Laser cutting machine

Abstract

The invention relates to a laser cutting machine with a coaxial spray nozzle, and the machine mainly solves the problems in an existing thin-wall pipe laser processing technology that the laser cutting machine can only cut in a dry way or can only cut in a wet way but cannot realize the two processes simultaneously. The laser cutting machine with the coaxial spray nozzle comprises a dust suction module and a water circulation module; the dust suction module comprises a dust collector and a dust suction pipe; the dust suction pipe is connected with a dust suction pipe installation hole (8) in a sealed cavity (7) through a flange; the water circulation module comprises a water collection pipe (10), a sewage filter device (11), a pressurizing water pump (12) and a water guiding mechanism (13); one end of the water collection pipe (10) is connected with a blanking box (9), and the other end of the water collection pipe (10) is connected with the sewage filter device (11); the sewage filter device (11) is connected with the pressurizing water pump (12); the water inlet of the water guiding mechanism is connected with the pressurizing water pump (12); and a water guide pipe and a pipe (3) are inserted into a pipe to be processed. Due to the adoption of the technical scheme, the problems are well solved, and the laser cutting machine can be used in the industrial production of laser dry and wet cutting.

Description

[0001] technical field

[0002] The invention relates to a laser cutting machine with a coaxial nozzle, in particular to a laser cutting machine with a coaxial nozzle which is compatible with thin-walled pipe dry cutting and wet cutting processes. Background technique

[0003] Laser cutting technology is widely used in the processing of metal and non-metal materials due to its advantages of reducing processing time, reducing processing costs and improving workpiece quality, and laser cutting processing is gradually replacing traditional cutting tools.

[0004] Laser micromachining has become the main method for thin-walled pipe processing due to its high processing efficiency, less cutting residue, non-contact processing, and easy automation of the processing process. In laser processing of thin-walled tubes, the wet cutting process usually has an advantage in cutting small parts, because small-sized metal parts will quickly generate heat during cutting, and wet cutting play...
