Novel annular pipeline welding machine

Abstract

The invention discloses a novel annular pipeline welding machine which comprises a rotary spinning roller, a wire feeding roller, a wire feeding hose, a current contact nozzle, an external spray nozzle, a secondary wind pipe, a primary wind pipe, a welding torch fixing cylinder, an electromotor, a clamping ring, a welding disc and a reduction gearbox, wherein the reduction gearbox is arranged at the right lower end of the rotary spinning roller; the welding disc is arranged at the lower right end of the rotary spinning roller; the clamping ring is arranged on an inner ring of the rotary spinning roller; the wire feeding roller is arranged on the outer side of the left end of the rotary spinning roller and is connected with the primary wind pipe through the wire feeding hose; the welding torch fixing cylinder is arranged at the lower end of the primary wind pipe; the lower end of the welding torch fixing cylinder is connected with the secondary wind pipe; the lower end of the secondary wind pipe is connected with the external spray nozzle; the lower end of the external spray nozzle is connected with the current contact nozzle; and the electromotor is arranged beside the welding torch fixing cylinder. The novel annular pipeline welding machine is reasonable in design, excellent in welding effect, high in safety performance, long in service life, and suitable for popularization and application.

Description

technical field [0001] The invention relates to a welding machine, in particular to a novel ring type pipeline welding machine. Background technique [0002] Welding is the process of using various fusible alloys (solders) to join metal parts. The melting point of solder is lower than that of the material to be welded, so that the parts will be welded through the intermolecular contact on the surface without being melted. Now, with the development of industry, many pipes need to be welded, because the cylindrical surface of the pipe is not It is flat and difficult to weld, especially the gas generated during welding affects the vision and is not conducive to welding. Therefore, a new type of ring pipe welding machine is designed to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to provide a new type of ring-type pipe welding machine to solve the problems raised in the above-mentioned background technology. [0004] Th...
