Abstract
A kind of device improving conductor strand roundness, including strand bow, is provided with some magnetic eyes on described strand bow；The magnetic eye at strand bow two ends is maximum with the radial distance of strand bow, and the radial distance toward middle then magnetic eye with strand bow is gradually reduced, and the spacing between magnetic eye progressively reduces.In apparatus of the present invention, the hollow state of copper cash is kept as the best, and twisted wire quality is the highest.
Description
Technical field
The invention belongs to cable manufacture field, be specifically related to a kind of conductor strand roundness improved
Device and method.
Background technology
Conductor strand be with stranded single line around twisted wire axis constant angular velocity rotate and twisted wire at the uniform velocity before
Enter what motion realized. the single copper wire on draw drum is worn from noseplate by two to three row's guide wheels
Cross, be then passed through strand bow to take-up reel take-up.Man-hour is added at small-sized round wires cross-sectional area of conductor electric wire,
Twisted wire is generally divided into regular stranded and informal stranded (i.e. restrainting strand) two kinds.Regular stranded refer to list
Line is with twisted wire centrage as axis, and layering is stranded in about in an orderly manner, adjacent twisted layer direction phase
Instead, central core can be made up of single or several single lines, and with equal diameter that central core is 1
The twisted wire of single line is most common, this stranded also known as concentric lay.Bundle strand refers to many single lines
With equidirectional, with the not stratified ground of pitch stranded mode twisted together, be characterized in each single line
Relative position in goods is not fixing and orderly.
Conventional strand bow design arrangement scheme: the strand that equipment manufacturers use at present bent copper cash device
Have multiple, but major part uses and is equidistantly contained in by magnet ring on strand bow.Strand bow and the position of magnet ring
Put and distance is fixing, be linked to be a section string between each magnet ring, so run
Just feel it is not much smoother, the stranded roundness of copper wire can be largely effected on.
Summary of the invention
It is an object of the invention to provide a kind of device and method improving conductor strand roundness,
The hollow state of copper cash is kept as the best, and twisted wire quality is the highest.
A kind of device improving conductor strand roundness, including strand bow, it is characterised in that: in institute
State strand bow and be provided with some magnetic eyes；The magnetic eye at strand bow two ends is maximum with the radial distance of strand bow, past
The radial distance that middle then magnetic eye and strand are bent is gradually reduced, and the spacing between magnetic eye progressively contracts
Little.
Further, the two ends at described strand bow are provided with guide wheel；Described guide wheel is from the radial direction of strand bow
Distance is had hallucinations more than magnetic and is twisted the radial distance of bow, is applicable to big square of line herein.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention 1；Fig. 2 is the embodiment of the present invention 2
Structural representation；In figure, a, copper cash, 1, strand bow, 2, magnetic eye, 3, guide wheel.
Detailed description of the invention
Embodiment 1
A kind of device improving conductor strand roundness, including strand bow 1, on described strand bow 1
It is provided with some magnetic eyes 2；The magnetic eye at strand bow two ends is maximum with the radial distance of strand bow, toward centre then
Magnetic eye is gradually reduced with the radial distance of strand bow, and the spacing between magnetic eye progressively reduces.
Said apparatus is used primarily in 500 type wire twisting machines, is suitable for stranded small bore (≤1.25mm2)
Conductor.Sliver will become smoother, and whole curve becomes close to " steepest curve " i.e.
Being exactly the shape of " cycloid ", sliver can be made to run more smooth and easy, twisted wire roundness also can simultaneously
Obtain best state.
A kind of method improving conductor strand roundness, the speed of 500 type wire twisting machines is 1500
The when of-1800rpm, whole piece copper cash a runs through the magnetic eye on strand bow.The hollow state of copper cash
It is the best to be kept as, and twisted wire quality is the highest.
Embodiment 2
A kind of device improving conductor strand roundness, including strand bow 1, at described strand bow 1
Two ends are provided with guide wheel 3；Described guide wheel 3 bends from strand more than magnetic eye 2 from the radial distance of strand bow 1
The radial distance of 1；The magnetic eye at strand bow two ends is maximum with the radial distance of strand bow, toward centre then magnetic
Eye is gradually reduced with the radial distance of strand bow, and the spacing between magnetic eye progressively reduces.
Said apparatus is used primarily in 630 type wire twisting machines, is suitable for stranded heavy in section (＞ 1.25mm2)
Conductor, to ensure that big square of line reaches hollow state.
A kind of method improving conductor strand roundness, the speed of 630 type wire twisting machines is at 800-
The when of 1000rpm, whole piece copper cash a runs through the guide wheel on strand bow and magnetic eye.Whole piece copper cash
Hollow state is kept as the best, and twisted wire quality is the highest.
Claims (2)
1. improve a device for conductor strand roundness, including strand bow, it is characterised in that: on described strand bow, it is provided with some magnetic eyes；The magnetic eye at strand bow two ends is maximum with the radial distance of strand bow, and the radial distance toward middle then magnetic eye with strand bow is gradually reduced, and the spacing between magnetic eye progressively reduces.
A kind of device improving conductor strand roundness the most according to claim 1, it is characterised in that: it is provided with guide wheel at the two ends of described strand bow；Described guide wheel from strand bow radial distance more than magnetic have hallucinations strand bow radial distance.
