A rail matched with a vertical frame is arranged on a cross beam support, a welding flux container is fixed to the vertical frame and arranged on one side of a welding wire, one end of a conductive copper rod is horizontally arranged at the lower end of the welding wire, a conductive rod is arranged on the lower surface of the conductive copper rod, and a through hole is formed in the conductive copper rod; the outer wall of a guide pipe of the welding wire on the upper portion is laid in the through hole, the outer wall of the conductive rod on the lower portion is laid in the through hole, the welding wire is perpendicular to the conductive rod, a square tube wraps the conductive copper rod and abuts against the conductive rod and the welding wire, a secondary cable is arranged in an inner cavity of the square tube and abuts against the conductive copper rod, a locking rod is arranged on the upper surface of the square tube, and a rotating shaft is arranged on the lower surface of the square tube; and an insulating plate is installed in the square tube, a power box output wire is connected with the secondary cable, and a power box ground wire is connected with the ground. Front-back fine adjustment can be achieved, front-back fine adjustment is achieved when the positions of the welding machine head conductive rod are not synchronous front and back, the consistency of multi-machine-head welding is guaranteed, and deposited metal backflow in the welding process is reduced.

Description

Technical field[0001]The present invention relates to the field of submerged arc welding, and more particularly to a submerged arc welding mechanism.Background technique[0002]At present, the head of the burying carrier is divided into a small difference. Whether the wire motor is in the form of a vertical delivery form or a horizontal transmission form, the wire feed mechanism is supported by a fixed bracket, and the soldering secondary line is connected to the solder rod below. The head is relatively fixed, and if there is a single head position, or when the weld layer increases, the relative offset position needs to be adjusted, only the remaining welding machine heads can only be arcped through the blade of the melon frame. The way of movement is adjusted, the operation is more troublesome, increase the number of connections, affects the quality of the welding; the temperature of the welding machine is arranged outside the support rod, the temperature of the temperature is prone ...

AI Technical Summary

Problems solved by technology

[0002] At present, the welding head of the submerged arc welding machine is similar. No matter whether the wire feeding motor adopts vertical wire feeding or horizontal wire feeding, the wire feeding mechanism is supported by a fixed bracket, and the conductive rod below it is connected to the welding secondary line. The head is relatively fixed. If there is a single head position relatively behind, or when the relative offset position needs to be adjusted with the increase of the welding layer, all other welding heads can only stop arcing and pass through the front of the gantry frame of the special submerged arc welding machine. Adjustment by means of shifting, the operation is more troublesome, the number of joints is increased, and the welding quality is affected; because the secondary line of the welding machine is arranged on the outside of the support rod, the temperature is high, and the insulation part is prone to electrical connection problems, and the failure rate increases, which affects the continuity of production conduct
