Abstract

The invention relates to a device for automatically welding a 90-degree large elbow. The device comprises a welding gun, a submerged arc welding trolley and winches and is characterized by also comprising an elbow turning rest, wherein struts are respectively arranged on the two sides of the elbow turning rest; pulleys are arranged at the tops of the struts; one sides of the two struts are respectively provided with one winch; an elbow is fixed on the elbow turning rest; the two ends of the elbow are respectively connected with the winches by virtue of steel wire ropes; one ends of the steel wire ropes are fixed on the winches and the other ends of the steel wire ropes are fixedly connected with the elbow by bypassing the pulleys; a rail is arranged on the welding line of the elbow; and the submerged arc welding trolley is put on the rail and is provided with the welding gun. The device runs stably and is high in welding efficiency; and the welding gun can be always vertical to the welding line so as to avoid reducing the welding line quality because a molten pool is affected by the gravity, thus obtaining the high-quality welding line.

Description

technical field [0001] The invention relates to a fully automatic bending pipe welding device, in particular to a 90-degree large-scale bending pipe automatic welding device, which belongs to the technical field of mechanical equipment. Background technique [0002] In the existing technology, the submerged arc automatic welding trolley has been widely used in the welding field. It can show excellent welding quality when welding straight seams. However, for bend pipes with curved arcs, only the trolley is Unable to realize automatic welding. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a fully automatic and high-efficiency automatic welding device for 90-degree large-scale pipe bends. The device operates smoothly and has high welding efficiency. [0004] According to the technical solution provided by the present invention, the 90-degree large-scale elbow automatic welding device inclu...
