An elbow joint flange welding forming machine

Abstract

The invention relates to the technical field of pipeline welding, in particular to a flange welding and forming machine for elbow connection, comprising a base plate, a clamping unit and a welding unit, the clamping unit is installed on the top of the base plate, and the welding unit is arranged on the clamping unit; The present invention has the following problems: the existing fixture cannot adjust the angle between the elbow and the flange according to the welding requirements, so that welding deviation is easy to occur, and when the workers weld the flange and the elbow, they cannot achieve circumferential welding, thus affecting the The welding efficiency of the flange and the elbow is improved, and there are certain safety hazards when workers weld; the invention can adjust the angle between the rotating plate and the elbow, which is convenient for aligning the elbow and the flange, thereby reducing the Deviation during welding of the elbow and the flange; the invention can perform circumferential welding on the butt joint of the elbow and the flange, can improve welding efficiency, and can avoid potential safety hazards during manual welding.

Description

technical field [0001] The invention relates to the technical field of pipe welding, in particular to a welding and forming machine for connecting flanges of elbows. Background technique [0002] Pipes are parts used to transport gas, liquid or fluid with solid particles. Pipes are divided into straight pipes and curved pipes. The curved pipes are mainly used for the connection at the corners of the pipes. Generally, in order to facilitate the installation of the pipes, there will be Welded flanges at both ends such as Figure 9 shown, and it is convenient for the later disassembly and maintenance of the pipeline. [0003] However, there are currently the following problems in welding elbows and flanges: 1. In order to save costs, some small enterprises usually weld elbows and flanges manually. The pipe and the flange are fixed, and the existing fixture cannot adjust the angle between the elbow and the flange according to the welding requirements, which is prone to welding ...

AI Technical Summary

Problems solved by technology

[0003] However, there are currently the following problems in welding elbows and flanges: 1. In order to save costs, some small enterprises usually weld elbows and flanges manually. The pipe and the flange are fixed, and the existing fixture cannot adjust the angle between the elbow and the flange according to the welding requirements, which is prone to welding deviation and affects the welding effect

[0004] 2. Since the connection between the flange and the elbow needs to be welded in a circle, and when the workers weld the flange and the elbow, they need to rotate the flange and the elbow in turn, and the circumferential welding cannot be realized, so it affects the flange and the elbow. The welding efficiency of the elbow is high, and there are certain safety hazards when workers weld
