Weld joint guide roller for longitudinal welded pipe production line

Abstract

The welding seam guide roller comprises a bottom plate, a mounting base and a guide roller body, a first servo motor is fixedly connected to the bottom plate, a transmission shaft is fixedly connected to the output end of the first servo motor, and a rotating disc is fixedly connected to the end, away from the bottom plate, of the transmission shaft; an auxiliary supporting device is arranged between the bottom plate and the rotating disc, and a plurality of taking and placing devices are symmetrically and fixedly connected to the rotating disc. The device is easy to operate and convenient to use, guide rollers of different sizes and models can be replaced at any time according to the machining requirement of the longitudinal welded pipe, compared with traditional longitudinal welded pipe machining, it is not needed to independently arrange a machining assembly line for the guide rollers of different sizes and models, and therefore a large amount of cost and productivity waste can be saved, and the production efficiency is improved. Meanwhile, a large amount of space can be saved.

Description

technical field [0001] The invention relates to the technical field of straight seam welded pipes, in particular to a welding seam guide roller for a straight seam welded pipe production line. Background technique [0002] The straight seam welded pipe is a pipe obtained by straight seam welding of a steel pipe made of hot-rolled or cold-rolled steel plate or steel strip coil welding on a welding equipment. In the production of straight seam welded pipes, the methods to control the position of the weld seam mainly include the forming roll method, the guide roll method and the sizing roll dislocation method. The guide roller method refers to the control of the position of the welding seam in the sizing section by changing the position of the guide roller pass and the rolling center line. [0003] During the production and processing of the existing straight seam welded pipe production line, since the guide rollers of different sizes and models have different effects on the p...

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: when the existing straight seam welded pipe production line is producing and processing, the guide rollers of different sizes and models have different effects on the processing of straight seam welded pipes with different wall thicknesses and different sizes. Different functions, therefore, in order to meet the processing needs of longitudinal welded pipes of different sizes and models, usually multiple production lines are set up according to different guide rollers. Since each production line is not in use at the same time, the cost is very high and There is a lot of waste in capacity and it takes up a lot of space
