Abstract
The invention discloses a welding gun cooling protection device for an argon arc welder, and relates to the technical field of argon arc welders. The welding gun cooling protection device comprises an argon arc welding gun provided with a cooling water jacket, the cooling water jacket is communicated with a cold water inlet pipe, and the argon arc welding gun is connected with the argon arc welder through a power wire. The welding gun cooling protection device is characterized in that a water pressure switch is arranged on the power wire and communicated with the cold water inlet pipe through a branch cold water pipe. A working power supply of the argon arc welding gun is cut off when cooling water pressure is insufficient, the argon arc welding gun is prevented from being damaged by fire, and the service life of the argon arc welding gun is prolonged.
Description
Technical field
The present invention relates to the argon arc welding machine technical field.
Background technology
Argon arc welding machine is in the production process of steel-plastic composite pipe streamline, it is the key equipment of welding sequence in the 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 to make the argon-arc welding gun cooling 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 the argon-arc welding gun scaling loss.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of welding gun Cooling protector of argon arc welding machine, has and disconnect the argon-arc welding gun working power when cooling water pressure is not enough, prevents the characteristics that argon-arc welding gun is burnt.
For solving the problems of the technologies described above, the technical solution used in the present invention 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 the hydraulic pressure pressure switch, and described hydraulic pressure pressure switch is connected with cold water inlet by branch's cold water pipe.
The further improvement that the present invention is done is: described power line comprises left section power line and right section 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 all are positioned at enclosure, the left end of electric contact movable contact is connected with argon arc welding machine by left section 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 power line is positioned at the right side of electric contact movable contact, the right-hand member of right section power line is connected with argon-arc welding gun.
The beneficial effect that adopts technique scheme to produce is: disconnect the argon-arc welding gun working power when cooling water pressure is not enough, prevents that argon-arc welding gun is burnt, extend the service life of argon-arc welding gun.
The accompanying drawing explanation
The welding gun Cooling protector operation principle block diagram that Fig. 1 is argon arc welding machine;
A kind of structural representation that Fig. 2 is the 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 power lines, 8 right sections 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 invention:
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, and 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 power line 7 and right section 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 all are positioned at enclosure, the left end of electric contact movable contact 11 is connected with argon arc welding machine 6 by left section 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 power line 8 is positioned at the right side of electric contact movable contact 11, the right-hand member of right section 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 power line 7 and right section power line 8 conductings, argon arc welding machine 6 outputs to argon-arc welding gun 5 by welding current, and the 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 power line 7 and right section power line 8 disconnect, and argon-arc welding gun 5 quits work.
Embodiment 2: the present embodiment and embodiment 1 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 all are positioned at enclosure, the left end of electric contact movable contact 11 is connected with argon arc welding machine 6 by left section 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 power line 7 and right section 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 power line 7 and right section power line 8 disconnect, and argon-arc welding gun 5 quits work, and prevents scaling loss.
