Twin-wire dual-drive arc welding wire feeder

Abstract

The invention relates to an arc welding wire feeder, in particular to a twin-wire dual-drive arc welding wire feeder. The wire feeder comprises a motor, a speed reducer, wire feed rolls and compression rolls, wherein, an output shaft of the speed reducer is equipped with an intermediate gear; the intermediate gear is respectively meshed with two wire feed gears; the two wire feed gears are respectively and coaxially equipped with one wire feed roll; the two wire feed rolls are staggered and are corresponding to the compression rolls; the compression rolls are arranged on compression roll supports; and the compression roll supports are equipped with spring compression devices. The twin-wire dual-drive arc welding wire feeder has the beneficial effects that by utilizing a simple mechanical structure, the two wire feed rolls are driven by the same motor, thus ensuring that drive speed of the two wire feed rolls is consistent; and each welding wire is fed solely by a pair of the wire feed rolls and the compression rolls, thus solving the problem of uneven wire feed speed of the two welding wires, and achieving the purpose of stable welding.

Description

[0001] Technical field: [0002] The invention relates to an arc welding wire feeding device, in particular to an arc welding double wire and double driving wire feeding device. Background technique: [0003] At present, in terms of arc welding equipment, a single wire feeder is generally used to feed double wires, that is, two welding wires are fed by the same wire feed wheel and pressure wheel. Due to the influence of processing error and assembly accuracy, it is easy to produce unbalanced pressing force on each welding wire, and the welding wire with low pressure will slip due to insufficient friction, resulting in inconsistent speeds of the two welding wires, and even one welding wire does not feed, thus Affects welding or cannot weld. Invention content: [0004] The present invention aims to solve the problem of uneven wire feeding speed of two welding wires existing in single wire feeder feeding double wires, and provides a kind of feeding of each welding wire indep...
