Description

Technical Field

[0001] The utility model relates to the technical field of flame cutting machines, in particular to a slag cleaning device for a numerically controlled flame cutting machine. Background Art

[0002] In the processing of agricultural machinery, flame cutting machines are needed to cut materials. Flame cutting machines are a kind of cutting equipment that uses gas and oxygen or gasoline and oxygen to cut metal materials. They are mainly used in heavy industry. CNC flame cutting machines are the earliest and best CNC cutting equipment. The introduction of CNC technology into flame cutting has realized the automation of the entire cutting process, significantly improved the cutting quality of steel plate cutting, and has high production efficiency and material utilization.

[0003] Flame cutting machines usually have multiple sword bars installed on the work surface to help support the workpiece to be processed without affecting the processing of the workpiece to be processed. In addition, smaller processing residues can fall directly from between adjacent sword bars. After a period of use, a layer of slag will also adhere to the surface of the sword bars. The presence of slag may make the workpiece unstable during placement, which in turn leads to processing errors and even scrapping of the plate. Therefore, the operator needs to clean the slag on the sword bars regularly. The traditional cleaning method is usually manual cleaning. The operator removes the sword bars from the operating table one by one and grinds them with a grinding wheel or sandpaper. The cleaning is very cumbersome and the cleaning effect is not good.

[0004] Therefore, we propose a slag cleaning device for a CNC flame cutting machine. Utility Model Content
