Abstract

An annular numerical control electric welding machine comprises a plurality of arc welding blocks, and an annulus is defined by the arc welding blocks; output openings are formed in the arc welding blocks, and the multiple output openings are small hollowed holes arranged in order; the arc welding blocks are hollow shells, and each shell is divided into two layers; each arc welding block comprises a left arc block body and a right arc block body which are connected into a whole; the middles of the arc welding blocks are connected with a sliding mechanism, and the left arc block bodies and the right arc block bodies are provided with tin feeding mechanisms; the sliding mechanism and the tin feeding mechanisms are fixed to a rotating plate through a plurality of fixing rods; and each tin feeding mechanism comprises a cavity, discharging openings are formed in the cavities, and the discharging openings are connected to a main feeding opening through a plurality of connecting rods. The annular numerical control electric welding machine has the beneficial effects that two round pipes are in butt joint precisely, full-automatic welding and tin solder adding are achieved, and the welding machine is suitable for large round pipes with various diameters.

Description

technical field [0001] The invention belongs to the field of welding, and in particular relates to a numerically controlled annular electric welding machine. Background technique [0002] At present, when a large-sized workpiece is placed on a metal shaft for girth welding, for example, when welding between two round pipes, manual operations are generally adopted. At this time, it is necessary to use tooling to fix the workpiece, and then the worker welds it around the metal shaft. In this way, the workers move in circles while welding, and the size of the workpiece is large, which is very unfavorable for operation, and it is difficult to ensure the welding quality. [0003] Usually, with the existing manual welding, the appearance of the weld seam is not beautiful, and the weld seam is unavoidably not straight, and welding defects such as uneven weld width, undercut, burn-through, and incomplete penetration are prone to occur, and due to The diameter of the workpiece is d...
