In the utility model, the operation principle of the straight buffers of servo wire feeder is：
In welding process, servo wire feeding motor above according to the instruction of control system with the frequency of 70 times/second forward and
Wire feed backward；Wire feeding motor below by the digital source of welding current according to system requirements according to constant wire feed rate wire feed forward,
Two wire feed systems all realize Digital Control.Laser displacement sensor is fixed in straight buffers housing, light-reflecting sheet
It is fixed on wire feed flexible pipe, laser displacement sensor is fixed on behind light-reflecting sheet, light-reflecting sheet and laser displacement sensor hair
Penetrate between face and keep fixed distance, and light-reflecting sheet and the laser displacement sensor surface of emission want keeping parallelism.
The laser that laser displacement sensor is sent is radiated on light-reflecting sheet and reflected, and passes through the transmitting of laser beam
The distance between laser displacement sensor and light-reflecting sheet are measured with receiving, if institute's ranging is set in advance from control system
Fixed distance, laser displacement sensor will provide analog signalses to control system.
In welding process, when former and later two wire feeding motor wires feed rate are equal, the light on wire feed flexible pipe is anti-
Penetrating piece will not act (being now normal weld).When the wire feed rate of above wire feeding motor is too fast relative to wire feeding motor below
When (also cry and rush silk or short circuit, short-circuit process is：Welding wire end is fused into molten drop, and molten drop forms short circuit with molten bath, when welding wire is quick-fried disconnected
With big electric current and splashing and produce substantial amounts of heat), now the free end of wire feed flexible pipe will be pulled along by welding wire, and light is anti-
Penetrating piece will move forward, and the increasing of the distance between laser displacement sensor and light-reflecting sheet, now laser displacement sensor is by mould
Intend signal and be transmitted to control system, after control system is connected to instruction, by the voltage of output, current control close to zero, and feed back to
Servo wire feeding motor above, it is desirable to its halt wire feed and make pumpback welding wire action, electric arc itself input heat mistake
Journey just makes welding wire and molten drop quick separating in short-term very much.
Under the control of totally digitilized closed loop, this transient mode is different from traditional droplet transfer mode completely.
In conventional welding process, when dry extension of electrode changes, the size of welding current can constantly change.And there is servo wire feed dress
The straight buffers put, dry extension of electrode only change wire feed rate when changing, will not cause the change of electric current, it is achieved thereby that
Consistent fusion penetration, plus the highly stable property of arc length, highly uniform weld appearance shaping can be reached.
Finally it should be noted that listed above is only specific embodiment of the utility model.Obviously, this practicality is new
Type is not limited to above example, can also there is many variations.One of ordinary skill in the art can be from disclosed in the utility model
All deformations for directly exporting or associating in content, are considered as the scope of protection of the utility model.
