Manufacturing method of multi-wire combined welding cable

Abstract

The invention relates to a multi-wire combined welding cable typed II and a production method thereof and belongs to the technical field of cables. The multi-wire combined welding cable typed II comprises current conductors, a plurality of signal control cables, an inert gas pipe, a signal control carrier line, an outer sheath and the like. The current conductors are made by twisting a plurality of flexible oxygen-free copper wires. The inert gas pipe is made of flexible elastomer combined polyvinyl chloride insulating material. The signal control carrier line is made by twisting a plurality of annealed thin tined flexible oxygen-free copper wires. The signal control carrier line in the cable core is disposed in the inert gas pipe. The current conductors in the cable core are evenly disposed outside the inert gas pipe. The signal control cables are also evenly disposed outside the inert gas pipe. Nonwoven tape is wound on the cable core. The flexible elastomer combined polyvinyl chloride outer sheath is extruded on the tape. The multi-wire combined welding cable typed II is simple and reasonable in structure, advanced in process, and superior in product performance, is high in carrying capacity in operation and wide in operation range, provides power connection and signal connection for operation of automatic welding equipment, and is conducive to implementation of automatic welding.

Description

technical field [0001] The invention relates to a cable, in particular to a structure and a manufacturing method of a combined welding cable, and belongs to the technical field of cables. Background technique [0002] In the welding cables and current signal control lines used in automatic welding equipment and engineering machinery, the traditional welding cable technology is that the air pipe, current conductor, and multiple signal lines are all separated, and the transmission signals of multiple signal lines are easy to be confused. After manual segmental winding Work again. Especially in the shipbuilding welding industry, there are welding equipment production lines and other processes involving the welding of steel workpieces. In the welding operation, multiple signal sources are required to meet the process needs, and the dragging of continuous and frequent reciprocating motions, in which the various components of the cable are always In a state of dynamic winding mot...

AI Technical Summary

Problems solved by technology

After thousands of reciprocating movements, in the state of high current and high frequency, the copper stranded conductors of ordinary flexible cables often undergo yield fatigue, resulting in broken signals, and the signals are easy to be confused, and the sheath layer is often made of rubber material. When the layer is frequently twisted, it is prone to cracking, low temperature resistance level, and poor safety performance. During the operation, it is easy to be hung by the edges and corners because it is wound in sections, and the scene is chaotic. Therefore, high requirements are put forward for welding cables that move frequently, safety performance, long-distance operation, large carrying capacity, and cables that are not easy to be confused.

Often due to the damage of the cable, the signal is easy to be confused, resulting in the frequent shutdown of the entire production line, which is not suitable for high-power automatic welding occasions
