Abstract
The utility model relates to a single-power supply three-wire submerged arc welding gun, which consists of three sets of electricity-conducting rods, electricity-conducting nozzles, cable clamps, welding gun clamps, insulating sleeves and wire feeding hose connectors and a welding gun supporting plate, wherein the cable clamps for a front welding gun and a back welding gun are connected with the positive electrode of a submerged arc welding power supply in parallel through cables; and the cable clamp for a middle welding gun is connected with the negative electrode of the submerged arc welding power supply through cables. With the adoption of the welding gun, the production efficiency can be improved by 30-50 percent, while the energy of welding wires is reduced by 15-30 percent and the energy can be saved by 15-30 percent.
Description
Technical field
The utility model relates to the accessory of submerged-arc welding.
Background technology
Being greatly improved of the single power supply double-wire submerged-arc welding productivity ratio single supply monofilament that occurs now, and reduced the heat input that welds; But, still existing arc welding when dc reverse connection (workpiece connects negative pole), workpiece is overheated problem of burning easily, and the energy of welding arc still is not fully utilized.
Summary of the invention
This practicality is new for using the separate unit submerged arc welding electric power; Adopt three wire bond rifles; Wherein forward and backward two rifle through cable and be connected to the positive pole of a submerged arc welding electric power; Striking welding arc between welding wire and the workpiece, and that middle welding gun is connected on the negative pole of power supply is parallelly connected with workpiece, welding wire wherein is as the filling silk of electric arc; In general welding, front and back three are the vertically arrangement welding of advancing of rifle, and three the rifle welding of advancing side by side when built-up welding, can obtain productivity ratio higher on the wideer weld seam.
Three submerged arc welding guns of single supply; A kind of submerged arc welding gun; It is characterized in that: form by three cover conducting rods (1), ignition tip (2), cable clip (3), welding gun folder (4), insulation sleeve (5), wire convey soft pipe joint (6) and a welding gun supporting plate (7); Before and after the cable clip (3) of two rifles by cable and be connected on the positive pole (+) of a submerged arc power supply, the cable clip of middle rifle (3) is gone up parallelly connected with workpiece by the negative pole (-) that cable is connected on submerged arc welding electric power; Conducting rod (1) adjustable included angle of former and later two conducting rods (1) in the middle of relatively, it is adjustable between 24～30mm to make welding wire stretch out the spacing of front and back, ignition tip 30mm place two welding wires.
The advantage of comparing and being had with background technology:
1, production efficiency raises the efficiency 30～50% than existing single power supply double-wire submerged-arc welding;
2, weld heat input lowers efficiency 15～30% than existing single power supply double-wire submerged-arc welding, especially for high strength steel, stainless steel in heat sensitive and need the little welding of weld heat input, has favorable manufacturability;
3, this energy-saving effect is than the energy-conservation effect 15～30% of existing single power supply double-wire submerged-arc welding;
4, cost performance is high, and a submerged arc welding electric power is only used three submerged arc welding guns of single supply instead and increased by two wire-feed motor, just can obtain big benefit.

The specific embodiment
Three submerged arc welding guns of single supply; A kind of submerged-arc welding welding gun; It is characterized in that: form by three cover conducting rods (1), ignition tip (2), cable clip (3), welding gun folder (4), insulation sleeve (5), wire convey soft pipe joint (6) and a welding gun supporting plate (7); The cable clip (3) of two rifles in front and back is connected in parallel on by cable on the positive pole (+) of a submerged arc power supply (8), and the cable clip of middle rifle (3) is gone up parallelly connected with workpiece by the negative pole (-) that cable is connected on submerged arc welding electric power (8); The adjustable included angle of the conducting rod (1) of former and later two conducting rods (1) in the middle of relatively, it is adjustable between 24～30mm to make welding wire stretch out the spacing of front and back, ignition tip 30mm place two welding wires.In general welding, three the welding of advancing of rifle file, and in built-up welding three the rifle welding of advancing side by side.
