Pipe welding roller device and pipe welding method

Abstract

The invention discloses a pipe welding roller device. The pipe welding roller device comprises metal wheels, rolling bearings, a bracket and a bottom plate; the pipe welding roller device is used forachieving supporting and rolling welding effects when pipes are welded; the centers of the metal wheels are welded to the inner rings of the rolling bearings, so that free rolling of the inner rings of the metal wheels is realized; the outer rings of the rolling bearings are welded on the bracket to fix the outer rings of the metal wheels; and the bottom plate is connected with the bracket so as to ensure the stability and the integrity of the overall roller device. The device plays a very important role in improving the welding speed of the pipes with large pipe diameters, increasing the welding rolling flexibility of the pipes with the large pipe diameters, and improving the pipe welding quality. The invention also discloses a pipe welding method using the pipe welding roller device.

Description

technical field [0001] The invention belongs to the technical field of pipe processing and manufacturing, and in particular relates to a pipe welding roller device and a pipe welding method using the device. Background technique [0002] The pipe processing workshop is the processing and production workshop for all marine pipe parts in the shipyard. Due to the complexity of the ship system, not only the number and variety of pipes required for shipbuilding are huge, but also the processing technology and performance requirements of each pipe are different. The production capacity and progress of the pipe processing workshop directly affect the production progress of the entire ship. It is a difficult problem for many shipbuilding companies to meet the demand for pipes in a timely manner. [0003] Although my country has vigorously developed intelligent manufacturing in recent years, due to the discrete manufacturing industry of the shipbuilding industry, the production envi...

Problems solved by technology

[0004] 1) The welding speed of the pipe cannot be guaranteed. Since the pipe is laid flat on the ground or on the platform, after the operator has welded the horizontal welding surface, when the operator needs to rotate the pipe for welding, due to the heavy weight of the large diameter pipe, the rotation is laborious and the speed is relatively high. slow, to slow down the welding speed of the pipe;

[0005] 2) When the pipe rotates on the ground or on the platform, it needs to occupy an additional area, which is unfavorable for the site planning of the welding station;

[0006] 3) When the pipe is rotating on the ground or on the platform, the welding operator cannot fix the welding position, and needs to constantly change the welding position, which reduces the welding efficiency;

[0007] 4) The welding quality of the pipe cannot be guaranteed. Since the pipe is rotating on the ground or on the platform, the position of the pipe is constantly changing. The operator needs to constantly move the position to complete the welding of the pipe, which will affect the welding quality of the pipe
