An integrated cable special for welding machine and a manufacturing method thereof

Abstract

A special integrated cable for welding machine features that wear-resisting sleeve, rubber sleeve, high-voltage heat-shrinkable pipe and connecting protection unit are installed at both ends of the cable, and the wear-resisting sleeve is provided with a plurality of sleeves respectively wrapped on the outside of control wire, conductor wire and trachea. The abrasion-resistant sleeve and the protective sleeve are wound and connected through an insulating adhesive tape; Rubber sheath is covered with insulating tape; The outer sleeve of the rubber sleeve is provided with a high-pressure heat shrinkable pipe; The connection protection unit comprises an abrasion-resistant joint and a limit spring, wherein one end of the abrasion-resistant joint is fitted and sleeved on the exterior of the high-voltage heat shrinkage pipe, and the other end is embedded with a limit spring for limiting the bending degree of the integral cable. The integrated cable not only realizes the three-wire-in-one function of the traditional welding machine cable, Moreover, the connector of cable, wire feeder and welding machine can be disassembled quickly, which prevents the cable connector from rubbing against thewire feeder and welding machine, and prevents the signal interruption and even gas leakage caused by excessive bending of cable, thus realizing the advantages of convenient, quick and automatic operation of integrated cable, and high safety performance.

Description

technical field [0001] The invention belongs to the technical field of cable manufacturing, and in particular relates to a special cable for a welding machine, in particular to a special integrated cable for a welding machine and a manufacturing method thereof. Background technique [0002] In automatic welding equipment, the welding cables used in traditional carbon dioxide shielded welding are mostly combined cables made of air pipes, current conductor lines and multiple signal lines bound together with adhesive tape. There are many defects in this combined cable: 1. Intricate and easy to cause mutual interference of signals; 2. Inconvenient operation, the process of binding cables is time-consuming and laborious, which cannot meet the requirements of rapid processing; 3. Under high-frequency operating conditions, both current conductor lines and signal lines will heat up, which will lead to clustering in severe cases. The vinyl chloride insulation protection cover melts, ...

[0002] In automatic welding equipment, the welding cables used in traditional carbon dioxide shielded welding are mostly combined cables made of air pipes, current conductor lines and multiple signal lines bound together with adhesive tape. There are many defects in this combined cable: 1. Intricate and easy to cause mutual interference of signals; 2. Inconvenient operation, the process of binding cables is time-consuming and laborious, which cannot meet the requirements of rapid processing; 3. Under high-frequency operating conditions, both current conductor lines and signal lines will heat up, which will lead to clustering in severe cases. Vinyl chloride insulation cover melts, even leakage or line fusing

[0005] After comparative analysis, although the above-mentioned published patent has solved the problem of three wires in one of the traditional cable, it has not made any improvement in the splitting of the two ends of the cable and how to connect with the wire feeder and welding, and there are still the following defects: in the cargo ship hull When in use, a longer cable is required due to the larger hull, and the nearly closed space inside the hull is not conducive to the volatilization of carbon dioxide gas. At this time, if the cable in the above patent is directly connected to the wire feeder and welding machine, it is very easy to cause the cable Friction with the fixed structure on the wire feeder and welding machine will cause the cable to break and even carbon dioxide to leak, thus endangering the personal safety of the crew on board
