Abstract

The invention relates to the field of cutting, and particularly discloses a multi-hole flame synchronous-cutting device which comprises a moving frame, wherein a fixing frame is slidably connected onto the moving frame; a plurality of rotation drivers are arranged on the fixing frame; cutters are correspondingly connected to all the rotation drivers; and a fire-insulating actuator is mounted on the moving frame. Through cascaded fire-insulating columns and a fire extinguisher, the quick fire extinguishing operation on the cutters can be achieved, and the circumstance that a pipeline is damageddue to the backflow of flame to the pipeline can be avoided.

Description

Technical field [0001] The invention relates to the cutting field, in particular to a porous flame synchronous cutting device. Background technique [0002] Flame cutting is also called gas cutting. It is a process of burning with oxygen and gas flame. In the first step, the temperature of the steel plate must be raised to the ignition point. Then, the oxygen flow oxidizes the metal in the narrow area, and the slag produced during combustion is cut by the oxygen flow. Blow away to form a cutting seam. In the process of equipment maintenance or assembly at the power site, such as the assembly of the cable holding parts in the cable trench, it is necessary to evenly open a number of holes on the surface of the board-mounted workpiece. Large, usually flame cutting is used to process holes. The processing steps are: first draw a line on the surface of the workpiece, and then use a flame cutter to perform hole-by-hole cutting. [0003] At present, if a single hole is cut during proces...
