Utility model content

The utility model provides a kind of supply air line for being exclusively used in gas-shielded welder, solves according to air demand size, regulation The technical problem of airway tube quantity, airway tube service life is not only extended, and damage can be changed under job state Airway tube.

In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that：

A kind of supply air line for being exclusively used in gas-shielded welder, including the air inlet terminal and and welded pipeline connected with feeder The exhaust terminal of connection, air inlet terminal are arranged on the rear board of welding machine, and exhaust terminal is arranged on the front panel of welding machine, and it is special Sign is, is connected between air inlet terminal and exhaust terminal with two airway tubes arranged side by side, two airway tubes, the air inlet terminal End forms two branch pipes, and inlet end of the two branch pipes respectively with two airway tubes connects, the head end of the exhaust terminal Form two branch pipes, exhaust end of the two branch pipes respectively with two airway tubes connect, two branch pipes of two air inlet terminals with It is vented on two branch pipes of terminal and is respectively mounted magnetic valve, for controls the on and off of branch pipe.

Compared to the prior art, beneficial effect caused by the utility model is pacified between air inlet terminal and exhaust terminal Fill two airway tubes, magnetic valve is installed on the branch pipe of air inlet terminal and exhaust terminal, the effect of magnetic valve is to control leading for branch pipe It is logical or close, when such air demand is big, two airway tubes can be opened simultaneously, two airway tubes is supplied together, works as air demand Hour, an airway tube is closed, opens another airway tube, supplies single airway tube, such as one of airway tube gas leakage needs Change, the magnetic valve at the gas leakage airway tube both ends can be closed, keep another airway tube to turn on, so do not influenceing welding work Under conditions of industry, gas leakage airway tube is changed, it follows that this programme not only extends the service life of airway tube, and is improved Operating efficiency.

The utility model also does following improvement：

Described two airway tubes are flat in approximately the same plane, and the elastic portion of support airway tube is set between two airway tubes Part, two airway tubes are made to be in elastic tension state.

The elastomeric element includes an outer barrel, two inner cylinders and two support shafts, the insertion of outer barrel both ends, the end seal of inner cylinder one Close, the other end opens wide, the blind end of two inner cylinders stretches into from the both ends of outer barrel respectively, the outer peripheral face of inner cylinder and the inner peripheral surface of outer barrel Screw thread coordinates, and when rotating outer barrel, makes two inner cylinders move toward one another or motion backwards simultaneously simultaneously, one end point of two support shafts Be not built in inner cylinder, the other end of two support shafts is supported on the airway tube of corresponding side, between support shaft and inner cylinder between Helical spring is respectively mounted in gap.

The fixed rigid annular sleeve of suit fixed respectively, the end of the support shaft for supporting airway tube on the airway tube It is fixed in annular sleeve.

Embodiment

The utility model is elaborated with reference to the accompanying drawings and examples.

As shown in figure 3, the end of air inlet terminal 3 forms Liang Ge branches, it is branch pipe 5 and branch pipe 8 respectively, is vented the He of terminal 2 Air inlet terminal 3 has approximate structure, that is, forms two branch pipes in the head end of air inlet terminal 2, is branch pipe 13 and branch respectively Pipe 14.Branch pipe 5 is connected with branch pipe 13 with airway tube 6, and branch pipe 8 is connected with branch pipe 14 with airway tube 9.Also installation is electric on four branch pipes Magnet valve, as installed magnetic valve 12 on airway tube 5, magnetic valve 11 is installed, the effect of magnetic valve is the corresponding branch of control on airway tube 8 The on and off of pipe.

Based on constituted above, when the air inflow of air inlet terminal 3 is big, while the magnetic valve on four branch pipes is opened, make to lead Tracheae 6 and airway tube 9 turn on, and the gas flow into air inlet terminal 3 shunts through two airway tubes, effectively reduces to single air guide The damage of pipe；When air inflow is small, any magnetic valve at the both ends of airway tube 6 can be closed, closes airway tube 6.Further, when One of airway tube damages gas leakage, such as airway tube 6, at this moment needs to simultaneously close off the magnetic valve at the both ends of airway tube 6, and keep leading Tracheae 9 turns on, and so in the case where not stopping welding, can change airway tube 6.

In practice, installation airway tube, the length of airway tube generally compare the distance between two branch pipes greatly for convenience, this Sample makes airway tube be in relaxed state, the connection being easy between interface.But when gas by when, loose airway tube is easy Bounce, makes airway tube easily scratch or rub.In order to solve this problem, such as Fig. 4, elasticity is installed between two airway tubes Part 7, the effect of elastomeric element 7 are two airway tubes is in tensioning state, possess good stability.As Fig. 5 is shown One embodiment of elastomeric element.Elastomeric element 7 includes an outer barrel 704, the insertion of the both ends of outer barrel 704, and two one end are closed, be another The inner cylinder of open at one end, such as inner cylinder 702 and inner cylinder 705, the blind end of inner cylinder 702 stretches into the upper end of outer barrel 704, inner cylinder 705 Blind end stretches into the lower end of outer barrel 704, the outer peripheral face screw thread cooperation of the inner peripheral surface and outer barrel of two inner cylinders, in rotation outer barrel 704 When, move toward one another or the motion backwards simultaneously simultaneously of two inner cylinders, realizing the structure of This move process can be：By inner cylinder 702 and the thread matching structure of inner cylinder 705 and outer barrel 704 be designed to reverse geometry, as the screw thread trend on outer barrel 704 is consistent, Inner cylinder 702 is opposite with the trend of inner cylinder 705.The openend of two inner cylinders is embedded in support shaft 701 and support shaft 706 respectively, support Helical spring is installed, such as helical spring 703, the other end of support shaft is fixed on the annular sleeve on airway tube between axle and inner cylinder On, annular sleeve is preferably rigid structure, plays stable support function.Such as the annular sleeve 10 installed on airway tube 6, support shaft 701 It is fixed in annular sleeve 10.
