Abstract
The utility model discloses a gas flow monitoring device of a gas shielded welding machine, and belongs to the field of welding. The gas flow monitoring device of the gas shielded welding machine solves the problems that gas in a gas cylinder can not be monitored by an existing gas shielded welding machine in time, and production efficiency is reduced because welded joints lack intensive gas holes. The gas flow monitoring device comprises a welding gun and further comprises a gas supplying pipe, a tee joint, a pressure sensing switch, a first control cable and a second control cable, wherein the pressure sensing switch is communicated with the gas supplying pipe and a gas path through the tee joint, the gas supplying pipe is connected with the tee joint through a clamping hoop, the pressure sensing switch and the tee joint are connected and fastened through threads, the pressure sensing switch controls the first control cable and the second control cable to be connected or disconnected, and the first control cable and the second control cable are connected into a power supplying circuit of the welding gun. The gas flow monitoring device is used for the gas shielded welding machine.
Description
Technical field
The utility model relates to a kind of gas flow monitor of gas shielded welding machine, belongs to welding field.
Background technology
Gas shielded arc welding is a kind of welding manner of current extensive use.It is source of the gas that traditional gas shielded arc welding adopts gas cylinder; during actual welding, often because of shield gas flow rate, monitor not in time; the interior gas of gas cylinder uses up or abrupt pressure reduction makes gas flow not reach welding process requirement; make the interior atmosphere protection of welding region bad, cause weld seam to occur the problems such as porosity shortcoming.This just needs butt welded seam to do over again, and manufacturing cost is increased, and production efficiency reduces; And the weldability of part material is poor, do not allow repeatedly repair welding to reprocess, severe patient can cause product rejection.
Utility model content
The utility model object is can not monitor in time the gas in gas cylinder in order to solve existing gas shielded welding machine, and porosity shortcoming appears in weld seam, causes the problem of production efficiency reduction, and a kind of gas flow monitor of gas shielded welding machine is provided.
The gas flow monitor of gas shielded welding machine described in the utility model, it comprises welding gun, it also comprises air supply pipe, threeway, pressure-sensitive switch, the first control cable and the second control cable,
Described pressure-sensitive switch is connected with gas circuit by threeway and air supply pipe, and air supply pipe is connected by clip with threeway, and pressure-sensitive switch and threeway are threaded connection fastening,
Pressure-sensitive switch is controlled first and is controlled the break-make that cable and second is controlled cable, and the first control cable and second is controlled cable and is connected in the current supply circuit of welding gun.
Advantage of the present utility model:
1, reduced the generation of the shortcomings such as intensive pore;
2, in welding process, realize the automatic detection that gas flow changes;
3, improve weldquality, reduce rework rate, and then enhance productivity;
4, improved autgmentability, the multiple welding manner that to be applicable to take gas be protective medium;
5, simply rapid to the repacking of existing system, with low cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the gas flow monitor of gas shielded welding machine described in the utility model;
Fig. 2 is three-port structure schematic diagram described in the utility model, and wherein: a is sensor interface, b is air inlet, and c is gas outlet.
The specific embodiment
The specific embodiment one: present embodiment is described below in conjunction with Fig. 1; the gas flow monitor of gas shielded welding machine described in present embodiment; it comprises welding gun F, and it also comprises that air supply pipe C, threeway E, pressure-sensitive switch D, first control cable A and second and control cable B
Described pressure-sensitive switch D is connected with gas circuit by threeway E and air supply pipe C, and air supply pipe C is connected by clip with threeway E, and pressure-sensitive switch D and threeway E are threaded connection fastening,
Pressure-sensitive switch D controls first and controls the break-make that cable A and second controls cable B, and the first control cable A and second controls cable B and is connected in the current supply circuit of welding gun F.
In present embodiment, clip is used for guaranteeing air supply pipe C and threeway E sealing.
The specific embodiment two: below in conjunction with Fig. 2, present embodiment is described, present embodiment is described further embodiment one, the air inlet diameter of described threeway E is 8mm, gas outlet diameter is 1mm.
In present embodiment, the air inlet of threeway E and gas outlet diameter are inconsistent, for the gas pressure approximately constant that guarantees that pressure-sensitive switch D obtains.
The specific embodiment three: below in conjunction with Fig. 1, present embodiment is described, present embodiment is described further embodiment one, described threeway E and pressure-sensitive switch D are arranged on wire-feed motor G.
Operation principle: during welding, first the working range of pressure-sensitive switch D is set, when gas flow can meet technological requirement, pressure-sensitive switch D produces action under the effect of gas pressure, connect first and control cable A and the second control cable B, carry out welding operation.When gas, use up or other reasons build-up of pressure reduces while not reaching the required gas flow of welding process requirement, pressure-sensitive switch D automatic disconnection first is controlled cable A and second and is controlled cable B, stops welding.
According to the shield gas flow rate requirement in welding condition; the working range of pressure-sensitive switch (D) can preset; when in welding condition, welding protection gas traffic requirement changes, the working range of pressure-sensitive switch (D) can correspondingly be adjusted.
