Pre-spray water guiding mechanism for laser wet cutting

Abstract

The invention relates to a front-end spray water guiding mechanism in laser wet cutting machining, and the mechanism mainly solves the problems in the prior art that when laser is used for processing a pipe with a small diameter, the produced heat damages parts and chips are not easily removed. The front-end spray water guiding mechanism comprises a motor (1), a coupler (2), a lining (3), a water guiding pipe (4), an automatic water supply system (5) and a water inlet (6), the motor (1) is connected with the water guiding pipe (4) through the coupler (2) and the lining (3), one end of the lining (3) is arranged in the coupler (2) and the other end of the lining (3) is in sealed connection with the water guiding pipe (4), one end of the water guiding pipe (4) which is close to the lining (3) is provided with the water inlet (6), the water inlet (6) and the automatic water supply system (5) are connected through a seal bearing (7), the outer diameter of the water guiding pipe (4) is less than the inner diameter of a pipe (8) to be processed, and the end of the water guiding pipe (4) which is far from the lining (3) is inserted into the pipe to be processed. Due to the adoption of the technical scheme, the problems are well solved, and the front-end spray water guiding mechanism in laser wet cutting machining can be used in the industrial production of laser wet cutting machining.

Description

technical field [0001] The invention relates to a pre-spray water guiding mechanism for laser wet cutting processing. 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, forming a cutting track on the metal pip...
