Flange disc high-accuracy butt welding device

Abstract

The invention relates to a flange disc high-accuracy butt welding device which comprises a loading mechanism, a butt welding fixing mechanism and an unloading and loading mechanism; the left side andthe right side of a positioning supporting body of the butt welding fixing mechanism are provided and connected with the loading mechanism and the unloading and loading mechanism respectively; the loading mechanism enables a steel pipe to be loaded onto the positioning supporting body of the butt welding fixing mechanism; flanges are accurately in butt welding to the two ends of the steel pipe through the butt welding fixing mechanism; and after butt jointing is finished, transferring and loading are performed on the steel pipe after butt jointing is finished through an unloading component andthe loading component of the unloading and loading mechanism. The flange disc high-accuracy butt welding device is simple in structure, accurate in butt jointing and less in needed labor force and greatly improves the production efficiency.

Description

technical field [0001] The invention belongs to the field of pipeline processing equipment, and relates to flange plate welding technology, in particular to a flange plate high-precision butt welding device. Background technique [0002] In the production of steel pipes, some steel pipes need to add flanges at both ends, and the two flanges need to be kept relatively parallel. After adjusting the angle and position, the flanges and steel pipes can be spot welded or welded. Manual operation is used to install the flange on one end of the steel pipe first, and then install the flange on the other end of the steel pipe. The flange installed first is likely to be damaged due to the inclination of the steel pipe during the installation of the other end. The dislocation or slippage of the flange plate causes secondary correction or secondary installation, which consumes manpower. Therefore, a device that can simultaneously install the flange plates at both ends of the steel pipe i...

Problems solved by technology

[0002] In the production of steel pipes, some steel pipes need to add flanges at both ends, and the two flanges need to be kept relatively parallel. After adjusting the angle and position, the flanges and steel pipes can be spot welded or welded. Manual operation is used to install the flange on one end of the steel pipe first, and then install the flange on the other end of the steel pipe. The flange installed first is likely to be damaged due to the inclination of the steel pipe during the installation of the other end. The misalignment or slippage of the flange causes secondary correction or secondary installation, which consumes manpower. Therefore, a device that can install the flanges at both ends of the steel pipe at the same time is needed to save manpower and simplify the process.

Moreover, this affects the processing of flange welding to a certain extent, and affects people's pipeline connection operations.

Moreover, if the workers want to transport the off-line straight seam welded steel pipes to the flange welding processing site, they need to go through the process of transportation, breaking bundles, etc., and then manually operate the alignment welding for flange butt joint. The operation is dangerous, the operation is difficult, the operation is difficult, the labor intensity of the workers is high, and the production efficiency of flange butt joint is seriously affected.
