The utility model discloses a kind of elbow interior wall submerged arc welding Special arm, it comprises cranks arm and connecting rod; The curvature of described crooked radian of cranking arm and curvature and elbow is suitable with radian; Connecting rod is arranged on the upper end of cranking arm, and submerged arc tip is arranged on the lower end of cranking arm; Described cranking arm detachably is arranged on welding machine telescopic arm by described connecting rod.Structure of cranking arm of the present utility model is simple, and production cost is low, and scope of application coverage rate is large, and a set of Special arm can cover two or more bore elbow welding, avoids frequent replacing and cranks arm.Welding stability is high, and product repair rate is low.Improve production efficiency, reduce production cost.
Description
Technical field
The utility model relates to a kind of elbow interior wall submerged arc welding Special arm.
Background technology
Elbow is the pipe fitting changing pipeline direction, and the material of elbow has cast iron, stainless steel, steel alloy, malleable cast iron, carbon steel, non-ferrous metal and plastics etc.; Angularly divide, have 30 °, 45 °, 60 ° and 90 ° etc. multiple.In butt-welding elbow manufacturing process, elbow interior wall longitudinal seam be welded as key operation, directly have influence on quality and the speed of production of product.The common welding of cranking arm of general employing, because common welding is cranked arm poor stability, complicated operation, and can only weld for the elbow of a kind of bore and radius of curvature.Reduce production efficiency and capacity utilization, add production cost.
Utility model content
For solving the problem, the purpose of this utility model be to provide a kind of can the elbow interior wall submerged arc welding Special arm of weld ell internal weld seams, this Special arm structure is simple, can be adapted to the elbow of multiple curvature.Only curvature is used to be the welding that 1067,1524,1,981 three kinds of Special arms can cover DN600 ~ DN1400 elbow.
For achieving the above object, a kind of elbow interior wall submerged arc welding Special arm disclosed in the utility model, it comprises cranks arm and connecting rod; Curvature and the radian of described crooked radian of cranking arm and curvature and elbow match; Connecting rod is arranged on the upper end of cranking arm, and submerged arc tip is arranged on the lower end of cranking arm; Described cranking arm detachably is arranged on welding machine telescopic arm by described connecting rod.
Further, described connecting rod is arranged on welding machine telescopic arm by snap fit or thread connecting mode.
Further, interior setting is cranked arm described in for holding the through hole of power line or conveying welding wire.
Further, described in the crooked radian of cranking arm be 70 ° ~ 90 °, curvature is 1676 ~ 2591.
Further, described connecting rod and described angle of cranking arm between the tangent line of upper end are 80-120 degree.
Further, described connecting rod length is greater than elbow diameter.
Crank arm during welding extend into corresponding bore and curvature elbow in weld.Compared with prior art, structure of cranking arm of the present utility model is simple, and production cost is low, and scope of application coverage rate is large, and a set of Special arm can cover two or more bore elbow welding, avoids frequent replacing and cranks arm.Welding stability is high, and product repair rate is low.Improve production efficiency, reduce production cost.
Accompanying drawing explanation
Fig. 1 is the structural representation welding Special arm in utility model;
Fig. 2 is the structural representation arranging through hole in Special arm.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1, a kind of elbow interior wall submerged arc welding Special arm, it comprises crank arm 2 and connecting rod 1; Crank arm 2 crooked radian suitable with radian with the curvature of curvature and elbow 4; Connecting rod 1 be vertically set on crank arm 2 upper end, submerged arc tip 5 be arranged on crank arm 2 lower end; Crank arm and 2 to be detachably arranged on welding machine telescopic arm 3 by snap fit or thread connecting mode by connecting rod 1.Connecting rod 1 length is 1.2-2 times of elbow diameter.
As shown in Figure 2, in order to carry power line or welding wire, crank arm 2 inside be provided with through hole 2a.
Below only describe several preferred embodiments of the application by reference to the accompanying drawings, but the application is not limited thereto, every those of ordinary skill in the art are under the spirit not departing from the application, and any improvement made and/or distortion, all belong to the protection domain of the application.
