Wire Supply Cable

Abstract

The invention relates to a welding wire supply cable, characterized in that it comprises: a spherical part (110), comprising, a spherical part (119), formed on one side, combined with an assembly (113), equipped on the other side, through holes ( 114), formed through the center of the interior; the socket-shaped part (120), including the socket part (126), is formed on one side and is equipped with a spherical part joint part (125) and a joint assembly (123) inside, and is equipped on The other side, the through hole (124), is formed through the center of the other side; a plurality of roller placement grooves are equipped around the through hole (114) formed on the other side of the above-mentioned spherical member (110) and on the above-mentioned One or both sides selected around the through hole (124) formed on the other side of the socket-shaped part (120); and a plurality of rollers (400); After entering the above-mentioned roller placement groove, use the above-mentioned combination assembly (113, 123) to combine the above-mentioned spherical member (110) and the above-mentioned socket-shaped member (120) to form a cable unit (100) as a unit. The spherical part (119) is fitted into the spherical part coupling part (125) to continuously connect and extend a plurality of the cable units (100).

Description

technical field [0001] The present invention relates to a welding wire supply cable, and more particularly to a welding wire supply cable capable of supplying soft metal wire such as aluminum to a long distance by adopting a structure that can reduce supply resistance when supplying the welding wire. Background technique [0002] Usually, welding wires with diameters of 0.8, 0.9, 1.0, and 1.2 mm are mainly used for MIG welding and non-MIG welding, and the welding wires are connected by supply cables. From the wire box to the welding gun, the length of the above-mentioned supply cable usually does not exceed 6m. [0003] Since the above-mentioned welding wire is subjected to pipeline resistance when passing through the above-mentioned supply cable, it is not possible to use a long supply cable of 10 m or more. That is, because of the pipeline resistance inside the supply cable, it cannot be supplied at a stable speed, so that there may be a sudden large amount of welding wir...

AI Technical Summary

Problems solved by technology

However, even in the case of using helical springs to form the supply cable, soft metals such as aluminum can still cause supply problems due to excessive resistance

For this reason Teflon tubing is often used when doing aluminum welding, but in this case still suffers from supply resistance and is prone to tearing due to friction, resulting in replacement cycles for supply cables Problem with short wire and wire getting caught in the middle of the supply cable

[0006] Therefore, there will be a problem that the welding quality will deteriorate because the welding wire cannot be discharged uniformly from the welding torch.
