Argon arc welding machine is in the production process of steel-plastic composite pipe streamline, it is the key equipment of welding sequence in steel pipe forming process, its duty is operation continuously, and the cooling jacket of argon-arc welding gun must pass through circulating cooling water for cooling, the normal operation of guarantee argon-arc welding gun.In prior art, the cooling jacket of argon-arc welding gun is to carry cooling water that argon-arc welding gun is lowered the temperature by cold water pipes, and cooling water temperature is recycled.But this device can not carry out cooling protection to argon-arc welding gun when cooling water pressure is not enough, often causes argon-arc welding gun scaling loss.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of welding gun Cooling protector of argon arc welding machine, has when cooling water pressure is not enough and disconnects argon-arc welding gun working power, prevents the feature that argon-arc welding gun is burnt.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of welding gun Cooling protector of argon arc welding machine, comprise the argon-arc welding gun that is provided with cooling jacket, this cooling jacket is connected with cold water inlet, and argon-arc welding gun is connected with argon arc welding machine by power line; It is characterized in that: described power line is provided with hydraulic pressure pressure switch, described hydraulic pressure pressure switch is connected with cold water inlet by branch's cold water pipe.
The further improvement that the utility model is done is: described power line comprises left section of power line and right section of power line, the structure of described hydraulic pressure pressure switch is: comprise the electric contact movable contact in normally open, spring and shell, described electric contact movable contact and spring are all positioned at enclosure, the left end of electric contact movable contact is connected with argon arc welding machine by left section of power line, the right-hand member of electric contact movable contact contacts with the right-hand member of spring, the left end of spring is connected with the piston in branch cold water pipe right output port, the left end of right section of power line is positioned at the right side of electric contact movable contact, the right-hand member of right section of power line is connected with argon-arc welding gun.
The beneficial effect that adopts technique scheme to produce is: when cooling water pressure is not enough, disconnect argon-arc welding gun working power, prevent that argon-arc welding gun is burnt, extend the service life of argon-arc welding gun.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the welding gun Cooling protector operation principle block diagram of argon arc welding machine;
Fig. 2 is a kind of structural representation of hydraulic pressure pressure switch.
As shown in the figure: 1 cold water source, 2 branch's cold water pipes, 3 cold water inlets, 4 hydraulic pressure pressure switches, 5 argon-arc welding guns, 6 argon arc welding machines, 7 left sections of power lines, 8 right sections of power lines, 9 pistons, 10 springs, 11 electric contact movable contacts.
The specific embodiment
Contrast Fig. 1-2 is used step to be described further to operation of the present utility model:
Embodiment 1: a kind of welding gun Cooling protector of argon arc welding machine, comprise the argon-arc welding gun 5 that is provided with cooling jacket, and this cooling jacket is connected with cold water inlet 3, and argon-arc welding gun 5 is connected with argon arc welding machine 6 by power line; It is characterized in that: described power line is provided with hydraulic pressure pressure switch 4, described hydraulic pressure pressure switch 4 is connected with cold water inlet 3 by branch's cold water pipe 2.Described power line comprises left section of power line 7 and right section of power line 8, the structure of described hydraulic pressure pressure switch 4 is: comprise the electric contact movable contact 11 in normally open, spring 10 and shell, described electric contact movable contact 11 and spring 10 are all positioned at enclosure, the left end of electric contact movable contact 11 is connected with argon arc welding machine 6 by left section of power line 7, the right-hand member of electric contact movable contact 11 contacts with the right-hand member of spring 10, the left end of spring 10 is connected with the piston 9 in branch cold water pipe 2 right output port, the left end of right section of power line 8 is positioned at the right side of electric contact movable contact 11, the right-hand member of right section of power line 8 is connected with argon-arc welding gun 5.
Using method: before starting argon arc welding machine 6, must guarantee that the pressure of cold water source 1 enough reduces the temperature of argon-arc welding gun 5, now the 9 promotion springs 10 of the piston in branch's cold water pipe 2 right output port move to right, the right-hand member of spring 10 is depressed electric contact movable contact 11 to make left section of power line 7 and right section of power line 8 conductings, argon arc welding machine 6 outputs to argon-arc welding gun 5 by welding current, and steel-plastic composite pipe streamline is produced continuously.Once the insufficient pressure of cold water source 1, now the piston in branch's cold water pipe 2 right output port 9 is retracted and is pulled spring 5 to move to left, and electric contact movable contact 11 right-hand members lift, and left section of power line 7 and right section of power line 8 disconnect, and argon-arc welding gun 5 quits work.
Embodiment 2: the present embodiment and embodiment are not both: the structure of hydraulic pressure pressure switch 4 is: comprise electric contact movable contact 11, bellows and shell in normally open, described electric contact movable contact 11 and bellows are all positioned at enclosure, the left end of electric contact movable contact 11 is connected with argon arc welding machine 6 by left section of power line 7, the right-hand member of electric contact movable contact 11 contacts with the outer end head of bellows, and the water inlet of bellows is connected with branch cold water pipe 2 right output port.Cold water source 1 pressure is when enough, and the outer end head of bellows expands electric contact movable contact 11 is depressed and made left section of power line 7 and right section of power line 8 conductings, argon-arc welding gun 5 normal operations.During cold water source 1 insufficient pressure, bellows shrinks electric contact movable contact 11 is lifted, and left section of power line 7 and right section of power line 8 disconnect, and argon-arc welding gun 5 quits work, and prevents scaling loss.
