Welding wire reel hub for welding wire feeder

Abstract

The invention discloses a welding wire reel hub for a welding wire feeder. The welding wire reel hub structurally comprises mode adjusting buttons, a welding wire reel hub body, a welding wire, a nameplate, a friction speed reducing mechanism, a base, a left supporting seat, a fixing bearing disc and a rotating rod, the nameplate is connected above the friction speed reducing mechanism through glue, and the friction speed reducing mechanism is provided with a bidirectional linkage mechanism, a guide driving mechanism, a depressurizing mechanism, a movement adjusting mechanism, a transmission mechanism, a stress starting mechanism, an up-down adjusting mechanism and a metal frame. The welding wire reel hub has the advantages that by adding a friction guide mechanism, friction force betweena friction block and a friction runner corresponding to the friction guide mechanism can be changed, so that unified adjustment on rotating speed of a welding wire reel is realized; when a welding wire is loose due to rotation of the welding wire reel caused by inertia, the loose welding wire can be reset to an original position through reverse rotation, and expected compactness can be maintained,so that unevenness caused by loosening of the welding wire is reduced.

Description

technical field [0001] The invention relates to a welding wire hub used for a welding wire feeder, which belongs to the field of welding wire hubs. Background technique [0002] Welding wire is used as filler metal or as conductive wire welding material at the same time. In gas welding and gas tungsten arc welding, welding wire is used as filler metal. In submerged arc welding, electroslag welding and other gas shielded arc welding , the welding wire is not only the filler metal, but also the conductive electrode. The surface of the welding wire is not coated with anti-oxidation flux. The current technology is a kind of welding wire hub. When the welding work is completed and the welding wire driving device stops, if the friction braking force is not adjusted correctly , the wire spool will cause the wire to be unwound undesirably. After the welding work is completed, the unwound and unused welding wire must be rewound by hand. In addition, when the welding work is stopped, ...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a welding wire hub for a welding wire feeder to solve the problem that if the welding wire hub is not correct when the welding work is finished and the welding wire driving device is stopped in the current technology, Adjusting the friction braking force, the wire spool will cause the wire to be unwound undesirably. After the welding work is completed, the unwound and unused welding wire must be rewound by hand. In addition, when the welding work stops, due to the wire spool Inertial rotation causes the welding wire to loosen, which will cause uneven welding, which is not conducive to long-term and effective work
