Description

Double-welding-wire guiding synchronous wire feeding system

Technical Field

The invention belongs to the technical field of wire feeding systems, and particularly relates to a double-welding-wire guiding synchronous wire feeding system.

Background

Unlike conventional gas shielded arc welding, two wires extend in parallel from two guide nozzles or a single double wire single arc welding contact nozzle (e.g., CN 218903933U), respectively, during double wire single arc welding.

In the prior art, a dual-drive wire feeder is generally used for feeding two welding wires, namely two groups of wire feeding wheels and a compression wheel are used for feeding two welding wires with the same wire diameter, each welding wire can pass through the two groups of wire feeding wheels and the compression wheel, the wire feeding precision and the wire feeding stability of the dual welding wires are enhanced through the dual wire feeding wheels and the compression wheel, and finally the two welding wires are fed into a wire feeding pipe.

However, the prior art does not have a wire feeding pipe special for double-wire single-arc welding, and the wire feeding pipe obtained by double-wire single-arc welding is only marginally suitable for a special welding machine, is used for welding straight seams, and cannot be used for welding non-straight seams on a welding robot, such as circular arc welding. Because when the welding robot welds the nonlinear seam, the welder on the robot will change the gesture and turn to, and this is that one of them welding wire in the wire feed pipe will produce undulant, and undulant welding wire in the wire feed pipe will be influenced for undulant welding wire influences another welding wire, and two welding wires friction knot in the wire feed pipe are hung, and the welding wire is hung the back, and the wire feed speed of two welding wires will produce the difference, and the electric arc will be pulled apart, produces and splashes, influences the welding effect.

In addition, in the production process (such as drawing) of the welding wire, due to unavoidable factors such as processing errors, material substances and the like, a part of the wire diameter of the welding wire is larger, or the welding wire can be interrupted in the drawing process of the welding wire, the interrupted welding wire can not be discarded, and the interrupted welding wire can be connected with another welding wire, so that the size of the joint of the two welding wires is larger than the standard wire diameter of the welding wire. When the welding wires with larger wire diameters pass through the wire feeding wheels in the wire feeding process, the pressing wheels and the wire feeding wheels of the same group jack up, so that the thrust and friction of the pressing wheels and the wire feeding wheels of the same group to the other welding wire are reduced, the other welding wire slips, the wire feeding speeds of the two welding wires are inconsistent, the two welding wires cannot be synchronous, and the integral welding effect is affected.
