Abstract

The utility model relates to a steel wire ring for planar steel rings. The utility model is provided with a main body, an inner foot and an outer foot, wherein the inner foot and the outer foot are bent to an equal angle in the opposite direction respectively corresponding to the main body; the inner foot is extended with a tail foot, wherein the inner side of the tail foot can be in contact with the inner wall of the steel ring when the steel wire ring is operated along the steel ring; thus, by the change of the geometric shape of the steel wire ring, the outer foot is in advance when the steel wire ring is operated, friction resistance is reduced, and the back side of the advancing direction of the steel wire ring is in contact with the steel ring in a cross mode; a non-friction gap is formed at the front end of the leading edge direction, a smooth passage of yarn is built, and the stability that the steel wire ring is operated on the steel ring is increased; simultaneously, the operating gravity center of the steel wire ring is reduced, the wearing capacity between the steel wire ring and the steel ring is small, and the pressure for the steel ring and the heat which is generated due to friction are reduced. The utility model prolongs the service life of the steel wire ring and the steel ring, delays or prevents the early coming of the decline period of the steel wire ring and improves spinning quality.

Description

The Plane Ring steel traveler

Technical field

The utility model relates to the steel traveler that a kind of that be used for ring throstle and rings constitute a pair of kinematic pair, particularly a kind of Plane Ring steel traveler.

Background technology

Steel traveler is not only and is finished the indispensable element of Yarn twisting winding, the more important thing is that producing model (geometry) and number number (weight) of going up the utilization steel traveler controls and stable spinning tension, to reach the purpose that winding shaping is good, reduce spinning end breaking.Steel traveler is high speed rotary on rings, and its linear velocity is up to 40～44m/s, and pressure is up to 372.4 * 10 ⁴Pa, fricative temperature can reach more than 300 ℃.Used PG shaped steel wire ring is comparatively general, there is shortcoming easy to wear, that the life-span is short, and the passage of the polishing scratch that produces of steel traveler and rings and yarn count intersects and the yarn card is disconnected, easily causing the sharply situation generation of increase of broken end, and promptly steel traveler has reached the decline phase.

Summary of the invention

The purpose of this utility model provides a kind of Plane Ring steel traveler, technical problem to be solved is the wear extent that reduces it and rings by the geometry that changes steel traveler, reduce its revolution center of gravity, thereby postpone or avoid the arrival of steel traveler decline phase (promptly producing a large amount of broken ends).

For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:

A kind of Plane Ring steel traveler, have main body, interior pin, outer pin, its technical scheme be described in pin, outer pin bend an angle same in the opposite direction with respect to main body respectively, interior pin extends one when steel traveler its inboard and the contacted caudal leg of rings inwall when rings move.

In the technique scheme, the inflection point of described interior pin, outer pin is preferably in the location point that is positioned at the width of measuring steel traveler.In above-mentioned pin be with respect to main body to inside and outside pin be with respect to main body outwards bend respectively one make twisted fibers obtain S twist with the fingers to angle.In above-mentioned pin can also be with respect to outside, the outer pin of main body be with respect to main body inwardly bend respectively one make twisted fibers obtain Z twist with the fingers to angle.The angle of pin, the bending of outer pin is preferably between 5 °～20 ° in above-mentioned.

Pin, outer pin bend an angle same in the opposite direction with respect to main body respectively in described in the utility model, and interior pin extends one when steel traveler its inboard and the contacted caudal leg of rings inwall when rings move.Like this, by changing the geometry of steel traveler, outer pin is leading when making the steel traveler operation, on direction of advance, form the fore trend that comes back, reduced frictional resistance, causing the rear side of the direction of advance of steel traveler to intersect with rings simultaneously contacts, direction comes back ahead of the curve, form non-friction gap (reason that the β dihedral becomes among Here it is Fig. 5), thereby built the happy passage (being not) of yarn to add the passage that the great circle type causes " spaciousness ", this happy passage is a kind of cross aisle of solid, and it can reduce the distance of the application point and the rings frictional resistance point of yarn take-up force to greatest extent, increases the stability that steel traveler moves on rings.Moreover operation is raised in the steel traveler front, is back at steel traveler by the position of abrasion, and the wear extent of itself and rings is less, postpones or avoided the too early arrival of steel traveler decline phase (promptly producing a large amount of broken ends).Interior pin extends one and the contacted caudal leg of rings inwall, reduced the operation center of gravity of steel traveler, it is operated steadily, improved spinning quality, because the wearing and tearing of caudal leg have increased the smooth wear surface of smooth surface, reduced steel traveler effectively to the pressure (pressure) of rings and because fricative heat, reduce very important thermal wear, prolonged the service life of steel traveler (with rings) greatly.In sum, the utility model changes according to the tension force (winding tension and balloon tension) of spinning, adopt to postpone the steel traveler decline phase too early arrival, reduce its revolution center of gravity, the measures such as resistance of reducing friction are to satisfy the three high needs of " high yield, high-count, high-quality " that fine spining machine produces.Through test, the utility model can increase the weight of steel traveler 1～2 number under the situation of same ingot speed and identical spinning count, more can improve its service life.
