Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a sheet metal processing and cutting mechanism. Background Art

[0002] Sheet metal fabrication is a comprehensive cold working process for thin metal sheets, encompassing cutting, punching, bending, welding, riveting, die forming, and surface treatment. It is a crucial step in the formation of sheet metal products. Sheet metal cutting is the process of cutting sheet metal into the desired shape and size using various cutting tools or techniques. Cutting methods include mechanical cutting, laser cutting, plasma cutting, and water jet cutting.

[0003] Laser cutting is one of the most common methods of sheet metal cutting. During the laser cutting process, a laser beam is focused on the surface of the sheet metal material through optical elements such as lenses or optical fibers. When the laser beam irradiates the surface of the material, the material absorbs the energy of the laser, causing the local area to rapidly heat up and reach the melting point or boiling point. As the material melts and vaporizes, the laser beam will continue to penetrate downward into the material, forming a narrow and deep incision, thereby achieving cutting.

[0004] Laser cutting has many advantages such as high precision, high speed, good cutting quality, strong material adaptability, and non-contact processing. However, during the laser cutting process, it will generate flying sparks, high-temperature fragments, high-temperature exhaust gas, etc., which will make the laser cutting working environment temperature high. The flying sparks and fragments will pose a threat to the safety of the operator, and there is room for improvement. Utility Model Content
