Description

Technical Field

[0001] This utility model relates to the field of flame cutting technology, and in particular to a highly safe flame cutting machine. Background Technology

[0002] Flame cutting machines, also known as CNC flame cutting machines, are CNC machines that utilize flame cutting. They preheat the workpiece to its ignition point using the heat generated by the combustion of oxygen and fuel gas (acetylene, propane, liquefied petroleum gas, etc.). A high-speed cutting oxygen stream is then ejected, causing the preheated metal to burn and release heat to further preheat the metal to be cut, thus achieving the cutting process. Primarily used in heavy industry, current flame cutting machines, while meeting normal usage requirements, still have shortcomings in practical application. For example, their protective effect is poor, and sparks easily fly everywhere during cutting, potentially burning workers and posing safety hazards. Therefore, a high-safety flame cutting machine is proposed. Utility Model Content
