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

A gantry submerged arc welding machine with functions of automatic flux adjustment and drying, relating to the field of gantry submerged arc welding equipment, including a host, a welding cabinet, a welding torch, guide rails, solder, welding wire, a welding wire channel, an automatic flux adjustment device and The flux automatic drying device automatically adjusts the amount of flux through the flux automatic adjustment device, and automatically filters and dries the recovered flux through the flux automatic drying device. The electromagnetic valve and relay are used to automatically control the flux flow, with high control precision, simple operation, safety and reliability, which improves the welding process and welding quality, reduces the amount of recycled flux, improves the utilization rate of flux, and reduces the labor intensity of personnel. , Improve work efficiency and welding process level. The stepped filter method is adopted to improve the filter effect, reduce the impurity rate of welding flux, and reduce the emission of welding gas and waste. The use of filtration and heating can remove the moisture in the flux, and at the same time separate the flux 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...
