Description
Technical field
The present invention relates to 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 steel pipe forming process, its duty is run continuously, and the cooling jacket of argon-arc welding gun must pass through circulating cooling water for cooling, the normal work of guarantee argon-arc welding gun.In prior art, the cooling jacket of argon-arc welding gun by cold water pipes conveying cooling water, argon-arc welding gun is lowered the temperature, 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.
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 disconnects argon-arc welding gun working power when cooling water pressure is not enough, prevent the feature 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 being 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, 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, 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 being in normally open, bellows and shell, described electric contact movable contact and described bellows are all positioned at enclosure, the left end of described electric contact movable contact is connected with described argon arc welding machine by described left section of power line, the right-hand member of described electric contact movable contact contacts with the outer end head of described bellows, the water inlet of described bellows is connected with described branch cold water pipe right output port, when described cold water source pressure is enough, described electric contact movable contact pressure is made described left section of power line and right section of power line conducting by the outer end head expansion of described bellows, during described cold water source insufficient pressure, described bellows shrinks and described electric contact movable contact is lifted, and described left section of power line and right section of power line disconnect.
The beneficial effect adopting technique scheme to produce is: disconnect argon-arc welding gun working power when cooling water pressure is not enough, prevent argon-arc welding gun to be burnt, extend the service life of argon-arc welding gun.
Accompanying drawing explanation
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.
Detailed description of the invention
Contrast Fig. 1-2 uses 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 being provided with cooling jacket, 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 being 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 ensure that the pressure of cold water source 1 enough reduces the temperature of argon-arc welding gun 5, piston 9 now in branch's cold water pipe 2 right output port promotes spring 10 and moves to right, electric contact movable contact 11 pressure is made left section of power line 7 and the conducting of right section of power line 8 by the right-hand member of spring 10, welding current is outputted to argon-arc welding gun 5 by argon arc welding machine 6, steel-plastic composite pipe streamline continuous seepage.Once the insufficient pressure of cold water source 1, the piston 9 now in branch's cold water pipe 2 right output port is retracted and is pulled spring 5 to move to left, and electric contact movable contact 11 right-hand member lifts, 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: not being both of the present embodiment and embodiment 1: the structure of hydraulic pressure pressure switch 4 is: comprise the electric contact movable contact 11, bellows and the shell that are 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.When cold water source 1 pressure is enough, electric contact movable contact 11 pressure is made left section of power line 7 and the conducting of right section of power line 8 by the outer end head expansion of bellows, and argon-arc welding gun 5 normally works.During cold water source 1 insufficient pressure, bellows shrinks and 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.
