Abstract

The utility model discloses a wear-resistant and anti-torsion drag-chain cable, comprising conductors, an insulating layer, a reinforcing core, a reinforcing layer and jackets. The wear-resistant and anti-torsion drag-chain cable is characterized in that: the conductor is formed by twisting a plurality of bundled conductive single wires, an elastic polyester insulating layer is wrapped outside the conductor by extrusion, and a plurality of conductors wrapped with the insulating layers are twisted into a composite twisted unit group; the reinforcing core formed by twisting a plurality of nylon wires is disposed at the centre of the cable, and twisted into a cable core with a plurality of composite twisted unit groups uniformly distributed in the periphery; and the inner jacket made from TPE (thermoplastic elastomer) material is wrapped outside the cable core by extrusion, the reinforcing layer formed by compositely weaving aramid fibre wires with tin-plated copper wires is disposed outside the inner jacket, and the outer jacket made from PUR (polyurethane) material is wrapped outside the inner jacket by extrusion. The wear-resistant and anti-torsion drag-chain cable has the capacities of high mechanical stress, high alternate bending frequency and high wear resistance, as well as is suitable for long-term reliable operation at working environment temperature ranging from minus 45 DEG C to 45 DEG C.

Description

Wear-resisting anti-rotational drag chain cable

Technical field

The utility model relates to a kind of drag chain cable, particularly relates to a kind of anti-high flexibility drag chain that dynamically circumnutates and uses cable.

Background technology

Along with the high speed development of industrial automation control appliances such as automated machine tool, delivery groups wiring, robot, hoisting equipment, increasingly high to its attached supporting drag chain system requirements.The important component part of drag chain system is exactly a drag chain cable; Homemade existing drag chain cable lacks the structural design of high flexibility and warp resistance because of it; Flexibility is not enough in the use, and tensile strength is little, is prone to cause defectives such as fracture, wearing and tearing; Be difficult to adaptation equipment high speed, the multi-direction specification requirement that adds distortion, the also main at present dependence on import of moving.Develop rapidly a kind of have anti-ly dynamically circumnutate, high-wearing feature; Also have oil resistant, uvioresistant, not halogen-containing simultaneously; And installing space is little, the cable of long service life, and can substitute import, becomes a urgent task of cable R&D institution and manufacturing enterprise.

The utility model content

The purpose of the utility model is the above-mentioned defective that exists to prior art; A kind of anti-wear-resisting anti-rotational drag chain cable that dynamically circumnutates is proposed; Employing is with the conductor strands; Increase the new design of compound reinforced layer, can under the state that dynamically circumnutates, use, the problem that has solved that easily broken core in the drag chain system high-speed motion process, sheath are easy to wear, twisted in the cable running.

The technical scheme that the utility model solution prior art weak point is taked is: a kind of drag chain cable; Comprise conductor, insulating barrier, strengthening core, reinforced layer, sheath; It is characterized in that: conductor is by stranded the forming of multiply bunchy conductive monofilament; Conductor is extruded with the elastic polyester insulating barrier outward, and the plurality of conductors that is surrounded by insulating barrier is twisted into multiple strand unit group again; Cable center establishes by the stranded strengthening core that forms of multiply nylon yarn, is twisted into cable core with equally distributed some unit groups of twisting again on every side; Cable core is extruded with TPE material inner sheath outward, and the inner sheath peripheral hardware is extruded with PUR material oversheath by aramid fiber silk and the composite braided reinforced layer that forms of tinned copper wire outside it.

Each twists the unit group again by 2～4 bursts of stranded forming of conductor.

The quantity of twisting the unit group again is 4～8.

The beneficial effect of the utility model is: the utlity model has special structure design and suitable material selection, make cable possess excellent weather resisteant, resistance to wear and oil resistant characteristic.When equipment runs up, have the ability of high mechanical stress, high alternating bending frequency and high abrasion, can adapt to-45 ℃～45 ℃ operating ambient temperature, reliably and with long-term operation.

Embodiment

Below in conjunction with accompanying drawing and embodiment, the utility model is further described.

The cross-section structure of the wear-resisting anti-rotational drag chain cable of the utility model as shown in Figure 1, conductor 1 is by 6 types of stranded forming of conductive monofilament of multiply bunchy, and conductor is extruded with elastic polyester insulating barrier 2 outward, and the plurality of conductors that is surrounded by insulating barrier is twisted into multiple strand unit group 4 again.Each twists the unit group again can be by 2～4 bursts of stranded forming of conductor, and this example is selected 3 strands for use.The conductive monofilament diameter is thin more, and the flexibility of conductor is just high more.Conductor adopts the stranded mode of this first Shu Hehou to process, thereby has guaranteed the necessary cohesiveness of conductor, makes conductor both have good flexibility, has suitable bending resistance folding endurance again.Insulating barrier is selected for use has high mechanical properties, and the polyester elastomer materials extruded of suitable thin-walled, and thin-walled extrudes that to make cable reach external diameter littler, the purpose that weight is lighter.Cable center establishes by multiply high-strength nylon skein silk and closes the strengthening core 3 that forms, and is twisted into cable core with equally distributed some unit groups of twisting again on every side.The quantity of twisting the unit group again is 4～8, and this example is selected 6 for use.Cable core is extruded with high strength TPE material inner sheath 5 outward, and the inner sheath peripheral hardware has shielding action simultaneously by aramid fiber silk and the composite braided reinforced layer that forms 6 of tinned copper wire.It is outer to be extruded with high abrasion, high strength, tear-resistant PUR material oversheath 7.Utilize plsitive mold, inner sheath, reinforced layer, oversheath are combined together, have more anti-torsion ability.
