Welding forming machine for bent pipe and flange connection

Abstract

The invention relates to the technical field of pipeline welding, in particular to a welding forming machine for bent pipe and flange connection. The welding forming machine comprises a bottom plate, a clamping unit and a welding unit. The clamping unit is installed at the upper end of the bottom plate, and the welding unit is arranged on the clamping unit. The welding forming machine has the following problems that an existing clamp cannot adjust the angle between a bent pipe and flanges according to welding requirements, consequently, welding deviation is prone to being generated, circumferential welding cannot be realized when a worker welds the flanges and the bent pipe, the welding efficiency of the flanges and the bent pipe is influenced, and certain potential safety hazards exist when the worker carries out welding. By means of the welding forming machine, the angle between rotating plates and the bent pipe can be adjusted, the bent pipe and the flanges can be aligned conveniently, and therefore deviation generated when the bent pipe and the flanges are welded can be reduced; and by means of the welding forming machine, circumferential welding treatment can be carried out on the butt joint positions of the bent pipe and the flanges, the welding efficiency can be improved, and potential safety hazards existing during manual welding can be avoided.

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
