Abstract

Processed springs steel wire rope is the utility model is related to, forms the steel wire rope of 1*3 structures, a diameter of 1.0mm 1.6mm of rope making wire by torsade equipment primary twisting by three isodiametric rope making wires.Gained steel wire rope has to pass through swage deformation process, fully to eliminate stress caused by twisting, ensures that the flatness of steel wire rope and linearity are good.The utility model diameter is close with traditional individual wire diameter.The utility model reduces the diameter of individual wire in steel wire rope by increasing steel wire radical, increases the tensile strength of individual wire；With the utility model processed springs, its linearity, pliability are more preferable, and tensile strength is high, it is remarkably improved the fatigue behaviour of steel wire rope spring, fracture of wire defect during spring Coil-up processing is reduced, the service life of spring is improved, can also reduce the raw materials consumption of spring production.The utility model is mainly used in the processing of spring used in padding for spring bed, Sofa mattress, seat cushions etc..

Description

Processed springs steel wire rope

Technical field

A kind of processed springs steel wire rope is the utility model is related to, particularly one kind is mainly used in padding for spring bed, vapour The spring steel cord in the field such as vehicle-seat cushion and Sofa mattress.

Background technology

For the spring in the fields such as padding for spring bed, Sofa mattress, seat cushions, conventional method be using diameter compared with The single processing of big steel wire, because of being relatively large in diameter for individual wire, it may appear that problems with：Single steel wire is harder, not only adds Work is difficult, steel wire brittle fracture easily occurs during processed springs are made；Single wire spring fatigue toughness is poor, easily becomes Shape, spring service life are shorter.

Spring steel wire intensity such as common 3.0mm is relatively low, generally 1580MPa, and steel wire torsion number is minimum 16 times, by The factors such as production equipment technique restrict, and its performance indications is difficult to have raising by a relatively large margin；Simultaneously 3.0mm steel wire spring around Steel wire fracture occurs in system risk when processing is higher, and product quality hidden danger is larger.

CN102383322A discloses a kind of steel wire rope, including central strand and outer layer strand, the number of outer layer strand for six strands simultaneously Uniformly bag is twisted with the fingers in the outside of central strand, and the central strand is single, central stock made of nylon material.

The content of the invention

The purpose of this utility model is the above-mentioned present situation of pin, it is intended to which a kind of intensity of development ＆ production is high, good toughness and fatigue proof Processed springs steel wire rope.

The implementation of the utility model purpose is processed springs steel wire rope, is passed through by three isodiametric rope making wires Cross the steel wire rope that torsade equipment primary twisting forms 1*3 structures, a diameter of 1.0mm-1.6mm of rope making wire.

Diameter of the present utility model is close with traditional individual wire diameter.The utility model is by increasing steel wire radical To reduce the diameter of individual wire in steel wire rope, increase the tensile strength of individual wire；Using 3 diameter identical fine wires A kind of steel wire rope is formed by twisting, for processed springs, its linearity, pliability are more preferable, and tensile strength is high, is remarkably improved steel The fatigue behaviour of cord spring, fracture of wire defect during spring Coil-up processing is reduced, the service life of spring is improved, can also reduce The raw materials consumption of spring production.The utility model is mainly used in spring used in padding for spring bed, Sofa mattress, seat cushions etc. Processing.

Brief description of the drawings

Fig. 1 is the utility model structure diagram,

Fig. 2 is the spring structure schematic diagram processed by the utility model.

Embodiment

The utility model is described in detail with reference to the accompanying drawings.

Reference picture 1, the utility model are tied by three isodiametric rope making wires by torsade equipment primary twisting into 1*3 The steel wire rope of structure, a diameter of 1.0mm-1.6mm of rope making wire.

The utility model is a kind of high-performance steel cord of new structure.Gained steel wire rope is had to pass through at swage deformation Reason, fully to eliminate stress caused by twisting, ensures that the flatness of steel wire rope and linearity are good.

By the spring structure of the utility model processing as shown in Fig. 2 spring presses S-shaped direction with 6-6.5 times of tight pitch It is twisted, the number of steel wire torsion is more than 20 times.

Spring linearity that the utility model is processed, pliability are good, and tensile strength is high.

The present invention is described in detail with specific embodiment below.

Embodiment 1, by three 1.4mm equal diameters rope making wires 1 by S-shaped direction with pitch 18.5 ± 0.5mm closing lays Into preformed wire rope 2 as shown in Figure 1, its steel wire rope nominal diameter is 3.0mm.

Ordering-the embodiments, because its individual wire diameter by original 3.0mm is reduced to 1.4mm, intensity of steel wire is carried by 1580MPa Up to 1770MPa, even more high, steel wire torsion number are brought up to minimum more than 20 times by minimum 16 times.For processing simmons Mattress spring, its linearity, pliability are more preferable, and tensile strength is high, are remarkably improved the fatigue behaviour of spring, reduce spring Coil-up Fracture of wire defect during processing, the service life of spring is improved, can also reduce the raw materials consumption of spring production.

Embodiment 2, it is twisted by 3 1.0-1.4mm equal diameters rope making wires 1 by S-shaped direction with 6-6.5 times of tight pitch Into preformed wire rope 2 as shown in Figure 1, its steel wire rope nominal diameter is 2.2-3.0mm.Intensity of steel wire 1770MPa, steel wire are turned round Turn number more than 24 times, available for processing padding for spring bed spring.

Embodiment 4, it is twisted by 3 1.4-1.6mm equal diameters rope making wires 1 by S-shaped direction with 6-6.5 times of tight pitch Into preformed wire rope 2 as shown in Figure 1, its steel wire rope nominal diameter is 3.0-3.5mm., intensity of steel wire 1770MPa, steel wire Number of torsions more than 20 times, available for processing seat cushions spring.
