Description

Technical Field

[0002] Stainless steel sheet is a material widely used in many fields such as construction, manufacturing, kitchen utensils, decoration, automotive industry, medical equipment, etc. It is highly favored for its excellent corrosion resistance, good mechanical properties, easy cleaning and beautiful appearance. When stainless steel sheet is actually used, it needs to be cut into different sizes according to the usage.

[0003] The patent document with announcement number CN118455776B discloses a stainless steel plate cutting device, which relates to the field of stainless steel plate processing technology, including a laser cutting machine frame, and a bar groove is symmetrically opened on the upper end of the laser cutting machine frame. Gear shafts are rotatably installed on both side walls of the laser cutting machine frame, and a laser cutting machine controller is fixedly installed on the side wall of the laser cutting machine frame. The fixing mechanism includes an inner bar, and the two inner bars are symmetrically fixed in the inner wall of the laser cutting machine frame respectively. Slide bars are slidably installed inside the two inner bars, and first springs are symmetrically fixed on the side walls of the two slide bars. The two groups of first springs are fixedly connected to the two inner bars at one end away from the slide bar, so that the stainless steel plate can always remain flat, so that the incision can remain flat during operation.

[0018] 3. After the protective cover is lowered, the cooperation between the rack and the third circular gear causes the protective plate to rotate clockwise, thereby releasing the protection of the laser cutting head, ensuring that the laser head can work smoothly during the laser cutting process and avoiding the impact of cutting efficiency due to obstruction by the protective plate.

By installing the protective device 3, the impact of debris on the laser cutting head 27 is effectively blocked or reduced, extending the service life of the equipment and maintaining cutting quality. The protective device 3 includes a second hydraulic chamber 31, which is fixedly connected to the top of the base 1. A third hydraulic rod 32 is slidably connected to the piston at one end of the second hydraulic chamber 31. A round rod 33 is fixedly connected to the top of the third hydraulic rod 32. A rubber ring 34 is fixedly connected to the side of the second hydraulic chamber 31. A fourth hydraulic rod 35 is slidably connected to the piston at one end of the second hydraulic chamber 31. A protective cover 36 is fixedly connected to the bottom of the fourth hydraulic rod 35. A limit plate 37 is fixedly mounted on the outer wall of the first rotating rod 21. This further clarifies the components of the protective device 3, especially the details of the hydraulic system and mechanical structure.

When the protective cover 36 descends, the fifth hydraulic rod 39 on the outer wall of the protective cover 36 is stretched.

The protective device 4 includes a vertical plate 42, which is fixedly connected to the bottom of the base 1. The side of the vertical plate 42 is rotatably connected to a second rotating rod 43 via a bearing. The side of the second rotating rod 43 is fixedly connected to a third circular gear 44. The side of the inner wall of the protective cover 36 is fixedly connected to a rack 41. Through the interaction of the vertical plate 42, the second rotating rod 43, the third circular gear 44 and the rack 41, the position of the laser cutting head 27 can be adjusted or stabilized during the cutting process, providing additional protection and support. The rack 41 and the third circular gear 44 are meshed with each other, and a protective plate 45 is fixedly connected to the side of the second rotating rod 43. Through the meshing relationship between the rack 41 and the third circular gear 44 and the connection between the second rotating rod 43 and the protective plate 45, the protection device 4 can realize its protection function through mechanical transmission, for example, by moving the protective plate 45 to block potential dangers or interference, further enhancing the protection of the laser cutting head 27.

[0032] When the above-mentioned equipment is in use, after the protective cover 36 descends, it drives the rack 41 to descend, the rack 41 drives the third circular gear 44 to rotate, the third circular gear 44 drives the second rotating rod 43 to rotate, and the second rotating rod 43 drives the protective plate 45 to rotate clockwise, thereby releasing the protection of the laser cutting head 27.

[0033] When the above-mentioned device is used in a specific manner, the above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
