Wet Laser Cutting Machine

Abstract

The invention relates to a laser cutting machine, which mainly solves the problem of the prior art that the heat damage on parts is caused by the generated heat and chips are difficultly removed when a pipe with small pipe diameter is processed by the laser cutting machine. The laser cutting machine adopts the technical scheme that the laser cutting machine comprises a cutting head and a front water guide system, wherein a motor (1) of the front water guide system is connected with a water guide pipe (4) through a coupling (2) and a bushing (3), one end of the bushing (3) is positioned in the coupling (2), the other end of the bushing (3) is in sealed connection with the water guide pipe (4), one end, near the bushing (3), of the water guide pipe (4) is provided with a water inlet (6), the water inlet (6) is connected with a sealing bearing (7) of an automatic water supply system (5), the outer diameter of the water guide pipe (4) is smaller than the inner diameter of a pipe (8) to be processed, and the end, away from the bushing (3), of the water guide pipe (4) is inserted into the pipe to be processed. The problems are well solved, and the laser cutting machine can be widely applied to the industrial production of laser wet cutting processing.

Description

technical field [0001] The invention relates to a wet laser cutting machine, in particular to a laser cutting machine with a pre-spray water guiding mechanism. Background technique [0002] 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. [0003] 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. The laser cutting of thin-walled pipe is to move the overlapping laser pulse points along the cutting line on the pipe, and at the same time input high pressure oxygen to assist melting and cutting. The material at the laser focus point is melted and gasified, and the slag is blown out by the gas...
