Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] The existing gantry submerged arc welding machine mainly includes the main machine, welding cabinet, welding torch, guide rail, open trapezoidal box 1, solder 2, solder channel 3, manual control valve 4, welding wire 5, welding wire channel 6, suction pipe 8, storage box 15 and other components. Submerged arc welding is mainly used to weld workpieces with a corner seam of 30°~120°. The guide rail in the gantry submerged arc welding machine can automatically adjust the welding accuracy (the angle of the guide rail can be selected according to the welding corner seam of the workpiece), and the straight line accuracy can always be maintained. Less than 1mm, to ensure the straight line accuracy of the weld bead. However, the existing gantry submerged arc welding machine has certain problems in the process of welding flux filling and recycling, which will ...

Abstract

The invention discloses a gantry submerged arc welding machine with automatic welding flux adjusting and drying functions, and relates to the field of gantry submerged arc welding machine equipment. The machine comprises a main machine, a welding cabinet, a welding gun, a guide rail, welding flux, a welding wire, a welding wire channel, an automatic welding flux adjusting device and an automatic welding flux drying device, the recovered welding flux is automatically filtered and dried through the welding flux automatic drying device, and the electromagnetic valve is matched with the relay to achieve automatic control over the welding flux flow. The control precision is high, operation is easy, safety and reliability are achieved, the welding process and the welding quality are improved, the welding flux recycling amount is reduced, the welding flux utilization rate is increased, the labor intensity of workers is relieved, and the working efficiency and the welding process level are improved; and a stepped filtering mode is adopted, so that the filtering effect is improved, the impurity rate of the welding flux is reduced, and welding gas and waste discharge is reduced; and moisturein the welding flux can be removed through filtering and heating, and meanwhile the welding flux is separated from impurities.

Description

technical field [0001] The invention relates to the technical field of gantry submerged arc welding equipment, in particular to a gantry submerged arc welding machine with functions of automatic adjustment and drying of flux. Background technique [0002] As we all know, gantry submerged arc is an indispensable heavy equipment in the equipment manufacturing industry. It is widely used in the welding of bridges, ships and various heavy steel structures. The welding thickness is large and the length is long. The length of the track can be extended according to the design requirements. To about 100 meters, the welding thickness of the steel plate can reach 4-80mm. It is characterized by high welding strength, less pores, small deformation and high welding efficiency. It is one of the main equipment necessary for the equipment manufacturing industry. [0003] The main consumables for submerged arc welding are welding wire and flux. Welding wires of different diameters and mater...
