An industrial flexible cable

Abstract

The invention discloses an industrial flexible cable, which relates to the technical field of cable manufacturing, comprising a sheath layer and a plurality of wire cores arranged in the sheath layer, and the inside of the sheath layer is arranged along the length direction of the cable and coaxially with the cable There is an elastic filling strip, the cross section of the elastic filling strip is polygonal, and each side is sunken inward, forming a placement channel for placing the wire core with the inner side wall of the sheath layer; The inner side wall of the sleeve layer is abutted; the elastic filling strip is spirally arranged around its axis. By setting the elastic filling strip inside the cable, when the core in the sheath is stretched or twisted, it will shrink toward the axis of the sheath layer, that is, compress the above elastic filling strip, because the elastic filling strip itself can face It shrinks by itself, so that the tensile force or torsion force on the core can be converted into a partial displacement of the core itself, thereby avoiding damage.

Description

technical field [0001] The present invention relates to the technical field of cable manufacturing, more specifically, it relates to an industrial flexible cable. Background technique [0002] Industrial robots are multi-joint manipulators or multi-degree-of-freedom machine devices for the industrial field. Robot cables are the "blood vessels" and "nerves" of robots, and are important parts of robots. During the operation of industrial robots, there will be reciprocating relative motions at various angles between the joint manipulators. This puts high demands on the torsional performance of the cables between the joint manipulators. Special cables for robots with high flexibility, bending resistance, torsion resistance and long service life will surely become the first-choice cables for first-class machinery and mechanical equipment manufacturers at home and abroad. [0003] In order to improve the anti-torsion performance of the existing robot cables, the cables themselve...

Problems solved by technology

[0004] During the use of industrial robot cables, they will not only be subjected to tensile force, but also torsion force. The above-mentioned stretching and torsion operations will cause damage to the cable surface and internal core. Damage to the cable surface will affect the safety of industrial robots. and reliability, and once the inner core of the cable is damaged, the industrial robot will fail or even stop
