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, it comprises transition conducting rod and the removable electric nozzle of leading to lead the electric nozzle body, transition conducting rod one end is coupling nut, and the other end is equipped with the recess, and recessed wall is equipped with the screw thread, the connecting rod that groove phase on the conducting rod matches that is equipped with on the removable electric nozzle of leading and passes through, transition conducting rod and the removable electric nozzle of leading pass through threaded connection, and the removable electric nozzle that leads is for the extra long cone from the link to terminal convergent. The utility model discloses an excessive conducting rod, the removable electric nozzle of leading are connected through the screw thread, and the removable electric nozzle that leads changes the convenience, has practiced thrift manufacturing cost, lead electric nozzle and design into extra long cone, weld the dark groove work piece in narrow clearance, convenient to use, and difficult and work piece emergence scratch start phenomenon, the welding wire can rationally be close to the work piece again, ensures welding quality, at the cross -sectional area who guarantees to have dwindled the groove under welding quality's the circumstances, the consumption and the weld time of welding material have been reduced.
Description
Technical field
The utility model relates to a kind of ignition tip used for submerged arc welding, and particularly a kind of common submerged arc welding machine narrow gap deep groove that coordinates is with being removable taper shape lengthening 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.Ignition tip is because affecting by many-sided factors such as conduction, temperature, wear-resisting and heat radiations, and ignition tip easily damages, and causes production efficiency to reduce, production cost raising.
Utility model content
The purpose of this utility model is to provide a kind of common submerged arc welding machine special removable taper shape in the deep groove submerged-arc welding of narrow gap that coordinates and lengthens ignition tip, ignition tip good conductivity, rapid heat dissipation, has durability and repeats the features such as Long-Time Service.
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, described ignition tip body is made up of transition conducting rod and replaceable ignition tip, described transition conducting rod one end is attaching nut, the other end is provided with groove, and groove inner wall is provided with screw thread, and described replaceable ignition tip is provided with the connecting rod with the groove match on transition conducting rod, transition conducting rod and replaceable ignition tip are threaded connection, and replaceable ignition tip is the lengthening cone from link to end convergent.
Good effect of the present utility model: ignition tip body is connected by screw thread by excessive conductive bar, replaceable ignition tip, as there is damage ignition tip body front end, is also unlikely to integral replacing ignition tip body, has saved production cost; Ignition tip is designed to lengthen cone, welds narrow gap deep groove workpiece, uses more convenient, and not easily with workpiece generation scratch start phenomenon, welding wire again can reasonable close workpiece, guarantee welding quality; Reducing the cross-sectional area of groove when ensureing welding quality, decreasing consumption and the weld interval of welding material.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of transition conducting rod of the present utility model;
Fig. 3 is the schematic diagram of replaceable ignition tip of the present utility model.
In figure: 1. transition conducting rod, 2. groove, 3. replaceable ignition tip, 4. connecting rod.
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. 3, one of the present utility model narrow gap deep groove ignition tip used for submerged arc welding, comprise ignition tip body, 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, described ignition tip body is made up of transition conducting rod 1 and replaceable ignition tip 3, described transition conducting rod 1 one end is attaching nut, the other end is provided with groove 2, groove 2 inwall is provided with screw thread, described replaceable ignition tip 3 is provided with the connecting rod 4 with the groove match on transition conducting rod 1, transition conducting rod 1 and replaceable ignition tip 3 are threaded connection, replaceable ignition tip 3 is the lengthening cone from link to end convergent.
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.
