Metal pipe welding frame

Abstract

The invention belongs to the technical field of welding devices, and particularly relates to a metal pipe welding frame. The metal pipe welding frame comprises a mounting frame, a mounting seat, a sliding plate, rotating wheels and fixing mechanisms. the right end of the mounting frame is fixedly connected with the mounting seat, and the upper surface of the left end of the mounting frame is slidably connected with the sliding plate; the sliding plate can be fixed to the upper surface of the mounting frame through bolts, and the rotating wheel is rotationally mounted on the upper surface of the sliding plate. the rotating wheel is rotationally mounted on the upper surface of the mounting seat, and the rotating wheel on the mounting seat is consistent with the rotating wheel on the sliding plate; the two rotating wheels are arranged to be in a linkage state, and the fixing mechanisms are arranged outside the rotating wheels; and when the rotating wheels rotate, the outer surface of a pipe is in continuous contact with supporting plates in the outer walls of mounting rings, and a lap joint effect is achieved on the pipe through protruding parts of the supporting plates, so that the pipe cannot rotate reversely in the welding process, and meanwhile the situation that the pipe is clamped between the two rotating wheels and is difficult to rotate reversely is avoided.

Description

technical field [0001] The invention belongs to the technical field of welding devices, in particular to a metal pipe welding frame. Background technique [0002] Welding, also known as welding, is a manufacturing process and technique that uses heat, high temperature, or pressure to join metal or other thermoplastic materials such as plastics. There are many sources of energy for modern welding, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. In addition to its use in factories, welding can also be performed in a variety of environments, such as in the field, underwater and in space. Welding, wherever it occurs, can pose a hazard to the operator, so proper precautions must be taken when welding. Possible injuries caused by welding to the human body include burns, electric shock, visual impairment, inhalation of toxic gases, and excessive ultraviolet radiation.

AI Technical Summary

Problems solved by technology

[0003] The welding operation in the prior art is generally done manually and mechanically. With the development of science and technology, manual welding is gradually eliminated, and mechanical welding gradually replaces the market. Mechanical welding has a series of advantages such as high efficiency and precision. Among them, when welding metal pipes, generally, the pipes are fixed by a fixing device and then welded by a welding device. However, in this process, the fixing method of the fixing device is relatively complicated, which leads to the installation and removal of the pipes. It is more time-consuming, and the price of precision fixtures is also relatively expensive, which greatly increases the production cost of the enterprise
