Laser cutting machine with pre-spray water guide structure

Abstract

The invention relates to a laser cutting machine, mainly solving the problems that during the process of machining a tube with a miniature diameter by a laser cutting machine in the prior art, thermal damage is brought to a spare part by generated heat, and scraps are not easily cleaned. The invention adopts the technical scheme that the laser cutting machine comprises a coaxial water jet-flowing device system and a front water guiding system, wherein the motor (1) of the front water guiding system is connected with a water guiding pipe (4) through a coupling (2) and a bushing (3), one end of the bushing (3) is arranged in the coupling (2), the other end of the bushing (3) is connected with the water guiding pipe (4) in a sealing way, a water inlet (6) is arranged on the end of the water guiding pipe (4) close to the bushing (3), the water inlet (6) is connected with the sealed bearing (7) of an automatic water supply system (5), the outer diameter of the water guiding pipe (4) is smaller than the inner diameter of a to-be-processed tube (8), and the end, far away from the bushing (3), of the water guiding pipe (4) is embedded into the inside of the to-be-processed tube. According to the invention, the problems are better solved, and the laser cutting machine can be applied to the industrial production of laser wet cutting processing.

Description

technical field [0001] The invention relates to a laser wet cutting machine with a front spray water guiding structure, in particular to a laser cutting machine with a front spray water guiding mechanism and a coaxial water jet device. 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 la...
