Description

Technical Field

[0001] The invention relates to a cutting workbench, in particular to a flat plate bevel cutting workbench with an open tabletop. Background Art

[0002] Before welding parts, bevel cutting is required. To stably and reliably support the workpiece, existing cutting tables have dense support points throughout the entire surface. Most use serrated strips, strips, and tips to isolate the interior of the table from the exterior. This structure has the disadvantage that cut waste and iron oxide slag are difficult to drop smoothly and often hang on the table, requiring manual cleaning at all times. Otherwise, long-term accumulation will not only make cleaning difficult, but also reduce the flatness of the cutting platform. The waste can even interfere with the normal placement of the workpiece, seriously affecting cutting quality. Furthermore, iron oxide slag and fine cut waste can pass through the table and fall directly into the interior, making it difficult to clean. Even with a waste collection trough, removing the waste is inconvenient, consuming a significant amount of manpower and time, and impacting overall production efficiency. To address this issue, we provide a flat-panel bevel cutting table with an open surface. Summary of the Invention
