Abstract
Provided is a dual-power three-wire gas shield welding gun. Three gas shield welding gun conducting rod assemblies and a current contact nozzle are combined on an insulated gun body. A front conducting rod assembly and a rear conducting rod assembly are respectively connected on anodes of two welding power supplies, a middle conducting rod assembly is connected with a workpiece, a welding wire serves as a filling wire, high welding efficiency is maintained, energy is saved by one third, and linear energy is reduced by one third.
Description
Technical field
The utility model belongs to a kind of high efficiency accessory of gas metal-arc welding.
Background technology
Problems such as occurred the gas protective welding gun of three of three power supplys abroad, production efficiency is to increase substantially, and to be shaped also more satisfactory, but when also not breaking away from the direct current reversed polarity, and heat is superfluous, overheated on the negative pole workpiece.
Summary of the invention
The technical scheme of the utility model is on dual power supply mariages gas protective welding gun basis, in the middle of rush-harvesting and rush-planting, to insert the 3rd silk filling rifle that does not connect power supply, fills a heat melts that makes full use of surplus on the negative pole workpiece and fills weld seam.Three gas protective welding guns of dual power supply; Adopt three conducting rod assemblies of two power supplys to synthesize welding gun insulated from each other; Front and back two cover conducting rod assemblies connect the source of welding current respectively; The electric arc that ignites between its welding wire and the workpiece welds, and middle conducting rod assembly links to each other with workpiece, and its welding wire act as the filling metal.
The advantage that the utility model and background technology are compared and had:
1, only with two cover power supplys, than the cover power supply of having economized of three power supplys, investment reduces by 1/3rd;
2, can be to the same productivity ratio of three power supplys, three wire bonds;
3, energy-conservation 1/3rd, the heat input of welding reduces by 1/3rd, reduces welding deformation, has favorable manufacturability for heat sensitive stainless steel, aluminium alloy and middle high strength especially.
Description of drawings
Figure, three gas protective welding guns of dual power supply
Among the figure: the source of welding current one (S1), power supply two (S2), wire-feed motor (1), conducting rod assembly (2), ignition tip (3), insulation rifle body (4), protection gas cap (5), workpiece (G).
The specific embodiment
Three gas protective welding guns of the utility model dual power supply; It is characterized in that: be combined on the insulation rifle body (4) by three cover conducting rod assemblies (2), ignition tip (3); A protection gas cap (5) is arranged outward, and front and back two cover conducting rod assemblies (2) are connected on respectively on the positive pole (+) of the source of welding current one (S1) and power supply two (S2), and middle conducting rod assembly (2) connects with workpiece (G); Be connected on simultaneously on the negative pole (-) of power supply one (S1) and power supply two (S2), formed three gas protective welding guns of dual power supply thus.Three cover wire-feed motor (1) are respectively to three cover conducting rod assembly (2) wire feeds, and three cover conducting rod assembly (2) files are welded when generally welding, and when built-up welding, the welding side by side of three cover conducting rod assemblies (2).
Claims (1)
1. three gas protective welding guns of the utility model dual power supply; It is characterized in that: be combined on the insulation rifle body (4) by three cover conducting rod assemblies (2), ignition tip (3); A protection gas cap (5) is arranged outward, and front and back two cover conducting rod assemblies (2) are connected on respectively on the positive pole (+) of the source of welding current one (S1) and power supply two (S2), and middle conducting rod assembly (2) connects with workpiece (G); Be connected on simultaneously on the negative pole (-) of power supply one (S1) and power supply two (S2), formed three gas protective welding guns of dual power supply thus.
