A self-mixing gas supply system for axial fast flow laser

Abstract

A self-mixing gas supply system for an axial fast flow laser, the system includes: a gas mixing bottle, the air inlet of which is connected to the gas outlet of the gas storage bottle for each component gas of the gas required for the operation of the axial fast flow laser; A buffer gas cylinder, the air inlet of which is connected to the gas outlet of the mixed gas cylinder via the first switch device, and the gas outlet is connected to the axial fast flow laser; the first pressure detection device is used to detect the pressure in the buffer gas cylinder. air pressure; and a control device, connected with the first pressure detection device and the first switch device, for controlling the components when the air pressure in the buffer gas cylinder is lower than a first preset value The gas is input into the gas mixing bottle to form the required mixed gas, and the gas in the gas mixing bottle is controlled to be input into the buffer gas bottle, so as to realize the process of automatic gas distribution and gas exchange without shutting down.

Description

technical field [0001] The invention relates to an axial fast flow laser, in particular to a self-mixing gas supply system for an axial fast flow laser. Background technique [0002] Axial Fast Flow CO 2 The laser was born in the early 1970s and got its name from its fast-flowing gas cooling technology coaxial with the beam direction. Due to its good beam quality, high power, stable and reliable operation, it quickly became the mainstream of industrial cutting lasers. So far the international CO2 from 0.5kW to 4kW 2 Almost all laser cutting systems use axial fast flow CO 2 laser. [0003] When the axial fast flow laser works, it needs to continuously input a certain proportion of mixed gas, so the gas supply system of the mixed gas is an important part of the axial fast flow laser. The commonly used laser gas supply system is to directly connect the proportionally prepared gas supply cylinder to the axial fast flow laser. Laser users often purchase mixed gases during us...

AI Technical Summary

Problems solved by technology

The commonly used laser gas supply system is to directly connect the proportionally prepared gas supply cylinder to the axial fast flow laser. Laser users often purchase mixed gases during use. The price is high and the proportion of each component gas in the mixed gas Occasional fluctuations due to external supplier service quality constraints, resulting in poor laser operation

In addition, it needs to stop when changing the gas cylinder, which affects the production efficiency and processing quality of the axial fast flow laser
