Abstract
The utility model discloses a dark groove submerged arc welding in narrow clearance is with leading electric nozzle, including leading the electric nozzle body, lead the electric nozzle body and constitute by linkage segment and active section, the linkage segment has a coupling nut, fix on submerged arc welding equipment through coupling nut, the welding wire by welding equipment control through leading the central excessive hole of welding wire of electric nozzle body, expert's welding wire hole, lead the electric nozzle terminal surface, the active section of leading the electric nozzle body welds the dark groove work piece in narrow clearance for the extension flat, and it is more convenient to use, it extends, and the electric nozzle volume is led to flat and heat radiating area is big, and the heat dissipation is fast, is applicable to the welding of long continuous time, again because the flat to lead the electric nozzle terminal surface long -pending big, so that electric nozzle resistance is led to the flat is little, electric conductivity is good, has the durability, and difficultly takes place the scratch start phenomenon with the work piece, the welding wire can rationally be close to the work piece again, guarantees welding quality, has dwindled the cross -sectional area of groove under assurance welding quality's the circumstances, has reduced the consumption and the weld time of welding material, has practiced thrift manufacturing cost.
Description
Technical field
The utility model relates to a kind of ignition tip used for submerged arc welding, and particularly a kind of lengthening coordinates common submerged arc welding machine narrow gap deep groove flat ignition tip.
Background technology
Existing common circular conductive mouth used for submerged arc welding, because ignition tip diameter is comparatively large, in welding process, welding wire is difficult to sidewall close.Ignition tip more easily produces scratch start phenomenon the closer to mother metal, and ignition tip is damaged; Welding wire is not near sidewall again, then weld seam easily produces sidewall and do not fuse defect, and welding quality is difficult to ensure.Qualification rate as weld seam supersonic detection can not reach 100%, needs butt welded seam defect to do over again, greatly affects production efficiency.So existing common circular conductive mouth used for submerged arc welding is difficult to the welding meeting heavy thickness Narrow sloping-glot.
Utility model content
The purpose of this utility model is to provide a kind of lengthening and coordinates the special ignition tip of common submerged arc welding machine in the deep groove submerged-arc welding of narrow gap.
The purpose of this utility model is achieved through the following channels:
A kind of narrow gap deep groove ignition tip used for submerged arc welding, comprise ignition tip body, ignition tip body is made up of linkage section and active section, linkage section has attaching nut, be fixed on submerged arc welding device by attaching nut, welding wire is controlled through the excessive hole of ignition tip body central welding wire by welding equipment, logical welding wire hole, and derive ignition tip end face, the active section of described ignition tip body is Lengthened flat.
Further, the cross section of described ignition tip body active section becomes cydariform.
Good effect of the present utility model: ignition tip active section is designed to flat and lengthens, and welds narrow gap deep groove workpiece, uses more convenient; Greatly, rapid heat dissipation, is applicable to long-time continuous welding for its Lengthened flat ignition tip volume and area of dissipation; Again because flat ignition tip end area is large, so flat ignition tip resistance is little, good conductivity, has durability; Because ignition tip is flat, not easily with workpiece generation scratch start phenomenon, welding wire rationally near workpiece, can guarantee welding quality again; Reducing the cross-sectional area of groove when ensureing welding quality, decreasing consumption and the weld interval of welding material, having saved production cost.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to schematic diagram;
Fig. 3 is that the B-B of Fig. 1 is to schematic diagram;
Fig. 4 is that the C-C of Fig. 1 is to schematic diagram.
In figure: 1. linkage section, 2. active section, 3. welding wire transitional pore, 4. logical welding wire hole, 5. ignition tip end face.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Fig. 1-Fig. 4, narrow gap deep groove of the present utility model ignition tip used for submerged arc welding, comprise ignition tip body, ignition tip body is made up of linkage section 1 and active section 2, ignition tip body has attaching nut, be fixed on submerged arc welding device by attaching nut, welding wire is controlled through the excessive hole 3 of ignition tip body central welding wire by welding equipment, logical welding wire hole 4, derive ignition tip end face, carrying out smoothly in order to ensure welding process, weld up-to-standard weld seam, consider the electric conductivity of ignition tip, tolerable temperature and heat radiation, wear-resisting, many-sided factor such as durable, ignition tip material adopts wear-resisting and that electric conductivity is good chromium zirconium copper, the active section 2 of ignition tip body is designed to Lengthened flat, the cross section of ignition tip body active section becomes cydariform, weld narrow gap deep groove workpiece, use more convenient.
Above embodiment is only the utility model product preferably embodiment, not limits the scope of application of the utility model product with this, therefore everyly on the utility model principle of products, makes equivalence change and all should be included in protection domain of the present utility model.
Claims (2)
