Abstract
The invention discloses a current contact nozzle for a submerged arc welding machine. The nozzle comprises a first-stage contact rod, a second-stage contact rod and a conical contact nozzle, wherein one end, which is matched with the second-stage contact rod, of the first-stage contact rod is provided with a first-stage threaded hole; one end, which is matched with the first-stage contact rod, of the second-stage contact rod is provided with a first-stage threaded section; one end, which is matched with the conical contact nozzle, of the second-stage contact rod is provided with a second-stage threaded hole; and one end, which is matched with the second-stage contact rod, of the conical contact nozzle is provided with a second-stage threaded section. The current contact nozzle has the advantages that: the current contact nozzle for the submerged arc welding machine has a three-stage assembled structure so that replacement and detachment are convenient and use cost is saved; the contact nozzle has a slender structure and the second contact rod is relatively thin so that requirements on narrow clearance and the production of small welding wire can be met; and the surface of the first-stage contact rod is provided with a ceramic-sprayed coating so that a striking phenomenon does not occur even through the contact nozzle is contacted with a workpiece groove, use is safer and more reliable and welding quality is not affected.
Description
Technical field
The present invention relates to a kind of submerged arc welding machine that is used for industry collection casees such as boiler, pressure vessel, oil, chemical industry, nuclear power, pipeline submerged-arc welding welding, relate in particular to a kind of current contact nozzle for submerged arc welding machine.
Background technology
The existing ignition tip that is used for the submerged arc welding machine of industry collection casees such as boiler, pressure vessel, oil, chemical industry, nuclear power, pipeline submerged-arc welding welding comprises: contact rod and the ignition tip that is arranged on the contact rod end.Existing ignition tip is the secondary integral structure, if the ignition tip infringement just needs to change together, use cost is higher, contact rod cross thick and also ignition tip too short and small, at the outside naked facility of contact rod, in collection case, pipeline narrow gap welding termination process, be easy to bump with its groove, produce the electricity sparking, workpiece grooves and ignition tip are damaged, welding is interrupted, influence welding quality.
Summary of the invention
Technical problem to be solved by this invention provides a kind of convenient, safe current contact nozzle for submerged arc welding machine that uses.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: current contact nozzle for submerged arc welding machine, comprise: one-level contact rod, secondary contact rod and taper ignition tip, the end that one-level contact rod and secondary contact rod cooperatively interact is provided with the one-level screwed hole, the end that secondary contact rod and one-level contact rod cooperatively interact is provided with the one-level thread segment, the end that secondary contact rod and taper ignition tip cooperatively interact is provided with the secondary screwed hole, and the end that taper ignition tip and secondary contact rod cooperatively interact is provided with the secondary thread segment.
Advantage of the present invention is: above-mentioned current contact nozzle for submerged arc welding machine is three grades of modular constructions, change convenient disassembly, save use cost, ignition tip is a slim-lined construction, and the secondary contact rod is thinner, can adapt to the demand that narrow gap and little welding wire are produced, the surface of one-level contact rod is provided with the sprayed ceramic coating, can not produce spark phenomenon even make ignition tip and workpiece grooves contact yet, use safelyr, reliable, and influence welding quality.
Description of drawings
The present invention is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of current contact nozzle for submerged arc welding machine of the present invention.
Fig. 2 is the blast structural representation of current contact nozzle for submerged arc welding machine of the present invention.
Among the figure: 1, one-level contact rod, 2, the secondary contact rod, 3, the taper ignition tip, 4, the one-level screwed hole, 5, the one-level thread segment, 6, the secondary screwed hole, 7, the secondary thread segment.
The specific embodiment
As shown in Figure 1, current contact nozzle for submerged arc welding machine, comprise: one-level contact rod 1, secondary contact rod 2 and taper ignition tip 3, one-level contact rod 1 is provided with one-level screwed hole 4 with the end that secondary contact rod 2 cooperatively interacts, secondary contact rod 2 is provided with one-level thread segment 5 with the end that one-level contact rod 1 cooperatively interacts, secondary contact rod 2 is provided with secondary screwed hole 6 with the end that taper ignition tip 3 cooperatively interacts, and taper ignition tip 3 is provided with secondary thread segment 7 with the end that secondary contact rod 2 cooperatively interacts.
Above-mentioned current contact nozzle for submerged arc welding machine is three grades of modular constructions, change convenient disassembly, save use cost, ignition tip is elongated pyramidal structure, and secondary contact rod 2 is thinner, can adapt to the demand that narrow gap and little welding wire are produced, the surface of one-level contact rod 1 is provided with the sprayed ceramic coating, can not produce spark phenomenon even make ignition tip and workpiece grooves contact yet, use safelyr, reliable, and influence welding quality.
The foregoing description is only for the usefulness that the present invention is described; and be not to be limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the spirit and scope of the present invention; can also make various variations and modification, so all technical schemes that are equal to also should belong to protection category of the present invention.
