Description
Technical Field
The utility model relates to a laser cutting machine field, in particular to laser cutting machine gas circuit structure.
Background
The laser cutting machine focuses laser emitted from a laser into a laser beam with high power density through an optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach a melting point or a boiling point, and simultaneously, the high-pressure gas coaxial with the laser beam blows away the molten or gasified metal. And finally, the material is cut along with the movement of the relative position of the light beam and the workpiece, so that the cutting purpose is achieved.
In the use process of the laser cutting machine, three gases are controlled by three electromagnetic valves of three gas pipes at the cross beam of the laser cutting machine, and the three gases are separately controlled, so that the following problems exist:
1. one more electromagnetic valve is needed, so that the cost is increased;
2. because each gas circuit needs to be controlled independently, the processing intensity of the controller is increased, and the control is easy to cause problems;
3. because three solenoid valves and three pipelines are arranged, the space inside the cross beam is increased.
SUMMERY OF THE UTILITY MODEL
In view of the above prior art's shortcoming, the utility model aims to provide a laser cutting machine gas circuit structure with a pipeline of nitrogen gas and air sharing to change three solenoid valves into two solenoid valves, reduced the space promptly and also reduced the cost.
In order to realize above-mentioned purpose and other relevant purposes, the utility model provides a laser cutting machine gas circuit structure, including nitrogen gas source, air supply and oxygen air supply, nitrogen gas source and air supply are connected with a three-way port through first pipeline, the oxygen air supply passes through the second pipeline and is connected with another port of three-way, three-way last port and cutting head tube coupling.
Furthermore, a partition plate quick-insertion straight-through, low-pressure electromagnetic valve and a low-pressure proportional valve are arranged between the oxygen gas source and the tee joint on the second pipeline.
Furthermore, the first pipeline comprises branch pipelines and a main pipeline connected with the branch pipelines, wherein the branch pipelines comprise two pipelines, one end of each branch pipeline is respectively connected with a nitrogen gas source and an air gas source, the other end of each branch pipeline is respectively connected with one port of a pipeline tee joint, the main pipeline is connected with the other port of the pipeline tee joint, and a quick-screwing straight-through and a high-pressure electromagnetic valve are arranged between the pipeline tee joint and the pipeline tee joint of the main pipeline.
Furthermore, two branch pipelines are provided with manual valves.
Furthermore, a one-way valve is arranged between the low-pressure proportional valve and the tee joint on the second pipeline.
Furthermore, a one-way valve is arranged between the high-pressure electromagnetic valve and the tee joint on the first pipeline.
Laser cutting machine gas circuit structure following beneficial effect has at least:
because nitrogen gas is close to air pressure and flow (the pressure is higher than about 1MPA-2.5 MPA), the gas is switched infrequently during processing, thereby sharing a pipeline with nitrogen gas and air in this application, can save a high-pressure solenoid valve like this, reduce the cost, and also reduced the inside space of crossbeam.
Meanwhile, two manual valves are arranged behind the air source, so that a certain gas can be selectively opened, nitrogen and air can be independently selected in the cutting process, the air output of the nitrogen and the air can be conveniently selected, and the whole control is more accurate and quicker.
