A bridge steel automatic welding machine

Abstract

The invention provides an automatic welding machine for bridge steel, which includes a sliding track, a drying gun, a heating tank and a heating sheet, each side wall of the gas shielded welding machine is provided with a sliding track, and each sliding track faces the traveling direction of the door frame There is a drying gun at one end of the machine, the heating groove is set on the inner side of the frame of the hydraulic swing tire frame, and the heating sheet is arranged in the heating groove, so that the position of the workpiece heated by the drying gun can be adjusted as the drying gun slides on the sliding track, not only You can use the drying gun to remove the water vapor on the surface of the workpiece, and you can also adjust the temperature of the preheated workpiece when it reaches the welding torch, so that the temperature of the workpiece during welding is an ideal temperature, and after the welding is completed, the heating sheet will also heat the workpiece. It achieves the effect of heat preservation, which is beneficial to the formation of weld seams during the welding process of the plates, and can meet the requirements of the welding process and has good practicability.

Description

technical field [0001] The invention relates to the technical field of bridge steel structure steel box girder plate unit manufacturing and welding, in particular to an automatic welding machine for seam welding of bridge steel structure steel box girder plate unit elements. Background technique [0002] At present, bridge steel structure manufacturers mostly use general-purpose gantry-type multi-head welding machines for the U-shaped rib welding of steel box girder plate units. The existence of water vapor leads to poor weld formation during the welding process of the plates, which cannot meet the requirements of the welding process. However, preheating and dehumidification of the U-shaped ribs of the steel box girder plate units that need to be welded alone not only reduces the production efficiency, but also completes the preheating at the same time. During the welding process, the temperature state of the plate is uncontrollable, and the quality of the weldment produced ...
