to move closer to the strip. The attached slag is mostly spherical in shape and has irregular curved surfaces. Therefore, the cleaning plate 11 can scrape off the slag during the movement. The scraped-off slag blocks slide along the cleaning plate 11 under the guidance of the guide slope 111 and finally leave the device through the discharge chute 121. Thus, it can effectively prevent excessive accumulation of slag at the cleaning plate 11, which would affect the normal operation of the cleaning plate 11.

[0024] While the power motor 3 is running, the operator holds the control lever 42. By pushing the control lever 42, the device can slide along the slats, allowing the cleaning plate 11 to clean the entire slat. Simultaneously, while the cleaning plate 11 is removing slag, the steel brush 13 continuously performs a secondary cleaning of the slat after slag removal to remove any remaining slag. Once one slat is cleaned, the operator places the device on another slat and repeats the process to clean all the slats on the platform.

[0025] On the other hand, as the usage time increases, the steel brush 13, being relatively soft, is prone to wear and deformation during use. When the steel brush 13 is no longer able to perform its cleaning function, the positioning screws on the mounting plate 12 are removed, allowing the steel brush 13 to be detached from the mounting plate 12 and replaced with a new steel brush 13.

[0026] In summary, workers only need to push the operating lever 42 to clean the entire slat using this device, greatly reducing their workload. Furthermore, there is no need to disassemble the slat. This effectively improves slag removal efficiency. On the other hand, based on the aforementioned operating process, the cleaning plate 11 cleans the slat from bottom to top. That is, the cleaning plate 11 scrapes off the molten slag from below. During this process, the reaction force exerted by the molten slag on the cleaning plate 11 causes the device to further press against the material platform. This effectively avoids the adverse effects of vibration generated during slag removal on the material platform.

[0027] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
