Cable 51 is drawn from handle 1, and connects electric welding machine 8.The circuit connection structure of control loop is as shown in Fig. 2, setting in electric welding machine 8
There are power supply module 81 and relay 82.One end that high temperature turns off temperature detect switch (TDS) 52 passes through one end of circuit connection bat-handle switch 53,
The other end of high temperature shutdown temperature detect switch (TDS) 52 and bat-handle switch 53 is separately connected two control cables 51, one of control cable
51 are directly connected to the power supply module 81 in electric welding machine 8, another control cable 51 connects 82 control terminal of relay in electric welding machine 8
One end, the other end of 82 control terminal of relay connects power supply module 81.Power input cable 4 also connects the confession in electric welding machine 8
Electric module 81, one end of the controlled terminal of relay 82 connect power supply module 81, and the other end connects power input cable 4.Handle is opened
Closing 53 is normal open switch, and only when pressing bat-handle switch 53, bat-handle switch 53 can be just closed.It is normal that high temperature, which turns off temperature detect switch (TDS) 52,
Closed form temperature switch, and high temperature shutdown temperature detect switch (TDS) 52 has the criticality safety value set.High temperature shutdown temperature control is opened under room temperature
52 closures are closed, when pressing bat-handle switch 53, electric welding machine 8 exports low current to control cable 51, and the controlled terminal of relay 82 is connected,
Electric welding machine 8 exports high current to power input cable 4, and high temperature alarm welding gun is started to work；When temperature gradually rises to critical peace
When total head, high temperature turns off temperature detect switch (TDS) 52 and disconnects, and electric welding machine 8 stops exporting low current, the controlled terminal of relay 82 to control electricity 1
Shutdown, electric welding machine 8 stop exporting high current to power input cable 4, and high temperature alarm welding gun stops working；At this point, if temperature by
When gradually decreasing below criticality safety value, high temperature shutdown temperature detect switch (TDS) 52 is re-closed, and close handles switch 52 can make high temperature
Alarm welding gun is reworked.
In order to facilitate signal, power input cable 4 and control 51 two cables of cable are decorated in Fig. 1, it is practical in this reality
It applies in example, power input cable 4 and control cable 51 are a coaxial cable, and the center copper wire of coaxial cable is control cable
51, the annular conductive layer of coaxial cable is power input cable 4.A hollow pipe, the hollow pipe are additionally provided in coaxial cable
As wire-feeding pipe 3.
Alarm circuit includes alarm lamp 61, high temperature alarm temperature detect switch (TDS) 62, detection button switch 63, battery 64.Alarm lamp
61 and detection button switch 63 be arranged on the outer surface of handle 1, high temperature alarm temperature detect switch (TDS) 62 is tightly attached to the appearance of gooseneck 2
On face.Battery 64 can select button-type zinc-mercuric oxide cell resistant to high temperature, and battery 64 is also close to gooseneck 2 close to 1 one end of handle
On outer surface, and high temperature shutdown temperature detect switch (TDS) 52 and high temperature alarm temperature detect switch (TDS) 62 are located at the two sides of gooseneck.Alarm circuit
Circuit connection structure as shown in figure 3, high temperature alarm temperature detect switch (TDS) 62 one end connection alarm lamp 61 one end, high temperature alarm temperature
Control the anode that switch 62 connects battery 64, the cathode of the other end connection battery 64 of alarm lamp 61.Detection button switch 63 is in parallel
In high temperature alarm temperature detect switch (TDS) 62.High temperature alarm temperature detect switch (TDS) 62 is open type temperature switch, and high temperature alarm temperature detect switch (TDS) 62
With the setting safety value set, and criticality safety value is higher than setting safety value.High temperature alarm temperature detect switch (TDS) 62 is disconnected under room temperature
It opens；When temperature gradually rises to when setting safety value, high temperature alarm temperature detect switch (TDS) 62 is disconnected；At this point, if temperature is gradually decrease to
When setting safety value, high temperature alarm temperature detect switch (TDS) 62 is re-closed.Criticality safety value is higher than setting safety value.Detection button switch
63 be normal open switch, and only in Pen-down detection button switch 63, detection button switch 63 can be just closed.
The application method of high temperature alarm welding gun of the present invention is as follows:
When operator uses high temperature alarm welding gun, handle 1, and Pen-down detection button switch 63 are held, if alarm lamp 61
It does not shine, then 64 failure of alarm lamp 61 or battery, in order to ensure that operator is not burned, guarantees welding quality and protect weldering
Rifle needs to reuse welding gun after repairing alarm circuit；If alarm lamp 61 shines, alarm lamp 61 and the normal work of battery 64 are proved
Make, welding gun can be continued to use.
Operator unclamps detection button switch 63, then presses bat-handle switch 53, electric welding machine 8 begins through power input
Cable 4 is powered to gooseneck 2, forms electric arc between weldment, weldment and gooseneck 2 with the end of gooseneck 2.Electric welding machine 8 will simultaneously
Welding wire is sent by wire-feeding pipe 3 to gooseneck 2, and the head of welding wire is stretched out from the end of gooseneck 2.Electric arc heated welding wire and weldment are completed
Welding.If operator's misoperation increases the temperature of high temperature alarm welding gun constantly, and be higher than setting safety value when, high temperature
Temperature detect switch (TDS) 62 of alarming is closed, and alarm lamp 61 starts to shine, play a warning role to operator.Setting safety value can basis
Actual demand is adjusted, and is typically set at 65 DEG C.Operator's release handle switch 53 stops welding, welds high temperature alarm
The temperature of rifle gradually decreases, and when the temperature of high temperature alarm welding gun is lower than setting safety value, high temperature alarm temperature detect switch (TDS) 62 is disconnected,
Make alarm lamp stop shining, notifies operator that can continue to use welding gun.
If the warning that operator ignores alarm lamp 61 continues to weld, the temperature of high temperature alarm welding gun continues to increase, and works as height
When the temperature of temperature alarm welding gun is higher than criticality safety value, high temperature turns off temperature detect switch (TDS) 52 and disconnects, and pressure stops high temperature alarm welding gun
It only works, the temperature of high temperature alarm welding gun starts to reduce.When the temperature of high temperature alarm welding gun is lower than criticality safety value, high temperature is closed
Disconnected temperature detect switch (TDS) 52 is closed, and close handles switch 53, high temperature alarm welding gun work at this time, and operator can continue to weld
Operation.Operator can also be with overview alarm lamp 61, when alarm lamp 61 stops shining, and the temperature of high temperature alarm welding gun, which is lower than, to be set
When Dingan County's total head, the temperature of high temperature alarm welding gun is inevitably less than criticality safety value, high temperature alarm after close handles switch 53 at this time
Welding gun works on.
High temperature alarm welding gun of the present invention can be different according to the technique of welding, can choose different set safety value and critical
The temperature detect switch (TDS) of safety value, the risk for extending the service life of welding gun, reducing operator's burn, burning.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
