Abstract

The invention relates to a device of a laser cutting machine for replacing same gas source quickly. The device comprises a primary inlet gas circuit, wherein the input port of the primary inlet gas circuit is separately connected to at least two branch inlet gas circuits and the output port are separately connected to at least two branch outlet gas circuits; the input port of each branch inlet gascircuit is connected to a gas source; the output port of each branch outlet gas circuit is connected to the input port of a primary outlet gas circuit and the output port of the primary outlet gas circuit is connected to a laser head; an electromagnetic value of the primary inlet gas circuit and a pressure detection valve of the primary inlet gas circuit are arranged on the primary inlet gas circuit; an adjusting valve of each branch inlet gas circuit and a pressure detection valve of each branch inlet gas circuit are arranged on each branch inlet gas circuit; an electromagnetic valve of thebranch outlet gas circuit and a one-way valve of the branch outlet gas circuit are arranged on each branch outlet gas circuit; each branch inlet gas circuit is connected to the electromagnetic valve of the primary inlet gas circuit; and the adjusting valves of the branch inlet gas circuits, the pressure detection valves of the branch inlet gas circuits, the electromagnetic valve of the primary inlet gas circuit, the pressure detection valve of the primary inlet gas circuit, the electromagnetic valves of the branch outlet gas circuits and the one-way valves of the branch outlet gas circuits areseparately connected to a control system through wires. The device has the advantages of being reasonable in design, switching gas sources automatically, switching gas sources without shot-down and the like.

Description

Technical field: [0001] The invention relates to the technical field of laser cutting machines, in particular to a rapid replacement of the same type of gas source device for a laser cutting machine. Background technique: [0002] For plate processing, compared with traditional mechanical equipment cutting methods, laser cutting machines have the characteristics of high precision, fast cutting, not limited to cutting pattern restrictions, automatic typesetting to save materials, smooth incisions, and low processing costs. With the rapid development of laser applications, users have put forward higher requirements for the production efficiency of laser cutting machines. When cutting metal sheets, laser cutting machines need auxiliary gases (such as oxygen, nitrogen and other gases) for cutting. Although the existing laser cutting machines are equipped with auxiliary gas equipment, they are only controlled by one gas circuit. Whether it is filling gas or hydraulic gas, when t...

Problems solved by technology

Although the existing laser cutting machines are equipped with auxiliary gas equipment, they are only controlled by one gas circuit. Whether it is filling gas or hydraulic gas, when the gas pressure does not meet the cutting requirements and the gas source is switched, the laser cutting machine must stop. Work, time cost increases, reduces work efficiency
