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 field of cutting, in particular to a multi-hole flame synchronous cutting device. Background technique [0002] Flame cutting, also known as gas cutting, is a process of burning with oxygen and gas flame. In the first step, the temperature of the steel plate must rise to the ignition point. Then, the oxygen flow oxidizes the metal in a narrow and long area, and the slag produced during combustion is cut by the oxygen flow. Blow off to form a cutting seam, and in the process of equipment maintenance or assembly on the electric power site, such as when assembling the cable holding parts in the cable trench, it is necessary to open several holes evenly on the surface of the plate-mounted workpiece. Large holes are usually machined by flame cutting. The processing steps are: first draw lines on the surface of the workpiece, and then use a flame cutter to cut holes one by one. [0003] At present, when processing, if a single ...
