Automatic inner cylindrical circular seam welding machine with flexible rail

Abstract

The invention discloses an automatic inner cylindrical circular seam welding machine with a flexible rail. The automatic inner cylindrical circular seam welding machine comprises a main welder body, a gas supply mechanism, a cooling mechanism, and a rolling mechanism; the main welder body comprises a weld gun, wherein the weld gun is connected with a wire feeder, and the bottom part of the wire feeder is provided with a welding oscillator; the gas supply mechanism comprises a welding power source connected with the main welder body; the rolling mechanism comprises a speed regulating roller frame, and the cylinder body is located on the speed regulating roller frame; a flexible rail is arranged around the annular seam in the cylinder body, and the flexible rail comprises a rail base layer, and a rail located in the center of the rail base layer; the rail is convexly arranged on the surface of the rail base layer, both sides of the rail are respectively provided with a line of holes, and two lines of holes are aligned at intervals. The automatic inner cylindrical circular seam welding machine is added with a walking trolley, the welding oscillator and a water cold weld gun, and paves rail in the cylinder body, thus the full automatic welding of the circular seam in a pressure container is realized; the automatic inner cylindrical circular seam welding machine can apply welding to multiple circular seams at the same time, and also can eliminate the adverse influence of axial movement of the cylinder in rotating process on welding.

Description

technical field [0001] The invention relates to the technical field of automatic welding machines, in particular to an automatic welding machine for circular seam inside a cylinder with a flexible track. Background technique [0002] In recent years, with the continuous expansion of the market share of petrochemical, coal mine, non-ferrous mineral and other supporting equipment, the existing production capacity, production equipment and process management procedures of pressure vessels can no longer meet the needs of market product manufacturing. In order to meet the fierce market competition, the production capacity of pressure vessel products urgently needs to be improved, which requires more high-end equipment functions in order to achieve rapid and sustainable development. [0003] At present, the more advanced method of welding the circular seam inside the cylinder is to use a cantilever type CO2 gas shielded welding manipulator for welding, but its cantilever telescopi...

Problems solved by technology

[0003] At present, the more advanced method of welding the circular seam inside the cylinder is to use a cantilever type CO2 gas shielded welding manipulator for welding, but the cantilever telescopic length is limited, and it is powerless for super long cylinders. Some large diameter cylinders are equipped with rice-shaped supports for better Unusable and only one inner ring seam can be welded
