Abstract
The utility model discloses an electric conducting mechanism of an automatic submerged-arc welding machine. The electric conducting mechanism comprises an electric conducting rod, an upper-end electric conducting mouth and a lower-end electric conducting mouth, wherein the upper-end electric conducting mouth and the lower-end electric conducting mouth are installed at two ends of the electric conducting rod and are respectively in threaded connection with the electric conducting rod. In addition, the axis of an inner hole of the electric conducting rod is consistent with the axes of the upper-end electric conducting mouth and the lower-end electric conducting mouth. Inner holes of the upper-end electric conducting mouth and the lower-end electric conducting mouth are identical in diameter, and the diameter is 4.2mm. The electric conducting mechanism reduces the consumption of the electric conducting mouths while improving the electric conducting performance and decreases the replacement times of the electric conducting mouths. After improvement, the replacement times of the electric conducting mouths is reduced by 50%.
Description
Technical field
The utility model relates to the automatic submerged-arc welding machine accessory, specifically a kind of automatic submerged-arc welding machine conductive mechanism.
Background technology
For a long time, Lincoln weld is a kind of very important welding method in the pressure vessel manufacturing always, to the longitudinal joint on the GB150-1998 cylindrical tube and girth welding, usually all adopts the Lincoln weld welding by it.And in the use procedure of welding machine, ignition tip consume on the conductive mechanism is very fast, the replacing number of times is frequent, not only restricted production, also caused economic loss, analyze its reason, one, existing ignition tip upper end of using directly is connected with conducting rod, aperture, conducting rod upper end is φ 8mm, and the diameter of welding wire is φ 4mm, when welding wire through wire feeder, when passing through conducting rod behind the aligning mechanism, because the conducting rod aperture is greater than the diameter of welding wire, welding wire and conducting rod are contactless, the conduction that can't rub, generation current, the aperture of ignition tip is φ 4.2mm, therefore the ignition tip and the welding wire friction generation current that only have the lower end, play electric action, so the electric current that the lower end ignition tip itself bears is larger, scaling loss is very fast.Its two, the solder flux bucket is positioned at conducting rod top because aperture, conducting rod upper end is large, solder flux easily enters conducting rod inside, enters ignition tip and causes ignition tip to stop up along with welding wire moves down solder flux, causes the ignition tip wearing and tearing.Its three, when wire oscillation is larger, then need directly replacing ignition tip.General 10 ~ 24 hours needs of the ignition tip that now uses are changed the primary conductive mouth.
In view of this, for the problems referred to above, propose a kind of reasonable in design and effectively improve the automatic submerged-arc welding machine conductive mechanism of above-mentioned disappearance.
Summary of the invention
The purpose of this utility model is to provide the automatic submerged-arc welding machine conductive mechanism, when improving the electric installation electric conductivity, has reduced the loss of ignition tip, has reduced the replacing number of times of ignition tip, the ignition tip after the improvement, and it is changed number of times and has reduced by 50%.
In order to reach above-mentioned purpose, the utility model provides the automatic submerged-arc welding machine conductive mechanism, comprises conducting rod and is installed in upper end ignition tip and the lower end ignition tip at conducting rod two ends; Described upper end ignition tip and lower end ignition tip are with the connected mode of conducting rod respectively and are threaded; And the axis of conducting rod endoporus is consistent mutually with the axis of upper end ignition tip, lower end ignition tip.
The diameter of bore of described upper end ignition tip and lower end ignition tip is consistent, is 4.2mm.
Compared to prior art, the utility model is by adding in addition an ignition tip in the conducting rod upper end, and the aperture of ignition tip is φ 4.2mm, and solder flux can't enter conducting rod, reduces the wearing and tearing of lower end ignition tip; Simultaneously, when welding wire passes through the ignition tip of upper end, just directly contact with the ignition tip of upper end, thereby generation current has been born the part electric current, made whole electric installation electric current more stable; Add in addition an ignition tip in the conducting rod upper end, played simultaneously the alignment effect to welding wire, reduced the amplitude swing of welding wire, reduced the replacing number of times of ignition tip.The utility model is simple in structure, when improving the electric installation electric conductivity, has reduced the loss of ignition tip, has reduced the replacing number of times of ignition tip, the ignition tip after the improvement, and it is changed number of times and has reduced by 50%.
Description of drawings
Fig. 1 is automatic submerged-arc welding machine vehicle structure schematic diagram in the prior art;
Fig. 2 is the structural representation of the utility model automatic submerged-arc welding machine conductive mechanism.
Among the figure: the 1-walking mechanism; The 2-wire reel; The 3-control cabinet; The 4-governor motion; The 5-funnel; The 6-wire feeder; The 7-aligning mechanism; The 8-welding gun;
11-upper end ignition tip; The 12-conducting rod; 13-lower end ignition tip.
The specific embodiment
Relevant detailed description of the present utility model and technology contents cooperate description of drawings as follows, yet accompanying drawing only provides the usefulness of reference with explanation, and the utility model is limited.
During welding, welding wire is at first by wire feeder 6 among Fig. 1, then carry out alignment through aligning mechanism 7, after enter among Fig. 2 upper end ignition tip 11, welding wire begins conduction by forming electric current with ignition tip 11 contact frictions, in 1 accompanying drawing 2, enter lower end ignition tip 13 behind the conducting rod 12 again, welding wire and lower end ignition tip CONTACT WITH FRICTION and then produce again one part of current, welding wire directly is contacted with the welder of institute part after stretching out by lower end ignition tip 13.
In whole weld job process, avoided solder flux to stop up the ignition tip that causes and worn and torn; After ignition tip improves simultaneously, welding wire is played certain alignment effect, avoided the significantly swing of welding wire.Because upper end ignition tip 11 has been born one part of current, the electric current that lower end ignition tip 13 is born diminishes, and has reduced the wearing and tearing of lower end ignition tip and has changed number of times, has improved the electric conductivity of whole electric installation.
The above only is preferred embodiment of the present utility model, and non-in order to limit claim of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to claim of the present utility model.
