Processing method for laser wet cutting of thin-wall pipes

Abstract

The invention relates to a processing method for laser wet cutting of thin-wall pipes and mainly solves the problems of difficult removal of scraps and heat damage to parts caused by heat generated in the machining process of micro-small-diameter pipes by a laser cutting machine in the prior art. In order to better solve the problems, the processing method for the laser wet cutting comprises the steps of sealing one end of a to-be-cut thin-wall pipe and fixing at a position close to the sealing end by a clamp jacket of the laser cutting machine; inserting a water guide pipe of a water guide system from the other end of the to-be-cut tin-wall pipe; starting the laser cutting machine to enable the to-be-cut pipe to rotate at high speed; starting a front-mounted spraying water guide system of the laser cutting machine to enable the water guide pipe to rotate; starting an automatic water supply system of the front-mounted spraying water guide system to enable high-pressure water to spray out from the water spraying port of the water guide pipe so as to act on a to-be-cut position of the thin-wall pipe; and starting a cutting head of the laser cutting machine to cut the thin-wall pipe. The processing method for the laser wet cutting of the thin-wall pipes can be used in the industrial production of a laser wet cutting process.

Description

[0001] technical field [0002] The invention relates to a laser wet cutting processing method for thin-walled pipes, in particular to a laser wet cutting processing method with a pre-spray water guiding system. 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. 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 melte...
