Problems solved by technology

However, in applications with larger spans or heavy loads, the self-weight of long and thicker cable strands becomes a burden on the overall structure, and affects the application and cable force transmission of larger spans.

Embodiment

[0079] The present invention can be used for producing the ultra-high strength (more than 2000MPa) micro-strand production method, comprises the steps:

[0080] 1) Hoist the I-shaped wheel equipped with micro-steel wires with a diameter of 0.3 to 3.0mm to the pay-off frame, push and lock the thimble, and several micro-spools are loaded one by one according to this;

[0081] 2) Pass the micro-fine steel wire along the guide wheel, and pass through the corresponding holes of the combing reels at all levels in turn, to the joint; according to the production needs, choose whether the twist angle of the steel wire is required, and the angle of the combing reels Step-by-step adjustments in proportion;

[0082] 3) Fix all the fine wires gathered at the joint into one strand (connect or weld with metal perforated plates, and make the steel wires densely packed);

[0083] 4) Pull the fine silk strands to the take-up reel and fix them, and wrap the strands on the fixed length of the st...

Abstract

The invention discloses a method and a device for manufacturing a cable by using micro steel wires. The method comprises the following steps: stacking and paying off, wire separating and combing, tension control, stranding, winding, clamping and pulling, cutting and taking up, wherein in the step of stacking and paying off, the diameter of the steel wire for paying off ranges from 0.03 mm to 3.0 mm, and spools are adopted for paying off and are arranged in a multi-layer and multi-column stacking mode; in the step of wire separating and combing, at least four wire separating and combing discs are adopted and evenly arranged between paying-off and stranding at intervals, and all the wire separating and combing discs sequentially deflect by an angle along the axis, so that the steel wires are adjusted step by step in the circumferential direction for multiple times, and thus a torsional angle is achieved through accumulation; wire holes are uniformly formed in the wire separating and combing discs, the wire holes are in fillet transition, and R is larger than 10 mm; and the wire separating and combing discs are made of a non-steel material. According to the method, the ultrahigh-strength fine steel wires are used for manufacturing the cable, under the same cable force requirement, the cable strand sectional area (diameter) is reduced, the porosity is reduced, the cable strand compactness is improved, meanwhile, the cable strand dead weight is reduced, and the spanning capacity of the cable is enhanced.

Description

technical field [0001] The invention relates to the technical field of making steel wire strands, in particular to a method and a device for making a fine steel wire cable. Background technique [0002] Steel wire strands are widely used in the field of industrial and civil construction, mainly including: bridge cable structure, stadium cable, etc. The design of the cable strand structure is slightly different depending on the stress occasion. Angle torsion angle; stadium cables are generally made of multi-layer steel wire twisted strands, or can be called twisted wires. Steel wire strands are designed with corresponding diameter, length, strength, anti-corrosion and other properties according to the requirements of span or space. At present, there are two product application cases for bridge slings, one is parallel steel wire strands (small twist angle), the steel wire specification is mostly 5.0mm, and the conventional tensile strength is 1770-1860MPa; the other is steel ...
