Wire feeder

Abstract

The invention discloses a wire feeder which comprises an upper cover, a machine body, a stepping driving mechanism, wire feeder bodies and a positioning mechanism, wherein the stepping driving mechanism is mounted in the machine body; fixed-length output of a welding wire is realized by the aid of the arrangement of the stepping driving mechanism; the upper cover and the machine body are connected in an opening and closing manner; an opening and closing mechanism is arranged, so that the upper cover can be flexibly opened or closed, and auxiliary-penetration of welding wires at a wire feeding stage is realized; at least two wire feeder bodies are provided, and the wire feeder body comprises two wire guides fixed on the machine body and a wire feeding gear; through holes are formed in both wire guides; the through holes are located on the same horizontal axis after the wire guides are fixed; the wire feeding gear is arranged between the wire guides and connected with the stepping driving mechanism; the positioning mechanism is mounted in the upper cover and located above the wire feeding gear, and can be closely combined with the wire feeding gear during working; according to the wire feeder, the upper cover can be opened, wire penetration is facilitated, the work continuity is high, fixed-length output of the welding wires is realized, the production efficiency is improved, and waste is avoided.

Description

technical field [0001] The invention relates to the field of welding equipment, in particular to a wire feeding mechanism of a welding machine. Background technique [0002] The welding machine is equipped with a wire feeding mechanism to realize automatic production, but the fuselage of the wire feeding mechanism in the prior art is integrally formed, and manual wire threading before welding cannot observe the wire threading situation in real time. It is easy to bend when bending, and needs to be repeatedly interspersed, which cannot ensure a 100% success rate, and the operation is cumbersome and complicated; the existing wire feeding mechanism is only equipped with a wire feeding gear, and the welding wire is likely to be displaced when the welding machine is working , thereby affecting the quality of welding; in addition, the existing wire feeding mechanism can only coordinate with one welding machine, and its work efficiency is low and the cost is high; in addition, the ...
