Problems solved by technology

[0002] At present, the head of the steel pipe multi-wire internal welding machine mostly uses a wire feeding hose to connect the welding torch. It is difficult to reduce the bending radius of the wire feeding hose ρ, and the wire feeding resistance increases; at the same time, it is limited to the inherent length of the welding torch, and the position adjustment is difficult, making it difficult to realize the internal welding of small diameter tubes with multiple wires and large straight seams

Abstract

The invention provides a steel tube multiple-wire internal welding machine nose comprising a soldering flux cylinder, a wire feeding panel, wire guide wheels and contact tubes, wherein a plurality of wire guide wheels are regularly distributed on the front side of the wire feeding panel to form a plurality of wire guide channels, a connection rear panel is lined at the back side of the wire feeding panel, and the wire guide wheels are fixed with the connection rear panel after passing through the wire feeding panel; a wire guide connector is arranged on the wire feeding panel, a welding nozzle plate is connected under the wire feeding panel, the welding nozzle plate is respectively welded with welding nozzle blocks, each welding nozzle block is internally connected with a contact tube by threads, and the upper port of each contact tube is in butt joint with the wire guide channels. In addition, the soldering flux cylinder is arranged on the wire feeding panel, a discharging hole of the soldering flux cylinder just faces to the lower ports of the contact tubes. The device can realize large straight seam welding of a small internal diameter steel pipe and is worthy of being widely popularized and applied in the industry.

Description

technical field [0001] The invention relates to a head device of a steel pipe multi-wire internal welding machine, which belongs to the technical field of steel pipe welding machinery and equipment. Background technique [0002] At present, the head of the multi-wire internal welding machine for steel pipes mostly uses a wire feeding hose to connect the welding torch, and the wire feeding hose is difficult to bend. It is difficult to reduce the bending radius of the wire feeding hose ρ, and the wire feeding resistance increases; at the same time, it is limited to the inherent length of the welding torch, and the position adjustment is difficult, making it difficult to realize the internal welding of small diameter tubes with multiple wires and large straight seams. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a head device of a multi-wire internal welding machine for steel pipes.
