Abstract
The invention refers to a conductive nozzle, and particularly to a submerged-arc welding eccentric conductive nozzle. The submerged-arc welding eccentric conductive nozzle is composed of a conductive bar, a conductive nozzle and a nut; the center of the conductive bar is provided with a through hole along the axial direction, and the center of the conductive nozzle is provided with a wire delivery hole along the axial direction, wherein the center lines of the through hole and the wire delivery hole are not on the same one straight line; the conductive bar and the conducive nozzle are fixedly connected through a nut. After adopting the structure, necessary contact pressure can be generated by using the bending of a welding wire before entering the conductive nozzle for the conductive nozzle and the axial line of the conductive nozzle are not on the same one concentricity, and thereby the conductive contact is guaranteed, the welding arc breaking caused by unsmooth wire delivery is avoided, and a good welding effect is guaranteed; through setting an alloy block, the submerged-arc welding eccentric conductive nozzle avoids the scraping of the welding wire on five inner walls of the wire delivery holes, prolongs the service life of conduction, and guarantees good welding effect.
Description
Technical field
The present invention relates to a kind of ignition tip, particularly a kind of submerged-arc welding centering type ignition tip.
Background technology
Ignition tip belongs to welding consumptive material, welding gun caudal end part, the metal mouth of delivery welding wire.In conventional ignition tip, the axis of conducting rod and ignition tip is on same straight line, welding wire carries out delivery by the through hole of conducting rod and ignition tip inside, and when the thin welding wire welding using diameter at below 2mm, the welding wire before entering ignition tip with certain flexibility is just easy to disalignment line, is difficult to realize the conductive contact with welding material.
Summary of the invention
For above-mentioned defect of the prior art, the invention provides a kind of submerged-arc welding centering type ignition tip, this ignition tip can guarantee that diameter is at the conductive contact of below 2mm thin welding wire when welding.
A kind of submerged-arc welding centering type ignition tip of the present invention; Be made up of conducting rod, ignition tip and nut; Conducting rod center is provided with through hole vertically, and ignition tip center is provided with wire feed hole vertically, and wherein, the center line in through hole and wire feed hole is not on same straight line, and conducting rod is fixedly connected with by nut with ignition tip.
Preferably, the port of export inwall in described ignition tip upper wire feeding hose hole is inlaid with alloy block.
Preferably, described ignition tip and conducting rod adopt wear-resisting chrome copper to make.
After adopting said structure, because the axis of ignition tip and ignition tip is not in a concentricity, bending and producing necessary contact before welding wire then can be utilized to enter ignition tip, thus ensure that conductive contact, avoid the problem of the welding current interruption that wire feed does not freely cause, ensure that good welding effect; By the setting of alloy block, avoid the scraping of welding wire to wire feed hole 5 inwall, extend the service life of conduction, ensure that good welding effect.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
In order to make those skilled in the art person understand the present invention program better, and enable above-mentioned purpose of the present invention, feature and advantage become apparent more, below in conjunction with embodiment and embodiment accompanying drawing, the present invention is further detailed explanation.
As shown in Figure 1, a kind of submerged-arc welding centering type ignition tip of the present invention; Be made up of conducting rod 1, ignition tip 2 and nut 3; Conducting rod 1 center is provided with through hole 4 vertically, and ignition tip 2 center is provided with wire feed hole 5 vertically, and wherein, the center line in through hole 4 and wire feed hole 5 is not on same straight line, and conducting rod 1 is fixedly connected with by spiral shell 3 mother with ignition tip 2.Because the axis of ignition tip and ignition tip is not in a concentricity, bending and producing necessary contact before welding wire then can be utilized to enter ignition tip, thus ensure that conductive contact, avoid the problem of the welding current interruption that wire feed does not freely cause, ensure that good welding effect.
Preferably, the port of export inwall in described ignition tip 2 upper wire feeding hose hole 5 is inlaid with alloy block 6, alloy block 6 in the present embodiment is cylindric, wire feed hole 5 internal diameter in diameter and ignition tip 2 is suitable, its effect arranged in avoiding the scraping of welding wire to wire feed hole 5 inwall, extend the service life of conduction, ensure that good welding effect.
Preferably, described ignition tip 2 and conducting rod 1 adopt wear-resisting chrome copper to make, and make this centering type ignition tip have high wearability, extend service life.
The above; be only the specific embodiment of the present invention, protection scope of the present invention is not limited thereto, and is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should define with claim is as the criterion.
