The utility model has simple structure, use reliability and maintenance convenience, and gas can be replaced without shutdown, thus ensuring the laser to operate continuously and improving production efficiency and process quality.
Description
Technical field
The utility model relates to feeder, is that a kind of high power axle flows CO soon specifically
2The continuous feeder of laser.
Background technology
The high power axle flows CO soon
2The discharge medium of laser is by CO
2, N
2, three kinds of gases of He form by a certain percentage, usually by the gas cylinder air feed.In order to guarantee normal, efficient, the stable work of laser, need constantly scavenge, and replenish " fresh " gas.When prior art is changed gas cylinder, laser is shut down, not only influence rhythm of production and crudy, and often enter the operating efficiency that tracheae reduces laser because of air.Therefore design a kind of simple in structure, use high power axle reliable, easy to maintenance and that can not shut down ventilation to flow CO soon
2The continuous feeder of laser is very necessary.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, use high power axle reliable, easy to maintenance and that can not shut down ventilation to flow CO soon
2The continuous feeder of laser.
For achieving the above object, the utility model adopts following technical scheme: a kind of high power axle flows CO soon
2The continuous feeder of laser, comprise laser and by gas cylinder, pressure-reducing valve, the air supply channel that unidirectional valve and tracheae are formed, gas cylinder by tracheae successively through pressure-reducing valve and unidirectional valve to the laser air feed, it is characterized in that described air supply channel is a two-way, described two-way air supply channel is switched by electromagnetically operated valve and controller, tracheae before the pressure-reducing valve is provided with pressure switch, tracheae behind the unidirectional valve connects with the input of electromagnetically operated valve, the output of electromagnetically operated valve connects with the inlet end of laser, and described controller is the normally open contact of pressure switch, the interlock circuit that the control coil of electromagnetically operated valve and contactor are formed.
Further, described controller also is provided with audible-visual annunciator.
Further, described electromagnetically operated valve is three two-port valves.
During the utility model work, when the storage pressure of one road air supply channel is higher than set point, the normally open contact closure of pressure switch, the control coil conducting of electromagnetically operated valve, electromagnetically operated valve is opened, this road air supply channel air feed; Simultaneously, the solenoid control coil of another road air supply channel can not be switched on by interlocking.When just when the storage pressure of air feed is lower than set point, the normally open contact of pressure switch disconnects, the control coil outage of electromagnetically operated valve, and closed electromagnetic valve, this road air supply channel stops air feed; Simultaneously, the solenoid control coil conducting of another road air supply channel, electromagnetically operated valve is opened air feed.The utility model is simple in structure, use is reliable, easy to maintenance owing to do not shut down ventilation, therefore can guarantee that laser turns round continuously, enhance productivity and crudy.
